HUMMER H2 2008 Owners Manual

Front Mounted Receiver
Your vehicle is equipped with a front mounted receiver.
You can use the receiver with a power winch platform
(described later in this section) or with other
accessories.
Never use the front mounted receiver to tow a trailer.
You can use the front mounted receiver to tow your
vehicle behind another. SeeRecreational Vehicle
Towing on page 4-51.
Power Winch Platform
You can use the power winch platform (if equipped)
with an aftermarket winch. Connect the winch to
the platform and wiring to the vehicle following the
winch manufacturer’s guidelines.
Notice:Do not use the winch platform to winch at
a tension of more than 9,000 lbs. (4 082 kg). This
would damage your vehicle’s frame. This damage
would not be covered by your vehicle’s warranty.
If you are using a winch to pull out another vehicle,
follow the winch manufacturer’s guidelines and observe
the following to prevent damage to your vehicle:
If possible, have your vehicle anchored from the
opposite side of the winch to a solid, immovable
object.
If winching from the front, use both of the rear
recovery loops. If winching from the rear, use both
of the front recovery loops.
Put your transmission in NEUTRAL (N).
Use your regular brakes to hold your vehicle in
place and block the wheels to keep the vehicle
from moving.
4-43

Notice:Using a power winch with the transmission
in gear to pull out another vehicle may damage
the transmission. When operating a power winch,
always leave the transmission in NEUTRAL (N).
Notice:Driving your vehicle through an automatic
car wash with the winch installed, can cause
damage to your vehicle and the car wash. Always
remove the winch from your vehicle before using an
automatic car wash. SeeWashing Your Vehicle
on page 5-103for more information.
If you are using a winch to pull out your own vehicle,
follow the winch manufacturer’s guidelines for self
recovery and observe the following to prevent damage
to your vehicle:
Do not self recover your vehicle by wrapping the
winch cable around an object (such as a pulley
block or tree) and attaching it back to your vehicle’s
recovery loops.
Always attach the winch cable directly to a solid
anchor directly in front of your vehicle to achieve
a straight line pull.
Loading Your Vehicle
It is very important to know how much weight your
vehicle can carry. This weight is called the vehicle
capacity weight and includes the weight of all
occupants, cargo, and all nonfactory-installed
options. Two labels on your vehicle show how much
weight it may properly carry, the Tire and Loading
Information label and the Certication/Tire label.
{CAUTION:
Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do,
parts on your vehicle can break, and it
can change the way your vehicle handles.
These could cause you to lose control
and crash. Also, overloading can shorten
the life of your vehicle.
4-44

Tire and Loading Information Label
A vehicle specic Tire and Loading Information
label is attached to the center pillar (B-pillar).
With the driver’s door open, you will nd the
label attached below the door lock post (striker).
The tire and loading information label shows
the number of occupant seating positions (A),
and the maximum vehicle capacity weight (B) in
kilograms and pounds.The Tire and Loading Information label also shows
the size of the original equipment tires (C) and
the recommended cold tire ination pressures (D).
For more information on tires and ination see
Tires on page 5-55andInflation - Tire Pressure on
page 5-61.
There is also important loading information on the
vehicle Certication/Tire label. It tells you the
Gross Vehicle Weight Rating (GVWR) and
the Gross Axle Weight Rating (GAWR) for the
front and rear axle. See “Certication/Tire Label”
later in this section.

Steps for Determining Correct Load Limit
1.Locate the statement “The combined weight
of occupants and cargo should never
exceed XXX kg or XXX lbs” on your vehicle’s
placard.
2.Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.
4.The resulting gure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be ve 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs (1400−750 (5 x 150) = 650 lbs).
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle.
That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
6.If your vehicle will be towing a trailer, the load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity of your vehicle.
SeeTowing a Trailer on page 4-55for important
information on towing a trailer, towing safety
rules and trailering tips.

information label for specic information about
your vehicle’s capacity weight and seating
positions. The combined weight of the driver,
passengers and cargo should never exceed your
vehicle’s capacity weight.
Certication/Tire Label
A vehicle specic Certication/Tire label is
attached to the rear edge of the driver’s door.
Example 3
4-48

The label shows the gross weight capacity of your
vehicle. This is called the GVWR (Gross Vehicle
Weight Rating). The GVWR includes the weight of
the vehicle, all occupants, fuel, and cargo.
The Certication/Tire label also tells you the
maximum weights for the front and rear axles,
called Gross Axle Weight Rating (GAWR).
To nd out the actual loads on your front and rear
axles, you need to go to a weigh station and
weigh your vehicle. Your dealer can help you with
this. Be sure to spread out your load equally on
both sides of the centerline.
Never exceed the GVWR for your vehicle, or the
GAWR for either the front or rear axle.
And, if you do have a heavy load, you should
spread it out.
{CAUTION:
Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do,
parts on your vehicle can break, and it
can change the way your vehicle handles.
These could cause you to lose control
and crash. Also, overloading can shorten
the life of your vehicle.
Your warranty does not cover parts or components
that fail because of overloading.
The label will help you decide how much cargo
and installed equipment your truck can carry.
Using heavier suspension components to
get added durability might not change your weight
ratings. Ask your dealer to help you load your
vehicle the right way.
4-49

If you put things inside your vehicle — like
suitcases, tools, packages, or anything else — they
go as fast as the vehicle goes. If you have to stop or
turn quickly, or if there is a crash, they will keep
going.
{CAUTION:
Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the cargo area of your
vehicle. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
Do not leave an unsecured child
restraint in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down
unless you need to.There is also important loading information for
off-road driving in this manual. See “Loading Your
Vehicle for Off-Road Driving” underOff-Road
Driving on page 4-13.
Add-On Equipment
When you carry removable items, you may need
to put a limit on how many people you can
carry inside your vehicle. Be sure to weigh your
vehicle before you buy and install the new
equipment.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the front or rear axle.
The Cargo Weight Rating (CWR) is the maximum
weight of the load your vehicle can carry.
It does not include the weight of the people inside.
But you can gure about 150 lbs (68 kg) for
each seat.
The total cargo load must not be more than your
vehicle’s CWR.

Towing
Towing Your Vehicle
Consult your dealer/retailer or a professional towing
service if you need to have your disabled vehicle towed.
SeeRoadside Assistance Program on page 7-6.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle – such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as “dinghy towing” (towing your
vehicle with all four wheels on the ground) and “dolly
towing” (towing your vehicle with two wheels on
the ground and two wheels up on a device known as
a “dolly”).With the proper preparation and equipment, many
vehicles can be towed in these ways. See “Dinghy
Towing” and “Dolly Towing,” following.
Here are some important things to consider before you
do recreational vehicle towing:
What’s the towing capacity of the towing vehicle?
Be sure you read the tow vehicle manufacturer’s
recommendations.
How far will you tow? Some vehicles have
restrictions on how far and how long they can tow.
Do you have the proper towing equipment?
See your dealer or trailering professional for
additional advice and equipment recommendations.
Is your vehicle ready to be towed? Just as you
would prepare your vehicle for a long trip, you’ll
want to make sure your vehicle is prepared to be
towed. SeeBefore Leaving on a Long Trip on
page 4-34.
4-51

Dinghy Towing
Use the following procedure to tow your vehicle:
1. Shift the transmission to PARK (P).
2. Turn the engine off, but leave the ignition in
ACCESSORY.
3. Firmly set the parking brake.
4. Securely attach the vehicle being towed to the
tow vehicle.
{CAUTION:
Shifting a full-time four-wheel-drive vehicle’s
transfer case into NEUTRAL can cause your
vehicle to roll even if the transmission is in
PARK (P). You or others could be injured.
Make sure the parking brake is rmly set
before you shift the transfer case to NEUTRAL.
5. Shift the transfer case to NEUTRAL (N). See
Full-Time Four-Wheel Drive on page 2-36for
the proper procedure to select the NEUTRAL
position for your vehicle.6. Release the parking brake only after the vehicle
being towed is rmly attached to the towing
vehicle. You can use your vehicle’s front mounted
receiver with the proper accessories to tow it.
See “Front Mounted Receiver” underIf Your Vehicle
is Stuck in Sand, Mud, Ice, or Snow on page 4-39.
7. Turn the ignition to ACCESSORY.
8. Disconnect the battery if you are going to tow for
long distances or long periods of time.
When towing your vehicle for extended periods of time,
start your vehicle as often as possible to prevent
battery drain. This should only be done when the tow
vehicle is parked.Dolly Towing
Your vehicle cannot be dolly towed. If you must tow
your vehicle behind another, use the dinghy towing
procedure listed previously.
Notice:Dolly towing your vehicle will damage
drivetrain components. Do not dolly tow your
vehicle.
