Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system will turn on after the transmission has
been shifted from P (Park) to D (Drive). The headlamps,
taillamps, sidemarker, parking lamps, roof marker
lamps, and the instrument panel lights turn on at normal
brightness. The radio lights will become dimmer when
the headlights are off compared to when the headlights
are on.
The vehicle has a light sensor located on the top of
the instrument panel. Do not cover the sensor, or the
system will be on whenever the ignition is on.
The system can turn on the headlamps when driving in
a parking garage, through a tunnel or when there is
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 system so that
driving under bridges or bright overhead street lights
does not affect the system. The DRL and automatic
headlamp system will only be affected when the light
sensor detects a change in lighting lasting longer than
the delay.
If the vehicle is started in a dark garage, the automatic
headlamp system will come on immediately. Once the
vehicle leaves the garage, it will take about 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 Instrument Panel Brightness
on

Fog Lamps
The fog lamp button is located near the exterior lamps
control.
# : For vehicles with fog lamps, press to turn the fog
lamps on or off. An indicator light will turn on in the
button when the fog lamps are on.
The parking lamps or lowbeam headlamps must be on
for the fog lamps to work. The fog lamps will go off
whenever the high-beam headlamps come on. When
the high beams go off, the fog lamps come on again.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
