Setting the System

The MRCC system operates when all of the following conditions are met.

  • Vehicle speed is 30 km/h (19 mph) to 145 km/h (90 mph)

  • The MRCC is turned on.

  • The brake pedal is not depressed.

  • The electric parking brake (EPB) is released (electric parking brake (EPB) indicator light is turned off).

  • There is no problem with the DSC.

  • All the doors are closed.

  • The driver's seat belt is fastened.

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

Turning on the system

When the MODE switch is pressed once, the MRCC system turns on, and the MRCC main indication (white) turns on and the vehicle speed and the distance between the vehicles while in headway control can be set.

In addition, the MRCC system display indication is displayed on the multi-information display and the active driving display at the same time.

 

  • If the ignition is switched off while the MRCC system is operating, the system will be operable when the ignition is switched ON the next time.

During travel at constant speed

During travel under headway control

 

  • If a vehicle ahead is detected while travelling at a constant speed, the vehicle-ahead indication is displayed and headway control is performed. Additionally, when a vehicle ahead is no longer detected, the vehicle-ahead indication turns off and the system switches back to travel at constant speed.

  • The lowest possible speed which can be set on the MRCC system is 30 km/h (19 mph).

  • Headway control is not possible if the vehicle ahead is driving faster than your vehicle's set speed. Adjust the system to the desired vehicle speed using the accelerator pedal.

How to set the distance-between-vehicles during headway control

The distance-between-vehicles is set to a shorter distance by pressing the switch. The distance-between-vehicles is set to a longer distance by pressing the switch. The distance-between-vehicles can be set to 4 levels; Long, medium, short, and extremely short distance.

Distance-between-vehicles guideline

(at 80 km/h (50 mph) vehicle speed)

Indication on multi-information display

Indication on active driving display*1

Long (about 50 m (164 ft))

Medium (about 40 m (131 ft))

Short (about 30 m (98 ft))

Extremely short (about 25 m (82 ft))

  1. Displays a pop-up image in the active driving display only when the driver operates the switch.

 

  • The distance-between-vehicles differs depending on the vehicle speed, and the slower the vehicle speed, the shorter the distance.

  • When the ignition is switched to ACC or OFF and then the engine is started again, the system automatically sets the distance-between-vehicles to the previous setting.
