Switching to high beams
Turn the headlight switch to the position.
The HBC indicator light (green) turns off and the is illuminated.
Blind Spot Monitoring (BSM) Warning Indicator Light/Display Indicator/Blind Spot Monitoring (BSM) Warning Beep
The BSM or Rear Cross Traffic Alert (RCTA) system notifies the driver of the presence of vehicles in adjacent lanes or at the rear of the vehicle using the BSM warning indicator light, the warning sound and the display indicator (vehicles with instrument cluster (Type A/B) and active driving display) (BSM) while the systems are operational.
BSM warning indicator lights
The BSM warning indicator lights are equipped on the left and right door mirrors. The warning indicator lights turn on when a vehicle approaching from the rear in an adjacent lane is detected.

When the ignition is switched ON, the warning indicator light turns on momentarily and then turns off after a few seconds.
Forward driving (BSM operation)
The BSM detects vehicles approaching from the rear and turns on the BSM warning indicator lights equipped on the door mirrors according to the conditions. Additionally, while a BSM warning indicator light is illuminated, if the turn signal lever is operated to signal a turn in the direction in which the BSM warning indicator light is illuminated, the BSM warning indicator light flashes.
Reverse driving (Rear Cross Traffic Alert (RCTA) system operation)
The Rear Cross Traffic Alert (RCTA) system detects a vehicle approaching from the rear of the vehicle and flashes the BSM warning indicator lights.
Function for cancelling illumination dimmer
If the BSM warning indicator lights turn on when the parking lights are turned on, the brightness of the BSM warning indicator lights is dimmed.
If the BSM warning indicator lights are difficult to see due to glare from surrounding brightness when traveling on snow-covered roads or under foggy conditions, press the dimmer cancellation button to cancel the dimmer and increase the brightness of BSM warning indicator lights when they turn on.
Refer to Dashboard Illumination (Search), (Search), (Search).
Display indicator (Vehicles with multi-information display and active driving display)
The detected approaching vehicle and warning are displayed in the multi-information display and active driving display when the vehicle is moving forward (BSM operational).

The detected direction is displayed with a detection indicator (white) when an approaching vehicle is detected. In addition, if the turn signal lever is operated to signal a lane change while the vehicle is detected, the display changes the color (amber) of the warning indicator.
BSM warning beep
The BSM warning beep is activated simultaneously with the flashing of a BSM warning indicator light.

Cruise Control Function
While this function is operating, the headway control operation is canceled and only the cruise control function operates.
The vehicle speed can be set more than about 25 km/h (16 mph).
Use the cruise control function on expressways and other highways which do not require a lot of repeated acceleration and deceleration.
Do not use the cruise control function in the following locations:
Otherwise, it could lead to an accident.
-
Roads with sharp curves and where vehicle traffic is heavy and there is insufficient space between vehicles. (Driving under these conditions using the cruise control function is not possible)
-
Steep down slopes (Set speed may be exceeded because sufficient engine braking cannot be applied)
-
Slippery roads such as ice or snow-bound roads (Tires could spin causing you to lose vehicle control)
Always drive carefully:
The warnings and brake control will not operate after the headway control function is canceled and the system is switched to only the cruise control function. Depress the brake pedal to decelerate according to the surrounding conditions while keeping a safer distance from the vehicle ahead and always driving carefully.
Switching to cruise control function
Steering wheel (Type A)
When the MODE switch is pressed until the system switches to the cruise main indication (white) while the MRCC with Stop & Go function system is turned on, the system switches to the cruise control function.
Steering wheel (Type B)
Use Mazda Connect to switch to the cruise control function.
Refer to the Settings section in the Mazda Connect Owner's Manual.
When the system switches to the cruise control function, the indicator and multi-information display notify the driver as follows:
-
The MRCC with Stop & Go function set indication (green) or the MRCC with Stop & Go function main indication (white) is turned off, and the cruise main indication (white) is turned on.
-
A message is displayed in the multi-information display.
Always turn off the cruise control function when it is not in use:
Leaving the cruise control function turned on when it is not in use is dangerous as it could operate unexpectedly, resulting in an accident.
How to set the speed
Adjust the system to the desired vehicle speed using the accelerator pedal.
When the SET or SET
switch is pressed, the cruise set indication (green) is turned on and cruise control begins.
-
The system may not be able to maintain the set speed constantly depending on driving conditions such as steep up or down slopes.
-
The speed will continue increasing while the SET
switch is pressed and held. The speed will continue decreasing while the SET
switch is pressed and held.
How to increase the set speed
The set speed can be increased using the following operations:
To increase speed using the SET switch
Press and hold the SET switch and release the switch at the desired speed.
The set speed can be adjusted incrementally (1 km/h (1 mph) increments) by pressing the switch and releasing it immediately. For example, if the switch is pressed 4 times, the set speed increases by about 4 km/h (4 mph).
To increase speed using accelerator pedal
Depress the accelerator pedal and press the SET or SET
switch 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.
How to Decrease the Set Speed
Press the SET switch continuously and release the switch at the desired speed.
The set speed can be adjusted incrementally (1 km/h (1 mph) increments) by pressing the switch and releasing it immediately. For example, if the switch is pressed 4 times, the set vehicle speed decreases by about 4 km/h (4 mph).
Canceling the function
When the cruise control function is canceled and the RES switch is pressed while the vehicle speed is 25 km/h (16 mph) or faster, the speed returns to the original set speed.
Canceling using CANCEL switch
When the CANCEL switch is pressed once, the cruise control function is cancelled.
Automatically cancel
The cruise control function is canceled automatically in the following cases.
-
The brake pedal is depressed.
-
The parking brake is applied.
-
The selector lever is shifted to P or N position.
-
If the vehicle speed decreases by about 15 km/h (9.4 mph) or more than the set speed, the cruise control function may be canceled.
-
When the vehicle speed is less than 21 km/h (13 mph), the cruise control function is canceled. In this case, the vehicle speed will not return to the original set speed even if the vehicle is accelerated to 25 km/h (16 mph) or higher and the RES switch is pressed. Reset the cruise control function.
Traffic Jam Assist (TJA) (Some Models)
The TJA is a system which consists of a headway control function and a steering assist function for reducing driver fatigue during traffic jams when driving on expressways or highways.
This system performs headway control to maintain a constant distance between your vehicle and a vehicle ahead at a preset vehicle speed without you having to use the accelerator or brake pedal. Even further, with the steering assist function, when vehicle lane lines are detected, the function assists the driver in keeping the vehicle within the lane lines. If lane lines are not detected, the function provides the driver driving assistance in keeping the vehicle along the motion path with the vehicle ahead.
Do not rely completely on TJA:
-
The TJA is not an automated driving system. In addition, the functions have limitations. Do not rely completely on the system and always stay on course using the steering wheel.
-
Set a vehicle speed within the speed limit according to the road conditions and the weather conditions.
-
The TJA may not be able to detect a vehicle ahead depending on the type of vehicle ahead and its conditions, the weather conditions, and the road conditions. Additionally, the system might be unable to decelerate sufficiently if a vehicle ahead applies the brakes suddenly, another vehicle cuts into the driving lane, or the difference in vehicle speed between your vehicle and the vehicle ahead is larger, which could result in an accident. Check the surrounding conditions and always drive carefully while keeping a safe distance from vehicles ahead and on-coming vehicles.
For the purposes of safety, switch the TJA off when it is not being used.
Leaving the TJA turned on when it is not in use is dangerous as it could operate unexpectedly, resulting in an accident.
Do not use the TJA under the following conditions. Otherwise, it may result in an accident.
-
General roads other than expressways or highways (Driving under these conditions using the TJA is not possible.)
-
Roads with sharp curves and where vehicle traffic is heavy with insufficient space between vehicles, or roads where frequent and repetitive acceleration and deceleration occur (Driving under these conditions using the TJA is not possible).
-
When entering and exiting interchanges, service areas, and parking areas of expressways (If you exit an expressway while headway control is in use, the vehicle ahead will no longer be tracked and your vehicle may accelerate to the set speed).
-
Slippery roads such as icy or snow-covered roads and unpaved roads (Tires could spin causing you to lose vehicle control, or the stop hold control may not operate.)
-
Long, descending slopes (to maintain distance between vehicles, the system automatically and continuously applies the brakes which could result in the loss of brake power.)
-
Two-wheeled vehicles such as motorcycles or bicycles are ahead.
-
Slopes with a steep gradient (The vehicle ahead may not be detected correctly, your vehicle may slip while stopped by the stop hold control, or it may accelerate suddenly after it starts moving.)
-
Driving under bad weather conditions (rain, fog, and snow).
-
Tires of a different specified size are used, such as a temporary spare tire.
-
Tires with insufficient tread are used.
-
The tire pressures are not adjusted to the specified pressure.
-
The vehicle is being used to tow a camper or boat trailer.
-
Tire chains are used.
-
The vehicle is driven on roads with lane lines other than white (yellow) lines, such as an expressway.
Do not get out of the vehicle while the stop hold control is operating.
Getting out of the vehicle while the stop hold control is operating is dangerous as the vehicle may move unexpectedly and result in an accident. Before getting out of the vehicle, switch the TJA off, apply the parking brake, and then shift the selector lever to the P position.
Heed the following cautions so that the TJA can operate normally.
-
Turn the system off when the vehicle is running on a chassis roller.
-
Do not modify the vehicle's suspensions.
-
Always use wheels of the specified size for the front and rear wheels. Consult an Authorized Mazda Dealer for tire replacement.
-
The headway control does not detect the following as physical objects.
-
Vehicles approaching in the opposite direction
-
Pedestrians
-
Stationary objects (stopped vehicles, obstructions)
-
-
If a vehicle ahead is traveling at an extremely low speed, the system may not detect it correctly.
-
If there is a structure on the road or an object (such as a monorail) at a low height off the ground in front of the vehicle, the system may operate. Therefore, do not use the TJA.
-
Do not use the TJA under conditions in which close proximity warnings are frequently activated.
-
If it is necessary to accelerate for a lane change or the vehicle ahead brakes suddenly causing you to close in on the vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake pedal depending on the conditions.
-
While the TJA is in use, any intended engine braking does not occur even if you shift the selector lever. If deceleration is required, lower the vehicle speed setting or depress the brake pedal.
-
While braking by the TJA control is operating, you might hear an operation sound, however, this does not indicate a problem.
-
The brake lights turn on while braking by the TJA control is operating, however, they may not turn on while the vehicle is on a down slope at the set vehicle speed or traveling at a constant speed and following a vehicle ahead.
-
Under the following conditions, the TJA may not be able to detect white (yellow) lines or vehicles ahead correctly and the TJA may not operate normally.
-
The forward sensing camera (FSC) cannot recognize the area in front of the vehicle due to soiling or fog.
-
The white (yellow) lane lines are less visible because of dirt or paint flaking.
-
White (yellow) lane lines or vehicles ahead are less visible because of bad weather (rain, fog, or snow).
-
The vehicle is driven on a temporary lane or section with a closed lane resulting from construction where there might be multiple white (yellow) lane lines, or they are interrupted.
-
The camera picks up an obscure line, such as a temporary line being used for construction, or because of shade, unmelted snow, or grooves filled with water.
-
