WARNING
•When driving, the ignition key must always be in the position
(ignition switched on) without the en gine running. This position is
indicated by the warning lights coming on. If this is not the case, it
could result in unexpected locking of the steering wheel - risk of
accident!
•Do not withdraw the ignition key from the lock until the car has
come to a stop. The steering lock can engage immediately - risk of
accident!
•Always withdraw the ignition key if you are going to leave the
vehicle, even for a short time. This is particularly important if chil-
dren are left in the vehicle. The children might otherwise start the
engine or operate electrical equi pment (e.g. power windows) - risk
of injury!
Starting the engine
General
You can only start the engine only using an original ignition
key.
•Place the gearshift lever into neutral and put on the handbrake firmly
before starting the engine.
•The clutch pedal should be fully depressed when starting the engine
which means that the starter only has to crank the engine.
•Let go of the key as soon as the engine starts otherwise there may be
damage to the starter. The engine running noises may louder at first be louder for a short time
after starting the cold engine until oil pressure can be built up in the
hydraulic valve clearance compensation. This is quite normal and is not
an operating problem.
If the engine does not start ...
You can use the battery of another vehicle as a jump-start aid
⇒
page 243.
It is only possible to tow-start vehicles fitted with a manual gearbox. The
tow-starting distance must not be more than 50 metres ⇒page 247.
WARNING
•Never run the engine in non ventilated or enclosed areas. The
exhaust gases of the engine contain besides the odorless and
colourless carbon monoxide a poisonous gas - hazard! Carbon
monoxide can cause unconsciousness and death.
•Never leave your vehicle unattended with the engine running.
Caution
•The starter may only be operated (ignition key position ), if the
engine is not running. If the starter is immediately operated after switching
off the engine, the starter or the engine can be damaged.
•Avoid high engine revolutions, full throttle and high engine loads as
long as the engine has not yet reached its normal operating temperature
- risk of damaging the engine!
•Vehicles which are fitted with an exhaust gas catalytic converter
should not be tow-started over a distance of more than 50 metres.

For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right
away. When driving the engine reaches its operating temperature more
rapidly and the pollutant emissions are lower.
Petrol engines
These engines are fitted with a starter system which selects the correct
fuel/air mixture for every external air temperature.
•Do not operate accelerator before and when starting engine.
•Interrupt the attempt at starting after 10 seconds if the engine does not
start right awayand wait for about 30 seconds before repeating the
attempt.
•It is possible that the fuse on the electrical fuel pump is defect if the
engine still does not start. Check the fuse and replace it if necessary
⇒ page 249.
•If the engine does not start, contact the nearest specialist garage to
obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the
accelerator after the engine has started.
Diesel engines
Glow plug system
Diesel engines are equipped with a glow plug system, the preglow period
being controlled automatically in line with the coolant temperature and
outside temperature. The preglow indicator light
comes on after the ignition has been
switched on.
You should not switch on any major electrical components during
the heating period otherwise the vehicle battery will be drained
unnecessarily.
•You should start the engine immediately after the glow plug warning
light has gone out.
•The glow plug warning light will come on for about one second if the
engine is at a normal operating temperature or if the outside temperature
is above +5°C. This means that you can start the engine right away.
•Interrupt the attempt at starting after 10 seconds if the engine does not
start right awayand wait for about 30 seconds before repeating the
attempt.
•It is possible that the fuse on the diesel preglow system is defect if the
engine still does not start. Check the fuse and replace it if necessary
⇒ page 249.
•Contact the nearest specialist garage to obtain professional assist-
ance.
Starting the engine after fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel
tank has run completely dry - up to one minute. This is because the fuel
system must first of all be filled while the attempting to start the engine.
Switching off the engine
– The engine can be switched off by turning the ignition key from position ⇒page 110, fig. 100 into position .

WARNING
•Never switch off the engine before the vehicle is stationary - risk
of accident!
•The brake booster only operates when the engine is running.
Greater physical effort for brakin g is required when engine is
switched off. Because if you do not stop as normal, this can cause
an accident and severe injuries.
Caution
you should not switch the engine off right away at the end of your journey
after the engine has been operated for a lengthy period at high loads but
should be allowed it to run at idling speed for about 2 minutes. This
prevents any accumulation of heat when the engine is switched off.
Note
•The radiator fan may continue running for a further 10 minutes or so
after the engine and the ignition have been switched off. The coolant fan
may, however, also switch on again after some time if the coolant temper-
ature rises because of an accumulation of heat in the engine or if the
engine is warm and the engine compartment is additionally heated by
strong sunlight.
•This is why particular care is required when carrying out any work in
the engine compartment ⇒page 210, “Working in the engine
compartment”.
Shifting (manual gearbox)
Shift into reverse only when the car is stationary. Depress the clutch pedal
and hold it fully depressed. Wait a moment before engaging reverse gear
in order to avoid any shift noises.
The reversing lights will come on once reverse gear is engaged, provided
the ignition is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
•One should not lay the hand on the shift lever while driving the vehicle.
The pressure of the hand will be transferred to the gearshift forks in the
gearbox. This can, over a period of time, lead to early wear of the gearshift
forks.

Cruise control system (CCS)*
Introduction
The cruise control system (CCS) maintains a constant speed, more than
30 km/h, once it has been set, without you having to depress the acceler-
ator pedal. This is only possible within the range which is permitted by the
power output and braking power of the engine. The cruise control system
makes it possible - particularly 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: Always 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 selector lever is in the position P, N or
R .
Storing a speed
The cruise control system is operated by means of the slide
switch and rocker button in the left lever of the multi-func-
tional switch.
– Press the switch ⇒fig. 104 into the position ON.
– After the desired speed has been reached, press the rocker button into the SET position - the current speed is stored.
After you have released the rocker button out of the position SET, the
speed you have just stored is maintained at a constant speed without
having to depress the accelerator.
Yo u c a n increase the speed by depressing the accelerator. Releasing the
accelerator will cause the speed to drop again to the set speed.
This does not apply, however, if you drive at a speed which is more than
10 km/h higher than the set speed for a period of longer than 5 minutes.

Automatic gearbox
6-speed automatic gearbox*
Introduction
Your car is equipped with an electronically controlled 6-speed automatic
gearbox. Shifting up and also down through the gears is performed auto-
matically.
At the same time this is a conventional 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.
Information for driving wi th an automatic gearbox
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 123.
Starting-off and Driving
– Depress the brake pedal and hold 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 120, and then release the Shiftlock button. – Wait a moment until the gearbox has shifted (a slight engage-
ment 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 stopping just for a short time, such as at a cross roads.
It is sufficient to hold the vehicle stationary using 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 ⇒ p a g e 111 .
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 while driving it is first
necessary to release pressure on the accelerator 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 accident!
•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".
Selector lever positionsThe selector lever position you have engaged is shown in the information
display of the instrument cluster with the corresponding gear symbol high-
lighted ⇒fig. 106 . In the positions D and S the gear you have already
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 124.
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 123 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 210,
“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

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 position 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
