Automatic gearboxAutomatic gearbox*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

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 134,
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, howeve
r, 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, mo
ve 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 124. 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".

Information for driving with the automatic gearbox DSG* The abbreviation DSG means Direct shift gearbox (Direct shift gearbox). 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 trans-mission of the engine to the front wheels is not interrupted. Shifting up and down through the gears is perf
ormed 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

WARNING
•
Do not depress the accelerator when changing the position of the
selector lever if the car is stationary an
d the engine is running - risk of acci-
dent!•
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
stationary with the gear engaged by me
ans 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 clut
ch 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 gear
box DSG is equipped with an overload
protection. If you make use of
the uphill function on a vehi
cle which is stationary or
driving slowly uphill, it will result in an
increase of thermal stress of the clutches.
•
An overheating of the clutches can be detected by the flashing of the selector
level indicator and the “jerk” of the clutches, finally the clutches are opened. The power transmission from the engine to the front wheels is interrupted and as a

Seat belts
168
Seat beltsWhy seat belts?It is a proven fact that seat belt
s offer good protection in accidents
⇒fig. 169
. Thus
wearing a seat belt is a legal requirement in most countries. Seat belts which have been correctly fastened and adjusted hold the occupants of the car in the correc
t seated position
⇒fig. 169
. The belts reduce the kinetic energy
(energy of motion) to a considerable extent. They also prevent uncontrolled move-ments which, in turn, may well result in severe injuries. The occupants of a vehicle who have fastened
and correctly adjusted their seat belt,
profit to a major extent from the fact that
the kinetic energy is optimally absorbed
by the belts. The structure of the front end of the vehicle and other passive safety measures, such as the airbag system, also
contribute to reducing the kinetic energy.
The energy produced is thus absorbed and there is less risk of injury. Accident statistics prove that seat belts
which are fastened and properly adjusted
reduce the risk of an injury and enhance the chance of survival in a major accident ⇒ page 169.
It is important that you pay attention to
safety measures, particularly when trans-
porting children in the vehicle
⇒page 184, “What you should know about trans-
porting children!”.
WARNING
•
Fasten your seat belt each time before setting off, also when driving in
town! This also applies to the people seated at the rear - risk of injury!•
Expectant women must also always wear
a seat belt. This is the only way
of ensuring optimal protection for the unborn child
⇒page 170.
•
It is important for the belt webbing to
be properly routed if the seat belts
are to offer the maximum protection. You can see a description of how safety belts should be fitted pr
operly on the next pages.
Note
Please comply with any differing legal
requirements when using the seat belts.

Technical Data
The physical principle of a frontal collisionThe physical principle of a frontal a
ccident can be explained quite simply:
Motion energy, so-called kinetic energy, is
produced as soon as the vehicle is
moving, both for the vehicle and its occupants. The magnitude of this kinetic energy depends essentially on the speed at which the vehicle is travelling and on the weight of the vehicle and the occupants. The greater the speed and weight increase,
the greater the amount of energy which has to be absorbed in the event of an acci- dent. The speed of the vehicle is, nevertheless,
the most important factor. Doubling the
speed of the vehicle from 25 km/h up to
50 km/hour increases the kinetic energy
four times. The common opinion that it is possible to
support your body
in a minor accident
with your hands, is incorrect. Even in a
collision at only a low speed, the forces
acting on the body are such that it is
no longer possible to support your body.
Even if you only drive at a speed within the range from 30 km/hour to 50 km/hour, the forces which are produced on your body
in the event of an accident can easily
exceed 10.000 N (Newton). This equals a weight of one tonne (1 000 kg). In the event of a frontal collision, occupants of the car not wearing a seat belt, are thrown forward and strike in an uncontrolled way parts of the interior of the car, such as steering wheel, dash panel, windscreen,
⇒fig. 170
. The occupants of a
vehicle who have not fastened their seat belts may even be thrown out of the vehicle. This can resu
lt in fatal injuries.
It is also important that rear seat occupants fasten their seat belts as they will other- wise be thrown through the vehicle in an
uncontrolled manner in the event of an
accident A rear seat passenger who has not
fastened the seat belt is a danger not
only to himself but also fo
r those seated at the front
⇒fig. 171
.
Important safety information regarding the use of seat beltsThe correct use of the seat belts considerably reduces the risk of injury!
WARNING
•
The belt webbing must not be jammed in-between at any point or
twisted, or chafe ag
ainst any sharp edges.
•
It is important that the belt webbing is properly routed if the seat belts
are to offer their maximum protection

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral The ESP aids you maintain control of your vehicle in situations in borderline driving situations such as when negotiating a curve too fast. The risk of skidding is reduced and your vehicle thus offers greater driving stability depending on the conditions of the road surface. This occurs at all speeds. The following systems are integrated into the electronic stability programme:•
Electronic Differential Lock (EDL),
•
Traction control system (TCS),
•
Active driver-steering recommendation (DSR),
•
Antilock brake system (ABS),
•
Brake Assist,
•
Uphill-Start off-Assist.
Operating principle The ESP switches on automatically when the engine is started and then conducts a self-test. The ESP control unit processes data from the individual systems. It also processes additional measurement data which are supplied by highly sensitive sensors: the rotational velocity of the vehi
cle about its vertical axis, the lateral accel-
eration of the vehicle, the brakin
g pressure and the steering angle.
The direction which the driver wishes to ta
ke is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual behaviour of the vehicle. If differences exis
t, such as the vehicle beginning to skid,
the ESP will automatically brake the appropriate wheel. The car is stabilised again by the forces which take effect when the wheel is braked. Intervention into the brake system takes place primarily on the outer front wheel of a vehicle which tends to oversteer (tendency for the rear of the vehicle to break away) while occurs this is on the inner re
ar wheel of a vehicle which tends to under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied by noises. The ESP operates in combination with the ABS
⇒page 197, “Antilock brake system
(ABS)”. If there is a fault in the ABS system, the ESP also does not operate. The ESP warning light lights up in the instru
ment cluster when there is a fault on the
ESP
 ⇒page 37.
Switching off You can switch the ESP off and on again
as you wish, by pressing the button
⇒ fig. 196
. The ESP warning light lights up in th
e instrument cluster when the ESP is
switched off
 ⇒page 37.
The ESP should normally always be switched
on. It may be good practice in certain
exceptional cases, such as when you wish
to have wheel slip, to switch off the
system. Examples:

when driving with snow chains

when it is necessary to rock a vehicle 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 244,
“Accessories, changes and replacement of parts”.Electronic Differential Lock (EDL)* 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 driv
en 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
•
Carefully depress the accelerator when accelerating on uniformly slip-
pery road surfaces, such as ice and sn
ow. 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 vehicle 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

Traction control system (TCS) The traction control system prevents
the driven wheels from spinning
when accelerating.General The TCS 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 TCS switches on automatically when th
e engine is started and then conducts a
self-test. The system monitors the speeds of the driven wheels with the aid of the ABS sensors. If the wheels are spinning, the force transmitted to the road surface is automatically adapted by redu
cing the engine speed. Th
is occurs at all speeds.
The TCS operates in combination with the ABS
⇒page 197, “Antilock brake system
(ABS)”. The TCS will not function if a fault exists in the ABS system. The TCS warning light lights up in the instrument cluster when there is a fault on the TCS

Switching off You can switch the TCS off and on again
as you wish by pressing the button
⇒ fig. 197

pped with active driver-steering recommendation (DSR).
This function indicates to the driver in critical situations a steering recommendation in order to stabilise the vehicle. The active driver-steering recommendation is acti-vated, for example, on the right and left
vehicle side when
braking sharply on
different road surfaces.

rated when the engine is running.
WARNING
•
Never switch off the engine before the vehicle is stationary.
•
The brake booster only operates when the engine is running. Greater
physical effort for braking is required
when engine is switched off. Because
if you do not stop as normal, this can cause an accident and severe injuries.Antilock brake system (ABS)ABS prevents the wheels locking when braking.General The ABS contributes significan
tly to enhancing the active
safety of your vehicle.
Compared to a vehicle not fitted with the ABS brake system, you are able to retain optimal steering ability even during a fu
ll brake application on a slippery road
surface because the wheels do not lock up. You must not expect, however, that the br
aking distance will be shorter under all
circumstances as a result of the ABS. Th
e braking distance for example on gravel
and fresh snow, when you should anyway be driving slowly and cautiously, will be longer. Operating principle The brake pressure will be reduced on a wheel which is rotating at a speed which is too low for the speed of the vehicle and tend
ing to lock. This control cycle is notice-
able from a
pulsating movement of the brake pedal
which is accompanied by
noises. This is consciously intended to provide the driver with the information that the wheels are tending to lock (ABS control range). You must always keep the brake pedal depressed to enable the ABS to optima
lly control the brake application in this
braking range. Never interrupt the application of the brakes!
WARNING
•
The ABS can also not overcome the physic
al limits of your vehicle. Please
do not forget this, particularly when driv
ing on icy or wet road surfaces. If the
ABS is operating within the control ra
nge, adapt your speed immediately to
the conditions of the road surface and the traffic situation. The increased safety offered by the ABS must not tempt you to take greater risks than otherwise - risk of an accident!•
The normal braking system is still fully
functional if there is an ABS fault.
Visit a specialist garage as quickly as po
ssible and adjust yo
ur style of driving
to take account of the ABS fault in the meantime since you will not know how great the damage is.
