2007 HUMMER H2 ignition

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.

Off-Road Lamps
Notice:If you drive your vehicle through an
automatic car wash that does not have enough
clearance for any roof-mounted accessories
(such as off-road lamps or a roof basket)
on your vehicle, you can damage your vehicle.
To avoid damaging your vehicle in a car
wash, remove any roof-mounted accessories if
you can, and do not use an automatic car
wash while roof-mounted accessories are on
your vehicle. SeeWashing Your Vehicle
on page 495for more information.
The off-road lamps, if equipped, provide auxiliary
lighting when your vehicle is used off road.
These lamps are not intended to be used in
conjunction with, or 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 button for the off-road lamps is located in the
overhead console.
To use the lamps, be sure the engine is running.
Remove the covers from the lamps and press
the button to turn them on. Press the button again
to turn them off. An indicator light will glow near
the button 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
return the lamps to the upright position
and remove the covers before turning on the
off-road lamps.
The off-road lamps will remain on even after the
ignition is turned off. The off-road lamps button
must be pressed to turn them off.

the driver when backing up by displaying a view
of the area behind the vehicle. When the

For more information on the automatic dimming,
compass, and temperature features of the mirror,
seeAutomatic Dimming Rearview Mirror with
Compass and Temperature Display on page 139.
{CAUTION:
The Rear Vision Camera (RVC)
system does not replace driver vision.
RVC does not:
Detect objects that are outside the
camera’s eld of view, below the
bumper, or underneath the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
Do not back the vehicle by only looking at
the rear vision camera screen, or use the
screen during longer, higher speed
backing maneuvers or where there could
be cross-traffic. Your judged distances
using the screen will differ from actual
distances.
So if you do not use proper care before
backing up, you could hit a vehicle, child,
pedestrian, bicyclist, or pet, resulting in
vehicle damage, injury, or death. Even
though the vehicle has the RVC system,
always check carefully before backing up
by checking behind your vehicle.

Speedometer and Odometer
Your speedometer lets you see your speed in
both miles per hour (mph) and kilometers
per hour (km/h).
Your vehicle’s odometer works together with the
driver information center. You can set a Trip A and
Trip B odometer. See “Trip Information” under
DIC Operation and Displays on page 222.
The odometer mileage can be checked without the
vehicle running. Simply press the trip stem on
the instrument panel cluster.
If your vehicle ever needs a new odometer
installed, the new one will be set to the correct
mileage total of the old odometer.
Trip Odometer
The trip odometer can tell you how far your
vehicle has been driven since you last set the trip
odometer to zero.
Press the reset button, located on the instrument
panel cluster next to the trip odometer display,
to toggle between the trip odometer and the
regular odometer. Holding the reset button for
approximately one second while the trip odometer
is displayed will reset it.To display the odometer reading with the ignition
off, press the reset button.
Tachometer

belt light will also be provided and stay on for
several seconds, then it will ash for several more.
You should buckle your seat belt.
This chime and light will

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
system, seeAirbag System on page 77.
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 RUN.
If the light doesn’t come on then, have it xed so it
will be ready to warn you if there is a problem.
207

{CAUTION:
If the airbag readiness light ever comes
on when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could inate even
though the switch is off. If this ever
happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in the right front
passenger’s seat) until you have your
vehicle serviced. SeeAirbag Off Switch on
page 84, for more on this, including
important safety information.
Charging System Light
The charging system
light will come on briey
when the ignition is on,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving,
you may have a problem with the charging system.
It could indicate that you have problems with a
generator drive belt, or another electrical problem.
Have it checked right away. Driving while this
light is on could drain the battery.
When this light comes on the DIC will also display
the SERVICE BATTERY CHARGING SYSTEM
message. SeeDIC Warnings and Messages
on page 226for more information.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner.
