Automatic gearbox
136
Dynamic shift programmeThe 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 freq
uent 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 ge
arbox 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 ⇒

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

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 ha
ve 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 are the airbags deployed?The airbag system is designed in such
a way that the driver and front passenger
airbag are deployed in the event of a
frontal collision
of major severity.
In the case of a
violent side crash
, the side airbag* on the side on which the colli-
sion occurs, is depl
oyed together with the head airbag*.
In certain accident situa
tions, the front airbags, side airbags as well as the relevant
head airbag may be
deployed together.
The airbags
are not deployed
in the case of
minor
frontal and side collisions, in the
case of rear-end collisi
ons and vehicle rollover.
Deployment factors It is not possible to state globally which
deployment conditions apply to the airbag
system in every situation as the circumstances which exist in the case of accidents vary greatly. An important role in this case
, for example, is played by factors such as
the type of object (hard, soft) against whic
h the vehicle impacts or the type of object
against which the vehicle impa
cts, the angle of impact,
the relative vehicle speed
during the accident etc. A decisive factor for the deployment of the airbags is the deceleration which occurs during a collision. The control unit analyses
the nature of the collision and activates
the relevant restraint system. If the vehi
cle deceleration which occurs and is meas-
ured during the collision remains below the prescribed reference values specified in the control unit, the airbags are not
deployed although the vehicle may well
suffer severe damage to the bodywork
as a consequence of the accident.
The airbags are not deployed if:•
ignition off,
•
a minor frontal collision,
•
a minor side collision,
•
a rear-end collision,
•
Rollover of the vehicle.
Note
•
A grey white, non harmful gas is released when airbag is inflated. This is
perfectly normal and is not an indi
cation of a fire in the vehicle.
•
In the event of an accident in which the airbags are deployed: − The interior lighting comes on (if the switch for the interior light is in the door contact position), − The hazard warning light is switched on, − All the doors are unlocked, − the fuel supply to the engine is interrupted.

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 driving in deep snow or on a loose surface
•
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.•

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

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

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.

Brake Assist*During a severe brake application (e.g. if a hazard exists), the Brake Assist increases the braking force and thus makes it possible to rapidly produce the pressure required in the brake system. The majority of drivers do
apply the brakes in good time in dangerous situations,
but do not depress the brake pedal with su
fficient pressure. Consequently, it is not
possible for the vehicle to achieve its maximum deceleration and the vehicle covers a greater distance than necessary. The Brake Assist is activated by the very quick operation of the brake pedal. In such cases, a much greater braking pressure ex
ists than during a normal brake applica-
tion. This makes it possible, even with a relatively low resistance of the brake pedal, to produce an adequate pressure in the brake system in the shortest possible time, which is required for maximum deceleration of the vehicle. You must apply the brake pedal firmly and hold it in this po
sition in order to achieve the shortest
possible braking distance. The Brake Assist is able to help you achieve a shorter braking distance in emergency situations by rapidly producing the pressure
required in the brake system. It fully
exploits the attributes of the ABS. After you release the brake pedal, the function of the Brake Assist is automatically switched off and the brakes operate in the normal way. The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist function is also not available.
Further information on the ESP
⇒page 193.
WARNING
•
The Brake Assist is also not able to overcome the physical limits of your
vehicle in terms of the braking distance required.•
Adapt your speed to the conditions of the road surface and to the traffic
situation.•
The increased safety offered by the Brake Assist must not tempt you to
take a greater safety risk than otherwise.
Uphill-Start
off-Assist*
The uphill-start off-assist makes it much easier to start off on steep hills. The system assists a start off by holding the brake pr
essure produced by the brake pedal actu-
ation for approx. 2 seconds after releasing the brake pedal. The driver can therefore move his foot from the brake pedal to th
e accelerator pedal and start off on the
slope, without having to actuate the hand
brake. The brake pressure drops gradually
the more you operate the accelerator pedal. If the vehicle does not start off within 2 seconds, it starts to roll back. The uphill-start off-assist is active in the ev
ent of a 5% slope, if the vehicle door is
closed. It is alwa
ys active on slopes when in forward or reverse start off. When
driving downhill, it is inactive.Electromechanical power steeringThe power steering enables you to steer
the vehicle with le
ss physical force.
With the electromechanical power steering, the steering assist is automatically adapted to the speed and to the steering angle. It is still possible to fully steer the vehicle if the power steering fails or if the engine is not running (vehicle being towed in). The
only difference is that greater physical
effort is required. If there is a fault in the power steering, the warning light
 or  lights up in the
instrument cluster
⇒page 35.
WARNING
Contact your specialist
garage if the power steering is defective.
