Headlamps On Reminder; Daytime Running Lamps (Drl) - GMC T-Series 2007 Owner's Manual

(Headlamps): Turn the band to this position
2
to turn on all the headlamps, together with
the previously listed lamps and lights.
A circuit breaker protects the headlamps. If you
have an electrical overload, the headlamps
will flicker on and off. Have the headlamp wiring
checked right away if this ever happens.

Headlamps on Reminder

If your vehicle has this feature, an alarm will sound
when the headlamps and/or parking lamps are
turned on and the ignition is in LOCK or ACC.

Daytime Running Lamps (DRL)

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. Fully functional daytime running lamps
are required on all vehicles first sold in Canada.
The DRL system will make the headlamps come
on at reduced brightness when the following
conditions are met:
•
The ignition is on.
•
The headlamp band is in the OFF position.
•
The parking brake is released.
When the DRL are on, only your low-beam
headlamps will be on. The exterior lamps and
instrument panel will not be lit.
The other lamps that come on with your
headlamps, will also come on.
When the headlamp band is turned to OFF,
the regular lamps will go off, and the low-beam
headlamps will change to the reduced brightness
of DRL.
When it begins to get
dark, the DRL indicator
light is a reminder to
turn your headlamp
switch on.
