2004 GMC CANYON spare wheel

Before You Go Off-Roading
There are some things to do before you go out.
For example, be sure to have all necessary maintenance
and service work done. Check to make sure all
underbody shields (if so equipped) are properly
attached. Be sure you read all the information about
your four-wheel-drive vehicle in this manual. Is
there enough fuel? Is the spare tire fully inated?
Are the uid levels up where they should be? What are
the local laws that apply to off-roading where you
will be driving? If you do not know, you should check
with law enforcement people in the area. Will you be
on someone’s private land? If so, be sure to get
the necessary permission.
Loading Your Vehicle for Off-Road
Driving
There are some important things to remember about
how to load your vehicle.
The heaviest things should be on the load oor and
forward of your rear axle. Put heavier items as far
forward as you can.
Be sure the load is secured properly, so driving on
the off-road terrain does not toss things around.
{CAUTION:
Cargo on the load oor piled higher than
the seatbacks can be thrown forward
during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.
Unsecured cargo on the load oor can be
tossed about when driving over rough
terrain. You or your passengers can be
struck by ying objects. Secure the cargo
properly.
Heavy loads on the roof raise the vehicle’s
center of gravity, making it more likely to
roll over. You can be seriously or fatally
injured if the vehicle rolls over. Put heavy
loads inside the cargo area, not on the
roof. Keep cargo in the cargo area as far
forward and low as possible.
You will nd other important information in this manual.

When to Check
Check your tires once a month or more.
Also, check the tire pressure of the spare tire.
If you have a compact spare tire, it should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell if your tires are properly inated
simply by looking at them. Radial tires may look properly
inated even when they’re underinated. Check the tire’s
ination pressure when the tires are cold. cold means
your vehicle has been sitting for at least three hours or
driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to get a
pressure measurement. If the cold tire ination pressure
matches the recommended pressure on the tire and
loading information label, no further adjustment is
necessary. If the pressure is low, add air until you reach
the recommended amount.
If you overll the tire, release air by pushing on the
metal stem in the center of the tire valve. Recheck the
tire pressure with the tire gage.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and moisture.
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. SeeWhen It Is Time
for New Tires on page 5-67andWheel Replacement
on page 5-70for more information.
Make sure the spare tire is stored securely. Push, pull,
and then try to rotate or turn the tire. If it moves, use the
wheel wrench to tighten the cable. SeeChanging a Flat
Tire on page 5-74.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst rotation
is the most important, seeScheduled Maintenance on
page 6-4.
5-65

When rotating your tires, always use one of the correct
rotation patterns shown here.
If your vehicle has a compact spare tire or a spare tire
that does not match your vehicle’s road tires and
wheels, in size and type, do not include the spare in the
tire rotation.After the tires have been rotated, adjust the front and
rear ination pressures as shown on the Tire and
Loading Information label. For the location of the tire
and loading information label seeLoading Your Vehicle
on page 4-52. Make certain that all wheel nuts are
properly tightened, see “Wheel Nut Torque” under
Capacities and Specications on page 5-108for the
proper wheel nut torque specication.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to,
to get all the rust or dirt off. See “Changing a
Flat Tire” in the Index.

Buying New Tires
To nd out what kind and size of tires you need, look at
the Certication/Tire label or the Tire and Loading
Information label. SeeLoading Your Vehicle on
page 4-52, for examples of these labels and where they
can be found on your vehicle.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specication (TPC Spec)
number on each tire’s sidewall. When you get new tires,
GM recommends that you get tires with that same
TPC Spec number. That way your vehicle will continue
to have tires that are designed to give proper
endurance, handling, speed rating, traction, ride and
other things during normal service on your vehicle.
If your tires have an all-season tread design, the TPC
number will be followed by an “MS” (for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type
(bias, bias-belted or radial) as your original tires.{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes
or types (radial and bias-belted tires), the
vehicle may not handle properly, and you
could have a crash. Using tires of different
sizes may also cause damage to your vehicle.
Be sure to use the same size and type tires on
all wheels. It’s all right to drive with your
compact spare (if you have one). It was
developed for use on your vehicle.
{CAUTION:
If you use bias-ply tires on your 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 your vehicle.

Removing the Spare Tire and ToolsThe tools you will need are under the passenger’s seat.
For crew cab models, the jack and wheel blocks are
under the driver’s side rear seat. 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.
1. The vehicle will
have a cover if it
is an extended or
regular cab.

Extended Cab

2. Move the seats forward and 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. The wheel blocks and the wheel block retainer can
be removed by turning the wing nut
counterclockwise.
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.
4. There is also a wing nut used to retain the storage
bag and tools located under the front passenger’s
seat. To remove it, turn the wing nut
counterclockwise.You will use the jack handle extensions and the wheel
wrench to remove the underbody-mounted spare tire.
A. Jack Handle
Extensions
B. Bottle JackC. Extension Tool
D. Wheel Wrench
E. Wheel Blocks
1. Assemble the wheel wrench (D) and the jack
handle extensions (A) as shown.
5-76

2. Insert the hoist end (chiseled end) of the extension
tool through the hole in the rear bumper and into
the funnel-shaped guide. The chiseled end of
the extension is used to lower the spare tire.
3. Turn the wheel wrench (D) counterclockwise to
lower the spare tire to the ground. Continue to
turn the wheel wrench until the spare tire can be
pulled out from under the vehicle.
If the spare tire does not lower to the ground, the
secondary latch is engaged causing the tire not to
lower. See “Secondary Latch System” later in this
section.4. When the tire has been
lowered, tilt the retainer
and slide it up the
cable so it can
be pulled up through
the wheel opening.
5. Put the spare tire near the at tire.
