Defroster
Check operation by selecting the defrost mode
and place the blower control on high speed.
You should be able to feel the air directed
against the windshield. See your authorized
dealer for service if your defroster is inoper-
able.
Floor Mat Safety Information
Always use floor mats designed to fit the foot-
well of your vehicle. Use only floor mats that
leave the pedal area unobstructed and that are
firmly secured so that they cannot slip out of
position and interfere with the pedals or impair
safe operation of your vehicle in other ways.WARNING!
Pedals that cannot move freely can cause
loss of vehicle control and increase the risk of
serious personal injury.
•Always make sure that floor mats are prop-
erly attached to the floor mat fasteners.
• Never place or install floor mats or other
floor coverings in the vehicle that cannot be
properly secured to prevent them from
moving and interfering with the pedals or
the ability to control the vehicle.
• Never put floor mats or other floor cover-
ings on top of already installed floor mats.
Additional floor mats and other coverings
will reduce the size of the pedal area and
interfere with the pedals.
(Continued)WARNING!(Continued)
• Check mounting of mats on a regular basis.
Always properly reinstall and secure floor
mats that have been removed for cleaning.
• Always make sure that objects cannot fall
into the driver footwell while the vehicle is
moving. Objects can become trapped un-
der the brake pedal and accelerator pedal
causing a loss of vehicle control.
• If required, mounting posts must be prop-
erly installed, if not equipped from the fac-
tory.
Failure to properly follow floor mat installation
or mounting can cause interference with the
brake pedal and accelerator pedal operation
causing loss of control of the vehicle.

NOTE:
•The head restraints should only be re-
moved by qualified technicians, for ser-
vice purposes only. If either of the head
restraints require removal, see your au-
thorized dealer.
• In the event of deployment of an Active
Head Restraint, refer to “Occupant
Restraints/Resetting Active Head Re-
straints (AHR)” in “Things to Know Be-
fore Starting Your Vehicle” for further in-
formation.
WARNING!
•Do not place items over the top of the
Active Head Restraint, such as coats, seat
covers or portable DVD players. These
items may interfere with the operation of
the Active Head Restraint in the event of a
collision and could result in serious injury or
death.
(Continued)
WARNING!(Continued)
• Active Head Restraints may be deployed if
they are struck by an object such as a
hand, foot or loose cargo. To avoid acci-
dental deployment of the Active Head Re-
straint ensure that all cargo is secured, as
loose cargo could contact the Active Head
Restraint during sudden stops. Failure to
follow this warning could cause personal
injury if the Active Head Restraint is de-
ployed.
Head Restraints — Rear Seats
The head restraints on the outboard seats are
not adjustable. They automatically fold forward
when the rear seat is folded to a load floor
position but do not return to their normal posi-
tion when the rear seat is raised. After returning
either seat to its upright position, raise the head
restraint until it locks in place. The outboard
headrests are not removable.

To Raise Rear Seat
Raise the rear seatback and lock it into place. If
interference from the cargo area prevents the
seatback from fully locking, you will have diffi-
culty returning the seat to its proper position.
WARNING!
•Be certain that the seatback is securely
locked into position. If the seatback is not
securely locked into position the seat will
not provide the proper stability for child
seats and/or passengers. An improperly
latched seat could cause serious injury.
• The cargo area in the rear of the vehicle
(with the rear seatbacks in the locked-up or
folded down position) should not be used
as a play area by children when the vehicle
is in motion. They could be seriously in-
jured in a collision. Children should be
seated and using the proper restraint sys-
tem.
Reclining Rear SeatTo recline the seatback, lift the lever located on
the outboard side of the seat, lean back and
release the lever at the desired position. To
return the seatback, lift the lever, lean forward
and release the lever.
WARNING!
Do not ride with the seatback reclined so that
the shoulder belt is no longer resting against
your chest. In a collision you could slide under
the seat belt, which could result in serious
injury or death.
DRIVER MEMORY SEAT — IF
EQUIPPED

sunroof is detected, the sunroof will automati-
cally retract. Remove the obstruction if this
occurs. Next, press the switch forward and
release to Express Close.
NOTE:
If three consecutive sunroof close attempts
result in Pinch Protect reversals, the fourth
close attempt will be a Manual Close move-
ment with Pinch Protect disabled.
Venting Sunroof — ExpressPress and release the Vent button within one
half second and the sunroof will open to the
vent position. This is called “Express Vent”, and
it will occur regardless of sunroof position.
During Express Vent operation, any movement
of the switch will stop the sunroof.
Sunshade OperationThe sunshade can be opened manually. How-
ever, the sunshade will open automatically as
the sunroof opens.
NOTE:
The sunshade cannot be closed if the sun-
roof is open.
Wind BuffetingWind buffeting can be described as the per-
ception of pressure on the ears or a helicopter-
type sound in the ears. Your vehicle may exhibit
wind buffeting with the windows down, or the
sunroof (if equipped) is in certain open or
partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting
occurs with the rear windows open, open the
front and rear windows together to minimize the
buffeting. If the buffeting occurs with the sun-
roof open, adjust the sunroof opening to mini-
mize the buffeting or open any window.
Sunroof MaintenanceUse only a nonabrasive cleaner and a soft cloth
to clean the glass panel.

close attempt will be a Manual Close move-
ment with Pinch Protect disabled.
Pinch Protect OverrideIf a known obstruction (ice, debris, etc.) pre-
vents closing the sunroof, press the switch
forward and hold for two seconds after the
reversal occurs. This allows the sunroof to
move toward the closed position.NOTE:
Pinch protection is disabled while the
switch is pressed.
Wind BuffetingWind buffeting can be described as the per-
ception of pressure on the ears or a helicopter-
type sound in the ears. Your vehicle may exhibit
wind buffeting with the windows down, or the
sunroof (if equipped) in certain open or partially
open positions. This is a normal occurrence
and can be minimized. If the buffeting occurs
with the rear windows open, open the front and
rear windows together to minimize the buffet-
ing. If the buffeting occurs with the sunroof
open, adjust the sunroof opening to minimize
the buffeting or open any window.
Sunroof MaintenanceUse only a non-abrasive cleaner and a soft
cloth to clean the glass panel.
Ignition OFF OperationThe power sunroof switches can be pro-
grammed to remain active for up to approxi-
mately ten minutes after the ignition switch has
been turned OFF. Refer to “Electronic Vehicle

Retractable Cargo Area Cover — If
Equipped
NOTE:
The purpose of this cover is for privacy, not
to secure loads. It will not prevent cargo
from shifting or protect passengers from
loose cargo.
To cover the cargo area:
1. Grasp the cover at the center handle. Pull it
over the cargo area.
2. Insert the pins on the ends of the cover into
the slots in the pillar trim cover.
3. The liftgate may be opened with the cargo
cover in place.
WARNING!
In a collision, a loose cargo cover in the
vehicle could cause injury. It could fly around
in a sudden stop and strike someone in the
vehicle. Do not store the cargo cover on the
cargo floor or in the passenger compartment.
Remove the cover from the vehicle when
taken from its mounting. Do not store it in the
vehicle.
Cargo Tie-Down HooksThe cargo tie-downs, located on the cargo area
floor, should be used to safely secure loads
when the vehicle is moving.
WARNING!
•To help protect against personal injury,
passengers should not be seated in the
rear cargo area. The rear cargo space is
intended for load carrying purposes only,
not for passengers, who should sit in seats
and use seat belts.

desired position, retighten the with the wrench
to lock the crossbar into position.
NOTE:
•To help control wind noise when the
crossbars are not in use, place the front
and rear crossbars approximately 24 in
(61 cm) apart. Optimal noise reduction
can then be achieved by adjusting the
front crossbar forward or aft using incre-
ments of 1 in (2.5 cm).
• If the rear crossbar (or any metallic ob-
ject) is placed over the satellite radio
antenna (if equipped), you may experi-
ence interruption of satellite radio recep-
tion. For improved satellite radio recep-
tion, avoid placing the rear crossbar over
the satellite radio antenna.
• The grab handles on the back of the
vehicle (if equipped) are not to be used as
a towing feature.CAUTION!
•To prevent damage to the roof of your
vehicle, do not carry any loads on the roof
rack without the crossbars installed. The
load should be secured and placed on top
of the crossbars, not directly on the roof. If
it is necessary to place the load on the roof,
place a blanket or some other protection
between the load and the roof surface.
• To avoid damage to the roof rack and
vehicle, do not exceed the maximum roof
rack load capacity of 150 lbs (68 kg).
Always distribute heavy loads as evenly as
possible and secure the load appropriately.
• Long loads which extend over the wind-
shield, such as wood panels or surfboards,
or loads with large frontal area should be
secured to both the front and rear of the
vehicle.
(Continued)CAUTION!(Continued)
• Travel at reduced speeds and turn corners
carefully when carrying large or heavy
loads on the roof rack. Wind forces, due to
natural causes or nearby truck traffic, can
add sudden upward lift to a load. This is
especially true on large flat loads and may
result in damage to the cargo or your
vehicle.
WARNING!
Cargo must be securely tied before driving
your vehicle. Improperly secured loads can fly
off the vehicle, particularly at high speeds,
resulting in personal injury or property dam-
age. Follow the roof rack cautions when car-
rying cargo on your roof rack.

23. Electronic Stability Control (ESC) OFF
Indicator Light — If EquippedThis light indicates the Electronic
Stability Control (ESC) is off.
24. Vehicle Security Light This light will flash rapidly for ap-
proximately 15 seconds when the
vehicle theft alarm is arming. The
light will flash at a slower speed
continuously after the alarm is set.
The security light will also come on
for about three seconds when the ignition is first
turned on.
25. Temperature Gauge
The temperature gauge shows engine coolant
temperature. Any reading within the normal
range indicates that the engine cooling system
is operating satisfactorily.
The gauge pointer will likely indicate a higher
temperature when driving in hot weather, up
mountain grades, or when towing a trailer. It should not be allowed to exceed the upper
limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature
gauge reads “H” pull over and stop the ve-
hicle. Idle the vehicle with the air conditioner
turned off until the pointer drops back into the
normal range. If the pointer remains on the “H”
and you hear continuous chimes, turn the
engine off immediately and call an authorized
dealership for service.
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by steam
or boiling coolant. You may want to call an
authorized dealership for service if your ve-
hicle overheats. If you decide to look under
the hood yourself, see “Maintaining Your Ve-
hicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.26. Rear Fog Light Indicator
This indicator will illuminate when the
rear fog lights are on.
