Be sure the hood is fully latched before driving
your vehicle. If the hood is not fully latched, it
could open when the vehicle is in motion and
block your vision. Failure to follow this warn-
ing could result in serious injury or death.
LIGHTS
Headlight Switch
The headlight switch is located on the left side
of the instrument panel, next to the steering
wheel. The headlight switch controls the opera-
tion of the headlights, parking lights, instrument
panel lights, cargo lights and fog lights (if
equipped).To turn on the headlights, rotate
the headlight switch clockwise.
When the headlight switch is on
the parking lights, taillights, li-
cense plate light and instrument
panel lights are also turned on. To
turn off the headlights, rotate the headlight
switch back to the O (Off) position.
NOTE:
• Your vehicle is equipped with plastic
headlight and fog light (if equipped)
lenses that are lighter and less suscep-
tible to stone breakage than glass lights. Plastic is not as scratch resistant as glass
and therefore different lens cleaning pro-
cedures must be followed.
• To minimize the possibility of scratching
the lenses and reducing light output,
avoid wiping with a dry cloth. To remove
road dirt, wash with a mild soap solution
followed by rinsing.
CAUTION!
Do not use abrasive cleaning components,
solvents, steel wool or other abrasive materi-
als to clean the lenses.
Automatic Headlights — If EquippedThis system automatically turns the headlights
on or off according to ambient light levels. To
turn the system on, rotate the headlight switch
to the A (AUTO) position.
When the system is on, the Headlight Delay
feature is also on. This means the headlights
will stay on for up to 90 seconds after you turn
the ignition switch to the OFF position. To turn
the automatic headlights off, turn the headlight
switch out of the AUTO position.

initiated when the ignition is turned OFF while
the headlight switch is on, and then the head-
light switch is cycled off. Headlight delay can
be cancelled by either turning the headlight
switch on then off, or by turning the ignition ON.
The headlight delay time is programmable on
vehicles equipped with an Electronic Vehicle
Information Center (EVIC). Refer to “Electronic
Vehicle Information Center (EVIC)/Customer-
Programmable Features” in “Understanding
Your Instrument Panel” for further information.
Parking Lights and Panel Lights
To turn on the parking lights and instru-
ment panel lights, rotate the headlight
switch clockwise. To turn off the park-
ing lights, rotate the headlight switch back to
the O (Off) position.
Front And Rear Fog Lights — If
Equipped
The front and rear fog lights may be operated
as desired when visibility is poor due to fog.
The fog lights will activate in the following order:
Press the headlight switch once and the front
fog lights come on. Press the switch a second time and the rear fog lights will come on (front
fog lights stay on). Press the switch a third time
and the rear fog lights turn off (front fog stays
on). Press the switch a fourth times and the
front fog turns off. For vehicles without front fog,
rear fog will activate on the first press.
NOTE:
The headlight switch must first be turned to
the position lights or headlights position
before the fog lamp switch can be pushed in.
Interior LightsCourtesy and dome lights are turned on when
the front doors are opened, when the dimmer
control (rotating wheel on the right side of the
headlight switch) is rotated to the its farthest
upward position, or if equipped, when the UN-
LOCK button is pressed on the Remote Keyless
Entry (RKE) transmitter. When a door is open
and the interior lights are on, rotating the dim-
mer control all the way down, to the OFF detent,
will cause all the interior lights to go out. This is
also known as the “Party” mode because it
allows the doors to stay open for extended
periods of time without discharging the vehi-
cle’s battery.
The brightness of the instrument panel lighting
can be regulated by rotating the dimmer con-
trol up (brighter) or down (dimmer). When the
headlights are on you can supplement the
brightness of the odometer, trip odometer, radio
and overhead console by rotating the control to
its farthest position up until you hear a click.
This feature is termed the “Parade” mode and
is useful when headlights are required during
the day.

than 30 mph (48 km/h), see your authorized
dealer as soon as possible to have the problem
diagnosed and corrected.
NOTE:
•The “ESC Off Indicator Light” and the
“ESC Activation/Malfunction Indicator
Light” come on momentarily each time
the ignition switch is turned to ON/RUN.
• Each time the ignition is turned to ON/
RUN, the ESC system will be ON, even if it
was turned off previously.
• The ESC system will make buzzing or
clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation.
5. TOW/HAUL Indicator Light — If
Equipped This light will illuminate when the
TOW/HAUL button has been se-
lected. The TOW/HAUL button is
located in the center of the instru-
ment panel (below the climate
controls). 6. Turn Signal Indicator
The arrows will flash with the exterior turn
signals when the turn signal lever is op-
erated. A tone will chime, and an EVIC
message will appear if the turn signals are left
on for more than 1 mile (1.6 km).
NOTE:
Check for an inoperative outside light bulb if
either indicator flashes at a rapid rate.
7. High Beam Indicator Indicates that headlights are on high
beam.
8. Front Fog Light Indicator — If Equipped This indicator will illuminate when the
front fog lights are on.
9. Hill Descent Control Indicator Light — If
Equipped The symbol indicates the status of
the Hill Decent Control (HDC) fea-
ture. The lamp will be on solid
when HDC is armed. HDC can
only be armed when the transfer
case is in the “4WD Low” position and the vehicle speed is less then 30 mph
(48 km/h). If these conditions are not met while
attempting to use the HDC feature, the HDC
indicator lamp will flash on/off.
10. Electronic Vehicle Information Center
(EVIC) Display/Odometer Display
The odometer display shows the total distance
the vehicle has been driven.
When the appropriate conditions exist, this
display shows the Electronic Vehicle Informa-
tion Center (EVIC) messages. Refer to “Elec-
tronic Vehicle Information Center”.
11. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recom-
mended by the vehicle manufac-
turer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)

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.

•Anytime you store your vehicle, or keep it out
of service (i.e. vacation) for two weeks or
more, run the air conditioning system at idle
for about five minutes in the fresh air and
high blower setting. This will ensure ad-
equate system lubrication to minimize the
possibility of compressor damage when the
system is started again.

(HID) – If Equipped
The headlamps are a type of high voltage
discharge tube. High voltage can remain in the
circuit even with the headlamp switch off and
the key removed.
Because of this, you should
not attempt to service a headlamp bulb your-
self. If a headlamp bulb fails, take your
vehicle to an authorized dealer for service.
