Auto Check Control
Car state The Auto Check Control carries out a check of certain functions and vehicle com-
ponents. The check is performed constantly when the ignition is switched on,
both when the vehicle is stationary, as well as when driving.
Some operational faults, urgent repairs, service work or other information appear
in the display of the instrument cluster. The displays are shown with a red or yel-
low light symbol depending on the priority of the message.
The red symbols indicate danger (priority 1) while the yellow symbols indicate a
warning (priority 2). Information for the driver may also appear in addition to the
symbols ⇒ page 21.
There is at least one error message when the term Vehicle status is displayed in
the menu. After selecting this menu the first of the error messages is displayed.
Several error messages are shown on the display under the message e.g. 1/3. This
indicates that the first of a total of three error messages is displayed. Investigate
the displayed faults as soon as possible.
As long as the operational faults are not rectified, the symbols are always indica-
ted again. After the first display, the symbols are indicated without information for
the driver.
If a fault occurs, a warning signal will also sound in addition to the symbol and
text in the display:
● Priority 1 - three warning signals
● Priority 2 - one warning signal 
Red symbols A red symbol signals danger.
– Bring the vehicle to a stop.
– Switch the engine off.
– Investigate the function indicated.
– Obtain professional assistance.
Meaning of the red symbols:  Engine oil pressure too low ⇒ 
page 25  Overheated clutches of the automatic gear-
box DSG ⇒ page 29
Three successive warning signals will sound if a red symbol appears.

Yellow symbols A yellow symbol signals a warning.
Check the relevant function as soon as possible.
The meaning of the yellow symbols:  Check engine oil level,
engine oil sensor faulty
⇒ page 29
 Problem with en-
gine oil pressure It is also important to have the vehicle inspected
without delay by a specialist garage. The informa-
tion about the maximum permissible engine speed is displayed together with this symbol. In certain countries, if a yellow symbol appears
one warning signal will sound as
well.
If several operational faults of priority 2 exist, the symbols appear one after the
other and are each illuminated for about 5 seconds. 

Engine oil pressure 
The warning light
 comes on for a few seconds 1)
when the ignition is switched
on.
Stop the vehicle and switch the engine off if the warning light does not go off
after the engine has started or flashes while driving. Check the oil level and top up
with oil as necessary ⇒ page 183
, Replenishing engine oil.
An audible signal sounds three times as an additional warning signal.
Do not continue your journey if for some reason it is not possible under the con-
ditions prevailing to top up with oil. Keep the engine switched off and obtain pro-
fessional assistance from a specialist garage, otherwise it could lead to severe en-
gine damage.
Do not drive any further if the warning light flashes even if the oil is at the correct
level. Do not run the engine not at idling speed either. Contact the nearest spe-
cialist garage to obtain professional assistance.

- start engine
Applies to all models:
Position 1 To
lock the steering , with the ignition key withdrawn, turn the steering wheel un-
til 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 2 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
3 The engine is started in this position. At the same time switched on low beam or
main beam or other electrical components with major power consumption are
briefly switched off. The ignition key moves back into position
2 when one relea-
ses the key.
The ignition key must be turned back into position 1 each time before starting
the engine again. The starter repeat lock in the 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 selec-
tor lever is in position P.WARNING
● When driving, the ignition key must always be in the position 2 (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 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 start the engine or switch on electrical
equipment (e.g. power windows) - risk of accident or injury! Starting the engine
General You can only start the engine only using an original ignition key.
Manual gearbox
– Place the gearshift lever into neutral and put on the handbrake firmly before
starting the engine.
– Engage the clutch pedal and keep it depressed until the engine starts.
If you start the engine without depressing the clutch pedal, the engine does not
start and the following message appears in the Information display Depress
clutch! or CLUTCH in the display of the instrument cluster.
– Let go of the key as soon as the engine starts otherwise there may be damage
to the starter.
Automatic gearbox
– Place the gearshift lever into P or N before starting the engine, and apply the
handbrake firmly.
– 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 206. WARNING
● Never run the engine in non ventilated or enclosed areas. The exhaust
gases of the engine contain besides the odorless and colourless carbon mon-
oxide a poisonous gas - hazard! Carbon monoxide can cause unconsciousness
and death.
● Never leave your vehicle unattended with the engine running. £ 99
Starting-off and Driving Using the system Safety Driving Tips General Maintenance Breakdown assistance Technical data

–
For vehicles with petrol engine only refuel with unleaded petrol ⇒  page 176,
Unleaded petrol.
– Never run the fuel tank completely empty.
– Do not switch off the ignition while you are driving the vehicle.
– Do not pour too much oil into the engine ⇒
 page 183, Replenishing engine oil.
If you drive your vehicle in a country in which unleaded petrol is not available, you
must have the catalytic converter replaced later when driving the vehicle into a
country in which use of a catalytic converter is mandatory. WARNING
● In view of the high temperatures which may be produced in the catalytic
converter, one should always park a vehicle in such a way that the catalytic
converter cannot come into contact with easily flammable materials below the
vehicle - a risk of fire!
● Never use additional underbody protection or corrosion-protection agents
for the exhaust pipes, catalytic converters or heat shields. Such substances
might ignite when driving - risk of fire! CAUTION
● On vehicles fitted with a catalytic converter, never let the fuel tank run com-
pletely empty. An irregular fuel supply can result in poor ignition or misfiring. Un-
burnt fuel may get into the exhaust system and damage the catalytic converter.
● Filling the tank even only once with leaded petrol will result in the catalytic
converter being destroyed.
● If you detect misfiring, a drop in performance or irregular engine running when
driving, reduce your speed immediately and have the vehicle inspected by the
nearest specialist garage. The symptoms described may be caused by a fault in
the ignition system. Unburnt fuel may get into the exhaust system and damage
the catalytic converter. For the sake of the environment
Even if the exhaust system is operating properly, a sulphur-like exhaust odour
may be produced under certain operating conditions of the engine. This depends
on the sulphur content of the fuel. It is often sufficient to refuel with unleaded
premium-grade petrol of a different brand or at a different filling station. Driving in an economical and environmentally
conscious manner
General Your personal style of driving is a major factor.
Your fuel consumption, any pollution of the environmental and the wear-and-tear
to the engine, brakes and tyres, depend essentially on three factors:
● your personal style of driving,
● the conditions under which your vehicle is operated,
● technical aspects.
You can easily improve your fuel economy by 10 - 15 percent by driving in an eco-
nomical way with foresight. This section is intended to provide you with a number
of tips on how to protect the environment and at the same time save money.
The fuel consumption can naturally also be influenced by factors which are be-
yond the driver's control. It is, for example, normal for the fuel consumption to in-
crease in winter and under worsened conditions such as poor road conditions,
towing a trailer, etc.
The technical requirements for low fuel usage and economic efficiency of the ve-
hicle have already been built into the vehicle at the works. Special attention has
been given to minimising negative effects on the environment. It is necessary to
take note of the 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 foresight 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. 162

Regular servicing
A poorly tuned engine uses an unnecessarily high amount of fuel.
Having your vehicle serviced regularly at a specialist garage enables you to satisfy
one of the requirements for economical motoring even before you set off on your
journey. Keeping your vehicle properly serviced not only has a positive effect on
the safety of your vehicle and maintaining its value, but also saves on fuel.
A poorly tuned engine can result in a fuel consumption which is 10 % higher than
normal.
The foreseen maintenance work should be undertaken exactly according to the
Service schedule by a specialist garage.
Also check the oil level after refuelling. Oil consumption is dependent to a consid-
erable extent on the load and speed of the engine. Oil consumption could be as
high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine has a higher oil consumption at first, and rea-
ches its lowest level only after a certain running in time. It is therefore not possi-
ble to correctly assess the oil consumption of a new vehicle until after you have
driven about 5 000 km. For the sake of the environment
● You can achieve additional improvements in your fuel economy by using high-
lubricity oils.
● Check the ground below your car at regular intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garage if you find
any stains caused by oil or other fluids on the floor. Avoid driving short distances Short distances result in an above-average high fuel consumption.
Fig. 144 Fuel consumption in litres/100
km at different temperatures
– Avoid driving a distance of no more than 4 km if the engine is cold.
The engine and catalytic converter must first have reached their optimal operat-
ing temperature in order to effectively reduce fuel consumption and pollutant
emissions.
The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel immediate-
ly after starting. Fuel consumption drops to 10 litres/100 km after just 1 kilometre.
The engine reaches its operating temperature (outside temperature and engine
dependent) only after about 4 to 10 kilometres and the fuel consumption then
stabilizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature. The
⇒  fig. 144 shows the different fuel consumptions for the same distance, on the
one hand at +20 °C and on the other hand at -10
°C. Your vehicle has a higher fuel
consumption in winter than in summer. 
Checking tyre inflation pressures Tyres which are correctly inflated save fuel.
Always ensure that your tyres are inflated to the correct pressure at all times. The
rolling resistance will be increased if the tyre filling pressure is too low. This will
not only increase fuel consumption but also tyre wear and the driving behaviour
will worsen.
Always check the inflation pressure of the tyres when cold. £164
