Let’s see a show of hands: who knows how to repair your car’s transmission or overhaul your engine? If so, go directly to the last paragraph, pull out your wrenches, and dive under the hood with your kids. For the rest of us, here are some simple, easy-to-follow tips for keeping your car running smoothly.

Think G-O-B: gas, oil, brakes. Let your kids learn how to put gas in the car, top off the tank, and pay for the purchase. Show them how to pull out the dipstick—on level ground after the car has had time to cool—and read the oil level. Teach them to add a quart when the level’s low. Be sure you take them with you when you have your mechanic check the brakes. If you hear that shrieking sound signaling brake trouble, point out the problem so your kids can learn from the lurching.

When you stop for gas, have your children clean the windows and show them how to check the tire pressure. Soon they’ll be reminding you when these basics need attention. You should also have them go through a checklist to make sure you have on hand maps, an emergency flare, a first-aid kit, extra water, and some simple tools.

Car maintenance helps prevent car trouble—the unexpected kind that could leave your kids stranded on the side of the road or in an accident. It’s one more way you can help your kids stay safe. And imagine what all that car information will be worth to them when they get their own wheels. Believe it—they’ll thank you later.
