Electronic D D ifferential L L ock ( ( EDL)*
Vehicles with anti-lock brakes (ABS)* can
also be equipped with an electronic dif-
ferential lock.
The EDL makes it much easier, or even
possible, to pull away, accelerate and
climb steep gradiants in unfavourable
conditions.
The EDL works fully automatically – the
driver does not need to do anything at all.
It uses the ABS* sensors to monitor the
speed of the driving wheels. Up to a
speed of about 40 km/h (25 mph), a dif-
ference in speed of the drive wheels of
approximately 100 rpm caused by a slip-
pery road surface on one s s ide is balanced
out by slowing down the wheel which is
slipping and thereby applying more dri-
ving force to the other drive wheel
through the differential.

–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
To ensure that the brake disc of the
braked wheel does not overheat, the EDL
will automatically switch itself off if exces-
sive demands are placed on it. The vehi-
cle remains operational and has the same
characteristics as a vehicle without EDL.
For this reason, the switching off of the
EDL is not noticed.
As soon as the brakes have cooled off, the
EDL will switch itself back on again.
If the ABS* warning lamp lights up there
may be a fault present in the EDL. Contact
a Technical Service Centre as soon as pos-
sible.
