3. INFORMATION ABOUT THE
ALL-WHEEL-DRIVE SYSTEM
If the traction reduces on one axle, a locking torque is generated in the centre differential
and the forces are directed to the axles with the better frictional values in this particular
situation. Up to 60% of the drive power can be directed to the front axle and up to 78% can
be directed to the rear axle.

3.3 EDL function (electronic differential lock)
The vehicle is equipped with an additional EDL function (electronic differential lock using
braking intervention). A self-locking centre differential must not be compared to a mechan-
ical 100% differential lock. If a wheel starts to slip there is no drive until the EDL function
activates.
The EDL regulator actuates only at a defined speed difference between the axles/wheels,
that is to say that you have to accelerate appropriately until EDL regulator generates a
support torque via a braking intervention.
This support torque is then available to the opposite wheel as a drive torque. The self-lock-
ing centre differential supports the EDL regulator insofar as the brake torque, reinforced
according to the locking value, is directed to the other axle.
The EDL function switches off automatically under excessive loading to prevent the brake
on the braked wheel from overheating. The vehicle remains operational. The EDL function
switches on again automatically once the brake has cooled down.
