It is part of the active safety system where the car's safety system prepares for a potential crash by, in some cases, closing windows, sunroof, pre-tensioning seat belts etc.

Ideally get the fault code(s) read by someone experienced with Star.
 
Mine did that. I turned it off and on again. They did a software update later that claims to fix it.
 
just started the car again and when i am in drive it runs like it s in 2 gear . i tried seats,windows sunroof everiting is working fine. i whent to a local garage did a diagnose and the bloke told me that there is nothing on sistem but i may need to fix the gearbox . i am confuze now . thanks for all your respons

If it is stuck in second gear it is operating in limp home mode. It needs a proper diagnostic with Star, a generic OBD scanner (as probably used by the "bloke" in the garage) cannot interrogate all of the electronic systems and subsystems.
 
Have you tried lock to locking your steering wheel?
Along with ABS,BAS etc, the pre-safe warning is one of those cleared by re-setting the steering.
My S55 has the same problem, with all the other warnings, but thats down to a faulty speed sensor on the drivers side front wheel.
It also causes the steering to tighten as well.
