7. Attach the sealant/air hose (2)to the tire valve stem by turning
it clockwise until tight.
8. Plug the power plug (10) into the accessory power outlet in
the vehicle. Unplug all items
from other accessory power
outlets. See Power Outlets
0 103.
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.
9. Start the vehicle. The vehicle must be running while using
the air compressor.
10. Press the on/off button (8) to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (5) 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.
11. Inflate the tire to the recommended inflation
pressure using the pressure
gauge (5). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure 0272. The pressure gauge (5) 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.
Caution
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 0344.

12. Press the on/off button (8) toturn 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 13–21 must
be done immediately after
Step 12.
Be careful while handling the
tire sealant and compressor kit
as it could be warm after
usage.
13. Unplug the power plug (10) from the accessory power
outlet in the vehicle.
14. Turn the sealant/air hose (2) counterclockwise to remove it
from the tire valve stem.
15. Replace the tire valve stem cap. 16. Remove the tire sealant
canister (1) from the slot on top
of the compressor (9).
17. Turn the air only hose (11) counterclockwise to remove it
from the tire sealant canister
inlet valve (4).
18. Turn the sealant/air hose (2) clockwise onto the sealant
canister inlet valve (4) to
prevent sealant leakage.
19. Return the air only hose (11) and power plug (10) back to
their original storage location.
20. 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.
21. Return the equipment to its original storage location in the
vehicle.
22. Immediately drive the vehicle 8 km (5 mi) to distribute the
sealant in the tire.
23. Stop at a safe location and check the tire pressure. Refer
to Steps 1–10 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 0344.

298 Vehicle Care
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.
24. Wipe off any sealant from the wheel, tire, or vehicle.
25. Dispose of the used tire sealant canister (1) at a local
dealer or in accordance with
local state codes and practices.
26. Replace it with a new canister available from your dealer.
27. 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)

the wheel nuts, but do not
remove them yet.
5. Place the jack near the flat tire.
6. Put the compact spare tire near you.
{Warning
Getting under a vehicle when it is
lifted on a jack 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 the vehicle with the jack
improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
(Continued)
Warning (Continued)
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.
7. Attach the wrench to the jack by fitting the hex end of the
wrench over the hex head of
the jack. 8. Place the jack under the
vehicle.
Caution
Make sure that the jack lift head
is in the correct position or you
may damage your vehicle. The
repairs would not be covered by
your warranty.
9. Position the jack lift head at thejack location nearest the flat
tire. The location is indicated

The notches in the jack must
align with the notch in the
rocker pinch weld. The jack lift
head lifts on the inward side of
the pinch weld flange.
The jack must not be used in

{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 a crash. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
