Electro-mechanical parking brakeOperation
The electro-mechanical parking brake replaces the hand-
brake.– Pull switch ⇒fig. 136 to apply the parking brake. The
indicator lamp in the switch will light up.
– Depress the brake or accelerator pedal and press the
switch at the same time to release the parking brake. The
indicator lamp in the switch will go out.Your vehicle is equipped with an electro-mechanical parking brake.
The parking brake replaces the conventional handbrake, and is
mainly intended to prevent the vehicle from rolling away acciden-
tally.
However, the electro-mechanical parking brake also offers a number
of convenience and safety features in addition to the functions of a
normal handbrake.When driving away
•
The parking brake auto release function releases the parking
brake automatically when you wish to start moving ⇒page 122,
“Driving away from a standstill”.
•
When driving away on a gradient, the parking brake auto release
function prevents the vehicle from rolling back unintentionally. The
braking force of the parking brake is only released when there is
enough power at the wheels to make the vehicle move in the desired
direction.
Emergency braking function
An emergency braking function enables you to stop the vehicle even
if the conventional foot brake should fail to work ⇒page 123,
“Emergency braking function”.

with the ignition switched off.
WARNING
Never press the accelerator pedal or release the clutch inadvert-
ently if a gear is engaged or if the selector lever is not in position
P or N (on automatic vehicles) while the vehicle is stationary with
the engine running. The vehicle could otherwise start moving
immediately and possibly cause an accident.

workshop without delay ⇒page 31.
Note
•
The parking brake can be applied at any time - even when the
ignition is switched off. However, the ignition must be switched on
before the parking brake can be released.
•
Any slight noise which may be heard when the parking brake is
applied or released is quite normal and no cause for concern.
•
The parking brake runs an automatic test cycle at regular inter-
vals when the vehicle is parked. This may also cause a slight noise,
which is normal.
Parking
Please note the following points to ensure there is no risk
of the car rolling away accidentally after it is parked.Parking t he c ar
– Use the foot brake to stop the vehicle.
– Pull the switch to apply the parking brake.
– Automatic gearbox: Move the selector lever to P.
– Switch off the engine ⇒.
– Manual gearbox: Engage the first gear.
When parking on slopes
– Turn the steering wheel so that the vehicle would roll into
the kerb if it did start to move accidentally.
WARNING
•
Always take the key with you when leaving the vehicle – even
if you only intend to be gone for a short time. This is especially
important if children are left in the car. They might otherwise be
able to start the engine, release the parking brake or use power-
operated equipment such as the electric windows - this could lead
to injuries.
•
Do not leave anyone (especially children) in the vehicle when it
is locked. Locked doors could delay assistance in an emergency,
potentially putting lives at risk.
Driving away from a standstill
The parking brake auto release function releases the
parking brake automatically when you wish to start
moving.Applying the parking brake when stopping
– Pull the switch to apply the parking brake.
Releasing the parking brake when driving away
– Drive off in the normal way: the parking brake will be
released automatically and the vehicle will start moving.On vehicles with automatic gearbox, you can apply the parking
brake when stopping at traffic lights, etc. Then you do not have to
hold the car with the footbrake, as the parking brake will stop it
creeping forward while a gear is engaged in the automatic transmis-
sion. When you drive off in the normal way, the parking brake will be
released automatically and the vehicle will start moving.
Driving away on a slope
When driving away on a gradient, the parking brake auto release
function prevents the vehicle from rolling back unintentionally. The

Technical data
– To prevent the vehicle from rolling away, apply the
parking brake before moving off on steep gradients
⇒.
– As soon as you accelerate as normal, the parking brake
will automatically be released and the vehicle will start
moving.
Pa rking the c ar
– Press and hold the brake pedal ⇒.
– Apply the parking brake.
– Press and hold the interlock button, move the selector
lever to P and release the interlock button.Your vehicle is equipped with the hill hold assist function which
makes it easier to drive away on a slope. The system is activated
when you press and hold the brake pedal for a few seconds. When
you release the brake pedal the braking force will be maintained for
a moment in order to prevent the vehicle rolling back when you drive
away.
The engine c an only be started when the selector lever is at P or N.
On level ground it is sufficient to move the selector lever to P. On a
gradient the parking brake should be applied first and the selector
lever should be moved to P. This reduces the load on the locking
mechanism and makes it easier to move the selector lever out of
position P.
WARNING
•
Do not press the accelerator while selecting a gear with the
vehicle stationary and the engine running, as this could cause an
accident.
•
Please note that some power will still be transmitted when you
stop temporarily with the selector lever in position D, S or R. For this reason, to avoid risking an accident, apply the footbrake firmly
when stopping to prevent the vehicle rolling away.
•
Never move the selector lever to R or P when driving, as this
could cause an accident.
Applies to vehicles: with multitronic®Selector lever positions
This section covers all the selector lever positions.The current selector lever position is shown in the instrument
cluster display.
P - Parking lock
This locks the driving wheels mechanically. The parking lock must
only be engaged when the vehicle is stationary ⇒.
The interlock button (the button in the selector lever handle) must
be pressed in and the brake pedal must be depressed before
moving the selector lever either in or out of position P. The lever can
only be moved out of position P when the ignition is on.
R - Reverse gear
When reverse gear is engaged the gearbox automatically selects the
lowest gear ratio.

Automatic gearbox 132Reverse gear must only be engaged when the vehicle is stationary
and the engine is idling ⇒.
To move the selector lever to position R, press in the interlock
button and at the same time press the brake pedal. Depending on
the model, one or two reversing lights will come on in selector lever
position R (when ignition is switched on).
N - Neutral
In this position the gearbox is in neutral ⇒.
D - Drive (forwards)
In this position the gearbox automatically selects the best gear
ratio. This depends on the engine load, the road speed and the
dynamic gear control program (DCP).
Press the brake pedal when moving the selector lever from N to D if
the vehicle is stationary or at speeds below 5 km/h ⇒.
In some situations (such as on mountain roads or when towing a
trailer or caravan) it can be advantageous to switch temporarily to
tiptronic mode ⇒page 134, so that the gear ratios can be selected
manually to suit the driving conditions.
S - Sport position
Select this position if you wish to take full advantage of the car's
performance. This setting makes use of the engine's maximum
power output. When accelerating the gear shifts will be noticeable.
Press the brake pedal when moving the selector lever from N to S if
the vehicle is stationary or at speeds below 5 km/h ⇒.
WARNING
•
Never move the selector lever to R or P when driving, as this
could cause an accident.
•
In selector position D or S the vehicle must always be held with
the foot brake when the engine is running. This is because an auto-
matic gearbox still transmits power even at idling speed, and the vehicle tends to “creep”. The throttle must on no account be
opened inadvertently (for instance by hand from the engine
compartment) when a gear is engaged with the vehicle stationary.
The vehicle could otherwise start moving immediately (in some
cases even if the parking brake is engaged) and possibly cause an
accident.
•
To avoid accidents, apply the parking brake and put the
selector lever in position P before opening the bonnet and working
on the vehicle with the engine running. Please observe the impor-
tant safety warnings ⇒page 231, “Working on components in the
engine compartment”.
Applies to vehicles: with multitronic®Selector lever lock
The selector lever lock prevents gears from being
engaged inadvertently, so that the vehicle is not set in
motion unintentionally.The selector lever lock is released as follows:
– Switch on the ignition.

– Press the brake pedal and at the same time press in the
interlock button.Automatic selector lever lock
The selector lever is locked in the P and N positions when the igni-
tion is on. The brake pedal must be depressed before the lever can
be moved out of either of these positions. The following message
appears in the instrument display as a reminder for the driver when
the selector lever is in position P or N:
WHEN STATIONARY APPLY FOOTBRAKE WHILE SELECTING GEAR.
The selector lever lock only works if the vehicle is stationary or
driving at speeds up to 5 km/h. At higher speeds the selector lever
lock in the N position is disengaged automatically.
The selector lever lock is not engaged if the selector lever is moved
quickly through position N (e.g. when shifting from R to D). This
makes it possible, for instance, to “rock” the vehicle backwards and
forwards if it is stuck in snow or mud. The selector lever lock
engages automatically if the brake pedal is not depressed and the
lever is in position N for more than about a second.
Interlock button
The interlock button on the selector lever handle prevents the driver
from inadvertently engaging particular gears. Press the button in to
disengage the selector lever lock. The illustration shows the selector
lever positions in which the button has to be pressed, highlighted in
colour ⇒page 132, fig. 146.
Safety interlock for ignition key
The key can only be withdrawn with the ignition switched off and
the selector lever in position P. When the ignition key is removed,
the selector lever is locked in position P.
Applies to vehicles: with multitronic®Kick-down feature
The kick-down feature is designed to give maximum
acceleration.When the accelerator pedal is pressed right down past the point of
resistance at full throttle, the gearbox will select a lower gear,
depending on road speed and engine speed. While you keep the
accelerator depressed the engine speed is automatically controlled
to give your vehicle maximum acceleration.
WARNING
Please note that if the road surface is slippery or wet, the kick-
down feature could cause the driving wheels to spin, which could
result in skidding.Applies to vehicles: with multitronic®Dynamic gear control program (DCP)
The multitronic
® gearbox is controlled electronically.
The vehicle is equipped with an electronically controlled gearbox.
The gear ratios are selected automatically according to preset gear-
shift programmes.
When you drive at moderate speeds the gearbox will select the most
economical shift programme. It will then change up early and delay
the downshifts to give better fuel economy.
If you drive at higher speeds with heavy acceleration, if you open the
throttle quickly, or if you use the kick-down or the car's maximum
speed, the gearbox will automatically select the more “sporty” shift
programmes.
The gearbox is self-adapting, and continuously selects the most
suitable shift programme. At the same time, the driver can also
make the gearbox switch to a more "sporty" programme by pressing

Activating
– Engage reverse gear to automatically activate the
parking system plus, or
– Press the switch

⇒page 138, fig. 152 in the centre
console to activate the parking system plus manually.
You will hear a short beep to confirm that the parking
system has been activated. The indicator lamp in the
switch will light up.
Deactivating
– Drive forwards faster than approx. 10 km/h, or
– Switch off the ignition to automatically deactivate the
complete parking system, or
– Press the switch

⇒page 138, fig. 152 to deactivate the
parking system plus manually. The indicator lamp in the
switch will go out.
Activate the system manually if you are driving forwards and would
like the system to give a warning as you approach potential obsta-
cles, for instance when parking.
The measuring range of the sensors in the front and rear bumpers
starts at approximately:
Warning beeps
The warning beeps are produced by sound boxes. The volume and
pitch of the beeps can be adjusted in the MMI ⇒page 148.Mute function
An acoustic proximity warning is cancelled when you apply the
parking brake or move the selector lever of the automatic gearbox
to position P. However, the system remains active. The warning
beeps will start again as soon as you release the parking brake or
move the selector lever out of position P if the system has detected
an obstacle.
Reversing/driving forwards
When the vehicle is reversing/driving forwards, the system starts to
beep if it registers an obstacle within its detection range (see
above). The warnings will beep increasingly rapidly as the vehicle
approaches the obstacle.
When the vehicle is less than approx. 0.30 m away from the obstacle
the warning tone will sound continuously. From here at the latest,
the driver should then not reverse/drive forwards any further.
The volume of the warning beeps will be gradually reduced after
about 4 seconds if the vehicle remains at a constant distance from
a detected obstacle (it will not be reduced if the obstacle is closer
than 0.30 m). The warnings will then return to the normal volume if
the vehicle approaches the detected obstacle again.
Parking
If the parking manoeuvre involves shunting backwards and
forwards, the warning sound will be switched off temporarily while
you change gear. The proximity graphic will, however, still be
displayed on the MMI screen. The warnings will then return to the
normal volume if the vehicle approaches the detected obstacle
again.
Graphic display
The segments in the MMI display indicate the distance between the
vehicle and a detected obstacle. The number of segments shown
depends on the obstacle in front of or behind the vehicle. The closer
the vehicle gets to the obstacle the closer the segments move
towards the vehicle in the graphic ⇒page 138, fig. 153. At the latest
