WARNING LIGHTS AND CHIMES
Standard instrument cluster
Optional instrument cluster
Low fuel (if equipped)
Illuminates as an early reminder of a
low fuel condition indicated on the
fuel gauge (refer toFuel gaugein
this chapter for more information).
When refueling, after the light
comes on, the amount of fuel that is added will be less than the
advertised capacity since there is fuel still in the tank. The ignition must
be in the ON position for this lamp to illuminate. The lamp will also
illuminate for several seconds after the ignition is turned to the ON
position regardless of the fuel level to ensure your bulb is working.

Check engine
Your vehicle is equipped with a
computer that monitors the engine's
emission control system. This
system is commonly known as the
On Board Diagnostics System (OBD
II). This OBD II system protects the environment by ensuring that your
vehicle continues to meet government emission standards. The OBD II
system also assists the service technician in properly servicing your
vehicle.
TheCheck Engineindicator light illuminates when the ignition is first
turned to the ON position to check the bulb. If it comes on after the
engine is started, one of the engine's emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.
What you should do if the check engine light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourCheck Enginelight to
illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the gas cap. After three driving cycles
without these or any other temporary malfunctions present, theCheck
Enginelight should turn off. (A driving cycle consists of a cold engine
startup followed by mixed city/highway driving.) No additional vehicle
service is required.
If theCheck Enginelight remains on, have your vehicle serviced at the
first available opportunity.

Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Check fuel cap (if equipped)
Momentarily illuminates when the
ignition is turned to the ON position
to ensure your bulb is working.
When this light turns on, check the
fuel filler cap. Continuing to operate
the vehicle with the check fuel cap light on, can activate theService
Engine Soon/Check Enginewarning light. When the fuel filler cap is
properly re-installed, the light(s) will turn off after a period of normal
driving. This period will vary depending on driving conditions.
It may take a long period of time for the system to detect an
improperly installed fuel filler cap.
For more information, refer toFuel filler capin theMaintenance and
carechapter.
Air bag readiness
Momentarily illuminates when the
ignition is turned ON. If the light
fails to illuminate, continues to flash
or remains on, have the system
serviced immediately.

Charging system
Illuminates when the ignition is
turned to the ON position and the
engine is off. The light also
illuminates when the battery is not
charging properly, requiring
electrical system service.
Engine oil pressure (if equipped)
Illuminates when the oil pressure
falls below the normal range. Stop
the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level and
add oil if needed. Refer toEngine oilin theMaintenance and care
chapter.
This lamp also illuminates when the ignition is turned to ON and the
engine is off.
Air suspension (if equipped)
²Standard instrument cluster
²Optional instrument cluster
Momentarily illuminates when the
ignition is turned to the ON
position. Also illuminates when the
air suspension requires repair, the
air suspension switch is OFF or the
load limit is exceeded. For
information on the air suspension system, refer to theDrivingchapter.

Illuminates when the Transmission
Control Switch (TCS), refer to
Overdrive controlin theControls
and Featureschapter, has been
pushed turning the transmission
overdrive function OFF. When the
light is on, the transmission does not operate in the overdrive mode,
refer to theDrivingchapter for transmission function and operation.
The light may also flash steadily if a transmission malfunction is
detected. If the light does not come on when the Transmission Control
Switch is depressed or if the light flashes steadily, have your vehicle
serviced as soon as possible, damage to the transmission could occur.
Traction ControlYactive (if equipped)
Flashes when the Traction Controly
system begins applying and
releasing the brakes and adjusting
the engine characteristics to limit a
wheelspin condition. It will be lit for a minimum of four seconds or for
the duration of the Traction Controlyevent.
If the Traction Controlyindicator comes on or stays lit, either:
²the Traction Controlysystem needs service, or
²the customer has disabled the system using the traction control switch
in the instrument panel.
For more information, refer to theDrivingchapter.

GAUGES
Standard instrument cluster gauges
Optional instrument cluster gauges
Fuel gauge
Displays approximately how much fuel is in the fuel tank (when the key
is in the ON position). The fuel gauge may vary slightly when the vehicle
is in motion. The ignition should be in the OFF position while the vehicle
is being refueled. When the gauge first indicates empty, there is a small
amount of reserve fuel in the tank. When refueling the vehicle from
empty indication, the amount of fuel that can be added will be less than
the advertised capacity due to the reserve fuel.

²Optional instrument cluster
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate. If the gauge enters the red section, the engine
coolant andCheck Engine/Service Engine Soonindicators illuminate,
refer toWhat you should know about fail-safe coolingin the
Maintenance and carechapter.
Battery voltage gauge (if equipped)
This shows the battery voltage when
the ignition is in the ON position. If
the pointer moves and stays outside
the normal operating range (as
indicated), have the vehicle's
electrical system checked as soon as
possible.
