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.
