Checking it and changing it often is probably the single most important thing you can do to keep your car's engine in good condition.

Having working head and tail lights is absolutely crucial to your safety. Have them fixed as soon as possible whenever one isn't working and avoid driving with one light out, if at all possible.

Check the tire pressure, but also the alignment often. Tire pressure affects many aspects of your car, including the amount of fuel it uses, the handling and performance, as well as the comfort and smoothness of the ride. Rotate your tires after every other oil change. Proper tire rotation helps your tires to wear more evenly. Also, keep a check on the tread wear of your tires and get new tires when needed.

Check your transmission fluid according to your vehicle owner's manual recommendations. Top it up if needed, but do not over fill, as overfilling can damage your transmission.

If you don't have enough coolant, you run the risk of overheating your engine and damaging it. Keep the coolant level topped up, especially if you're going on a long trip during warmer months.

There are numerous belts in your vehicle. Be sure to check the rubber and the belt when you are performing your regular, under the hood maintenance.
