The ATF fluid has to be checked with every service ie every 15,000km. Coolant has to be added at a ration of 70%water to 30% coolant to the radiator. After learning this to my detriment (car out of warranty and didn't even know about ATF fluid needing to be topped up or changed, thanks to mechanic for not knowing either or failing to mention it). I am not even using MB approved oils, but Ravenol products instead, which are 100% synthetic and therefore the correct thing to use for a CVT gearbox. Hope this helps a bit.
