The air inflator kit may be located in the glove box.
The kit includes a 22 ft (6.7 m) hose with three nozzle
adapters.
To use the air inflator, attach the appropriate nozzle
adapter to the end of the hose if required. Then attach
that end of the hose to the object you wish to inflate.
Attach the other end of the hose to the outlet.
Press and release the switch to turn the air inflator on.
The indicator light will remain on when the inflator is
running.
The system has an internal clock to prevent overheating.
The system will allow about five minutes of running
time, then the compressor will stop. The indicator light
will then begin to flash. When the indicator is off,
the inflator can be started again by pressing the switch.
If the compressor is still hot, it may only run for a
short time before shutting off again.
Press and release the switch to turn the inflator off. Place
the inflator kit tools in the pouch and store it properly.
Remove the inflator hose from the outlet during loading
and unloading. Load leveling will not function with the
inflator hose attached to the inflator outlet.
