b rake provides var ious convenience and safety
f u nctions.
When start ing f rom rest
- The integral starting assist helps you when
driv ing by automat ically releasing the parking
brake ¢
page 78, Starting from rest.
-When sta rting on inclines , the starting assist
prevents the vehicle from un intent ionally roll­
ing back. The bra kin g for ce of the par kin g b rake

When stopping at a traffic signal or stopp ing in
city traffic on vehicles with an automatic trans­
miss ion, the park ing brake can be applied . T he
vehicle does not have to be held with the foot ­
brake. The parking brak e eliminates the tendency
to creep with a drive range engaged . As soon as
you dr ive off as usual , the parking brake is re­
leased automatically and the veh icle starts to
move.
Starting on sl opes
When starting on inclines, the star ting ass ist pre­
vents the vehicle from unintentionally rolling back. The braking force of the parking brake is
not released until sufficient driv ing force has
been b uilt up at the whee ls .
(D Tips
For safety reasons, the park ing brake is re­
leased automatically only when the dr iver's
safety belt is engaged in the buckle.
Starting off w ith a trailer
T o prevent rolling back unintentionally on an in­
cline, do the following:
.,. Keep the switch@q page 77, fig . 92 pulled
and depress the accelerator . The park ing b rake
stays applied and prevents the vehicle from
ro lling bac kward .
.. You can release the switc h @ once you are su re
t h at you a re developing enough driving force at
the whee ls by depressing the acce lerator .
D epending on the weight o f the r ig (veh icle and
trai ler) and the seve rity of the in cli ne, you may
roll backwards as you sta rt. Yo u can prevent roll ­
i n g bac kwards by ho lding the parking brake
switch @ pulled out and acce lerating -just as
you would when starting on a hill with a conven ­
tional hand brake .
Driving
Emergency braking
In the event that the conventional brake system
fails or locks .
.. In an emergency, pull the sw itch @ q page 77,
fig . 92 and continue to pull it to slow your vehi­
cle down with the parking brake .
.. As soon as you release the switch @ or accele r-
ate, the b ra ki ng process stops.
If you pull the switch @and hold it above a
speed of about 5 mph (8 km/h), the emergency braking function is i nitiated . The vehicle is b raked
at all fo ur whee ls by act ivati ng the hydrau lic
brake system. The br ake performan ce is s imi la r
to maki ng a n emergency stop
q &. .
In order not to act ivate the eme rgency braking by
mis take, an aud ib le warn ing tone (buz ze r)
sounds when the swi tc h @ is p ulled. As soon as
the switch @ is re lease d, or the acce le rator pedal
is depressed, emergency braking stops.
A WARNING
=
Emergency braking should on ly be used in an
emergency, when the norma l foot brake has
failed or the brake peda l is obstructed. Us ing
the parking brake to perfo rm emergency brak­
ing will slow your vehicle down as if you had
made a full bra ke application . T he laws of
physics cannot be suspended ev en with ESC
and its a ssociated components (A BS, ASR,
E DS). In co rners and when road o r we ather
conditions are ba d, a f ull brake applica tion
can cause the ve hicl e to skid o r the rear end to
b reak away -risking an accident.
Speed warning system
Overview
The speed warning sys tem helps you to keep your
driving speed below a set speed limit.
The speed warn ing system warns if the driver ex­
ceeds a previous ly s tored maximum speed. A
warning tone will sound as soon as the veh icle
speed exceeds the set speed by about 3 mph

power or through an active brake intervention.
A WARNING
-Always pay attention to the traffic around
you when the cruise control is in operation.
You are always responsible for your speed and the distance between your vehicle and
other vehicles.
Driving
- For reasons of safety , cruise control should
not be used in the city, in stop-and-go traf­
fic, on twisting roads and when road condi­
tions are poor (such as ice, fog, gravel, heavy ra in and hydroplaning) - risk of acci­
dent .
- Turn off the cruise control temporarily when entering turn lanes , highway exit lanes or in
construction zones.
- Please note that inadvertently "resting" your foot on the accelerator pedal causes
the cruise control not to brake. This is be­
cause the cr uise control is overridden by the
driver's accele rat ion.
- If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is switched on, the braking function in
the system may be switched off . The other
cruise control functions remain active as
long as the ind icator
light til;rnM4 (US mod­
els)

sired speed is displayed.
You can also press the accelerator pedal down to increase your speed, e.g . if you want to pass
someone . The speed you saved earlier will re­
sume as soon as you let off of the accelerator
pedal.
If, however, you exceed your saved speed by

Automatic transmission
multitronic, S tronic,
tiptronic
Introduction
Appl ies to vehicles: with multitronic/5 tronic/tiptronic
The automatic transmission is controlled elec­
tronically. The transmission upshifts or down­
shifts automatically depending on which drive
program is se lected.
When a
moderate driving style is used, the
transmission selects the most economica l driving
mode. It will then change up early and delay the
downshifts to give better fuel economy .
The transmission switches to a sporty mode after
a kick-down or when the driver uses a
sporty driv­
ing style
characterized by quick accelerator pedal
movements, heavy acceleration, frequent
changes in speed and traveling at the maximum
speed .
If desired, the driver can also se lect the gears
manually (tiptronic mode) q page 83.
Various automatic transmissions may be instal­
led, depending on the model:
multitronic transmission
The multitronic transmission is a continuously
variable transmission. Power is transferred using
a mu ltidisk clutch. In contrast to conventional
automatic transmissions using shifting opera­
tions, the transmission ratio in the continuously
variable transmission is changed continuous ly.
This optimi zes the comfort level and conserves
fuel.
S tronic transmission
The 5 tronic is a dual-clutch transmission. Power
is transferred using two clutches that work inde­
pendently from one another. They replace the
torque converter used in conventional automatic
transmissions and allow the vehicle to accelerate
without a noticeable interruption in traction .
tiptronic transmission
In the tiptronic transmission, power is transfer­
red by a torque converter.

cluster display.
P -Park
In this se lector lever position the transmission is
mechanically locked . Engage P only when the ve­
hicle is
completely stopped~.&. in Driving the
automatic transmission on page 86.
To shift in or out of posit ion P, you must first
press and hold the brake pedal and then press
the release button in the selector leve r handle
whi le moving the selector lever to or from P. You
can shift out of this position only with the igni­
tion on.

Automatic transmission
When the vehicle is stationary or at speeds below
1 mph (2 km/h), you must always apply the foot­
brake before and while moving the lever out of N.
DIS -Normal position for driving forward
In the D/S position, the transmission can be oper­
ated either in the normal mode Dor in the sport
mode S . To select the sport mode S, pull these­
lector lever back brief ly. Pulling the lever back
again will se lect the normal mode D . The inst ru­
ment cluster display shows the selected driving
mode.
In the
normal mode D , the transmission auto­
matically selects the suitable gear ratio . It de­
pends on engine load, vehicle speed and driving
style.
Select the
sport mode S for sporty driving. The
vehicle makes full use of the engine 's power .
Shifting may become noticeable when accelerat­
ing.
When the vehicle is stationary or at speeds below 1 mph (2 km/h), you must a lways apply the foot
brake before and while moving the lever to D/S
out of N.
A WARNING
Read and follow all WARNINGS¢.&. in Driv­
ing the automatic transmission on
page 86.
(D Note
Coast ing downh ill with the transmission in N
and the engine not running will result in dam­
age to the automatic transmission and possi­
bly the catalytic converter.
@ Tips
- On vehicles with drive select* , you can ad­
just the sporty sh ift characteristics in the
Dynamic driving mode .Swill appear in the
instrument cluster display instead of D.
-If you accidentally select N while driving,
take you r foot off the accelerator pedal im­
mediately and wait for the engine to slow
down to idle before selecting D/S.
