environment (shoulder slope,
road debris, etc.). Removal of
some weight may improve the
ability to fit the jack under the
vehicle at the correct jacking
location.
{Warning
Changing a tire can be
dangerous. The vehicle can
slip off the jack and roll over
or fall causing injury or
death. Find a level place to
change the tire. To help
prevent the vehicle from
moving:1. Set the parking brake firmly.
2. Put the vehicle in P (Park).
3. Turn the vehicle off and do not restart the vehicle
while it is raised.
4. Do not allow passengers to remain in the vehicle.

Warning (Continued)
5. Place wheel blocks,if equipped, on both sides
of the tire at the
opposite corner of the
tire being changed.
This vehicle may come with a
jack and spare tire or a tire
sealant and compressor kit. To
use the jacking equipment to
change a spare tire safely,
follow the instructions below.
Then see Tire Changing 0398.
To use the tire sealant and
compressor kit, see Tire
Sealant and Compressor Kit
0 390.
When the vehicle has a flat
tire (2), use the following
example as a guide to assist
you in the placement of wheel
blocks (1), if equipped.

{Warning
Idling a vehicle in an
enclosed area with poor
ventilation is dangerous.
Engine exhaust may enter
the vehicle. Engine exhaust
contains carbon monoxide
(CO) which cannot be seen
or smelled. It can cause (Continued)

unconsciousness and even
death. Never run the engine
in an enclosed area that has
no fresh air ventilation. For
more information, see
Engine Exhaust0256.
{Warning
Overinflating a tire could
cause the tire to rupture
and you or others could be
injured. Be sure to read and
follow the tire sealant and
compressor kit instructions
and inflate the tire to its
recommended pressure. Do
not exceed the
recommended pressure.
{Warning
Storing the tire sealant and
compressor kit or other
equipment in the passenger

Warning (Continued)
compartment of the vehicle
could cause injury. In a
sudden stop or collision,
loose equipment could strike
someone. Store the tire
sealant and compressor kit
in its original location.
If this vehicle has a tire sealant
and compressor kit, there may
not be a spare tire or tire
changing equipment, and on
some vehicles there may not
be a place to store a tire.
The tire sealant and
compressor can be used to
temporarily seal punctures up
to 6 mm (0.25 in) in the tread
area of the tire. It can also be
used to inflate an
underinflated tire.
If the tire has been separated
from the wheel, has damaged
sidewalls, or has a large
puncture, the tire is too
severely damaged for the tire sealant and compressor kit to
be effective. See Roadside
Assistance Program
0439.
Read and follow all of the tire
sealant and compressor kit
instructions.
The kit includes:
1. Sealant Canister Inlet Valve
2. Sealant/Air Hose
3. Base of Sealant Canister
4. Tire Sealant Canister
5. On/Off Button
6. Slot on Top of Compressor

Tire Sealant
Read and follow the safe
handling instructions on the
label adhered to the tire
sealant canister (4).
Check the tire sealant
expiration date on the tire
sealant canister. The tire
sealant canister (4) should be
replaced before its expiration date. Replacement tire sealant
canisters are available at your
local dealer.
There is only enough sealant
to seal one tire. After usage,
the tire sealant canister must
be replaced.
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. See Hazard Warning
Flashers
0152.
See If a Tire Goes Flat 0389
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 0398.
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 the sealant canister
inlet valve (1) by turning it
clockwise until tight.
5. Slide the base of the tiresealant canister (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/airhose (2) to the tire valve
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 Outlets 0115. 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 0372.
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 (Continued)
Caution (Continued)
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 0439.
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 toinflate 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 0439.
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 (4) 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.
