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.
464

When your vehicle has a at 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.Removing the Spare Tire and Tools
The equipment you will need is located in the
trunk. To gain access to the compact spare tire
and jacking equipment, do the following:
1. Open the trunk. SeeTrunk on page 101for
more information.
2. Remove the compact spare tire cover.
3. Turn the nut holding the jack package
container counterclockwise and remove
it. Then remove the jack and wheel wrench.
465

4. Remove the compact spare tire. SeeCompact
Spare Tire on page 475for more information
about the compact spare tire.
The tools you will be using include the jack (A)
and the wheel wrench (B).Removing the Flat Tire and
Installing the Spare Tire
1. Loosen the wheel nuts, but do not remove
them yet, using the wheel wrench. Turn the
handle about 180 degrees, then ip the handle
back to the starting position. This avoids
taking the wrench off the lug nut for each turn.
466

2. Find the vehicle’s jacking location using the
diagram above and corresponding hoisting
notches located in the plastic molding on the
vehicle’s frame. The notches in the plastic
molding are marked with a triangle shape to
help you nd them.
3. Attach the wheel wrench to the jack.
{CAUTION:
Getting under a vehicle when it is jacked
up is dangerous. If the vehicle slips off
the jack you could be badly injured or
killed. Never get under a vehicle when it is
supported only by a jack.
{CAUTION:
Raising your vehicle with the jack
improperly positioned can damage the
vehicle and even make the vehicle fall. To
help avoid personal injury and vehicle
damage, be sure to t the jack lift head into
the proper location before raising the
vehicle.
467

{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
at tire. If it is used for anything else, you
or others could be badly injured or killed
if the vehicle slips off the jack. Use the
jack provided with your vehicle only for
changing a at tire.Notice:If you position the jack under the
rocker molding and attempt to raise the
vehicle, you could break the molding and/or
cause other damage to your vehicle. Always

clockwise until the slots in the jack head t
into the metal ange located behind the
triangle on the plastic molding as shown.
6. Put the compact spare tire near you.7. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off
the ground for the compact spare tire to
t under the vehicle.
469

8. Remove all the
wheel nuts and take
off the at tire.
{CAUTION:
Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after time. The
wheel could come off and cause an
accident. When you change a wheel,
CAUTION: (Continued)
CAUTION: (Continued)
remove any rust or dirt from the places
where the wheel attaches to the vehicle. In
an emergency, you can use a cloth or a
paper towel to do this; but be sure to use
a scraper or wire brush later, if needed, to
get all the rust or dirt off.
{CAUTION:
Never use oil or grease on studs or nuts.
If you do, the nuts might come loose.
Your wheel could fall off, causing a
serious accident.
