Problems with the transmission
Transfer case
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.
Because ESP® is an automatic system, the engine and ignition must be switched off (SmartKey in position 0 or 1 or Start/ Stop button in position 0 or 1) when the electric parking brake is being tested on a brake dynamometer (maximum 10 seconds).
Braking triggered automatically by ESP® may seriously damage the brake system.
Vehicles with 4MATIC must not be towed with either the front or the rear axle raised, as doing so will damage the transmission.
This section is only valid for vehicles with 4- wheel drive (4MATIC). Power is always transmitted to both axles.
