WARNING: This page is about a different car, the 2004 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
  1. PRECAUTION FOR DISCONNECTING THE BATTERY CABLE 
    NOTE: When disconnecting the negative (-) battery terminal, initialize the following systems after the terminal is reconnected. 
    SYSTEM NAME

    System Name Action
    Power Window Control System INITIALIZATION
    Sliding Roof System INITIALIZATION
  2. PRECAUTION OF HEADLIGHT BULB REPLACEMENT 
    1. If even a thin film of oil is left on the surface of the halogen lamp, its service life will be shortened because the lamp will burn at a higher temperature.
    2. Handle any halogen lamp with great care. Dropping, hitting or damaging the bulb, in any way, may result in it exploding and shattering because the internal pressure is high.
    3. Always prepare a new bulb for immediate replacement. While replacing the bulb, the lens may attract dust and moisture if removed from the vehicle for too long.
    4. Always use a bulb of the same wattage for replacement.
    5. Firmly reinstall the socket after bulb replacement. The lens may become cloudy or the light cavity may fill with water through the gaps around the socket.
