AUDIO SYSTEM AM-FM RADIO WITH CASSETTE PLAYER RADIO OPERATION To turn the radio on, turn the ignition key to ACC or ON. If you listen to the radio with the engine not running, turn the key to the ACC position. Radio reception is affected by station signal strength, distance from radio transmitter, buildings, bridges, mountains, and other external influences. Intermittent changes in reception quality normally are caused by these external influences. Using a cellular phone in or near the vehicle may influence radio reception quality.
