Attention: To avoid damage to the transmission components, 4WD models are not allowed to be towed using the partial load method (lifting only one of the vehicle axles).
4WD vehicles have permanent all-wheel drive, the so-called "Full time 4WD" (center differential system). This allows you to optimally distribute torque between the wheels, but when slipping, it is possible that the torque will be transmitted to only one wheel that has the least grip. To prevent this situation, a center differential lock is designed.
Depending on the configuration, blocking can be carried out in two ways:
1) With mechanical locking center differential (C. DIF. AUTO). When you press a button on the instrument panel, the hydraulic drive located on the transfer case blocks the center differential at the command of the electronic control unit. This leads to the necessary distribution of torque to 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 actuated with a small time delay.
All-wheel drive scheme:
1 - cross-axle differential,
2 - center differential,
3 - viscous coupling.
