WARNING: The collision warning system’s brake support can
only help reduce the speed at which a collision occurs if the
driver applies the vehicle’s brakes. The brake pedal must be pressed
just like for any typical braking situation.
Blocked sensor
If a message regarding a blocked
sensor is displayed, the radar signals
from the sensor, located behind a
fascia cover near the driver side of
the lower grille, have been
obstructed. When the radar signals
are obstructed, a vehicle ahead
cannot be detected and the collision
warning system will not function.
The following table lists possible
causes and actions for this message being displayed.

grille is dirty or obstructed in
some way Clean the grille surface in front of
the radar or remove the object
