INSTRUMENT CLUSTER DESCRIPTION
Your vehicle is equipped with the instrument cluster
described on the following pages.
1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank. When
the fuel gauge pointer initially moves to E, for your
safety, approximately 2 U.S. Gallons (7.6L) of fuel remain.
NOTE:When the ignition switch is turned to OFF, the
fuel gauge, voltmeter, oil pressure and temperature
gauges may not show accurate readings. When the
engine is not running, turn the ignition switch to ON to
obtain accurate readings.
2. Charging System Warning Light
This light shows the status of the electrical charg-
ing system. The light should come on for three
seconds when the ignition is first turned ON. If the light
comes back on immediately or comes on while driving, it
means that there is a problem with the charging systemor the battery is low. Also, a chime will sound if the light
comes back on. See your authorized dealer immediately.
3. Front Fog Light Indicator Light — If Equipped
This light shows when the front fog lights are on.
4. Low Fuel Warning Light
When the fuel level reaches approximately 2 U.S.
Gallons (7.6L) this light will come on and remain on
until fuel is added. The “Low Fuel Warning Light”
may turn on and off again, especially during and after
hard braking, accelerations, or turns. This occurs due to
the shifting of the fuel in the tank.

buckled, the chime will stop, but the light will stay
on until it times out (about 6 seconds).
8. Turn Signal Indicator Lights
The arrows will flash with the exterior turn signals
when the turn signal lever is operated. A tone will
chime if the turn signals are left on for more than 1 mile
(2 km).
9. Oil Pressure Warning Light
Shows low engine oil pressure. The light will come
on and remain on when the ignition switch isturned from the OFF to the ON position, and the light
will turn off after the engine is started. If the bulb does
not come on, have the system checked by your autho-
rized dealer.

24. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.
U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so the correct mileage can be
determined.
25. Malfunction Indicator Light
This light is a part of an Onboard Diagnostic
System called OBD II that monitors engine, and
automatic transmission control systems. The light
will illuminate when the ignition is in the ON position
before engine start. If the bulb does not come on when
turning the key from OFF to ON, have the condition
checked promptly.Certain conditions such as a loose or missing gas cap,
poor quality fuel, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving styles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the “Malfunction Indicator
Light” may flash to alert serious conditions that could
lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs.
26. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light
This indicator light starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The “ESP/TCS Indicator Light” also
flashes when TCS is active. If the “ESP/TCS
Indicator Light” begins to flash during acceleration, ease
208 UNDERSTANDING YOUR INSTRUMENT PANEL

up on the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and driving to the
prevailing road conditions. The “ESP/TCS Indicator
Light” will flash any time the ESP or TCS is active and
helping to improve vehicle stability. If the “ESP/TCS
Indicator Light” is on solid, the ESP system has been
turned off by the driver or a temporary condition exists
that will not allow full ESP function.
27. O/D (Overdrive) Off Indicator Light
This light will illuminate when the O/D OFF
button has been selected. The O/D OFF button is
located on the gear shift lever.
28. Sway Bar Indicator Light — If Equipped
This light will illuminate when the front sway
bar is disconnected.29. Electronic Stability Program (ESP) Warning
Light/Brake Assist System (BAS) Warning Light
The ESP/BAS warning light in the instrument
cluster comes on when the ignition switch is
turned to the “ON” position. The light should
go out with the engine running. If the ESP/
BAS warning light comes on continuously with the
engine running, a malfunction has been detected in either
the ESP or the BAS system. If this light stays illuminated,
have the ESP and BAS checked at your authorized dealer
as soon as possible. Refer to “Electronic Brake Control
System” in Section 5 for more information.

30. Electronic Throttle Control (ETC) Warning Light —
If Equipped
This light informs you of a problem with the
Electronic Throttle Control System. If a prob-
lem is detected while the engine is running, the
light will either stay on or flash depending on
the nature of the problem. Cycle the ignition key when
the vehicle is safely and completely stopped and the gear
selector is placed in the P (Park) position. The light
should turn off. If the light remains on with the engine
running, your vehicle will usually be drivable, however,
see your dealer for service as soon as possible.
If the light continues to flash 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. The light will
come on when the ignition is first turned on and remainon briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.
31. Compass/Mini-Trip Computer Display — If

After initial calibration, the compass will continue to
automatically update this calibration whenever the ve-
hicle is in motion.
Manual Compass Calibration
NOTE: Before attempting a manual compass calibra-
tion, the engine must be running and the transmission
in the P (Park) position (if equipped).
Compass calibration can also be requested. To manually
calibrate the compass, you must first enter the variance
mode. Press the and hold the left button (located on the
instrument cluster) for approximately 10 seconds to enter
the variance mode, and release the button when the VAR
symbol appears. The current variance value will also be
displayed. Once in the variance mode, it is necessary to
release the button, and then press and hold it again
(approximately 10 seconds) until CAL is displayed (solid
not blinking). Manual compass calibration has been
initiated. Drive the vehicle slowly in one or more circlesunder 5 mph (8 km/h) in an area free from large metal
objects until the CAL symbol is extinguished.
When the CAL symbol no longer is displayed, the
compass is calibrated and should display correct head-
ings. Verify proper calibration by checking North (N),
South (S), East (E), and West (W). If the compass does not
appear accurate, repeat the calibration procedure in an-
other area.
Compass Variance
Variance is the difference between magnetic North and
geographic North. For proper compass function, the
correct variance zone must be set.
Setting the Compass Variance
Refer to the variance map for the correct compass vari-
ance zone. To check the variance zone, the ignition must
be on. Press and hold the left button (located on the
instrument cluster) for approximately 10 seconds to enter
the variance mode and release the button when the VAR

moisture build up inside the vehicle. For maximum
defogging, select the Outside Air position.
NOTE:The “Recirculate” mode will not operate in floor,
mix or defrost modes.

Operating Tips
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases
turning on the air-conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction 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
258 UNDERSTANDING YOUR INSTRUMENT PANEL

smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Fluids and
Genuine Parts in Section 7 for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift into
N (Neutral) and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
