instrument panel HUMMER H3 2007 Owner's Guide

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) if
you have an automatic transmission.
The light sensor determines it is daytime.
When the DRL are on, no other lamps are on.
The instrument panel will not be lit up either.
For vehicles rst sold in Canada, if parking
lamps are manually turned on, DRL will stay on.
When it begins to get dark, the automatic
headlamp system will switch from DRL to the
headlamps.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
To turn off the DRL, seeExterior Lamps
on page 162.
Vehicles rst sold in Canada cannot turn
off DRL unless certain conditions are met.
SeeExterior Lamps on page 162.
Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system will turn on after the transmission
has been shifted from PARK (P) to DRIVE (D).
The headlamps, taillamps, sidemarker, parking
lamps, roof marker lamps, and the instrument panel
lights will turn on at normal brightness. The radio
lights will become more dim when the headlights
are off compared to when the headlights are on.
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 the 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
system 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 detects a change
in lighting lasting longer than the delay.
165

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 about one minute for the automatic headlamp
system to change to DRL if it is light outside.
During that delay, the instrument panel cluster
may not be as bright as usual. Make sure
the instrument panel brightness control is in
the full bright position. SeeInstrument Panel
Brightness on page 167.
Off-Road Lamps
The off-road lamps, if the vehicle has them,
provide auxiliary lighting when the vehicle is
used off road. These lamps are not intended to
be used in place of existing vehicle lighting.
The lamps are not to be used on any public street
or highway and are to be covered when not in
use. Check your state and local laws before
installing or using any auxiliary lighting. In some
states it may be necessary to remove the roof
lamps when operating the vehicle on the highway.The switches for the off-road lamps are located in
the center of the instrument panel below the climate
controls. One switch is used for the front lower-grille
mounted off-road lamps, if the vehicle has them,
and the other switch is used for the roof-mounted
off-road lamps, if the vehicle has them.
To use the lamps, remove the covers from the
lamps and press the switch to turn them on or
off. An indicator light on the switch will turn
on when the lamps are on.
Notice:Turning on the off-road lamps before
removing the lamp covers could damage the
off-road lamps and the covers. Always remove
the covers before turning on the off-road lamps.
The off-road lamps remain on even after the ignition
is turned off. The off-road lamp switch must be
pressed to turn them off.

Fog Lamps
Your vehicle has fog lamps. You can use them
for better vision in foggy or misty conditions.
Your parking lamps and/or low-beam headlamps
must be on for your fog lamps to work.
The fog lamp button
is located in the
exterior lamps control.
Press the button to turn the fog lamps on while
the headlamps or parking lamps are on. Press the
button again to turn them off. An indicator light
will glow in the button when the fog lamps are on.
Remember, fog lamps alone will not give off as
much light as your headlamps. Never use your fog
lamps in the dark without turning on the headlamps.
The fog lamps will go off whenever your
high-beam headlamps come on. When the high
beams go off, the fog lamps will come on again.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel
lights.
The thumbwheel for this feature is located next to
the exterior lamp control.
Turn the thumbwheel up or down to brighten or
dim the instrument panel lights and the radio
display. The instrument panel lights, cluster, and
radio display do not dim to complete darkness.
Turn the thumbwheel all the way up to turn
the dome lamps on.
Dome Lamp
The dome and footwell lamps will come on when
you open a door. The dome lamps are located
in the cargo and front area of the vehicle.
You can also turn the dome and footwell lamps
on by turning the thumbwheel, located next to
the exterior lamps control, all the way up. In this
position, the lamps will remain on whether a
door is opened or closed.
167

Battery Run-Down Protection
This feature shuts off the dome lamp if it is left
on for more than 20 minutes when the ignition
is in LOCK. This will help prevent your battery
from running down.
Accessory Power Outlet(s)
Your vehicle has accessory power outlets.
With accessory power outlets you can plug in
auxiliary electrical equipment such as a cellular
telephone or CB radio.
Your vehicle has two accessory power outlets
located on the lower part of the instrument panel
below the climate control system and there
may be one located in the rear cargo area.
A small cap must be pulled down to access an
accessory power outlet. When not using an outlet,
be sure to cover it with the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always
unplug electrical equipment when not in use
and do not plug in equipment that exceeds the
maximum amperage rating of 20 amperes.Certain electrical accessories may not be
compatible with the accessory power outlet and
could result in blown vehicle or adapter fuses.
If you experience a problem, see your dealer for
additional information on accessory power outlets.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should.
The repairs would not be covered by your
warranty. Do not use equipment exceeding
maximum amperage rating of 20 amperes.
Check with your dealer before adding electrical
equipment.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
Notice:Improper use of the power outlet
can cause damage not covered by your
warranty. Do not hang any type of accessory
or accessory bracket from the plug because
the power outlets are designed for accessory
power plugs only.

Recirculation is available in the bi-level, and vent
modes. Recirculation is not available while in
oor, oor/defog and defrost mode. If recirculation
is selected in these modes, the indicator will
ash three times indicating it is not available in
that mode. When the recirculation mode is turned
on, the air conditioning will turn on automatically.
H(Vent):Turn the right knob on the control
panel to this mode to direct air to the instrument
panel outlets.
\(Bi-Level):Turn the right knob on the control
panel to this mode to direct air to the instrument
panel outlets, and the remaining air to the
oor outlets and the defroster and side window
outlets. Cooler air is directed to the upper outlets
and warmer air to the oor outlets.
[(Floor):Turn the right knob on the control
panel to this mode to direct air to the oor outlets,
side window outlets, and defroster. Recirculation
is not available in this mode.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate
control system is used properly. There are
two modes to clear fog or frost from your
windshield and side windows. Use the defog mode
to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more
quickly. For best results, clear all snow and ice
from the windshield before defrosting.
/(Floor/Defog):Turn the right knob on the
control panel to this mode to direct the air to
the windshield, the side window outlets, and to
the oor outlets. When you select this mode, the
system runs the air conditioning system unless
the outside temperature is near freezing or below.
Recirculation is not available in this mode.
172

0(Defrost):Turn the right knob on the control
panel to this mode to direct most of the air to the
windshield, and the side window outlets. When
you select this mode, the system runs the air
conditioning system unless the outside temperature
is near or below freezing. Recirculation is not
available in this mode.
Do not drive the vehicle until all the windows
are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window when
the key is in the ignition and turned to ON.
=(Rear Defogger):Press the right knob on the
control panel to turn the rear window defogger
on or off. First press of this button will activate
the rear window defogger for 15 minutes and
each subsequent activation lasts seven and
one-half minutes.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the repairs
would not be covered by your warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.
Outlet Adjustment
Use the air outlets located in the center and
on the side of your instrument panel to direct
the airow.
Your vehicle has air outlets that allow you to
adjust the direction and amount of airow inside
the vehicle. Move the louvers up or down to
change the direction of the airow. Use the
thumbwheel under the outlets to change the
direction of the airow from left to right.
Operation Tips

Enable recirculation mode for maximum
air conditioning performance.
Clear away any ice, snow or leaves from the
air inlets at the base of the windshield that
may block the ow of air into your vehicle.
Use of non-GM approved hood deectors
may adversely affect the performance of
the system.
Keep the path under the front seats clear
of objects to help circulate the air inside
of your vehicle more effectively.
173

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running.
You will know how fast you are going, about how much fuel you have used, and many other things
you will need to know to drive safely and economically.

Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The
system checks the airbag’s electrical system for
malfunctions. The light tells you if there is an
electrical problem. The system check includes
the airbag sensors, the airbag modules, the wiring
and the crash sensing and diagnostic module.
For more information on the airbag systems, see
Airbag System on page 65.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should
go out. This means
the system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays
on after you start your vehicle.
The airbag readiness light should ash for a
few seconds when you turn the ignition key to ON.
If the light does not come on then, have it xed
so it will be ready to warn you if there is a problem.
178

Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your instrument panel has a passenger airbag
status indicator.
When the ignition key is turned to ON or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. Then,
after several more seconds, the status indicator
will light either ON or OFF, or either the on
or off symbol to let you know the status of the
right front passenger’s frontal airbag.
If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger’s frontal airbag is
enabled (may inate).{CAUTION:
If the on indicator comes on when you have
a rear-facing child restraint installed in the
right front passenger’s seat, it means that
the passenger sensing system has not
turned off the passenger’s frontal airbag.
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
