Cleaning the ParkSense System

Clean the ParkSense sensors with water, car wash soap
and a soft cloth. Do not use rough or hard cloths. Do not
scratch or poke the sensors. Otherwise, you could dam-
age the sensors.

ParkSense System Usage Precautions

NOTE:
• Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep the ParkSense system operat-
ing properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense .
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 199
• When you turn ParkSense off, the instrument cluster
will display "PARK ASSIST OFF." Furthermore, once
you turn ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition key.
• When you move the shift lever to the REVERSE
position and ParkSense is turned off, the instrument
cluster will display "PARK ASSIST OFF" message for
as long as the vehicle is in REVERSE.
• ParkSense , when on, will MUTE the radio when it is
sounding a tone.
• Clean the ParkSense sensors regularly, taking care
not to scratch 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 ParkSense system might not detect an
obstacle behind the fascia/bumper, or it could provide
a false indication that an obstacle is behind the fascia/
bumper.
