When the DRL are on, only the parking lamps or
reduced intensity low beam headlamps will be on.
The taillamps, sidemarkers, and other lamps will not be
on. The instrument panel will not be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.
The regular headlamp system should be turned on
when needed.
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 more dim 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 may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. 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 3-15.
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.
