Radio Messages
CAL ERR (Calibration Error): The audio system
has been calibrated for your vehicle from the
factory. If CAL ERR appears on the display, it
means that the radio has not been configured
properly for the vehicle and must be returned to
your dealer for service.
LOCKED: This message is displayed when the
®
THEFTLOCK system has locked up. Take
the vehicle to your dealer for service.
If any error occurs repeatedly, or if an error cannot
be corrected, contact your dealer.
Playing a Cassette Tape
The 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. The longer side with
the tape visible should face to the right. If you hear
nothing or hear a garbled sound, the tape may
not be in squarely. Press the eject button to
remove the tape and start over.
