NOTE:
If the radar sensor wipe warning
message occurs frequently (e.g. more
than once on every trip) without any
snow, rain, mud, or other obstruction,
have the radar sensor realigned at the
Service Network.
Clean Front Windshield Warning
This warning will display and also a
chime will indicate when conditions
temporarily limit system performance
due to camera poor or failed signal
reception. This most often occurs at
times of poor visibility, such as in snow
or heavy rain and fog. The ACC and
FCW systems may also become
temporarily blinded due to
obstructions, such as mud, dirt, or ice
on windshield and fog on the inside of
glass or when driving in bad weather.
In these cases, the system will have
degraded performance.
The ACC and FCW systems will recover
operation after the vehicle has left
these areas. Under rare conditions,
when the camera is not tracking any
vehicles or objects in its path this
warning may temporarily occur.
If weather conditions are not a factor,
the driver should examine the
windshield and the camera. They may
require cleaning or removal of an
obstruction.
When the condition that created
limited functionality is no longer
present, the ACC and FCW systems will
return to full functionality.
NOTE:
If the windshield wiper warning
message occurs frequently (e.g. more
than once on every trip) without any
snow, rain, mud, or other obstruction,
have the windshield and front camera
inspected at the Service Network.
Service ACC/FCW Warning
If the ACC and FCW systems turn off,
and the system displays a service
warning, there may be an internal
system fault or a temporary
malfunction that limits functionality.
Although the vehicle is still driveable
under normal conditions, ACC and
FCW will be temporarily unavailable. If
this occurs, try activating ACC and
FCW again later, following a key cycle.
If the problem persists, contact the
Service Network.
Precautions while Driving with
ACC
Towing a Trailer
WARNING!
Towing a trailer when using ACC can
lead to serious system failures which
can cause severe accidents.
Offset Driving
ACC may not detect a vehicle in the
same lane that is offset from your
direct line of travel, or a vehicle
merging in from a side lane. There
may not be sufficient distance to the
vehicle ahead. The offset vehicle may
move in and out of the line of travel,
which can cause your vehicle to brake
or accelerate unexpectedly.
