When driving
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.
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.
■ Pre-collision seat belts
The front seat belts are immediately retracted as the effect of the preten-
sioner is increased (P. 79) to help prepare the driver and front passen-
ger. In the event of sudden braking or skidding, the system will operate
even if no obstacle has been detected.
However, the system will not operate in the event of skidding when the
TRAC/VSC systems are disabled.
■ Pre-collision brake assist
Applies greater braking force in relation to how strongly the brake pedal is
depressed.
■ 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.
