Transmission fluid should be checked while the engine is warm and running. Checking this fluid is much like checking the oil. Pull the dipstick out and wipe the fluid off of it. Reinsert the dipstick and pull it back out to check the level. To refill the transmission fluid, use a funnel to pour it into the transmission fluid hole.

Air filters are important to check and replace regularly. When you pull the air filter out, check to see if you can see through it. If you can't, it’s dirty and time for a change.

Make sure all your belts are in good condition. They should not be cracked or frayed. The tension in them also needs to be checked. Push on them a little bit to check this. They should all give a little, but only about half an inch. If they give more they're too loose and if they don't give that much, they're too tight.

All of the hoses and wiring need to be checked under the hood. Look them over and see if they have any damage. If they do, they should be taken out and replaced.

Wiper blades are one of the biggest assistance in driving since they determine your visibility. Wipers should wipe liquids off the windshield in a clean, streak-free manner. If they are cracked, frayed, or leaving your windshield in poor condition after use, it’s time to change them.

Tires should also be checked. They should only be checked when the car has not been driven for at least three hours so the tires are cold. Using a gauge made to measure the pressure in your tires, make sure the pressure is up to manufacturer’s specifications. If it’s down, put some air in the tires. Don't forget to do the spare as well. If the pressure level is too high, you can release some by pressing on the little pin found in the middle of the tire valve.

Turn your headlights and four-way signals on. Get out of the car and walk around to make sure they are all working.
