XM™ Satellite Radio Service XM Satellite Radio Service gives digital radio reception from coast-to-coast in the 48 contiguous United States, and in Canada. Just as with FM, tall buildings or hills can interfere with satellite radio signals, causing the sound to fade in and out. In addition, traveling or standing under heavy foliage, bridges, garages, or tunnels may cause loss of the XM signal for a period of time. Multi-Band Antenna The multi-band antenna is located on the roof of the vehicle. The antenna is used for the AM/FM radio, OnStar® and the XM™ Satellite Radio Service System, if the vehicle has these features. Keep the antenna clear of obstructions for clear reception. If the vehicle has a sunroof, the performance of the AM/FM radio, OnStar®, and the XM system may be affected if the sunroof is open. Cellular Phone Usage Cellular phone usage may cause interference with the vehicle's radio. This interference may occur when making or receiving phone calls, charging the phone's battery, or simply having the phone on. This interference causes an increased level of static while listening to the radio. If static is received while listening to the radio, unplug the cellular phone and turn it off. 3-119
