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 in position 0 or 1) if:
- the 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.
