4WD vehicles have permanent all-wheel drive, the so-called "Full time 4WD", with locking center differential.
Application: for more detailed information about the operation of the systems, see chapter "Manual".
Depending on the configuration, blocking can be carried out in two ways:
1. With a system of mechanical locking of the center differential (C. DIF. AUTO). When you press a button on the instrument panel, the center differential locks. This leads to an equal distribution of torque on the front and rear axles, which significantly improves cross-country ability.
2. With automatic locking center differential (viscous coupling). This system does not require driver intervention, but vehicles equipped with this system have poorer off-road capability compared to vehicles with the system "C. DIF. AUTO". This is due to the fact that the viscous clutch does not provide 100% blocking, and the clutch is activated with a small time delay.
