plug (H) back in their original location.
16. If the at tire was
able to inate to the
recommended ination
pressure, remove
the maximum speed
label from the sealant
canister (E) and
place it in a highly
visible location.
The label is a reminder not to exceed 55 mph
(90 km/h) 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 5 miles (8 km) to
distribute the sealant in the tire.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 Service 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

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 the vehicle has a at tire (B), use the following
example as a guide to assist you in the placement
of wheel blocks (A).A. Wheel Block

1. Do a safety check before proceeding. SeeChanging
a Flat Tire on page 5-96for more information.
2. Loosen the wheel nuts, but do not remove them
yet, using the wheel wrench. Turn the handle
about 180 degrees, then return the handle back to
the starting position. This avoids taking the
wrench off the lug nut for each turn.3. Find the jacking location using the diagram above

through the jack and the at end through the
wheel wrench.
{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under a
vehicle when it is supported only by a jack.
{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without the
appropriate safety equipment and training. If a jack
is provided with the vehicle, it is designed only for
changing a at tire. If it is used for anything else,
you or others could be badly injured or killed if the
vehicle slips off the jack. If a jack is provided with
the vehicle, only use it for changing a at tire.

{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal injury
and vehicle damage, be sure to t the jack lift
head into the proper location before raising the
vehicle.
Notice:If you position the jack under the rocker
molding and attempt to raise the vehicle, you could
break the molding and/or cause other damage to
your vehicle. Always position the jack so that when
the jack head is raised, it will t rmly in the
notch located inboard from the rocker molding.

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 5-96.
{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.
