Manual Transmission

Manual Transmission Shift Pattern2021 Mazda3 Engine and Transmission User Manual-70

  1.  Neutral position
    The shift pattern of the transmission is conventional, as shown. Depress the clutch pedal all the way down while shifting; then release it slowly. Your vehicle is equipped with a device to prevent shifting to R (reverse) by mistake. Push the shift lever downward and shift to R.

2021 Mazda3 Engine and Transmission User Manual-71

WARNING

Do not use sudden engine braking on slippery road surfaces or at high speeds:
Shifting down while driving on wet, snowy, or frozen roads, or while driving at high speeds causes sudden engine braking, which is dangerous. The sudden change in tire speed could cause the tires to skid. This could lead to loss of vehicle control and an accident.

Always leave the shift lever in 1 or R position and set the parking brake when leaving the vehicle unattended:
Otherwise the vehicle could move and cause an accident.

CAUTION

  •  Keep your foot off the clutch pedal except when shifting gears. Also, do not use the clutch to hold the vehicle on an upgrade. Riding the clutch will cause needless clutch wear and damage.
  •  Do not apply any excessive lateral force to the shift lever when changing from 5th to 4th gear. This could lead to the accidental selection of 2nd gear, which could result in damage to the transmission.
  • Make sure the vehicle comes to a complete stop before shifting to R. Shifting to R while the vehicle is still moving may damage the transmission.

NOTE

  •  If shifting to R is difficult, shift back into neutral, release the clutch pedal, and try again.
    (With parking sensor system)
  • When the shift lever is shifted to the R position with the ignition switched ON, the parking sensor system is activated and a beep sound is heard. Refer to Parking Sensor System.

Gear Shift Indicator (GSI)
The GSI supports you to obtain optimum fuel economy and smooth driving. It displays the selected gear position in the instrument cluster as well as notifies the driver to change to the most suitable gear position corresponding to the actual driving condition.2021 Mazda3 Engine and Transmission User Manual-72

  1. Selected gear position
  2. Suitable gear position
Indication Condition
Numeral The selected gear position is displayed.
and numeral Shift up or down to the indicated gear position is recommended.

CAUTION
Do not rely solely on the shift-up/shift-down recommendations by indications. The actual driving situation might require shift operations different from indication. To avoid the risk of accidents, the road and traffic conditions have to be judged correctly by the driver before shifting.

NOTE
The GSI turns off when the following operations are performed.

  • The vehicle is stopped.
  • The vehicle is put in neutral.
  • The vehicle is driven in reverse.
  • The clutch is not fully engaged when accelerating from a stop.
  • The clutch pedal remains depressed for 2 seconds or longer while driving.

Recommendations for Shifting Upshifting
For normal acceleration, Mazda recommends these shift points:(U.S.A. and Canada)

Gear Vehicle speed
1 to 2 24 km/h (15 mph)
2 to 3 42 km/h (26 mph)
3 to 4 60 km/h (37 mph)
4 to 5 75 km/h (46 mph)
5 to 6 79 km/h (49 mph)

For cruising, Mazda recommends these shift points:
(U.S.A. and Canada)

Gear Vehicle speed
1 to 2 13 km/h (8 mph)
2 to 3 29 km/h (18 mph)
3 to 4 49 km/h (30 mph)
4 to 5 63 km/h (39 mph)
5 to 6 70 km/h (43 mph)

Downshifting
When you must slow down in heavy traffic or on a steep upgrade, downshift before the engine starts to overwork. This reduces the chance of stalling and gives better acceleration when you need more speed.

N (Neutral)
In N, the wheels and transmission are not locked. The vehicle will roll freely even on the slightest incline unless the parking brake or brakes are on.

WARNING
If the engine is running faster than idle, do not shift from N or P into a driving gear: It’s dangerous to shift from N or P into a driving gear when the engine is running faster than idle. If this is done, the vehicle could move suddenly, causing an accident or serious injury. Do not shift into N when driving the vehicle: Shifting into N while driving is dangerous. Engine braking cannot be applied when decelerating which could lead to an accident or serious injury.

CAUTION
Do not shift into N when driving the vehicle. Doing so can cause transmission damage.

NOTE
Apply the parking brake or depress the brake pedal before moving the selector lever from N position to prevent the vehicle from moving unexpectedly.

D (Drive)

Active Adaptive Shift (AAS) Active Adaptive Shift (AAS) automatically controls the transmission shift points to best suit the road conditions and driver input. This improves driving feel. The transmission may switch to AAS mode when driving up and down slopes, cornering, driving at high elevations, or depressing the accelerator pedal quickly while the selector lever is in the D position. Depending on the road and driving conditions/vehicle operations, gear

Manual Shift Mode

Manual Shift Mode The manual shift mode gives you the feel of driving a manual transmission vehicle by allowing you to operate the selector lever manually. This allows you to control engine rpm and torque to the drive wheels much like a manual transmission when more control is desired. To change to manual shift mode, shift the lever from D to M.2021 Mazda3 Engine and Transmission User Manual-80NOTE

  • Changing to manual shift mode while driving will not damage the transmission. If you change to manual shift mode when the vehicle is stopped, the gear will shift to M1. If you change to manual shift mode without depressing the accelerator pedal when driving in D range, 5th gear/6th gear, the gear will shift to M4/M5.

To return to automatic shift mode, shift the lever from M to D.

Gear position indication

The numeral for the selected gear illuminates.

NOTE

  • If the gears cannot be shifted down when driving at higher speeds, the gear position indication will flash twice to signal that the gears cannot be shifted down (to protect the transmission). If the automatic transmission fluid (ATF) temperature becomes too high, there is the possibility that the transmission will switch to automatic shift mode, canceling manual shift mode and turning off the gear position indication illumination. This is a normal function to protect the AT. After the ATF temperature has decreased, the gear position indication illumination turns back on and driving in manual shift mode is restored.

Manually Shifting Up
You can shift gears up by operating the selector lever or the steering shift switches*. M1 → M2 → M3 → M4 → M5 → M6

Using selector lever
To shift up to a higher gear, tap the selector lever back + once.2021 Mazda3 Engine and Transmission User Manual-81Using steering shift switch
To shift up to a higher gear with the steering shift switches, pull the UP switch (+/OFF) toward you once with your fingers.2021 Mazda3 Engine and Transmission User Manual-83

  1. UP switch (+/OFF)

WARNING
Keep your hands on the steering wheel rim when using fingers on the steering shift switches: Putting your hands inside the rim of the steering wheel when using the steering shift switches is dangerous. If the driver’s air bag were to deploy in a collision, your hands could be impacted causing injury.

NOTE

  1. When driving slowly, the gears may not shift up.
  2. Do not drive the vehicle with the tachometer needle in the RED ZONE while in manual shift mode. In addition, manual shift mode switches to automatic shift mode while the accelerator pedal is completely depressed. This function is canceled while the DSC is turned off. However, if the vehicle is continuously driven at a high rpm, the gears may automatically shift up to protect the engine.
  3. The steering shift switch can be used temporarily even if the selector lever is in the D position while driving. In addition, it returns to automatic shift mode when the UP switch (+/OFF) is pulled rearward for a sufficient amount of time.

Manually Shifting Down
You can shift gears down by operating the selector lever or the steering shift switches*. M6 → M5 → M4 → M3 → M2→ M1

Using selector lever
To shift down to a lower gear, tap the selector lever forward once.2021 Mazda3 Engine and Transmission User Manual-84Using steering shift switch To shift down to a lower gear with the steering shift switches, pull the DOWN switch (–) toward you once with your fingers.2021 Mazda3 Engine and Transmission User Manual-84

  1. DOWN switch (–)

WARNING
Do not use engine braking on slippery road surfaces or at high speeds: Shifting down while driving on wet, snowy, or frozen roads, or while driving at high speeds causes sudden engine braking, which is dangerous. The sudden change in tire speed could cause the tires to skid. This could lead to loss of vehicle control and an accident. Keep your hands on the steering wheel rim when using fingers on the steering shift switches: Putting your hands inside the rim of the steering wheel when using the steering shift switches is dangerous. If the driver’s air bag were to deploy in a collision, your hands could be impacted causing injury.

NOTE 

  • When driving at high speeds, the gear may not shift down. During deceleration, the gear may automatically shift down depending on vehicle speed. When depressing the accelerator fully, the transmission will shift to a lower gear, depending on vehicle speed. However, the transmission does not kickdown while the DSC is turned off.

Second Gear Fixed Mode
When the selector lever is moved back + while the vehicle speed is about 10 km/h (6.2 mph) or less, the transmission is set in the second gear fixed mode. The gear is fixed in second while in this mode for easier acceleration from a stop and driving on slippery roads such as snow-covered roads. If the selector lever is moved back + or forward – while in the second gear fixed mode, the mode will be canceled.

Shift Gear (Shifting) Speed Limit
For each gear position while in the manual mode, the speed limit is set as follows: When the selector lever is operated within the range of the speed limit, the gear is shifted.

Shift up
The gear does not shift up while the vehicle speed is lower than the speed limit.

Shift down
The gear does not shift down while the vehicle speed exceeds the speed limit. If the vehicle speed exceeds the speed limit and the gear does not shift down, the gear position indication flashes 2 times to notify the driver that the gear cannot be shifted.

Kickdown
When the accelerator pedal is depressed fully while driving, the gear shifts down. However, the transmission does not kickdown while the DSC is turned off.

NOTE
The gear also shifts down using kickdown while in the second gear fixed mode.

Auto-shift down
The gear shifts down automatically depending on the vehicle speed during deceleration.

NOTE
If the vehicle comes to a stop while in the second gear fixed mode, the gear remains in second.

Recommendations for Shifting Upshifting
For normal acceleration and cruising, Mazda recommends these shift points:(U.S.A. and Canada)

Gear Vehicle speed*1
M1 to M2 24 km/h (15 mph)
M2 to M3 40 km/h (25 mph)
M3 to M4 65 km/h (40 mph)
M4 to M5 73 km/h (45 mph)
M5 to M6 81 km/h (50 mph)

Always observe local speed limit regulations.

Downshifting
When you must slow down in heavy traffic or on a steep upgrade, downshift before the engine starts to overwork. This gives better acceleration when you need more speed. On a steep downgrade, downshifting helps maintain safe speed and prolongs brake life.

Direct Mode

Direct Mode Direct mode can be used for temporarily switching gears by operating the steering shift switch while the vehicle is being driven with the selector lever in the D position. While in direct mode, the D and M indication illuminate and the gear position in use is illuminated.2021 Mazda3 Engine and Transmission User Manual-81

  1. Direct mode indication
  2. Gear position indication

Direct mode is canceled (released) under the following conditions.

  1. The UP switch (+/OFF) is pulled rearward for a certain amount of time or longer.
  2. The vehicle is driven for a certain amount of time or longer (time differs depending on the driving conditions while operating).
  3. The vehicle is stopped or moving at a slow speed.

NOTE Shifting up and down while in direct mode may not be possible depending on the vehicle speed. In addition, because direct mode is canceled (released) depending on the rate of acceleration or if the accelerator is fully depressed, use of the manual shift mode is recommended if you need to drive the vehicle in a particular gear for long periods.

Driving Tips

Driving Tips
WARNING
Do not let the vehicle move in a direction opposite to the direction selected by the selector lever: Do not let the vehicle move backward with the selector lever in a forward position, or do not let the vehicle move forward with the selector lever in the reverse position. Otherwise, the engine may stop, causing the loss of the power brake and power steering functions, and make it difficult to control the vehicle which could result in an accident.

Passing
For extra power when passing another vehicle or climbing steep grades, depress the accelerator fully. The transmission will shift to a lower gear, depending on vehicle speed.

NOTE

  • The accelerator pedal may initially feel heavy as it is being depressed, then feel lighter as it is depressed further. This change in pedal force aids the engine control system in determining how much the accelerator pedal has been depressed for performing kickdown, and functions to control whether or not kickdown should be performed. The manual shift mode does not switch to automatic shift mode while the DSC is turned off when the selector lever is in the M position. Shift the selector lever.

Climbing steep grades from a stop
To climb a steep grade from a stopped position:

  1. Depress the brake pedal.
  2. Shift to D or M1, depending on the load weight and grade steepness.
  3. Release the brake pedal while gradually accelerating.

Descending steep grades
When descending a steep grade, shift to lower gears, depending on load weight and grade steepness. Descend slowly, using the brakes only occasionally to prevent them from overheating.

Auto-light control
When the headlight switch is in the AUTO position and the ignition is switched ON, the light sensor senses the surrounding lightness or darkness and automatically turns the headlights and other exterior lights on or off.

CAUTION
Do not shade the light sensor by adhering a sticker or a label on the windshield. Otherwise the light sensor will not operate correctly.

2021 Mazda3 Engine and Transmission User Manual-92

  • The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and scrapers clear of the windshield when the wiper lever is in the AUTO position and the ignition is switched ON as fingers could be pinched or the wipers and wiper blades could be damaged when the wipers activate automatically. If you are going to clean the windshield, be sure the wipers are turned off completely when it is particularly tempting to leave the engine running. This is particularly important when clearing ice and snow.

NOTE

  • The headlights and other exterior lights may not turn off immediately even if the surrounding area becomes well-lit because the light sensor determines that it is night time if the surrounding area is continuously dark for several minutes such as inside long tunnels, traffic jams inside tunnels, or in indoor parking lots.
    If the headlight switch and the windshield wiper switch are in AUTO, and the wipers are operated at low or high speed by the auto wiper control for several seconds, bad weather conditions are determined and the headlights may be turned on.
    The sensitivity of the auto-light control may be changed.

Wipers and Washer

Windshield Wipers and Washer
The ignition must be switched ON to use the wipers.

WARNING
Use only windshield washer fluid or plain water in the reservoir:
Using radiator antifreeze as washer fluid is dangerous. If sprayed on the windshield, it will dirty the windshield, affect your visibility, and could result in an accident.

Only use windshield washer

fluid mixed with anti-freeze protection in freezing weather conditions:
Using windshield washer fluid without anti-freeze protection in freezing weather conditions is dangerous as it could freeze on the windshield and block your vision which could cause an accident. In addition, make sure the windshield is sufficiently warmed using the defroster before spraying the washer fluid.

CAUTION

  • When the wipers are not used during freezing temperatures or for a long time, the wiper rubber may adhere to the glass. If the wipers are operated while adhered to the glass, it could damage the wiper rubber and motor. If the wipers are operated while the glass is dry, the glass could be scratched and the wiper rubber damaged. When the glass is dry, spray washer fluid before operating the wipers.
  • If the amount of washer fluid spray is insufficient, do not use the washer switch. If the washer switch continues to be operated with no washer fluid being sprayed, it could lead to pump damage.

NOTE

If the windshield wipers are operated under cold weather conditions or during snowfall, they could stop due to accumulated snow on the windshield. If the windshield wipers stop due to accumulated snow on the windshield, park the vehicle in a safe place, turn the wiper switch off, and then remove the accumulated snow. If the wiper switch is turned to another position other than OFF, the wipers will operate. If the wipers do not operate even though the wiper switch is turned to a position other than OFF, consult an Authorized Mazda Dealer as soon as possible.

CAUTION

  • Do not shade the rain sensor by adhering a sticker or a label on the windshield. Otherwise the rain sensor will not operate correctly.2021 Mazda3 Engine and Transmission User Manual-104When the ignition is switched ON and the wiper lever is in the AUTO position, the windshield wipers may operate automatically in the following cases:
  • The area of the windshield above the rain sensor is touched or wiped with a cloth.
  • The windshield or the rain sensor area in the cabin is hit.

When the ignition is switched ON and the wiper lever is in the AUTO position, do not touch the windshield or the windshield wipers Otherwise, the windshield wipers will operate automatically which could catch your fingers or damage the windshield wipers. When removing ice or snow, or cleaning the windshield, always make sure the wiper lever is in the OFF position. NOTE

  • Switching the auto-wiper lever from the OFF to the AUTO position while driving activates the windshield wipers once, after which they operate according to the rainfall amount.
  • The auto-wiper control may not operate when the rain sensor temperature is about -10 °C (14 °F) or lower, or about 85 °C (185 °F) or higher.
  • If the windshield is coated with water repellent, the rain sensor may not be able to sense the amount of rainfall correctly and the auto-wiper control may not operate properly.
  • If dirt or foreign matter (such as ice or matter containing salt water) adheres to the windshield above the rain sensor, or if the windshield is iced, it could cause the wipers to move automatically. However, if the wipers cannot remove this ice, dirt or foreign matter, the auto-wiper control will stop operation. In this case, set the wiper lever to the low speed position or high speed position for manual operation, or remove the ice, dirt or foreign matter by hand to restore the auto-wiper operation.
  • If the auto-wiper lever is left in the AUTO position, the wipers could operate automatically from the effect of strong light sources, electromagnetic waves, or infrared light because the rain sensor uses an optical sensor. It is recommended that the auto-wiper lever be switched to the OFF position other than when driving the vehicle under rainy conditions.
  • If the headlight switch and the windshield wiper switch are in AUTO, and the wipers are operated at low or high speed by the auto wiper control for several seconds, bad weather conditions are determined and the headlights may be turned on. The auto-wiper control functions can be turned off. Refer to the Settings section in the Mazda Connect Owner’s Manual.

Manual Transmission

Manual Transmission Shift Pattern2021 Mazda3 Engine and Transmission User Manual-70

  1.  Neutral position
    The shift pattern of the transmission is conventional, as shown. Depress the clutch pedal all the way down while shifting; then release it slowly. Your vehicle is equipped with a device to prevent shifting to R (reverse) by mistake. Push the shift lever downward and shift to R.

2021 Mazda3 Engine and Transmission User Manual-71

WARNING

Do not use sudden engine braking on slippery road surfaces or at high speeds:
Shifting down while driving on wet, snowy, or frozen roads, or while driving at high speeds causes sudden engine braking, which is dangerous. The sudden change in tire speed could cause the tires to skid. This could lead to loss of vehicle control and an accident.

Always leave the shift lever in 1 or R position and set the parking brake when leaving the vehicle unattended:
Otherwise the vehicle could move and cause an accident.

CAUTION

  •  Keep your foot off the clutch pedal except when shifting gears. Also, do not use the clutch to hold the vehicle on an upgrade. Riding the clutch will cause needless clutch wear and damage.
  •  Do not apply any excessive lateral force to the shift lever when changing from 5th to 4th gear. This could lead to the accidental selection of 2nd gear, which could result in damage to the transmission.
  • Make sure the vehicle comes to a complete stop before shifting to R. Shifting to R while the vehicle is still moving may damage the transmission.

NOTE

  •  If shifting to R is difficult, shift back into neutral, release the clutch pedal, and try again.
    (With parking sensor system)
  • When the shift lever is shifted to the R position with the ignition switched ON, the parking sensor system is activated and a beep sound is heard. Refer to Parking Sensor System.

Gear Shift Indicator (GSI)
The GSI supports you to obtain optimum fuel economy and smooth driving. It displays the selected gear position in the instrument cluster as well as notifies the driver to change to the most suitable gear position corresponding to the actual driving condition.2021 Mazda3 Engine and Transmission User Manual-72

  1. Selected gear position
  2. Suitable gear position
Indication Condition
Numeral The selected gear position is displayed.
and numeral Shift up or down to the indicated gear position is recommended.

CAUTION
Do not rely solely on the shift-up/shift-down recommendations by indications. The actual driving situation might require shift operations different from indication. To avoid the risk of accidents, the road and traffic conditions have to be judged correctly by the driver before shifting.

NOTE
The GSI turns off when the following operations are performed.

  • The vehicle is stopped.
  • The vehicle is put in neutral.
  • The vehicle is driven in reverse.
  • The clutch is not fully engaged when accelerating from a stop.
  • The clutch pedal remains depressed for 2 seconds or longer while driving.

Recommendations for Shifting Upshifting
For normal acceleration, Mazda recommends these shift points:(U.S.A. and Canada)

Gear Vehicle speed
1 to 2 24 km/h (15 mph)
2 to 3 42 km/h (26 mph)
3 to 4 60 km/h (37 mph)
4 to 5 75 km/h (46 mph)
5 to 6 79 km/h (49 mph)

For cruising, Mazda recommends these shift points:
(U.S.A. and Canada)

Gear Vehicle speed
1 to 2 13 km/h (8 mph)
2 to 3 29 km/h (18 mph)
3 to 4 49 km/h (30 mph)
4 to 5 63 km/h (39 mph)
5 to 6 70 km/h (43 mph)

Downshifting
When you must slow down in heavy traffic or on a steep upgrade, downshift before the engine starts to overwork. This reduces the chance of stalling and gives better acceleration when you need more speed.

P (Park)
P locks the transmission and prevents the front wheels from rotating.

WARNING
Always set the selector lever to P position and set the parking brake: Only setting the selector lever to the P position without using the parking brake to hold the vehicle is dangerous. If P fails to hold, the vehicle could move and cause an accident.

CAUTION
Shifting into P, N or R while the vehicle is moving can damage your transmission. Shifting into a driving gear or reverse when the engine is running faster than idle can damage the transmission.

R (Reverse) In position R, the vehicle moves only backward. You must be at a complete stop before shifting to or from R, except under rare circumstances as explained in Rocking the Vehicle NOTE (With parking sensor system)In position R, the vehicle moves only backward. You must be at a complete stop before shifting to or from R, except under rare circumstances as explained in Rocking the Vehicle

NOTE
(With parking sensor system) When the selector lever is shifted to the R position with the ignition switched ON, the parking sensor system is activated and a beep sound is heard. Refer to Parking Sensor System

N (Neutral)
In N, the wheels and transmission are not locked. The vehicle will roll freely even on the slightest incline unless the parking brake or brakes are on.

WARNING
If the engine is running faster than idle, do not shift from N or P into a driving gear: It’s dangerous to shift from N or P into a driving gear when the engine is running faster than idle. If this is done, the vehicle could move suddenly, causing an accident or serious injury. Do not shift into N when driving the vehicle: Shifting into N while driving is dangerous. Engine braking cannot be applied when decelerating which could lead to an accident or serious injury.

CAUTION
Do not shift into N when driving the vehicle. Doing so can cause transmission damage.

NOTE
Apply the parking brake or depress the brake pedal before moving the selector lever from N position to prevent the vehicle from moving unexpectedly.

D (Drive)

Active Adaptive Shift (AAS) Active Adaptive Shift (AAS) automatically controls the transmission shift points to best suit the road conditions and driver input. This improves driving feel. The transmission may switch to AAS mode when driving up and down slopes, cornering, driving at high elevations, or depressing the accelerator pedal quickly while the selector lever is in the D position. Depending on the road and driving conditions/vehicle operations, gear

Manual Shift Mode

Manual Shift Mode The manual shift mode gives you the feel of driving a manual transmission vehicle by allowing you to operate the selector lever manually. This allows you to control engine rpm and torque to the drive wheels much like a manual transmission when more control is desired. To change to manual shift mode, shift the lever from D to M.2021 Mazda3 Engine and Transmission User Manual-80NOTE

  • Changing to manual shift mode while driving will not damage the transmission. If you change to manual shift mode when the vehicle is stopped, the gear will shift to M1. If you change to manual shift mode without depressing the accelerator pedal when driving in D range, 5th gear/6th gear, the gear will shift to M4/M5.

To return to automatic shift mode, shift the lever from M to D.

In manual shift mode, the “M” of the shift position indication in the instrument panel illuminates.

Gear position indication

The numeral for the selected gear illuminates.

NOTE

  • If the gears cannot be shifted down when driving at higher speeds, the gear position indication will flash twice to signal that the gears cannot be shifted down (to protect the transmission). If the automatic transmission fluid (ATF) temperature becomes too high, there is the possibility that the transmission will switch to automatic shift mode, canceling manual shift mode and turning off the gear position indication illumination. This is a normal function to protect the AT. After the ATF temperature has decreased, the gear position indication illumination turns back on and driving in manual shift mode is restored.

Manually Shifting Up
You can shift gears up by operating the selector lever or the steering shift switches*. M1 → M2 → M3 → M4 → M5 → M6

Using selector lever
To shift up to a higher gear, tap the selector lever back + once.2021 Mazda3 Engine and Transmission User Manual-81Using steering shift switch
To shift up to a higher gear with the steering shift switches, pull the UP switch (+/OFF) toward you once with your fingers.2021 Mazda3 Engine and Transmission User Manual-83

  1. UP switch (+/OFF)

WARNING
Keep your hands on the steering wheel rim when using fingers on the steering shift switches: Putting your hands inside the rim of the steering wheel when using the steering shift switches is dangerous. If the driver’s air bag were to deploy in a collision, your hands could be impacted causing injury.

NOTE

  1. When driving slowly, the gears may not shift up.
  2. Do not drive the vehicle with the tachometer needle in the RED ZONE while in manual shift mode. In addition, manual shift mode switches to automatic shift mode while the accelerator pedal is completely depressed. This function is canceled while the DSC is turned off. However, if the vehicle is continuously driven at a high rpm, the gears may automatically shift up to protect the engine.
  3. The steering shift switch can be used temporarily even if the selector lever is in the D position while driving. In addition, it returns to automatic shift mode when the UP switch (+/OFF) is pulled rearward for a sufficient amount of time.

Manually Shifting Down
You can shift gears down by operating the selector lever or the steering shift switches*. M6 → M5 → M4 → M3 → M2→ M1

Using selector lever
To shift down to a lower gear, tap the selector lever forward once.2021 Mazda3 Engine and Transmission User Manual-84Using steering shift switch To shift down to a lower gear with the steering shift switches, pull the DOWN switch (–) toward you once with your fingers.2021 Mazda3 Engine and Transmission User Manual-84

  1. DOWN switch (–)

WARNING
Do not use engine braking on slippery road surfaces or at high speeds: Shifting down while driving on wet, snowy, or frozen roads, or while driving at high speeds causes sudden engine braking, which is dangerous. The sudden change in tire speed could cause the tires to skid. This could lead to loss of vehicle control and an accident. Keep your hands on the steering wheel rim when using fingers on the steering shift switches: Putting your hands inside the rim of the steering wheel when using the steering shift switches is dangerous. If the driver’s air bag were to deploy in a collision, your hands could be impacted causing injury.

NOTE 

  • When driving at high speeds, the gear may not shift down. During deceleration, the gear may automatically shift down depending on vehicle speed. When depressing the accelerator fully, the transmission will shift to a lower gear, depending on vehicle speed. However, the transmission does not kickdown while the DSC is turned off.

Second Gear Fixed Mode
When the selector lever is moved back + while the vehicle speed is about 10 km/h (6.2 mph) or less, the transmission is set in the second gear fixed mode. The gear is fixed in second while in this mode for easier acceleration from a stop and driving on slippery roads such as snow-covered roads. If the selector lever is moved back + or forward – while in the second gear fixed mode, the mode will be canceled.

Shift Gear (Shifting) Speed Limit
For each gear position while in the manual mode, the speed limit is set as follows: When the selector lever is operated within the range of the speed limit, the gear is shifted.

Shift up
The gear does not shift up while the vehicle speed is lower than the speed limit.

Shift down
The gear does not shift down while the vehicle speed exceeds the speed limit. If the vehicle speed exceeds the speed limit and the gear does not shift down, the gear position indication flashes 2 times to notify the driver that the gear cannot be shifted.

Kickdown
When the accelerator pedal is depressed fully while driving, the gear shifts down. However, the transmission does not kickdown while the DSC is turned off.

NOTE
The gear also shifts down using kickdown while in the second gear fixed mode.

Auto-shift down
The gear shifts down automatically depending on the vehicle speed during deceleration.

NOTE
If the vehicle comes to a stop while in the second gear fixed mode, the gear remains in second.

Recommendations for Shifting Upshifting
For normal acceleration and cruising, Mazda recommends these shift points:(U.S.A. and Canada)

Gear Vehicle speed*1
M1 to M2 24 km/h (15 mph)
M2 to M3 40 km/h (25 mph)
M3 to M4 65 km/h (40 mph)
M4 to M5 73 km/h (45 mph)
M5 to M6 81 km/h (50 mph)

Always observe local speed limit regulations.

Downshifting
When you must slow down in heavy traffic or on a steep upgrade, downshift before the engine starts to overwork. This gives better acceleration when you need more speed. On a steep downgrade, downshifting helps maintain safe speed and prolongs brake life.

Direct Mode

Direct Mode Direct mode can be used for temporarily switching gears by operating the steering shift switch while the vehicle is being driven with the selector lever in the D position. While in direct mode, the D and M indication illuminate and the gear position in use is illuminated.2021 Mazda3 Engine and Transmission User Manual-81

  1. Direct mode indication
  2. Gear position indication

Direct mode is canceled (released) under the following conditions.

  1. The UP switch (+/OFF) is pulled rearward for a certain amount of time or longer.
  2. The vehicle is driven for a certain amount of time or longer (time differs depending on the driving conditions while operating).
  3. The vehicle is stopped or moving at a slow speed.

NOTE Shifting up and down while in direct mode may not be possible depending on the vehicle speed. In addition, because direct mode is canceled (released) depending on the rate of acceleration or if the accelerator is fully depressed, use of the manual shift mode is recommended if you need to drive the vehicle in a particular gear for long periods.

Driving Tips

Driving Tips
WARNING
Do not let the vehicle move in a direction opposite to the direction selected by the selector lever: Do not let the vehicle move backward with the selector lever in a forward position, or do not let the vehicle move forward with the selector lever in the reverse position. Otherwise, the engine may stop, causing the loss of the power brake and power steering functions, and make it difficult to control the vehicle which could result in an accident.

Passing
For extra power when passing another vehicle or climbing steep grades, depress the accelerator fully. The transmission will shift to a lower gear, depending on vehicle speed.

NOTE

  • The accelerator pedal may initially feel heavy as it is being depressed, then feel lighter as it is depressed further. This change in pedal force aids the engine control system in determining how much the accelerator pedal has been depressed for performing kickdown, and functions to control whether or not kickdown should be performed. The manual shift mode does not switch to automatic shift mode while the DSC is turned off when the selector lever is in the M position. Shift the selector lever.

Climbing steep grades from a stop
To climb a steep grade from a stopped position:

  1. Depress the brake pedal.
  2. Shift to D or M1, depending on the load weight and grade steepness.
  3. Release the brake pedal while gradually accelerating.

Descending steep grades
When descending a steep grade, shift to lower gears, depending on load weight and grade steepness. Descend slowly, using the brakes only occasionally to prevent them from overheating.

Auto-light control
When the headlight switch is in the AUTO position and the ignition is switched ON, the light sensor senses the surrounding lightness or darkness and automatically turns the headlights and other exterior lights on or off.

CAUTION
Do not shade the light sensor by adhering a sticker or a label on the windshield. Otherwise the light sensor will not operate correctly.

2021 Mazda3 Engine and Transmission User Manual-92

  • The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and scrapers clear of the windshield when the wiper lever is in the AUTO position and the ignition is switched ON as fingers could be pinched or the wipers and wiper blades could be damaged when the wipers activate automatically. If you are going to clean the windshield, be sure the wipers are turned off completely when it is particularly tempting to leave the engine running. This is particularly important when clearing ice and snow.

NOTE

  • The headlights and other exterior lights may not turn off immediately even if the surrounding area becomes well-lit because the light sensor determines that it is night time if the surrounding area is continuously dark for several minutes such as inside long tunnels, traffic jams inside tunnels, or in indoor parking lots.
    If the headlight switch and the windshield wiper switch are in AUTO, and the wipers are operated at low or high speed by the auto wiper control for several seconds, bad weather conditions are determined and the headlights may be turned on.

Wipers and Washer

Windshield Wipers and Washer
The ignition must be switched ON to use the wipers.

WARNING
Use only windshield washer fluid or plain water in the reservoir:
Using radiator antifreeze as washer fluid is dangerous. If sprayed on the windshield, it will dirty the windshield, affect your visibility, and could result in an accident.

Only use windshield washer

fluid mixed with anti-freeze protection in freezing weather conditions:
Using windshield washer fluid without anti-freeze protection in freezing weather conditions is dangerous as it could freeze on the windshield and block your vision which could cause an accident. In addition, make sure the windshield is sufficiently warmed using the defroster before spraying the washer fluid.

CAUTION

  • When the wipers are not used during freezing temperatures or for a long time, the wiper rubber may adhere to the glass. If the wipers are operated while adhered to the glass, it could damage the wiper rubber and motor. If the wipers are operated while the glass is dry, the glass could be scratched and the wiper rubber damaged. When the glass is dry, spray washer fluid before operating the wipers.
  • If the amount of washer fluid spray is insufficient, do not use the washer switch. If the washer switch continues to be operated with no washer fluid being sprayed, it could lead to pump damage.

NOTE

If the windshield wipers are operated under cold weather conditions or during snowfall, they could stop due to accumulated snow on the windshield. If the windshield wipers stop due to accumulated snow on the windshield, park the vehicle in a safe place, turn the wiper switch off, and then remove the accumulated snow. If the wiper switch is turned to another position other than OFF, the wipers will operate. If the wipers do not operate even though the wiper switch is turned to a position other than OFF, consult an Authorized Mazda Dealer as soon as possible.

When the ignition is switched ON and the wiper lever is in the AUTO position, do not touch the windshield or the windshield wipers Otherwise, the windshield wipers will operate automatically which could catch your fingers or damage the windshield wipers. When removing ice or snow, or cleaning the windshield, always make sure the wiper lever is in the OFF position. NOTE

  • Switching the auto-wiper lever from the OFF to the AUTO position while driving activates the windshield wipers once, after which they operate according to the rainfall amount.
  • The auto-wiper control may not operate when the rain sensor temperature is about -10 °C (14 °F) or lower, or about 85 °C (185 °F) or higher.
  • If the windshield is coated with water repellent, the rain sensor may not be able to sense the amount of rainfall correctly and the auto-wiper control may not operate properly.
  • If dirt or foreign matter (such as ice or matter containing salt water) adheres to the windshield above the rain sensor, or if the windshield is iced, it could cause the wipers to move automatically. However, if the wipers cannot remove this ice, dirt or foreign matter, the auto-wiper control will stop operation. In this case, set the wiper lever to the low speed position or high speed position for manual operation, or remove the ice, dirt or foreign matter by hand to restore the auto-wiper operation.
  • If the auto-wiper lever is left in the AUTO position, the wipers could operate automatically from the effect of strong light sources, electromagnetic waves, or infrared light because the rain sensor uses an optical sensor. It is recommended that the auto-wiper lever be switched to the OFF position other than when driving the vehicle under rainy conditions.
  • If the headlight switch and the windshield wiper switch are in AUTO, and the wipers are operated at low or high speed by the auto wiper control for several seconds, bad weather conditions are determined and the headlights may be turned on. The auto-wiper control functions can be turned off. Refer to the Settings section in the Mazda Connect Owner’s Manual.

Windshield Washer Pull the wiper lever toward you to spray washer fluid and operate the windshield wipers several times. The washer fluid is sprayed only while the windshield wipers move out of their stowed positions to the point where they start reversing back.

WARNING
Do not use the HomeLink system with any garage door opener that lacks the safety stop and reverse feature: Using the HomeLink system with any garage door opener that lacks the safety stop and reverse feature as required by federal safety standards is dangerous. (This includes garage doors manufactured before April 1, 1982.) Using these garage door openers can increase the risk of serious injury or death. For further information, contact HomeLink at www.homelink.com or www.youtube.com/HomeLinkGentex or an Authorized Mazda Dealer. Always check the areas surrounding garage doors and gates for people or obstructions before programming or during operation of the HomeLink system: Programming or operating the HomeLink system without verifying the safety of areas surrounding garage doors and gates is dangerous and could result in an unexpected accident and serious injury if someone were to be hit.

NOTE
The programming will not be erased even if the battery is disconnected.

Pre-programming the HomeLink System

NOTE
It is recommended that a new battery be placed in the hand-held transmitter of the device being programmed to HomeLink for quicker training and accurate transmission of the radio-frequency signal.

  • Verify that there is a remote control transmitter available for the device you would like to program.

Programming the HomeLink System
The HomeLink system provides 3 buttons which can be individually selected and programmed using the transmitters for current, on-market devices as follows:

  1. Press and release the HomeLink button you would like to program. The indicator light flashes slowly in amber when the button is pressed.2021 Mazda3 Engine and Transmission User Manual-117Indicator light
    1. HomeLink button
  2. Hold the hand-held transmitter 2.5 to 7.5 cm (1 to 3 in) away from the HomeLink button you would like to program while keeping the indicator light in view.
    NOTE
    Depending on the hand-held transmitter, it may be easier to do the programming by holding it 15 to 20 cm (6 to 7.8 in) away from the HomeLink button.
  3. Press the hand-held transmitter button continuously until the indicator light changes from amber (flashing) to green (on/flashing).
    NOTE
    Some gate operators and garage door openers may require you to replace this Programming Step 3 with procedures noted in the “Gate Operator/Canadian Programming” section.
  4. Press the HomeLink button again to check if the programming has been completed.
    •  If the indicator light remains on in green, the programming is complete and the device becomes operational.
    • If the indicator light flashes rapidly in green, firmly press and hold the Homelink button and release it after two seconds have passed. Repeat this process up to three times to complete the programming. The device becomes operational and programming is complete. If the device does not operate, go to the next step.
  5. At the garage door opener receiver (motor-head unit) in the garage, locate the “learn” or “smart” button. This can usually be found where the hanging antenna wire is attached to the motor-head unit.
  6. Firmly press and release the “learn” or “smart” button. (The name and color of the button may vary by manufacturer.)

NOTE
Complete the programming within 30 seconds. Return to the vehicle and firmly press and hold the Homelink button, and then release it after two seconds have passed. Repeat the “press/hold/release” sequence a second time, and, depending on the brand of the garage door opener (or other rolling code equipped device), repeat this sequence a third time to complete the programming process. Press the programmed HomeLink button and make sure that the HomeLink System operates. If the status indicator arrows are flashing, refer to Garage Door Two-Way Communication.2021 Mazda3 Engine and Transmission User Manual-118

NOTE
To program the remaining two HomeLink buttons, go back to Step 1 of Programming the HomeLink System and repeat the procedure. For questions or comments, please contact HomeLink at www.homelink.com or www.youtube.com/HomeLinkGentex, or the HomeLink toll-free hotline at 1-800-355-3515 (for calls placed outside of the USA, Canada, and Puerto Rico, international rates will apply and may differ based on landline or mobile phone).

Gate operator/Canadian Programming
Canadian radio-frequency laws require transmitter signals to “time-out” (or quit) after several seconds of transmission which may not be long enough for HomeLink to pick up the signal during programming. Similar to this Canadian law, some U.S. gate operators are designed to “time-out” in the same manner. If you live in Canada or are having difficulties programming a gate operator by using the programming procedures (regardless of where you live), replace Step 3 of Programming the HomeLink System with the following:

NOTE
If programming a garage door opener or gate operator, it is advised to unplug the device during the “cycling” process to prevent possible overheating. While the indicator light is flashing in amber, press the button on the hand-held transmitter for 2 seconds and release it repeatedly until the indicator light changes from amber to green. Go back to Step 4 of Programming the HomeLink System to complete the procedure.

Operating the HomeLink System
Press the programmed HomeLink button to operate a programmed device.

Reprogramming the HomeLink system
To program a device to HomeLink using a HomeLink button previously trained, follow these steps:

  1. Press and hold the desired HomeLink button. DO NOT release the button.
  2. After 20 seconds, the indicator light flashes in amber. After the indicator light flashes, release the HomeLink button.
  3. Go back to Step 2 of Programming the HomeLink System to complete the procedure.

NOTE
If the programming has not been completed, the system returns to the previous programming.

Erasing Programmed HomeLink Buttons

NOTE

  • All of the programmed HomeLink buttons are reset. Individual buttons cannot be reset, however, individual buttons can be reprogrammed. For individual button reprogramming, refer to Reprogramming the HomeLink System . Verify that the programming has been erased if you resell the vehicle.
  1. Press the two outer HomeLink buttons continuously at the same time until the indicator light flashes.

Garage Door Two-Way Communication
The garage door two-way communication is a function that communicates with the garage door opener and indicates whether the garages door is open or closed using the indicator lights in the rear view mirror. It can indicate the status of the garage door within a range up-to 250 m (820 ft).

NOTE
The communication range may shorten depending on obstructions.

Programming two-way communication
Within five seconds after programming a new HomeLink button, both of the garage door status indicator lights will flash rapidly in green indicating that the garage door two-way communication has been established. If the garage door status indicator lights flash, the two-way communication programming is complete. If the garage door status indicator lights do not flash, the two-way communication programming is not completed. For additional HomeLink information and programming videos, refer to the following Websites:
