Transfer case
This section is only valid for vehicles with 4- wheel drive (4MATIC). Power is always transmitted to both axles.
Performance tests may only be carried
out on a 2-axle dynamometer. The brake
system or transfer case could otherwise be
damaged. Contact a qualified specialist
workshop for a performance test.
Mercedes-Benz recommends that you use
an authorized Mercedes-Benz Center for
this purpose.
To prevent ESP® from intervening, the
ignition must be switched off (SmartKey or
the Start/Stop button in position 0 or 1) if:
• the electric parking brake is being tested
on a brake dynamometer.
• the vehicle is being towed with only one
axle raised (not permitted for vehicles
with 4MATIC).
The brake system could otherwise be damaged.
