{ CAUTION
Overinflation could cause the
tire to rupture, and you or
others could be injured. Be
sure to read the inflator
instructions, and inflate the tire
to its recommended pressure.
Do not exceed 36 psi (248 kPa).
7. Push the On/Off switch (A) to the
I (on) position.
The kit will begin to inject sealant
into the tire. Sealant could leak
from the puncture hole until
the vehicle is driven and the hole
has sealed.
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. Inflate the tire to the
recommended inflation
pressure, found on the Tire
and Loading Information label.
See Inflation - Tire Pressure
on page 9-46.
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
inflates 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 inflate 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.
