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
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 Service on page 8‑8.
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.
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 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 a 161 km (100 miles) of
driving to have the tire repaired or replaced.Using the Tire Sealant and Compressor

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:

WARNING: (Continued)
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 flat tire (B), use the following
example as a guide to assist you in the placement of
wheel blocks (A).

3. Find the vehicle's jacking location using thediagram above and corresponding V–shaped
notches located in the plastic molding on the
vehicle's frame. The notches in the plastic molding
are marked with a triangle shape.
4. Attach the wheel wrench to the jack.
{WARNING:
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.
{WARNING:
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 fit the jack
lift head into the proper location before raising the
vehicle.

{WARNING:
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 flat 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 flat tire.
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 fit firmly in the notch
located inboard from the rocker molding.
5. Turn the wheel wrench counterclockwise to lower the jack lift head until the jack fits under the
vehicle.
6. Raise the jack by turning the wheel wrenchclockwise until the slots in the jack head fit into the
metal flange located behind the triangle on the
plastic molding as shown.
7. Put the compact spare tire near you.

{WARNING:
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
