What Is This ?

Anyone happen to know what this is? It's low of fluid but I'm not sure what type of fluid it needs. This is the M278 engine on a 2013 S550.

Power Steering Perhaps?

Thats the Power Steering Fluid Reservoir

Uses Pentosin CHF 11S Fluid.

Every 2 Years i suck out as much as i can and fill it with new fluid. Then start the engine and go lock to lock a few times and then check the level

Good luck.

Turn the steering wheel all the way left and then right a few times
