function. The “ESP Indicator Light” will be on when the
system is disabled or only partial function is allowed. The
“ESP SYSTEM DISABLED” message and the “ESP Indi-
cator Light” being illuminated without the switch being
depressed is not an indication that service of the elec-
tronic brake system is required.
Also, the “ESP SYSTEM DISABLED” message will be
present when the vehicle is shifted into 4WD LOW.
Service Elec Brake System
This message will be displayed if a condition exists that
may require servicing the electronic brake system. When
this message is displayed and the “ESP Indicator Light”
is on, there is a malfunction of the ESP System. If the
“SERVICE ELEC BRAKE SYSTEM” message continues to
be displayed after several ignition cycles and the vehicle
has been driven several miles at speeds greater than 30
mph (48 km/h), see your authorized dealer for service.CAUTION!
The manufacturer recommends towing with all four
wheels off the ground. Acceptable methods are to
tow the vehicle on a flatbed or with one end of the
vehicle raised and the other end on a towing dolly.
REAR PARK ASSIST SYSTEM— IF EQUIPPED
The Rear Park Assist System provides visual and audible
indications of the distance between the rear fascia and the
detected obstacle when backing up. Refer to the Warning
Section and Note Section for limitations of this system
and recommendations.
The Rear Park Assist System will remember the last
system state (enabled or disabled) from the last ignition
cycle when the ignition is changed to the RUN/ON
position.

The Rear Park Assist System can be active only when the
shifter is in R (Reverse). If the Rear Park Assist System is
enabled at this shifter position, the system will be active
until the vehicle speed is increased to approximately 11.2
miles/hr (18 km/h) or above. The system will be active
again if the vehicle speed is decreased to speeds less than
approximately 9.94 miles/hr (16 km/h).
Rear Park Assist Sensors
The four Rear Park Assist Sensors, located in the rear
fascia, monitor the area behind the vehicle that is within
the sensors’ field of view. The monitored area seems oval
in shape.
The sensors can detect obstacles from approximately 11.8
inches (30 cm) up to 59 inches (150 cm) from the rear
fascia in the horizontal direction, depending on the
location and orientation of the obstacle and the type of
obstacle.
Rear Park Assist Warning Display
The Rear Park Assist Warning Display, located in the
headliner near the flipper glass, provides both visual and
audible warnings to indicate the distance between the
rear fascia and the detected obstacle.

Enable/Disable the Rear Park Assist System
The Rear Park Assist System can be enabled and disabled
with a switch located in the switch bank of the instru-
ment panel.When the switch is pressed to disable the system, the
instrument cluster will display thePARK ASSIST DIS-
ABLEDmessage. Refer to Electronic Vehicle Information
Center (EVIC) in Section 4 of this manual. When the
shifter is changed to R (Reverse) and the system is
disabled, the instrument cluster will actuate a single
chime, once per ignition cycle, and it will display the
message.
The Rear Park Assist Switch LED will be ON when the
Rear Park Assist System is disabled or defective. The
Rear Park Assist Switch LED will be OFF when the
system is enabled.
Service the Rear Park Assist System
When the Rear Park Assist System is defective, the
instrument cluster will actuate a single chime, once per
ignition cycle, and it will display theSERVICE PARK
ASSIST SYSTEMmessage. Refer to Electronic Vehicle
Information Center (EVIC) in Section 4 of this manual.

Cleaning the Rear Park Assist System
Clean the Rear Park Assist 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.
CAUTION!
•The Rear Park Assist System is only a parking aid
and it is unable to recognize every obstacle, in-
cluding small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will not
be detected when they are in close proximity.
•The vehicle must be driven slowly when using the
Rear Park Assist System to be able to stop in time
when the obstacle is detected. It is recommended
that the driver looks over his/her shoulder when
using the Rear Park Assist System.
WARNING!
•Drivers must be careful when backing up even when
using the Rear Park Assist System. Always check
carefully behind your vehicle, look behind you, and
be sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before back-
ing up. You are responsible for safety and must
continue to pay attention to your surroundings. Fail-
ure to do so can result in serious injury or death.
•Before using the Rear Park Assist System, it is
strongly recommended that the ball mount and hitch
ball assembly 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 ob-
stacles because the hitch ball will be much closer to
the obstacle than the rear fascia when the warning
display turns the red LEDs ON. Also, the sensors
could detect the ball mount and hitch ball assembly,
depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.

NOTE:Clean all four Rear Park Assist 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 system might not detect an ob-
stacle behind the fascia or it could provide a false
indication that an obstacle is behind the fascia.
Assure objects are not within 11.8 inches (30 cm) from the
rear fascia while driving the vehicle. Failure to do so can
result in the system misinterpreting a close object as a
sensor problem, causing theSERVICE PARK ASSIST
SYSTEMmessage to be displayed in the instrument
cluster.Ultrasonic noise from airbrakes of nearby trucks, air
powered jackhammers and air powered shop tools, to
name a few, will cause the Rear Park Assist System to be
disabled until the ultrasonic noise is no longer present.
ADJUSTABLE PEDALS — IF EQUIPPED
This feature allows both the brake and accelerator pedals
to move toward the driver to provide improved position
with the steering wheel. The adjustable pedal system is
designed to allow a greater range of driver comfort for
steering wheel tilt and seat position. The position of the
brake and accelerator pedals can be adjusted without
compromising safety or comfort in actuating the pedals.

•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
•The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
