Changing A Flat Tire - GMC 2009 Yukon XL Owner's Manual

Changing a Flat Tire

If your vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on the hazard
warning flashers. See Hazard Warning Flashers
on page 3-6.
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 firmly.
2. Put the shift lever in P (Park).
3. If you have a four-wheel-drive vehicle,
be sure the transfer case is in a drive
gear — not in N (Neutral).
4. Turn off the engine and do not restart while
the vehicle is raised.

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.
When the vehicle has a flat tire (B), use the following
example as a guide to assist you in the placement
of wheel blocks (A).
