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).
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.
Regulations require that upon transfer of ve-
hicle ownership, the seller certify to the pur-
chaser the correct mileage that the vehicle has
been driven. If your odometer needs to be
repaired or serviced, the repair technician
should leave the odometer reading the same as
it was before the repair or service. If s/he
cannot do so, then the odometer must be set at
zero, and a sticker must be placed in the door
jamb stating what the mileage was before the
repair or service. It is a good idea for you to
make a record of the odometer reading before
the repair/service, so that you can be sure that
it is properly reset, or that the door jamb sticker
is accurate if the odometer must be reset at
zero.
When the appropriate conditions exist, this
display shows the Electronic Vehicle Informa-
tion Center (EVIC) messages. Refer to “Elec-
tronic Vehicle Information Center”.

13. Seat Belt Reminder LightWhen the ignition switch is first turned
to ON/RUN, this light will turn on for
four to eight seconds as a bulb check.
During the bulb check, if the driver or
front passenger’s seat belt is unbuckled, a
chime will sound. After the bulb check or when
driving, if the driver or front passenger seat belt
remains unbuckled, the Seat Belt Indicator
Light will flash or remain on continuously. Refer
to “Occupant Restraints” in “Things To Know
Before Starting Your Vehicle” for further infor-
mation.
14. Brake Warning Light This light monitors various brake
functions, including brake fluid
level and parking brake applica-
tion. If the brake light turns on, it
may indicate that the parking
brake is applied, that the brake
fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake
has been disengaged, and the fluid level is at
the full mark on the master cylinder reservoir, it
indicates a possible brake hydraulic system malfunction or that a problem with the Brake
Booster has been detected by the Anti-Lock
Brake System (ABS) / Electronic Stability Pro-
gram (ESP) system. In this case, the light will
remain on until the condition has been cor-
rected. If the problem is related to the brake
booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be
felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in either
half of the dual brake system is indicated by the
Brake Warning Light, which will turn on when
the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during
sharp cornering maneuvers, which change
fluid level conditions. The vehicle should
have service performed, and the brake fluid
level checked.
If brake failure is indicated, immediate repair is
necessary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may
have failed. It will take longer to stop the
vehicle. You could have a collision. Have the
vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake
System (ABS), are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is re-
quired.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the
OFF position to the ON/RUN position. The light
should illuminate for approximately two sec-
onds. The light should then turn off unless the
parking brake is applied or a brake fault is
detected. If the light does not illuminate, have
the light inspected by an authorized dealer.

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.

hair, moisture or dew on the disc) oversized,
or have protection encoding. Try a known
good disc before considering disc player
service.
RADIO OPERATION AND MOBILE
PHONES
Under certain conditions, the mobile phone
being on in your vehicle can cause erratic or
noisy performance from your radio. This condi-
tion may be lessened or eliminated by relocat-
ing the mobile phone antenna. This condition is
not harmful to the radio. If your radio perfor-
mance does not satisfactorily “clear” by the
repositioning of the antenna, it is recom-
mended that the radio volume be turned down

Mode Control (Air Direction)
Push the mode control buttons to choose from
several patterns of air distribution.
PanelAir is directed through the outlets in the
instrument panel. These outlets can be
adjusted to direct airflow.
NOTE:
The center instrument panel outlets can be
aimed so that they are directed toward the
rear seat passengers for maximum airflow
to the rear.
Bi-Level Air is directed through the panel and
floor outlets.
NOTE:
For all settings except full cold or full hot,
there is a difference in temperature between
the upper and lower outlets. The warmer air
flows to the floor outlets. This feature gives
improved comfort during sunny but cool
conditions. Floor
Air is directed through the floor outlets
with a small amount flowing through the
defrost and side window demist outlets.
Mix Air is directed through the floor, defrost,
and side window demist outlets. This
setting works best in cold or snowy
conditions that require extra heat to the
windshield. This setting is good for maintaining
comfort while reducing moisture on the wind-
shield.
Defrost Air is directed through the windshield
and side window demist outlets. Use
this mode with maximum blower and
temperature settings for best windshield and
side window defrosting.
NOTE:
• In Floor, Mix and Defrost modes a small
amount of air will flow through the out-
board panel outlets for occupant comfort.
• The air conditioning compressor oper-
ates in Mix, Defrost, or a blend of these
modes, even if the Air Conditioning (A/C) button is not pressed. This dehumidifies
the air to help dry the windshield. To
improve fuel economy, use these modes
only when necessary.
Recirculation Control Pressing the Recirculation Control
button will put the system in recir-
culation mode. This can be used
when outside conditions such as
smoke, odors, dust, or high humid-
ity are present. Activating recircu-
lation will cause the LED in the control button to
illuminate.
NOTE:
• Continuous use of the recirculation mode
may make the inside air stuffy and win-
dow fogging may occur. Extended use of
this mode is not recommended.
• The use of the recirculation mode in cold
or damp weather could cause windows to
fog on the inside, because of moisture
buildup inside the vehicle. Select the Out-
side Air position for maximum defogging.
• The A/C will engage automatically to pre-
vent fogging when the recirculation but-
187

ton is pressed and the mode control is set
to panel or panel / floor.

Automatic Temperature Control (ATC) Panel
188

NOTE:
In many temperature positions, the BI-
LEVEL mode is designed to provide cooler
air out of the panel outlets and warmer air
from the floor outlets.
Floor Mode
Air comes from the floor outlets. A slight
amount of air is directed through the
defrost and side window demister outlets.
Mix ModeAir comes from the floor, defrost and
side window demist outlets. This mode
works best in cold or snowy conditions.
It allows you to stay comfortable while
keeping the windshield clear.
Defrost Mode Air comes from the windshield and side
window demist outlets. Use Defrost
mode with maximum temperature set-
tings for best windshield and side window
defrosting. When the defrost mode is selected,
the blower will automatically default to medium-
high unless the blower is controlled manually. NOTE:
While operating in the other modes, the
system will not automatically sense the
presence of fog, mist or ice on the wind-
shield. Defrost mode must be manually se-
lected to clear the windshield and side
glass.
Air Conditioning (A/C)
The Air Conditioning (A/C) button allows the
operator to manually activate or deactivate the
air conditioning system. When in A/C mode and
the ATC is set to a cool temperature, dehumidi-
fied air flows through the air outlets. If Economy
mode is desired, press the A/C button to turn
off the A/C mode in the ATC display and
deactivate the A/C system.
NOTE:
•
If the system is in Mix, Floor or Defrost
Mode, the A/C can be turned off, but the
A/C system shall remain active to prevent
fogging of the windows.
• If fog or mist appears on the windshield or
side glass, select Defrost mode and in-
crease blower speed. Recirculation Control
When outside air contains smoke,
odors, or high humidity, or if rapid
cooling is desired, you may wish to
recirculate interior air by pressing
the RECIRCULATION control but-
ton. Recirculation mode should
only be used temporarily. The recirculation LED
will illuminate when this button is selected.
Push the button a second time to turn off the
Recirculation mode LED and allow outside air
into the vehicle.
NOTE:
In cold weather, use of Recirculation mode
may lead to excessive window fogging. The
Recirculation mode is not allowed in the
Floor/Defrost Mix and Defrost modes to im-
prove window clearing operation. Recircula-
tion will be disabled automatically if these
modes are selected.

Operating Tips
Window Fogging
Windows will fog on the inside when the humid-
ity inside the vehicle is high. This often occurs
in mild or cool temperatures when it’s rainy or
humid. In most cases, turning the air condition-
ing (pressing the A/C button) on will clear the
fog. Adjust the temperature control, air direc-
tion, and blower speed to maintain comfort.
As the temperature gets colder, it may be
necessary to direct air onto the windshield.
Adjust the temperature control and blower
speed to maintain comfort. Higher blower
speeds will reduce fogging. Interior fogging on
the windshield can be quickly removed by
selecting the DEFROST mode.Regular cleaning of the inside of the windows
with a non-filming cleaning solution (vinegar
and water works very well) will help prevent
contaminates (cigarette smoke, perfumes, etc.)
from sticking to the windows. Contaminates
increase the rate of window fogging.
Summer Operation
NOTE:
In some cases during high temperature
trailer tow operation the Air Conditioning
system performance may be reduced. This
is to help protect the engine from overheat-
ing during the high load condition.
Your air conditioning system is also equipped
with an automatic recirculation system. When
the system senses a heavy load or high heat
conditions, it may use partial Recirculation A/C
mode to provide additional comfort.Winter Operation
When operating the system during the winter
months, make sure the air intake, located di-
rectly in front of the windshield, is free of ice,
slush, snow, or other obstructions.
Vacation Storage
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 adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
