HOW DOES THE AUTOMOBILES DANGEL 4X4 EQUIPMENT WORK -> Operating principle for Your Fiat Scudo Van Second Generation (2007-2016)

According to the version, the system uses two running positions:  
a 2WD (eco) position where traction comes from the two front wheels only  
(green lights on).  
a 4WD (auto) position for optimum traction from all four wheels depending on  
the road surface (green + yellow lights on).  
Note:  
Since the jaw clutching system is mechanical, the light display does not  
necessarily represent the mechanical position of the jaw clutch (see  
transition mode in the chapter on sound and light signals).  
Never shift from 2WD to 4WD position when the front wheels are  
slipping.

The operation of the 4 wheel drive system designed and constructed by Automobiles  
DANGEL is based on automatic and optimum distribution of the engine torque  
with the coupler at the heart of the system.  
Depending on the grip of the front axle wheels, the coupler automatically distributes  
engine torque to the rear axle wheels, thus giving the vehicle increased  
driveability.
