The air inflator kit is located in the glove compartment. The kit includes a 22-foot (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. See "Electronically Controlled Air Suspension System" in the Index. To reinstall the cover, line up the tabs at the back of the cover, put it in place and latch the tabs. A continuous flashing indicator light may also indicate a malfunction in the air suspension system. See "Electronically Controlled Air Suspension System" in the Index. CAUTION: Inflating something too much can make it explode, and you or others could be injured. Be sure to read the inflator instructions, and inflate any object only to its recommended pressure. 2-64
