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
hazard warning flashers. See Hazard Warning Flashers
on page 3-6 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 firmly.
2. Put the shift lever in PARK (P).
3. If you have a four-wheel-drive vehicle, be
sure the transfer case is in a drive
gear— not in NEUTRAL.

while the vehicle is raised.
5. Do not allow passengers to remain in
the vehicle.
