2-4. Using other driving systems
Pre-Collision System
∗
∗
: If equipped
When the radar sensor detects possibility of a frontal collision, the pre-col-
lision system such as the brakes and seat belts are automatically engaged
to lessen impact and injuries to occupants as well as vehicle damage.
■
Pre-collision seat belts (front seats)
If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses
control of the vehicle.
However, the system will not operate in the event of skidding when the
VSC system is disabled.
■
Pre-collision brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is
depressed.
■
Pre-collision braking
When there is a high possibility of a frontal collision, the system warns the
driver using a warning light, warning display and buzzer. If the system
determines that a collision is unavoidable, the brakes are automatically
applied to help reduce the collision speed. Pre-collision braking function
can be turned on and off using the pre-collision braking off switch.

■
Suspension control (If equipped)
When it has been determined that there is a high possibility of a collision,
suspension firmness is adjusted appropriately.
