2002 GMC Savana Van Owner's Manual - Page 188

If your vehicle is equipped with the AM-FM Stereo with Cassette Tape and Compact Disc Player with Radio Data System and Programmable Equalization do the following: 1. Turn the ignition to RUN or ACCESSORY. 2. Turn the radio off. 3. Press and hold the TAPE CD button for five seconds. READY will appear on the display for five seconds. 4. Insert the scrubbing action cleaning cassette. 5. Eject the cleaning cassette after the manufacturer's recommended cleaning time. When the cleaning cassette has been ejected, the broken tape detection feature is active again. You may also choose a non-scrubbing action, wet-type cleaner which uses a cassette with a fabric belt to clean the tape head. This type of cleaning cassette will not eject on its own. A non-scrubbing action cleaner may not clean as thoroughly as the scrubbing type cleaner. The use of a non-scrubbing action, dry-type cleaning cassette is not recommended. After you clean the player, press and hold the cassette eject symbol or the EJT button for five seconds to reset the CLEAN or CLN indicator. The radio will display CLEANED or --- to show the indicator was reset. Cassettes are subject to wear and the sound quality may degrade over time. Always make sure the cassette tape is in good condition before you have your tape player serviced. 3-49
