Lighting 5-3
Automatic Headlamp
System
When it is dark enough outside, the
automatic headlamp system turns
on the headlamps at the normal
brightness, along with the taillamps,
sidemarker, parking lamps, and the
instrument panel lights. The radio
lights will also be dim.
To turn off the automatic headlamp
system, turn the exterior lamps
switch to the off position and then
release it.
The vehicle has a light sensor
located on the top of the instrument
panel in the defroster grille
which regulates when the
automatic headlamps turn on.
Do not cover the sensor, otherwise
the headlamps will come on
whenever the ignition is on.
The system may also turn on the
headlamps when driving through
a parking garage, heavy overcast
weather, or a tunnel. This is normal.
If the vehicle is started in a dark
garage, the automatic headlamp
system will come on immediately.
Once the vehicle leaves the garage,
it takes approximately one minute
for the automatic headlamp system
to change if it is bright enough
outside. During that delay, the
instrument panel cluster may not
be as bright as usual. Make sure
the instrument panel brightness
control is in the full bright position.
See Instrument Panel Illumination
Control on page 5‑6.
To idle the vehicle with the
automatic headlamp system off,
turn the control to the off position.
The headlamps will also stay
on after you exit the vehicle.
This feature can be programmed
using the Driver Information Center
(DIC). See Vehicle Personalization
on page 4‑51.
The regular headlamp system can
be turned on when needed.
