2007 GMC YUKON Owner's Manual

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 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 would 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 the
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 vehicle’s hazard warning ashers.
SeeHazard Warning Flashers on page 192
for 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 the shift lever in PARK (P).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain
in the vehicle.
To be even more certain the vehicle will
not move, you should put 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.
506

When your vehicle has a at tire, use the following
example as a guide to assist you in the placement
of wheel blocks.
The following information will tell you next how to
use the jack and change a tire.Removing the Spare Tire and Tools

tire is stored under the storage tray, which
is located on the driver’s side trim panel (over
the rear wheelhouse).
1. Remove the tray to access the tools by
pulling up on the nger depression under
the jack symbol.

Be sure the hoist end (J) of the extension (D)
connects to the hoist shaft (B). The ribbed

the spare tire.
6. Turn the wheel wrench (E) counterclockwise
to lower the spare tire (H) to the ground.
Continue to turn the wheel wrench until the
spare tire can be pulled out from under

If the spare tire does not lower to the ground,
the secondary latch is engaged causing
the tire not to lower. SeeSecondary Latch
System on page 518for more information.7. Use the wheel
wrench hook that
allows you to
pull the hoist cable
towards you, to
assist in reaching
the spare tire.
8. Tilt the tire
retainer (G) at the
end of the cable

pulled up through
the wheel opening.
9. Put the spare tire near the at tire.
