Note: We recommend that you switch the
system off if you install a snow plow or
similar object in such a way that it may
block the radar sensor. Your vehicle
remembers the selected setting across key
cycles.
Note: If you perceive warnings being too
frequent or disturbing, you can reduce the
warning sensitivity, though the manufacturer
recommends using the highest sensitivity
setting where possible. Setting to a lower
sensitivity would lead to fewer and later
system warnings. See General Information
(page 110).
Blocked Sensors
E183741
If a message regarding a blocked sensor
appears in the information display, the
radar signals from the sensor are
obstructed. The sensors are behind a
fascia cover near the driver side of the
lower grille. When the sensors are
obstructed, the system cannot detect a
vehicle ahead and the system does not
function. The following table lists possible
causes and actions for when this message
displays.
ActionCause
Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion.
The surface of the radar in the grille is dirty
or obstructed in some way.
Wait a short time. It may take several
minutes for the radar to detect that there
are no obstructions.
The surface of the radar in the grille is clean
but the message remains in the display.
The system temporarily disables and
reactivates a short time after the weather
conditions improve.
Heavy rain, spray, snow or fog is interfering
with the radar signals.
The system temporarily disables and
reactivates a short time after the weather
conditions improve.
Swirling water, snow or ice on the surface
of the road may interfere with the radar
signals.
System Limitations
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).
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lane.
• Severe weather conditions.
