To Deactivate
Press the cruise switch again.

Tire Pressure Monitoring System (TPMS)

Tire Pressure Monitoring System (TPMS)
The TPMS monitors the air pressure of each tire and if it decreases below the specified value, the system notifies the driver by turning on the TPMS warning light in the instrument cluster and indicating a message on the multi-information display. For the TPMS, the air pressure data sent from the tire pressure sensors installed on each wheel via radio signal is received by the receiver unit in the vehicle to monitor the tire pressures. Tire pressure sensors In addition, the current tire pressures can be checked using the centre display. Refer to the Vehicle Status Monitor section in the Mazda Connect Owner’s Manual. NOTE

• When the ambient temperature is low, the tire temperatures also decrease. If the tire temperatures decrease, the air pressure in the tires will also decrease which could turn on the TPMS warning light.
• Before driving, visually inspect the tires for abnormalities. Additionally, inspect the tire pressures monthly. A digital-type air pressure gauge is recommended for inspecting the tire pressures.

The TPMS is not a substitute for your own periodic inspection of the tires. Always inspect the tires yourself periodically.

CAUTION

• Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.
• Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.
• To avoid false readings, the system samples for a little while before indicating a problem. As a result it will not instantaneously register a rapid tire deflation or blow out.

If there is a problem with the Tire Pressure Monitoring System (TPMS)
If the TPMS warning light flashes, there may be a problem with the system. Consult an Authorized Mazda Dealer to have the system inspected. Refer to Tire Pressure Monitoring System (TPMS) Warning Indication/Warning Light (Flashing) In the following cases, the system cannot recognize the tire pressures correctly and the TPMS warning light may flash.

• There is equipment or a device nearby emitting radio signals the same as a tire pressure sensor. A metallic object such as a non-genuine electronic device is installed near the center of the dashboard (obstructs the radio signals from the tire pressure sensors to the receiver). A device such as one of the following is used in the cabin. Electronic devices such as a computer. Converter devices such as a DC-AC converter. There is a large accumulation of snow or ice around the vehicle tires. The battery in a tire pressure sensor is dead. A wheel not equipped with a tire pressure sensor is used. Tires employing steel in the sidewall of the tire are installed. Tire chains are used.

When a tire pressure decreases
If the TPMS warning light turns on, a tire pressure may be low. Inspect the tire pressures and adjust them to the correct inflation pressure. Refer to Tire Pressure Monitoring System (TPMS) Warning Indication/Warning Light (Turns on)

Tires and Wheels
CAUTION
When inspecting/adjusting the tire pressures, do not apply excessive force to the air valve of the tire pressure sensor. Otherwise, the tire pressure sensor could be damaged. When changing tires and wheels When changing the tires or wheels (such as installing winter tires), it will be necessary to register the ID signal code of the tire pressure sensor to the TPMS. Have an Authorized Mazda Dealer do the registration or register the ID signal codes of the tire pressure sensors using the following procedure.

NOTE
The tire pressure sensors on each wheel have a unique ID signal code. For the TPMS to operate correctly, the ID signal codes of the tire pressure sensors need to be registered to the system.

1. Wait more than 19 minutes after changing a tire or wheel.
2. After more than 19 minutes have passed, drive the vehicle at a speed of about 25 km/h (16 mph) or faster for 3 minutes or longer. While driving, the ID signal codes of the tire pressure sensors are automatically registered.

NOTE
If you drive the vehicle within 19 minutes of changing a tire or wheel, the TPMS warning light will flash because the ID signal codes for the tire pressure sensors were not registered. In this case, stop the vehicle and register the ID signal codes of the tire pressure sensors following the procedure. When replacing tires and wheels.

CAUTION
When replacing the tires and wheels, consult an Authorized Mazda Dealer Otherwise, the tire pressure sensors could be damaged when replacing them. Do not install non-genuine wheels. If wheels other than genuine ones are installed, it may not be possible to install the tire pressure sensors. When replacing a tire or wheel, always install the tire pressure sensor. The following combinations of tires, wheels, or tires and wheels are possible.

• The tire pressure sensor from the old wheel is removed and it is installed to the new wheel. Only a tire is replaced without replacing the tire pressure sensor and wheel. A new tire pressure sensor is installed to a new wheel.

NOTE
 When installing a new tire pressure sensor, the ID signal code for the tire pressure sensor needs to be registered. For details on purchasing a tire pressure sensor and registering the ID signal of the tire pressure sensor, consult an Authorized Mazda Dealer.

• Projected vehicle path (yellow) These lines are displayed as a reference for the projected path of the vehicle. The lines displaying the projected vehicle path change after you turn the steering wheel.
• Extended vehicle width lines (blue) These lines indicate the vehicle’s extended width. These lines are not displayed when the vehicle’s wheels are in the straight-ahead position.
• Distance guide lines (red)
• These lines indicate the approximate distance to a point measured from the vehicle’s rear (from the end of the bumper). The blue line indicates the point about 0.5 m (19 in) from the rear bumper. The red and yellow lines, which change position after you turn the steering wheel, indicate the points about 0.5 m (19 in) for the red line and 1.0 m (39 in) and 2.0 m (78 in) for the yellow lines from the rear bumper (at the center point of each of the lines). A degree of error occurs when the wheels are not in the straight-ahead position. In the above illustration, the right side of the vehicle is in a position closer to the actual distance displayed by the distance guide lines (red: about 0.5 m (19 in) point, yellow: about 1.0 m (39 in), and yellow: about 2.0 m (78 in) point behind the rear bumper), whereas the left side is in a position farther away.

CAUTION
The indicated position of the guide lines on the display changes depending on the vehicle conditions (such as the number of occupants/cargo load) and the road conditions (such as a steep gradient to the rear of the vehicle). Always check the area to the vehicle’s rear and the surrounding area directly with your eyes while backing up.

Fixed assist lines display type
Guide lines which indicate the width of the vehicle are displayed on the screen as a reference to the approximate width of the vehicle in comparison to the width of the parking space you are about to back into. Use this display view for parking your vehicle in a parking space or garage.

• Vehicle width guide lines Guide lines serve as a reference to the approximate width of the vehicle.
• Distance guide lines These guide lines indicate the approximate distance to a point measured from the vehicle’s rear (from the end of the bumper). The red line indicates the point about 0.5 m (19 in) from the rear bumper.
• The yellow lines indicate the points about 1.0 m (39 in) and 2.0 m (78 in) from the rear bumper.

CAUTION
The guide lines on the screen are fixed lines. They are not synced to the driver’s turning of the steering wheel. Always be careful and check the area to the vehicle’s rear and the surrounding area directly with your eyes while backing up.

Rear View Monitor Operation
The operation of the rear view monitor when reversing the vehicle varies depending on the traffic, road, and vehicle conditions. The amount of steering and the timing also varies depending on conditions, so confirm the surrounding conditions directly with your eyes and steer the vehicle in accordance with the conditions. Be well aware of the above cautions prior to using the rear view monitor. Predicted vehicle path assist lines display type

NOTE
The following shows an example of vehicle parking in which the steering wheel is turned to the right when backing up the vehicle. The operation is reversed when backing up the vehicle from the opposite direction.

1. Shift the shift lever (manual transmission) or the selector lever (automatic transmission) to reverse (R) position to switch the display to the rear view monitor display.
2. Before backing the vehicle into the parking space, turn the steering wheel while referring to the projected vehicle path display so that the vehicle enters the center of the parking space.
3.  (Display condition)
4. (Vehicle condition)
5. Continue to adjust the steering wheel until the vehicle width guide lines are parallel to the left and right sides of the parking space.
6. Once they are parallel, straighten the wheels and back your vehicle slowly into the parking space. Continue checking the vehicle’s surroundings and then stop the vehicle in the best possible position. (If the parking space has division lines, check whether the vehicle width guide lines are parallel to them.)

1.  (Display condition)
2.  (Vehicle condition)
3. When the shift lever (manual transmission) or the selector lever (automatic transmission) is shifted from reverse (R) position to another shift lever (manual transmission) or the selector lever (automatic transmission) position, the screen returns to the previous display.

NOTE Because there may be a difference between the displayed image, such as indicated below, and the actual conditions when parking, always verify the safety at the rear of the vehicle and the surrounding area directly with your eyes.

• In the image of the parking space (or garage) displayed on the screen, the back end and distance guide lines may appear aligned in the monitor, but they may not actually be aligned on the ground.

When parking in a space with a division line on only one side of the parking space, the division line and the vehicle width guide line appear aligned in the monitor, but they may not actually be aligned on the ground. Fixed assist lines display type

• NOTE
  Images displayed on the monitor from the rear view parking camera are reversed images (mirror images).

1.  Shift the shift lever (manual transmission) or the selector lever (automatic transmission) to reverse (R) position to switch the display to the rear view monitor display.
2.  Confirming the surrounding conditions, reverse the vehicle.
3. After your vehicle begins entering the parking space, continue backing up slowly so that the distance between the vehicle width lines and the sides of the parking space on the left and right are roughly equal.
4. (Display condition)
5.  (Vehicle condition)
6. Continue to adjust the steering wheel until the vehicle width guide lines are parallel to the left and right sides of the parking space.
7. Once they are parallel, straighten the wheels and back your vehicle slowly into the parking space. Continue checking the vehicle’s surroundings and then stop the vehicle in the best possible position. (If the parking space has division lines, check whether the vehicle width guide lines are parallel to them.)

10. When the shift lever (manual transmission) or the selector lever (automatic transmission) is shifted from reverse (R) position to another shift lever (manual transmission) or the selector lever (automatic transmission) position, the screen returns to the previous display.

NOTE
Because there may be a difference between the displayed image, such as indicated below, and the actual conditions when parking, always verify the safety at the rear of the vehicle and the surrounding area directly with your eyes.

• In the image of the parking space (or garage) displayed on the screen, the back end and distance guide lines may appear aligned in the monitor, but they may not actually be aligned on the ground.
• When parking in a space with a division line on only one side of the parking space, the division line and the vehicle width guide line appear aligned in the monitor, but they may not actually be aligned on the ground. Variance Between Actual Road Conditions and Displayed Image
• Some variance occurs between the actual road and the displayed road. Such variance in distance perspective could lead to an accident. Note the following conditions that may cause a variance in distance perspective. When the vehicle is tilted due to the weight of passengers and load When the vehicle rear is lowered, the object displayed on the screen appears farther than the actual distance.

Three-dimensional object on vehicle rear
Because the distance guide lines are displayed based on a flat surface, the distance to the three-dimensional object displayed on the screen is different from the actual distance.

1.  (Screen display)
2.  (Actual condition)
3.  Sensed distance on screen A>B>C
4. Actual distance B>C=A

(Predicted vehicle path assist lines display type)
When reversing near a three-dimensional object When reversing near an overhanging object, the vehicle may hit the object even if the anticipated course line does not contact the object on the screen. The position of the object displayed on the screen is different from the actual position because the anticipated course lines on the screen are displayed based on a horizontal road surface. When backing up near an overhanging object, confirm the rear and surrounding conditions directly with your eyes.

Parking Sensor System

The parking sensors use ultrasonic sensors which detect obstructions around the vehicle when the vehicle is driven at low speeds, such as during garage or parallel parking, and a buzzer sound and detection indicator notify the driver of the approximate distance from the vehicle to the surrounding obstruction.

WARNING
Do not rely completely on the parking sensor system and be sure to confirm the safety around your vehicle visually when driving: This system can assist the driver in operating the vehicle in the forward and backward directions while parking. The detection ranges of the sensors are limited, therefore, driving the vehicle while relying only on the system may cause an accident. Always confirm the safety around your vehicle visually when driving.

CAUTION

1. Do not install any accessories within the detection ranges of the sensors. It may affect the system operation.
2. Depending on the type of obstruction and the surrounding conditions, the detection range of a sensor may narrow, or the sensors may not be able to detect obstructions.
3. When washing the vehicle, do not spray highly pressurized water against the sensor area, or rub it strongly. Otherwise, it may not be able to detect obstructions correctly and the system may not operate normally.

NOTE

1. When the ignition is switched OFF, the system status before it was turned off is maintained. For example, if the ignition is switched OFF while the parking sensor is activated, the system will be activated when the ignition is switched ON the next time.
2. The system may not operate normally under the following conditions:
   1. Mud, ice, or snow is adhering to the sensor area (Returns to normal operation when removed).
   2. The sensor area is frozen (Returns to normal operation when the ice is thawed).
   3. The sensor is covered by a hand.
   4. The sensor is excessively shocked.
   5. The vehicle is excessively tilted.
   6. Under extremely hot or cold weather conditions.
   7. The vehicle is driven on bumps, inclines, gravel, grating, or grass-covered roads.
   8. Anything which generates ultrasonic waves such as another vehicle’s horn, the engine sound of a motorcycle, the air brake sound of a large-sized vehicle, or another vehicle’s sensors approaches the vehicle.
   9. The vehicle is driven in heavy rain or in road conditions causing water splash.
   10. A commercially-available fender pole or an antenna for a radio transmitter is installed to the vehicle.
   11. The vehicle is moving towards a tall or square curbstone or a steep grade.
   12. An obstruction is too close to the sensor.
   13. The vehicle is moving towards an uneven wall or stairs.
   14. There are multiple obstructions.
   15. The vehicle is driven in a place with low ceilings.
3. Obstructions under the bumper cannot be detected. Obstructions that are lower than the sensor or thin may not be detected even though they were detected once.
4. The following types of obstructions may not be detected:
   1. Thin objects such as wire, rope or poles
   2. Things that absorb sonic waves easily such as cotton or snow
   3. Angular shaped objects
   4. Very tall objects, and those which are wide at the top
   5. Small, short objects
5. Always have the system inspected at an Authorized Mazda Dealer if any shock is applied to the bumpers, even in a minor accident. If the sensors are deviated, they cannot detect obstructions.
6. The system may malfunction if a sound is not activated or the detection indication is not displayed even when the parking sensor OFF switch is pressed and the parking sensor is operable. Have your vehicle inspected by an Authorized Mazda Dealer.
7. The system may malfunction if the indicator light does not turn on even when the parking sensor OFF switch is turned on. Have your vehicle inspected by an Authorized Mazda Dealer.
8. The system may malfunction if a message indicating a system malfunction is displayed. Have your vehicle inspected by an Authorized Mazda Dealer.
9. A message may be displayed even when the ambient temperature is extremely cold, or mud, ice, or snow adheres to the sensor area. Remove any foreign matter from the sensor area.
10. When installing a trailer hitch, consult an Authorized Mazda Dealer.
11. If a Mazda genuine trailer hitch is used, the rear side of the parking sensor system is automatically turned off.

NOTE

1. The detection indicator can be switched between display and non-display and the buzzer volume can be changed. Refer to the Settings section in the Mazda Connect Owner’s Manual.
2. (Vehicles with 360° View Monitor) When the detection indicator is set to “Display”, even with the 360° view monitor not displayed, if a front sensor or a front corner sensor detects an obstruction, the 360° view monitor switches automatically to display. When an obstruction is no longer detected, the display switches to the display before the obstruction is detected. However, while the 360° view monitor is displayed, it continues to display no matter if an obstruction is detected or not.
3. If an obstruction in the same area excluding the close area is detected continuously for 6 seconds or longer, only the warning beeps stop activating. (Detection is indicated) If the detection area changes to the closed side, the warning beeps resume. (If the detection area changes to the far side, the warning beeps remain off)
