WARNING
•
You must not adjust the steering wheel when the vehicle is moving!
•
The driver must maintain a distance of
at least 25 cm to
the steering wheel
⇒ fig. 113
. Not maintaining this minimum distance will mean that the airbag
system will not be able to properly protect you - hazard!•
For safety reasons the lever must always be firmly pushed up to avoid the
steering wheel altering its po
sition unintentionally when driving - risk of acci-
dent!
•
If you adjust the steering wheel furthe
r towards the head, you will reduce
the protection offered by the driver airbag in the event of an accident. Check that the steering wheel is
aligned to the chest.
•
When driving, hold the steering wheel
with both hands firmly on the outer
edge in the 9 o'clock and 3 o'clock po
sition. Never hold the steering wheel
firmly in the 12 o'clock position or in another way (e.g. in the middle of the steering wheel or at the inne
r steering wheel edge). In such
cases, injuries to the
arms, the hands and the head can occur
when the driver airbag is deployed.

To lock the steering
, with the ignition key withdrawn, turn the steering wheel until the
steering locking pin is heard to
engage. You should always lock the steering as a general
rule if you leave your vehicle. This acts as
a deterrent against possible theft of your
vehicle
⇒
.
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, major electrical components are switched off for short periods. The igni
tion 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 r
unning 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 (ignition
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 unexpected locking of the steering wh
eel - 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 imme
diately - risk of acci-
dent!
•
Always withdraw the ignition key if yo
u 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 start the engi
ne or switch on el
ectrical 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 - the starter
then 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 anothe
r vehicle as a jump-start aid
⇒page 229.
It is only possible to tow-start vehicles fi
tted with a manual gearbox. The tow-starting
distance must not be more than 50 metres
⇒page 231.
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 mono
xide can cause unconsciousness and
death.

Never leave your vehicle unattended with the engine running.Caution
•
The starter may only be operated (ignitio
n key position ), if the engine is not
running. If the starter is immedi
ately operated after switchin
g 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 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. Through
this the engine reaches its operating temperature more rapidly and the pollutant emis- sions 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 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 electric
al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary
⇒page 233.
•
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 tempera-
ture. 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
.

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 turnin

appears in the display* if you have inad-
vertently driven off with the handbrake applied:
Handbrake on
The handbrake warning is acti
vated if you drive at a speed of more than 6 km/h for
more than 3 seconds.
WARNING
•
Please note that the handbrake must be fully released. A handbrake which
is only partially released can result in the rear brakes overheating which will have a negative effect on the operation of
the brake system - risk of accident! In
addition this can result in premature wear of the rear brake pads.•
Never leave children unattended in the vehicle. The children might, for
example, release the handbrake or take
the vehicle out of gear. The vehicle
might then move off - risk of accident!
Caution
After the car has come to a stop, always firs
t of all apply the handbrake firmly before
then additionally engaging a gear (manual gearbox) or moving the selector lever into position
P (automatic gearbox).
Rear parking aid*The parking aid provides a warning
of obstacles behind the vehicle.
The audible parking aid determines the di
stance between the rear bumper and an
obstacle located behind the ve
hicle with the aid of ultras
ound sensors. The tones of
the parking aid can be adapted in th
e menu of the information display*
⇒page 27.
The sensors are integrated in the rear bumper. Range of sensors The clearance warning begins at a distance
of about 160 cm from the obstacle (area
⇒ fig. 117
). The interval between the warning signals becomes shorter as the clear-
ance is reduced. A continuous tone sounds from
a distance of approx. 30
cm (area ) - danger area.
You should not reverse any further after this signal sounds!
If the vehicle is
equipped with a factory-fitted
towing device*, the border of the danger area starts,
continuous tone, 5 cm furt
her behind the vehicle. Th
e vehicle can be extended
through an installed deta
chable towing device.
On vehicles equipped with a factory-fitted
radio* or navigation system*, the distance
to the obstruction is shown graphically in the display. On vehicles with a factory-fitted towing device, the sensors are deactivated when towing a trailer. The driver is informed about this by a graphic display (vehicle towing
a trailer) in the radio* or the navigation*
display. The radio* or navigation system*, which is factory-fitted, can be set so that the play function volume decreases when acti

Technical Data
Automatic gearbox DSG*Automatic gearbox DSG*IntroductionYour car is equipped with an 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 transmission of the engine to the front wheels is not interrupted.Information for driving with the automatic gearbox DSG Shifting up and down through the gears is performed 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
⇒page 124.
Starting-off and Driving– Depress the brake pedal fully and keep it depressed. – Press the Shiftlock button (button in ha
ndle of the selector lever), move the
selector lever into the
desired position, e.g.
D ⇒page 122, and then release the
Shiftlock button.
– 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
⇒ page 110. At temperatures below -10 °C the engine can only be started in the selector lever position
P.
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 driv
e 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 mean
s of the “accelerator”, this means by
letting the clutch slip. This can lead to ov
erheating of the clutch
. If there is a risk
of overheating of the clutch due to overlo
ad, the clutch is op
ened automatically
and the vehicle rolls backward - risk of accident!•

offered must not tempt you to take greater risks than otherwise - risk of an acci- dent!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-free
operation of the ESP. Differing rolling circum
ferences of the tyres can lead to an unde-
sirable reduction in the engine output.•
Changes to vehicle (e.g. on engine, on th
e brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the ESP
⇒page 221, “Accesso-
ries, changes and replacement of parts”.Electronic Differential Lock (EDL)* The electronic differential lock prev
ents an individual wheel from slip-
ping.Models fitted with ESP ar
e 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 automaticall
y, 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 greate
r driving force to the other driven wheel.
This control process is also accompanied by noises. Overheating of the brakes The EDL switches off automatica
lly 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 driven 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.
EDL Off-road* After switching on the Off-road mode
⇒page 170, EDL Off-road is activated.
EDL Off-road is matched in such a way that it assists the traction of the vehicle when driving on an unfirm ground. EDL is activated earlier in the Off-road mode than in the normal mode. The brake pres- sure builts up more quickly on the slipping
wheel, on one axle, as well as diagonally.
WARNING
•
Carefully depress the accelerator when
accelerating on uniformly slippery
road surfaces, such as ice and snow. Th
e 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.
•
Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the EDL
⇒page 221, “Accesso-
ries, changes and replacement of parts”.
