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 majo
r 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 obse
rve all warnings
⇒page 223, “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 inst
rument 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.

Technical Data
•
If the
red
warning light lights up
, this indicates a complete failure of the
power steering and the steering assist has failed (significantly higher steering forces). Further information
⇒page 198.
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
and 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

comes on for a few seconds
3) 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 225.
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*:

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)

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
.
3)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.

WARNING
Even with this function the vehicle ca
nnot steer itself! The
driver is further-
more responsible for the steering of the vehicle!BrakesWhat has a negative effect on braking efficiency?Wear-and-tear Wear-and-tear to the brake pads is greatly dependent on the operating conditions of the vehicle and your style of driving. Particularly if you drive a great deal in towns and over short distances or if you adopt a
sporty style of driving, it may be neces-
sary to have the thickness of the brake
pads inspected at a specialist garage
between the service inspections. Wet roads or road salt There may be a certain delay before the br
akes take full effect under certain condi-
tions such as when driving through water,
during heavy rain
showers or after the
vehicle has been washed in
an automatic vehicle wash, since the brake discs and
brake pads may be moist or even have a
coating of ice on them in winter. You
should dry the brakes as soon as possib
le 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 wi
th road salt if yo
u have not used the
brakes for some considerable time beforeha
nd. The layer of salt on the brake discs
and brake pads must first be rubb
ed 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 and if you do
not make much use of the braking system.
We recommend cleaning the brake 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 corro- sion is present
⇒
.
Faults in the brake surface If you notice that the braking distance
has 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 41, “Brake system
”.
WARNING
•
Only apply the brakes for the purpos
e of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users in jeopardy.•
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 otherwise the braking sy
stem could run too hot.
•
Allow for the fact that new brake pads
do not achieve th
eir full braking
efficiency until approximately 200 kilo
metres. 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 pres-
sure on the brake pedal. This guidelin
e also applies to any new brake pads
installed at a future date.
Caution
•
Never allow the brakes to ru
b by applying slig
ht pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.•
Before negotiating a steep downhill sect
ion, please reduce your speed, shift
down into the next lower gear (manual ge
arbox) or select a lower driving stage
(automatic gearbox). This enables you to make full use of the braking power of the

Driving and the Environment
204
Avoiding full throttle Driving more slowly means saving fuel.Sensitive use of the accelera
tor will not only significantly reduce fuel consumption
but also positively influence environmen
tal pollution and wear of your vehicle.
You should avoid fully exploi
ting the top speed of your vehicle wherever possible.
Fuel consumption, pollutant emissions and vehicle noises increase disproportion- ally at high speeds. The
⇒fig. 195
shows the ratio of fuel consumption to the speed of your vehicle.
You will cut your fuel consumption by half
if you only make use three-quarters of
the possible top speed of your vehicle.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 length
y red phase. Even after just 30 - 40 seconds
you will have saved more fuel than 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 and pollutant em
issions, 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 re
volutions 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 moto
ring even before you set off on your
journey. Keeping your vehicle properly servic
ed 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 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 refueling.
Oil consumption
is dependent to a consid-
erable extent on the load and speed of
the engine. Oil consum
ption 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 ha
s 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 cons
umption 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 regula
r 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.
