Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function) (Automatic Transaxle) (Some Models)

The MRCC with Stop & Go function system is designed to maintain headway control*1 with a vehicle ahead according to your vehicle's speed using a radar sensor (front) to detect the distance to the vehicle ahead and a preset vehicle speed without you having to 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 such as if 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.

If the vehicle ahead stops while you are following behind it, your vehicle will stop and be held stopped automatically (stop hold control), and headway control will resume when you resume driving the vehicle such as by pressing the RES switch.

Also refer to the following before using the MRCC with Stop & Go function.

 

Do not rely completely on the MRCC with Stop & Go function:

The MRCC with Stop & Go function 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 drive carefully and verify the surrounding conditions and depress the brake pedal or accelerator pedal while keeping a safer distance from vehicles ahead or on-coming vehicles.

Do not use the MRCC with Stop & Go function system in the following locations, using the MRCC with Stop & Go function system at the following locations may result in an unexpected accident:

  • General roads other than highways (Driving under these conditions using the MRCC with Stop & Go function system is not possible.)

  • 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 MRCC with Stop & Go function 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 (Tyres could spin causing you to lose vehicle control, or the stop hold control may not operate.)

  • 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.)

  • Slopes with a steep gradient (The vehicle ahead may not be detected correctly, your vehicle may slide while stopped by the stop hold control, and it may accelerate suddenly after it starts moving.)

For safety purposes, switch the MRCC with Stop & Go function system off when it is not being used.

Do not get out of the vehicle while the stop hold control is operating:

Getting out of the vehicle while the stop hold control is operating is dangerous as the vehicle may move unexpectedly and result in an accident. Before getting out of the vehicle, switch the MRCC with Stop & Go function system off, shift the selector lever to the P position, and apply the parking brake.

If your vehicle is towed or you are towing something, switch the MRCC with Stop & Go function system off to prevent a mis-operation.

Close Caution

  • The MRCC with Stop & Go function system does not detect the following as physical objects.

    • Vehicles approaching in the opposite direction

    • Pedestrians

    • Stationary objects (stopped vehicles, obstructions)

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

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

  • Do not use the MRCC with Stop & Go function system under conditions in which 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 MRCC with Stop & Go function system is in use, it does not cancel even if the selector lever is operated and any intended engine braking does not occur. If deceleration is required, lower the set speed or depress the brake pedal.

  • The sound of the automatic brakes operating may be heard, however, it does not indicate a problem.

  • The brake lights turn on while the MRCC with Stop & Go function automatic braking is operating, however, they may not turn on while the vehicle is on a downslope at the set vehicle speed or travelling at a constant speed and following a vehicle ahead.
