headlamp HUMMER H2 2007 User Guide

2(Headlamps):Turn the control to this position
to turn on the headlamps, together with the
previously listed lamps and lights.
When the vehicle is turned off and the headlamps
are in AUTO, the headlamps may automatically
remain on for a set time. You can change
this delay time using the DIC. SeeDriver
Information Center (DIC) on page 222.
You can switch your headlamps from low to
high-beam by pushing the turn signal/multifunction
lever toward the instrument panel.
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”
underDIC Vehicle Customization on page 234.
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 rst 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 your 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.
188

To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release.
For vehicles rst sold in Canada, the transaxle
must be in the PARK (P) position, before the
DRL lamps can be turned off.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, your automatic headlamp
system will turn on your headlamps at the normal
brightness along with other lamps such as the
taillamps, sidemarker, parking lamps, roof marker
lamps, and the instrument panel lights. The radio
lights will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then
release. For vehicles rst sold in Canada, the
transaxle must be in the PARK (P) position, before
the automatic headlamp system can be turned off.
Your vehicle has a light sensor located on the top
of the instrument panel. Be sure it is not
covered, or the system will be on whenever the
ignition is on.The system may also turn on your headlamps
when driving through a parking garage, heavy
overcast weather, or a tunnel. This is normal.
There is a delay in the transition between the
daytime and nighttime operation of the Daytime
Running Lamps (DRL) and the automatic headlamp
systems so that driving under bridges or bright
overhead street lights does not affect the system.
The DRL and automatic headlamp system will only
be affected when the light sensor sees a change in
lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take approximately one minute for the automatic
headlamp system to change to DRL if it is
light outside. During that delay, your instrument
panel cluster may not be as bright as usual. Make
sure your instrument panel brightness control is
in the full bright position. SeeInstrument
Panel Brightness on page 191.

the thumbwheel, located next to the exterior
lamp control, all the way up. In this position, the
dome lamps will remain on whether a door is
opened or closed.

Automatic Operation
AUTO (Automatic):When automatic operation is
active the system will control the inside
temperature, the air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will
change to show the current driver’s set
temperature, delivery mode and fan speed.
Press the AUTO button again within
ve seconds to display the passenger’s set
temperature.
If the driver and passenger’s temperature
settings are not the same, the opposite side
temperature setting will be displayed for
an additional ve seconds. To make the
passenger’s temperature the same as
the driver’s press and hold the AUTO button
for about four seconds.
When auto is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will
run when the outside temperature is over about
40°F (4°C). The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet mayautomatically switch to recirculate inside air to
help quickly cool down your vehicle. The light
on the button will illuminate in recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F
(23°C) temperature setting and allow about
20 minutes for the system to regulate. Turn the
driver’s or passenger’s side temperature knob
to adjust the temperature setting as necessary.
If you choose the temperature setting of 60°F
(15°C) the system will remain at the maximum
cooling setting. If you choose the temperature
setting of 90°F (32°C) the system will remain at
the maximum heat setting. Choosing either
maximum setting will not cause the vehicle to
heat or cool any faster.
Be careful not to cover the sensor located on
the top of the instrument panel near the
windshield. This sensor regulates air
temperature based on sun load, and also
turns on your headlamps.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until
warm air is available. The length of delay
depends on the engine coolant temperature.
Pressing the fan switch will override this delay
and change the fan to a selected speed.
