How do you move the steering wheel on a 1998 C230 Mercedes like going up or down or high and low?

There are two small access holes on the backside of the steering wheel. They are a torx head, remove these screws (screws will stay inside of steering wheel, but must be loosened all the way) then pop the airbag off. You then will have a big Allen head nut holding the steering wheel on the steering shaft. Remove the nut and the steering wheel comes off.

AnswerAnd if you actually did mean -move wheel- rather than -remove wheel - not all the cars have a moveable steering wheel. As I recall, it was an option to have one that fully tilted and some packages only came with a height adjustable one. In both cases there is a lever near or along the steering column that allows the adjustment.
