2008 CADILLAC CTS spare tire

Tire Sealant and Compressor Kit
(Without Sealant Selector Switch)
Your vehicle has a tire sealant and compressor kit that
is capable of temporarily sealing a small puncture up to
6 mm in the tread. There is no jack or spare tire. The kit
inates the tire with liquid sealant and air. The tire sealant
and compressor kit can also be used to inate an
underinated tire. After the tire is inated to the
recommended ination pressure, seeInflation - Tire
Pressure on page 5-66, the vehicle must be driven for
ve miles to distribute the sealant in the tire and seal the
puncture. After driving ve miles the tire pressure must be
rechecked and adjusted as needed. See “Using the Tire
Sealant and Compressor Kit to Temporarily Seal and
Inate a Punctured Tire” later in this section. Be sure to
read and follow all of the tire sealant and compressor kit
instructions. The kit includes:
After temporarily repairing the tire sealant and
compressor kit, it is recommended to take your vehicle to
an authorized dealer/retailer as soon as possible. If the
sealant is removed within 100 miles (161 kilometers)
of driving, then it is easier to clean from the tire and
you are less likely to require a replacement tire.A. Air Compressor

come off and cause an accident. When you
change a wheel, remove any rust or dirt from
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. SeeChanging a Flat Tire on

Compact Spare Tire
If your vehicle is equipped with a compact spare tire it
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, 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), so you can nish your trip and
have the full-size tire repaired or replaced at your
convenience. Of course, it is best to replace the spare
with a full-size tire as soon as possible. The spare tire
will last longer and be in good shape in case it is needed
again.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.
Notice:Tire chains will not t your compact spare.
Using them can damage your vehicle and can
damage the chains too. Do not use tire chains on
your compact spare.
