4-5. Using the driving support systems

ivi

This mode employs a radar sensor to detect the presence of vehicles
up to approximately 328 ft. (100 m) ahead, determines the current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.

Note that vehicle-to-vehicle distance will close in when traveling on down-
hill 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 dis-
tance switch.

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 suffi-
ciently 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 system control). After the vehicle ahead starts off, pressing the
“+ RES” switch or depressing the accelerator pedal will resume follow-up
cruising.

WARNING

■

Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a
vehicle is present in the blind spot. Do not overly rely on the BSM function.
The function cannot judge if it is safe to change lanes, therefore over reli-
ance could cause an accident resulting in death or serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.

256
