WARNING LIGHTS AND CHIMES
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
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.

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 toBulbsin theMaintenance and carechapter.
High beams
Illuminates when the high beam
headlamps are turned on.
Anti-theft system (if equipped)
Refer toSecuriLockypassive
anti-theft systemin theControls
and featureschapter.
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.
Check gage
Illuminates when the engine coolant
temperature is high, the engine oil
pressure is low or the fuel gauge is
at or near empty. The ignition must
be in the ON position for this lamp to illuminate. The lamp will also stay
illuminated after the ignition is turned to the ON position. Refer to
Engine coolant temperature gauge, Engine oil pressure gaugeor
Fuel gaugein this chapter for more information.

Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If your ªCheck Engine/Service Engine
Soonº light is on, refer to the description in theWarning Lights and
Chimessection of theInstrumentationchapter. Your vehicle may not
pass the I/M test with the ªCheck Engine/Service Engine Soonº light on.
If the vehicle's powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a ªnot ready for I/M testº
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
²First, at least 10 minutes of driving on an expressway or highway.
²Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
BULBS
Replacing exterior bulbs
Check the operation of the following lamps frequently:
²Headlamps
²Foglamps
²High-mount brakelamp
²Brakelamps
²Turn signals
²License plate lamp
²Tail lamps
²Back-up lamps
Do not remove lamp bulbs unless they can be replaced immediately with
new ones. If a bulb is removed for an extended period of time,
contaminants may enter the lamp housings and affect lamp performance.

from the bulb socket, and slide the
ring off the plastic base. Keep the
ring to retain the new bulb.
4. Remove the old bulb from the
lamp assembly by gently pulling it

To install the new bulb:
Handle a halogen headlamp bulb carefully and keep out of
children's reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil from your hand could cause the bulb to
break the next time the headlamps are operated.

If the bulb is accidentally touched, it should be cleaned with rubbing
alcohol before being used.
1. With the flat side of the new bulb's plastic base facing upward, insert
the glass end of the bulb into the lamp assembly. You may need to turn
the bulb left or right to align the grooves in the plastic base with the
tabs in the lamp assembly. When the grooves are aligned, push the bulb
into the lamp assembly until the plastic base contacts the rear of the
lamp assembly.
2. Install the bulb retaining ring over the plastic base until it contacts the
rear of the socket by rotating clockwise until you feel a ªstop.º
3. Install the electrical connector into the rear of the plastic base until it
snaps, locking it into position.
4. Turn the headlamps on and make sure they work properly. If the
headlamp was correctly aligned before you changed the bulb, you should
not need to align it again.
Replacing front parking lamp/turn signal bulbs
1. Make sure headlamp switch is in
OFF position, then lift hood and
open the hinged headlamp cover.
