Mazda Radar Cruise Control (MRCC)

Mazda Radar Cruise Control (MRCC)

MRCC is a system that reduces load on the driver through constant speed and headway control. The function performs headway control to maintain the distance with a vehicle ahead at a constant preset speed without you having to depress the accelerator or brake pedal.

Warnings and Cautions for Using the Mazda Radar Cruise Control (MRCC)

WARNING
Do not rely completely on the MRCC. The MRCC may not be able to detect a vehicle ahead depending on the type of vehicle ahead and its conditions, the weather conditions, and the road conditions. Additionally, the system might be unable to decelerate sufficiently if the vehicle ahead applies the brakes suddenly or another vehicle cuts into your lane, which could result in an accident.
Always check the surrounding conditions and depress the brake pedal or accelerator pedal while keeping a safe distance from a vehicle ahead or a vehicle following behind you.
Do not use the MRCC under the following conditions. Otherwise, it may result in an accident.

• The vehicle is driven on roads other than highways.
• The vehicle is driven on roads with sharp curves or with heavy traffic where sufficient distances between vehicles cannot be kept.
• The vehicle is driven on roads where acceleration and deceleration are frequently repeated.
• The vehicle is exiting the main lane on an expressway to enter an interchange, a rest area, or a parking area.
• The vehicle is driven on slippery roads such as icy roads,
  snow-covered roads, and unpaved roads.
• The vehicle is driven on a long downslope.
• The vehicle is driven on a steep slope.
• A two-wheeled vehicle such as a motorcycle or bicycle is traveling ahead.

Switch the MRCC off when it is not being used.
Leaving the MRCC on when it is not in use is dangerous as it could operate unexpectedly, resulting in an accident.

Do not leave the vehicle while the vehicle is stopped by the MRCC control.
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 leaving the vehicle, switch the MRCC off, shift the selector lever to the P position, and apply the parking brake.

CAUTION

• If the vehicle is towed or you are towing something, switch the MRCC off.
• Turn off the MRCC when the vehicle is running on a chassis roller.

How to Use the Mazda Radar Cruise Control (MRCC)

MRCC operation conditions
The MRCC can be set when all of the following conditions are met.

• The brake pedal is not depressed.
• The vehicle speed is about 0 km/h (0 mph) to 145 km/h (90 mph).
• The Hill Descent Control is not operating.
  Setting the MRCC

1. Press the MRCC switch to turn the system on.
   When the system is on, the MRCC standby indication (white) the screen.
2. Accelerate to the desired speed.
3. Set the vehicle speed by pressing the RES switch up (SET+) or down (SET-).

Constant speed driving starts when the vehicle speed is set. In addition, the set speed is displayed on the screen, and the MRCC standby indication (white) changes to the MRCC set indication (green)If a vehicle ahead is detected while traveling at a constant speed, the system switches to headway control. The vehicle ahead indication is displayed on the screen while in headway control.

NOTE

• While in EV mode, acceleration may be restricted and the vehicle may not be able to be driven at the set speed.
  Refer to Mazda Intelligent Drive Select (Mi-Drive) on page 5-95.
• If there is a structure on the road or an obstruction at a low height off the ground in front of the vehicle, the system may recognize it as a vehicle ahead.
• Acceleration and deceleration by accelerator pedal operation takes priority while travelling at a constant speed or in headway control. When the accelerator pedal is released, the vehicle returns to driving at a constant speed or headway control at the set speed.
• If a vehicle ahead is travelling at an extremely low speed, the system may not detect it correctly.
• While driving using the MRCC, the intended engine braking is not applied even if the selector lever is operated.
• The brake lights turn on while the brakes are operating by the MRCC control.
• The MRCC is also turned off automatically when the vehicle power is switched OFF.
• If the distance between vehicles control is disabled using Mazda Connect, the system switches to the cruise control. At this time, the MRCC switch functions as the cruise control switch.
  Refer to the Settings section in the Mazda Connect Owner’s Manual.
  If the vehicle power is switched OFF while the distance between vehicles control is disabled, the distance between vehicles control is enabled automatically the next time the vehicle power is switched ON.

If the vehicle ahead stops during headway control, your vehicle in headway control
also stops. When the vehicle is stopped, the MRCC indicator light in the instrument cluster turns on.
When the vehicle ahead accelerates from a stop and one of the following operations is performed, your vehicle starts driving.

• Press the RES switch.
• Depress the accelerator pedal.

If you do not start driving the vehicle after the vehicle ahead has resumed driving, the system urges the driver to resume driving.

NOTE

• If the vehicle ahead resumes driving within 3 seconds after the vehicle was stopped by the system, your vehicle also resumes driving automatically.
• If the vehicle is stopped by the system continuously for 10 minutes or longer, the parking brake is applied automatically. At this time, the MRCC is canceled.
• Even if the MRCC is canceled while the vehicle is stopped, the vehicle is held in its stopped position.
  Refer to AUTOHOLD
• If the MRCC is canceled while the vehicle is stopped and there is no vehicle ahead, you cannot resume driving the vehicle using the RES switch. Depress the accelerator pedal and start driving the vehicle.

Changing the set vehicle speed
Changing the set vehicle speed using the RES switch
Press the RES switch up (SET+) or down (SET-) to the desired speed.

• Press and release immediately: 1 km/h (1 mph)

Cruising & Traffic Support (CTS)*

The CTS is a system that reduces the load on the driver while the vehicle is driven on expressways or highways. The CTS has the following 2 functions.

Constant speed/Headway control function
The function performs headway control to maintain the distance with a vehicle ahead at a constant preset speed without you having to depress the accelerator or brake pedal.

Steering wheel assist function
When vehicle lane lines are detected, the function assists your steering wheel operation to follow the vehicle lane lines.
When vehicle lane lines are not detected, the function assists your steering wheel operation to follow the trajectory of the vehicle ahead.

Warnings and Cautions for Using Cruising & Traffic Support (CTS)

WARNING
Do not rely completely on the CTS.

• The CTS is not an automated driving system. Therefore, the function has limitations. Do not rely completely on the system and always stay on course using the steering wheel.
• Set a vehicle speed within the speed limit according to the road conditions and the weather conditions.
• The CTS may not be able to detect a vehicle ahead depending on the type of vehicle ahead and its conditions, the weather conditions, and the road conditions. Additionally, the system might be unable to decelerate sufficiently if the vehicle ahead applies the brakes suddenly or another vehicle cuts into your lane, which could result in an accident.

Do not use the CTS under the following conditions. Otherwise, it may result in an accident.

• The vehicle is driven on roads other than expressways and highways.
• The vehicle is driven on roads with sharp curves or with heavy traffic where sufficient distances between vehicles cannot be kept.
