If you're planning on doing some work underneath your car, it's important to know how to safely support it using a jack and jack stands. First, find the correct jacking point for your vehicle- there should be a sticker or embossed mark that indicates where it is. Once you've found the jacking point, place the jack underneath and raise the car until the tire is just off the ground. Next, put a jack stand under each end of the car (one at each jacking point), then lower the car onto the stands. Now your car is securely supported and you can work underneath it without worry!
