traction control HUMMER H3 2009 Owner's Manual

Rocking Your Vehicle to
Get It Out
Turn the steering wheel left and
right to clear the area around
the front wheels. The traction control
system activates when the system
senses that the wheels are spinning.
Turn off any traction or stability
system. With the wheels straight
ahead, shift back and forth between
R (Reverse) and a forward gear,
or with a manual transmission,
between 1 (First) or 2 (Second) and
R (Reverse), spinning the wheels
as little as possible. To prevent
transmission wear, wait until
the wheels stop spinning before
shifting gears. Release the
accelerator pedal while shifting, and
press lightly on the accelerator
pedal when the transmission is in
gear. Slowly spinning the wheels in
the forward and reverse directions
causes a rocking motion that
could free the vehicle. If that does
not get the vehicle out after a
few tries, it might need to be towed
out. The recovery loops can beused. If the vehicle does need to be
towed out, seeTowing Your
Vehicle on page 4-40.
Recovery Loops
{CAUTION
These loops, when used, are
under a lot of force. Keep people
away from the vicinity of the loops
and any chains or cables during
use. Always pull the vehicle
straight out. Never pull on the
loops at a sideways angle. The
loops could break off and you or
others could be injured from the
chain or cable snapping back.
Notice:Never use the recovery
loops to tow the vehicle. Your
vehicle could be damaged and it
would not be covered by
warranty.The vehicle has two recovery loops
at the front of the vehicle and
one at the rear of the vehicle.
Use them if the vehicle is stuck
off-road and needs to be pulled to
some place where the driver
can continue driving.

Service
For service and parts needs, visit
your dealer/retailer. You will receive
genuine GM parts and GM-trained
and supported service people.
Genuine GM parts have one
of these marks:
Accessories and
Modications
When non-dealer/non-retailer
accessories are added to the
vehicle, they can affect vehicle
performance and safety, including
such things as airbags, braking,
stability, ride and handling,
emissions systems, aerodynamics,
durability, and electronic systems
like antilock brakes, traction control,
and stability control. Some of
these accessories could even cause
malfunction or damage not
covered by the vehicle warranty.
Damage to vehicle components
resulting from the installation or use
of non-GM certied parts, including
control module modications,
are not covered under the terms of
the vehicle warranty and may
affect remaining warranty coverage
for affected parts.
Service and Appearance Care 5-3

GM’s exclusive TPC Spec
system considers over a dozen
critical specications that
impact the overall performance
of your vehicle, including brake
system performance, ride
and handling, traction control,
and tire pressure monitoring
performance. GM’s TPC
Spec number is molded onto
the tire’s sidewall near the
tire size. If the tires have an
all-season tread design, the TPC
spec number will be followed
by a MS, for mud and snow.
SeeTire Sidewall Labeling
on page 5-45for additional
information.
GM recommends replacing tires
in sets of four. This is because
uniform tread depth on all
tires will help keep your vehicle
performing most like it did
when the tires were new.Replacing less than a full set of
tires can affect the braking and
handling performance of your
vehicle. SeeTire Inspection
and Rotation on page 5-57
for information on proper tire
rotation.
{CAUTION
Mixing tires could cause you
to lose control while driving.
If you mix tires of different
sizes, brands, or types
(radial and bias-belted tires)
the vehicle may not handle
properly, and you could have
a crash. Using tires of different
sizes, brands, or types may
also cause damage to your
vehicle. Be sure to use the
correct size, brand, and type
of tires on your vehicle’s
wheels.
{CAUTION
If you use bias-ply tires on the
vehicle, the wheel rim anges
could develop cracks after
many miles of driving. A tire
and/or wheel could fail
suddenly, causing a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If you must replace your vehicle’s
tires with those that do not have a
TPC Spec number, make sure
they are the same size, load
range, speed rating, and
construction type (radial and
bias-belted tires) as your
vehicle’s original tires.
5-60 Service and Appearance Care

Vehicles equipped with a tire
pressure monitoring system may
give an inaccurate low-pressure
warning if non-TPC spec rated
tires are installed on your
vehicle. Non-TPC Spec rated
tires may give a low-pressure
warning that is higher or lower
than the proper warning level
you would get with TPC
Spec rated tires. SeeTire
Pressure Monitor System on
page 5-52.
Your vehicle’s original equipment
tires are listed on the Tire and
Loading Information Label.
SeeLoading the Vehicle
on page 4-35, for more
information about the Tire and
Loading Information Label
and its location on your vehicle.Different Size Tires and
Wheels
If you add wheels or tires that are a
different size than your original
equipment wheels and tires,
this could affect the way your vehicle
performs, including its braking,
ride and handling characteristics,
stability, and resistance to rollover.
Additionally, if your vehicle has
electronic systems such as anti-lock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.
{CAUTION
If you add different sized
wheels, your vehicle may not
provide an acceptable level of
performance and safety if tires not
recommended for those wheels
are selected. You may increase
the chance that you will crash and
suffer serious injury. Only use GM
specic wheel and tire systems
developed for your vehicle, and
have them properly installed by a
GM certied technician.

Uniform Tire Quality
Grading
Quality grades can be found
where applicable on the
tire sidewall between tread
shoulder and maximum section
width. For example:
Treadwear 200 Traction AA
Temperature A
The following information relates
to the system developed by
the United States National
Highway Traffic Safety
Administration (NHTSA), which
grades tires by treadwear,
traction, and temperature
performance. This applies
only to vehicles sold in the
United States. The grades are
molded on the sidewalls of
most passenger car tires.The Uniform Tire Quality
Grading (UTQG) system
does not apply to deep tread,
winter-type snow tires,
space-saver, or temporary use
spare tires, tires with nominal rim
diameters of 10 to 12 inches
(25 to 30 cm), or to some
limited-production tires.
While the tires available on
General Motors passenger cars
and light trucks may vary
with respect to these grades,
they must also conform to
federal safety requirements and
additional General Motors
Tire Performance Criteria (TPC)
standards.
Treadwear
The treadwear grade is a
comparative rating based on
the wear rate of the tire
when tested under controlled
conditions on a specied
government test course.For example, a tire graded
150 would wear one and a half
(1.5) times as well on the
government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions
of their use, however, and may
depart signicantly from the
norm due to variations in
driving habits, service practices,
and differences in road
characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest
to lowest, are AA, A, B, and C.
Those grades represent the
tire’s ability to stop on wet
pavement as measured under
controlled conditions on
specied government test
surfaces of asphalt and
concrete. A tire marked C may
have poor traction performance.
5-62 Service and Appearance Care

{WARNING
The traction grade assigned
to this tire is based on
straight-ahead braking traction
tests, and does not include
acceleration, cornering,
hydroplaning, or peak traction
characteristics.
Temperature – A, B, C
The temperature grades are
A (the highest), B, and C,
representing the tire’s resistance
to the generation of heat and
its ability to dissipate heat
when tested under controlled
conditions on a specied indoor
laboratory test wheel. Sustained
high temperature can cause
the material of the tire to
degenerate and reduce tire life,
and excessive temperature
can lead to sudden tire failure.The grade C corresponds to a
level of performance which
all passenger car tires must
meet under the Federal
Motor Vehicle Safety Standard
No. 109. Grades B and A
represent higher levels of
performance on the laboratory
test wheel than the minimum
required by law.
{WARNING
The temperature grade for this
tire is established for a tire
that is properly inated and
not overloaded. Excessive
speed, underination, or
excessive loading, either
separately or in combination,
can cause heat buildup and
possible tire failure.
Wheel Alignment and
Tire Balance
The tires and wheels on your
vehicle were aligned and balanced
carefully at the factory to give
you the longest tire life and best
overall performance. Adjustments to
wheel alignment and tire balancing
will not be necessary on a regular
basis. However, if you notice
unusual tire wear or your vehicle
pulling to one side or the other,
the alignment might need to
be checked. If you notice your
vehicle vibrating when driving on a
smooth road, the tires and wheels
might need to be rebalanced.
See your dealer/retailer for
proper diagnosis.
Service and Appearance Care 5-63

Tire Chains
{CAUTION
If your vehicle has LT285/75R16
or P265/65R18 size tires, do not
use tire chains. They can damage
your vehicle because there is not
enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle parts.
The area damaged by the tire
chains could cause you to lose
control of your vehicle and you or
others may be injured in a crash.
(Continued)
CAUTION (Continued)
Use another type of traction
device only if its manufacturer
recommends it for use on your
vehicle and tire size combination
and road conditions. Follow that
manufacturer’s instructions.
To help avoid damage to your
vehicle, drive slowly, readjust,
or remove the device if it is
contacting your vehicle, and do
not spin your vehicle’s wheels.
If you do nd traction devices
that will t, install them on the
rear tires.Notice:If your vehicle has a
tire size other than LT285/75R16
or P265/65R18 use tire chains
only where legal and only when
you must. Use chains that are
the proper size for your tires.
Install them on the tires of
the rear axle. Do not use chains
on the tires of the front axle.
Tighten them as tightly as
possible with the ends securely
fastened. Drive slowly and
follow the chain manufacturer’s
instructions. If you can hear
the chains contacting your
vehicle, stop and retighten them.
If the contact continues, slow
down until it stops. Driving
too fast or spinning the wheels
with chains on will damage
your vehicle.
