Exterior Lamp Controls

The exterior lamp control is on the
instrument panel to the left of the steering
wheel.
There are four positions:
: Briefly turn the control to this position
to turn the automatic headlamps off or
back on.
AUTO : Automatically turns the exterior
lamps on and off, depending on outside
lighting.
: Turns on the parking lamps, taillamps,
instrument panel lights, and license plate
lamps.
: Turns on the headlamps, parking
lamps, taillamps, instrument panel lights,
and license plate lamps.
If the headlamps are turned on while the
vehicle is on, the headlamps turn off
automatically 10 minutes after the ignition
is turned off. If the headlamps are turned on
while the vehicle is off, the headlamps will
continue to stay on. To prevent the battery
from being drained, turn the control to the
position.
A warning chime sounds if the driver door is
opened while the ignition switch is off and
the headlamps are on.
To change the headlamps from low beam to
high beam, pull the turn signal lever all the
way toward you. Then release it.
