Changing a Flat Tire
If you have an STS-V model, there is no spare tire
and no tire changing equipment. Your vehicle is
equipped with run-at tires. SeeRun-Flat
Tires (STS-V) on page 429for more information. If
you have an STS model, your vehicle may be
equipped with a tire inator kit. SeeTire Inator Kit
on page 452for more information. If your vehicle
is not equipped with a tire inator kit, follow
the directions for changing a at tire in this section.
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. See
Hazard Warning Flashers on page 180for 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.
