GMC savana 2002 사용자 설명서

A tone will sound when your headlamps are turned on
and your ignition is in OFF, LOCK or ACCESSORY. 
If you need to use your headlamps when the ignition
switch is in OFF, LOCK or ACCESSORY, the tone 
can be turned off by moving the instrument panel
brightness thumbwheel next to the exterior lamp control
all the way down.

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 your headlamps come on 
at a reduced brightness when the following conditions
are met:
D The ignition is on,
D The exterior lamp control is off, and
D 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 the headlamps on. The other lamps that
come on with your headlamps will also come on.

When you turn off the headlamps, the regular lamps will
go off, and your headlamps will change to the reduced
brightness of DRL.

To idle your vehicle with the engine on and the DRL off,
set the parking brake. The DRL will stay off until you
release the parking brake.

As with any vehicle, you should turn on the regular
headlamp system when you need it.
