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.
{CAUTION:
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.There is also important loading information for
off-road driving in this manual. See“Loading Your
Vehicle for Off-Road Driving”underOff-Road
Driving on page 260.
Remember not to exceed the Gross Axle Weight
rating (GAWR) of the front or rear axle.
Two-Tiered Loading
By positioning four 2” X 6” wooden planks across
the width of the pickup box, you can create an
upper load platform. The planks must be inserted
in the pickup box depressions. The length of
the planks must allow for at least a 3/4 inch (2 cm)
bearing surface on each end of the plank.
When using this upper load platform, be sure the
load is securely tied down to prevent it from
shifting. The load’s center of gravity should be
positioned in a zone over the rear axle.
Any load that extends beyond the vehicle’s
taillamp area must be properly marked according
to local laws and regulations.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the rear axle.

(D) Construction Code:A letter code is used
to indicate the type of ply construction in the tire.
The letter R means radial ply construction; the
letter D means diagonal or bias ply construction;
and the letter B means belted-bias ply
construction.
(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:These characters
represent the load range and speed rating of the
tire. The load index represents the load carry
capacity a tire is certi ed to carry. The load index
can range from 1 to 279. The speed rating is the
maximum speed a tire is certi ed to carry a load.
Speed ratings range from A to Z.
Tire Terminology and De nitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the tire.
Air pressure is expressed in pounds per square
inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic transmission,
power steering, power brakes, power windows,
power seats, and air conditioning.Aspect Ratio:The relationship of a tire’s height
to its width.
Belt:A rubber coated layer of cords that is located
between the plies and the tread. Cords may be
made from steel or other reinforcing materials.
Bead:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.
Cold Tire Pressure:The amount of air pressure
in a tire, measured in pounds per square inch (psi)
or kilopascals (kPa) before a tire has built up heat
from driving. SeeIn ation - Tire Pressure on
page 384.
Curb Weight:This means the weight of a motor
vehicle with standard and optional equipment
including the maximum capacity of fuel, oil, and
coolant, but without passengers and cargo.

For regular and
extended cab vehicles,
the jack and wheel
blocks are located
under the cover at the
center of the vehicle
behind the front seats.
To access the tools:
1. Move the seats
forward to access
the cover.2. Turn the wing nut on the cover
counterclockwise to remove it.
For crew cab models, reach under the rear
seat to access the jack and wheel blocks.
To reinstall the jack and wheel block assembly
in the mounting bracket, insert the tabs into
the jack base by pushing the blocks up into
the assembly. The outer hole in the jack base
aligns with the tab on the bracket. When
reinstalling, make sure the jack is secure, but
do not overtighten the jack in the bracket.
3. Remove the wheel blocks and the wheel
block retainer by turning the wing nut
counterclockwise.
4. Put the wheel blocks at the front and rear
of the tire farthest away from the one being
changed. That would be the tire on the
other side, at the opposite end of the vehicle.
5. Locate the wing nut used to retain the storage
bag and tools which is under the front
passenger’s seat. Remove it by turning the
wing nut counterclockwise.
You will use the jack handle extensions and the
wheel wrench to remove the underbody-mounted
spare tire.

{CAUTION:
Incorrect wheel nuts or improperly
tightened wheel nuts can cause the wheel
to come loose and even come off. This
could lead to an accident. Be sure to use
the correct wheel nuts. If you have to
replace them, be sure to get new GM
original equipment wheel nuts. Stop
somewhere as soon as you can and have
the nuts tightened with a torque wrench
to the proper torque speci cation. See
Capacities and Specifications on page 437
for wheel nut torque speci cation.
Notice:Improperly tightened wheel nuts can
lead to brake pulsation and rotor damage.
To avoid expensive brake repairs, evenly
tighten the wheel nuts in the proper sequence
and to the proper torque speci cation. See
Capacities and Specifications on page 437
for the wheel nut torque speci cation.11. Tighten the
wheel nuts  rmly
in a crisscross
sequence as
shown by turning
the wheel wrench
clockwise.
When you reinstall the regular wheel and tire,
you must also reinstall the center cap. Place
the cap on the wheel and tap it into place until
it seats  ush with the wheel. The cap only goes
on one way. Be sure to line up the tab on the
center cap with the indentation on the wheel.
For the Xtreme, tighten each nut cap by hand,
then tighten an additional one quarter of a turn
with the wheel wrench.
