2007 HUMMER H2 lock

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.

Brake and Accelerator Operation
Techniques for Off-Road Driving
For logs, walls, rocks, severe ditches,
hills, sand, etc.
1. Bring the vehicle to a complete stop. Do not
rev the engine.
2. Select the proper transmission and transfer
case gear range; usually FIRST (1) gear,
4LO LOCK for such obstacles.
3. If wheel spin is experienced, maintain steady
throttle, with your foot off the brake pedal, to
allow the Traction Control System (TCS)
to control the wheel spin. TCS will not operate
if the brakes are applied, even slightly.
4. If wheel spin cannot be controlled by the
system, fully press the brake pedal with
your left foot so all wheel spin is halted.
5. Back away from the obstacle so that a new
approach can be tried.
6. As the rst wheel crosses the obstacle, be
prepared to alternate the brake and
accelerator pedal to maintain control and
avoid tire drop-off from obstacles. Repeat this
process for the other wheels.
For mounds, washouts, loose up-hill
slopes, ditches, etc.
When wheel spin occurs as the vehicle is moving,
the driver may notice a slight shaking or
shuddering of the vehicle. This should be stopped
as soon as possible to prevent damage to
vehicle components. This is the indication that a
loss of traction is occurring on this terrain.
The operator should:
1. Reduce speed and apply the brakes.
2. Assess the terrain properly and adjust vehicle
speed and gear ranges accordingly: 4HI
position for higher speeds and 4LO LOCK for
more torque and lower speeds. Transmission
FIRST (1) gear is generally recommended.
3. Apply slight pressure to the brake when the
shaking or shuddering sensation is felt,
keeping the vehicle moving in a controlled
manner.
4. Be prepared to alternate between braking and
accelerating through the adverse terrain.

Log Crossing
Using the proper technique, your vehicle will cross
logs up to 10 inches (25.4 cm) in diameter.
Approach the log at approximately a 15° angle (A)
with the transmission in FIRST (1) and the
transfer case in 4LO LOCK and “walk” your vehicle
over, one tire at a time. It may be necessary to
modulate your brake pedal and accelerator
to avoid spin-out. Ease the vehicle down from the
log with your brake.
Driving on Off-Road Hills
Off-road driving often takes you up, down, or
across a hill. Driving safely on hills requires good
judgment and an understanding of what your
vehicle can and cannot do. There are some hills
that simply cannot be driven, no matter how
well built the vehicle.
{CAUTION:
Many hills are simply too steep for any
vehicle. If you drive up them, you will
stall. If you drive down them, you cannot
control your speed. If you drive across
them, you will roll over. You could be
seriously injured or killed. If you have any
doubt about the steepness, do not drive
the hill.
327

Approaching a Hill
When you approach a hill, you need to decide if it is
one of those hills that is just too steep to climb,
descend, or cross. Steepness can be hard to judge.
On a very small hill, for example, there may be a
smooth, constant incline with only a small change in
elevation where you can easily see all the way to
the top. On a large hill, the incline may get steeper
as you near the top, but you may not see this
because the crest of the hill is hidden by bushes,
grass, or shrubs.
Here are some other things to consider as you
approach a hill:
Is there a constant incline, or does the hill get
sharply steeper in places?
Is there good traction on the hillside, or will
the surface cause tire slipping?
Is there a straight path up or down the hill so
you will not have to make turning maneuvers?
Are there obstructions on the hill that can
block your path, such as boulders, trees, logs,
or ruts?
What is beyond the hill? Is there a cliff, an
embankment, a drop-off, a fence? Get out and
walk the hill if you do not know. It is the smart
way to nd out.
Is the hill simply too rough? Steep hills often
have ruts, gullies, troughs, and exposed rocks
because they are more susceptible to the
effects of erosion.
Driving Uphill
Once you decide you can safely drive up the hill,
you need to take some special steps:
Use transmission and transfer case low gear
and get a rm grip on the steering wheel.
Get a smooth start up the hill and try to
maintain your speed. Do not use more power
than you need, because you do not want
your wheels to start spinning or sliding.
Let the traction system work to control any
wheel slippage. The traction control system
allows for moderate wheel spin with some
capability to dig in and power up the hill.

Q:What should I do if my vehicle stalls, or is
about to stall, and I cannot make it up
the hill?
A:If this happens, there are some things you
should do, and there are some things you
must not do. First, here is what youshoulddo:
Push the brake pedal to stop the vehicle
and keep it from rolling backwards. Also, apply
the parking brake.
If your engine is still running, shift the
transmission to REVERSE (R), release the
parking brake, and slowly back down the hill in
REVERSE (R).
If your engine has stopped running, you will
need to restart it. With the brake pedal
pressed and the parking brake still applied,
shift the transmission to PARK (P) and restart
the engine. Then, shift to REVERSE (R),
release the parking brake, and slowly back
down the hill as straight as possible in
REVERSE (R).
As you are backing down the hill, put your left
hand on the steering wheel at the 12 o’clock
position. This way, you will be able to tell
if your wheels are straight and maneuver as
you back down. It is best that you back
down the hill with your wheels straight rather
than in the left or right direction. Turning
the wheel too far to the left or right will
increase the possibility of a rollover.
Here are some things youmust notdo if you stall,
or are about to stall, when going up a hill:
Never attempt to prevent a stall by shifting
into NEUTRAL (N) to rev-up the engine
and regain forward momentum. This will not
work. Your vehicle will roll backwards
very quickly and you could go out of control.
Instead, apply the regular brake to stop
the vehicle. Then apply the parking brake.
Shift to REVERSE (R), release the parking
brake, and slowly back straight down.
Never attempt to turn around if you are about
to stall when going up a hill. If the hill is steep
enough to stall your vehicle, it is steep
enough to cause you to roll over if you turn
around. If you cannot make it up the hill, you
must back straight down the hill.
330

Q:Suppose, after stalling, I try to back down
the hill and decide I just cannot do it.
What should I do?
A:Set the parking brake, put your transmission
in PARK (P) and turn off the engine. Leave
the vehicle and go get some help. Exit on the
uphill side and stay clear of the path the
vehicle would take if it rolled downhill. Do not
shift the transfer case to NEUTRAL when
you leave the vehicle. Leave it in some gear.
{CAUTION:
Shifting the transfer case to NEUTRAL
can cause your vehicle to roll even if the
transmission is in PARK (P). This is
because the NEUTRAL position on the
transfer case overrides the transmission.
You or someone else could be injured.
If you are going to leave your vehicle,
set the parking brake and shift the
transmission to PARK (P). But do not shift
the transfer case to NEUTRAL. Leave the
transfer case in the 4 HI, 4 HI Lock, or
4 LO Lock position.

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
(13.5
Y) with the tool as shown.

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 (50
Y).
Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to
be impaired — by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce the
glare from headlamps behind you.
Since you cannot see as well, you may need
to slow down and keep more space between
you and other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe
place and rest.
