BULBS
Replacing exterior bulbs
Check the operation of the following lamps frequently:
•Headlamps
•High-mount brakelamp
•Brakelamps
•Turn signals
•License plate lamp
•Tail lamps
•Back-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 (aerodynamic)

2. Open the hood.
3. Disconnect the electrical connector from the bulb by pulling rearward.
4. Remove bulb retainer ring by
turning it counterclockwise, then
slide the ring off the plastic base.
5. Without turning, carefully pull
bulb out of headlamp assembly.
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.
