Note:
It is recommended that you turn the
collision warning system off if a snow plow
or similar object is installed in such a way
that it may block the radar sensor. Your
vehicle will remember the selected setting
across key cycles.
Note:
When possible, the manufacturer
recommends using the highest sensitivity
setting. If warnings are too frequent, you can
reduce your system's sensitivity. Reduced
sensitivity causes fewer and later system
warnings. See
General Information
(page
8).
Blocked Sensors
E183741
If a blocked sensor message appears in the
information display, dirt, water, or an object
is blocking the sensor. The sensor is
located behind a cover near the driver side
of the lower grille. If anything blocks the
sensor, your vehicle cannot see through
the sensor, and the collision warning
system will not work. Possible causes for
the blocked sensor message and corrective
actions are listed below.
Action
Cause
Clean the radar sensor cover or remove the
obstruction
The radar sensor cover in the grille is dirty
or obstructed
Wait a short time. The radar may take
several minutes to reset after you remove
the obstruction
The surface of the radar sensor cover is
clean but the message remains in the
display
The collision warning system is temporarily
disabled. Shortly after weather conditions
improve, the collision warning system
automatically reactivates
Heavy rain, spray, snow or fog in the air
interferes with the radar signals
The collision warning system is temporarily
