Buick LaCrosse Owner's Manual page 421

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 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 (H) 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. Replace the sealant/air
hose (F), and the power
plug (H) back in their original
location.
16. If the flat tire was able to inflate
to the recommended inflation
pressure, remove the
maximum speed label from the
tire sealant canister (E) 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 and
check the tire pressure. Refer
to Steps 1 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
or
.
If the tire pressure has not
dropped more than 68 kPa
(10 psi) from the recommended
inflation pressure, inflate the
tire to the recommended
inflation pressure.
