WARNING
•If you do not pay attention to the warning lights coming on and the corre-
sponding descriptions and warning notes, this may result in severe body
injuries or major vehicle damage.
•The engine compartment of your car is a hazardous area. There is a risk
of injuries, scalding, accidents and fire when working in the engine
compartment, e.g. inspecting and replenis hing oil and other fluids. It is also
essential to observe all warnings ⇒page 225, “Working in the engine
compartment”.
Note
•The arrangement of the indicator light is dependent on the model version. The
symbols shown in the following functional description are to be found as indicator
lights in the instrument cluster.
•Operational faults are shown in the instrument cluster as red symbols (priority
1 - danger) or yellow symbols (priority 2 - warning).
Turn signal system
Either the left or right indicator light flashes depending on the position of the
turn signal lever.
The indicator light flashes at twice its normal rate if a turn signal light fails. This does
not apply when towing a trailer.
Switching off the hazard warning light system is switched on will cause all of the
turn signal lights as well as both indicator lights to flash.

WARNING
Contact your specialist garage if the power steering is defective.
Note
•If the yellow warning light goes out after starting the engine again and a short
drive, it is not necessary to visit a specialist garage.
•If the battery has been disconnected an d reconnected, the yellow warning light comes on after switching on the ignition. The warning light must go out after
driving a short distance.
Engine oil pressure
The warning light comes on for a few seconds 4) when the ignition is switched
on.
Stop the vehicle and sw itch 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 228, “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
conditions prevailing to top up with oil. Keep the engine switched off and obtain
professional assistance from a specialist garage, otherwise it could lead to severe
engine 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 specialist
garage to obtain professional assistance.
The following text will be displayed in the information display*:
Oil Pressure Engine off! Owner's manual
WARNING
•If you must stop for technical reasons, then park the vehicle at a safe
distance from the traffic and switch off the engine and switch on the hazard
warning light system.
•The red oil pressure light is not an oil level indicator! One should
therefore check the oil level at regular intervals, preferably after every refu-
eling stop.
EPC fault light (petrol engine)
The (Electronic Power Control) warning light comes on for a few seconds when
the ignition is switched on.
If the warning light
does not go out or lights up after starting the engine, a fault
exists in the engine control. The engine management system selects an emergency
programme which enables you to drive to the nearest specialist garage by adopting
a gentle style of driving.
The following text will be displayed in the information display*:
Engine fault Workshop! (Engine fault workshop!)
Glow plug system (diesel engine)
The warning light lights up for a cold engine when switching on the ignition
(pre-heat position) 2 ⇒ page 125. Start the engine after the indicator light goes out.
The glow plug indicato r light will come on for about 1 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.
There is a fault in the glow plug system if the warning light
does not come on
at all or lights up continuously . Contact a specialist garage as soon as possible to
obtain assistance.
If the warning light
begins to flash while driving, a fault exists in the engine
control. The engine management system selects an emergency programme which 4)The warning light on vehicles fitted with information display does not come on after
switching the ignition on, but only if a fault exists or the engine oil level is too low.

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!

Starting the engine
General
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 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 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 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 oper ating temperature - risk of damaging the
engine!
•Vehicles which are fitted with an exhaust 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 vehicle is standing. Drive off right away.
Through this 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 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 257.
•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 temper-
ature.
The preglow indicator light
comes on after the igniti on 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 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.
