Make sure all fluids are full.
You can also add oil up to the full and antifreeze and that helps freshen them up.
There are two areas that are frequenly low, despite you thinking, no it's just been from the dealer or a car enthusiast so it will be fine.
That's the intercooler antifreeze level. Member Hammdo has hard to find instructions using a 1" diameter clear hose, 1' long. Stick it in the intercooler fill port and keep 1/4 full. Simply refill it so as the level goes up and down 6" when the pump kicks in, the system will still burp itself and not run all over like if you don't have a hose extension sticking up or the cap on. I did it the harder way and
kept filling it to near the top and
close the cap and let the intercooler pump run turning the car on and off until it got all filled up.

The other area is many cars are low on trans fluid. If you pull a plug you think is correct it'll drain fluid and will be low. I posted manual pages on how to correctly check it.
