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

NOTE

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

The set speed and the inter-vehicle distance display filled with white lines is displayed.

The MRCC with Stop & Go function main indication (white) switches to the MRCC with Stop & Go function set indication (green) at the same time.

NOTE

• If a vehicle ahead is detected while traveling 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 with Stop & Go function 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.

NOTE

• 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.

How to change the set vehicle speed

To accelerate/decelerate using the SET switch

When you press the SET+ switch, the vehicle accelerates and when you press the SET- switch, it decelerates.

NOTE For example, the set vehicle speed is changed by pressing the SET switch four times as follows: The vehicle speed accelerates or decelerates by 4 km/h (4 mph).

To increase speed using accelerator pedal

Depress the accelerator pedal and press and release the SET+ switch or SET- switch at the desired speed. If the switch is not operated, the system returns to the set speed after you release your foot from the accelerator pedal.

CAUTION The warnings and brake control do not operate while the accelerator pedal is depressed.

NOTE

• The setting speed can be changed by operating the SET+ switch or SET- switch during stop hold control.
• When accelerating using the SET+ switch while in headway control, the set vehicle speed can be adjusted but acceleration is not possible. If there is no longer a vehicle ahead, acceleration continues until reaching the set vehicle speed. For the set vehicle speed, check the set vehicle speed indication in the display.
• When depressing the accelerator pedal, the inter-vehicle distance indication in the display changes to the white-line indication.
