PCS (Pre-Collision System)
∗
Radar sensor
Detects vehicles or other obsta-
cles on or near the road ahead and
determines whether a collision is
imminent based on the position,
speed, and heading of the obsta-
cles.
Grille cover
Radar sensor
When the radar sensor detects possibility of a frontal collision, the pre-col-
lision system such as the brake assist and seat belts are automatically
engaged to lessen impact and injuries to occupants as well as vehicle dam-
age.
■
Pre-collision seat belts
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, when the VSC systems are disabled, the system will not operate
in the event of skidding.
■
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.
