Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your vehicle’s hazard warning flashers.
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 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.
When your vehicle has a flat 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.
