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 stationary with the gear engaged by means of the “acceler-
ator”, this means by letting the cl utch slip. This can lead to over-
heating of the clutch. If there is a risk of overheating of the clutch
due to overload, the clutch is opened automatically 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 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 result of this the vehicle can no longer be driven. If
the clutch opens automatically, depress the brake pedal, wait a few
seconds and only then continue driving.

lighted ⇒fig. 142 . In the positions D and S the gear you have engaged 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 depress the brake pedal.
If the battery is used, the selector lever cannot be moved out of the posi-
tion P ⇒ page 162.
R - Reverse
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
reverse 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.
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 R, with the ignition switched on, on a vehicle travelling at
less than 5 km/hour or on a stationary vehicle. D - Drive, 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 stationary.
In certain circumstances (e.g. when driving in mountainous regions or
when towing a trailer) it may be beneficial to select the manual shift
programme ⇒page 160 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 potential 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
maximum speed is achieved with the 5th gear.
The Shiftlock on the selector lever grip must be pressed when moving the
selector 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 (except P and N) since the power transmission
is never completely interrupted, also not when the engine is idling
- the vehicle "creeps".
•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 248,
“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 38 lights up
in the instrument cluster as a reminder for the driver when the selector
lever is in position P and N
In addition, the symbol
 for the automatic selector lever lock in the shift
gate lights up.
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 lever 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 - Ignition key withdrawal lock
You can only withdraw the ignition key after switching off the ignition if the
selector lever is in position
P. If the ignition key is withdrawn, the selector
lever is blocked in postion P.
Kickdown function
The kickdown function provides you with maximum accel-
eration power.
Depressing the accelerator pedal allows the kickdown function to be acti-
vated 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 current 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 gearbox does not shift
up into the highest gear until the engine has reached its maximum revolu-
tions 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 favour-
able effect on your fuel consumption.
Adopting a sporty style of driving with rapid movements of the acceler-
ator 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 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 matching the speed of the car and this allows you to accelerate
rapidly (e.g. when overtaking) without having to depress the accelerator
pedal fully into the kickdown range. The original programme will be reac-
tivated to match your particular 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.

Switching over to manual shifting
– Push the selector lever to the right out of position D. As soon
as the gearbox has switched over, 6 5 4 3 2 1 appears in the
display, with the gear engaged being highlighted ⇒page 160,
fig. 144.
Shifting up gears
– One-touch forward of the selector lever (in the Tiptronic posi- tion) ⇒page 160, fig. 143 .
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 in gears 1, 2, 3,
4 and 5 into the next higher gear just before the maximum permissible
engine speed is reached.
If you select a lower gear, the automatic gearbox does not shift down until
there is no risk of the engine overrevving. (Does not apply for the shifting
from 2nd to 1st gear.)
If you operate the kickdown function, the gearbox shifts into a lower gear
in line with the vehicle speed and engine speed.
Emergency programme
An emergency programme exists in the event of a fault in
the system.
The gearbox operates in a corresponding emergency programme if there
are functional 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 emer-
gency mode.
If the gearbox has switched over to emergency mode, drive to the
nearest specialist garage in order to have the fault rectified.

Front airbags
Description of the front airbags
The airbag system is not a substitute for the seat belt!
The front airbag for the driver is housed in the steering wheel ⇒fig. 161 .
The front airbag for the front passenger* is housed in the dash panel
above the storage compartment ⇒fig. 162 . The installation positions are
each marked with the “AIRBAG” logo.
The front airbag system, in combination with three-point safety belts,
offers additional protection for the head and chest area of the driver and
front passenger in the event of a frontal collision of major severity ⇒ in
“Important safety information regarding the front airbag system” on
page 194.
The airbag is not a substitute for the seat belt, but is part of the complete
passive vehicle safety concept. Please note that an airbag can only
offer you optimal protection in combination with a seat belt which is
fastened. .
Apart from their normal protective function, a further task of the seat belts
is to also hold the driver and front passenger in a correct seated position
in the event of a frontal collision so as to enable the front airbags to offer
the maximum protection.

Intelligent Technology
Electronic stability programme (ESP)*
General
General
The ESP aids you maintain control of your vehicle in situations in border-
line driving situations such as when negotiating a curve too fast. The risk
of skidding is reduced and your car 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),
•Driver-steering recommendation,
•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 indi-
vidual systems. It also processes additional measurement data which are
supplied by highly sensitive sensors: the rotational velocity of the vehicle
about its vertical axis, the lateral acceleration of the vehicle, the braking
pressure and the steering angle.
The direction which the driver wishes to take 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 exist, such as the
car 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 rear
wheel of a vehicle which tends to understeer (tendency to shift out of the
curve). This braking control cycle is accompanied by noises.

Intelligent Technology
214
The ESP operates in combination with the ABS ⇒page 218, “Antilock
brake system (ABS)”. If there is a fault in the ABS system, the ESP also
does not operate.
The ESP warning light ⇒page 40 lights up in the instrument cluster when
there is a fault on the ESP.
Switching off
You can switch the ESP off and on again as you wish, by pressing the
button ⇒page 213, fig. 180 . The ESP warning light ⇒page 40 lights up in
the instrument cluster when the ESP is switched off.
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 car free when it has become stuck
then you should switch on the ESP again.
WARNING
It is also not possible for the E SP 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 otherwise - 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
assignment of tyres and wheels) can influence the function of the ESP
⇒ page 270, “Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDL)*
The electronic differential lock prevents 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 conditions 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
process 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
