WARNING LIGHTS AND CHIMES
Standard instrument cluster
Optional instrument cluster
Low fuel
Illuminates as an early reminder of a
low fuel condition indicated on the
fuel gauge. The light comes on when
there is approximately 1/16th of a
tank indicated on the fuel gauge
(refer toFuel Gaugein this chapter for more information). 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.

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 good quality fuel 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.

Anti-lock brake system (ABS) (If equipped)
Momentarily illuminates when the
ignition is turned on and the engine
is off. If the light does not illuminate
momentarily at start up, remains on
or continues to flash, the ABS needs
to be serviced. With the ABS light on, the anti-lock brake system is
disabled and normal braking is still effective unless the brake warning
light also remains illuminated with parking brake released.
Turn signal
Illuminates when the left or right turn
signal or the hazard lights are turned
on. If one or both of the indicators
stay on continuously or flash faster,
check for a burned-out turn signal
bulb. Refer toExterior bulbsin theMaintenance and carechapter.
High beams
Illuminates when the high beam
headlamps are turned on.
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 Carechapter.

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 care chapter.
Battery voltage gauge (if equipped)
This gauge 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.
Engine oil pressure gauge (if equipped)
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle remains
in the normal range (the area
between the ªHº and ªLº).
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.

dealership or by a qualified technician.
ELECTRONIC MESSAGE CENTER
The electronic message center only
works when the ignition is in the
ON position.
The message center allows you to:
²see problems such as door ajar,
air suspension, trunk ajar, washer
fluid low
²see how many kilometers/miles
you can drive before running out
of fuel
²see when overdrive has been deactivated
²monitor the average fuel economy
²check the distance traveled during a trip on either Trip A or Trip B
²monitor the average speed

Trunk ajar
If the trunk is not completely
closed, this light comes on when
you turn the ignition to ON. With
the ignition ON, this light will flash
five times and sound a tone for one
second, then remain on (if the trunk
is open).
INDICATOR LAMP MODULE
The indicator lamp module contains the following lamps:
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.
For more information, refer to theDrivingchapter.
Anti-lock brake system (ABS) (If equipped)
Momentarily illuminates when the
ignition is turned on and the engine
is off. If the light does not illuminate
momentarily at start up, remains on
or continues to flash, the ABS needs
to be serviced. With the ABS light on, the anti-lock brake system is
disabled and normal braking is still effective unless the brake warning
light also remains illuminated with parking brake released.CHECK
