Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
The DRL system will make your high
-beam headlamps
come on at a reduced brightness when:
The ignition is on,
the headlamp switch is in OFF or you have turned on
your parking lamps,
the light sensor detects daytime light,
the parking brake is released and
the shift lever is not in PARK (P) on vehicles with an
automatic transaxle.
When the DRL system is on, the taillamps, sidemarker
lamps, park lamps and instrument panel lights will not
be illuminated.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Automatic Light Control (ALC)
When it is dark enough outside, your Automatic Light
Control (ALC) will turn on your headlamps along with
other lamps such as the taillamps, sidemarker lamps,
park 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 defroster grill, so be
sure it is not covered. This will cause the ALC system to
be on whenever the ignition is on.
The ALC system may also come on when driving
through a parking garage, heavy overcast weather or a
tunnel. This is normal.
