ensuring that your vehicle
continues to meet government
emission standards. The OBD II
system also assists the service
technician in properly servicing
your vehicle.

If the vehicle's powertrain system
or its battery has just been
serviced, the OBD-II system is
reset to a ªnot ready for I/M testº
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
Replacing exterior bulbs
Check the operation of the
following lamps frequently:
²Headlamps
²Tail lamps
²Brakelamps
²High-mount brakelamp
²Turn signals
Maintenance and care
166

²Backup lamps
²License plate lamp
Do not remove lamp bulbs unless
they will be replaced immediately.
If a bulb is removed for an
extended period of time,
contaminants may enter the lamp
housings and affect 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.
To remove the headlamp bulb:
1. Make sure headlamp switch is in
OFF position.
2. Open the hood.
3. Twist the plastic knobs to
release the plastic sight shield
covering the back of the
headlamps. Lift the shield and pull
towards the windshield.
Maintenance and care
167

4. Remove headlamp by taking the
pins out. Pull headlamp forward to
access headlamp connector.
5. Disconnect the electrical
connector from the bulb by pulling
the connector rearward.
6. Remove the bulb retaining ring
by rotating it counterclockwise
(when viewed from the rear) 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.
7. 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. 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.
Maintenance and care
168

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 ªstop.º
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.
5. Carefully insert the headlamp
assembly into the vehicle making
sure the alignment pins are
inserted into the proper holes and
into the guides.
AIMING THE HEADLAMPS
Your vehicle is equipped with a
Vehicle Headlamp Aim Device
(VHAD) on each headlamp body.
Each headlamp may be properly
aimed in the horizontal direction
(left/right) and the vertical
position (up/down).
A non-zero bubble reading does
not necessarily indicate out-of-aim
headlamps. If your vehicle is not
positioned on a level surface, the
slope will be included in the level
indicator. Therefore, vertical
headlamp adjustment should be
performed only when beam
direction appears to be incorrect
or a level surface can not be
verified.
Maintenance and care
169

2. With the hood open, locate the
bubble level vertical aim indicator.
It is visible when viewed from the
above rear of the headlamp.
3.Usea4mmwrench to turn the
vertical adjusting screw until the
reference mark on the reflector
extension aligns with the ª0º
reference mark on the vertical
indicator when viewed directly
from above.
4. Close the hood.
