8. Start the vehicle. The vehicle must be
running while using the air compressor.
9. Press the on/off button (4) to turn the
tire sealant and compressor kit on.
The compressor will inject sealant and air
into the tire.
The pressure gauge (6) 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.
10. Inflate the tire to the recommended
inflation pressure using the pressure
gauge (6). The recommended inflation
pressure can be found on the Tire and
Loading Information label. See Tire
Pressure 0 294.
The pressure gauge (6) 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.
11. Press the on/off button (4) 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 12 20 must be done
immediately after Step 11.
Be careful while handling the tire sealant
and compressor kit as it could be warm
after usage.
12. Unplug the power plug (7) from the
accessory power outlet in the vehicle.
13. Turn the sealant/air hose (2)
counterclockwise to remove it from the
tire valve stem.
14. Replace the tire valve stem cap.
Vehicle Care
15. Turn the air only hose (8)
counterclockwise to remove it from the
tire sealant canister inlet valve (1).
16. Replace the tire sealant canister inlet
valve (1) cap.
17. Return the air only hose (8) and power
plug (7) back to their original storage
location.
18. 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.
19. Return the equipment to its original
storage location in the vehicle.
20. Immediately drive the vehicle 8 km
(5 mi) to distribute the sealant in
the tire.
