Headlamps On Reminder; Daytime Running Lamps (Drl) - Hummer H2 2009 Owner's Manual

When the headlamps are turned on while the vehicle is
on, the headlamps will turn off automatically 10 minutes
after the ignition is turned off. When the headlamps are
turned on while the vehicle is off, the headlamps will stay
on for 10 minutes before automatically turning off to
prevent the battery from being drained. Turn the
headlamp control to off and then back to the headlamp on
position to make the headlamps stay on for an additional
10 minutes.

Headlamps on Reminder

If a door is open, a reminder chime will sound when the
headlamps or parking lamps are manually turned on and
the key is out of the ignition. To turn off the chime, turn
the headlamp switch to off or AUTO and then back on,
or close and re-open the door. In the AUTO mode, the
headlamps turn off once the ignition is in LOCK/OFF or
may remain on until the headlamp delay ends (if enabled
in the DIC). See "Exit Lighting" under DIC Vehicle
Customization on page 3-64.

Daytime Running Lamps (DRL)

Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
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 is in AUTO.
•
The transmission is not in P (Park).
•
The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, instrument panel lights,
and other lamps will not be on.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release. For vehicles
first sold in Canada, the transmission must be in the
P (Park) position, before the DRL lamps can be
turned off.
