2015? First don't wax or clay it any time soon, not only doesn't it need it, you could ruin the clear coat - often why you see "swirls" in a lot of unpolished paints, someone was too rough with it in the past and now it needs polishes to fill it in. In my experience, a well-maintained car doesn't need waxed for 3 years, and doesn't need polished for 5, because once you start that process, the paint/finish always needs it again. Wash it as it gets dirty, there's nothing else to do with a new car.
You could use some kind of spray on wax or something, but whatever it is don't do a lot of wiping no matter what. A soap with built-in "sealant/wax/protectant" will get you the nice beaded water or runoff you expect.
Take off thick road dirt, grime, goo, etc. first, and when it is that dirty, use two buckets, one with soapy water, one to rinse the mitt, to prevent transferring around little pieces of dirt. Bird droppings and such, soak them, and wipe them off gently and in short wipes, don't push it in circles.
Wash from top to bottom. I always spray off the entire body, then soap and rinse the roof, then soap and rinse windows, then soap and rinse front to back, always rinsing off the soap in patches so it doesn't dry on the car anywhere. And it helps to keep everything sprayed so it's still wet when you go to dry it, preventing spots.
Again, no need to rub really hard or go over and over an area, be gentle with it. With the rights soaps and cleaners it's should be pretty easy. I use a lot of Griot's products now, they're pricier but I like them. Remember to wipe out the door wells, and door frames, and trunk and under the hood for an actually detailed final product.
As for interior, basically the same idea. Try not to polish the dash unless you like a lot of reflection in your face when driving. I try to go for clean inside, not shiny. Again, not much needs "cleaned" if you are generally pretty neat and tidy in the car. Twice a year, or pre- and post-winter if you're in that kind of climate, you can use a leather conditioner, light, not heavy, to wipe the seats down and clean them, not shine them up. Also use a "dressing" or similar cleaner on all of the door and trunk seals to keep them moist, usually the same as tire dressing will do.
You could check tire pressure, fluids, and so on weekly if you want to be a fanatic, but once a month would be safe. If you're high mileage, or simply a fanatic, you could keep a log of things as well, to see if anything odd or unusual is occurring over the miles. Also as it's new, use the same schedule just to check all the power equipment you may not normally be using, all the windows work, the sunroof works, etc. so maybe you catch something before it is a problem, and still under warranty.
