Do not engage the handbrake when you leave

Engaging the handbrake for a long time may result in the brake pads getting stuck to the discs or drums. Needless to say, if this happens, you'll be in some trouble the next time you drive the car. The smarter thing to do would be to leave the car in first gear and use wheel chocks, such as a piece of wood or even a brick, to keep it from rolling.

Spark plug care

If your car is going to be left idle for a long time, it's advisable to remove the spark plugs and spray a little oil into plug sockets before putting the plugs back again. This will help in preventing rust and keep the moisture away from the insides of the cylinder-head. You can also use fuel additives that add a protective coating to the insides of the engine. Of course, you should only do this if you're comfortable handling the mechanics of the car.

Clean the interiors before parking the car

People tend to leave trash in cars, including chocolate or biscuit wrappers (with crumbs inside), old newspapers, water bottles and so on. All of this could rot or, worse, attract rodents that can damage floor mats, seat covers and even wiring. So, clean the interior thoroughly and spray a little freshener. But don't use too much as even as it will stink in the closed confines over a long period.

Battery maintenance

It is advisable to remove the battery if your car is going to sit stationary for a long time. Also, you can apply petroleum jelly or grease on the terminals and the wire ends in order to prevent rusting. Ensure that the battery is fully charged and top up the water level. Store the battery in a cool and dry place, away from direct sunlight.

Jack up the car

Cars that have been stationary for long periods develop flat spots on their tyres. To avoid this, use four jacks (or blocks of wood or bricks) so that the car doesn't rest on the wheels. Sports cars with low profile tyres can be left without support for as much as two months without any damage to the tyres.
