2009 CADILLAC STS wheel

{CAUTION:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that has
no fresh air ventilation. For more information, see
Engine Exhaust on page 2-36.
{CAUTION:
Over-inating a tire could cause the tire to rupture
and you or others could be injured. Be sure to
read and follow the tire sealant and compressor kit
instructions and inate the tire to its recommended
pressure. Do not exceed the recommended
pressure.
{CAUTION:
Storing the tire sealant and compressor kit or
other equipment in the passenger compartment of
the vehicle could cause injury. In a sudden stop or
collision, loose equipment could strike someone.
Store the tire sealant and compressor kit in its
original location.
If this vehicle has a tire sealant and compressor kit,
there may not be a spare tire, tire changing equipment,
and on some vehicles there may not be a place to
store a tire.
The tire sealant and compressor can be used to
temporarily seal punctures up to
14inch (6 mm) in the
tread area of the tire. It can also be used to inate
an under inated tire.
If the tire has been separated from the wheel, has
damaged sidewalls, or has a large puncture, the tire is
too severely damaged for the tire sealant and
compressor kit to be effective. SeeRoadside Service on
page 7-7.
Read and follow all of the tire sealant and compressor
kit instructions.

16. If the at tire was
able to inate to the
recommended ination
pressure, remove
the maximum speed
label from the sealant
canister (E) and
place it in a highly
visible location.
The label is a reminder not to exceed 55 mph
(90 km/h) until the damaged tire is repaired
or replaced.
17. Return the equipment to its original storage location
in the vehicle.
18. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant in the tire.
19. Stop at a safe location and check the tire pressure.
Refer to Steps 1 through 11 under “Using the Tire
Sealant and Compressor Kit without Sealant to
Inate a Tire (Not Punctured).”If the tire pressure has fallen more than 10 psi
(68 kPa) below the recommended ination pressure,
stop driving the vehicle. The tire is too severely
damaged and the tire sealant cannot seal the tire.
SeeRoadside Service on page 7-7.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, inate the tire to the recommended
ination pressure.
20. Wipe off any sealant from the wheel, tire, and
vehicle.
21. Dispose of the used sealant canister (E) and
sealant/air hose (F) assembly at a local
dealer/retailer or in accordance with local state
codes and practices.
22. Replace it with a new canister available from your
dealer/retailer.
23. After temporarily sealing a tire using the tire sealant
and compressor kit, take the vehicle to an authorized
dealer/retailer within a 100 miles (161 km) of driving
to have the tire repaired or replaced.

Tire Sealant and Compressor Kit
Storage
The tire sealant and compressor kit is located in
the trunk.
1. Open the trunk. SeeTrunk on page 2-15.
2. Remove the retainer that holds the tire sealant and
compressor kit in place.
3. Remove the tire sealant and compressor kit from
the foam container.
To store the tire sealant and compressor kit, reverse
the steps.
Changing a Flat Tire
If you have an STS-V model, there is no spare tire and
no tire changing equipment. The vehicle is equipped
with run-at tires. SeeRun-Flat Tires (STS-V) on
page 5-62for more information. If you have an STS
model, the vehicle may be equipped with a tire inator
kit. SeeTire Sealant and Compressor Kit on page 5-87
for more information. If the 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 the hazard
warning ashers. SeeHazard Warning Flashers
on page 3-6.
5-104

{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 P (Park).
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 the vehicle has a at tire (B), use the following
example as a guide to assist you in the placement
of wheel blocks (A).
A. Wheel Block
B. Flat Tire
The following information explains 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 access to the compact spare tire and jacking
equipment:
1. Open the trunk. SeeTrunk on page 2-15for more
information.
2. Remove the compact spare tire cover.
3. Pull the stow rod (A) to remove it.
4. Turn the nut (B) holding the jack package container
counterclockwise and remove it. Then remove the
jack and wheel wrench.
5. Remove the compact spare tire. SeeCompact
Spare Tire on page 5-114for more information
about the compact spare tire.
5-106

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. Do a safety check before proceeding. SeeChanging
a Flat Tire on page 5-104for more information.
2. Loosen all of 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.
5-107

3. Find the vehicle’s jacking location using the
diagram above and corresponding V–shaped
notches located in the plastic molding on the
vehicle’s frame. The notches in the plastic molding
are marked with a triangle shape.
4. 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.
5-108

{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without the
appropriate safety equipment and training. If a jack
is provided with the vehicle, it 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. If a jack is provided with
the vehicle, only use it 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 position the jack so that when the
jack head is raised, it will t rmly in the notch
located inboard from the rocker molding.
5. Turn the wheel wrench counterclockwise to lower
the jack lift head until the jack ts under the vehicle.6. Raise the jack by turning the wheel wrench
clockwise until the slots in the jack head t into
the metal ange located behind the triangle on
the plastic molding as shown.
7. Put the compact spare tire near you.
