display HUMMER H2 2007 Owners Manual

A non-scrubbing action, wet-type cleaner which
uses a cassette with a fabric belt to clean the tape
head can be used. This type of cleaning cassette
will not eject on its own. A non-scrubbing action
cleaner may not clean as thoroughly as the
scrubbing type cleaner. The use of a non-scrubbing
action, dry-type cleaning cassette is not
recommended.
After the player is cleaned, press and hold the
eject button for ve seconds to reset the CLEAN
indicator. The radio will display --- or CLEANED to
show the indicator was reset.
Cassettes are subject to wear and the sound
quality may degrade over time. Always make sure
the cassette tape is in good condition before
the tape player is serviced.Care of Your CDs and DVDs
Handle CDs and DVDs carefully. Store them in
their original cases or other protective cases and
away from direct sunlight and dust. The CD
and DVD player scans the bottom surface of the
disc. If the surface of a CD or DVD is damaged,
such as cracked, broken, or scratched, the CD or
DVD will not play properly or not at all. If the
surface of a CD or DVD is soiled, take a soft, lint
free cloth or dampen a clean, soft cloth in a
mild, neutral detergent solution mixed with water,
and clean it. Make sure the wiping process
starts from the center to the edge. If a dampened
cloth was used to clean the disc, dry it with a
dry cotton cloth.
Do not touch the bottom side of a CD or DVD
while handling it; this could damage the surface.
Pick up CDs or DVDs by grasping the outer edges
or the edge of the hole and the outer edge.
299

Care of the CD and DVD Player
The use of CD or DVD lens cleaners for CDs or
DVDs are not advised, due to the risk of
contaminating the lens of the CD optics with
lubricants internal to the CD or DVD mechanism.
Fixed Mast Antenna
The xed mast antenna can withstand most car
washes without being damaged. If the mast should
ever become slightly bent, straighten it out by
hand. If the mast is badly bent, replace it.
Check occasionally to make sure the mast is still
tightened.
XM™ Satellite Radio
Antenna System
The XM™ Satellite Radio antenna is located on
the roof of your vehicle. Keep this antenna clear of
snow and ice build up for clear radio reception.
If your vehicle has a sunroof, the performance of
the XM™ system may be affected if the sunroof
is open.Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure the XM™ Satellite Radio antenna is
not obstructed.
Chime Level Adjustment
The radio is used to adjust the vehicle’s chime
level. To change the volume level of the chime,
press and hold pushbutton 6 with the ignition
on and the radio power off. The volume level will
change from the normal level to loud, and
LOUD CHIME will appear on the radio display.
To change back to the default or normal setting,
press and hold pushbutton 6 again. The volume
level will change from the loud level to normal,
and NORMAL CHIME will appear on the
radio display. Removing the radio and not
replacing it with a factory radio or chime module
will disable vehicle chimes.
300

You may also hear the release of air similar to a
hissing sound during suspension operation.
This is normal.
Load leveling will not function normally with the
inator hose attached to the inator outlet.
Remove the inater hose from the outlet when
it is not in use. SeeAccessory Inator on
page 466.
Overload and Overheat Protection
Overload protection is designed to protect the air
suspension system and is an indication to the
driver that the vehicle is overloaded.
If the rear suspension remains at a low height, the
rear axle load has exceeded GAWR (Gross Axle
Weight Rating). When the overload protection
mode is activated, the compressor operates forabout 30 seconds to one minute without raising the
vehicle depending on the amount of overload.
This will continue each time the ignition is turned on
until the rear axle load is reduced below GAWR.
If the total rear GAWR (Gross Axle Weight Rating)
is reached, the suspension may be slightly less
than level. This is normal and does not mean there
is a problem with the air suspension.
If the system overheats due to normal operation,
the SERVICE AIR SUSPENSION message
will not be displayed on the DIC, but the system
will shut down and stop all leveling functions until it
cools down. If the system overheats and sets
the SERVICE AIR SUSPENSION message in the
DIC, then there is a fault. SeeDIC Warnings
and Messages on page 226for more information.

{CAUTION:
If you spill fuel and then something
ignites it, you could be badly burned.
Fuel can spray out on you if you open the
fuel cap too quickly. This spray can
happen if your tank is nearly full, and is
more likely in hot weather. Open the fuel
cap slowly and wait for any hiss noise to
stop. Then unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or overll
the tank and wait a few seconds after you have
nished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon as
possible. SeeWashing Your Vehicle on page 495.When replacing the fuel cap, turn it clockwise
until it clicks. Make sure the cap is fully installed.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed.
This would allow fuel to evaporate into the
atmosphere. SeeMalfunction Indicator Lamp
on page 215.
The TIGHTEN FUEL CAP message will be
displayed on the Driver Information Center (DIC)
if the fuel cap is not properly installed.
SeeDIC Warnings and Messages on page 226
for more information.

How to Reset the Engine Oil
Life System
The Engine Oil Life System calculates when to
change your engine oil and lter based on vehicle
use. Anytime your oil is changed, reset the system
so it can calculate when the next oil change is
required. If a situation occurs where you change
your oil prior to a CHANGE ENGINE OIL message
being turned on, reset the system.
To reset the CHANGE ENGINE OIL message,
see “Engine Oil Life System” underDIC Operation
and Displays on page 222for vehicles that
have the DIC, or do the following:
1. Turn the ignition key to RUN with the engine off.
2. Fully press and release the accelerator pedal
slowly three times within ve seconds.
If the OIL LIFE RESET message ashes for
10 seconds, the system is resetting.
3. Turn the key to LOCK.
If the CHANGE ENGINE OIL message comes
back on when you start your vehicle, the engine oil
life system has not reset. Repeat the procedure.
If it still does not reset, see your dealer for service.
What to Do with Used Oil
Used engine oil contains certain elements that
may be unhealthy for your skin and could
even cause cancer. Do not let used oil stay on
your skin for very long. Clean your skin and nails
with soap and water, or a good hand cleaner.
Wash or properly dispose of clothing or rags
containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil
products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil
from the lter before disposal. Never dispose of oil
by putting it in the trash, pouring it on the
ground, into sewers, or into streams or bodies of
water. Instead, recycle it by taking it to a place
that collects used oil. If you have a problem
properly disposing of your used oil, ask your
dealer, a service station, or a local recycling
center for help.

Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
REDUCED ENGINE POWER message is
displayed, an overheat protection mode which
alternates ring groups of cylinders helps prevent
engine damage. In this mode, you will notice a
loss in power and engine performance. This
operating mode allows your vehicle to be driven to
a safe place in an emergency. Driving extended
miles (km) and/or towing a trailer in the overheat
protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss, change the oil and reset the oil life
system. SeeEngine Oil on page 404.
Cooling System
When you decide it is safe to lift the hood, here is
what you will see:
A. Coolant Surge Tank
B. Coolant Surge Tank Pressure Cap
C. Engine Cooling Fan
If the coolant inside the coolant surge tank is
boiling, do not do anything else until it cools down.
The vehicle should be parked on a level surface.

Windshield Washer Fluid
What to Use
When you need windshield washer uid, be sure to
read the manufacturer’s instructions before use. If
you will be operating your vehicle in an area where
the temperature may fall below freezing, use a uid
that has sufficient protection against freezing.
Adding Washer Fluid
Your vehicle has a message that comes on when
the washer uid is low. The message is
displayed for 15 seconds at the start of each
ignition cycle if the uid is low. When the CHECK
WASHER FLUID message is displayed, you
will need to add washer uid to the windshield
washer uid reservoir. SeeDIC Warnings
and Messages on page 226for more information.
Open the cap with the
washer symbol on it.
Add washer uid
until the tank is full. See
Engine Compartment
Overview on page 402
for reservoir location.Notice:
When using concentrated washer uid,
follow the manufacturer’s instructions
for adding water.
Do not mix water with ready-to-use washer
uid. Water can cause the solution to
freeze and damage your washer uid tank
and other parts of the washer system.
Also, water does not clean as well
as washer uid.
Fill your washer uid tank only
three-quarters full when it is very cold.
This allows for expansion if freezing
occurs, which could damage the tank if it
is completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage
your washer system and paint.
