Ford Customer Service has advised to disconnect the 12 volt battery in the trunk of the Fusion Hybrid when leaving the car unused for a period of time. The manual refers to 30 day period but this could also apply to 2 weeks. You can also try a trickle charger on the battery. There are other tips in the manual under topic storage/storing the car. Most of us dont think of the word storage when we leave a car for a few weeks so it is not easy to find this info in the manual. Let us know how this works for you, please!
