Replacing headlamp bulbs
Make sure the headlamp switch is in the OFF position.
To remove the high or low beam headlamp bulb:
1. Lift the hood and release the wire
clip on the rear of the headlamp
assembly and remove the cover.
2. Disconnect the electrical
connector by turning the bulb
holder counterclockwise.
3. Pull the bulb holder straight out
to remove the bulb.
To install the new bulb:
Handle a halogen headlamp bulb carefully and keep out of
children's reach. Grasp the bulb by only 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.
1. Install the new bulb in the lamp assembly by pushing it straight in and
turning to lock it in position. You may need to turn the bulb slightly to
align the grooves in the plastic base with the tabs in the lamp assembly.
