Halogen bulbs contain gas under pressure.
Handling the
bulb incorrectly could cause it
to shatter into flying glass fragments. Do
NOT leave the light switch ON. Always allow
the bulb to cool before removal. Handle the
bulb only by the base; avoid touching the
glass itself. Whenever handling a halogen
bulb, ALWAYS follow these precautions:
l Turn the headlight switch OFF and allow the
bulb to cool before changing it. Leave the switch OFF
until the change is complete.
l ALWAYS wear eye protection when changing a
halogen bulb.
l Handle the bulb only by its base. Avoid touch-
ing the glass.
l DO NOT drop or scratch the bulb. l Keep dirt and moisture away from the bulb.
* Place the used bulb in the new bulb’s carton
and dispose of it properly.
1. Open the vehicle’s hood and secure it in an up-
right position.
2. Disconnect the negative battery cable.
3. Remove the socket cover by pulling it straight
off, or turning it clockwise then pulling it off.
4. Carefully twist the bulb and socket counter-
clockwise, then pull the assembly from the headlight
housing.
5. Holding the base of the bulb, detach it from the
connector harness.
To install:
6. Holding the base of the bulb, install it securely
in the connector.
7. Install the connector and bulb assembly in the

About once a year, when the headllgftts are
replaced or any time front end work is per-
formed on your vehicle, the headlight should
be accurately aimed by a reputable repair
shop uslng the proper equipment. Headlights
not properly aimed can make it virtually im-
possible to see ar Id may blind other drivers
ibly causing an accident.
Note that the’following procedure is a tempo-
rary fix, until you can take your vehicle to a
repair shop for a proper adjustment.
Headlight adjustment may be temporarily made
using a wall, as described below, or on the rear of
another vehicle. When adjusted, the lights should not For most of the vehicles covered by this manual,
horizontal and vertical aiming of eachsealed beam
unit is provided by two adjusting screws which move
the retaining ring and adjusting plate against the ten-
sion of a coil spring. There is no adjustment for fo-
cus; this is done during headlight manufacturing.
*Because the composite headlight assem-
bly is bolted into position, no adjustment
should be necessary or possible. Some ap-
plications, however, may be bolted to an ad-
juster plate or may be retained by adjusting
screws. If so, follow this procedure when ad-
@sting the lights, BUT always have the ad-
justment checked by a reputable shop.
Before removing the headlight bulb or disturbing
the headlamp in any way, note the current settings in
order to ease headlight adjustment upon reassembly.
If the high or low beam setting of the old lamp still
works, this can be done using the wall of a garage or
a building:
1. Park the vehicle on a level surface, with the
fuel tank about r/a full and with the vehicle empty of
all extra cargo (unless normally carried). The vehicle
should be facing a wall which is no less than 6 feet
(1.8m) high and 12 feet (3.7m) wide. The front of the
vehicle should be about 25 feet from the wall.
2. If aiming is to be performed outdoors, it is ad-
visable to wait until dusk in order to properly see the
% and/or turning it counterclockwise. Make sure the
cover is installed securely or the lens will be out of
focus, or water may get into the light unit.
9. Disconnect the negative battery cable and
check the headlight operation.
