Autolight system
The autolight system allows the headlights
to turn on and off automatically. The auto-
light system can:
• Turn on the headlights, front parking, tail,license plate and instrument panel lights
automatically when it is dark.
• Turn off all the lights when it is light.
• Keep all the lights on for a period of time af ter you place the ignition switch in the
OFF position and all doors are closed.
NOTE:
Autolight activation sensitivity and
the time delay for autolight shutoff
can be adjusted. For additional infor-
mation, refer to “Vehicle information
display ” in this section.
To turn on the autolight system:
1. Turn the headlight switch to the AUTO position
O1.
2. Turn the ignition switch to ON.
3. The autolight system automatically turns the headlights on and off.
Initially, if the ignition switch is placed in the
OFF position and a door is opened and lef t
open, the headlights remain on for a period
of time. If another door is opened while the
headlights are on, then the timer is reset.
To turn the autolight system off, turn the
switch to the OFF,
,orposition. Be sure you do not put anything on top
of the autolight sensor located in the top
side

is covered, the autolight sensor reacts as
if it is dark out and the headlights will
illuminate. If this occurs while parked
with the engine off and the ignition
switch placed in the ON position, your
vehicle's battery could become dis-
charged.
