GMC 2004 Savana - Manual (Page 137)

5 (Headlamps): Turn the control to this position to
turn on the headlamps together with the parking
lamps and turn off the daytime running lamps.
You can switch your headlamps from high to
low-beam by pulling the turn signal/high-beam lever
toward you.
A circuit breaker protects your headlamps. If you have
an electrical overload, your headlamps will flicker on and
off. Have your headlamp wiring checked right away if
this happens.
Lamps On Reminder
A reminder chime will sound when your control is turned
to the headlamps or parking lamps position, your key
is out of the ignition, and your driver’s door is open. To
disable the chime, turn the control to the Daytime
Running Lamp (DRL) position and then back to the
parking lamps or headlamps position.
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. Fully functional
daytime running lamps are required on all vehicles
first sold in Canada.
The DRL system will come on when the following
conditions are met:
• the ignition is on,
• the exterior lamps control in DRL mode and not in
the defeat position.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. The instrument panel will be lit.
When you turn the headlamp switch off, the headlamps
will go off, and your DRL lamps will illuminate.
Turn the exterior lamp control to the defeat position or
shift into PARK (P). The DRLs will stay off until the
control is toggled again or the vehicle is shifted out of
PARK (P).
This procedure applies only to vehicles first sold in the
United States.
