Remote Cassette Tape Player (If Equipped)
If your vehicle has this feature it is located in the center
console extension.
Your tape player is built to work best with tapes that
are up to 30 to 45 minutes long on each side. Tapes
longer than that are so thin they may not work well
in this player.
To load a cassette tape with the ignition off, first press
EJECT on the remote player. Then, insert the cassette
tape. The tape will play if the ignition is on but the radio
is off.
