The warning light
flashes or comes on if the brake fluid level is too low, if there
is a fault in the ABS or if
the handbrake is applied.
If the warning light
flashes and an audible signal sounds three times (handbrake
is not applied),
stop
and check the brake fluid level

If there is a fault in the ABS which also in
fluences the function of the brake system
(e.g. distribution of brake pressure), the ABS warning light
comes on and at the
same time the brake system warning light starts flashing
. Be aware that not only
the ABS but also another part of th brake system is defective

.
An audible signal sounds three times as an additional warning signal.One should get used to high pedal forces, long braking distances and long free play of the brake pedal when driving to the next specialist garage. For further information on the brake system
⇒page 196, “Brakes”.
Handbrake applied The warning light
also comes on if the handbrake is applied. An audible warning
is also given if you drive the vehicle for at least 3 seconds at a speed of more than 6 km/h. The following text will be displayed in the information display*:
Release parking brake!
WARNING
•
Pay attention to the following instru
ctions before checking the brake
fluid level and opening the bonnet
⇒page 225, “Working in the engine
compartment”.•
If the brake system warning light
does not go out a few seconds after
switching on the ignition or comes on when driving, stop immediately and check the brake fluid in the reservoir
⇒page 231. If the fluid level has
dropped below the MIN marking, do not
drive any further - risk of accident!
Obtain professional assistance.Alternator
The warning light
comes on after the ignition has been switched on. It should go
out after the engine has started. If the warning light does not go out after
the engine has started, or comes on when
driving, drive to the nearest specialist garage. The vehicle battery will be discharged in this case so switch off all non-essential electrical components.
Caution
If the warning light
comes on when driving and in
addition the warning light
(cooling system fault) also comes on in display, you must then stop the car imme- diately and switch the engine off - risk of engine damage!Engine oil level
Warning light
lights up
If the warning light
lights up, the quantity of oil in the engine is probably too low.
Check as soon as possible the oil level or top up
⇒page 228, “Replenishing engine
oil” with engine oil. A peep sounds as an additional warning signal.The following text will be displayed in the information display*:
Check oil level!
The warning light will go out if the bonnet is
left open for more than 30 seconds. If
no engine oil has been replenished, the
warning light will come on again after
driving about 100 km.

Starting-off and Driving
124
Starting the engineGeneral 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 ma
y 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 i
mmediately 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 exhaus
t 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 vehi
cle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the pollutant emissions are lower.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 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 258.
•
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 temper-ature. The preglow indicator light

Seat belts
170
•
No two persons (also not children) should ever use a single seat belt
together.•
The maximum protection which seat belts can offer is only achieved if
you are correctly seated
⇒page 164, “Correct seated position”.
•
The belt webbing must no
t run across solid or fragile objects (e.g. spec-
tacles, ball-point pens, keys etc.) as this may be a cause of injuries.•
Bulky, loose clothing (e.g. a winter coat over a jacket) does not allow you
to be correctly seated and impairs proper operation of the seat belts.•
It is prohibited to use clamps or other objects to adjust seat belts (e.g. for
shortening the belts for smaller persons).•
The lock tongue should only be insert
ed into the lock which is the correct
one for your seat. Wrong use of the safety belt will reduce its capacity to protect and the risk of injury increases.•
The backrests of the front seats must not be tilted too far to the rear
otherwise the seatbelts can
lose their effectiveness.
•
The belt webbing must always be ke
pt clean. Soiled belt webbing may
impair proper operation of the inertia reel
⇒page 217, “Seat belts”.
•
The slot of the belt tongue must not be blocked by paper or similar
objects otherwise the belt tongue will not lock in place properly.•
Inspect the seat belts regu
larly to ensure they are
in good condition. If
you find seat belts which have damage to the seat belt webbing, seat belt connections, to the inertia reels or to the lock, the relevant safety belt must be replaced by a specialist garage.•
The seat belts must not be removed or changed in any way. Do not make
an attempt to repair the seat belts yourself.•
Damaged seat belts which have been subjected to stress in an accident
and were therefore stretched, must be replaced - this is best done by a specialist garage. The anchorage points
of the belts must also be inspected.
The anchorage points for the be
lts should also be checked.
•
In certain countries it is possible to use seat belts which differ in terms of
their operation from the seat belts wh
ich are described on the pages which
follow.

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 40, “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

Catalytic converterProper operation of the emission co
ntrol system (catal
ytic converter)
is of major significance for drivin
g your vehicle in an environmen-
tally conscious way.Please refer to the following guidelines: – For vehicles with petrol engine
only refuel with unleaded petrol
⇒
page 219, “Grades of 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 228, “Replenishing
engine oil”.
– Do not tow-start the vehicle over a
distance of more than 50 metres
⇒
page 253, “Tow-starting and towing vehicle”.
If you drive your vehi
cle 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 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, catalyti
c 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
completely empty. An irregular fuel supply can result in poor ignition or misfiring. Unburnt fuel may get into the exhaust sy
stem and damage the catalytic converter.
•
Filling the tank even only once with le
aded petrol will resu
lt 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 in
to 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 op
erating conditions of the en
gine. 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 economical way with foresight. This section is intended to provide you with a

Note
Also use the information supplied by the multi-functional indicator*
⇒page 21.
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. 201
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 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 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 vehicle at re
gular intervals to detect any leakages
in good time. Please have yo
ur vehicle inspected by a specialist garge if you find any
stains caused by oil or
other fluids on the floor.
