WARNING
● The parking aid is not a substitute for the driver paying proper attention
and it is always the driver's responsibility to take care when parking the vehi-
cle or carrying out similar manoeuvres.
● You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin post, trailer drawbar etc., behind your vehi-
cle. Such an obstacle might not be within the range detected by the sensors.
● Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the parking aid. Thus, these objects or
people who wear such clothing are not recognised by the sensors of the park-
ing aid. Note
● The parking aid does not operate if you are towing a trailer (applies to models
which feature a factory-fitted towing device).
● A system fault is indicated if a warning signal sounds for about 5 seconds after
switching the ignition on and engaging reverse gear and there is no obstacle close
to your vehicle. It is possible that the audible warning does not function correctly
(an obstacle behind the vehicle may not be detected - take extra care). Have the
fault rectified by a specialist workshop.
● If the audible warning sounds for 3 seconds after switching the ignition on and
engaging the reverse gear, a fault has occured in the system. It is possible that
the audible warning does not function correctly (an obstacle behind the vehicle
may not be detected - take extra care). Have the fault rectified by a specialist
workshop.
● The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
● If the parking aid is activated and the selector lever of the automatic gearbox
is in the position P , warning signal indicates interruption (vehicle can no longer
move). Cruise control system (CCS)
Introduction The cruise control system (CCS) maintains a constant speed, more than 30 km/h
(20 mph), once it has been set, without you having to depress the accelerator
pedal. This is only possible within the range which is permitted by the power out-
put and braking power of the engine. The cruise control system makes it possible
- particularly on long journeys - for you to rest your
“accelerator foot”
. WARNING
● For safety reasons, the cruise control system must not be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads,
loose gravel) - risk of accident!
● In order to prevent unintentional use of the cruise control system, always
switch off the system after use. Note
● Models fitted with a manual gearbox: Always depress the clutch pedal if you
switch on the cruise control system when the gearbox is in Neutral! Otherwise the
engine can rev up unintentionally.
● The cruise control system is not able to maintain a constant speed when driv-
ing on steep downhill sections. The weight of the vehicle increases the speed at
which it travels. One should shift down in good time to a lower gear or slow the
vehicle down by applying the foot brake.
● It is not possible on vehicles fitted with an automatic gearbox to switch on the
cruise control system if the selector lever is in the position P, N or R. 87

Storing a speed
Fig. 86 Operating lever: Rocker button
and switch of the cruise control system
The cruise control system is operated by means of the switch A and the rocker
button B in the left lever of the multi-functional switch.
– Press the switch A ⇒
fig. 86 into the position ON.
– After the desired speed has been reached, press the rocker button B into the
SET- position - the current speed is stored.
After you have released the rocker button B out of the position SET-, the speed
you have just stored is maintained at a constant speed without having to depress
the accelerator.
You can increase the speed by depressing the accelerator. Releasing the accelera-
tor will cause the speed to drop again to the set speed.
This does not apply, however, if you drive at a speed which is more than 10 km/h
higher than the saved speed for a period of more than 5
minutes. The stored
speed will be cancelled in the memory. You then have to re-store the desired
speed.
One can reduce the speed in the usual manner. The system is switched off tempo-
rarily by actuating the brake or clutch pedal ⇒ page 88.WARNING
First ensure that it is not too high for the traffic conditions which exist at that
moment before resuming the stored speed. Changing a stored speed You can also change the speed of the vehicle without depressing
the accelerator.
Faster
– You can increase the stored speed without depressing the accelerator, by
pressing the rocker button B ⇒
fig. 86 into the RES+
position.
– The speed of the car will increase continuously if you hold the rocker button
pressed in the RES+ position. Once the car has reached the desired speed, re-
lease the rocker button. The set speed is then stored in the memory.
Slower
– You can decrease the stored speed by pressing the rocker button B in the
SET- position.
– Holding down the pushbutton pressed in the SET- position will cause the
speed of the vehicle to reduce continuously. Once the car has reached the de-
sired speed, release the rocker button. The set speed is then stored in the
memory.
– If you release the rocker button when the car is travelling at a speed of less
than 30 km/h, the speed is not stored, the memory is erased. It is then neces-
sary to again store the speed with the rocker button B in the position
SET-
after an increase in speed of the vehicle to more than 30 km/hour.
Switching off the cruise control system temporarily –
You can switch off the cruise control system temporarily by depressing the
brake pedal or clutch pedal, on vehicles fitted with an automatic gearbox only
with the brake pedal.
– You can switch off temporarily the cruise control system, if you press the
switch A in the middle position.
The set speed remains stored in the memory.
The Resumption of the stored speed is achieved by releasing the brake or clutch
pedal, on vehicles fitted with automatic gearbox only after releasing the brake
pedal and after shortly pressing the rocker button B

“START-STOP” Fig. 87 Centre console: START-STOP
System button
The “START-STOP” system helps you to save fuel while at the same time reducing
harmful exhaust emissions and CO 2 emissions.
The function is automatically activated each time the ignition is switched on.
In the start-stop mode, the engine automatically switches to the vehicle's idle
phase, e.g. when stopped at traffic lights.
Information regarding the current state of the “START-STOP
” system is indicated
in the display of the instrument cluster.

WARNING
● If the engine is switched off, neither the brake booster nor the electrohy-
draulic power steering operates.
● Never let the vehicle roll with the engine switched off. CAUTION
If the “START-STOP” system is used at very high outside temperatures over a very
long period of time, the vehicle battery can be damaged. Note
● Changes to the outdoor temperature can have an effect on the internal tem-
perature of the vehicle battery even after several hours. For example, if the vehi-
cle is standing outside for a long period of time at a temperature below freezing
or is in direct sunlight, it may take several hours until the temperature inside the
battery reaches the appropriate temperature for the START-STOP system.
● In some instances it may be necessary to start the engine manually with the
ignition key (e.g. when the seat belt is not inserted or the driver's door is opened
for more than 30 seconds). Follow the messages in the instrument cluster display.
● If the Climatronic is running in automatic mode, under certain conditions, the
engine may not switch off automatically. 90

Automatic gearbox
Automatic gearbox Information for driving with the 6-speed automatic gearbox The maximum speed is reached in the 5th gear. The 6th gear serves as an eco-
nomic driving programme, which is intended to reduce the fuel consumption.
Shifting up and down through the gears is performed automatically. You can also,
however, switch the gearbox over into the
Tiptronic mode. This mode makes it
possible for you to also shift gears manually ⇒ page 95.
Starting-off and Driving
– Depress the brake pedal fully and keep it depressed.
– Press the Shiftlock button (button in handle of the selector lever), move the
selector lever into the desired position, e.g. D ⇒ page 93, and then release
the Shiftlock button.
– Wait a moment until the gearbox has shifted (a slight engagement nudge can
be felt).
– Release the brake pedal and depress the accelerator ⇒ .
Stop
– The selector lever position N does not have to be selected when stopping just
for a short time, such as at a cross roads. It is sufficient to hold the vehicle sta-
tionary using the foot brake. The engine can, however, be allowed just to idle.
Parking
– Depress the brake pedal and hold it depressed.
– Apply the handbrake firmly.
– Press and Shiftlock button in the selector lever, move the selector lever to P
and then release the Shiftlock button.
The engine can only be started when the selector lever is in position P or N . If the
selector lever is not in the P or N positions when locking the steering, switching
the ignition on or off or when leaving the engine on, the following message will
appear in the Information display Move selector lever to position P/N! or, in the
instrument cluster display: P/N. It is sufficient to engage selector lever position
P when parking on a flat surface.
When parking on a slope you should first apply the handbrake firmly and then
move the selector lever into position P. This is to ensure that there is no excessive
pressure acting on the lock mechanism and that it is easier to subsequently move
the selector lever out of position P. If the selector lever is not in the P positin
when the driver's door is open and the ignition is switched off, or if it is not in the
P position when the ignition is switched off and the driver's door is opened, the
following message will appear in the Information display: Move selector lever to
position P! or, in the instrument cluster display: P. The message disappears af-
ter a few seconds by switching on the ignition or by moving the selector lever into
the position P .
If the selector lever position N is selected by accident while driving it is first nec-
essary to release pressure on the accelerator pedal and wait for idling speed of
the engine to be reached before engaging a drive position in the selector lever. WARNING
● Do not depress the accelerator when changing the position of the selector
lever if the car is stationary and the engine is running - risk of accident!
● Never move the selector lever into position R or P when driving - risk of an
accident!
● When the engine is running and the vehicle is stationary, it is necessary to
hold the car with the brake pedal in all the positions of the selector lever (ex-
cept P and N) since the power transmission is never completely interrupted,
also not when the engine is idling - the vehicle creeps.
Information for driving with the automatic gearbox DSG The abbreviation DSG means Direct shift gearbox (Direct shift gear-
box).
Two independent clutches are needed for the power transmission between the
engine and the gearbox. These replace the torque converter of the conventional
automatic gearbox. Their shifting is matched in such a way that there are no jerks
when shifting the gear and the power transmission of the engine to the front
wheels is not interrupted. Shifting up and down through the gears is performed £ 91

automatically. You can also, however, switch the gearbox over into the
Tiptronic
mode. This mode makes it possible for you to also shift gears manually
⇒ page 95.
Starting-off and Driving
– Depress the brake pedal fully and keep it depressed.
– Press the Shiftlock button (button in handle of the selector lever), move the
selector lever into the desired position, e.g. in D, and then release the Shiftlock
button.
– Release the brake pedal and depress the accelerator ⇒ .
Stop
– The selector lever position N does not have to be selected when stopping just
for a short time, such as at a cross roads. It is absolutely sufficient to hold the
stopped vehicle stationary by depressing the foot brake. The engine can, how-
ever, be allowed just to idle.
Parking
– Depress the brake pedal and hold it depressed.
– Apply the handbrake firmly.
– Press and Shiftlock button in the selector lever, move the selector lever to P
and then release the Shiftlock button.
The engine can only be started when the selector lever is in position P or N . If the
selector lever is not in the P or N positions when locking the steering, switching
the ignition on or off or when leaving the engine on, the following message will
appear in the Information display Move selector lever to position P/N! or, in the
instrument cluster display: P/N. At temperatures below -10 °C the engine can
only be started in the selector lever position P.
It is sufficient to engage selector lever position P when parking on a flat surface.
When parking on a slope you should first apply the handbrake firmly and then
move the selector lever into position P. This is to ensure that there is no excessive
pressure acting on the lock mechanism and that it is easier to subsequently move
the selector lever out of position P. If the selector lever is not in the P positin
when the driver's door is open and the ignition is switched off, or if it is not in the
P position when the ignition is switched off and the driver's door is opened, the
following message will appear in the Information display: Move selector lever to
position P! or, in the instrument cluster display: P. The message disappears af-
ter a few seconds by switching on the ignition or by moving the selector lever into
the position P . If the selector lever position
N is selected by accident while driving it is first nec-
essary to release pressure on the accelerator pedal and wait for idling speed of
the engine to be reached before engaging a drive position in the selector lever. WARNING
● Do not depress the accelerator when changing the position of the selector
lever if the car is stationary and the engine is running - risk of accident!
● Never move the selector lever into position R or P when driving - risk of an
accident!
● If you are stopping at a hill (downhill section), never try to hold the car sta-
tionary with the gear engaged by means of the “accelerator
”, this means by
letting the clutch slip. This can lead to overheating of the clutch. If there is a
risk of overheating of the clutch due to overload, the clutch is opened auto-
matically and the vehicle rolls backward - risk of accident!
● If you must stop at a slope, depress and hold the brake pedal, so that you
can prevent the vehicle from rolling back. CAUTION
● The double clutch on the automatic gearbox DSG is equipped with an overload
protection. If you make use of the uphill function on a vehicle which is stationary
or driving slowly uphill, it will result in an increase of thermal stress of the clutch-
es.
● In the event that they overheat, the warning light and a warning text ap-
pears in the information display ⇒ page 18. In such a case bring the vehicle to a
stop, switch off the engine and wait until the warning light and the warning go
out - risk of gearbox damage! You can continue the trip as soon as the warning
light and the warning go out. 92

Selector lever positions
Fig. 88 Selector lever/information display: Selector lever positions
The selector lever position you have engaged is shown in the information display
of the instrument cluster with the corresponding gear symbol highlighted
⇒ fig. 88 - on the right. In the positions D and S the gear you have already engag-
ed will be additionally displayed on the display.
P - Parklock
The driven wheels are locked mechanically in this position.
The Parklock must only be engaged when the vehicle is stationary ⇒ .
If you wish to move the selector lever into or out of this position, you must press
the Shiftlock button in the handle of the selector lever and at the same time de-
press the brake pedal.
R - Reverse gear
Reverse gear must only be engaged when the vehicle is stationary and the engine
idling ⇒ .
The brake pedal must be depressed and at the same time the Shiftlock must be
pressed, if you wish to obtain the selector lever positions R, P or N.
When the ignition is switched on and the selector lever is in position R, the re-
verse lights will come on.
N - Neutral
The transmission is in Neutral in this position. The brake pedal must be depressed (if the lever is in its position for longer than 2
seconds) in order to move the selector lever out of the position
N into the position
D, with the ignition switched on, on a vehicle travelling at less than 5 km/hour or
on a stationary vehicle.
D - Position for driving forward
When the selector lever is in this position, the forward gears are shifted up and
down automatically in line with engine load, vehicle speed and the dynamic shift
programme.
You must depress the brake pedal ⇒ if you wish to move the selector lever into
position D from N when the vehicle is travelling at less than 5 km/hour or is sta-
tionary.
In certain circumstances (e.g. when driving in mountainous regions or when tow-
ing a trailer) it may be beneficial to select the manual shift programme
⇒ page 95 for a short time in order to adapt the gearbox ratios manually to the
driving situations.
S - Position for sporty style of driving
Shifting up later into a higher gear makes it possible to fully exploit the power po-
tential of the engine. The gearbox also then shifts down at higher engine speeds
as in the position D .
The gearbox does not shift into the 6th gear in the position S, because the maxi-
mum speed is reached with the 5th gear 1)
.
The Shiftlock on the selector lever grip must be pressed when moving the selec-
tor lever out of the position D into the position S. WARNING
● Never move the selector lever into position R or P when driving - risk of an
accident!
● When the engine is running and the vehicle is stationary, it is necessary to
hold the car with the brake pedal in all the positions of the selector lever (ex-
cept P and N) since the power transmission is never completely interrupted,
also not when the engine is idling - the vehicle creeps. £1)

WARNING (Continued)
● You must on no account unintentionally operate the throttle (e.g. by hand
from the engine compartment) if a drive position is engaged when the car is
stationary. The vehicle would otherwise immediately start off - also when the
handbrake is firmly applied - risk of an accident!
● You must move the selector lever into position P and firmly apply the
handbrake first before you or any other person opens the bonnet and starts
working on the engine when it is running - risk of accident! It is also essential
to observe all warnings ⇒ page 153, Working in the engine compartment.
Selector lever lock Automatic selector lever lock
With the ignition on, the selector lever is locked when it is in the positions P and
N. You must first of all depress the brake pedal in order to move the selector lever
out of this position. The warning light ⇒ page 25 lights up in the instrument
cluster as a reminder for the driver when the selector lever is in the positions P
and
N.
A time delay element ensures that the selector lever is not blocked when rapidly
switching over the position N (e.g. from R to D). This does, for example, allow one
to seesaw out a stuck vehicle. The selector lever lock will click into place if the lev-
er is in the N position for more than 2 seconds without the brake pedal being
pressed.
The selector lever lock is only active if the vehicle is stationary or moving at speed
of less than 5 km/hour. The lock is switched off automatically into position N
when the car is travelling at a higher speed.
Shiftlock button
The Shiftlock button in the handle of selector lever prevents certain selector lever
positions being engaged inadvertently. The selector lever lock is cancelled when
you press the Shiftlock button.
Keylock 1)
- Ignition key withdrawal lock
You can only withdraw the ignition key after switching off the ignition if the selec-
tor lever is in position P. If the ignition key is withdrawn, the selector lever is
blocked in position P. Kickdown function The kickdown function provides you with maximum acceleration
power.
Fully depressing the accelerator pedal allows the kickdown function to be activa-
ted in the desired driving program. This function has precedence over the driving
programme and serves for maximum acceleration of the vehicle when exploiting
the maximum power potential of the engine without taking into account the cur-
rent selector lever position ( D, S or Tiptronic ). The gearbox shifts down to one or
several gears in line with the driving state and the vehicle accelerates. The gear-
box does not shift up into the highest gear until the engine has reached its maxi-
mum revolutions for this gear range. WARNING
Please note that using the kickdown function can result in the driven wheels
spinning on a smooth or slippery road surface - risk of skidding!
Dynamic shift programme The automatic gearbox of your vehicle is controlled electronically. Shifting up and
down through the gears is performed automatically on the basis of pre-defined
driving programmes.
Adopting a moderate style of driving
will cause the gearbox to select the most
economical driving programme. Shifting up into a higher gear as soon as possible
and shifting down as late as possible will have a favourable effect on your fuel
consumption.
Adopting a sporty style of driving with rapid movements of the accelerator pedal
combined with sharp acceleration and frequent changes in speed, exploiting the
top speed of the car or depressing the accelerator pedal (kickdown function), will
cause the gearbox to switch over to this style of driving and shift down earlier
with frequent changes in gears in comparison to the moderate style of driving.
Selecting the most appropriate driving programme for the particular style of driv-
ing is a continuous process. Irrespective of this it is, however, possible to switch or
shift down into a dynamic shift programme by depressing the accelerator rapidly.
The gearbox shifts down into a lower gear matching the speed of the car and this £1)
