2009 CADILLAC STS spare tire

{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.

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
