WARNING: This page is about a different car, the 2006 Toyota Corolla and 2005 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.

HANDLING AND OPERATIONAL PRECAUTIONS
1. Explain to the customer that when the negative terminal is disconnected from the battery, the AM/FM channel presets in the radio receiver are cleared. If necessary, make a note of the recorded channel information before the negative terminal is disconnected, then reset the information after the negative terminal is reconnected.
2. The removal/installation of the radio receiver should be performed after all cassette tapes, audio CDs, and map discs are ejected from the radio receiver.
  HINT:
  
  If a cassette tape, audio CD, or map disc cannot be ejected due to a malfunction in the radio receiver, do not attempt to remove it forcefully. Bring the vehicle to a repair center.
3. Fasten the ground bolt securely when the antenna cord is removed or installed.
  HINT:
  
  Failure to fasten the ground bolt securely causes noise when receiving radio waves.
4. Do not touch the cone paper of the speaker.
