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
The front seat belts are immediately retracted as the effect of the preten-
sioner is increased (
→
P. 51), to provide even greater constraining force to
protect the driver and passengers. In the event of sudden braking or skid-
ding, 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
Obstacles not detected
The sensor cannot detect plastic obstacles such as pylons. There may also be occa-
sions when the sensor cannot detect pedestrians, animals, bicycles, motorcycles,
trees, or snowdrifts.
