Instruments and Indicator/Warning Lights
24WARNING
Have the airbag system checked immediat ely by a specialist garage if a fault
exists. Otherwise, there is a risk of the airbag not being activated in the event
of an accident.Control system for exhaust

The warning light
 comes on after the ignition has been switched on.
If the warning light does not go out after st arting the engine or it lights up when
driving, a fault exists in an exhaust relevant component. 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.
Electromechanical power steering
 
The warning light
 comes on for a few seconds when the ignition is switched on.
If the warning light after switching on the ignition or when driving lights up contin-
uously, a fault exists in the electromechanical power steering.
•
If the yellow warning light lights up
, this indicates a partial failure of the
power steering and the steering forces can be greater.
•
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 109.
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

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 driv ing. Check the oil level and top up with
oil as necessary page 132, “Replenishing engine oil”.
An audible signal sounds three time s 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 prof essional assistance.
WARNING
•
If you must stop for technical reasons, then park the vehicle at a safe
distance from the traffic and switch of f 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.

come to a stop. The steering lock might otherwise engage unintentionally - risk
of accident!Caution
•
Each key contains electronic components; therefore protect them against mois-
ture and severe shocks.
•
Keep the groove of the keys absolutely clean as impurities (textile fibres, dust
etc.) have a negative effect on the proper operation of the locking cylinder and the
ignition lock.

Starting-off and Driving
74
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!

•
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.

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 27, “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 an y new brake pads installed at a future
date.Caution
•
Never allow the brakes to rub by applying slight 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 section, reduce your speed, shift down into
the next lower gear. This enables you to ma ke full use of the braking power of the
vehicle and reduces the strain on the brakes. Any additional braking should be done
intermittently, no t continuously.Note
The brake light flashes automatically in ca se of an emergency braking at speeds
greater than 60 km/h or with the interven tion of the 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 off automatically after accelerating or
driving off again.Brake boosterThe brake booster boosts the pressure wh ich you generate with the brake pedal.
The necessary pressure is only generated when the engine is running.
WARNING
•
Never switch off the engine be fore 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 caus e an accident and severe injuries.
Antilock brake system (ABS)ABS prevents the wheels locking when braking.General
The ABS contributes significantly to enhancing the active safety of your vehicle.
Compared to a vehicle not fitted with ABS, you are able to retain optimal steering
ability even during a full brake application on a slippe ry road surface because the
wheels do not lock up.
You must not expect, however, that the braking distance will be shorter under all
circumstances as a result of the ABS. The braking distance for example on gravel
and fresh snow, when you should anyway be driving slowly and cautiously, will be
longer.
Operating principle
The brake pressure will be reduced on a wheel which is rotating at a speed which is
too low for the speed of the vehicle and tending to lock. This control cycle is notice-
able from a pulsating movement of the brake pedal which is accompanied by
noises. This is consciously intended to pr ovide the driver with the information that
the wheels are tending to lock (ABS control range). You must always keep the brake
pedal depressed to enable the ABS to optimally control the brake application in this
braking range. Never interrupt the application of the brakes!
WARNING
•
The ABS can also not overcome the physical limits of your vehicle. Please do
not forget this, particularly when driving on icy or wet road surfaces. If the ABS
is operating within the control range, adapt your speed immediately to the
conditions of the road surface and the traffic situation. The increased safety
offered by the ABS must not tempt you to take greater risks than otherwise -
risk of an accident!
•
The normal braking system is still fully functional if there is an ABS fault.

Technical Data
take account of the ABS fault in the meantime since you will not know the
extent of the fault and in how far
the braking efficiency is affected.
Note
•
A warning light comes on if a fault occurs in the ABS system
  page 26.
•
Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the ABS page 146,
“Accessories, changing and replacing parts”.
Brake Assist*During a severe brake application (e.g. if a hazard exists), the Brake Assist increases
the braking force and thus makes it possible to rapidly produce the pressure
required in the brake system.
The majority of drivers do apply the brakes in good time in dangerous situations, but
do not depress the brake pedal with sufficient pressure. Consequently, it is not
possible for the vehicle to achieve its maximum deceleration and the vehicle covers
a greater distance than necessary.
The Brake Assist is activated by the very quick operation of the brake pedal. In such
cases, a much greater braking pressure exists than during a normal brake applica-
tion. This makes it possible, even with a relatively low resistance of the brake pedal,
to produce an adequate pressure in the brake system in the shortest possible time,
which is required for maximum deceleration of the car. You must apply the brake
pedal firmly and hold it in this position in order to achieve the shortest possible
braking distance.
The Brake Assist is able to help you achi eve a shorter braking distance in emergency
situations by rapidly producing the pressure required in the brake system. It fully
exploits the attributes of the ABS. After you release the brake pedal, the function
of the Brake Assist is automatically swit ched off and the brakes operate in the
normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake
Assist function is also not availa ble. Further information on the ESP page 105.
WARNING
•
The Brake Assist is also not able to overcome the physical limits of your
vehicle in terms of the braking distance required.
•
Adapt your speed to the conditions of th e road surface and to the traffic situ-
ation.
•
The increased safety offered by the Brake Assist must not tempt you to take
a greater safety risk than otherwise.
Electromechanical power steeringThe power steering enables you to steer the vehicle with less physical force.
With the electromechanical power steering, the steering assist is automatically
adapted to the speed and to the steering angle.
It is still possible to fully steer the vehicle if the power steering fails or if the engine
is not running (vehicle being towed in). The only difference is that greater physical
effort is required.
If there is a fault in the power steering, the warning light
 or  lights up in the
instrument cluster page 24.
WARNING
Contact your specialist garage if the power steering is defective.Tyre inflation pressure-control system*The tyre inflation pressure-control system compares with the aid of the ABS
sensors the speed and also the rolling circumference of the individual wheels. If the
rolling circumference of a wheel is changed, the warning light
