For the best operation of the cassette tape deck, do not use cassette tapes that have longer than 90 minutes of total playback time. Cassette tapes longer than 90 minutes may slip or jam.

Tape Head and Capstan Cleaning

Important: If a ribbon type cleaner is not used, cycle the tape player cleaner at least 3 times for each cleaning. This is necessary due to the tape tension being monitored. The tape player unit will read tape cleaners without a ribbon as a broken tape. The tape player unit will reject tape cleaners without a ribbon.

Clean the following 2 components on a tape player:

    • The head
    • The capstan

Since you are able to reach the above parts through the tape door, leave the tape player in the vehicle. Perform this cleaning service after every 15 hours of cassette operation.

Use a cotton swab dipped in ordinary rubbing alcohol in order to clean the following components:

    • The head
    • The capstan

Instead of using a cotton swab, you may purchase a cleaning cassette kit. Follow the instructions on the kit in order to clean the tape player.

Do not touch the tape head using magnetized tools. If the head is magnetized, every cassette you play in the player will degrade.

Demagnetize the play-back head in the cassette tape deck every 50 hours of cassette play. Follow the procedure provided by the manufacturer of the demagnetizer tool in order to demagnetize the play-back head.

The cartridge manufacturer performs the following services on cassette tapes:

    • Service of tapes
    • Warranty of tapes

    • Extreme heat
    • Direct sunlight

Ventilation Tips

Clear the hood and front air inlet of the following obstructions:

    • Ice
    • Snow
    • Leaves
    • Any other obstruction

If the hood and front air inlet are clear, the heater and defroster will work more efficiently. A clear hood and front air inlet will reduce the chance of fogging the following areas:

    • The inside of the windows
    • The stereo components
