8. Check the air pressure gage (G).
If there is not a pressure reading
while the compressor is running,
check for leaks at the connection
between the tire valve stem and
the sealant/air hose (E).
9. Inate the tire to the
recommended ination pressure,
found on the Tire and Loading
Information label. See
Inflation - Tire Pressure on
page 9-49.
The pressure gage (G) will
initially read high while the
compressor injects the sealant
into the tire. Once the sealant
injection is complete, the
pressure will quickly drop. It will
start to rise again as the tire
inates with air.10. Turn the compressor off by
pushing the On/Off button (A)
to the I (off) position.
The pressure gage (G) reads
slightly high while the
compressor is on. Turn the
compressor off to get an
accurate reading. The
compressor may be turned on
and off until the correct pressure
is reached.
Notice:If the recommended
pressure cannot be reached after
approximately 15 minutes, the
vehicle should not be driven. The
tire is too severely damaged and
the tire sealant and compressor kit
cannot inate the tire. Remove the
air compressor accessory plug
from the accessory power outlet
and unscrew the sealant/air hose
from the tire valve or tire pressure
monitoring sensor valve. See
Roadside Assistance Program on
page 12-6.The tire is not sealed and will
continue to leak air until
the vehicle is driven and the
sealant is distributed in the tire.
Steps 11 through 19 must be
done right after Step 10.
Be careful while handling the
tire sealant and compressor kit
as they could be hot after
usage.
11. Unplug the air compressor
accessory plug (B) from the
accessory power outlet in
the vehicle.
12. Turn the sealant/air hose (E)
counterclockwise to remove.
13. Replace the tire valve
stem cap.
14. Stow the sealant/air hose (E)
and air compressor accessory
plug (B) in their original
locations.

Changing a Flat Tire
If a tire goes at, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the
hazard warning ashers.
{CAUTION
Changing a tire can be dangerous.
The vehicle can slip off the jack
and roll over or fall on you or other
people. You and they could be
badly injured or even killed. Find a
level place to change your tire.
To help prevent the vehicle from
moving:
1. Set the parking brake rmly.
2. Put an automatic
transmission shift lever in
P (Park), or shift a manual
transmission to 1 (First) or
R (Reverse).
(Continued)
CAUTION (Continued)
3. Turn off the engine and do
not restart while the vehicle
is raised.
4. Do not allow passengers to
remain in the vehicle.
To be certain the vehicle will not
move, put blocks at the front and
rear of the tire farthest away from
the one being changed. That
would be the tire on the other
side, at the opposite end of the
vehicle.When you have a at tire, place the
wheel block at the tire diagonally
across from the at tire.
