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 sufficient 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.

WARNING

Do not rely completely on the Mazda Radar Cruise Control (MRCC) system and always 

drive carefully:

The Mazda Radar Cruise Control (MRCC) system is designed to reduce load on the 

driver, and although it maintains a constant vehicle speed, or specifically, it maintains 

a constant distance between your vehicle and the detected vehicle ahead according to 

the vehicle speed, the system has detection limitations depending on the type of vehicle 

ahead and its conditions, the weather conditions, and the road conditions. Additionally, 

the system may be unable to decelerate sufficiently to avoid hitting the vehicle ahead 

if the vehicle ahead applies the brakes suddenly or another vehicle cuts into the driving 

lane, which could result in an accident. Always verify the safety of the surrounding area 

and depress the brake pedal or accelerator pedal while keeping a safer distance from 

vehicles ahead or on-coming vehicles.

Do not use the Mazda Radar Cruise Control (MRCC) system 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. Roads where frequent and repetitive acceleration and 

deceleration occur (Driving under these conditions using the Mazda Radar Cruise 

Control (MRCC) system is not possible).



  When entering and exiting interchanges, service areas, and parking areas of highways 

(If you exit a highway 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 ice or snow-bound roads (The tires could spin causing you to 

lose vehicle control).



  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).
