REAR PARK ASSIST SYSTEM — IF EQUIPPED
The Rear Park Assist System is a driver aid that senses for
obstacles behind the vehicle. Refer to the Warnings,
Cautions, and Notes in this section for system limitations
and usage recommendations.
The Rear Park Assist System is active when the driver
shifts the transmission into the “R” (Reverse) position,
and the parking brake is not applied, and the vehicle
speed is less than 10 mph (16 km/h).When the vehicle is in PARK, the system can be turned on
or off through the Electronic Vehicle Information Center
(EVIC) — if equipped. For details, refer to “Personal
Settings (Customer Programmable Features)” under
“Electronic Vehicle Information Center (EVIC)” in Sec-
tion 4 of this manual.
The system uses four sensors located in the rear bumper
to scan for obstacles up to 59 inches (150 cm) away from
the rear bumper fascia. The warning display located
above the rear window provides both visible and audible
warnings to indicate the range of the object.

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 ve-
hicles, 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.
•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 obstacles
because the hitch ball will be much closer to the
obstacle than the rear fascia when the warning dis-
play turns the red LEDs ON. Also, the sensors could
detect the ball mount and hitch ball assembly, de-
pending on its size and shape, giving a false indica-
tion that an obstacle is behind the vehicle.
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.

When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replace-
ment or alternate tires and wheels allow the TPMS to
continue to function properly. (See page 355 for more
information.)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 aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
23. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should turn on when the
ignition switch is first turned ON and remain on briefly
as a bulb check. If the light stays on or turns on while

Compass Variance
Compass Variance is the difference between magnetic
North and Geographic North. In some areas of the
country, the difference between magnetic and geographic
North is great enough to cause the compass to give false
readings. If this occurs, the compass variance must be set
using the following procedure:
NOTE:Magnetic materials should be kept away from
the overhead console. This is where the compass sensor is
located.

the controls on the climate control, from a dual sun-
sensor located in the top of the instrument panel, from an
infrared sensor located in the face of the climate control,
and from various sensors located throughout the vehicle.
The controls on the climate control provide the system
with operator input. The dual sun-sensor monitors sun
load coming through the windshield. The infrared sensor
independently measures the surface temperature of the
driver and passenger. Other sensors take account of
vehicle-speed, A/C pressure, outside temperature, and
engine cooling temperature. Using all of these inputs, the
system automatically adjusts airflow temperature, air-
flow distribution, airflow volume, and the amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.
Operation of the system is quite simple. Begin by turning
the Mode Control knob (on the right) to AUTO, and place
the Blower Control knob (on the left) to either LO AUTOor HI AUTO. The LO AUTO position should be used for
front seat occupants only. The HI AUTO position should
be used when more airflow is desired, or when rear seat
occupants are present. Then, dial in the temperature you
would like the system to maintain by rotating the driver
or passenger Temperature Control knob. Once the com-
fort level is selected, the system will maintain that level
automatically using the heating system. Should the de-
sired comfort level require air conditioning, the system
will automatically make the adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the OFF position on the fan control stops the system
completely and closes the outside air intake.
72°F (22°C) is the recommended setting for maximum
comfort for the average person; however, this may vary.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic operation.

Air conditioning in this system is automatic.
Pressing the Air Conditioning Control button
while in AUTO mode will cause the LED in the
control button to flash three times and then turn off. This
indicates that the system is in AUTO mode and request-
ing the air conditioning is not necessary.
The system will automatically control recircu-
lation. However, pressing the Recirculation
Control button will temporarily put the system
in recirculation mode (ten minutes). This can
be used when outside conditions such as smoke, odors,
dust, or high humidity are present. Activating recircula-
tion will cause the LED in the control button to illumi-
nate. After ten minutes, the system will return to normal
AUTO mode function and the LED will turn off.NOTE:
•The surface of the climate control panel and the top
center of the instrument panel should be kept free of
debris due to the location of the climate control
sensors. Mud on the windshield may also cause poor
operation of this system.
•Extended use of recirculation may cause the windows
to fog. If the interior of the windows begins to fog,
press the Recirculation button to return to outside air.
Some temp/humidity conditions will cause captured
interior air to condense on windows and hamper
visibility. For this reason, the system will not allow
Recirculation to be selected while in defrost or
defrost/floor mode. Attempting to use the recircula-
tion while in these modes will cause the LED in the
control button to blink and then turn off.

ELECTRONIC STABILITY PROGRAM (ESP) —
IF EQUIPPED
WARNING!
The ESP (Electronic Stability Program) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. The ESP cannot prevent
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ESP-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopar-
dize the user’s safety or the safety of others.This system enhances directional control and stability of
the vehicle under various driving conditions. The ESP
corrects for oversteering and understeering the vehicle
by applying the brake of the appropriate wheel. Engine
power may also be reduced to assist in counteracting the
condition of oversteer or understeer and help the vehicle
maintain the desired path.
The ESP uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESP applies the
brake of the appropriate wheel to assist in counteracting
the condition of oversteer or understeer.
•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.

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
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the Tire Pressure Moni-
toring Telltale light.
