Roll Bar warning lights remain on.
2009 SL600
After making an accelerated U Turn to make the traffic light, my roll bar red warning light came on as did the roll bar icon light. If I raise the roll bar the red light warning goes out but the icon remains lit. If I lower the roll bar the red light warnings come back on to raise the roll bar.
I tried turning the car off for a few minutes but the problem persist when I turn it back on. Same if I lower the roof then back up.
Is there a reset on the roll bar warning lights and Icon?
I can get rid of the red warning information temporarily with the speed odometer reset but it return after restarting the car.

Just a wild *** guess at a follow up question: do your windshield wipers work properly? The reason I ask ... I had a similar problem with the rollbar alert when my EIS failed. In any event, I agree with Rudeney about needing SDS analysis. Good luck. Let us know how you get this sorted.

Same problem
I know this is very old tread but i have exactly same problem on sl350 2009. When I used to check code it says b66 tilting cone sensor

The tilt cone is internal in the roof control (RVC). Not a very common problem, but you probably need to replace the module.
