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
0149.
See If a Tire Goes Flat 0437
for other important safety
warnings.
Do not remove any objects
that have penetrated the tire.

1. Remove the tire sealantcanister (4) and
compressor from its
storage location. See
Storing the Tire Sealant
and Compressor Kit 0446.
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 0101.

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 0422.
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 0487.
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 0487.
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.

Jump Starting
Jump Starting - North
America
For more information about
the vehicle battery, see
Battery - North America0399.
If the battery has run down,
try to use another vehicle and
some jumper cables to start
your vehicle. Be sure to use
the following steps to do it
safely.
{Warning
WARNING: Battery posts,
terminals and related
accessories can expose you
to chemicals including lead
and lead compounds, which
are known to the State of
California to cause cancer
and birth defects or other
reproductive harm. Wash
hands after handling. For
more information go to
www.P65Warnings.ca.gov. See California Proposition
65 Warning
01.
{Warning
Batteries can hurt you. They
can be dangerous because:
.They contain acid that can
burn you.
.They contain gas that can
explode or ignite.
.They contain enough
electricity to burn you.
If you do not follow these
steps exactly, some or all of
these things can hurt you.
Caution
Ignoring these steps could
result in costly damage to
the vehicle that would not
be covered by the vehicle
warranty. Trying to start the
vehicle by pushing or pulling
it will not work, and it could
damage the vehicle.
Caution
If the jumper cables are
connected or removed in the
wrong order, electrical
shorting may occur and
damage the vehicle. The
repairs would not be
covered by the vehicle
warranty. Always connect
and remove the jumper
cables in the correct order,
making sure that the cables
do not touch each other or
other metal.

4. Turn the ignition off. Turnoff all lights and
accessories in both
vehicles, except the hazard
warning flashers if needed.
{Warning
An electric fan can start up
even when the engine is not
running and can injure you.
Keep hands, clothing, and
tools away from any
underhood electric fan.
{Warning
Using a match near a
battery can cause battery
gas to explode. People have
been hurt doing this, and
some have been blinded.
Use a flashlight if you need
more light.
Battery fluid contains acid
that can burn you. Do not
get it on you. If you
accidentally get it in your

the place with water and get
medical help immediately.
{Warning
Fans or other moving engine
parts can injure you badly.
Keep your hands away from
moving parts once the
engine is running.
5. Connect one end of the red positive (+) cable to the
remote positive (+)
terminal on the discharged
battery.
6. Connect the other end of the red positive (+) cable to
the positive (+) terminal of
the good battery.
7. Connect one end of the black negative (–) cable to
the negative (–) terminal of
the good battery. Do not let the other end
touch anything until the
next step. The other end of
the negative (–) cable does
not go to the dead battery.
It goes to a heavy,
unpainted metal
engine part.
8. Connect the other end of the black negative (–) cable
to the negative (–)
grounding point for the
discharged battery.
9. Start the engine in the vehicle with the good
battery and run the engine
at idle speed for at least
four minutes.
10. Try to start the vehicle that had the dead battery.
If it will not start after a
few tries, it probably needs
service.
