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 theTire 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 0389.
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 tireusing 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 to Inflate a Tire (Not
Punctured)
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
7. Pressure Deflation Button
8. Pressure Gauge
9. Power Plug
10. Air Only Hose
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 0147.
See If a Tire Goes Flat 0335 for
other important safety warnings. 1. Remove the compressor from
its storage location. See
Storing the Tire Sealant and
Compressor Kit 0342.
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.
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 air only hose (10) to the tire valve stem by turning it
clockwise until tight.
6. Plug the power plug (9) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets 098.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.

Mexico-13556230) - 2020 - CRC - 9/5/19
342 Vehicle Care
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. Press the on/off button (5) to turn the tire sealant and
compressor kit on.
The compressor will inflate the
tire with air only.
9. 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 0321.
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. See
Roadside
Assistance Program 0389.
10. Press the on/off button (5) to turn the tire sealant and
compressor kit off.
Be careful while handling the
compressor as it could be
warm after usage.
11. Unplug the power plug (9) from the accessory power outlet in
the vehicle. 12. Turn the air only hose (10)
counterclockwise to remove it
from the tire valve stem.
13. Replace the tire valve stem cap.
14. Return the air only hose (10) and power plug (9) back to
their original storage location.
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
The tire sealant and compressor kit
is in a bag in the rear compartment
storage area. 1. Open the liftgate. See Liftgate
0 21.
2. Fold the rear part of the load floor to the front.

4. Position the jack lift head at the jack location nearest the
flat tire.
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

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.
5. Attach the wheel wrench to the jack by fitting both ends over
one another.
6. Raise the vehicle by turning thewheel wrench clockwise. Raise
the vehicle far enough off the
ground so there is enough
room for the road tire to clear
the ground.7. Remove all of the wheel nuts.
8. 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

used; however, use a scraper
or wire brush later to remove
all rust or dirt.
9. Remove any rust or dirt from the wheel bolts, mounting
surfaces, and spare wheel.
10. 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.
11. Reinstall the wheel nuts. Tighten each nut by hand until
the wheel is held against
the hub.
12. Lower the vehicle by turning the jack handle
counterclockwise.
{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
