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.
! Only conduct operational or performance
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.
®
! Because the ESP operates
automatically, the engine and ignition must
be shut off (SmartKey in starter switch
position 0 or 1 or KEYLESS-GO start/stop
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.
Active braking action through the ESP
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
