The DRL system will make your high-beam headlamps come on at a reduced brightness when: The engine is running, 0 Automatic Light Control (ALC) Your vehicle is equipped with an automatic light sensor on top of the instrument panel under the defroster grill, 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 willturn 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 20-second delay in the transition between daytime and nighttime operation of the 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 aredriving through a parking garage, heavy overcast weather, a tunnel or fueling your vehicle in a low light area, the ALC will turn onyour low-beam headlamps at a normal brightness along with the taillamps, sidemarker, park lamps and the instrument panel lights.

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 engine is running,
0
The headlamp switch is in the
OFF
position,
The light sensor detects daytime light,
0
The parking brake is released and
The shift lever is
not
in PARK (P) on
an
automatic transaxle.
When the DRL system is on, the taillamps, sidemarker,
park lamps
and
instrument panel lights will
not be
illuminated.
The
DRL
and
the ALC systems will remain off any
time
your automatic transaxle vehicle is in PARK (P)
andthe
parking brake is engaged.
The DRL
and the ALC systems will remain
off
any time
your manual transaxle vehicle is in
NEUTRAL (N) and
the parking brake is engaged.
Automatic
Light
Control
(ALC)
Your vehicle is equipped with
an automatic light sensor
on top of the instrument panel under the defroster grill,
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 20-second delay in the transition between
daytime and nighttime operation
of
the
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
aredriving through a
parking garage, heavy overcast weather, a tunnel or
fueling your vehicle in a low light area, 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.
