Note: For more information about the operation of the systems, see the chapter "Manual".
Depending on the configuration, blocking can be carried out in two ways:
1) Mechanical locking of the center differential (C. DIF. LOCK). When you press the button on the instrument panel, the pneumatic drive located on the transfer case, "hard" blocks the center differential. This leads to an equal distribution of torque on the front and rear axles, which significantly improves cross-country ability.
2) Automatic locking center differential (viscous coupling). This system does not require driver intervention, but cars equipped with this system have worse off-road performance compared to cars with the system "C. DIF. LOCK". This is due to the fact that the viscous clutch does not provide 100% blocking and the clutch is actuated with a small time delay.
