ABS HUMMER H3 2009 User Guide

{CAUTION
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they could get so hot that
they would not work well. You
would then have poor braking or
even none going down a hill. You
could crash. Always have the
engine running and the vehicle in
gear when going downhill.
Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
Top of hills: Be alert — something
could be in your lane (stalled car,
accident).
Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
SeeOff-Road Driving on page 4-13
for information about driving
off-road.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 32°F
(0°C) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently
so traction is not lost. Accelerating
too quickly causes the wheelsto spin and makes the surface
under the tires slick, so there is even
less traction.
Try not to break the fragile traction. If
you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
TheTraction Control System (TCS)
on page 4-7improves the ability
to accelerate on slippery roads, but
slow down and adjust your driving
to the road conditions. When driving
through deep snow, turn off the
traction control system to help
maintain vehicle motion at lower
speeds.
TheAntilock Brake System (ABS)
on page 4-5improves vehicle
stability during hard stops on a
slippery roads, but apply the brakes
sooner than when on dry pavement.

Parking on Hills
{CAUTION
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a at surface.
If parking the rig on a hill:
1. Press the brake pedal, but do
not shift into P (Park) yet for
vehicles with an automatic
transmission, or into gear for
vehicles with a manual
transmission. Turn the wheels
into the curb if facing downhill or
into traffic if facing uphill.2. Have someone place chocks
under the trailer wheels.
3. When the wheel chocks are in
place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal.
Then apply the parking brake and
shift into P (Park) for vehicles
with an automatic transmission or
into gear for vehicles with a
manual transmission.
5. Release the brake pedal.
Leaving After Parking on
a Hill
The vehicle has a Hill Start Assist
feature, which may be useful
when stopped on a grade. See
Braking on page 4-3for more
information.
1. Apply and hold the brake pedal
while you:
start the engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is
clear of the chocks.
4. Stop and have someone pick up
and store the chocks.

When reinstalling the jack and
jack tool bag, make sure the jack
base is securely seated behind
the tabs in the swing-gate.4. Reinstall the wing nut retainer to
fasten the jack and tool bag in
the storage compartment.
Make sure that the wing nut
passes through the tool bag and
the jack before tightening it.
5. Turn the wing nut retainer
clockwise to secure.
6. Reinstall the compartment cover
by inserting the locator tabs in
the holes in the swing-gate.
Push the latches down to secure.
Service and Appearance Care 5-79

Laundry detergents or
dishwashing soaps with
degreasers can leave residue
that streaks and attracts dirt.
For liquid cleaners, about
20 drops per gallon (3.78 L) of
water is a good guide. Use
only mild, neutral-pH soaps.
Too much cleaner that saturates
the upholstery.
Organic solvents such as naptha,
alcohol, etc. that can damage the
vehicle’s interior.
Fabric/Carpet
Use a vacuum cleaner with a soft
brush attachment frequently to
remove dust and loose dirt.
A canister vacuum with a beater bar
in the nozzle may only be used
on oor carpet and carpeted oor
mats. For any soil, always try
to remove it rst with plain water orclub soda. Before cleaning, gently
remove as much of the soil as
possible using one of the following
techniques:
For liquids: gently blot the
remaining soil with a paper towel.
Allow the soil to absorb into
the paper towel until no more
can be removed.
For solid dry soils: remove as
much as possible and then
vacuum.
To clean:
1. Saturate a lint-free, clean white
cloth with water or club soda.
2. Wring the cloth to remove excess
moisture.
3. Start on the outside edge of the
soil and gently rub toward the
center. Continue cleaning, using
a clean area of the cloth each
time it becomes soiled.4. Continue to gently rub the soiled
area until the cleaning cloth
remains clean.
5. If the soil is not completely
removed, use a mild soap
solution and repeat the cleaning
process that was used with
plain water.
If any of the soil remains, a
commercial fabric cleaner or spot
lifter may be necessary. When
a commercial upholstery cleaner or
spot lifter is to be used, test a
small hidden area for colorfastness
rst. If the locally cleaned area
gives any impression that a ring
formation may result, clean
the entire surface.
After the cleaning process has been
completed, a paper towel can be
used to blot excess moisture
from the fabric or carpet.
