Buick 2009 Enclave - Manual (Page 339)

Changing a Flat Tire
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 3-5.
{ 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).

CAUTION (Continued)
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.
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).
