The German website Pitwalk.de thinks so and suggests that the Mercedes car uses hydraulic shock absorbers to gain speed, both on the sides and on the third element in the middle of the car, in the transmission. The hydraulics work via small valves in the dampers that let the hydraulic oil through in different volume flows. If you manage to influence the opening and closing times of these valves, you can virtually pull the dampers down. This allows the whole car to be lowered, reducing drag on the straights and increasing top speeds.

Therefore, to make it legal in Formula 1, the driver himself needs to make a command. If Pitwalk.de is right and Mercedes really does have this on the car, Hamilton will need to actively do something and this could be the forward and backwards movement on the steering wheel.
Footage of the steering wheel being possibly moved 'back n forth' during Quali in Brazil is highlighted in a video clip below titled
'Lewis using DAS System during Qualy Lap steering wheel moves'. So Are Merc able to manipulate the ride height this way????
