Layout of this Owner's Manual (explanations)
6Layout of this Owner's Manual (explanations)The Owner's Manual has been systematically designed, in order to make it easy for you to find and absorb the information you require.Chapters, table of contents and subject indexThe text of the Owner's manual is divided into relatively short sections which are combined into easy-to-read
chapters
. The chapter you are reading at any particular
moment is highlighted at the bottom right of the page. The
Table of contents
is arranged according to the chapters and the detailed
Subject
index
at the end of the Owner's Manual helps
you to rapidly find the information you
are looking for.SectionsThe majority of
Sections
apply to all models.
Since there is a wide range of different equipment and options available it is clearly unavoidable, despite dividing the contents
into sections, that
mention may be made
of equipment whic
h is not fitted to your vehicle.
Brief information and instructionsEach section has a
Heading
.
This is followed by
Brief information
(in large italic lettering), which tells you the
subject which is dealt with in this section. Most of the illustrations are accompanied by an
Instruction
(in relatively large letters)
which explains to you in a straightforw
ard way the action you have to take.
Work steps
which have to be carried out are illustrated with a hyphen.Direction indicationsAll direction indications such as “left”, “right”,
“front”, “rear” relate to the direction of
travel of the vehicle.Explanation of symbols Equipment which is marked in such a way is only standard on certain vehicle model versions or only suppliable as opti
onal equipment for certain models.
End of a section.
The section is continued on the next page.NotesAll four kinds of notes, which are used in th
e text, are always stated at the end of the
respective section.
WARNING
The most important notes are marked
with the heading WARNING. These
WARNING notes draw your attention to a serious risk of accident or injury. While reading the text you will frequent
ly encounter a double arrow followed
by a small warning symbol. This symbol is intended to draw your attention to a WARNING note at the end of the section to which you must pay careful atten- tion.
Caution
A Caution
note draws your attention to the possib
ility of damage to your vehicle (e.g.
damage to gearbox), or points ou
t general risks of an accident.
For the sake of the environment
An
Environmental
note draws your attention to environmental protection aspects.
This is where you will, for example, find tips
aimed at reducing your fuel consumption.
Note
A normal
Note
draws your attention in a general way to important information.

e selector lever position D of the automatic
gearbox before reaching the red zone of the rev counter scale. Avoid high engine speeds du
ring the driving time and before the engine has been
warmed up to operating temperature
page 145.
For the sake of the environment
Shif ting to a highe r g ear in g ood tim e hel p
s to reduce the fuel
consumption, minimises
operating noise levels, protects the environment and contributes to a longer life and reliability of the engine.SpeedometerWarning against excessive speeds* An acoustic warning signal will sound when
the vehicle speed exceeds 120 kilometres
per hour. The acoustic warning signal will switch off again when the vehicle speed goes below this speed limit.
Note
This function is only
valid for some countries.
Coolant temperature gauge*The coolant temperature gauge
page 15, fig. 15
operates only when the ignition
is switched on. In order to avoid any damage to the engine,
please pay attention to the following notes
regarding the temperature ranges. Cold range If the pointer is in the left-hand area of the scale it means that the engine has not yet reached its operating temperatur
e. Avoid running at high engine speeds, at full throttle
and at severe engine loads.
The operating range The engine has reached its operating temperature as soon as the pointer moves into the mid-range of the scale. The pointer may
also move further to the right at high
engine loads and high outside temperatures. This is not critical provided the warning symbol
in the instrument cl
uster does not flash.
If the symbol
in the instrument cluster flashes it means that either the coolant
temperature
is too high or the coolant
level
is too low. Observe the guidelines
page 29, “Coolant temperature/coolant quantity
”.
WARNING
Pay attention to the warning notes
page 166, “Working in the engine
compartment” before opening the bonn
et and inspecting the coolant level.
Caution
Additional headlights and other attached components in front of the fresh air inlet impair the cooling effi
ciency of the coolant. There is
then a risk of the engine over-
heating at high outside temper
atures and high engine loads.
Fuel gauge*The fuel gauge
page 15, fig. 15
only operates when the ignition is switched on.
The fuel tank has a capacity of
about 45 litres. The warning symbol
in the instrument
cluster lights up when the pointer reaches the reserve marking. There are now about 7 litres of fuel remaining in the tank.
This symbol is a reminder for you,
that you must
refuel
.
The following will be displayed in the information display*:
Please refuel!
An audible signal sounds as an additional warning signal.On some vehicles, the fuel gauge is shown
in the display of the instrument cluster.

Technical Data
Traction control system (TCS)*
The warning light
lights up if the TCS
system is switched off.
Further information about the TCS
page 138.
Tyre pressure monitoring system*
The warning light
lights up, if there is a substantia
l drop in inflation pressure in one
of the tyres. Reduce the speed and check or
correct as soon as possible the inflation
pressure in the tyres
page 178.
An audible signal sounds as an additional warning signal.If the warning light flashes
, there is a system fault. Visit the nearest specialist garage
and have the fault rectified. Further information about the tyre pressure monitoring system
page 142.
WARNING
When the warning light
lights up, immediately reduce the speed and
avoid sudden steering and brake manoeuvr
es. Please stop the vehicle without
delay at the nearest possible stop and in
spect the tyres and their inflation pres-
sures.
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.
Note
If the battery has been disconnected, the warning light
comes on after switching on
the ignition. The warning light must go out after driving a short distance.Selector lever lock*
(automatic gearbox)
If the
green
warning light
lights up, operate the brake pedal. This is necessary, in
order to be able to move the selector lever out of the position
P or N.
Further information about the selector lever lock
page 100.
Traction control system (TCS)*
The warning light
comes on for a few seconds when the ignition is switched on.
The warning light flashes when a control cycle is activated while driving.The warning light
lights up permanently if there is a fault in the TCS system.
The fact that the TCS system operates together with the ABS means that the TCS warning light will also come on if the ABS system is not operating properly. If the warning light
comes on immediately after starting the engine, the TCS system
can be switched off for techni
cal reasons. In this case, the TCS system can be switched
on again by switching the igni
tion on and off. If the warning light goes out, the TCS
system is fully functional again. Further information about the TCS
page 138, “Traction control system (TCS)*”.
Note
If the battery has been disconnected
and reconnected, the warning light
comes on
after switching on the ignition. The warning light must go out after driving a short distance.Electronic stability programme (ESP)*
The warning light
comes on for a few seconds when the ignition is switched on.
If the ESP helps to stabilise the vehicle (f
or example when applying and releasing a
braking force to an individual wheel), then the indicator light
flashes.
The warning light
lights up permanently if there is a fault in the ESP system.
The fact that the ESP system operates together with the ABS means that the ESP warning light will also come on if the ABS system is not operating properly. If the warning light
comes on immediately after starting the engine, the ESP system
can be switched off for technical reasons. In
this case, the ESP system can be switched
on again by switching the igni
tion on and off. If the warning light goes out, the ESP
system is fully functional again. Further information on the ESP
page 137, “Electronic stab
ility programme (ESP)*”.

WARNING
Pay attention to the following instruct
ions before checking the brake fluid
level and opening the bonnet
page 166, “Working in the engine compart-
ment”.
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 171, “Brake fluid”. If the fluid level
has dropped below the MIN marking, do no
t drive any further - risk of accident!
Obtain professional assistance.Cruise control system*
The warning light
lights up, when operating the speed regulating system.
Airbag system
Monitoring the airbag system The warning light
comes on for a few seconds when the ignition is switched on.
There is a fault in the system if the warning
light does not go out or comes on or flashes
while driving
. This also applies if the warning
light does not come on after the
ignition is switched on. The following text will be displayed in the information display*:
Airbag fault!
The functionality of the airbag system is also monitored electronically when one airbag has been switched off. The following situation applies if the fr
ont, side and head airbags or belt
tensioner have been switched off
using the vehicle system tester:
The warning light
lights up for 3 seconds after switching on the ignition and then
flashes for 12 seconds afterwards in 2 second intervals. The following text will be displayed in the information display*:
Airbag/belt tensioner deactivated!
If the passenger front airbag has been
switched off using the switch (for
switching off airbags)* in the end face of
the dash panel on the front passenger
side:
The warning light
comes on for 4 seconds after the ignition has been switched
on.
switching off the airbag is indicated in the middle of the dash panel by the lighting
up of the yellow indicator light in display
page 129.
WARNING
Have the airbag system checked immediat
ely by a specialist
garage if a fault
exists. Otherwise, there is a
risk of the airbag not bein
g activated in the event of
an accident.
Note
Further information about switching off airbags
page 128, “Deactivating airbags”.
Diesel particle filter*
(diesel engine)
If the warning light
comes on, this means that soot
has accumulated in the diesel
particle filter because of the frequent short distances. In order to clean the diesel particle filter, the vehicle should be driven at an even speed of at least 60 km/h at engine speeds of 1
800 - 2 500 rpm for at least 15 minutes or until
the warning light goes out with the 4th or
5th gear engaged (automatic gearbox: posi-
tion S) when the traffic situation permits it. This increases the exhaust temperature and the soot deposited in the diesel particle filter is burnt. Always pay attention to the valid speed limits
.
The warning light
goes out after the successful cleaning of the diesel particle filter.
If the filter is not properly
cleaned, the warning light
does not go out and the
warning light
begins to flash. In the in
formation display* appears
Diesel-particle
filter! Owner's manual
. Afterwards the engine control unit shifts the engine into the
emergency mode, which only has a reduced po
wer output. After switching the ignition
off and on again the warning light
comes on.
Have the vehicle inspected without
delay by your specialist garage.
