Mazda Radar Cruise Control (MRCC) system
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, which frees the driver from having to constantly use the accelerator or brake pedals.
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:
For details, refer to Section 4, “i-ACTIVSENSE”.
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other
highways which do not require a lot of repeated acceleration and deceleration.
•(European models)
About 30 km/h (19 mph) to 200 km/h (124 mph)
•(Except European models)
About 30 km/h (19 mph) to 145 km/h (90 mph)
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.
WARNING
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.
•When entering and exiting interchanges, service areas, and parking areas of highways.
• Slippery roads such as ice or snow-bound roads.
• Long descending slopes.
*1 Headway Control: Control of the distance between your vehicle and the vehicle ahead
detected by the Mazda Radar Cruise Control (MRCC) system.
