Before disconnecting the battery, make sure you have the anti-theft codes for the radio and the navigation system, and write down the frequencies for the radio's preset buttons.
After reconnecting the battery, you have to wait to get the initial signal from the satellite. It will take about 10 minutes.
After reconnecting the battery, do the power window control unit resetting procedure (see RESETTING THE POWER WINDOW CONTROL UNIT ).
Before returning the vehicle to the customer, enter the radio code, then enter the customer's radio station presets, and set the clock.
