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 5-65for more information. If you have an STS
model, your vehicle may be equipped with a tire inator
kit. SeeTire Sealant and Compressor Kit on page 5-87
for 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. SeeHazard Warning Flashers
on page 3-6for more information.

Compact Spare Tire
Although the compact spare tire was fully inated when
the vehicle was new, it can lose air after a time.
Check the ination pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on the vehicle, you
should stop as soon as possible and make sure the spare
tire is correctly inated. The compact spare is made to
perform well at speeds up to 65 mph (105 km/h) for
distances up to 3,000 miles (5 000 km). The tire ination
monitor system must be calibrated after installing or
removing the compact spare. SeeTire Pressure Monitor
System on page 5-68. The system may not work correctly
when the compact spare is installed on the vehicle.It’s best to replace the spare with a full-size tire as soon
as soon as possible. The spare will last longer and be in
good shape if needed it again.
If your vehicle has All Wheel Drive (AWD) it could also
have an StabiliTrak
®3. SeeStabiliTrak®System on
page 4-8for more information. If the compact spare tire
is installed on a vehicle with the StabiliTrak
®3
System, the vehicle operates in the Stability Secure
Mode. The STABILITY SECURE MODE message
displays on the Driver Information Center (DIC). See
DIC Warnings and Messages on page 3-80for
more information.
Notice:When the compact spare is installed, do
not take your vehicle through an automatic car wash
with guide rails. The compact spare can get
caught on the rails. That can damage the tire and
wheel, and maybe other parts of your vehicle.
Do not use the compact spare on other vehicles.
And do not mix the compact spare tire or wheel with
other wheels or tires. They will not t. Keep the
spare tire and its wheel together.
