Transfer case
This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always trans-
mitted 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.
!
Since ESP
®
engages automatically, the igni-
tion must be switched off (the SmartKey or
Start/Stop button must be in position 0 or 1)
if:
R
the electric parking brake is being tested
on a brake dynamometer
R
the vehicle is being towed with only one
axle raised (not permitted for vehicles with
4MATIC).
The brake system could otherwise be dam-
aged.
!
Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised, as
doing so will damage the transmission.
