9-32 Driving and Operating
Similar appearing vehicles may
have different GVWRs and
capacity weights. Please note
the vehicle's Certification/Tire
label or consult your dealer for
additional details.
{WARNING
Do not load the 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 the vehicle
can break, and it can change
the way the vehicle handles.
These could cause you to
lose control and crash. Also,
overloading can shorten the
life of the vehicle. Using heavier suspension
components to get added
durability might not change
the weight ratings. Ask your
dealer to help you load the
vehicle the right way.Notice :Overloading the
vehicle may cause damage.
Repairs would not be covered
by the vehicle warranty. Do
not overload the vehicle.
If you put things inside your
vehicle –like suitcases,
tools, packages, or anything
else –they will 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.
{WARNING
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.

10-64 Vehicle Care
Tire Chains
{WARNING
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.
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.(Continued)
WARNING (Continued)
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 find traction devices that
will fit, 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.
If a Tire Goes Flat
It is unusual for a tire to blowout
while you are driving, especially if
you maintain your vehicle's tires
properly. If air goes out of a tire, it is
much more likely to leak out slowly.
But if you should ever have a
blowout, here are a few tips about
what to expect and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop well out of the
traffic lane.

Managing the Vehicle Damage
Repair Process
In the event that your vehicle
requires damage repairs, HUMMER
recommends that you take an active
role in its repair. If you have a
pre-determined repair facility of
choice, take your vehicle there,
or have it towed there. Specify
to the facility that any required
replacement collision parts be
original equipment parts, either
new Genuine parts or recycled
original parts. Remember, recycled
parts will not be covered by your
HUMMER vehicle warranty.
Insurance pays the bill for
the repair, but you must live
with the repair. Depending on
your policy limits, your insurance
company may initially value the
repair using aftermarket parts.Discuss this with your repair
professional, and insist on Genuine
parts. Remember if your vehicle is
leased you may be obligated to
have the vehicle repaired with
Genuine parts, even if your
insurance coverage does not pay
the full cost.
If another party's insurance
company is paying for the repairs,
you are not obligated to accept a
repair valuation based on that
insurance company's collision
policy repair limits, as you have no
contractual limits with that company.
In such cases, you can have control
of the repair and parts choices as
long as cost stays within reasonable
limits.
