2005 HUMMER H2 Owners Manual

U-Type Side Steps
The following instructions show how to install the
optional U-type steps. If you want to remove them, just
reverse the instructions:
1. Start with the side step brackets pointing up and
away from you, or just make sure the HUMMER
logo faces up.
2. For the front step, use the rst and third brackets
on the vehicle from the front tire. For the rear step,
use the rst and third brackets on the vehicle
from the rear tire.
You will notice that the side steps have pins on
both sides of the step brackets. This is because the
steps are interchangeable between front/back
and the driver/passenger sides of the vehicle. Use
the pins as follows:
Driver Side:Look at the side step with the
HUMMER logo facing you. You will use the pins
which are on the right side of each side step
bracket. This works for the front or rear of
the vehicle.
Passenger Side:Look at the side step with the
HUMMER logo facing you. You will use the pins
which are on the left side of each side step
bracket. This works for the front or rear of
the vehicle.3. Guide the pins on the side step brackets into the
holes in the vehicle’s rocker panel protector
brackets. If you have difficulty doing this, it may
help to have someone hold up the step while you
guide the pins into the holes.
You will be guiding three pins into the holes with
the fourth hole in the vehicle’s rocker panel protector
brackets empty until the next step.

4. Thread the knob through the remaining hole — rst
into the rocker panel protector and then into the
threaded hole in the side step bracket.
Notice:Threading the knob into the side step and
then into the rocker panel will not secure the step.
The step could fall off the vehicle and be damaged.
Always thread the knob through the rocker panel
rst. After the knob is installed, try moving the step
left and right to be sure the step is secure.5. Hand-tighten the knob by turning it clockwise until it
is seated against the rocker panel protector bracket
and then tighten it to 10 lb ft (13.5Y) with the
tool as shown.
4-18

6. Once the knob is
torqued, install the
cotter pin through the
hole in the end of the
knob’s threaded shaft.
This will help prevent the knob from coming completely
loose and falling out.Tubular Side Steps
The driver’s side of the vehicle is shown with the body
removed for clarity. To remove a step:
1. Remove the nuts and bolts attaching the step to
the vehicle.
2. Remove the step from the vehicle.
4-19

To install a step:
1. Before installing the bolts:
Remove all traces of the original adhesive patch.
Clean the threads of the bolts with denatured
alcohol or equivalent and allow threads to dry.
Apply Threadlocker (GM Part No. 12345382, in
Canada 10953489) or equivalent.
2. Install the side step to the vehicle. You may need
someone to assist you in the installation.
3. Install the nuts and bolts for the two inner brackets
rst, but do not tighten them.
4. Using a level, make sure the step is level in
relationship to the vehicle. Then, tighten the
inner bracket nuts and bolts.
5. Install the other nuts and bolts. Tighten all nuts and
bolts to 39 lb ft (50Y).
Loading Your Vehicle for
Off-Road Driving
There are some important things to remember about
how to load your vehicle.
The heaviest things should be on the load oor and
forward of your rear axle. Put heavier items in the
rear area, as far forward as you can.
Be sure the load is secured properly, so driving on
the off-road terrain does not toss things around.
4-20

{CAUTION:
Cargo on the load oor piled higher than
the seatbacks can be thrown forward
during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.
Unsecured cargo on the load oor can be
tossed about when driving over rough
terrain. You or your passengers can be
struck by ying objects. Secure the
cargo properly.
Heavy loads on the roof raise the vehicle’s
center of gravity, making it more likely to
roll over. You can be seriously or fatally
injured if the vehicle rolls over. Put heavy
loads inside the cargo area, not on the
roof. Keep cargo in the cargo area as far
forward and low as possible.
You will nd other important information in this manual.

Environmental Concerns
Off-road driving can provide wholesome and satisfying
recreation. However, it also raises environmental
concerns. We recognize these concerns and urge every
off-roader to follow these basic rules for protecting
the environment:
Always use established trails, roads and areas that
have been specially set aside for public off-road
recreational driving; obey all posted regulations.
Avoid any driving practice that could damage
the environment — shrubs, owers, trees,
grasses — or disturb wildlife (this includes
wheel-spinning, breaking down trees or
unnecessary driving through streams or over
soft ground).
Always carry a litter bag — make sure all refuse is
removed from any campsite before leaving.
Take extreme care with open res (where
permitted), camp stoves and lanterns.
Never park your vehicle over dry grass or other
combustible materials that could catch re from
the heat of the vehicle’s exhaust system.
4-21

Traveling to Remote Areas
It makes sense to plan your trip, especially when going
to a remote area. Know the terrain and plan your
route. You are much less likely to get bad surprises.
Get accurate maps of trails and terrain. Try to learn of
any blocked or closed roads.
It is also a good idea to travel with at least one other
vehicle. If something happens to one of them, the other
can help quickly.
Does your vehicle have a winch? If so, be sure to read
the winch instructions. In a remote area, a winch
can be handy if you get stuck. But you will want to know
how to use it properly.
High Mobility Characteristics
The HUMMER H2 has a 10 inch (25.4 cm) running
ground clearance (A) and a 9 inch (22.8 cm) axle
to ground clearance (B) while maintaining a low
silhouette and a low center of gravity.
4-22

The HUMMER H2 has an approximate approach
angle (A) of 42° and a departure angle (B) of 37°,
depending on suspension packages.
Design specications required a minimum gradeability of
60% (31°) slope, with the vehicle fully loaded, on high
friction surfaces at 6 mph (9.7 km/h). The vehicle is
expected to traverse this grade only for short durations.
Never stop and idle the vehicle or park it on this grade.
4-23

Also, your vehicle should be able to traverse a 40%
(22°) side slope at 6 mph (9.7 km/h) while fully loaded
on high friction surfaces.Your vehicle can climb a 16 inch (40.6 cm) vertical step.
Step climbing is best done by approaching the step at
an angle rather than straight on.
