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 page 4‑13. 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 low‐beam 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. 4-12

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

(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
