Apparently, that ESP button doesn't turn off all of the safety features on our cars. This document tells how to do it for new Mercedes in general terms, but our SLKs do not have some of the features described here (buttons on steering wheel, etc). Does anyone know the sequence for our cars? I did a search before posting, but found no information.
