5. Remove the old headlamp bulb by
rotating it counterclockwise and pull
it out.
6. To install, reverse the removal
procedure. (Re-aiming the
headlamps may be necessary. For
additional information refer to the
headlamp aiming section in this
chapter.)
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.
Note:If the bulb is accidentally touched, it should be cleaned with
rubbing alcohol before being used.
Note:The headlamp bulb should not be removed from the headlamp
until just before a replacement bulb is installed. Removing the bulb for
an extended period of time may affect headlamp bulb performance.
Contaminants may enter the headlamp where they can settle on the lens
and reflector. Never turn the headlamps on with the bulb removed.
Replacing front parking/cornering/turn signal lamp bulbs
The park/turn/cornering lamp bulbs can be replaced without removing
the headlamp assembly.
1. Make sure headlamp switch is in OFF position, then open the hood.
2. Remove the three pin type retainers and the radiator shield.
3. Loosen the parking lamp attachments, on the back side of the lamp,
and pull the lamp assembly forward.

Note:The parking lamp/turn signal bulbs should not be removed from
the lamp until just before a replacement bulb is installed. Removing the
bulb for an extended period of time may affect headlamp bulb
performance. Contaminants may enter the headlamp where they can
settle on the lens and reflector. Never turn the lamps on with the bulb
removed.
Replacing tail lamp/brake/turn lamp bulbs
