and traffic conditions permit. Always pay full
attention to traffic conditions first before
operating system controls while driving.

ing a distance of 44 feet (approximately
14 m) every second.

may be impaired.
This condition might seriously impair the
operating safety of your vehicle.
We recommend that you have any service
work on electronic components carried out
by an authorized Mercedes-Benz Center.
