Using the Tire Sealant and
Compressor Kit without
Sealant to Inflate a Tire (Not
Punctured)
To use the air compressor to inflate
a tire with air only and not sealant:
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 on page 6‑4. See
If a Tire Goes Flat on
page 10‑69 for other important
safety warnings.
1. Remove the tire sealant and compressor kit from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10‑87.
2. Unwrap the air only hose (E) and the power plug (G).
3. Place the kit on the ground. Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
4. Remove the tire valve stem cap from the flat tire by turning it
counterclockwise.
5. Attach the air only hose (E) onto the tire valve stem by turning it
clockwise until it is tight. 6. Plug the power plug (G) into the
accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets on page 5‑7.
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.
7. Start the vehicle. The vehicle must be running while using the
air compressor.
8. Turn the selector switch (B) counterclockwise to the Air Only
position.
9. Press the on/off button (A) to turn the compressor on.
The compressor will inflate the
tire with air only.

Vehicle Care 10-77
10. Inflate the tire to therecommended inflation
pressure using the pressure
gauge (D). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure on page 10‑54.
The pressure gauge (D) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor off
to get an accurate reading. The
compressor may be turned on/
off until the correct pressure is
reached. If the tire is inflated
higher than the recommended
pressure, press the pressure
relief button (C), if equipped,
until the proper pressure
reading is reached. This option
is only functional when using
the air only hose (E). 11. Press the on/off button (A) to
turn the tire sealant and
compressor kit off.
Be careful while handling the
tire sealant and compressor kit
as it could be warm after
usage.
12. Unplug the power plug (G) from the accessory power outlet in
the vehicle.
13. Disconnect the air only hose (E) from the tire valve
stem, by turning it
counterclockwise, and replace
the tire valve stem cap.
14. Return the air only hose (E) and the power plug (G) back to
their original locations.
15. Return the equipment to its original storage location in the
vehicle.Removal and Installation of the
Sealant Canister
To remove the sealant canister:
1. Remove the plastic cover.
2. Unscrew the connector (B) from
the canister (A).
3. Pull up on the canister (A) to remove it.
4. Replace with a new canister which is available from your
dealer.

3. Place the kit on the ground.Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it
counterclockwise.
5. Attach the sealant/air hose (F) onto the tire valve stem. Turn it
clockwise until it is tight.
6. Plug the power plug (H) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets on page 5‑7.
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.
7. Start the vehicle. The vehicle must be running while using the
air compressor. 8. Turn the selector switch (A)
counterclockwise to the
Sealant + Air position.
9. Press the on/off button (B) to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (C) 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.
10. Inflate the tire to the recommended inflation
pressure using the pressure
gauge (C). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure on page 10‑54. The pressure gauge (C) 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.
Notice: 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 (U.S. and
Canada) on page 13‑7 or
Roadside Assistance Program
(Mexico) on page 13‑10.
11. Press the on/off button (B) to turn the tire sealant and
compressor kit off.

Vehicle Care 10-83
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 12–18 must be
done immediately after
Step 11.
Be careful while handling the
tire sealant and compressor kit
as it could be warm after
usage.
12. Unplug the power plug (H) from the accessory power outlet in
the vehicle.
13. Turn the sealant/air hose (F) counterclockwise to remove it
from the tire valve stem.
14. Replace the tire valve stem cap.
15. Replace the sealant/air hose (F), and the power
plug (H) back in their original
location.
16. If the flat tire was able to inflateto the recommended inflation
pressure, remove the
maximum speed label from the
tire sealant canister (E) and
place it in a highly visible
location. Do not exceed the
speed on this label 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 8 km (5 mi) to distribute the
sealant in the tire. 19. Stop at a safe location and
check the tire pressure. Refer
to Steps 1–11 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 Assistance
Program (U.S. and Canada) on
page 13‑7 orRoadside
Assistance Program (Mexico)
on page 13‑10.
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.

come off of the wheel cover.
The edge of the wheel cover
could be sharp, so do not try to
remove the cover with your bare
hands. Do not drop the cap or
lay it face down, as it could
become scratched or damaged.
Store the wheel cover in the
trunk until you have the flat tire
repaired or replaced.
3. Turn the wheel wrenchcounterclockwise to loosen all of
the wheel nuts, but do not

rust or dirt from places where the
wheel attaches to the vehicle. In
(Continued)
WARNING (Continued)
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.

{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.
11. Put the wheel nuts back on with the rounded end of the
nuts toward the wheel. Turn
each nut clockwise by hand
until the wheel is held against
the hub.
12. Lower the vehicle by turning the jack handle
counterclockwise. Lower the
jack completely.
{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 torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. See Capacities and
Specifications on page 12‑2 for
original equipment wheel nut
torque specifications.
Notice: 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 on
page 12‑2 for the wheel nut
torque specification.
