Rear parking aid*
The parking aid provides a warning of obstacles behind the vehicle.
The audible parking aid determines the distance between the rear bumper and an
obstacle located behind the vehicle with the aid of ultrasound sensors. The tones
of the parking aid can be adapted in the menu of the information display*
⇒ page 30. The sensors are integrated in the rear bumper.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle (area
⇒ fig. 149 ). The interval between the warning signals becomes shorter as the
clearance is reduced.
A continuous tone sounds from a clearanc e of just 30 cm (Bereich ) - danger
area. You should not reverse any further after this signal sounds! If the vehicle
is equipped with a factory-fi tted towing device*, the border of the danger area
starts - continuous tone - 5 cm further behind the vehicle. The vehicle can be
extended through an installe d detachable towing device.
On vehicles equipped with a factory-fitted radio* or navigation*, the distance to the
obstruction is shown graphically on the disp lay. On vehicles with a factory-fitted
towing device, the sensors are deactivated when towing a trailer. The driver is also
informed of the radio* or the navigation* by a graphic display (vehicle towing a
trailer) on the display. The radio* or navi gation*, which is factory-fitted, can be set
so that the play function volume decrea ses when activating the parking aid, see Owner's Manual radio* or navigation*. This improves the audibility of the parking
aid.
Activating
The parking aid is activated automatically when
reverse gear is engaged and the
ignition is turned on. This is conf irmed by a brief acknowledgement signal.
Deactivating
The parking aid is deactivated by removing the reverse gear.
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
vehicle or carrying ou t similar manoeuvres.
•You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin po st, trailer drawbar etc., behind your
vehicle. 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
parking aid.
Note
•The parking aid does not operate if you are towing a trailer (applies to models
which feature a factory-fi tted towing device*).
•If a warning signal sounds for about 3 seconds after switching the ignition on
and engaging reverse gear, and there is no obstacle close to your car, this indicates
a system fault. 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.

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 output and
braking power of the engine. The cruise co ntrol system makes it possible - particu-
larly on long journeys - for you to rest your “accelerator foot”.
WARNING
•The cruise control system must not, for safety reasons, be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads or
loose chippings) - 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: Al ways 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 driving
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 sele ctor lever is in the position P, N or R.
Storing a speed
The cruise control system is operat ed by means of the switch and
rocker button in the left lever of the multi-functional switch.
– Press the switch ⇒fig. 152 into the position ON.

Information for driving with the 6-speed automatic gearbox*
Your car is equipped with a conventional 6-speed automatic
gearbox.
The maximum speed is reached in the 5th gear. The 6th gear serves as an
economic driving programme, which is intended to reduce the fuel
consumption. Shifting up and down through the gears is performed auto-
matically. 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 138.
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 136,
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 ⇒.
Stopping for a short time
– The selector lever position N does not have to be selected when stop-
ping just for a short time, such as at a cross roads. It is absolutely suffi-
cient to hold the stopped vehicle st ationary by depressing 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
⇒ page 126.
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 position N is selected by accident wh ile driving it is first neces-
sary to release pressure on the accelerato r 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 acci-
dent!
•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
(except P and N) since the power transmission is never completely inter-
rupted, also not when the engine is idling - the vehicle "creeps".

Automatic gearbox
138
Dynamic shift programme
The automatic gearbox of your vehicle is controlled electronically. Shifting up and
down through the gears is performed auto matically 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 a ccelerator 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 driving
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 matc hing the speed of the car and this allows
you to accelerate rapidly (e.g. when ov ertaking) without having to depress the
accelerator pedal fully into the kickdown range. The original programme will be
reactivated to match your part icular style of driving once the gearbox has shifted up
again.
When driving in hilly regions, the gears are selected to match uphill and downhill
sections. This avoids the gearbox frequently shifting up and down when negotiating
an uphill stretch. When driving downhill, it is possible to shift down into the
Tiptronic position, in order to exploit the engine brake torque.
Tiptronic
The Tiptronic allows the driver to also shift gears manually.
The selector lever position you have engaged is indicated in the informa-
tion display of the instrument cluster together with the engaged gear
⇒fig. 156 .
Switching over to manual shifting
– Push the selector lever to the right out of position D. After switching
over, the current engaged gear is indicated in the display.

Shifting up gears
– One-touch forward of the selector lever (in the Tiptronic position)
⇒page 138, fig. 155 .
Shifting down gears
– One-touch back of the selector lever (in the Tiptronic position) .
It is possible to switch over to manual both when the car is stationary and also when
driving.
When you accelerate, the gearbox shifts up automatically into the higher gear just
before the maximum permissible engine speed is reached.
If you select a lower gear, the automatic ge arbox does not shift down until there is
no risk of the engine overrevving.
If you operate the kickdown function, the ge arbox shifts into a lower gear in line
with the vehicle speed and engine speed.
Manual shifting on the multifunction steering wheel*
Switching over to manual shifting
– Push the selector lever to the right out of position D. After switching
over, the current engaged gear is indicated in the display. Shifting up gears
– Press the right rocker switch
⇒fig. 157 for the multifunction
steering wheel.
Shifting down gears
– Press the left rocker switch ⇒fig. 157 for the multifunction
steering wheel.
Temporarily switching over to manual shifting
– If the selector lever is in position D or S, press the left rocker switch
or the right rocker switch fo r the multifunction steering wheel.
– If the rocker switches or are not pressed for some time, the manual shifting switches off. You can also switch off the temporary
switch over to manual shifting by pressing the right rocker switch
for more than 1 second.
Emergency programme
An emergency programme exists in th e event of a fault in the system.
The gearbox operates in a corresponding emergency programme if there are func-
tional faults in the gearbox electronics. This is indicated by all of the segments in the
display lighting up or going out.
A functional fault can have the following effect:
•The gearbox only shifts into certain gears.
•The reverse gear R cannot be used.
•The manual shift programme (Tiptronic) is switched off in the emergency mode.
If the gearbox has switched over to emergency mode, drive to the nearest
specialist garage in order to have the fault rectified.

•when it is necessary to rock a ca r free when it has become stuck.
then you should switch on the ESP again.
WARNING
It is also not possible for the ESP to overcome the physical limits of the
vehicle. Even if a vehicle fitted with ESP you should still always adapt your
style of driving to the condition of the road surface and the traffic situation.
This particularly applies when driving on slippery and wet roads. The
increased safety offered must not tempt you to take greater risks than other-
wise - risk of an accident!
Note
•All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the ESP. Differing rolling circumferences of the tyres can lead to an
undesirable reduction in the engine output.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign-
ment of tyres and wheels) can influence the function of the ESP ⇒page 243,
“Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDS)*
The electronic differential lock pr events an individual wheel from
slipping.
Models fitted with ESP are equipped with electronic differential lock (EDL).
General
The EDL makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditio ns of the road surface are unfavourable. Operating principle
The EDL is activated automatically, that is without any action on the part of the
driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors.
Should only
one drive wheel begin spinning on a slippery surface there will be an
appreciable difference in the speed of the driven wheels. The EDL function brakes
the slipping wheel and the differential transmits a greater driving force to the other
driven wheel. This control proces s is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unusually severe stresses exist in order to
avoid excessive heat generation in the disc brake on the wheel which is being
braked. The vehicle can continue to be driven and has the same characteristics as a
vehicle not fitted with EDL.
The EDL switches on again automatically as soon as the brake has cooled down.
WARNING
•Depress the accelerator carefully when accelerating on uniformly slip-
pery road surfaces, such as ice and snow. The driven wheels might still spin
despite the EDL and affect the stability of the vehicle - risk of an accident!
•You should always adapt your style of driving to the condition of road
surface and to the traffic situation even when your vehicle is fitted with EDL.
The increased safety offered must not tempt you to take greater risks than
otherwise - risk of an accident!
Note
•If the ABS or ESP warning light comes on, this may also indicate a fault in the
EDL. Please have the car inspected as soon as possible by a specialist garage.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign-
ment of tyres and wheels) can in fluence the function of the EDL ⇒page 243,
“Accessories, changes and replacement of parts”.
