19. 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 a Tire (Not Punctured).”
If the tire pressure has fallen more than 10 psi
(68 kPa) below the recommended ination pressure,
stop driving the vehicle. The tire is too severely
damaged and the tire sealant cannot seal the tire.
SeeRoadside Assistance Program on page 7-7.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, inate the tire to the recommended
ination pressure.
20. Wipe off any sealant from the wheel, tire, and
vehicle.
21. Dispose of the used sealant canister (E) and sealant/
air hose (F) assembly at a local dealer/retailer or in
accordance with local state codes and practices.
22. Replace it with a new canister available from your
dealer/retailer.
23. After temporarily sealing a tire using the tire sealant
and compressor kit, take the vehicle to an authorized
dealer/retailer within a 100 miles (161 km) of driving
to have the tire repaired or replaced.Using the Tire Sealant and Compressor

by driving slowly to a level place. Turn on the hazard
warning ashers. SeeHazard Warning Flashers

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

{CAUTION:
Rust or dirt on a wheel, or on the parts to which it is
fastened, can make wheel nuts become loose after
time. The wheel could come off and cause an
accident. When changing a wheel, remove any rust
or dirt from places where the wheel attaches to the
vehicle. In an emergency, 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 page 5-88.9. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
10. Place the spare tire on the wheel-mounting surface.
{CAUTION:
Never use oil or grease on bolts or nuts because
the nuts might come loose. The vehicle’s wheel
could fall off, causing a crash.
11. Put the nuts on by hand. Make sure the cone
shaped end is toward the wheel.
12. Tighten each nut by hand until the wheel is held
against the hub. If a nut cannot be turned by
hand, use the wheel wrench and see your dealer
as soon as possible.
