"Last year we removed over 600 functions from our cars - functions that no one really needed and no one knew how to use," said Stephan Wolfsried, who is responsible for electronic engineering at the group.
"It is our aim to focus on things that make sense," Wolfsried said. "We will no longer offer drivers everything that is adjustable, just because it can be adjusted."
Wolfsried said that one example of an unnecessary feature is the individual memory setting for auto seats within a car key.
Wolfsried expects that the number of adjustable extras on cars will continue to decrease.
Because of a large number of electronically linked components, Mercedes vehicles had a lot of breakdowns in 2003.
Said Wolfsried: "Our clear demand for Mercedes-Benz products is zero error."
