-Car audio system operating hints If you pushed any wrong buttons, "Err" and the number of errors you have made will appear on the display before "SEC" does. Go back to step 2 and try again. If the display returns to "- - -" while you are entering the code, go back to step 3. To make sure the security code has been accepted, turn the ignition to "LOCK" and then back to "ACC". "SEC" should appear on the display. NOTICE To ensure the correct audio system operation: zBe careful not to spill beverages over the audio system. zDo not put anything other than a cassette tape or CD magazine into the cassette tape slot or CD changer. ILLUMINATION CONTROL LOGIC When the instrument panel lights are on, the letters on operable buttons of the mode in current use light up. On some audio units, the mode selection and eject buttons also light up. On some audio-units, when a cassette tape and compact disc are not in the slot the letters on the tape and disc mode buttons do not light up, but the slot lights up for easy access. Once a cassette tape or compact disc is inserted, the letters on the tape or disc mode buttons light up, and the slot stops illuminating. NOTICE 4. The three-digit code should be on the display. Push and hold in "SCAN" until the display goes dark. (At first, "SEC" will appear on the display.) A tenth error will activate the anti-theft system and "HELP" will appear on the display. The audio system will be completely inoperable. At this time, the anti-theft light also comes on. If this occurs, contact your Toyota dealer. 111
