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.
     
Headway control is not possible if the vehicle ahead is driving faster than the 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 each time the switch is pressed.
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

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.
