When reconnecting the battery follow these steps: *Ensure all doors and tailgate are shut, and the key is more than 15m away from the vehicle. * Reconnect the battery by reversing the steps in the video. *Wait a further 3 minutes (do not open doors). *Switch on the side lights through the driver&window. *Again through the window put the key Fob in the car or in the Fob Reader, press the Start Stop button without pressing any pedals.
