time after the ignition switch is
turned to OFF.
The autolamps are turned on at
night or when the front wipers are
turned on.
•To turn autolamps on, rotate the control counterclockwise. The
preselected time lapse is adjustable up to approximately three
minutes. See the programming procedure following.
•To turn autolamps off, rotate the control clockwise to the off position
(O).
The amount of time the autolamps stay on can be programed by doing
the following:
1. Turn the ignition to OFF.
2. Turn the headlamp switch to the Autolamp position.
3. Turn the headlamp switch to OFF.
4. Turn the ignition to RUN and then back to OFF.

Daytime running lamps (DRL) (if equipped)
The daytime running light system turns the headlamps on, with a
reduced light output, when:
•the ignition is in RUN,
•the transmission is not in P (Park),
•the high beams are not in the flash to pass position and
•the headlamp system is not turned on by another feature such as
using the headlamp control or Autolamp.
Always remember to turn on your headlamps at dusk or during
inclement weather. The Daytime Running Light (DRL) System
does not activate the tail lamps and generally may not provide
adequate lighting during these conditions. Failure to activate your
headlamps under these conditions may result in a collision.
High beams
Push the lever toward the
instrument panel to activate. Pull
the lever towards you to deactivate.
Flash to pass
Pull toward you slightly to activate
and release to deactivate.

approximately 25 feet (7.6 meters) away.
•(1) 8 feet (2.4 meters)
•(2) Center height of lamp to
ground
•(3) 25 feet (7.6 meters)
•(4) Horizontal reference line

headlamp bulb center from the
ground and mark an 8 foot (2.4
meter) horizontal reference line on
the vertical wall or screen at this
height (a piece of masking tape works well).
