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.

the Vehicle Emission Control Information Decal located on or near the
engine. This decal identifies engine displacement and gives some tune up
specifications.
Please consult your ``Warranty Guide'' for complete emission warranty
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 diagnostic (OBD-II) system. If your ``check engine/service
engine soon'' light is on, reference the applicable light description in the
Warning Lights and Chimessection of your owners guide. Your vehicle
may not pass the I/M test with the ``check engine/service engine soon''
light on.
If the vehicle's powertrain system or its battery has just been serviced,
the OBD-II system is reset to a ``not ready for I/M test'' condition. To
ready the OBD-II 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.
EXTERIOR BULBS

²license plate lamp
²tail lamps
Maintenance and care

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.
Replacing headlamp bulbs
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.
To remove the headlamp bulb:
1. Make sure headlamp switch is in OFF position, then open the hood. If
you are replacing the driver side headlamp, unclip the electronic module
on the right side of the battery and move it out of the way.
2. Locate the headlamp bulb through the hole in the upper radiator
support assembly.
3. Disconnect the electrical
connector from the bulb by pulling
the connector rearward.
4. Remove the bulb retaining ring by
rotating it counterclockwise (when
viewed from the rear) about an
eighth of a turn to free it from the
bulb socket, and by sliding the ring
off the plastic base. Keep the ring
because it will be used again to
retain the new bulb.

5. Remove the old bulb from its socket by gently pulling it straight back
out of the socket. Do not turn the bulb while removing it.
To install the new bulb:
1. With the flat side of the bulb's
plastic base facing upward, insert
the glass end of the bulb into the
socket. You may need to turn the
bulb left or right to line up the
grooves in the plastic base with the
tabs in the socket. When the
grooves are aligned, push the bulb
into the socket until the plastic base
contacts the rear of the socket.
2. Slip the bulb retaining ring over the plastic base until it contacts the
rear of the socket by rotating it clockwise until you feel a ``stop''.
3. Push 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.
