• 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.
CAUTION!• ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below
the sensors will not be detected when they are in
close proximity. (Continued) CAUTION! (Continued)• The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time when
an obstacle is detected. It is recommended that the
driver looks over his/her shoulder when using
ParkSense.
WARNING!• Drivers must be careful when backing up even
when using ParkSense. Always check carefully
behind your vehicle, look behind you, and be sure
to check for pedestrians, animals, other vehicles,
obstructions, and blind spots before backing up.
You are responsible for safety and must continue to
pay attention to your surroundings. Failure to do so
can result in serious injury or death. (Continued) 3UNDERSTANDING THE FEATURES OF YOUR VEHICLE 195

FRONT SENSORS  ,orthe  PARKSENSE UNAVAIL-
ABLE SERVICE REQUIRED  message for five seconds.
When the gear selector is moved to Reverse and the
system has detected a faulted condition, the Electronic
Vehicle Information Center (EVIC) or Driver Information
Display (DID) will display a  PARKSENSE UNAVAIL-
ABLE WIPE REAR SENSORS  ,  PARKSENSE UNAVAIL-
ABLE WIPE FRONT SENSORS  or  PARKSENSE UN-
AVAILABLE SERVICE REQUIRED  pop up message for
five seconds. After five seconds, a car graphic will be 3UNDERSTANDING THE FEATURES OF YOUR VEHICLE 201

displayed with  UNAVAILABLE  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
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 car graphic
will remain displayed for as long as the vehicle is in
REVERSE. Refer to “Electronic Vehicle Information Cen-
ter (EVIC) or  Driver Information Display (DID)” for
further information.
If  PARKSENSE UNAVAILABLE WIPE REAR SENSORS 
or  PARKSENSE UNAVAILABLE WIPE FRONT SEN-
SORS  appears in the Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID) 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 authorized dealer.
If the  PARKSENSE UNAVAILABLE SERVICE RE-
QUIRED  message appears in the EVIC/DID, see an
authorized dealer.
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 front and rear bumper are free of snow,
ice, mud, dirt and debris to keep the ParkSense system
operating properly.202 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

• Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
• When you turn Front or Rear ParkSense off, the
instrument cluster will display “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 will display  FRONT PARKSENSE
OFF  or  REAR PARKSENSE OFF  message for five
seconds, followed by a car graphic with  OFF  in the
corresponding side. This car 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 displayed in the
instrument cluster.

should be disabled when the tailgate is in the lowered 3UNDERSTANDING THE FEATURES OF YOUR VEHICLE 203

CAUTION!Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H”, turn the engine off immediately
and call an authorized dealer for service. 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
Vehicle”. Follow the warnings under the Cooling

1. Tachometer
• Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Voltmeter
• When the engine is running, the gauge indicates the
electrical system voltage. The pointer should stay
within the normal range if the battery is charged. If
the pointer moves to either extreme left or right and
remains there during normal driving, the electrical
system should be serviced.
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 pres-
sure when the engine is running. A continuous high
or low reading under normal driving conditions may
indicate a lubrication system malfunction. Immedi-
ate service should be obtained from an authorized
dealer.
4. Speedometer
• Indicates vehicle speed.
5. Fuel Gauge
• The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
• The fuel pump arrow symbol points to the
side of the vehicle where the fuel door is located. 4UNDERSTANDING YOUR INSTRUMENT PANEL 237

6. Driver Information Display (DID)
• When the appropriate conditions exist, this display
shows the Driver Information Display (DID) mes-
sages. Refer to “Driver Information Display (DID)”
in “Understanding Your Instrument Panel” for fur-
ther information.
7. 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 or up moun-
tain grades. It should not be allowed to exceed the
upper limits of the normal operating range. CAUTION!Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H”, turn the engine off immediately
and call an authorized dealer for service.
