Driving
This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehi-
cle-to-vehicle following distance, and operates to maintain a suitable
following distance from the vehicle ahead. The desired vehi-
cle-to-vehicle distance can also be set by operating the vehi-
cle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may
become shorter.
Example of const ant 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 ahea d of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to ch anges 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 suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, yo ur vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+RES” switch or depressing the acce lerator pedal (start-off operation) will
resume follow-up cruising. If the start-of f operation is not performed, system
control continues to keep your vehicle stopped.
