STARTING AND OPERATING 381
If “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
appears in the instrument cluster display, see an authorized
dealer.
Cleaning The ParkSense System
Clean the Rear Park Assist sensors with water, car wash soap
and a soft cloth. Do not use rough or hard cloths. In washing
stations, clean sensors quickly keeping the vapor jet/high
pressure washing nozzles at least 4
inches (10 cm) from the
sensors
. Do not scratch or poke the sensors. Otherwise, you
could damage the sensors.
ParkSense System Usage Precautions
NOTE:
Ensure that the rear bumper is free of snow, ice, mud, dirt
and de
bris to keep the ParkSense system operating properly.
Jackhammers, large trucks, and other vibrations could
affect
the performance of ParkSense.
When you turn ParkSense OFF, the instrument cluster
displa
y will read “PARKSENSE OFF.” Furthermore, once
you turn ParkSense OFF, it remains off until you turn it on
again, even if you cycle the ignition.
ParkSense, when on, will reduce the volume of the radio
when it
is sounding a tone.
Clean the ParkSense sensors regularly, taking care not to
scratc
h or damage them. The sensors must not be covered
with ice, snow, slush, mud, dirt or debris. Failure to do so
can result in the system not working properly. The Park
-
Sense system might not detect an obstacle behind the
f
ascia/b
umper, or it could provide a false indication that
an obstacle is behind the fascia/bumper.
Use the ParkSense switch to turn the ParkSense system
OFF if o
bjects such as bicycle carriers, trailer hitches, etc.
are placed within 12
inches (30 cm) from the rear fascia/
bumper.
Failure to do so can result in the system misinter-
preting a close object as a sensor problem, causing the
PARKSE
NSE UNAVAILABLE SERVICE REQUIRED”
message to be displayed in the instrument cluster display.
The operation of the rear sensors is automatically deacti-
vated
when the trailer's electric plug is inserted in the
vehicle
's tow hook socket. The rear sensors are automati-
cally reactivated when the trailer's cable plug is removed.
