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To lock the steering , with the ignition key withdrawn, turn the steering wheel until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 positi on, in order to release the steering lock.
Position
The engine is started in this position. At the same time any switched on low beam
or main beam or other electrical compon ents with major electrical consumers are
briefly switched off. The ignition key moves back into position after being
released.
The ignition key must be turned back into position 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.
WARNING
•
When driving, the ignition key must al ways 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 wheel - risk of accident!
•
Do not withdraw the ignition key from the lock until the vehicle has come to
a stop. The steering lock can engage 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 import ant if children are left in the vehicle.
Children might otherwise start 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 an d put on the handbrake firmly before
starting the engine.
•
Before starting, it is necessary to depress the clutch pedal and to keep it pressed
down until the engine starts. If you try and start the engine without pressing the
clutch pedal, the engine will not start. A message in the information display of the
instrument cluster will also appear indicate the need to press the clutch pedal.
•
Let go of the ignition key as soon as the engine starts otherwise you may
damage 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 clear-
ance compensation. This is quite norm al 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 153.
It is only possible to tow-start vehicles fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres. Observe the following
guidelines page 154, “Tow-starting and towing vehicle”.
WARNING
•
Never run the engine in non ventilated or enclosed areas. The exhaust gases
of the engine contain besides the odourless 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 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 operating temperature - risk of damaging the
engine!
•
Vehicles which are fitted with an exhaus t 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 emissions are lower.

Technical Data
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 star ting after 10 seconds if the engine does not start
right away and wait for about 30 seconds before repe ating 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 156.
•
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 elec trical 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 away and wait for about 30 seconds before repe ating 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 156.
•
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 tur ning the ignition key into position
page 73, fig. 84 .
WARNING
•
Never switch off the engine before the ve hicle is stationary - risk of accident!
•
The brake booster only operates when the engine is running. Greater phys-
ical effort for braking is required when en gine is switched off. Because if you do
not stop as normal, this can caus e 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 period 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 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
a c c um ul a tio n o f he a t i n the en g in e o r i f the engine is warm and the engine compart-
ment is additionally heat ed by strong sunlight.
•
This is why particular care is required when carrying out any work in the engine
compartment page 131, “Working in the engine compartment”.

instrument cluster page 26 and an audibl e signal sounds. The rolling circumfer-
ence of the tyre can change if:•
the tyre inflation pressure is too low,
•
the structure of the tyre is damaged,
•
the vehicle is loaded on one side,
•
the wheels of an axle are loaded heavil y (e.g. when towing a trailer or when
driving uphill or downhill),
•
snow chains are mounted,
•
the temporary spare wheel is mounted,
•
one wheel per axle was changed.
Basic setting of tyre inflation pressure-control system
After changing the tyre inflation pressures, after changing one or several wheels,
the position of a wheel on the vehicle (e.g. exchanging the wheels between the
axles) or when the warning light lights up while driving, a basic setting of the
system must be carried out as follows.
•
Inflate all tyres to the specified inflation pressure page 141.
•
Switch on the ignition.
•
Press button page 109, fig. 113 for more than 2 seconds. While pressing
the button, the warning light
lights up. At the same time the memory of the
system is erased and the new calibration is started, which is confirmed with an
audible signal and then the warning light
goes out.
•
If the warning light
does not go out after the basic setting, there is a fault in
the system. Have the vehicle inspected by your nearest specialist garage.
Warning light
lights up
If the tyre inflation pressure of at least one wheel is insufficiently inflated in
comparison to the stored basic value, the warning light
lights up.
Warning light
flashes
If the warning light flashes, there is a system fault. Have the vehicle inspected by
your nearest specialist garage.
WARNING
•
When the warning light
lights up, immediately reduce the speed and
avoid sudden steering and brake manoeu vres. Please stop the vehicle without
delay at the nearest possible stop and inspect the tyres and their inflation pres-
sures.
•
The driver is responsible for the correct tyre inflation pressure. For this
reason, the tyre inflation pressu res must be checked regularly.
•
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light
can be delayed or does not light up at all.
•
The tyre inflation pressure-control syst em does not take away the responsa-
bility from the driver for the correct tyre inflation pressure.Note
The tyre inflation pres sure-control system:•
does not replace the regular tyre inflatio n pressure control, because the system
cannot detect an even pressure loss,
•
cannot warn in case of very rapid tyre inflation pressure loss, e.g. in case of
sudden tyre damage. In this case carefull y bring the vehicle to a standstill without
sudden steering movements and without sharp braking.
•
In order to ensure a proper functioning of the tyre inflation pressure-control
system, it is necessary to carry out the basic setting again every 10 000 km or 1x a
year.

– Do not tow-start the vehicle over a distance of more than 50 metres
page 154, “Tow-starting and towing vehicle”.
If you drive your vehicle in a country in wh ich 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 cata lytic 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
•
Vehicles fitted with cataly tic converter should never be allowed to let the fuel
tank to run completely empty. An irregular fuel supply can result in poor ignition or
misfiring. Unburnt 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 su fficient to refuel with unleaded premium-
grade petrol of a different brand or at a different filling station.
Driving in an economical and environmentally
conscious mannerGeneral
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 econom-
i c a l w a y w i t h f o r e s i g h t . T h i s s e c t i o n i s i n t e n d e d t o p r o v i d e y o u w i t h a n u m b e r o f t i p s
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 beyond
the driver's control. It is, for example, normal for the fuel consumption to increase
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
vehicle 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 main tain their effectiveness.
The optimal engine speed should be obtain ed 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 forsight you will not
need to brake so often and wi ll 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.
