Service The ParkSense Park Assist
System
During vehicle start up, when the ParkSense
System has detected a faulted condition, the
instrument cluster will actuate a single chime,
once per ignition cycle, and it will display the
"PARKSENSE UNAVAILABLE WIPE REAR
SENSORS", "PARKSENSE
WIPE FRONT SENSORS",
"PARKSENSE UNAVAILABLE SERVICE RE-

instrument cluster display will display a
"PARKSENSE UNAVAILABLE WIPE REAR
SENSORS", "PARKSENSE
WIPE FRONT SENSORS" or "PARKSENSE
UNAVAILABLE SERVICE REQUIRED" pop up
message for five seconds. After five seconds, a
vehicle graphic will be displayed with "UNAVAIL-
ABLE" at either the front or rear sensor location
depending on where the fault is detected. The
system will continue to provide arc alerts for the
side that is functioning properly. These arc alerts

WIPE REAR SENSORS", "PARKSENSE UN-
AVAILABLE WIPE FRONT SENSORS", or
"PARKSENSE UNAVAILABLE SERVICE RE-
QUIRED" messages if an object is detected
within the five second pop-up duration. The

car wash soap and a soft cloth. Do not use
UNAVAILABLE
rough or hard cloths. In washing stations, clean
sensors quickly keeping the vapor jet/high pres-

sensors. Otherwise, you could damage the sen-
sors.
ParkSense System Usage
Precautions
NOTE:
• Ensure that the front and rear bumper are
free of snow, ice, mud, dirt and debris to keep
the ParkSense system operating properly.
• Construction equipment, large trucks, and
other vibrations could affect the performance
of ParkSense.
• When you turn ParkSense off, the instrument
cluster display 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 key.
• When you move the gear selector to the
REVERSE position and ParkSense is turned
off, the instrument cluster display will read
"PARKSENSE OFF" for as long as the ve-
hicle is in REVERSE.
• ParkSense, when on, will reduce the volume
of the radio when it is sounding a tone.
• Clean the ParkSense sensors regularly, tak-
ing 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 ob-
stacle behind or in front of the fascia/bumper,
or it could provide a false indication that an
obstacle is behind or in front of the
fascia/bumper.
