children could start the eng ine, release
the park ing brake or operate electrical
equ ipment (e.g. power windows). There
is t he risk of an acc ident .
- When the veh icle is locked, no one -par­
ticularly not children should rema in in
the vehicle. Locked doors make it more

parking brake is released automatically upon
starting .
Stopping and applying parking brake
• Pull the switch®¢ fig. 92 to app ly the
parking brake.
Sta rting and automatically rel easing the
parking brake
• When you start to drive as usual, the park­
ing brake is automatically released and your
veh icle beg ins to move .
When stopping at a traffic signal or stopping in city traff ic on vehicles with an automatic
transmission, the parking brake can be ap­ plied . The vehicle does not have to be he ld
with the footbrake. The pa rking brake elimi­
nates the tende ncy to creep w ith a dr ive range
engaged. As soon as yo u drive off as usu al,
t h e parking bra ke is re leased automatic ally
and the vehicle starts to move.
Starting on slopes
When starting on inclines, the sta rting assist
prevents t he vehi cle from u nintent ionally roll­
ing back. The bra king force of the par kin g
brake is no t re leased unti l su ff ic ient d riving
f orce has been built up at the wheels.
(D Tips
F o r safety reaso ns, t he pa rking br ake is re­
l eased automatic ally o nly when the d riv­
e r's safety belt is engaged in the buckle .

82 On the road
Starting off with a trailer
To prevent rolling back unintentionally on an
incline , do the following:
.,. Keep the switch@¢ fig. 92 pulled and de­
press 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 a re develop ing enough dr iv ing
f orce at the wheels by dep ress ing the accel­
erator.
Depending on the weight of the r ig (veh icle
and tra iler) and the seve rity of the in cli ne , you
may roll backwards as you start . You can pre ­
vent rolling backwards by holding the parking brake switch @ pulled out and accelerating -
just as you would when starting on a hill with
a conventional hand brake.
Emergency braking
In the event that the conventional brake sys­tem
foils or locks.
... In an emergency, pull the switch @
¢
fig. 92 and continue to pu ll it to slow your
vehicle down with the parking brake.
.,. As soon as you release the sw itch @ or ac-
celerate, the braking process stops.
If you pu ll the switch @and ho ld it above a
speed of about 5 mph (8 km/h), the emergen­
cy braking function is in iti ated. The vehicle is
braked at al l four wheels by activating the hy­
d raul ic brake system . T he brake performance
is simi lar to making an eme rgency stop¢.&. .
In order not to activate the emergency brak­ ing by mistake, an audible warning tone (buz­
zer) sounds when the switc h@ is pulled . As
soon as the switch @is released, or the accel­
e rator pedal is dep ressed , emergency b ra ki ng
stops.
.&_ WARNING
Emergency braking sho uld only be used in
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed . Using the par
king brake to pe rform emer­
gency braking will s low your veh icle down
as if you had made a full brake application.
The laws of p hysics cannot be suspended
even with ESC and i ts associated compo­
nents (ABS, ASR, EDS). In corners and
when road o r weathe r cond itions are bad,
a full brake appl ication can ca use the vehi­
cle to s kid or the rear end to break away -
risking an acciden t.
Speed warning system
Overview
The speed warning system helps you to keep
your driving speed below a set speed limit.
T he speed warning system warns if the driver
e xc eeds a previously stored max imum speed .
A warning tone w ill sound as soon as the vehi ­
cle speed exceeds the set speed by abou t
3 mph (3 km/h) . At the same t ime, a warning
symbol appears in the display . T he symbol's
appea rance might be different in some mod­
els .
The speed warn ing system has two warning
t hr esholds that funct io n in dependent ly of
each other and that have somewhat diffe rent
purposes:
Speed wa rning 1
You can use speed warning 1 to se t the maxi­
mum speed while you are driving . T his setting
will remai n in effect unt il you turn off the ig ni­
t io n, assuming that you have not changed or
r ese t the sett ing.
The . (USA mode ls)
I. (Canada mode ls)
speed warning symbol in the warning 1 dis­
play appears when you exceed the maximum
speed .
It goes ou t when the speed falls be low
the stored maximum speed .
T he speed warn ing 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 sto red max imum speed
is de leted . .,..

Speed warning 2
Storing w arning 2 is recomme nded if you al­
ways want to be rem inded of a certa in speed ,
for example when yo u are traveling in a coun­
try that has a general ma ximum speed limit,
or if you do not want to exceed a spec ified
speed for winter tires.
The . (U SA mode ls)
I. (Canada mode ls)
speed warn ing 2 symbo l appears in the dis­
p lay when you exceed the stored speed lim it.
Unlike warning 1, it will not go out u ntil the
ve hicle speed drops below the stored speed
limit.

may vary, depending on the type of display in
your veh icle.
The speed is kept constant by modifying en­
gine power or through an active brake inter­
vention.
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. -
For reasons of safety , cruise control
should not be used in the city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as ice, fog, gravel, heavy rain and hydro­
plan ing) - risk of accident.
- Turn off the cruise control temporarily
when enter ing turn lanes, highway exit
lanes or in constr uction zones .
- Please note that inadve rtently "resting"
your foot on the accelerator pedal causes
the cruise control not to brake. This is
because the cruise control is overridden
by the drive r's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off . The other cruise control functions re­
main active as long as the indicator light
[ff;(l)~i4 (US models) ;B (Canadian mod­
els) is on.
(D Tips
The brake lights illuminate as soon as th e
brakes app ly automatically.

86 Transmi ssion
Transmission
multitronic ®, S tronic ®,
tiptronic
Introduction
Appl ies to vehicles: with multitronic/5 tronic/tiptronic
The automatic transmission is controlled elec­
tronically. The transmission ups hifts or down­
shifts automatically depending on which drive program is se lected.
When a
moderate driving style is used, the
transmission se lects the most economical
driving mode. It wi ll then change up early and
de lay the downshifts to g ive better f uel econ­
omy.
The transmission switches to a sporty mode after a k ick-down or when the dr iver uses a
sporty driv ing style characterized by qu ick ac­
celerator peda l movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed .
If desired, the driver can a lso sel ect the gears
manually (tiptronic mode ) q page 86.
Various a utomatic transmissions may be in ­
stalled, depend ing on the mode l:
multitronic ® transmission
The mult it ron ic® transm ission is a co nti nuous ­
l y var iable transmission. Power is transferred
using a m ultidisk clutch. In contrast to con­
ventiona l automatic transmissions using sh ift­
ing operat ions, the transmission ratio in the
continuously variable transm ission is changed
continuously. This optimizes the comfort level
and conserves fuel.
S tronic ® transmission
The 5 tronic ® is a d ual-clutch transmission .
Power is transferred using two clutches that
work independently from one another. They
replace the to rque conve rter used in conven­
tional automa tic transm iss ions and allow the
ve hicle to acc elerate without a noticeable in­
ter ruption in traction.
tiptronic transmission
In the t ipt ro ni c transm iss ion, powe r is trans­
f erred by a torque converter .
