Mazda Radar Cruise Control (MRCC) (Some Models)

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.

 


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).

For the purposes of safety, switch the Mazda Radar Cruise Control (MRCC) system off when it is not being used.

  • The Mazda Radar Cruise Control (MRCC) system operates when all of the following conditions are met.

    • The vehicle speed is about 30 km/h (19 mph) to 145 km/h (90 mph).

    • The Mazda Radar Cruise Control (MRCC) system is turned on.

    • The parking brake is not applied.

    • The Smart Brake Support (SBS) is not malfunctioning.

    • The Dynamic Stability Control (DSC) is operating normally.

    • The selector lever is in the drive (D) position or manual (M) position (manual mode).

    • All doors are closed.

    • The driver's seat belt is fastened.

  • In the following cases, the warnings may not activate even if your vehicle starts closing in on the vehicle ahead.

    • You are driving at the same speed as the vehicle ahead.

    • Directly after the Mazda Radar Cruise Control (MRCC) system has been set.

    • When the accelerator pedal is depressed or directly after the accelerator pedal is released.

    • Another vehicle cuts into the driving lane.

  • The following are not detected as physical objects.

    • Vehicles approaching in the opposite direction

    • Pedestrians

    • Stationary objects (stopped vehicles, obstructions)

  • If a vehicle ahead is traveling at an extremely low speed, the system may not detect it correctly.

  • During headway control travel, do not set the system on two-wheeled vehicles such as motorcycles and bicycles.

  • Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in which the close proximity warnings are frequently activated.

  • During headway control travel, the system accelerates and decelerates your vehicle in conjunction with the speed of the vehicle ahead. However, if it is necessary to accelerate for a lane change or if the vehicle ahead brakes suddenly causing you to close in on the vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake pedal depending on the conditions.

  • While the Mazda Radar Cruise Control (MRCC) system is in use, it does not cancel even if the selector lever is operated and any intended engine braking will not occur. If deceleration is required, lower the vehicle speed setting or depress the brake pedal.

  • The brake lights are illuminated while the Mazda Radar Cruise Control (MRCC) automatic braking is operating.

  • If there is a problem with the Mazda Radar Cruise Control (MRCC) system, a message is displayed in the multi-information display. Check the center display to verify the problem and then have your vehicle inspected by an Authorized Mazda Dealer.

    Refer to Message Indicated on Display (Search).

  • The headway control operation can be canceled and the system can be switched to only cruise control. Refer to Cruise Control Function (Search).
