1. Make sure the tailgate operation is activated by the button on the dashboard
2. Push the key fob button twice. No need for extra-long pushes, but you have to learn the correct interval. This design makes it unlikely that you will open the tailgate unintentionally by keeping the key in your pocket -nothing stupid about it, just the opposite-.
3. If you want to avoid the Bleeping, use the tailgate manually by pushing the button on the tailgate twice and opening and closing by hand.
