DESCRIPTION AND OPERATION
HEADLAMPS AND PARKING LAMPS
The headlamps are controlled by the multifunction lever
located on the left side of the steering column. They will
come on with the ignition switch in any position. Turning
the headlamp switch to the first position turns on the
parking lamps, the license plate lamps and the instru-
ment panel illumination. Turning the switch to the sec-
ond position turns on all of the previous lamps and the
headlamps. Turning the switch to the off position turns
off all the lamps.
The parking lamps can be turned on by turning the light-
ing switch to the first position. The parking lamps can be
turned off by turning the switch to the OFF position.
Headlamp high beam and low beam are also controlled
by this lever. When the headlamps are on, pushing the
lever away from the driver until the switch clicks
changes the lamp from low beam to high beam. An indi-
cator lamp on the instrument cluster assembly will come
on when the high beam headlamps are on. To return the
headlamps to low beam, pull the lever toward the driver.
The headlamps must be aimed for proper illumination of
the road. Headlamp aim should be checked whenever a
new headlamp assembly is installed or service repairs to
the front end area may have disturbed the headlamp as-
sembly or its mountings.
FRONT TURN SIGNAL LAMPS
When the turn signals are activated, the side turn signal
lamps flash to signal a turn. The turn signal works only
when the ignition switch is on.
The turn signals are controlled by the light switch on the
left side of the steering column. Moving the lever all the
way up or down (past the detent) will turn on the turn sig-
nals. When the turn is completed, the lever will return to
horizontal and the turn signals will stop flashing.
For changing lanes or shallow turns where the steering
wheel does not turn far enough to cancel the signal,
move the signal only to the first detent and hold it there.
When the lever is released, it will return to horizontal and
the turn signal will cancel.
REAR FOG LAMP
The rear fog lamp is incorporated in the drive side tail-
lamp assembly and are controlled by the rear fog lamp
switch on the instrument panel. The rear fog lamp can
be turned on only when headlamps are on.
TAILLAMPS
The taillamps, stoplamps, backup lamp(s), rear fog lamp
(if equipped with) and turn signal lamps are one assem-
bly.
Turning on either the headlamps or the parking lamps
will also turn on the taillamps. When the brake pedal is
pushed, the taillamps will glow brighter to serve as sto-
plamps.
The center high-mounted stoplamp is located in the rear
window and will come on when the brake pedal is
pressed.
LICENSE PLATE LAMPS
The license plate lamps will come on when the head-
lamps or the parking lamps are on. The license plate
lamps are mounted on the rear bumper, above the li-
cense plate.
INTERIOR COURTESY LAMP
The courtesy lamp is located on the headliner just be-
fore the front seats. The lamp switch has three posi-
tions. If the switch is in the center position, the lamp will
go on whenever a door is opened and go off when it is
closed. In the ON position, the lamp will stay on until it is
turned off. In the OFF position, the lamp will not come
on, even when a door is opened.
BACKUP LAMP(S)
The backup lamps are located in the rear combination
lamps. They will come on when the transaxle is shifted
into REVERSE. On a vehicle with a manual transaxle,
they are activated by a reverse switch which is part of
the transaxle.
DAYTIME RUNNING LAMPS (DRL)
(W/Europe Only)
The daytime running lamps (DRL) work in conjunction
with the exterior lamps system. When the ignition switch
is turned to the ”II” position with the light switch off, park-
ing, tail, license plate and instrument panel lights illumi-
nate. And, when the engine is started, the headlamps
(low beam) also come on.
They remain on until the ignition switch is turned off or
the light switch is turned on. They revert to normal op-
eration when the light switch is on.
The daytime running lamps (DRL) is optional.
