10. Oil Pressure Warning LightThis light indicates low engine oil pressure. The
light should turn on momentarily when the engine
is started. If the light turns on while driving, stop the
vehicle, and shut off the engine as soon as possible. A
continuous chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood.
11. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light If this indicator light flashes during accelera-
tion, apply as little throttle as possible. While
driving, ease up on the accelerator. Adapt your
speed and driving to the prevailing road con-
ditions, and do not switch off the Electronic Stability
Program (ESP), or Traction Control System (TCS). 12. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly, when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer 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.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
13. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily. The gauge pointer will likely indicate a higher tempera-
ture 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
240°F (116°C) or greater, pull over and stop the
vehicle. Idle the vehicle with the air conditioner
turned off until the pointer drops back into the
normal range 200–230°F (93–110°C). If the pointer
remains on the 240°F (116°C) or greater, 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 dealer-
ship for service if your vehicle overheats. If you
decide to look under the hood yourself, see “Main-
taining Your Vehicle”. Follow the warnings under the
Cooling System Pressure Cap paragraph.
14. Electronic Vehicle Information Center (EVIC)
Display
When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center (EVIC)
messages. Refer to “Electronic Vehicle Information Cen-
ter”. 15. Electronic Stability Program (ESP) Warning
Light/Brake Assist System (BAS) Warning Light — If
Equipped
The malfunction light for the Electronic Stabil-
ity Program (ESP) is combined with Brake
Assist System (BAS). The yellow “ESP/BAS
Warning Light” comes on when the ignition
switch is turned to the “ON” position. They 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 remains on after several ignition
cycles, and the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph (48 km/h), see
an authorized dealer as soon as possible.

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.
19. Shift Lever Indicator
The Shift Lever Indicator is self-contained within the
instrument cluster. It displays the gear position of the
automatic transmission.
NOTE:You must apply the brakes before shifting from
PARK.
20. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON position.
21. Electronic Throttle Control (ETC) Warning Light This light informs you of a problem with the
Electronic Throttle Control (ETC) system. 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 your
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. The light will come on
when the ignition is first turned on and remain on briefly
as a bulb check. If the light does not come on during
starting, have the system checked by an authorized
dealer.
22. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.

23. Charging System Light
This light shows the status of the electrical charging
system. The light should come on when the ignition
switch is first turned ON and remain on briefly as a bulb
check. If the light stays on or comes on while driving, turn
off some of the vehicle’s non-essential electrical devices or
increase engine speed (if at idle). If the charging system
light remains on, it means that the vehicle is experiencing
a problem with the charging system. Obtain SERVICE
IMMEDIATELY. See an authorized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.
24. Low Fuel Warning Light When the fuel level reaches approximately 2.3 U.S.
Gallons (8.7 Liters) 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.

COMPASS/TEMPERATURE button to dis-
play one of eight compass readings and the
outside temperature.
NOTE: The system will display the last known outside
temperature when starting the vehicle and may need to
be driven several minutes before the updated tempera-
ture is displayed. Engine temperature can also affect the
displayed temperature, therefore temperature readings
are not updated when the vehicle is not moving.
Automatic Compass Calibration
When the vehicle is new, the compass may appear erratic
and the EVIC will display “CAL” until the compass is
calibrated. To complete the calibration process, drive
slowly (5 mph/ 8 km/h) in one or more complete circles in an area, free from magnetic material until the CAL
indicator displayed in the EVIC turns off. The Compass
will now function normally.
Manual Compass Calibration

The system will automatically control re-
circulation. However, pressing this but-
ton will temporarily put the system in
“Recirculation” mode. This can be used
when outside conditions such as smoke,
odors, dust, or high humidity are present. This will cause
the LED to illuminate.
NOTE:
•The surface of the climate control panel, and the top
center of the instrument panel should be kept free of
debris due to the climate control sensor’s location.
Mud on the windshield may also cause poor operation
of this system.
•To provide you with maximum comfort in the auto-
matic mode, during cold start-ups the blower fan will
remain off until the engine warms up. However, the
fan will engage immediately if the defrost mode is
selected or if you manually select a blower speed.
•Under certain conditions (after the vehicle is turned
off) the climate control system may recalibrate and a
noise may be heard for 20 seconds. This is part of
normal operation.
•Most of the time, when in Automatic operation, you
can temporarily put the system into Recirculation
mode by pressing the “Recirculation” button. How-
ever, under certain conditions in automatic the system
is blowing air out of the defrost vents. When these
conditions are present, and the “Recirculation” button
is pressed, the indicator will flash and remain off. This
tells you that you are unable to go into Recirculation
mode at this time. If you would like to go to Recircu-
lation mode, you must first move your mode knob to
Panel, Panel/Floor, or Floor, then press the “Recircu-
lation” button. This feature will reduce the possibility
of window fogging.
Recirculation

additional engine cooling may be required. If this situa-
tion 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 NEUTRAL (N) and press the accelerator
slightly for fast idle operation to increase coolant flow
and fan speed.
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 directly 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 condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will ensure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
