PCS (Pre-Collision System) (if equipped)
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
Safety systems such as the brakes and seat belts are automatically
engaged to lessen impact and injuries to occupants as well as vehicle dam-
age when the radar sensor detects an unavoidable frontal collision.
n Pre-collision seat belts (front seats only)
The seat belts are immediately retracted as the effect of the pretensioner is
increased (→P. 54), to help prepare the driver and passengers. In the
event of sudden braking or skidding, the system will operate even if no
obstacle has been detected.
n Pre-collision brake assist
Applies greater braking force in relation to how strongly the brake pedal is
depressed.
n Pre-collision AVS
If the system determines that the collision is unavoidable, the operation of
AVS ( →P. 183) helps prevent the vehicle front from going down when
hard brakes are applied.
