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 (8) to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (5) 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 (5). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure 0281. The pressure gauge (5) 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 0350.
12. Press the on/off button (8) 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 (10) 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 (1) from the slot on top
of the compressor (9).
17. Turn the air only hose (11) counterclockwise to remove it
from the tire sealant canister
inlet valve (4).

18. Turn the sealant/air hose (2)clockwise onto the sealant
canister inlet valve (4) to
prevent sealant leakage.
19. Return the air only hose (11) and power plug (10) 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.
See Roadside Assistance
Program 0350.
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 (1) 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.

stem cap.
14. Return the air only hose (11) and power plug (10) back to

15. Return the equipment to its original storage location in the
vehicle.
The tire sealant and compressor kit
has accessory adapters located in a
compartment on the bottom of its
housing that can be used to inflate
air mattresses, balls, etc.
Storing the Tire Sealant
and Compressor Kit (With
Subwoofer)
To access the tire sealant and
compressor kit:
1. Open the liftgate. See Liftgate
0 42.
2. Lift the cover.

2. Screw the extension bolt ontothe end of the spare tire stow
bolt by hand.
3. Replace the foam, jack, and tools in their original storage
location.
4. Remove the insulator pad, if equipped, and place it over
the foam holder to protect the
wheel of the flat tire from
the jack.
5. Place the tire over the extension bolt facing up.
6. Turn the retainer nut clockwise to secure the tire. 7. Place the floor cover on the
wheel.
The compact spare is for temporary
use only. Replace the compact
spare tire with a full-size tire as
soon as you can.
Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a
crash and you or others could be
injured. Use only one compact
spare tire at a time.
If this vehicle has a compact spare
tire, it was fully inflated when new;
however, it can lose air over time.
Check the inflation pressure
regularly. It should be 420 kPa
(60 psi).
Stop as soon as possible and check
that the spare tire is correctly
inflated after being installed on the vehicle. The compact spare tire is
designed for temporary use only.
The vehicle will perform differently
with the spare tire installed and it is
recommended that the vehicle
speed be limited to 80 km/h
(50 mph). To conserve the tread of
the spare tire, have the standard tire
repaired or replaced as soon as
convenient and return the spare tire
to the storage area.
When using a compact spare tire,
the AWD (if equipped), ABS, and
Traction Control systems may
engage until the spare tire is
recognized by the vehicle,
especially on slippery roads. Adjust
driving to reduce possible
wheel slip.
Caution
When the compact spare is
installed, do not take the vehicle
through an automatic car wash
with guide rails. The compact
spare can get caught on the rails
which can damage the tire, wheel,
and other parts of the vehicle.
