Hummer 2008 H2 - Manual (Page 167)

Headlamps on Reminder
If a door is open, a reminder chime will sound when
your headlamps or parking lamps are manually turned
on and your 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 or may remain on until the headlamp
delay ends (if enabled in the DIC). See “Exit Lighting”
under DIC Vehicle Customization (With DIC Buttons)
on page 3-63.
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 come on when the following
conditions are met:
• The ignition is on.
• The exterior lamps control is in AUTO.
• The transmission is not in PARK (P).
• The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, and other lamps will not
be on. The instrument panel will not be lit up either.
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 PARK (P) position, before the
DRL lamps can be turned off.
