Downloaded from www.Manualslib.com manuals search engine Rotate the knob to the right to the master lamps symbol
to turn on all the lamps listed as well as the headlamps.
Rotate the knob all the
way to the left to turn off your
lamps and put the system in auto headlamp mode.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor on the top
of the instrument panel under the radio speaker grill so
be sure it is not covered, which will cause the system to
be on whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather, a tunnel or fueling your vehicle in a low-light
area. 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 will
only be affected when the light sensor sees a
change in lighting lasting longer than the delay.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then
start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on and your ignition
is in
OFF, LOCK or ACCESSORY. To turn the chime
off, turn the knob all the way to the left or turn the
instrument panel dimmer down to the fully dimmed
position. In the automatic mode, the headlamps turn off
once the ignition key is in
OFF.
