Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, the automatic headlamp system
turns on the headlamps along with other lamps such as
the taillamps, sidemarker, parking lamps, roof marker
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. For vehicles first sold in Canada, the
transmission must be in the P (Park) position, before
the automatic headlamp system can be turned off.
The vehicle has a light sensor located on the top of the
instrument panel. Do not cover this sensor or the
system will come on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, a tunnel, or while
driving in heavy overcast weather. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the automatic headlamp systems so that
driving under bridges or bright overhead street lights
does not affect the system. The DRL and automatic
headlamp system is only affected when the light sensor
sees a change in lighting lasting longer than the delay.
If the vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it takes approximately
one minute for the automatic headlamp system to
change to DRL if it is light 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
