2004 GMC CANYON Owner's Manual

If a Tire Goes Flat
It’s unusual for a tire to “blowout” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s 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 at tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel rmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use
in a skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a at tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a at tire.
If a tire goes at, the next part shows how to use your
jacking equipment to change a at tire safely.

Changing a Flat Tire
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your
hazard warning ashers. SeeHazard Warning Flashers
on page 3-4for more information.
{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. Find a level place to
change your tire. To help prevent the vehicle
from moving:
1.
Set the parking brake rmly.
2. Put an automatic transmission shift lever
in PARK (P), or shift a manual transmission
to FIRST (1) or REVERSE (R).
3. Turn off the engine and do not restart while
the vehicle is raised.
4. Do not allow passengers to remain in the
vehicle.
CAUTION: (Continued)
CAUTION: (Continued)
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.
The following steps will tell you how to use the jack and
change a tire.

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.

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.

1. Assemble the wheel wrench (D) and the jack
handle extensions (A) as shown.

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.
