Blocked Sensors
If a message regarding a blocked
sensor appears in the information
display, the radar signals from the
sensor have been obstructed. The
sensors are located behind a fascia
cover near the driver side of the
lower grille. When the sensors are
obstructed, a vehicle ahead cannot
be detected and the collision
warning system does not function.
The following table lists possible
causes and actions for this message being displayed.
Cause
Action
The surface of the radar in the
grille is dirty or obstructed in
some way
Clean the grille surface in front of the
radar or remove the object causing the
obstruction
The surface of the radar in the
grille is clean but the message
remains in the display
Wait a short time. It may take several
minutes for the radar to detect that it is no
longer obstructed
Heavy rain, spray, snow, or fog
is interfering with the radar
signals
The collision warning system is temporarily
disabled. Collision warning should
automatically reactivate a short time after
the weather conditions improve.
Swirling water, or snow or ice
on the surface of the road may
interfere with the radar signals
The collision warning system is temporarily
disabled. Collision warning should
automatically reactivate a short time after
the weather conditions improve.
System Limitations
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 any typical braking situation.
Due to the nature of radar technology, there may be certain instances
where vehicles do not provide a collision warning. These include:
•
Stationary vehicles or vehicles moving below 6 mph (10 km/h).
