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 damage 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 operating
properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
• When you turn ParkSense off, the instrument cluster
display will show  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 show the  PARKSENSE OFF  mes-
sage for as long as the vehicle is in REVERSE.
• 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
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.
• Ensure the ParkSense system is OFF if objects such as
bicycle carriers, trailer hitches, etc., are placed within 18
inches (45 cm) from the rear fascia/bumper while driv-
ing the vehicle. Failure to do so can result in the system
misinterpreting a close obstacle as a sensor problem,
causing the  PARKSENSE UNAVAILABLE SERVICE
REQUIRED  message to appear in the instrument cluster
display.
• On vehicles equipped with a tailgate, ParkSense should
be disabled when the tailgate is in the lowered or open
position and the vehicle is in REVERSE. A lowered
tailgate could provide a false indication that an obstacle
is behind the vehicle.148 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

The Front or Rear ParkSense switch LED will be ON when
Front or Rear ParkSense is disabled or requires service. The
Front or Rear ParkSense switch LED will be OFF when the
Front or Rear system is enabled. If the Front or Rear
ParkSense switch is pushed, and the system requires
service, the Front or Rear ParkSense switch LED will blink
momentarily, and then the LED will be ON.
Service The ParkSense Park Assist System
During vehicle start up, when the ParkSense System has
detected a faulted condition, the instrument cluster display
will actuate a single chime, once per ignition cycle, and it
will display the  PARKSENSE UNAVAILABLE WIPE
REAR SENSORS  ,  PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS  ,orthe  PARKSENSE UNAVAILABLE
SERVICE REQUIRED  message for five seconds. When the
gear selector is moved to REVERSE and the system has
detected a faulted condition, the instrument cluster display
will display a  PARKSENSE UNAVAILABLE WIPE REAR
SENSORS  ,  PARKSENSE UNAVAILABLE WIPE FRONT
SENSORS  or  PARKSENSE UNAVAILABLE SERVICE RE-
QUIRED  pop up message for five seconds. After five
seconds, a vehicle graphic will be displayed with  UN-
AVAILABLE  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 function-
ing properly. These arc alerts will interrupt the
 PARKSENSE UNAVAILABLE WIPE REAR SENSORS  ,
 PARKSENSE UNAVAILABLE WIPE FRONT SENSORS  ,
or  PARKSENSE UNAVAILABLE SERVICE REQUIRED 
messages if an object is detected within the five second
pop-up duration. The vehicle graphic will remain dis-
played for as long as the vehicle is in REVERSE. Refer to
“Instrument Cluster Display” in “Understanding Your
Instrument Panel” for further information.
If  PARKSENSE UNAVAILABLE WIPE REAR SENSORS 
or  PARKSENSE UNAVAILABLE WIPE FRONT SEN-
SORS  appears in the instrument cluster display make sure
the outer surface and the underside of the rear fascia/
bumper and/or front fascia/bumper is clean and clear of
snow, ice, mud, dirt or other obstruction and then cycle the
ignition. If the message continues to appear see an autho-
rized dealer.
If the  PARKSENSE UNAVAILABLE SERVICE RE-
QUIRED  message appears in the instrument cluster dis-
play, see an authorized dealer.154 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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.
• Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
• When you turn Front or Rear ParkSense off, the instru-
ment cluster display will read “FRONT PARKSENSE
OFF” or “REAR PARKSENSE OFF.” Furthermore, once
you turn Front or Rear 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 Front or Rear ParkSense is turned off, the instrument
cluster display will show the  FRONT PARKSENSE OFF  or
 REAR PARKSENSE OFF  message for five seconds, fol-
lowed by a vehicle graphic with  OFF  in the corresponding
side. This vehicle graphic will be displayed for as long as
the vehicle is in REVERSE. • 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
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 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.
• Use the ParkSense switch to turn the ParkSense system off
if obstacles such as bicycle carriers, trailer hitches, etc. are
placed within 18 in (45 cm) from the rear fascia/bumper.
Failure to do so can result in the system misinterpreting a
close obstacle as a sensor problem, causing the
“PARKSENSE UNAVAILABLE SERVICE REQUIRED”
message to be appear in the instrument cluster display.
• On vehicles equipped with a tailgate, ParkSense should
be disabled when the tailgate is in the lowered or open
position. A lowered tailgate could provide a false indi-
cation that an obstacle is behind the vehicle. 3UNDERSTANDING THE FEATURES OF YOUR VEHICLE 155

• Indicates vehicle speed.
4. Fuel Gauge
• The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
• The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
5. Temperature Gauge
• The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range. WARNING!A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats. If you decide to look
under the hood yourself, see “Maintaining Your Ve-
hicle”. Follow the warnings under the Cooling System
Pressure Cap paragraph.

NOTE: The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold heater
system. The number of cycles and the length of the cycling
operation is controlled by the engine control module. Post-
heat operation can run for several minutes, and then the
electrical system and voltmeter needle will stabilize.
3. Oil Pressure Gauge
• The pointer should always indicate some oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate
a lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
