2008 CADILLAC CTS Owners Manual

The sealant can temporarily seal a puncture up to 6 mm
in the tread area of the tire ire. The sealant cannot
seal sidewall damage, large punctures, or a tire that
has unseated from the wheel. SeeRoadside Service
on page 7-7.
Using the Tire Sealant and Compressor
Kit to Temporarily Seal and Inate a
Punctured Tire
Follow these directions closely for correct sealant
usage.
1. Do a safety check before proceeding. SeeIf a Tire
Goes Flat on page 5-82.
2. Inspect the damaged tire.
The sealant cannot seal sidewall damage, large
punctures, or a tire that has unseated from
the wheel. SeeRoadside Service on page 7-7.3. Place the tire sealant and compressor kit on the
ground and unwrap the sealant/air hose (G) from
the side of the compressor.
4. Remove the tire valve stem cap from the at tire by
turning it counterclockwise.
5. Attach the sealant/air hose (G) onto the tire valve
stem. Turn it clockwise until it is tight.
Make sure the sealant and compressor kit On/Off
switch (D) is in the O (off) position.
6. Remove the air compressor accessory plug (C)
from the unit.
5-95

7. Plug the air compressor accessory plug (C) into an
accessory power outlet in the vehicle. SeeAccessory
Power Outlet(s) on page 3-22for more information.
Do not slam door or close window on the
compressor accessory plug cord.
{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 2-48.
8. Start the vehicle. SeeStarting the Engine on
page 2-35for more information. The vehicle must
be running while using the air compressor.
{CAUTION:
Overination could cause the tire to rupture,
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).
9. Push the On/Off switch to the I (on) position.
The tire sealant and compressor kit will inject
sealant and air into the tire.
The pressure gage (E) 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 only.
5-96

10. Inate the tire to the recommended ination
pressure using the air pressure gage (E) on the top
of the unit. The recommended ination pressure
can be found on the Tire and Loading Information
label. SeeInflation - Tire Pressure on page 5-66.
The pressure gage reading is slightly high while the
compressor is on. Turn the compressor off to get
an accurate pressure reading. The compressor may
be turned on and off until the correct pressure is
reached.
Notice:If the recommended pressure cannot be
reached after approximately 25 minutes, the vehicle
should not be driven farther. The tire is too severely
damaged and the tire sealant and compressor kit
cannot inate the tire. Remove the air compressor
plug from the accessory power outlet and unscrew
the inating hose from the tire valve. SeeRoadside
Service on page 7-7.
11. Turn the compressor off by pushing the On/Off
switch (D) to the O (off) position.
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 12 through 19 must be done immediately
after Step 11.
Be careful while handling the tire sealant and
compressor kit as they could be hot after usage.12. Unplug the air compressor accessory plug (C) from
the accessory power outlet in the vehicle.
13. Disconnect the sealant/air hose (G) from the tire
valve stem by turning it counterclockwise and
replace the tire valve stem cap.
14. Wrap the sealant/air hose (G) around the air
compressor channel to stow it in its original location.
15. Stow the air compressor accessory plug (C) 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.
16. If the at tire was able
to be inated to the
recommended ination
pressure, remove the
maximum speed label
from the sealant
canister (B).
5-97

17. 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 its original location.
18. Return the equipment to its original storage location
in your vehicle.
19. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant evenly in the tire.20. 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 an Underinated Tire (Not Punctured)”
next in this section.
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 7-7for more information.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, inate the tire back up to the
recommended ination pressure.
21. Wipe off any sealant from the wheel, tire, and
vehicle.
22. Dispose of the sealant canister (B) and sealant/air
hose (G) assembly 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.
23. After temporarily sealing a tire with the tire sealant
and compressor kit, take your vehicle to your
dealer/retailer to have the tire repaired or replaced.
5-98

Using the Air Compressor without

Removal and Installation of the Sealant
Canister
To remove the sealant canister:
1. Unlock the air only hose from the sealant canister
by pulling the lever up.
2. Pull the air only hose from the sealant canister.
3. Unwrap the sealant/air 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.
5-101

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 only hose onto the sealant canister inlet
and push the lever down.
Changing a Flat Tire
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.
{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.
