Headlight Aiming
The headlights were properly aimed
when your vehicle was new. If you
regularly carry heavy items in the
trunk, readjustment may be required.
Adjustment should be done by your
dealer or other qualified mechanic.
Replacing a Headlight Bulb
The low beam headlight bulbs are a
type of high voltage discharge tube.
High voltage can remain in the
circuit even with the light switch off
and the key removed. Because of
this, you should not attempt to
examine or change a low beam
headlight bulb yourself. If a low
beam headlight bulb fails, take the
vehicle to your dealer to have it
replaced.
Halogen bulbs are used for the high
beam headlight bulbs. When
replacing a high beam headlight bulb,
handle it by its base, and protect the
glass from contact with your skin or
hard objects. If you touch the glass,
clean it with denatured alcohol and a
clean cloth.
