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”.

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.

non-essential electrical devices or increase en-
gine speed (if at idle). If the charging system
light remains on, it means that the vehicle is
experiencing a problem with the charging sys-
tem. Obtain SERVICE IMMEDIATELY. See an
authorized dealer.
If jump starting is required, refer to “Jump
Starting Procedures” in “What To Do In Emer-
gencies”.
•Electronic Throttle Control (ETC) Light
This light informs you of a problem
with the Electronic Throttle Control
(ETC) system. The light will come
on when the ignition is first turned

check. If the light does not come
on during starting, have the system checked by
an authorized dealer.
If a problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped
and the shift lever is placed in the PARK
position. The light should turn off.
If the light remains lit with the engine running
your vehicle, will usually be drivable, however, see an authorized dealer for service as soon as
possible. If the light is flashing when the engine
is running, immediate service is required and
you may experience reduced performance, an
elevated/rough idle or engine stall and your
vehicle may require towing.
•
Engine Temperature Warning Light
This light warns of an overheated en-
gine condition. As temperatures rise
and the gauge approaches H,this
indicator will illuminate and a single
chime will sound after reaching a set threshold.
Further overheating will cause the temperature
gauge to pass H,the indicator will continuously
flash and a continuous chime will occur until
the engine is allowed to cool.
If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is
on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the tempera-
ture reading does not return to normal, turn the
engine off immediately and call for service.
Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for more information. •
Transmission Temperature Light
This light indicates that there is
excessive transmission fluid tem-
perature that might occur with se-
vere usage such as trailer towing.
It may also occur when operating
the vehicle in a high torque con-
verter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road opera-
tion). If this light comes on, stop the vehicle and
run the engine at idle or faster, with the trans-
mission in NEUTRAL until the light goes off.
CAUTION!
Continuous driving with the Transmission
Temperature Indicator illuminated will eventu-
ally cause severe transmission damage or
transmission failure.

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-

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.
