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 inju-
ries or major vehicle damage.
The engine compartment of your car is a hazardous area. There is a risk of
injuries, scalding, accidents and fire wh en working in the engine compartment,
e.g. inspecting and replenishing oil and other fluids. It is also essential to
observe all warnings page 140, “Working in the engine compartment”.Note
The arrangement of the indicator lights depends 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 symbol s (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.
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 di sconnected and reconnected, the yellow warning light
comes on after switching on the ignition. Th e warning light must go out after driving a
short distance.
Engine oil pressure
The warning light
comes on for a few seconds 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 142, “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 condi-
tions prevailing to top up with oil. Keep the engine switched off and obtain profes-
sional 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.
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 there-
fore check the oil level at regular interv als, preferably after every refuelling
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.
Glow plug system
(diesel engine)
The warning light
lights up for a cold engine when switching on the ignition (pre-
heat position) page 77. Start the engine after the indicator light goes out.
The glow plug indicator 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 syst em selects an emergency programme which enables you

soon as possible by applying and releasing the brakes several times.
There also may be a certain delay before the full braking efficiency is available when
driving on roads which have been treated with road salt if you have not used the brakes
for some considerable time beforehand. The layer of salt on the brake discs and brake
pads must first be rubbed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on th e bake pads occur if the vehicle has been
parked for a long period an d if you do not make much use of the braking system.
We recommend cleaning the brak e discs by firmly applying the brakes at a fairly high
speed if you do not make much use of the braking system or if surface corrosion is
present .
Faults in the brake surface
If you notice that the braking distance ha s suddenly become longer and that the brake
pedal can be depressed further, it is possible that a brake circuit of the dual-circuit
brake system has failed. Drive, in such cases, to the nearest specialist garage without
delay in order to have the problem rectified. Drive at a reduced speed while on your
way to the dealer and adapt your style of driving to the higher brake pedal pressure
required.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The level
of the brake fluid is monitored electronically page 28, “Brake system ”.
WARNING
Only apply the brakes for the purpose of drying and cleaning the brake discs
if the traffic conditions permit this. Do not place any other road users in jeop-
ardy.
When retrospectively mounting a front spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced other-
wise the braking system could run too hot.
Allow for the fact that new brake pads do not achieve their full braking effi-
ciency until after the first 200 kilometres . New brake pads must be first “run in”
before they develop their optimal friction force. You can, however, compensate for this slightly reduced braking force by increasing the pressure on the brake
pedal. This guideline also applies to any new brake pads installed at a future
date.
Caution
Never allow the brakes to rub by applying sl
ight pressure if you do not wish to brake
the vehicle. This causes the br akes to overheat and can also result in a longer braking
distance and excessive wear.
Before negotiating a steep downhill section, reduce your speed, shift down into the
next lower gear. This enables you to make full use of the braking power of the vehicle
and reduces the strain on the brakes. Any additional braking should be done intermit-
tently, not continuously.Note
The brake light flashes automatically in case of an emergency braking at speeds greater
than 60 km/h or with the intervention of th e ABS, which lasts longer than 1.5 seconds.
After the speed was reduced below 10 km/h or the vehicle was stopped, the brake light
stops flashing and the hazard warning light system switches on. The hazard warning
light system is switched of f automatically after accelerating or driving off again.Brake boosterThe brake booster boosts the pressure whic h you generate with the brake pedal. The
necessary pressure is only genera ted when the engine is running.
WARNING
Never switch off the engine befo re the vehicle is stationary.
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 cause an accident and severe injuries.WARNING (continued)

Reducing idling
Idling also costs fuel.It is worthwhile switching off the engine in a traffic jam or when waiting at a level
crossing or at traffic lights with a lengthy red phase. Even after just 30 - 40 seconds you
will have saved more fuel th an that is needed when you start the engine up again.
If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear an d pollutant emissions, though, are particularly high in
the warming-up phase. This is why you should drive off right after starting the engine.
Do avoid high engine revolu tions at this time, however.Regular servicing
A poorly tuned engine consumes an unnecessarily high amount of fuel.Having your vehicle serviced regularly at a specialist garge 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 on ly 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 fu el 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 consider-
able extent on the load and speed of the en gine. 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 reaches
its lowest level only after a certain running in time. It is therefore not possible to
correctly assess the oil consum ption 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 vehicle at regu lar intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garge 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.– Avoid driving a distance of no more than 4 km if the engine is cold.
The engine and catalytic converter mu st first have reached their optimal operating
temperature in order to effectively reduce fuel consumption and pollutant emissions.
The cold engine vehicle cons umes approx. 15 - 20 litres/100 km of fuel immediately
after starting. Fuel co nsumption drops to 10 litres/100 km after just 1 kilometre. The
engine reaches its operating temperat ure (outside temperature and engine
dependent) only after about 4 to 10 kilometres and the fuel consumption then stabi-
lizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature. The
fig. 116 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.

It is normal for the engine to consume oil. The oil consumption may be as much as 0.5
l/1 000 km depending on your style of driving and the conditions under which you
operate your vehicle. The oil consumption may be slightly hi gher than this during the
first 5000 kilometres.
One should therefore check the oil level at regular intervals, preferably every time after
the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range - but not above this, if
the engine has been operating at high load s, for example during a lengthy motorway
trip during the summer months, towing a tr ailer or negotiating a high mountain pass.
The warning light in the instrument cluster* will indicate page 25, “Engine oil pres-
sure ” whether the oil level is too low. In this case, check the oil level as soon as
possible. Top up with an appropriate quantity of oil.
Caution
The oil level must on no account extend beyond the range . Danger of damaging
the catalytic converter.
Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with oil. Switch the engine off and obtain professional
assistance from a specialist garage, otherwise it could lead to severe engine damage.Note
Engine oil specifications page 179, “Technical Data”.Replenishing engine oil– Inspecting the engine oil level page 141.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres page 180, “Engine oil spec-
ifications”.
– Inspect the oil level page 141.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
WARNING
Avoid dripping oil onto hot parts of the engine when topping up will oil - a
risk of fire!
Read and observe the warning notes page 140, “Working in the engine
compartment” before working in the engine compartment.For the sake of the environment
The oil level must on no acco unt extend beyond the range page 141. Oil will
otherwise be drawn in through the crankc ase ventilation and may pass through the
exhaust system to atmosphere. The oil ma y combust in the catalytic converter and
damage it.Changing engine oilThe engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator page 17, “Service Interval Display”.
WARNING
Only carry out the engine oil change, if you have the required professional
knowledge!
Read and observe the warning notes page 140, “Working in the engine
compartment” before working in the engine compartment.
First of all, let the engine cool down, we ar an eye protection and gloves - risk
of caustic burns due to hot oil.Caution
You must not pour any additives into the engine oil - risk of engine damage! Damage,
which results from such product, are excluded from the warranty.
For the sake of the environment
You must on no account pour oil into the ground or into the sewage system.
