-The integral start ing ass ist helps you when
driving by automatically releasing the park­
ing brake
c> page 79, Starting from rest .
- When start ing o n inclines, the starting as­
sist prevents the vehicle from unintentional­
ly rolling back. The braking force of the
pa rking brake is not released until suffic ient
driving force has been bui lt up at the
wheels.

82 On the road
-For reasons of safety, cruise contro l
should not be used in the city, in stop­
and-go traff ic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
planing) - risk of accident .
- Turn off the cruise control temporar ily
when ente ring turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "rest ing"
yo ur foot on the accelerator peda l causes
the cruise control not to brake. This is
because the cr uise con trol is overridden
by the d river 's acce lerat ion.
- If a bra ke system malfunction such as
overheat ing occurs when the cru ise con­
tro l system is sw itched on, the braking
function in the system may be switched

Transmission S tronic
Introduction
The automat ic transm iss ion is controlled elec­
tronically. The transmiss ion upshifts or down­
shifts automatically depend ing on which drive
p rogram is se lected.
When a
moderate driving sty le is used, the
transmission selects the most econom ica l
d riving mode.
It w ill then change up early and
de lay the downshifts to g ive better f uel econ ­
omy .
The transmis sion swi tches to a sporty mode
after a k ick-down or when the dr iver uses a
sporty driving sty le characterized by quick ac­
celerator peda l movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the drive r can a lso se lect the gears
manually ( tiptronic mode ) ~ page 87.
The S tronic is a dual-clut ch tra nsmission.
P ower is transfe rred using two clutches that
work independently from one another . They
rep lace the torq ue converter used in conven­
tional automatic transmiss ions and allow the
vehicle to accelerate without a noticeable in­
terruption in traction.

86 Transmission
-Unintended vehicle movement can cause
serious injury .
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running,
activate the parking brake and move the
selector lever to P .
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the
engine is running.
- Never shift into
R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases
braking distance or causes complete fail­
ure of the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake .
- Never hold the vehicle on an incline with
a slipping clutch . The clutch opens auto­
matically when it becomes too hot from
the overload . An indicator lamp
l'§J illu­
minates and a driver message appears
Q page 88 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
Q page 195. Otherwise, any increase in
engine speed may set the vehicle in mo- tion
, even with the parking brake ap­
plied.
@ Note
- When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear is selected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake
pedal to prevent the vehicle from rolling .
- Allowing the vehicle to roll when the en­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv­
er's safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
Hill descent control is activated when these ­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de ­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations. It may st ill be nec­
essary to adjust the speed with the brakes.
Hill descent control switches off once the de­
cline levels out or you press the accelerator
pedal.
On vehicles with the cruise control system*
Q page 81 , hill descent control is also activat­
ed when the speed is set.
A WARNING -
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
