Maintenance 217 Note: If your battery has a cover/shield, make sure it is reinstalled after the battery has been cleaned or replaced. Note: Electrical or electronic accessories or components added to the vehicle by the dealer or the owner may adversely affect battery performance and durability. Your vehicle is equipped with a Motorcraft® maintenance-free battery which normally does not require additional water during its life of service. For longer, trouble-free operation, keep the top of the battery clean and dry. Also, make certain the battery cables are always tightly fastened to the battery terminals. If you see any corrosion on the battery or terminals, remove the cables from the terminals and clean with a wire brush. You can neutralize the acid with a solution of baking soda and water. When the battery is disconnected or a new battery installed, the transmission must learn its adaptive strategy. As a result of this, the transmission may shift firmly. This operation is considered normal and will fully update transmission operation to its optimum shift feel. It is recommended that the negative battery cable terminal be disconnected from the battery if you plan to store your vehicle for an extended period of time. This will minimize the discharge of your battery during storage. For information on transmission operation after the battery has been disconnected, refer to Automatic transmission operation in the Driving chapter. Dual Batteries (If Equipped) Your vehicle may be equipped with a frame-mounted battery located on the passenger side frame rail, behind the front passenger door. This battery is connected in parallel with the battery in the engine compartment. Both batteries are used to start the vehicle. Because your vehicle's engine is electronically controlled by a computer, some control conditions are maintained by power from the battery. When the battery is disconnected or a new battery is installed, the engine must relearn its idle and fuel trim strategy for optimum driveability and performance. Flexible fuel vehicles (FFV) must also relearn the ethanol content of the fuel for optimum driveability and performance. To begin this process: 1. With the vehicle at a complete stop, set the parking brake. 2013 Econoline (eco) Owners Guide gf, 3rd Printing, May 2013 USA (fus)
