yellowblue Accessory Inflator System (Option) Your vehicle may be equipped with an air inflator. With it, you can inflate things like air mattresses and basketballs, and you can also use it to bring your tires up to the proper pressure. The air inflator is located in the rear compartment on the driver's side. To remove the cover, pull the tab on the cover and pull it off. The air inflator kit is stored in the glove box or in the rear saddlebag, if your vehicle has this option. It includes a 20-foot (6 m) hose with an air pressure gage and nozzle adapters. 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. 2-81
