Driving
Electronic differential lock (EDS)* The EDL operates along with the ABS in vehi-
cles equipped with El
ectr
onic Stability Con-
trol (ESC)*.
EDL helps the vehicle to start moving, accel-
erate and climb a gradient in slippery condi-
tions where this may otherwise be difficult or
even impossible.
It uses the ABS sensors to monitor the speed
of the driven wheels.
At speeds of up to approximately 80 km/h
(50 mph), it is able to balance out differences
in the speed of the driven wheels of approxi-
mately 100 rpm/min caused by a partially
slippery road surface. It does this by braking
the wheel which has lost traction and distrib-
uting more driving force to the other driven
wheel via the differential.
To prevent the disc brake of the braking
wheel from overheating, the EDL cuts out au-
tomatically if subjected to excessive loads.
The vehicle will continue to function normally
without EDL. For this reason, the driver is not
informed that the EDL has been switched off.
The EDL will switch on again automatically
when the brake has cooled down. Control lamp
A malfunction in the EDL is indicated by the
ESC contr ol l
amp . Take the vehicle to a

speed. The upshift t
o the next higher gear is
delayed until the engine reaches maximum
rpm. WARNING
Please note that if the road surface is slip-
pery or wet, the kick -do
wn feature could
cause the driving wheels to spin, which
could result in skidding. Launch control program
Valid f
or vehicles: with Launch-Control/6-
Speed DSG with diesel engines superior t
o 125
kW and petrol engines superior to 140 kW.
The Launch control programme enables
maximum acceleration.
Condition: the engine must have reached op-
erating temperature and the steering wheel
must not be turned.
The engine speed for launch-control is differ-
ent on petrol and diesel engines. To use the
launch-control you must disconnect the anti-
slip regulation (ASR) through the Easy Con-
nect system menu
