Using the Tire Sealant and Compressor
Kit to Temporarily Seal and Inflate a
Punctured Tire
When using the tire sealant and compressor
kit during cold temperatures, warm the kit
in a heated environment for five minutes.
This will help to inflate the tire faster.
If a tire goes flat, avoid further tire and
wheel damage by driving slowly to a level
place. Turn on the hazard warning flashers.
SeeHazard Warning Flashers 0134.
See If a Tire Goes Flat 0319 for other
important safety warnings.
Do not remove any objects that have
penetrated the tire.
1. Remove the tire sealant canister (4) and compressor from its storage location. See
Storing the Tire Sealant and Compressor
Kit 0326.
2. Remove the air only hose (10) and the power plug (9) from the bottom of the
compressor.
3. Place the compressor on the ground near the flat tire.
4. Attach the air only hose (10) to thesealant canister inlet valve (1) by turning
it clockwise until tight.
5. Slide the base of the tire sealantcanister (3) into the slot on the top of
the compressor (6) to hold it upright.
Make sure the tire valve stem is
positioned close to the ground so the
hose will reach it.
6. Remove the valve stem cap from the flat tire by turning it counterclockwise.
7. Attach the sealant/air hose (2) to the tirevalve stem by turning it clockwise until
tight.
8. Plug the power plug (9) into the accessory power outlet in the vehicle.
Unplug all items from other accessory
power outlets. See Power Outlets093.

Vehicle Care 323
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 (5) to turn the tire sealant and compressor kit on.
The compressor will inject sealant and air
into the tire.
The pressure gauge (8) 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 (8). The recommended inflation
pressure can be found on the Tire and
Loading Information label. See Tire
Pressure 0307.
The pressure gauge (8) 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
0 366.
12. Press the on/off button (5) to turn 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 (9) 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 (4) from the slot on top of the compressor (6).
17. Turn the air only hose (10) counterclockwise to remove it from the
tire sealant canister inlet valve (1).
18. Turn the sealant/air hose (2) clockwise onto the sealant canister inlet valve (1)
to prevent sealant leakage.
19. Return the air only hose (10) and power plug (9) back to their original storage
location.
20. If the flat tire was able to inflate to therecommended inflation pressure, remove
the maximum speed label from the
sealant canister and place it in a highly
visible location.

4. Turn the wing nut (3) counterclockwiseto remove the jack (1) and wheel
wrench (2). Place the tool container near
the tire being changed.
5. Remove the spare tire and place it next to the tire being changed.
Removing the Flat Tire and Installing the
Spare Tire
1. Do a safety check before proceeding. SeeIf a Tire Goes Flat 0319.
2. Turn the wheel wrench counterclockwise
to loosen all the wheel nuts, but do not
remove them yet.
3. Place the jack near the flat tire.
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.
4. Position the jack lift head at the jack location nearest the flat tire.
The jacking location is indicated by a half
circle notch in the metal flange. The jack
must not be used in any other position.
{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
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

Warning (Continued)
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.
Caution
Using a jack to raise the vehicle without
positioning it correctly could damage
your vehicle. When raising your vehicle
on a jack, be sure to position it correctly
under the frame and avoid contact with
the plastic molding.
5. Turn the wheel wrench clockwise to raisethe jack lift head until the slots in the
jack head fit into the metal flange
behind the cut out on the plastic
molding. Do not raise the vehicle yet.
6. Put the compact spare tire near you.
7. Turn the wrench clockwise in the jack to raise the vehicle. Raise the vehicle far
enough off the ground so that there is
enough room for the spare tire to fit
under the wheel well.
8. Remove all of the wheel nuts.
9. Remove the flat tire.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
cause wheel nuts to become loose
over 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 paper towel can be used; however,
use a scraper or wire brush later to
remove all rust or dirt.

10. Remove any rust or dirt from the wheelbolts, mounting surfaces, and spare
wheel.
11. Place the compact spare tire on the wheel-mounting surface.
{Warning
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.
12. Reinstall the wheel nuts. Tighten each nut by hand until the wheel is held
against the hub.
13. Lower the vehicle by turning the jack handle counterclockwise.
{Warning
Wheel nuts that are improperly or
incorrectly tightened can cause the
wheels to become loose or come off.
The wheel nuts should be tightened with
a torque wrench to the proper torque
specification after replacing. Follow the
(Continued)
Warning (Continued)
torque specification supplied by the
aftermarket manufacturer when using
accessory locking wheel nuts. See
Capacities and Specifications0359 for
original equipment wheel nut torque
specifications.
Caution
Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To
avoid expensive brake repairs, evenly
tighten the wheel nuts in the proper
sequence and to the proper torque
specification. See Capacities and
Specifications 0359 for the wheel nut
torque specification.14. Tighten the wheel nuts firmly in a crisscross sequence, as shown.
15. Lower the jack all the way and remove the jack from under the vehicle.
16. Tighten the wheel nuts firmly with the wheel wrench.
When reinstalling the wheel cover or center
cap on the full-size tire, tighten all six plastic
caps hand snug with the aid of the wheel
wrench and tighten them with the wheel
wrench an additional one-quarter of a turn.
