When it begins to get dark, the headlamps will
automatically switch from DRL to the regular
headlamps. See ªAutomatic Light Controlº earlier in
this section.
When you turn the headlamp switch to off, the regular
lamps will go off and your headlamps will change to the
reduced brightness of DRL provided it is not dark
outside. DRL also comes on if only the parking lamps
are being used.
To idle your vehicle with the DRL off, set the parking
brake. The DRL 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.
Automatic Light Control (ALC)
Your vehicle is equipped with an automatic light sensor
on top of the instrument panel, so be sure it is not
covered which will cause the nighttime lights to be
on continuously.When it is dark enough outside, your ALC will turn on
your low
-beam headlamps at the normal brightness
along with other lamps such as the taillamps,
sidemarker, park lamps and instrument panel lights.
There is a short delay in the transition between daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the ALC systems. If the light sensor senses a
reduction in lighting that lasts longer than 20 seconds, it
will activate the nighttime lamps. If you are driving
through a parking garage, heavy overcast weather or a
tunnel, the ALC will turn on your low
-beam headlamps
at a normal brightness along with the taillamps,
sidemarker, park lamps and the instrument panel lights.
The radio lights will be dimmer.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Lamps On Reminder
If you turn the ignition off, remove the key, open the
door and leave the lamps on, a tone will remind you to
turn off your lamps.
