light HUMMER H2 2007 Service Manual

An arrow on the
instrument panel
cluster will ash in the
direction of the turn
or lane change.
As you signal a turn or a lane change, if the
arrows ash more quickly than normal, a signal
bulb may be burned out and other drivers will not
see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when you
signal a turn, check for burned-out bulbs and a
blown fuse. SeeInstrument Panel Fuse Block on
page 504andUnderhood Fuse Block on page 507.Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a
mile (1.2 km), a chime will sound at each ash
of the turn signal and the message TURN SIGNAL
ON will also appear in the DIC. SeeDIC
Warnings and Messages on page 226. To turn the
chime and message off, move the turn signal
lever to the off position.
Headlamp High/Low-Beam Changer
53(Headlamp High/Low Beam Changer):
To change the headlamps from low to high beam,
push the lever toward the instrument panel. To
return to low-beam headlamps, pull the
multifunction lever toward you. Then release it.
When the high beams
are on, this indicator light
on the instrument panel
cluster will also be on.

Flash-to-Pass
This feature lets you use your high-beam
headlamps to signal a driver in front of you that
you want to pass. It works even if your headlamps
are in the automatic position.
To use it, pull the turn signal lever toward you,
then release it.
If your headlamps are in the automatic position or
on low beam, your high-beam headlamps will
turn on. They will stay on as long as you hold the
lever toward you. The high-beam indicator on
the instrument panel cluster will come on. Release
the lever to return to normal operation.
Windshield Wipers
You control the windshield wipers by turning the
band with the wiper symbol on it.
8(Mist):For a single wiping cycle, turn the
band to mist. Hold it there until the wipers
start. Then let go. The wipers will stop after
one wipe. If you want more wipes, hold the
band on mist longer.
6(Delay):You can set the wiper speed for a long
or short delay between wipes. This can be very
useful in light rain or snow. Turn the band to
choose the delay time. The closer to the top of the
lever, the shorter the delay.
6(Low Speed):For steady wiping at low
speed, turn the band away from you to the
rst solid band past the delay settings.
1(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band
to off.
Be sure to clear ice and snow from the wiper
blades before using them. If they are frozen to the
windshield, carefully loosen or thaw them. If
your blades do become worn or damaged, get
new blades or blade inserts.

Using Cruise Control on Hills
How well your cruise control will work on hills
depends upon your speed, load and the steepness
of the hills. When going up steep hills, you may
want to step on the accelerator pedal to maintain
your speed. When going downhill, you may
have to brake or shift to a lower gear to keep your
speed down. Of course, applying the brake
takes you out of cruise control. Many drivers nd
this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are four ways to turn off the cruise control:
Step lightly on the brake pedal,
move the cruise control switch to off, or
shift the transmission to NEUTRAL (N).
If road conditions cause the traction control
system to activate, cruise control will turn
off. SeeTraction Control System (TCS)
on page 309.
If the accelerator pedal is held for 60 seconds
or longer, cruise control will turn off.
Erasing Speed Memory
When you turn off the cruise control or the
ignition, your cruise control set speed memory
is erased.
Exterior Lamps
The control on the driver’s side of your instrument
panel operates the exterior lamps.
186

The exterior lamp control has four positions:
O(Off):Turn the knob to this position to turn off
all exterior lamps including the DRL. This
control will spring back to AUTO when released.
AUTO (Automatic):Turn the control to this
position to put the system into automatic headlamp
mode. AUTO mode, if enabled, will turn the
exterior lamps, including your DRL, on and off
automatically depending on how much light
is available outside the vehicle.
Your automatic lights may be disabled even if the
control is in the AUTO position.
To enable automatic lighting, do any of the
following:
Turn the headlamp control from AUTO to off
and release the control. It will return back to
the AUTO position by itself.
Turn the headlamp control from the parking
lamp position to AUTO.
Turn the headlamp control from the headlamp
position to AUTO.
Turn your engine off and then on again with
the headlamp control in AUTO.To disable automatic lighting, do any of the
following:
Turn the headlamp control from AUTO to off
and release the control. It will return back to
the AUTO position by itself.
Turn the headlamp control from AUTO to the
parking lamp position.
Turn the headlamp control from AUTO to the
headlamp position.
;(Parking Lamps):Turn the control to this
position to turn on the parking lamps, together with
the following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Roof Marker Lamps
Instrument Panel Lights
187

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.
