MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM

The MRCC system maintains vehicle speed and following distance 

using a radar sensor to detect a vehicle ahead. The driver simply 
presets the vehicle speed between 19 mph and 90 mph and the 
system will maintain a safe following distance without having to 
turn the cruise control off.

The system operates in two modes: 

CONSTANT SPEED MODE: When no 
vehicle is detected ahead, the driver’s set 
speed is maintained.

HEADWAY CONTROL MODE: When a vehicle 
is detected ahead, a distance between your 
vehicle and the vehicle ahead is maintained.

Setting the MRCC 

When the MODE switch is pushed, the vehicle speed and the distance 
between vehicles while in headway control can be set. The MRCC 
indication is shown in the Active Driving Display.

NOTE:

 The radar for the MRCC is located behind the Mazda  

emblem in the grille. Keep this area clean to avoid the system not 
working properly.

How to set the speed: 

1 

Adjust the vehicle to the desired speed using the accelerator pedal.

2 

 Push the SET + or SET – switch. The set speed and the inter-vehicle distance display filled 
with white lines are displayed in the Active Driving Display and the MRCC indicator light 
(green) turns on simultaneously.
