Position
Move the steering wheel back and forward a little if the ignition key cannot, or cannot easily be turned into
this position, in order to
release the steering lock.
Position
The engine is started in this position. At
the same time switched on low beam or
main beam or other electrical compon
ents with major po
wer consumption are
briefly switched off. The ignition key moves back into position when one releases the key. The ignition key must be turned back into
position each time before starting the
engine again. The starter repeat lock in th
e ignition lock prevents the starter being
engaged when the engine is running and thus getting damaged. Ignition key withdrawal lock (automatic gearbox) You can only withdraw the ignition key after switching off the ignition if the selector lever is in position
P.
WARNING
•
When driving, the ignition key must always be in the position (igni-
tion switched on) without the engine running. This position is indicated by the warning lights coming on. If this is not the case, it could result in unex- pected locking of the steering wheel - risk of accident!•
Only remove the ignition key from the ignition lock when the vehicle has
come to a standstill (by applying the handbrake or moving the selector lever into the position P). The steering lock
can engage immediately - risk of acci-
dent!•
Always withdraw the ignition key if
you are going to leave the vehicle,
even for a short time. This is particularly
important if children are left in the
vehicle. The children might otherwise star
t the engine or switch on electrical
equipment (e.g. power windows) - risk of accident or injury!

Starting the engineGeneral You can only start the engine only using an original ignition key.•
Place the gearshift lever into neutral (or place the selector lever to the position
P or N in the case of an automatic gearbox)
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 ma
y 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 no
rmal and is not an operating problem.
If the engine does not start ... You can use the battery of anothe
r vehicle as a jump-start aid
⇒page 252.
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 256.
WARNING
•
Never run the engine in non ventilat
ed 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 uncon-
sciousness 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 i
mmediately 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 oper
ating temperature - risk of damaging the
engine!•
Vehicles which are fitted with an exhaus
t gas catalytic conver
ter 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 vehi
cle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the pollutant emissions are lower.Petrol enginesThese engines are fitted with a starter system which selects the correct fuel/air mixture for every external air temperature.•
Do not operate accelerator befo
re 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 258.
•
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 enginesGlow 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 temper-ature. The preglow indicator light

Starting the engine after the 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 posi-

WARNING
•
Never switch off the engine before the
vehicle is stationary - risk of acci-
dent!•
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.
Caution
you should not switch the engine off right
away at the end of yo
ur journey
after the
engine has been operated for a lengthy peri
od 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 conti
nue 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 temperature 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 225, “Working in the engine compartment”.
Shifting (manual gearbox)Shift into reverse only when the vehicle is
stationary. Depress the clutch pedal and
hold it fully depressed. Wait a moment be
fore engaging reverse gear in order to
avoid any shift noises.

people who wear such clothing are not recognised by the sensors of the parking aid.
Note
•
Only the front parking aid operates if you are towing a trailer (applies only to
models which feature a factory-fitted towing device*).•
If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your vehicle,
this indicates a system fault. The fault is
confirmed additionally
when the symbol flashes in the button
⇒page 128,
fig. 150
. Have the fault rectified by a specialist workshop.
•
The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.•
If the parking aid is activated and the se
lector lever of the automatic gearbox is
in the position , warning signal indicates interruption (vehicle can no longer move).Cruise control system (CCS)*IntroductionThe cruise control system (CCS) maintains a constant speed, more than 30 km/h (20 mph), once it has been set, without you
having to depress the accelerator pedal.
This is only possible within the range wh
ich is permitted by the power output and
braking power of the engine. The cruise co
ntrol system makes it possible - particu-
larly 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: Al
ways 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 gearbo
x to switch on the
cruise control system if the sele
ctor lever is in the position
P, N or R.
Storing a speedThe cruise control system is operat
ed by means of the switch and
rocker button in the left lever of the multi-functional switch. – Press the switch

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

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".

Technical Data
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

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 inter- rupted, 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 ot
herwise 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 225, “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 peda
l in order to move the selector lever out
of this position. The warning light
⇒page 37 lights up in the instrument cluster
as a reminder for the driver when
the selector lever is in position
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 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 th
e 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 select
or 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 acceleration power.Depressing the accelerator pedal allows th
e kickdown function to be activated in
the desired driving program. This function has precedence over the driving programme and serves for maximum accelera
tion 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 highes
t gear until the engine has reached its
maximum revolutions for this gear range.
WARNING
Please note that using the kickdown f
unction can result in
the driven wheels
spinning on a smooth or slippery road surface - risk of skidding!
