Service the Park Assist System
In case of malfunction of the Park Assist
system, the instrument cluster will
actuate a single sound, once per ignition
cycle. The instrument cluster will display
a message when any of the rear or front
sensor(s) are blocked by snow, mud, or
ice and the vehicle is into R (Reverse), D
(Drive) or N (Neutral) mode.
The instrument cluster will display
a message when any of the rear or
front sensors are damaged and require
service.
When the transmission is set to R
(Reverse), D (Drive) or N (Neutral)
mode and the system has detected
a faulted condition, the instrument
cluster will display the message and the
corresponding soft telltale. Under this
condition Park Assist will not operate.
See "Warning and Indicator Lights" in
section "Dashboard Instruments and
Controls" for further information. A
related graphic will also be displayed on
the MIA screen.
If the instrument cluster displays a
message prompting you to clean the
sensors, make sure the outer surface and
the underside of the rear bumper and/or
front bumper is clean and clear of snow,
ice, mud, dirt or other obstruction and
then cycle the ignition device. If the
message continues to appear contact
the Service Network.
If a failure message is displayed on the
instrument cluster, contact the Service
Network.

Cleaning the Park Assist Sensors
When cleaning the sensors, take special
care not to scratch or damage them;
therefore, do not use dry, rough or hard
cloths.
The sensors must be washed with clean
water, possibly adding car shampoo.
Should you need to repaint the bumper
or in case of paint touch-ups in the
sensor area, please contact exclusively
the Service Network.
Incorrect paint application could affect
the parking sensors operation.
Park Assist System Usage
Precautions
NOTE:
• Jackhammers, large trucks, and other
vibrations could affect the performance
of Park Assist.
• Objects such as bicycle carriers, trailer
hitches, etc., must not be placed within
30 cm (12 in) from the rear bumper
while driving the vehicle. Failure
to do so can result in the system
misinterpreting a close object as a
sensor problem, causing the service
Park Assist message to be displayed in
the instrument cluster.
