Driving in vehicle-to-vehicle distance control mode

This mode employs a radar sensor to detect the presence of vehicles up to

approximately 400 ft. (120 m) ahead, determines the current vehicle-to-

vehicle following distance, and operates to maintain a suitable following

distance from the vehicle ahead.

Note that vehicle-to-vehicle distance will close in when traveling on long downhill

Example of constant speed cruising

When there are no vehicles ahead

The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle

distance can also be set by operating the vehicle-to-vehicle distance control.

Example of deceleration cruising

When the vehicle ahead is driving slower than the set speed

When a vehicle is detected running ahead of you, the system automatically decel-

erates your vehicle. When a greater reduction in vehicle speed is necessary, the

system applies the brakes. A warning tone warns you when the system cannot

decelerate sufficiently to prevent your vehicle from closing in on the vehicle
