{Warning
Plain water, or other liquids such
as alcohol, can boil before the
proper coolant mixture will. With
plain water or the wrong mixture,
the engine could get too hot but
there would not be an overheat
warning. The engine could catch
fire and you or others could be
burned.
Caution
Failure to follow the specific
coolant fill procedure could cause
the engine to overheat and could
cause system damage. If coolant
is not visible in the surge tank,
contact your dealer.
If no problem is found, check to see
if coolant is visible in the coolant
surge tank. If coolant is visible but
the coolant level is not at or above
the indicated mark, add a 50/
50 mixture of clean, drinkable water and DEX-COOL coolant. Be sure
the cooling system, including the
coolant surge tank pressure cap, is
cool before you do it.
1. Remove the coolant surge tank
pressure cap when the cooling
system, including the coolant
surge tank pressure cap and
upper radiator hose, is no
longer hot.
Turn the pressure cap slowly
counterclockwise about
one-quarter of a turn. If you
hear a hiss, wait for that to
stop. This will allow any
pressure still left to be vented
out the discharge hose.
2. Keep turning the pressure cap slowly and remove it.
3. Fill the coolant surge tank with
the proper mixture to the
indicated level mark.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until you
can feel the upper radiator
hose getting hot. Watch out for
the engine cooling fan.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge
tank until the level reaches the
indicated level mark.

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. SeeHazard
Warning Flashers 0168.
See If a Tire Goes Flat 0340 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 0348.
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) tothe sealant canister inlet
valve (1) by turning it clockwise
until tight.
5. Slide the base of the tire
sealant 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.

Mexico-12146149) - 2019 - crc - 7/30/18
Vehicle Care 345
7. Attach the sealant/air hose (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 0124.
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 0326.
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 0394.
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.

346 Vehicle Care
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 0394.
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.

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

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 0326.
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

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.
