AIR CONDITIONING AND AUDIO 4. Input your identification number by pushing buttons "1", "2" and "3" the desired number of times. Use the "1" button for the first digit, the "2" button for the second digit and the "3" button for the last digit. For example, if your number is 345, push the "1" button four times, the "2" button five times and "3" button six times. (pushing once will display "0"). If the display returns to "---" while inputting, try again. We recommend that your identification number be associated with something easy to remember. In case you are unsure of the number, write it in a notebook you normally carry. Do not leave it in your vehicle. 5. With your identification number appearing on the display, push the "SCAN" button and hold it in until "SEC" appears on the display. "SEC" will go off to indicate the system is set. If invalid buttons have been used, "ERR" will appear on the display before "SEC" appears. Try again from step 3. Once the system is set, the indicator light turns on and off with the ignition switch in "LOCK", and "SEC" will appear each time the ignition switch is turned from "LOCK" to "ACC". 120
