2020 Mazda3 Cruise Control User Manual

Introduction

The 2020 Mazda3 is a well-liked compact car that is renowned for its chic styling, agile handling, and cutting-edge technology. The Mazda3’s cruise control system, which was created to increase comfort and convenience on long rides, is one of its notable features. The 2020 Mazda3’s cruise control technology enables users to select a preferred speed for the car, which the system will then maintain automatically. This feature makes highway driving much easier because it frees the driver from frequent speed monitoring and adjustment. To improve the use and adaptability of the cruise control system, Mazda has incorporated smart technology. In order to maintain a safe following distance, the Mazda3 uses radar and video sensors to measure the distance to the car in front. Mazda Radar Cruise Control (MRCC) with Stop & Go capabilities is the name of this adaptive cruise control feature.

The Mazda3’s cruise control technology not only keeps the vehicle moving at a predetermined speed, but it can also lessen driver fatigue by automatically changing the speed to keep up with traffic. The Mazda3 will accelerate less if the car in front of it slows down, and once the road is free, it will resume its pre-set speed.

Cruise Control

Cruise Control
With cruise control, you can set and automatically maintain any speed of more than about 30 km/h (19 mph).

WARNING
Do not use the cruise control under the following conditions:
Using the cruise control under the following conditions is dangerous and could result in loss of vehicle control.

• Hilly terrain Steep inclines Heavy or unsteady traffic Slippery or winding roads Similar restrictions that require inconsistent speed The vehicle speed may exceed the set speed during sudden acceleration or on steep down slopes. In this case, depress the brake pedal to adjust the vehicle speed.

3. Adjust the system to the desired vehicle speed using the accelerator pedal. Press the RES switch up (SET+) or down (SET-) to start cruise control. The cruise control indication (green) in the instrument cluster turns on at the same time. Quickly release the switch when the cruise control indication (green) turns on.

NOTE

• If the RES switch is operated up (SET+) or down (SET-) while the vehicle speed is between 25 and 30 km/h (16 to 19 mph), the set speed is set to 30 km/h (19 mph). The cruise control speed setting cannot be performed under the following conditions: Any of the doors is opened. The driver’s seat belt is unfastened. The brake pedal is depressed.
• The parking brake is applied.
• (Automatic transmission) The selector lever is in the P, N, or R position. (Manual transmission) The shift lever is in the neutral position.
• On a steep grade, the vehicle may momentarily slow down while ascending or speed up while descending.
• The cruise control will cancel if the vehicle speed decreases below 20 km/h (12 mph) when the cruise control is activated, such as when climbing a steep grade.

The vehicle speed preset using the cruise control is displayed in the instrument cluster and the active driving display (vehicles with active driving display).
Instrument cluster (Basic display)Instrument cluster (i-ACTIVSENSE display)Active driving displayChanging the Set Vehicle Speed
Follow either of these procedures

To increase/decrease speed using cruise control switch
When the RES switch is pressed up (SET+), the vehicle accelerates and when the RES switch is pressed down (SET-), it decelerates. Press and release immediately: 1 km/h (1 mph) Press and hold: 10 km/h (5 mph)

NOTE
Even after releasing the RES switch, the cruise control accelerates/decelerates continuously until the set speed displayed in the instrument cluster and on the active driving display is reached. If you want to stop accelerating/decelerating, change the set speed or cancel the system (such as by depressing the brake pedal).

To increase speed using accelerator pedal
Depress the accelerator pedal and press the RES switch up (SET+) or down (SET-) at the desired speed. If the switch is not operated, the system returns to the set speed after you release your foot from the accelerator pedal.

NOTE
Accelerate if you want to speed up temporarily when the cruise control is on. Greater speed will not interfere with or change the set speed. Take your foot off the accelerator to return to the set speed. To Resume Cruising Speed at More Than 30 km/h (19 mph) If the cruise control system is temporarily canceled (such as by applying the brake pedal) and the system is still activated, the most recent set speed will automatically resume when the RES switch is pressed. If vehicle speed is below 30 km/h (19 mph), increase the vehicle speed up to 30 km/h (19 mph) or more and press the RES switch.

To Temporarily Cancel
To temporarily cancel the system, use one of these methods:

• Slightly depress the brake pedal. Press the CANCEL switch.
• (Manual transmission) Depress the clutch pedal.

If the RES switch is pressed when the vehicle speed is 30 km/h (19 mph) or higher, the system reverts to the previously set speed.

NOTE

• If any of the following conditions occur, the cruise control system is temporarily canceled. Even when the brake pedal is slightly depressed. The DSC is operating. There is a problem in the system. Any of the doors is opened. The driver’s seat belt is unfastened. The parking brake is applied. (Automatic transmission) The selector lever is in the P, N, or R position.
•  
• (Manual transmission)
  The shift lever is in the neutral position.
• When the cruise control system is temporarily canceled by even one of the applicable cancel conditions, the speed cannot be re-set.
•  
• (Automatic transmission)
• The cruise control cannot be canceled while driving in manual mode (selector lever shifted from D to M position). Therefore, engine braking will not be applied even if the transmission is shifted down to a lower gear. If deceleration is required, lower the set speed or depress the brake pedal.

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 center 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.

Rear View Monitor

The rear view monitor provides visual images of the rear of the vehicle when reversing.
WARNING

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.

1. Front ultrasonic sensor*
2. Front corner ultrasonic sensor*
3. Rear ultrasonic sensor
4. Rear corner ultrasonic sensor
5. Rear side ultrasonic sensor*

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).

Parking Sensor OFF Switch
When the switch is pressed, the parking sensor is stopped and the indicator light turns on. If the switch is pressed again, the parking sensor becomes operational and the indicator light turns off.

1.  Indicator light

NOTE

• (Automatic vehicle)
  The detection indicator and buzzer of the front ultrasonic sensors/front corner ultrasonic sensors do not operate when the selector lever is in the P position.
• The detection indicator and buzzer sound do not activate when the parking brake is applied.

Obstruction Detection Indication
The position of a sensor which has detected an obstruction is indicated. The gauge illuminates in different areas depending on the distance to an obstruction detected by the sensor. As the vehicle approaches closer to an obstruction, the zone in the gauge closer to the vehicle illuminates. Without 360°view monitor.

NOTE
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. (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 was detected. However, while the 360°view monitor is displayed, it continues to display no matter if an obstruction is detected or not.

System problem notification
The indication displays if the system has a malfunction.

Without 360°view monitorWith 360°view monitor Check the reason for the indication displaying on the center display or multi-information display. Refer to If a Warning Light Turns On or Flashes.

Parking Sensor Warning Beep
Informs the driver of the approximate distance from the vehicle to the obstruction using warning beeps depending on the distance. If multiple obstructions are detected at the same time, warning beeps are activated according to the distance to the nearest obstruction. The warning beeps are activated as follows while the system is operating. However, the warning beeps are not activated while the seat belt reminder is operating.

Farthest distance	Approx. 100―60.0 cm (39.3―23.6 in)	Approx. 150―60.0 cm (59.0―23.6 in)	Slow intermittent sound
Far distance	Approx. 60.0―45.0 cm (23.6―17.7 in)	Approx. 60.0―45.0 cm (23.6―17.7 in)	Medium intermit- tent sound
Middle distance	Approx. 45.0―35.0 cm (17.7―13.7 in)	Approx. 45.0―35.0 cm (17.7―13.7 in)	Fast intermittent sound

Distance Detection area	Distance between vehicle and obstruction	Beeper sound*1
	Front corner ultrasonic sensor/Rear corner, Rear side ultrasonic sensor
Close distance	Within approx. 25 cm (9.8 in)	Continuous sound

• 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 close side, the warning beeps resumes. (If the detection area changes to the far side, the warning beeps remain off)
• The sound volume (each of front and rear) can be changed. Refer to the Settings section in the Mazda Connect Owner’s Manual.
