Driving

This mode employs a radar to detect the presence of vehicles up to approximately 
328 ft. (100 m) ahead, determines the current vehicle-to-vehicle following dis-
tance, and operates to maintain a suitable following distance from the vehicle 
ahead. The desired vehicle-to-vehicle distance can also be set by operating the 
vehicle-to-vehicle distance switch.

When driving on downhill slopes, the vehicle-to-vehicle distance may become shorter.

Example of constant speed cruising
When there are no vehicles ahead

The vehicle travels at the speed set by the driver.

Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears

When a vehicle is detected running ahead of you, the system automatically decelerates 
your vehicle. When a greater reduction in vehicle speed is necessary, the system applies 
the brakes (the stop lights will come on at this time). The system will respond to changes in 
the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by 
the driver. Approach warning warns you when the system cannot decelerate sufficiently to 
prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is stopped by sys-
tem control). After the vehicle ahead starts off, pushing the cruise control lever up or 
depressing the accelerator pedal (start-off operation) will resume follow-up cruising. If the 
start-off operation is not performed, system control continues to keep your vehicle 
stopped.
When the turn signal lever is operated and your vehicle moves to an overtaking lane while 
driving at 50 mph (80 km/h) or more, the vehicle will accelerate to help to overtake a 
passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely based on
