•If the liftgate handle is pulled while the power liftgate
is opening, the liftgate motor will disengage to allow
manual operation.
•If the power liftgate encounters multiple obstructions
within the same cycle, the system will automatically
stop and the liftgate must be opened or closed manu-
ally.
•If your liftgate is power closing and you put the
vehicle in gear, the liftgate will continue to power
close. However, vehicle movement may result in a
detection of an obstruction.
WARNING!
•Driving with the liftgate open can allow poison-
ous exhaust gases into your vehicle. You and your
passengers could be injured by these fumes. Keep
the liftgate closed when you are operating the
vehicle.
•If you are required to drive with the liftgate open,
make sure that all windows are closed, and the
climate control blower switch is set at high speed.
Do not use the recirculation mode.
Gas props support the liftgate in the open position.
However, because the gas pressure drops with tempera-
ture, it may be necessary to assist the props when
opening the liftgate in cold weather.

•If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set
the blower at high speed.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.

Front Heated Seats
There are two heated seat switches that allow the driver
and passenger to operate the seats independently. The
controls for each heater are located near the bottom
center of the instrument panel (below the climate con-
trols).
You can choose from HIGH, LOW or OFF heat settings.
Amber indicator lights in each switch indicate the level of
heat in use. Two indicator lights will illuminate for
HIGH, one for LOW and none for OFF.Press the switch once to select HIGH-level
heating. Press the switch a second time to select
LOW-level heating. Press the switch a third
time to shut the heating elements OFF. NOTE:
Once a heat setting is selected, heat will be felt
within two to five minutes.
When the HIGH-level setting is selected, the heater will
provide a boosted heat level during the first four minutes
of operation. Then, the heat output will drop to the
normal HIGH-level. If the HIGH-level setting is selected,
the system will automatically switch to LOW-level after a
maximum of 50 minutes of continuous operation. At that
time, the number of illuminated LEDs changes from two
to one, indicating the change. The LOW-level setting will
turn OFF automatically after a maximum of 45 minutes.
Rear Heated Seats
On some models, the two outboard seats are equipped
with heated seats. There are two heated seat switches that
allow the rear passengers to operate the seats indepen-
dently. The heated seat switches for each heater are
located on the rear of the center console.

Ventilated Seats — If Equipped
On some models, both the driver and passenger seats are
ventilated. Located in the seat cushion and seatback are
small fans that draw the air from the passenger compart-
ment and blow air through fine perforations in the seat
cover to help keep the driver and front passenger cooler
in higher ambient temperatures.
There are two ventilated seat switches that allow the
driver and passenger to operate the seats independently.
The ventilated seat switches are located on the switch
bank in the center stack of the instrument panel, just
below the climate controls.The ventilated seat switches are used
to control the speed of the fans located
in the seat. Press the switch once to
choose HIGH, press it a second time to
choose LOW. Pressing the switch a
third time will turn the ventilated seat OFF. When HIGH speed is selected both lights on the
switch will be illuminated. When LOW speed is selected
one light will be illuminated.
NOTE:
The engine must be running for the ventilated
seats to operate.
Vehicles Equipped With Remote Start
On models that are equipped with remote start, the
driver’s ventilated seat can be programmed to come on
during a remote start. Refer to “Remote Starting System
— If Equipped” in “Things To Know Before Starting Your
Vehicle” for further information.
Head Restraints
Head restraints are designed to reduce the risk of injury
by restricting head movement in the event of a rear-
impact. Head restraints should be adjusted so that the top
of the head restraint is located above the top of your ear.

steering column is locked before driving your ve-
hicle. Failure to follow this warning may result in
serious injury or death.
HEATED STEERING WHEEL — IF EQUIPPED
The steering wheel contains a heating element that helps
warm your hands in cold weather. The heated steering
wheel has only one temperature setting. Once the heated
steering wheel has been turned on it will operate for
approximately 58 to 70 minutes before automatically
shutting off. The heated steering wheel can shut off early
or may not turn on when the steering wheel is already
warm.
The heated steering wheel switch is located on the switch
bank below the climate controls.
Press the switch to turn on the heated
steering wheel. The light on the switch
will illuminate to indicate the steering
wheel heater is on. Pressing the switch

The power inverter is designed with built-in overload
protection. If the power rating of 150 Watts is exceeded,
the power inverter will automatically shut down. Once
the electrical device has been removed from the outlet the
inverter should automatically reset. If the power rating
exceeds approximately 170 Watts, the power invertermay have to be reset manually. To reset the inverter
manually press the power inverter button OFF and ON.
To avoid overloading the circuit, check the power ratings
on electrical devices prior to using the inverter.
The power inverter switch is located
on the switch bank below the Climate
Controls. To turn on the power outlet,
press the switch once. Press the switch
a second time to turn the power outlet
off.
NOTE: When the power inverter switch is pressed,
there will be a delay of approximately one second before
the inverter status indicator turns ON. The status indica-
tor of the AC power inverter indicates whether the
inverter is producing AC power.

Rotate the center portion of the lever upward to the
first detent for intermittent operation and to the
second detent for continuous rear wiper operation.
Rotating the center portion upward once more will
activate the washer pump which will continue to
operate as long as the switch is held. Upon release
of the switch, the wipers will resume the continuous rear
wiper operation. When this rotary control is in the OFF
position, rotating it downward will activate the rear
washer pump which will continue to operate as long as
the switch is held. Once the switch is released it will
return to the OFF position and the wipers will cycle
several times before returning to the parked position.
NOTE: As a protective measure, the pump will stop if
the switch is held for more than 20 seconds. Once the
switch is released the pump will resume normal opera-
tion. If the rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the “park”
position.
If the liftgate flipper glass is open, the rear window
wiper/washer functionality is interrupted and the wiper
stops at that “park” position. When the liftgate flipper
glass is closed, the rear wiper will resume wiper/washer
functionality after five seconds.
Rear Window Defroster
The rear window defroster button is located on the
climate control panel. Press this button to turn on
the rear window defroster and the heated outside mirrors
(if equipped). An indicator in the button will illuminate
when the rear window defroster is on. The rear window
defroster automatically turns off after approximately
10 minutes. For an additional five minutes of operation,
press the button a second time.
