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 35, “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 approximately 200 kilometres. New brake pads must be first “run in” before they develop their optimal fric
tion force. You can, however, compen-
sate for this slightly reduced braking fo rce by increasing the pressure on the
brake pedal. This guideline also applie s 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, please reduce your speed, shift down
into the next lower gear (manual gearbox) or select a lower driving stage (automatic
gearbox). This enables you to make full us e of the braking power of the vehicle and
reduces the strain on the brakes. Any additional braking should be done intermittently,
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)

Technical Data
Antilock brake system (ABS)ABS prevents the wheels locking when braking.General
The ABS contributes significantly to enhanc ing the active safety of your vehicle.
Compared to a vehicle not fitted with the ABS brake system, you are able to retain
optimal steering ability even during a full br ake application on a slippery road surface
because the wheels do not lock up.
In general you must not expect 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 noticeable
from a pulsating movement of the brake pedal which is accompanied by noises.
This is consciously intended to provide 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.
Visit a specialist garage as quickly as poss ible and adjust your style of driving to
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 34.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can in fluence the function of the ABS page 234, “Accesso-
ries, changes and replacement of 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 a pply 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 qu ick operation of the brake pedal. In such
cases, a much greater braking pressure exists than during a normal brake application.
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 dece leration of the vehicle. You must apply the brake pedal
firmly and hold it in this position in or der 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 switched 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 available. Further information on the ESP page 187.
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 the 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.

Uphill Start Assist*The uphill start assist makes it easier to start off on steep hills. The system assists a start
off by holding the brake pressure produced by the brake pedal actuation for approx. 2
seconds after releasing the brake pedal. The driver can therefore move his foot from
the brake pedal to the accelerator pedal and start off on the slope, without having to
actuate the handbrake. The brake pressure drops gradually the more you operate the
accelerator pedal. If the vehicle does not start off within 2 seconds, it starts to roll back.
The uphill start assist is active as of a 5 % slope, if the driver door is closed. It is always
active on slopes when in forward or reverse start off. When driving downhill, it is
inactive.Electromechanical power steeringThe power steering enables you to steer the vehicle with le ss 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 instru-
ment cluster page 31.
WARNING
Contact your specialist garage if the power steering is defective.
Tyre pressure monitoring system*The tyre pressure monitoring system compares with the aid of the ABS sensors the
speed and also the rolling circumference of the individual wheels. If the rolling circum-
ference of a wheel is changed, the warning light
 lights up in the instrument cluster
 page 34 and an audible signal sounds. The rolling circumference 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 heavily (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 the system
After changing the tyre inflation pressures, after changing one or several wheels, the
position of a wheel on the vehicle (e.g. ex changing the wheels between the axles) or
when the warning light lights up while drivin g, a basic setting of the system must be
carried out as follows.

Inflate all tyres to the specified inflation pressure page 228.

Switch on the ignition.

WARNING

When the warning light


The driver is responsible for the correct tyre inflation pressures. 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 pressure monitoring system does not take away the responsibility
from the driver for the correct tyre inflation pressure.Note
The tyre pressure monitoring 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 carefully 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 ba sic setting again every 10 000 km or 1x a
year.
Diesel particle filter* (diesel engine)In the diesel particle filter the resu lting soot particles are collected and
burnt during the combustion of diesel fuel.Code 7GG, 7MB or 7MG on the vehicle data sticker, see fig. 173 , indicates that your
vehicle is equipped with a diesel particle fi lter. The vehicle data sticker is located on
the floor of the luggage compartment and is also stated in the Service schedule.
The diesel particle filter filters the soot particles completely from the exhaust. The soot
is collected in the diesel particle filter and burnt regularly. To assist this procedure, we
recommend not to drive regu larly over short distances.
If the diesel particle filter is clogged or there is a fault, it is indicated by the warning light 
.
WARNING

The diesel particle filter achieves very high temp eratures. Therefore do not
park at points where the hot filter comes into direct contact with dry grass or
other combustible materials - risk of fire!

Never use additional underbody protection or corrosion-protection agents
for the exhaust pipes, catalytic converters, diesel particle filter or heat shields.

Driving and the EnvironmentThe first 1 500 kilometres and then afterwardsA new engine
The engine has to be run in during the first 1 500 kilometres.Up to 1 000 kilometres– Do not drive faster than 3/4 of the maximum speed of the gear in use, that is 3/4 of
the maximum permissi ble engine speed.
– Do not use full throttle.
– Avoid high engine revolutions.
– Do not tow a trailer.From 1 000 up to 1 500 kilometres– Increase the power output of the engine gradually up to the full speed of the gear
engaged, that is up to the maxi mum permissible engine revolutions.
During the first operating hours the engine ha s higher internal friction than later until
all of the moving parts have harmonized. Th e driving style which you adopt during the
first approx.1 500 kilometres plays a decisive part in the success of running in your
vehicle.
You should not drive at unnecessarily high engine revolutions even after the
running-in period is complete . The maximum permissible en gine speed is marked by
the beginning of the red zone on the scale of the revolutions counter. Shift up into the
next higher gear on a vehi cle fitted with manual gear box before the red zone is
reached. Extremely high engine revolutions are automatically governed, by the way.
For a vehicle fitted with a manual gearbox the converse situation also applies: Do not
drive at engine revolutions which are too low. Shift down as soon as the engine is no
longer running smoothly.
Caution
All the speed and engine revolution figures ap ply only when the engine is at its normal
operating temperature. Never rev up an engine which is cold, neither when the vehicle
is stationary nor when driving in individual gears.
For the sake of the environment
Not driving at unnecessari ly high engine revolutions and shifting to a higher gear as
early as possible are ways to minimise fu el consumption and operating noise levels
and protects the environment.New tyresNew tyres have to be “run in” since they do not offer optimal grip at first. You should
take account of this fact for the first 500 kilometres and drive particularly carefully.New brake padsAllow for the fact that new brake pads do no t achieve their full braking efficiency until
approximately 200 kilometres. New brake pads must be first “run in” before they
develop their optimal friction force. You ca n, 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.
During the running-in pe riod, you should avoid excessive stresses on the brakes. This
includes, for example, violent braking, part icularly from very high speeds, and also
when crossing mountain passes.

Catalytic converterProper operation of the emission cont rol system (catalytic converter) is
of major significance for driving your vehicle in an environmentally
conscious way.Please refer to the following guidelines.
– For vehicles with petrol engine only refuel with unleaded petrol  page 212.
– 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 218, “Replenishing engine oil”.
– Do not tow-start the vehicle over a distance of more than 50 metres page 242,
“Tow-starting and towing vehicle”.
If you drive your vehicle in a country in which unleaded petrol is not available, you
must have the catalytic converter replaced la ter when driving the vehicle into a country
in which use of a catalyti c 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

On vehicles fitted with a catalytic converte r, 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 system an d damage the catalytic converter.

Filling the tank even only once with le aded petrol will result in the catalytic
converter being destroyed.

If you detect a power reduct ion or irregular engine runni ng when driving, reduce
your speed immediately and have the vehicle inspected by the nearest specialist
garage. The symptoms described may be caus ed by a fault in the ignition system.
Unburnt fuel may get into the exhaust sy stem and damage the catalytic converter.For the sake of the environment
Even if the exhaust system is operating pr operly, a sulphur-like exhaust odour may be
produced under certain oper ating conditions of the engine. This depends on the
sulphur content of the fuel. It is often sufficient 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-
ical way with foresight. This section is intended to provide you with a number of tips 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 cond itions 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 maintain their effectiveness.
The optimal engine speed should be obtained 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 will 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.Shifting gears and saving energy
Shifting up early saves on fuel.Manual gearbox– Drive no more than about one length of your vehicle in first gear.
– Always shift up into the next higher gear at approx. 2 000 to 2 500 revs.Automatic gearbox– Depress the accelerator pedal slowly. Do not depress it beyond the kickdown
position, however. An effective way of achieving good fuel economy is to shift up
early. You will consume
more fuel if you drive at unnecessaril y high revolutions in any given gear.
The fig. 174 shows the ratio of fuel consumption to the speed of your vehicle in the
relevant gears. Fuel consumptio n in 1st gear is the highest, while that in 5th or 6th gear
is the lowest.
Only depress the accelerator pedal slowly if your vehicle is fitted with an automatic
gearbox in order to automatically select an economic driving programme. You will
achieve good fuel economy by shifting up early and shifting down late.
Note
Also use the information supplied by the multi-functional indicator* page 19.Avoiding full throttle
Driving more slowly means saving fuel.Sensitive use of the accelerator will not only significantly reduce fuel consumption but
also positively influence environmenta l pollution and wear of your vehicle.
You should avoid exploiting the top speed of your vehicle wherever possible. Fuel
consumption, pollutant emissions and vehicl e noises increase disproportionally at
high speeds.
The fig. 175 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 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 and pollutant emis sions, 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 refueling. 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 consumption 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 regular intervals to detect any leakages in
good time. Please have your vehicle inspec ted 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. 176 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.

Checking tyre inflation pressures
Tyres which are correctly inflated save fuel.Always ensure that your tyres are inflated to the correct pressure at all times. The rolling
resistance will be increased if the tyre filling pressure is too low. This will not only
increase fuel consumption but also tyre we ar and the driving behaviour will worsen.
Always check the inflation pr essure of the tyres when cold.
Do not drive with winter tyres all year round for this costs about 10 % more fuel.
Winter tyres are also louder.No unnecessary ballast
Transporting ballast costs fuel.The fact that every kilogram of extra weight increases your fuel consumption means
that it is worth taking a look in the luggage compartment to avoid transporting any
unnecessary ballast.
It is particularly in town traffic, when one is accelerating quite often, that the vehicle
weight will have a significant effect upon the fuel consumption. A rule of thumb here
is that an increase in weight of 100 kilograms will cause an increase in fuel consump-
tion of about 1 litre/100 kilometres.
You may frequently also leave a roof rack fitted on just out of convenience, although
you no longer need it. The increased aerodyna mic drag of your vehicle causes it to use
about 10% more fuel than normal at a speed of 100 - 120 km/h, even when you are not
carrying a load on the roof.Saving electricity
Generating electricity costs fuel.– Switch off electrical components as soon as you no longer need them.
When the engine is running, the alternator generates and supplies electrical power.
The greater the load on the alternator as a result of having a large number of electrical
components switched on, the more fuel will be consumed for operating the
alternator.
Keeping a log of your fuel consumptionIf you really wish to keep a close check on your fuel consumption, it is best to enter
the figures in a logbook. This does not take much time but is a very worthwhile exer-
cise. It enables you to detect any change (p ositive and negative) at an early stage and
to take any appropriate action.
If you find that your fuel consumption is too high, you should reflect on how, where
and in what conditions you have driven the vehicle since you last refuelled.Environmental compatibilityEnvironmental protection has played a major role in the design, selection of materials
