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.

In free position, the Dangel rear axle distributes the torque symmetrically between  
the right wheel and the left wheel. Moreover, the differential allows the right rear  
wheel and the left rear wheel to turn at different speeds. In bends, this guarantees a  
robust drive performance, and preserves the transmission and tyres.  
In the locked position, the Dangel rear axle drives the rear wheels at the same  
speed, and makes optimum use of the tyre grip. This allows the vehicle to be driven  
on the most difficult ground : cross axle situations, bumpy, steeprises…  
. IMPORTANT  
The use of the rear differential locking must remain exceptional.  
- The rear differential locking system must only be actived on ground with poor  
grip.  
- Do not use the locking system on ground with high adhesion, particulary in  
bends.  
- Do not engage the locking when the wheels are spinnnig.  
- Engage the clutch gently when restarting for the first time.  
- Unlock the differential once you have crossed the difficult zone.  
Use of the rear differential locking (option)  
The rear axle with differential locking increases your vehicle's cross-country  
capabilities.  
Steep bumpy or slippery slopes and cross axle situations can be tackled when the  
rear differential is locked.  
We advise you to lock the rear differential before embarking on the difficult zone.  
On a slope or on ground with variable adhesion, proceed gradually so as not to  
provoke jerking in the transmission. In fact, in this configuration and depending on  
the nature of the ground, it can happen that all the drive effort is taken over by the  
only rear wheel which still has some grip.  
Do not do U-turns on slopes and ways remain in the line of the greatest slope.

WARNING :  
For you safety to guarantee durable use of your vehicle, do not abuse the  
crossing capabilities, this is not an all-terrain vehicle.  
. How to lock the rear differential  
When stopped or at slow speed, turn the nob 1/4 turn clock-wise to lock the rear  
differential. The nob will automatically return to the centre.  
After rotating the nob, the axle indicator will start blinking (+ quick intermittent sound  
signal) until the axle is actualy locked and then stays lit to confirm that the locking is  
complete. A buzzer sounds when the differential is actually locked (slow intermittent  
sound signal).  
Control nob (according to  
the version)  
Dashboard compartiment  
Indicator  
light  
For your safety, the system prevents locking the differential at speeds over  
approximately 30 km/h.  
. To unlock the rear differential  
Turn the nob again 1/4 turn clock-wise to unlock the rear differential.  
Note:  
- Unlocking is automatic when the speed exceeds 30 km/h, and after turning off  
the engine.  
- When stopped, unlocking may not be instantaneous. It is signalled by blinking  
light. Should this happen, just drive for a few meters to unlock the differential.

. Sound and light signals  
Under normal operation:  
- The orange indicator stays lit continuously to confirm the locking.  
- A buzzer is heard when the differential is actually locked (slow intermittent  
sound signal).  
In transition mode: (locking asked but not mechanically engaged).  
- The orange indicator blinks and the sound signal is intermittent and rapid.  
WARNING  
For your safety and to preserve your vehicle: Since the locking system is a  
mechanical system, the transition phase may be longer or shorter.  
If the system remains in transition mode, please contact your certified repairer.  
The electrical circuit fuse for rear axle lock is placed behind the ashtray.  
Fuse: 10 amperes.

Note:  
The electrical connection is made on the cigarette lighter power supply. In case the  
rear locking does not work, check the cigarette lighter's fuse by referring to the  
manufacturer's maintenance manual

The hydraulic coupler  
Permanently active, it detects the loss of grip of the front wheels and then transmits  
the engine torque to the rear wheels.  
The coupler will adjust the percentage of torque as required.

. Rear axle with differential  
The differential, a mechanical assembly mounted in the rear axle, allows the same  
wheels on one axle to turn at different speeds (absolute necessity in bends to avoid  
tyre scrub). It also multiplies the torque.  
As an option, the rear differential can be lockable. Locking the rear differential  
increases your vehicle's cross-country capabilities, but must be used with care.  
. Lateral transmissions (or cardan)  
They transmit the engine torque from the differential to the wheels.
