If you're a snowbird flying south, a member of the military heading for duty or a professional accepting an assignment overseas, you have to ask, "What will I do with my car while I'm away?"

Frankly, the components in your car are like the muscles in your body: They work best when used regularly. For example, automatic transmissions are designed for "splash lubrication"-normal use keeps the parts coated. For that reason alone, most automakers discourage long periods of inactivity. Instead, they recommend "exercising" the vehicle every two weeks or so, even if only for short distances.

But suppose a family member or trusted friend isn't available for such workouts. Then take these steps if you plan to store the car for a month or more:

Fill the tank and add stabilizer. Gasoline sours when exposed to oxygen, forming compounds that gum up parts and attack plastic and rubber seals. A full tank traps less air. Gasoline stabilizer (available at auto parts stores or mower shops) does just what its name implies: It reduces oxidation.

Disconnect the battery. The clock, engine computer and other systems continue to suck juice from the battery even with the engine off. You don't want to return to a dead battery-or worse. As the battery discharges, the freezing point of the electrolyte solution rises. In an unheated garage in winter, a discharged battery can freeze solid, and that's the end of it. Store it indoors.

Take a load off. Overinflate the tires to about 45 psi for extra support. For long storage periods, invest in a set of jack stands; lift the car at points of hoist contact to take the weight off the tires. Don't set the parking brake; the cables might corrode, causing the brake to stick.

Clean it and cover it. Vacuum the interior thoroughly, removing every crumb from the carpet, the seats and especially the bights (the crevice between the seat cushions and the backs). Don't leave the least smidgen of food that would attract mice, ants or other pests. Wash, dry and wax the exterior and cover the car with a breathable, non-scratch cover.
