than the other, the system will apply the brake of the
spinning wheel and allow more engine torque to be
applied to the wheel that is not spinning.
To improve the vehicle’s traction when driving with
snow chains, or starting off in deep snow, sand or gravel,
it may be desirable to switch off the ESP by pressing the
ESP switch.
With the ESP switched off, the engine torque reduction
and stability features are cancelled. Therefore, the en-
hanced vehicle stability offered by ESP is unavailable.
If the “ESP Indicator Light” begins to flash during
acceleration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions. When the “ESP
Indicator Light” is illuminated continuously, the ESP is
switched off. To return to the enhanced vehicle stability
offered by ESP, press the ESP switch (the “ESP IndicatorLight” in the instrument cluster goes out). Avoid spin-
ning one drive wheel. This may cause serious damage to
the drive train.
NOTE:
•The “ESP Indicator Light” comes on momentarily each
time the ignition switch is turned ON.
•Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
•The ESP Control System will make buzzing or clicking
sounds when it is active.
There are two Electronic Vehicle Information Center
(EVIC) messages associated with the Electronic Stability
Control System. Refer to Section 4 of this manual.
ESP System Disabled
This message will be displayed if the ESP System has
been turned off using the switch, or if there is a tempo-
rary condition that will result in partial or no ESP

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.
Rear Park Assist Display
128 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

When the ignition is changed to the RUN/ON position,
the warning display will turn ON all of its LEDs for
about 1 sec.
Each side of the warning display has 6 yellow and 2 red
LEDs. The vehicle is close to the obstacle when the red
LED is ON.
When the obstacle is detected at a distance of about 59
inches (150 cm) from the rear fascia, the outermost LEDs
of the warning display will be ON with increased bright-
ness. As the distance of the detected obstacle to the rear
fascia decreases, more LEDs are illuminated. The warn-
ing display will not actuate a tone when only yellow
LEDs are ON.
When the warning display has the first 7 LEDs ON,
including 1 red LED, the warning display will actuate an
intermittent tone for about 3 sec. The radio will be muted
while the tone is actuated.When the detected obstacle is about 11.8 inches (30 cm)
from the rear fascia, the warning display will actuate a
continuous tone for about 3 sec and it will turn ON all 8
LEDs, including both RED LEDs, on the corresponding
side of the display. The radio will be muted while the
tone is actuated.
When the obstacle is less than 11.8 inches (30 cm) from
the rear fascia, the warning display will either have all 8
LEDs ON (obstacle detected) or it will have only the
outermost LEDs ON with decreased brightness (obstacle
not detected), depending on the location of the 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.
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 131

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.
132 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

rearward (toward the driver).
Press the right side of the button to move the pedals
forward (away from the driver).
•The pedals can be adjusted with the ignition OFF.
•The pedals can be adjusted while driving.
•The pedalscannotbe adjusted when the vehicle is in R
(Reverse) or when the Speed Control is ON. A message
will be displayed in the Electronic Vehicle Information
Center (EVIC) if the pedals are attempted to be ad-
justed when the system is locked out (“Adjustable
Pedal Disabled — Cruise Control Engaged” or “Ad-
justable Pedal Disabled — Vehicle In Reverse”). Refer
to Electronic Vehicle Information Center (EVIC) in
Section 4 for more information.
CAUTION!
Do not place any article under the adjustable pedal’s
or impede its ability to move as it may cause damage
to the pedal controls. Pedal travel may become
limited if movement is stopped by an obstruction in
the adjustable pedal’s path.
