The Mercedes W124 with 4Matic allwheel drive system is implemented in a mechanical transfer case, in which the connection of the hydraulic drives occur ZHM liquid supplied under high pressure.

Start the movement always happens with the distribution of effort 35% on the front axle and 65% on the rear axle. These proportions are saved to a speed of 20km / h (if the movement was the beginning of the acceleration is greater than 0.5m / s, the frontwheel drive is switched on, provided that the rate of acceleration). Then the frontwheel drive is switched off, and the movement continues only on the rear wheel drive. If the difference in wheel speed is more than 2 km / h to a speed of 100km / h or more than 2% in excess of 100km / h, then reconnects the front drive with a moment 35/65%, and remains on for approximately one second after the wheel speed equalized.

In that case after the 35/65% speed of the wheels is not equalized, the center differential lock is switched on, i.e. the time allocated for 50/50%. If in this case the vehicle speed is less than 38km / h, in addition to all the locked rear crossaxle differential. Lock in the 4Matic rear axle can only be activated to 38km / h.
