4-5. Using the driving support systems

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 and follow-up 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. 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. A warning tone 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. After the vehicle ahead starts off,

pushing the cruise control lever up or depressing the accelerator pedal will

resume follow-up cruising.
