You're jumping the gun a bit, no?

With the engine cold and off get your manual out and find the hood release, locate the oil dipstick, oil filler cap and coolant reservoir. With the hood open, rag in hand, pull the dipstick out and check the level on the stick. It should be in the range shown in the manual. Somewhere on the flat part of the stick, prefferably 1/2 or above. Add oil in the recommended weight a little at a time until you get it up to the upper mark.

As far as coolant, look at your expansion tank on the fender. There's a min and max mark embossed on the tank. Coolant should be somewhere between the two. If it's low, add the approved type in a 50/50 mix with distilled water.

Close the hood. Get in the car and reset your trip meter. If you are losing or burning oil you can get an idea about how much by checking it weekly and noting the mileage on the trip meter when you reach say, the halfway point on the stick. Same for the coolant.

The manual makes good reading and will instruct you on the owner service items you should be checking weekly or monthly. Oil, coolant, trans fluid, power steering fluid, brake fluid, tire pressure etc. Ignore this stuff and you'll be walking at best or paying a serious repair bill at worst.

Good luck,
