Chevrolet Blazer 2001 User Manual

To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system 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.

You may be able to turn off your automatic headlamp
system. See “Daytime Running Lamps (DRL)” later 
in this section for more information

A reminder chime will sound when your headlamps or
parking lamps are manually turned on, the driver’s 
door is opened and your ignition is in OFF, LOCK or
ACCESSORY. To turn the chime off, turn the knob all
the way to the left or turn the instrument panel dimmer
down to the fully dimmed position. In the automatic
mode, the headlamps turn off once the ignition key is 
in OFF.

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 lights are required 
on all vehicles first sold in Canada.

The DRL system will make your headlamps come on at
reduced brightness when the following conditions are met:
D The ignition is on,
D the headlamp switch is in automatic headlamp mode,
D the sensor detects daytime light,
D an automatic transmission is not in PARK (P), 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.
The instrument panel won’t be lit up either.

When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.
