If the air inflator system does not turn on, the fuse may be blown or installed incorrectly. See "Fuses and Circuit Breakers" in the Index or see your dealer for service. Your air inflator will automatically shut off after about 10 minutes. To reset, press the ON switch again. Don't run your air inflator for longer than 30 minutes at one time. If you do, you may damage the system. After 30 minutes, wait at least 10 minutes before restarting the air inflator. To turn off the air inflator, press OFF and detach the hose, first from the inflated object, then from the outlet. Replace the protective cap. Place the inflator kit tools in the pouch and store it properly. To replace the cover, line up the tabs at the back of the cover and put it in place. These circuits are protected by a fuse and have maximum current levels. NOTICE: When using the accessory power outlets, maximum electrical load must not exceed 20 amps. Always turn off any electrical equipment when not in use. Leaving electrical equipment on for extended periods will drain your battery. Cellular Telephone (Option) Your vehicle has been prewired for dealer installation of a dual-mode (analog/digital) cellular telephone. A fixed mobile or a portable hand-held system is available. Voice activation and hands-free operation are standard features. For more information, contact your GMC dealer. A user's guide is provided with the telephone. Accessory Power Outlets With the accessory power outlets, you can plug in auxiliary electrical equipment. There are four accessory power outlets located throughout the vehicle. Two are near the lower center part of the instrument panel, one is located in the lower rear of the center console and the other is located in the rear of the vehicle in the air inflator compartment. Follow the proper installation instructions that are included with any electrical equipment you install. 2-55
