2008 CADILLAC STS Owners Manual

The pressure gage will initially show a high pressure
while the compressor pushes the sealant into the
tire. Once the sealant is completely dispersed
into the tire, the pressure will quickly drop and start
to rise again as the tire inates with air.
8. Inate the tire to the recommended ination
pressure, found on the Tire and Loading Information
label located on the vehicle’s center pillar (B-pillar)
below the vehicle’s door latch, using the air
pressure gage on the top of the unit.
The pressure gage reads high while the compressor
is running. Turn the compressor off to get an
accurate pressure reading.
Notice:If the recommended pressure cannot be
reached after 15 minutes, the vehicle should not be
driven farther. Damage to the tire is severe and
the sealant will not be effective. Remove the
air compressor plug from the accessory power
outlet and unscrew the inating hose from the tire
valve. SeeRoadside Service on page 7-6.
9. Push the sealant and compressor kit switch to
the O (off) position.10. The tire is not sealed and will continue to leak air
until the vehicle is driven and the sealant is
distributed in the tire.
Steps 11 through 18 must be done right after
Step 10.
11. Unplug the air compressor accessory plug from the
accessory power outlet in the vehicle.
12. Disconnect the sealant lling hose from the tire
valve stem, by turning it counterclockwise, and
replace the tire valve stem cap.
Be careful when handling the tire inator
components as they may be hot after usage.
13. Wrap the sealant lling hose around the air
compressor channel to stow it in its original location.
14. Stow the air compressor accessory plug back in the
air compressor. To do this, wrap the air compressor
accessory plug, snap in the plug, and then push
in the bottom and then the top of the wrapped
air compressor accessory plug.
5-91

15. If the at tire was able
to inate to the
recommended ination
pressure, remove
the maximum speed
label from the sealant
canister.
Place it in a highly visible location such as the
inside of the upper left corner of the windshield or
to the face of the radio/clock.
The maximum speed label reminds you to drive
cautiously and not to exceed 55 mph (90 km/h) until
you have the damaged tire inspected and repaired.{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 the proper place.
16. Return the equipment to the proper storage location
in the trunk of your vehicle. You may need to
loosen the retention strap to wrap it around the
sealant and compressor kit and foam container.
To do this, pull apart the strap and loosen the strap
at the quick release buckle. Then snap the buckle
together, pull the strap tight, and secure the
loose end of the strap by mating the ends.
17. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant evenly in the tire. Stop at a
safe location and check the tire pressure, refer
to Steps 1 through 8 under “Using the Air
Compressor without Sealant” next in this section.
5-92

18. If the tire pressure has fallen more then 10 psi
(68 kPa), below the recommended ination
pressure, stop driving the vehicle. The tire is too
severely damaged and the tire sealant and
compressor kit cannot seal the tire. SeeRoadside
Service on page 7-6for more information.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, you can inate the tire back up to
the recommended ination pressure.
19. Wipe off any sealant from the wheel, tire, and
vehicle with a rag.
20. Dispose of the sealant canister at a local
dealer/retailer or in accordance with your local state
codes and practices.
After using the sealant canister, replace it with a
new canister from your dealer/retailer.
21. After temporarily sealing a tire with the tire sealant
and compressor kit, take your vehicle to your
dealer/retailer to have the tire inspected and
repaired.Using the Air Compressor without
Sealant
To use the air compressor to inate a tire with air only
and not sealant:
1. Remove the air compressor inating hose connector
from the bottom of the air compressor.
2. Unlock the air compressor hose from the sealant
canister by pulling up on the lever.
5-93

3. Pull the air compressor inator hose from the
sealant canister.
4. Push the air compressor inator hose onto the
tire valve stem and push the lever down to
secure in place.
5. Plug the air compressor accessory plug into an
accessory power outlet in the vehicle. SeeAccessory
Power Outlet(s) on page 3-46for more information.
{CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause
deadly carbon monoxide (CO). SeeEngine
Exhaust on page 2-38.
6. Start the vehicle. SeeStarting the Engine on
page 2-29for more information. The vehicle must be
running while using the air compressor.
{CAUTION:
Inating something too much can make it
explode, and you or others could be injured.
Be sure to read the inator instructions, and
inate the tire to its recommended pressure.
Do not exceed 36 psi (248 kPa).
7. Move the sealant and compressor kit switch to
the I (on) position.
8. Inate the tire up to the recommended ination
pressure using the air pressure gage on the top
of the unit.
The pressure gage read high while the compressor
is running. Turn the compressor off to get an
accurate reading.
5-94

9. Turn off the air compressor by moving the switch to
the O (off) position.
{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 the proper place.
10. Disconnect the compressor inator hose and wrap
the hose in the bottom of the sealant and
compressor kit.
11. Place the equipment in the original location in the
trunk of your vehicle.
Removal and Installation of the Sealant
Canister
To remove the sealant canister:
1. Unlock the air compressor inator hose from the
sealant canister by pulling the lever up.
2. Disconnect the air compressor inator hose from
the sealant canister.
5-95

3. Unwrap the sealant lling hose from the
compressor.
4. Turn the sealant canister so the inator lling hose
is aligned with the slot in the compressor.
5. Lift the sealant canister from the compressor and
replace with a new sealant canister. See your
dealer/retailer for more information.To install a new sealant canister:
1. Align the sealant lling hose with the slot in the air
compressor.
2. Push the sealant canister down and turn it
clockwise.
3. Wrap the sealant lling hose around the air
compressor channel to stow it in its original location.
4. Push the air compressor inator hose onto the
sealant canister inlet and push the lever down.
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.
5-96

{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.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.

To gain access to the compact spare tire and jacking
equipment:
1. Open the trunk. SeeTrunk on page 2-16for 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.4. Remove the compact spare tire. SeeCompact
