low temperatures.
(D Note
Avoid high eng ine rpm, fu ll throttle and
heavy engine loads unti l the engine has
reached operating tempe rat ure -other­
wise you r isk eng ine damage.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions.

-After starting a cold engine, there may
be a brief period of increased no ise be­
cause the oil pressure must first bu ild up
in the hydraulic valve adjusters. This is
normal and not a cause for concern.
- If you leave the veh icle with the ignition

Operation
The electromechanical parking broke replaces
the hand broke.

parking brake. The indicator lights in the
switch and • (USA models) . (Cana-

"'With the ignition switched on, step on the
brake pedal or the accelerator pedal and
press the switch @at the same time to re­
lease the parking brake. The indicator lights
in the switch and. (USA models)/ . (Can­
ada models) in the instrument cluster go
out.
Your vehicle is equipped with an electrome­
chanical parking brake. The parking brake is
designed to prevent the vehicle from rolling unintentionally and replaces the hand brake.
In addition to the normal functions of a tradi­
tional hand brake, the electromechanical
parking brake provides various convenience
and safety functions .
When starting from rest
- The integral starting assist helps you when
driving by automatically releasing the park­
ing brake ¢
page 88, Starting from rest.
-When starting on inclines , the starting as-
sist prevents the vehicle from unintentional-
ly rolling back. The braking force of the
parking brake is not released until sufficient

8_ WARNING
If a gear or a drive range (automatic trans­
mission) is engaged with the vehicle sta­
tionary and the engine running, you must in no instance accelerate or release the
clutch* carelessly. Otherwise the vehicle
will start to move immediately -risk of an
accident .
(D Tips
-If the parking brake is applied with the
ignition switched off, the indicator lights
i n the sw itch and -(USA models)/ .
(Canada models) in the instrument clus­
ter will go out after a certain per iod of
time .
- Occas iona l noises when the park ing
brake is applied and re leased a re no rma l
and are not a ca use for concern.
- Wh en the vehicle is parked, the parking
brake goes through a se lf-test cycle a t
regular intervals. Any assoc iated noises
are no rma l.
Parking
.. Press the brake peda l to stop the v ehicle .

.. Manua l transm ission: Shift into 1st gear .
.. When on incl ines or decli nes, tu rn the steer ­
i ng wheel so th at the vehicle will roll into
the curb if it begins to move .
8_ WARNING
-When you leave your vehicle -even if on­
ly briefly -always remove the ignition
key . Th is applies particularly whe n chil­
dren remain in the vehicle . Otherwise the
children could star t the eng ine , release
the par king brake or operate electrical
equipme nt (e.g. power windows). There
is the risk of an accident.
- W hen the veh icle is locked, no one -pa r­
ticularly not children should remain in
the vehicle . Locked doors make it more
difficult for emergency worke rs to get in­
to the vehicle -putting lives at risk .
· Starting from rest
The starting assist function ensures that the
parking broke is rel eased automatically upon
starting.

vehicle begins to move .
When stopping at a t raffic signal or stopping
in city t raffic on vehicles with an a utomatic
t ransmission, the parking brake can be ap­
plied. The vehicle does not have to be held
with the footbrake . The parking brake elimi­
nates the tendency to creep w ith a dr ive range
engaged. As soon as you drive off as usual,
the parking brake is re leased automat ically
and the vehicle starts to move .
Starting on slop es
When starting on inclines, the starting assist
prevents the vehicle from un in tent ionally roll­
ing back. The braking force of the parking
brake is not released until suffic ient driving
force has been built up at the wheels .

may vary, depending on the type of display in
your vehicle.
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 responsib le for
your speed and the distance between
your vehicle and other vehicles.
On th e road 91
-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 ra in and hydro­
plan ing) -risk of accident .
- Turn off the cruise control temporarily when enter ing 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
because the cruise control is overridden
by the driver's accelera tion.
- I f a brake system malfunction such as
overhea ting occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off . The other cruise contro l functions re­
main active as long as the indicator light
lij;(i )~14 (US models) ;a (Canad ian mod­
els) 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 smoothly . Therefore shift into a
higher or lower gear in a timely manner .
- The brake lights illuminate as soon as
the brakes apply automatically.

ments, tap the lever in the

(D Note
Always depress the clutch pedal fully when
changing gears . Do not hold the vehicle on
a hill with the clutch pedal partially de­

Introduction
Applies to vehicles: with multitronic/S tronic/tiptronic
The automatic transmission is controlled elec ­
tronically. The transmission upshifts or down­
shifts automatically depending on which drive
program is selected .
When a
moderate driving style is used, the
transmission selects the most economical
driving mode. It will then change up early and
delay the downshifts to give better fuel econ ­
omy .
The transmission switches to a sporty mode
after a kick-down or when the driver uses a
sporty driving style characterized by quick ac­
celerator pedal movements, heavy accelera­
t ion, frequent changes in speed and trave ling
at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode)~ page 93 .
Various automatic transmissions may be in­
stalled, depending on the model:
multitronic transmission
The multitronic transmission is a continuously
variable transmission. Power is transferred us­
ing a multidisk clutch. In contrast to conven­
tional automatic transmissions using shifting
operations, the transmission ratio in the con­
tinuously var iable transmission is changed
continuously . This optimizes the comfort level
and conserves fuel.
S tronic transmission
The S tronic is a dual-clutch transmission .
Power is transferred using two clutches that
work independently from one another_ They
replace the torque converter used in conven­
tiona l automatic transmissions and allow the ..,_
