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) tothe 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 0104.
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 0279.
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.
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 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.
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.Using the Tire Sealant and
Compressor Kit without Sealant

spare tire.
Place the spare tire next to the
tire being changed.
5. The jack and tools are stored below the spare tire.
Remove them from their
container and place them near
the tire being changed.
Removing the Flat Tire and
Installing the Spare Tire
1. Do a safety check beforeproceeding. See If a Tire Goes Flat
0 292. 2. For vehicles equipped with a
wheel cover or center cap, pull
the cover or center cap away
from the wheel to remove it.
Store the wheel cover in the
cargo area until the flat tire is
repaired or replaced.
If the vehicle has a center cap
with wheel nut caps, the wheel
nut caps are designed to stay
with the center cap after they are
loosened.
Remove the entire center cap if
the wheel has a smooth center
cap. Place the chisel end of the
wheel wrench in the slot on the
wheel, and gently pry it off.
3. Turn the wheel wrench
counterclockwise to loosen all
the wheel nuts, but do not
remove them yet.
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.

302 VEHICLE CARE
Locate the notch on the sheet
metal weld flange. Place the
center of the jack lift head on the
center of the sheet metal notch.
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 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 clockwiseto raise the jack until the slot in
the jack lift head fits into the
metal flange located behind the
cut out on the plastic molding.

VEHICLE CARE 303
Do not raise the vehicle yet.
6. Put the compact spare tire near you.
7. Raise the vehicle by turning the jack handle clockwise. Raise the
vehicle far enough off the ground
so there is enough room for the
road tire to clear the ground.
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 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 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 wheel bolts, 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.
