Driving in vehicle-to-vehicle distance control mode
This mode employs a radar sensor to detect the presence of vehi-
cles up to approximately 120 m (400 ft.) ahead, determines the cur-
rent 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 slopes.
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 automat-
ically decelerates 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 ahead.
