Ignition lock
Petrol engines
- ignition switched off, engine off, the steering can be locked.
- ignition switched on
- start engine
Diesel engines - interruption of fuel supply, ignition switched off, engine off, the steering can
be locked.
- heating glow plugs on, ignition switched on
•You should not switch on any major elec trical components during the heating
period otherwise the vehicle batter y will be drained unnecessarily.
- start engine
Applies to all models:
Position
To lock the steering , with the ignition key withdrawn, turn the steering wheel until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 switched on low beam or
main beam or other electrical compon ents with major power 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 ru nning 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 (put on the handbrake or select the selector lever posi-
tion P). The steering lock can enga ge 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 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!

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 th e 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 257.
•Contact the nearest specialist garage to obtain professional assistance.
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- tion into ⇒page 125, fig. 146 .
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 your 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 continue running fo r 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 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.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Rear parking aid*
The parking aid provides a warning of obstacles behind the vehicle.
The audible parking aid determines the distance between the rear bumper and an
obstacle located behind the vehicle with the aid of ultrasound sensors. The tones
of the parking aid can be adapted in the menu of the information display*
⇒ page 30. 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. 149 ). The interval between the warning signals becomes shorter as the
clearance is reduced.
A continuous tone sounds from a clearanc e of just 30 cm (Bereich ) - danger
area. You should not reverse any further after this signal sounds! If the vehicle
is equipped with a factory-fi tted towing device*, the border of the danger area
starts - continuous tone - 5 cm further behind the vehicle. The vehicle can be
extended through an installe d detachable towing device.
On vehicles equipped with a factory-fitted radio* or navigation*, the distance to the
obstruction is shown graphically on the disp lay. On vehicles with a factory-fitted
towing device, the sensors are deactivated when towing a trailer. The driver is also
informed of the radio* or the navigation* by a graphic display (vehicle towing a
trailer) on the display. The radio* or navi gation*, which is factory-fitted, can be set
so that the play function volume decrea ses when activating the parking aid, see Owner's Manual radio* or navigation*. This improves the audibility of the parking
aid.
Activating
The parking aid is activated automatically when
reverse gear is engaged and the
ignition is turned on. This is conf irmed by a brief acknowledgement signal.
Deactivating
The parking aid is deactivated by removing the reverse gear.
WARNING
•The parking aid is not a substitute for the driver paying proper attention
and it is always the driver's responsibility to take care when parking the
vehicle or carrying ou t similar manoeuvres.
•You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin po st, trailer drawbar etc., behind your
vehicle. Such an obstacle might not be within the range detected by the
sensors.
•Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the parking aid. Thus, these objects or
people who wear such clothing are not recognised by the sensors of the
parking aid.
Note
•The parking aid does not operate if you are towing a trailer (applies to models
which feature a factory-fi tted towing device*).
•If a warning signal sounds for about 3 seconds after switching the ignition on
and engaging reverse gear, and there is no obstacle close to your car, this indicates
a system fault. 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.

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 car, th is indicates a system fault. The fault is
confirmed additionally when the symbol flashes in the button ⇒page 130,
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

move).
Cruise control system (CCS)*
Introduction
The 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 which 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 gearbox to switch on the
cruise control system if the sele ctor lever is in the position P, N or R.
Storing a speed
The 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 ⇒fig. 152 into the position ON.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical 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 ⇒page 138.
Starting-off and Driving
– Depress the brake pedal fully and keep it depressed.
– Press the Shiftlock button (button in handle of the selector lever),
move the selector lever into the desired position, e.g. in D, 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 stop-
ping just for a short time, such as at a cross roads. It is absolutely suffi-
cient to hold the stopped vehicle stationary by depressing 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 126. 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 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 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 clutch 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 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 clut ches, finally the clutches are opened. The
power transmission from the engine to the front wheels is interrupted and as a

The gearbox does not shift into the 6th gear in the position
S, because the
maximum speed is reached with the 5th gear
12).
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 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 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 peda l 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:
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 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 acceleration
power.
Depressing the accelerator 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 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!
12)Not valid for vehicles with automatic gearbox DSG.

Shifting up gears
– One-touch forward of the selector lever (in the Tiptronic position)
⇒page 138, fig. 155 .
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 ge arbox does not shift down until there is
no risk of the engine overrevving.
If you operate the kickdown function, the ge arbox shifts into a lower gear in line
with the vehicle speed and engine speed.
Manual shifting on the multifunction steering wheel*
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
– Press the right rocker switch
⇒fig. 157 for the multifunction
steering wheel.
Shifting down gears
– Press the left rocker switch ⇒fig. 157 for the multifunction
steering wheel.
Temporarily switching over to manual shifting
– If the selector lever is in position D or S, press the left rocker switch
or the right rocker switch fo r the multifunction steering wheel.
– If the rocker switches or are not pressed for some time, the manual shifting switches off. You can also switch off the temporary
switch over to manual shifting by pressing the right rocker switch
for more than 1 second.
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 switched over to emergency mode, drive to the nearest
specialist garage in order to have the fault rectified.
