Start and driving
Electronic differential lock (EDS)* The EDL operates along with the ABS in vehi-
cles equipped with Electronic St
abilit
y 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 control lamp
. Take the vehicle to a
specialised workshop as soon as possible. WARNING

Driving
The system maintains brake pressure for ap-
pr o
ximat ely tw
o seconds aft
er the driver
takes his foot off the brake pedal to prevent
the vehicle from lurching backward when it is
started. During these 2 seconds, the driver
has enough time to release the clutch pedal
and accelerate without the vehicle moving
and without having to use the handbrake,
making start-up easier, more comfortable
and safer.
These are the basic operation conditions:

Automatic gearbox/DSG au-

Intr oduction Your vehicle is equipped with an electronical-
ly controlled manual gearbox. T
or
que be-
tween the engine and the gearbox is trans-
mitted via two independent clutches. They
replace the torque converter found on con-
ventional automatic gearboxes and allow for
smooth, uninterrupted acceleration of the ve-
hicle.
The tiptronic system allows the driver to
change gears manually if desired

throttle, the gearbox will shift down to a lower
gear , depending on r
oad speed and engine
speed. The upshift t o the ne
xt higher gear is
del
ayed until the engine reaches maximum
rpm. WARNING
Please note that if the road surface is slip-
pery or wet, the kick-down f eat
ure could
cause the driving wheels to spin, which
could result in skidding. Launch control program
Valid for vehicles: with Launch-Control/6-
Speed DSG with diesel engines superior to 125
kW and petr
ol engines superior t
o 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

Start and driving
Downhill speed control* The downhill speed control function helps the
driver when driving down steep gr
adients.
Do
wnhill speed control is activated when the
selector lever is in D/S and the driver applies
the foot brake. The automatic gearbox auto-
matically engages a lower gear that is suita-
ble for the slope. The downhill speed control
function attempts to maintain the speed at
which the vehicle was travelling when the
foot brake was applied (subject to the laws of
physics and technical drive limitations). It
may be necessary to adjust the speed again
using the foot brake in certain situations. Giv-
en that the downhill speed control can only
change down to 3rd gear, on very steep de-
scents the tiptronic mode may be required. In
this case, manually reduce the tiptronic to
2nd or 1st gear to use the engine brake and
reduce the charge on the brakes.
Downhill speed control is deactivated as
soon as the road levels out again or you press
the accelerator pedal.
