Your vehicle is equipped with an electromechani­
cal park ing brake. The parking brake is designed
to prevent the vehicle from rolling un intent ional­
ly and replaces the ha nd b rake .
In add ition to the normal functions of a trad i­
t ional ha nd brake, the electromechanical parking
brake prov ides va rious conven ience and safety
funct ions.
When starting from rest

Driving
- Occasional noises when the parking brake is
applied and released are normal and are not
a cause for concern.
- When the vehicle is parked, the parking
brake goes through a self-test cycle at regu­
lar intervals. Any associated noises are nor­
mal.
Parking
.,. Press the brake pedal to stop the vehicle .
.,. Pull the switch @¢
page 85, fig. 100 to set
the parking brake.
.,. Automatic transmission: Move the selector lev-
er to P.
.. Turn the engine off¢.&, .
.. Manual transmission: Shift into 1st gear.
.. When on inclines or declines, turn the steering
wheel so that the vehicle will roll into the curb
if it begins to move.
A WARNING
-
-When you leave your vehicle -even if only
briefly -always remove the ignition key. This
applies particularly when children remain in
the vehicle. Otherwise the children could
start the engine, release the parking brake
or operate electrical equipment (e.g. power
windows). There is the risk of an accident.
- When the vehicle is locked, no one -particu­
larly not children should remain in the vehi­
cle. Locked doors make it more difficult for
emergency workers to get into the vehicle -
putting lives at risk.
Starting from rest
The starting assist function ensures that the
parking broke is released automatically upon
starting .
Stopping and applying parking brake
.. Pull the switch @¢ page 85, fig. 100 to apply
the parking brake.
86
Starting and automatically releasing the parking brake
.. When you start to drive as usual, the parking
brake is automatically released and your vehicle
begins to move.
When stopping at a traffic signal or stopping in city traffic on vehicles with an automatic trans­
mission, the parking brake can be applied. The
vehicle does not have to be held with the foot­ brake. The parking brake eliminates the tendency
to creep with a drive range engaged . As soon as
you drive off as usual, the parking brake is re­ leased automatically and the vehicle starts to
move .
Starting on slopes
When starting on inclines, the starting assist pre ­
vents the vehicle from unintentionally rolling back. The braking force of the parking brake is
not released until sufficient driving force has
been built up at the wheels.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an in­
cline, do the following:
.. Keep the switch @¢ page 85, fig . 100 pulled
and depress the accelerator. The parking brake
stays applied and prevents the vehicle from
rolling backward.
.,. You can release the switch @once you are sure
that you are developing enough driving force at
the wheels by depressing the accelerator.
Depending on the weight of the rig (vehicle and
trailer) and the severity of the incline, you may
roll backwards as you start. You can prevent roll­
ing backwards by holding the parking brake
switch @pulled out and accelerating -just as
you would when starting on a hill with a conven­
tional hand brake .

A WARNING
- Always pay attention to the traffic around
you when the cruise control is in operation .
You are always respons ible for your speed
and the distance between your veh icle and
other veh icles .
-

-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
t ions are poor (such as ice, fog, gravel,
heavy ra in and hydroplan ing) -risk of acci­
dent .
- Turn
off the cruise control temporar ily when
enter ing turn lanes, h ighway exit lanes o r in
construction zones.
- Please note that inadvertently "rest ing"
your foot on the accelerator pedal causes
the cruise control not to brake. This is be­
cause the cruise cont rol is overridden by the
dr iver's acceleration.
- If a brake system ma lf u nction such as over­
heating occu rs when the c ruise contro l sys­
tem is switched on, the braking function in
the system may be switched
off . The other
cruise contro l functions remain active as
long as the indicator light
[lj;(i )~i~ (US mod­
els)/ .. (Canadian models) is on .
(D Tips
-Vehicles with manual transmission: You can
attain the set speed only if the gear that is
currently engaged will allow it, or if it does
not tax the engine and allows it to run
smooth ly. Therefore sh ift into a higher or
lower gear in a timely ma nner.
- The brake lights illuminate as soon as the
brakes apply automatically .

Introduction
Applies to vehicles : wi th mult itro nic/S tro nic/ tip tronic
The automatic transmission is controlled elec­
tronically. The transmission upshifts or down­
shifts automatically depend ing o n which drive
program is se lected .
When a
moderate driving style is used, the
transm ission selects the most economica l driv ing
mode . It will the n 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
dri ving style
characterized by quick accelerator
pedal movements, heavy acceleration, frequent
c hanges in speed and traveling at the maxim um
speed.
If desired, the driver can also select the gears
manually (tiptronic mode ) ¢ page 90.
Various automatic transmissions may be insta l­
l ed, depending on the model :
multitronic transmission
The mu ltitron ic t ransm iss ion is a continuously
variable transmission. Power is transferred using
a multidisk cl utch . In contrast to conventional
automat ic transmissions using shifting opera­
tions, the transmission ratio in the continuously
variable transmission is changed continuously.
This opt imizes the comfort leve l and conserves
fuel.
S tronic t ran smission
The S tronic is a d ua l-clutch transmission. Power
i s transferred using two clutches that work inde­
pendently from one another . They rep lace the
torque converter used in convent io nal automatic
transm issions and allow the vehicle to accelerate
withou t a noticeable inte rru pt io n in traction. ..,.
