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 headlamps come on at
a reduced brightness when:
0
the ignition is on,
0
the headlamp switch is off and
the parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be on.
Your instrument panel won't be lit up either.
When it begins
to
get dark, your DRL indicator light is a
reminder to turn your headlamp switch on. The other lamps
that come on
with
your headlanips will also come on.
When you turn off the headlamp switch, the regular
lamps will go off, and your headlamps will change to
the reduced brightness of DRL.
