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 lime 4WD" (center differential system). This allows you to optimally distribute the torque between the wheels, but when slipping, a situation is possible when the torque will be transmitted only to 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) Most 4WD vehicles are equipped with an automatic center differential lock system (viscous coupling). This system does not require the intervention of the driver, but does not provide 100% blocking and the clutch is activated with a slight time delay.
Scheme of all-wheel drive with a viscous coupling. 1 - front axle differential, 2 - axle differential, 3 - viscous coupling.
- 2) Models with automatic transmission are equipped with an automatic locking center differential "C. DIF. AUTO'.
When you press the button on the instrument panel, the indicator lights up (C. DIF. AUTO) and the system automatically locks the center differential depending on road conditions.
Indicator location "C. DIF. AUTO".
Under normal operating conditions, the automatic locking center differential "C. DIF. AUTO" should be included (the button on the instrument panel is pressed, the indicator on the instrument cluster is on).
System of automatic blocking of interaxal differential 'С. DIF. AUTO" should be turned off (the button on the instrument panel is not pressed, the indicator on the instrument cluster does not light up) under the following conditions;
- Replacing one of the car's wheels with a spare "dokatnoe" smaller diameter wheel
- Car being towed by another vehicle.
