Those are the lower gears. You car is an automatic and will shift gears on it's own. Lets say you are going down a very steep hill. you do not want to ride the brakes all the way down so you can shift down manually to the lower gears and let the engine brake for you to prevent you from burning up your brakes.

Different manufacturers label them different ways, but in general, with an automatic, putting it in either D or D3 allows it to shift through the gears 1, 2, and 3 (or however many it may have, as there are some that have up to 7 or 8, now) automatically as it is needed. That is up and down through the gears. When you put it in 1, or 2, or whatever, it generally does NOT automatically shift, but stays in whatever gear you put it in. A lot of automatics have what is called Overdrive, which is sort of like a whole 'nother gear. Putting it in 3, or 2, for instance, will not allow it to go into Overdrive. It gives you higher engine revolutions and lower gas mileage. In a generic sense, it is almost always just better to put it in D (or whatever your model calls it) and let it do the work. The other answer is absolutely correct, though; as you go down a long, steep hill, you use the lower gears to allow the engine to slow the car down without you using the brakes. That advice was to keep the brakes from overheating, but modern disc brakes don't do a lot of overheating, and generally that is no longer a problem. Wait until you drive a hybrid: it has NO gears, using a Constant Velocity Transmission and never shifts. Pretty cool.































Hope that this answered your question.
