Mazda Radar Cruise Control (MRCC)

The Mazda Radar Cruise Control (MRCC) system is designed to maintain headway
*1
control according to the vehicle speed using a radar sensor to detect the distance to a
vehicle ahead, which frees the driver 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.
The possible vehicle speed setting ranges are as follows:
(European models)
l
About 30 km/h (19 mph) to 200 km/h (124 mph)
(Except European models)
l
About 30 km/h (19 mph) to 145 km/h (90 mph)
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other highways
which do not require a lot of repeated acceleration and deceleration
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.
