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 thePARKSENSE UNAVAILABLE WIPE
REAR SENSORS, PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS,orthePARKSENSE UNAVAIL-
ABLE SERVICE REQUIRED message for five seconds.
When the shift lever is moved to Reverse and the system
has detected a faulted condition, the EVIC will display a
PARKSENSE UNAVAILABLE WIPE REAR SENSORS ,
PARKSENSE UNAVAILABLE WIPE FRONT SENSORS 
or PARKSENSE UNAVAILABLE SERVICE REQUIRED
pop up message for five seconds. After five seconds, a car
graphic will be displayed with UNAVAILABLEat ei-
ther 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 UNAVAIL-
ABLE WIPE REAR SENSORS, PARKSENSE UNAVAIL-
ABLE WIPE FRONT SENSORS,orPARKSENSE
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 Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
If PARKSENSE UNAVAILABLE WIPE REAR SENSORS
or PARKSENSE UNAVAILABLE WIPE FRONT SEN-
SORS appears in the Electronic Vehicle Information
Center (EVIC) make sure the outer surface and the

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.
• Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense®. •
When you turn ParkSense® off, the instrument cluster
will display “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 shift lever to the REVERSE
position and ParkSense® is turned off, the instrument
cluster will display “PARKSENSE OFF” 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 objects such as bicycle carriers, trailer
hitches, etc. are placed within 12 in (30 cm) from the
rear fascia/bumper. Failure to do so can result in the
system misinterpreting a close object as a sensor
problem, causing the “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message to be displayed in the
instrument cluster.
• 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 indication that an obstacle is behind the vehicle.
• There may be a delay in the object detection rate if the
object is moving. This will cause the automatic braking
application to be delayed.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.
• 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.

WARNING! (Continued)
•Before using ParkSense®, it is strongly recom-
mended that the ball mount and hitch ball assem-
bly is disconnected from the vehicle when the
vehicle is not used for towing. Failure to do so can
result in injury or damage to vehicles or obstacles
because the hitch ball will be much closer to the
obstacle than the rear fascia when the loudspeaker
sounds the continuous tone. Also, the sensors
could detect the ball mount and hitch ball assem-
bly, depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
16. Electronic Vehicle Information Center (EVIC)
Display/Odometer Display
The odometer display shows the total distance the ve-
hicle has been driven. U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. If your
odometer needs to be repaired or serviced, the repair
technician should leave the odometer reading the same
as it was before the repair or service. If s/he cannot do so,
then the odometer must be set at zero, and a sticker must
be placed in the door jamb stating what the mileage was
before the repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/
service, so that you can be sure that it is properly reset, or
that the door jamb sticker is accurate if the odometer
must be reset at zero.
When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center (EVIC)
messages. Refer to “Electronic Vehicle Information Cen-
ter” of your owners manual for more information.

When this feature is selected, the Blind Spot Alert feature
Provides alerts, visual and/or audible, to indicate objects
in your blind spot. The Blind Spot Alert feature can be
activated in “Lights” mode. When this mode is selected,
the Blind Spot Monitor (BSM) system is activated and will
only show a visual alert in the exterior mirrors. When
“Lights & Chime” mode is activated, the Blind Spot
Monitor (BSM) will show a visual alert in the exterior
mirrors as well as an audible alert when the turn signal is
on. When “Off” is selected, the Blind Spot Monitor (BSM)
system is deactivated. To change the Blind Spot Alert
status, touch the “Off,” “Lights” or “Lights & Chime”
soft-key. Then touch the back arrow soft-key.
NOTE: If your vehicle has experienced any damage in
the area where the sensor is located, even if the fascia is
not damaged, the sensor may have become misaligned. Take your vehicle to an authorized dealer to verify sensor
alignment. Having a sensor that is misaligned will result
in the BSM not operating to specification.

Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly
set, the compass will automatically compensate for the
differences, and provide the most accurate compass
heading.
NOTE: Keep magnetic materials, such as iPod’s®,
Mobile Phones, Laptops and Radar Detectors, away from
the top of the instrument panel where the compass
module is located. These materials can cause interference
with the compass sensor, and it may give false readings.

WARNING!
Many factors, such as vehicle loading, road condi-
tions, and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM cannot
prevent all wheel lift or rollovers, especially those
that involve leaving the roadway or striking objects
or other vehicles. The capabilities of an ERM-
equipped vehicle must never be exploited in a reck-
less or dangerous manner, which could jeopardize
the user’s safety or the safety of others.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle
by applying the brake of the appropriate wheel to assist
in counteracting the oversteer or understeer condition.Engine power may also be reduced to help the vehicle
maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•
Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The “ESC Activation/Malfunction Indicator Light” lo-
cated in the instrument cluster will start to flash as soon
as the tires lose traction and the ESC system becomes
active. The “ESC Activation/Malfunction Indicator
Light” also flashes when the TCS is active. If the “ESC
