Chevrolet 1998 Prizm Owner's Manual page 150

When using a scrubbing action, non-abrasive cleaning
cassette, it is normal for the cassette to eject because
your
unit is equipped with a cut tape detection feature
and a cleaning cassette may appear as a broken tape. To
prevent the cleaning cassette from being ejected, use the
following steps.
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.
3. Press and hold the TAPE button for five seconds.
The tape symbol
on
the display will flash for
two 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 cut
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 EJECT for
five seconds to reset the CLEAN indicator. The radio
will display
---
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.
