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.

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.
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.
Safety belt
Momentarily illuminates when the
ignition is turned to the ON position
to remind you to fasten your safety
belts. For more information, refer to
theSeating and safety restraints
chapter.
Brake system warning (if equipped)
Momentarily illuminates when the
ignition is turned to the ON
position, the engine is off and the
parking brake is engaged. If brake
warning lamp does not illuminate at
this time, seek service immediately. Illumination after releasing the
parking brake indicates low brake fluid level and the brake system should
be inspected immediately.

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.

This lamp also illuminates when the ignition is turned to ON and the
engine is off.
Engine coolant temperature
Illuminates when the engine coolant
temperature is high. Stop the
vehicle as soon as safely possible,
switch off the engine and let it cool.
Never remove the coolant
recovery cap while the
engine is running or hot.
Refer toEngine coolantin theMaintenance and carechapter. If light
stays on or continues to turn on after the vehicle warms up, have your
vehicle serviced.
This light also illuminates briefly when the ignition key is turned to ON.
Air suspension (if equipped)
This light tells you if the air
suspension needs repair or if the air
suspension switch is OFF. For
information on the air suspension
system, refer to theDriving
chapter.

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.
