Transfer case
The vehicle is equipped with all-wheel drive
(4MATIC). Both the front and rear axles are
powered at all times when the vehicle is being
operated.

tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized
Mercedes-Benz Center. You could
otherwise seriously damage the brake
system or the transfer case which is not
covered by the Mercedes-Benz Limited
Warranty.

button in position 0 or 1) when the parking
brake is being tested on a brake test
dynamometer. Such testing should be no
longer than 10 seconds.

conditions must always be his/her primary
focus when driving.

it to be done safely.

(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
The control system relays information to the
multifunction display. Multifunction steering wheel
