Your vehicle is equipped with an electrome­ chanical parking brake. The parking brake is
designed to prevent the veh icle from rolling
u nintentionally and replaces the hand brake.
In add ition to the normal functions of a tradi­
t ional hand brake, the electromechanical
parking brake provides various convenience
and safe ty funct ions .
When starting from rest
-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.
Emergency brake function
An emergency brake ensures that the veh icle
can be slowed down even i f the normal brakes
fail ¢ page 79, Emergency braking.
A WARNING
If a drive rang e is engaged with the vehicle
stationary and the engine running, yo u
must in no instance accelerate carelessly.
Otherwise the vehi cle wi ll start to move
immediately -risk of an accident.
(0 Tips
-If the parking brake is applied with the
ign ition switched off, the ind icator lights
in the switch and - (USA models) .

80 On the road
soon as the switch @is released, or the accel­
erator pedal is depressed, emergency braking
stops .
.&_ WARNING
Emergency braking should only be used in
an emergency, when the normal foot brake
has failed or the brake pedal is obst ructed.
Using the parking brake to perform emer­
gency braking will slow yo ur vehicle down
a s if you had made a full brake application.
The laws of physics cannot be s uspended
even w ith ESC and its associated compo­
nents (ABS, ASR, EDS). In corners and
when road or weather conditions are bad,
a full brake application can cause the vehi­
cle to skid or the rear end to break away -
r isking an accident.
Speed warning system
Overview
The speed warning system helps you to keep
your driving speed below a set speed limit.
The speed warning system warns if the driver
exceeds a prev iously stored maximum speed.
A warning ton e will sound as soon as the vehi­
cle speed exceeds the set speed by about
3 mph (3 km/h). At the same time, a warning
symbol appears in the d isplay . The symbol's
appearance might be d ifferent in some mod­
e ls.
The speed warning sys tem has two warn ing
thresholds that function independently of
each other and that have somewhat different
purposes:
Speed warning 1
You can use speed warning 1 to set the maxi­
m um speed whil e you are dr iv ing . This setting
will remain in effect until you turn off the igni­
tion, assuming that you have not changed or reset the setting .
The. (USA models)/ . (Canada models)
speed warning symbol in the warning 1 dis­
play appears when you exceed the maximum speed
. It goes out when the speed falls be low
the stored maximum speed.
T he speed warning symbol will also go out if
the speed
exceeds the stored maximum speed
by more than about 25 mph (40 km/h) for at
least 10 seconds . The stored maximum speed
is de leted .
Speed warning 2
Storing warning 2 is recommended if you al­
ways
want to be rem inded of a ce rtain speed,
f or example when you are traveling in a coun­
try that has a general maximum speed limit,
or if you do not want to exceed a specified
speed for winter tires.
The. (USA models)/ . (Canada models)
speed warning 2 symbol appears in the dis­
play when you exceed the stored speed Limit.
Unlike warning 1, it will not go out until the
vehicle speed drops below the stored speed
limit .
Setting speed warning 2
c> page 81 .
(D Tips
Even though your vehicle is eq uipped with
a speed warning system, you should still
watch the speedometer to make sure you
are not driv ing faster than the speed limit.
Speed warning 1: setting a speed limit
Warning threshold 1 is set by the ISETI but­
ton.

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 veh icle and other vehicles . .,,.

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
off. The othe r cruise control f unctions re­
ma in active as long as the indicator light
@;rn~i~ (US models) !lB (Canadian mod­
els) is on.
The brake lights illuminate as soon as the brakes apply automatically.

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.
