Maintenance and Specifications BATTERY Your vehicle is equipped with a Motorcraft maintenance-free battery which normally does not require additional water during its life of service. However, for severe usage or in high temperature climates, check the battery electrolyte level. Refer to the scheduled maintenance information for the service interval schedules. Keep the electrolyte level in each cell up to the "level indicator". Do not overfill the battery cells. If the electrolyte level in the battery is low, you can add plain tap water to the battery, as long as you do not use hard water (water with a high mineral or alkali content). If possible, however, try to only fill the battery cells with distilled water. If the battery needs water often, have the charging system checked. If your battery has a cover/shield, make sure it is reinstalled after the battery has been cleaned or replaced. 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. Note: Electrical or electronic accessories or components added to the vehicle by the dealer or the owner may adversely affect battery performance and durability. 354 2006 Navigator (nav) Owners Guide (post-2002-fmt) USA (fus)
