BULBS
Replacing exterior bulbs
Check the operation of the following lamps frequently:
²Headlamps
²Foglamps
²High-mount brakelamp
²Brakelamps
²Turn signals
²License plate lamp

contaminants may enter the lamp housings and affect lamp performance.
Replacing headlamp bulbs
To remove the headlamp bulb:
1. Make sure headlamp switch is in
OFF position, then open the hood.
2. Remove two screws and cover (if
equipped).
3. At the back of the headlamp, pry
up the two retainer pins to release
the headlamp assembly from the
vehicle and pull headlamp forward.

5. Remove the bulb retaining ring by
rotating it counterclockwise (when
viewed from the rear) to free it
from the bulb socket, and slide the
ring off the plastic base. Keep the
ring to retain the new bulb.
6. Without turning, remove the old
bulb by gently pulling it straight
back out of the lamp assembly.
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.
1. With the flat side of the 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 plastic base until it snaps,
locking it into position.
4. Install the headlamp on vehicle, push rearward and secure with two
retainer pins.
5. Install the cover with two screws (if equipped).
6. 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.

ªEº for Europe to assure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.
