Selector lever positionsFig. 117 Selector lever / informatio n display: Selector lever positionsThe current selector lever position is indica ted in the information display of the instru-
ment cluster fig. 117 - right. In the positions D and S the gear you have already
engaged will be additionally displayed on the display.
- Parklock
The driven wheels are locked mechanically in this position.
The Parklock must only be engage d 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 select or lever and at the same time depress the
brake pedal.
If the battery is used, the selector lever cannot be moved out of the position P.
- 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 an d the selector lever is in position R, the reverse
lights will come on.
- Neutral
The transmission is in Neutral in this position. The brake pedal must be depressed (if the le
ver is in its position for longer than 2
seconds) in order to move the se lector lever out of the position N into the position D
or R, with the ignition switched on, on a vehicl e travelling at less than 5 km/hour or on
a stationary vehicle.
- 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 into position D from N when the
vehicle is travelling at less th an 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 120 for a
short time in order to adapt the gearbox ratios manually to the driving situations.
- 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 posi-
tion D.
The gearbox does not shift into the 6th gear in the position S, because the maximum
speed is reached with the 5th gear
11).
The Shiftlock on the selector lever grip mu st 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 vehi cle 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 driv e 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 hand-
brake 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 197, “Working in the engine compartment”.
Selector lever lockAutomatic 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 or der to move the selector lever out of this
position. The warning light
page 33 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 lo ck 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 swit ched off automatically into position N when the
car is travelling at a higher speed.
Shiftlock button
The Shiftlock button in the hand le of selector lever prevents certain selector lever posi-
tions 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
position P.
Kickdown function
The kickdown function provides you with maximum acceleration
power.Fully depressing the a ccelerator pedal allows the kickdown function to be activated in
the desired driving program. This function has precedence over the driving
programme and serves for maximum accelerati on of the vehicle when exploiting the
maximum power potential of the engine wi thout 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 en gine has reached its maximum 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 programmeThe 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 po ssible will have a favourable effect on your fuel consump-
tion.
Adopting a sporty style of driving with rapid movements of the accelerator pedal
combined with sharp acceleration and freque nt changes in speed, exploiting the top
speed of the car or depressing the accele rator 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 depressi ng 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 reactivated to
match your particular styl e 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 an d 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.Fig. 118 Selector lever: manual shifting / information display: manual shiftingThe selector lever position you have engaged is indicated in the information display of
the instrument cluster together with the engaged gear fig. 118 - right.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) fig. 118 .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 gearbox does not shift down until there is no
risk of the engine overrevving.
If you operate the kickdown function, the gear box shifts into a lower gear in line with
the vehicle speed and engine speed.

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 switch ed over to emergency mode, drive to the nearest
specialist garage in order to have the fault rectified.
Selector lever-emergency unlockingIn case of interruption of the power supply (e .g. flat vehicle battery, defective fuse) or
defect of the selector lever lock, the selector lever can no longer be shifted from the
position P in the normal way and the vehicle ca n no longer be moved. The selector
lever must be unlocked in case of emergency.
– Apply the handbrake firmly. – Open the storage compartment in front centre console* or the front ashtray.
– Carefully pull up the front left and right cover.
– Pull up rear cover.
– Use a finger to press the yellow pl

BrakesWhat has a negative effect on braking efficiency?Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating conditions of
the vehicle and your style of driving. Particul arly if you drive a great deal in towns and
over short distances or if you adopt a sporty style of driving, it may be necessary to
have the thickness of the brake pads inspected at a specialist garage between the
service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under certain conditions
such as when driving through water, during heavy rain showers or after the vehicle has
been washed in an automatic vehicle wash , since the brake discs and brake pads may
be moist or even have a coatin g of ice on them in winter. Yo u s h o u l d d r y t h e b r a k e s a s
soon as possible by applying and releasing the brakes several times.
There also may be a certain delay before the full braking efficiency is available when
driving on roads which have been treated with road salt if you have not used the brakes
for some considerable time beforehand. The layer of salt on the brake discs and brake
pads must first be rubbed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on th e bake pads occur if the vehicle has been
parked for a long period an d if you do not make much use of the braking system.
We recommend cleaning the brak e discs by firmly applying the brakes at a fairly high
speed if you do not make much use of the braking system or if surface corrosion is
present .
Faults in the brake surface
If you notice that the braking distance ha s suddenly become longer and that the brake
pedal can be depressed further, it is possible that a brake circuit of the dual-circuit
brake system has failed. Drive, in such cases, to the nearest specialist garage without
delay in order to have the problem rectified. Drive at a reduced speed while on your
way to the dealer and adapt your style of driving to the higher brake pedal pressure
required. Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The level
of the brake fluid is monitored electronically
page 34, “Brake system ”.
WARNING
Only apply the brakes for the purpose of drying and cleaning the brake discs
if the traffic conditions permit this. Do not place any other road users in jeop-
ardy.
When retrospectively mounting a front spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced other-
wise the braking system could run too hot.
Allow for the fact that new brake pads do not achieve their full braking effi-
ciency until approximately 200 kilometres. New brake pads must be first “run
in” before they develop their optimal fric tion force. You can, however, compen-
sate for this slightly reduced braking fo rce by increasing the pressure on the
brake pedal. This guideline also applie s to any new brake pads installed at a
future date.Caution
Never allow the brakes to rub by applying sl ight pressure if you do not wish to brake
the vehicle. This causes the br akes to overheat and can also result in a longer braking
distance and excessive wear.
Before negotiating a steep downhill section, please reduce your speed, shift down
into the next lower gear (manual gearbox) or select a lower driving stage (automatic
gearbox). This enables you to make full us e of the braking power of the vehicle and
reduces the strain on the brakes. Any additional braking should be done intermittently,
not continuously.Note
The brake light flashes automatically in case of an emergency braking at speeds greater
than 60 km/h or with the intervention of th e ABS, which lasts longer than 1.5 seconds.
After the speed was reduced below 10 km/h or the vehicle was stopped, the brake light
stops flashing and the hazard warning light system switches on. The hazard warning
light system is switched of f automatically after accelerating or driving off again.

Driving and the EnvironmentThe first 1 500 kilometres and then afterwardsA new engine
The engine has to be run in during the first 1 500 kilometres.Up to 1 000 kilometres– Do not drive faster than 3/4 of the maximum speed of the gear in use, that is 3/4 of
the maximum permissi ble engine speed.
– Do not use full throttle.
– Avoid high engine revolutions.
– Do not tow a trailer.From 1 000 up to 1 500 kilometres– Increase the power output of the engine gradually up to the full speed of the gear
engaged, that is up to the maxi mum permissible engine revolutions.
During the first operating hours the engine ha s higher internal friction than later until
all of the moving parts have harmonized. Th e driving style which you adopt during the
first approx.1 500 kilometres plays a decisive part in the success of running in your
vehicle.
You should not drive at unnecessarily high engine revolutions even after the
running-in period is complete . The maximum permissible en gine speed is marked by
the beginning of the red zone on the scale of the revolutions counter. Shift up into the
next higher gear on a vehi cle fitted with manual gear box before the red zone is
reached. Extremely high engine revolutions are automatically governed, by the way.
For a vehicle fitted with a manual gearbox the converse situation also applies: Do not
drive at engine revolutions which are too low. Shift down as soon as the engine is no
longer running smoothly.
Caution
All the speed and engine revolution figures ap ply only when the engine is at its normal
operating temperature. Never rev up an engine which is cold, neither when the vehicle
is stationary nor when driving in individual gears.
For the sake of the environment
Not driving at unnecessari ly high engine revolutions and shifting to a higher gear as
early as possible are ways to minimise fu el consumption and operating noise levels
and protects the environment.New tyresNew tyres have to be “run in” since they do not offer optimal grip at first. You should
take account of this fact for the first 500 kilometres and drive particularly carefully.New brake padsAllow for the fact that new brake pads do no t achieve their full braking efficiency until
approximately 200 kilometres. New brake pads must be first “run in” before they
develop their optimal friction force. You ca n, however, compensate for this slightly
reduced braking force by increasing the pressure on the brake pedal.
This guideline also applies to any new brake pads installed at a future date.
During the running-in pe riod, you should avoid excessive stresses on the brakes. This
includes, for example, violent braking, part icularly from very high speeds, and also
when crossing mountain passes.

guidelines given in this chapter in order to
make best use of these characteristics and
to maintain their effectiveness.
The optimal engine speed should be obtained when accelerating, in order to avoid a
high fuel consumption and resonance of the vehicle.
Looking ahead when driving
A vehicle's highest fuel consumption occurs it accelerates.Avoid accelerating and braking unnecessarily. If you drive with forsight you will not
need to brake so often and will also then not have to accelerate so much. Let your
vehicle coast to a stop, for example, if this is possible, when you see that the next set of
traffic lights is at red.Shifting gears and saving energy
Shifting up early saves on fuel.Manual gearbox– Drive no more than about one length of your vehicle in first gear.
– Always shift up into the next higher gear at approx. 2 000 to 2 500 revs.Automatic gearbox– Depress the accelerator pedal slowly. Do not depress it beyond the kickdown
position, however. An effective way of achieving good fuel economy is to shift up
early. You will consume
more fuel if you drive at unnecessaril y high revolutions in any given gear.
The fig. 153 shows the ratio of fuel consumption to the speed of your vehicle in the
relevant gears. Fuel consumptio n in 1st gear is the highest, while that in 5th or 6th gear
is the lowest.
Only depress the accelerator pedal slowly if your vehicle is fitted with an automatic
gearbox in order to automatically select an economic driving programme. You will
achieve good fuel economy by shifting up early and shifting down late.
Note
Also use the information supplied by the multi-functional indicator* page 19.Avoiding full throttle
Driving more slowly means saving fuel.Sensitive use of the accelerator will not only significantly reduce fuel consumption but
also positively influence environmenta l pollution and wear of your vehicle.
You should avoid exploiting the top speed of your vehicle wherever possible. Fuel
consumption, pollutant emissions and vehicl e noises increase disproportionally at
high speeds.
The fig. 154 shows the ratio of fuel consumption to the speed of your vehicle. You
will cut your fuel consumption by half if you only make use three-quarters of the
possible top speed of your vehicle.

Driving through bodies of water on roadsIn order to avoid damage to the vehicle wh en driving through bodies of water (e.g.
flooded roads), observe the following:
Determine the depth of the water when driv ing through bodies of water. The water
can reach at the maximum the web on the lower sill of the vehicle fig. 156 .
Drive no more than at walking speed. At a higher speed, a water wave can form in
front of the vehicle which can cause water to penetrate into the air induction system of
the engine or into other parts of the vehicle.
Never let the vehicle stand in the water, never drive backwards and do not switch
off the engine.
WARNING
Driving through water, mud, sludge etc. can reduce the braking power and
extend the braking distance - risk of accident!
Avoid sudden and severe braking manoeuvres immediately after driving
through bodies of water.
After driving through bodies of water, the brakes must be cleaned and dried
as soon as possible by intermittent braking. Only apply the brakes for the
purpose of drying and cleaning the brake discs if the traffic conditions permit
this. Do not place any other road users in jeopardy.
Caution
When driving through bodies of water, pa rts of the vehicle such as the engine,
gearbox, catalytic converter, chassis or electrics can be severely damaged.
Oncoming vehicles can generate water waves which can exceed the permissible
water level for your vehicle.
Potholes, mud or rocks can be hidden under the water making it difficult or impos-
sible to drive through the body of water.
Do not drive through salt water. The salt can lead to corrosion. Immediately rinse
all the parts of the vehicle, which came into contact with the salt water, with fresh
water.Note
After driving through a body of water, we recommend that the vehicle is checked by a
specialist garage.
