*Some models.
Mazda Radar Cruise Control (MRCC) *
The Mazda Radar Cruise Control (MRCC) system is designed to maintain headway control *1
according to the vehicle speed using a radar sensor (front) to detect the distance to a vehicle
ahead, and by presetting the vehicle speed between 30 km/h (19 mph) and 145 km/h (90
mph), the driver is freed from having to constantly use the accelerator or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and the vehicle ahead
detected by the Mazda Radar Cruise Control (MRCC) system.
Additionally, if your vehicle starts closing in on the vehicle ahead because, for example, the
vehicle ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a suf ¿ cient distance between the vehicles.
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other highways
which do not require a lot of repeated acceleration and deceleration.

the brake warning is indicated in the display. Always verify the safety of the surrounding
area and depress the brake pedal while keeping a safer distance from the vehicle ahead.
Additionally, always keep a safer distance from the vehicles behind you.

y If a vehicle ahead is detected while traveling at a constant speed, the vehicle-ahead
indication is displayed and headway control is performed. Additionally, when a vehicle
ahead is no longer detected, the vehicle-ahead indication turns off and the system
switches back to travel at constant speed.
y Headway control is not possible if the vehicle ahead is driving faster than the set speed.
Adjust the system to the desired vehicle speed using the accelerator pedal.

How to Set the Distance Between Vehicles During Headway Control
The distance between vehicles is set to a shorter distance each time the
switch is pressed.
The distance between vehicles is set to a longer distance by pressing the
switch. The
distance-between-vehicles can be set to 4 levels; Long, medium, short, and extremely short
distance.

N O T E
y The distance between vehicles differs depending on the vehicle speed, and the slower the
vehicle speed, the shorter the distance.
y When the ignition is switched to ACC or OFF and then the engine is started again, the
system automatically sets the distance between vehicles to the previous setting.
Changing the Set Vehicle Speed
Changing the set vehicle speed using the
SET switch
Press the SET
switch to accelerate.
Press the SET
switch to decelerate.
The set vehicle speed changes as follows
each time the SET switch is pressed.
Short press 1 km/h (1 mph)
Long press 10 km/h (5 mph)
N O T E
For example, the set vehicle speed is
changed by pressing the SET switch four
times as follows:
The vehicle speed accelerates or
decelerates by 4 km/h (4 mph).
To accelerate using the accelerator
pedal
Depress the accelerator pedal and press
and release the SET
or SET switch at
the desired speed. If a switch cannot be
operated, the system returns to the set
speed when you release your foot from the
accelerator pedal.
CAUTION
The warnings and brake control do not
operate while the accelerator pedal is
depressed.
N O T E y When accelerating using the SET
switch while in headway control, the set
vehicle speed can be adjusted but
acceleration is not possible. If there is
no longer a vehicle ahead, acceleration
continues until reaching the set vehicle
speed. Check the set vehicle speed by
viewing the set vehicle speed display in
the multi-information display and the
active driving display.
y When depressing the accelerator pedal,
the inter-vehicle distance display in the
multi-information display changes to
the white-line display.
y The minimum settable speed is 30 km/h
(19 mph). If the set vehicle speed
reaches 30 km/h (19 mph) using the
switch operation, constant speed travel
is maintained at about 30 km/h (19
mph) even if the SET
switch is
pressed. The Mazda Radar Cruise
Control (MRCC) system is not canceled.
