B. Selector Switch(Sealant/Air or Air Only)
C. Pressure Relief Button
D. Pressure Gauge
E. Air Only Hose (Black)
F. Sealant/Air Hose (Clear)

Tire Sealant
Read and follow the safe handling
instructions on the label adhered to
the compressor.
Check the tire sealant expiration
date on the sealant canister.
The sealant canister should be
replaced before its expiration date.
Replacement sealant canisters
are available at your local dealer.
See “Removal and Installation of
the Sealant Canister” following.
There is only enough sealant to
seal one tire. After usage, the
sealant canister and sealant/air
hose assembly must be replaced.
See “Removal and Installation of
the Sealant Canister” following.
Using the Tire Sealant
and Compressor Kit to
Temporarily Seal and Inflate
a Punctured Tire
Follow the directions closely for
correct sealant usage.
When using the tire sealant
and compressor kit during cold
temperatures, warm the kit in a
heated environment for five minutes.
This will help to inflate the tire
faster.

If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. SeeHazard
Warning Flashers on page 6‑4.
See If a Tire Goes Flat on
page 10‑70 for other important
safety warnings.
Do not remove any objects that
have penetrated the tire.
1. Remove the tire sealant and compressor kit from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10‑79.
2. Unwrap the sealant/air hose (F) and the power plug (G).
3. Place the kit on the ground. Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it
counterclockwise. 5. Attach the sealant/air hose (F)
onto the tire valve stem. Turn it
clockwise until it is tight.
6. Plug the power plug (G) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets on page 5‑7.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.
If the vehicle only has a cigarette
lighter, use the cigarette lighter.
Do not pinch the power plug
cord in the door or window.
7. Start the vehicle. The vehicle must be running while using the
air compressor.
8. Turn the selector switch (B) clockwise to the Sealant + Air
position. 9. Press the on/off (A) button
to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (D) 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 inflates with
air only.
10. Inflate the tire to the recommended inflation
pressure using the pressure
gauge (D). The recommended
inflation pressure can be
found on the Tire and Loading
Information label. See Tire
Pressure on page 10‑54.
Page 387 of 462

Black plate (75,1)Buick LaCrosse Owner Manual - 2011
Vehicle Care 10-75
The pressure gauge (D) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor off
to get an accurate pressure
reading. The compressor may
be turned on/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 inflate
the tire. Remove the power plug
from the accessory power outlet
and unscrew the inflating hose
from the tire valve. See Roadside
Assistance Program (U.S.
and Canada) on page 13‑8 or
Roadside Assistance Program
(Mexico) on page 13‑10. 11. Press the on/off button (A)
to turn the tire sealant and
compressor kit off.
The tire is not sealed and
will continue to leak air until
the vehicle is driven and the
sealant is distributed in the tire;
therefore, Steps 12 through 18
must be done immediately after
Step 11.
Be careful while handling the
tire sealant and compressor
kit as it could be warm after
usage.
12. Unplug the power plug (G) from the accessory power outlet in
the vehicle.
13. Turn the sealant/air hose (F) counterclockwise to remove
it from the tire valve stem.
14. Replace the tire valve stem cap. 15. Return the sealant/air hose (F)
and the power plug (G) back in
their original locations.
16. If the flat tire was able to
inflate to the recommended
inflation pressure, remove the
maximum speed label from the
sealant canister and place it
in a highly visible location.
Do not exceed the speed on
this label 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 8 km (5 mi) to distribute the
sealant in the tire.

19. Stop at a safe location andcheck the tire pressure.
Refer to Steps 1 through 11
under “Using the Tire Sealant
and Compressor Kit without
Sealant to Inflate a Tire (Not
Punctured).”
If the tire pressure has fallen
more than 68 kPa (10 psi)
below the recommended
inflation pressure, stop
driving the vehicle. The tire
is too severely damaged and
the tire sealant cannot seal the
tire. See Roadside Assistance
Program (U.S. and Canada) on
page 13‑8 orRoadside
Assistance Program (Mexico)
on page 13‑10.
If the tire pressure has not
dropped more than 68 kPa
(10 psi) from the recommended
inflation pressure, use the
compressor kit to inflate the
tire to the recommended
inflation pressure. 20. Wipe off any sealant from the
wheel, tire, and vehicle.
21. Dispose of the used sealant canister and sealant/air
hose (F) assembly at a local
dealer or in accordance with
local state codes and practices.
22. Replace it with a new canister available from your dealer.
23. After temporarily sealing a tire using the tire sealant
and compressor kit, take
the vehicle to an authorized
dealer within 161 km (100 mi)
of driving to have the tire
repaired or replaced.Using the Tire Sealant and
Compressor Kit without
Sealant to Inflate a Tire
(Not Punctured)
To use the air compressor to inflate
a tire with air only and not sealant:
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. See Hazard
Warning Flashers on page 6‑4.

safety warnings.
1. Remove the tire sealant and compressor kit from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10‑79.
2. Unwrap the air only hose (E) and the power plug (G).
3. Place the kit on the ground. Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
4. Remove the tire valve stem cap from the flat tire by turning it
counterclockwise.
5. Attach the air only hose (E) onto the tire valve stem by turning it
clockwise until it is tight. 6. Plug the power plug (G) into the
accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets on page 5‑7.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.
If the vehicle only has a cigarette
lighter, use the cigarette lighter.
Do not pinch the power plug
cord in the door or window.
7. Start the vehicle. The vehicle must be running while using the
air compressor.
8. Turn the selector switch (B) counterclockwise to the Air
Only position.
9. Press the on/off (A) button to turn the compressor on.
The compressor will inflate the
tire with air only. 10. Inflate the tire to the
recommended inflation
pressure using the pressure
gauge (D). The recommended
inflation pressure can be
found on the Tire and Loading
Information label. See Tire
Pressure on page 10‑54.
The pressure gauge (D) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor
off to get an accurate reading.
The compressor may be turned
on/off until the correct pressure
is reached. If the tire is inflated
higher than the recommended
pressure, press the pressure
relief button (C), if equipped,
until the proper pressure
reading is reached. This option
is only functional when using
the air only hose (E).
