Table of Contents Using the system Safety Driving Tips General Maintenance Breakdown assistance Technical data
Layout 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 index
The 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 particu-
lar moment is highlighted at the bottom right of the page.
The Table of contents is arranged according to the chapters and the detailed Sub-
ject index at the end of the Owner's Manual helps you to rapidly find the informa-
tion you are looking for.
Sections The majority of Sections apply to all models.
Since there is a wide range of different equipment and options available it is clear-
ly unavoidable, despite dividing the contents into sections, that mention may be
made of equipment which is not fitted to your vehicle.
Brief information and instructions Each 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 let-
ters) which explains to you in a straightforward way the action you have to take.
Work steps which have to be carried out are illustrated with a hyphen.
Direction indications
All direction indications such as
“left”, “right”, “front”, “rear” relate to the direction
of travel of the vehicle.
Explanation of symbols End of a section.
£ The section is continued on the next page.
Notes
All four kinds of notes, which are used in the 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 frequently 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 possibility of damage to your vehicle
(e.g. damage to gearbox), or points out general risks of an accident. For the sake of the environment
An Environmental note draws your attention to environmental protection as-
pects. 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. 6

Engine revolutions counter The red zone of the rev counter scale

⇒ fig. 2 indicates the range in which the
engine control unit begins to limit the engine speed. The engine control unit re-
stricts the engine speed to a steady limit value.
Shift into the next higher gear or select the selector lever position D of the auto-
matic gearbox before reaching the red zone of the rev counter scale.
Avoid high engine speeds during the driving time and before the engine has been
warmed up to operating temperature ⇒ page 162
. For the sake of the environment
Shifting to a higher gear in good time helps to reduce the fuel consumption, mini-
mises operating noise levels, protects the environment and contributes to a lon-
ger life and reliability of the engine.
Speedometer Warning against excessive speeds
An acoustic warning signal will sound when the vehicle speed exceeds 120 kilo-
metres per hour. The acoustic warning signal will switch off again when the vehi-
cle speed goes below this speed limit.4 5

This function is only valid for some countries.
Coolant temperature gauge The coolant temperature gauge
4 ⇒ fig. 2
operates only when the ignition is
switched on.
Please pay attention to the following guidelines regarding temperature ranges in
order to avoid damage to the engine:
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 temperature. 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 cluster 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. Please refer to the guide-
lines ⇒ page 26, Coolant temperature/Coolant quantity . WARNING
Pay attention to the warning notes ⇒ page 190
, Working in the engine com-
partment before opening the bonnet and inspecting the coolant level. CAUTION
Additional headlights and other attached components in front of the fresh air inlet
impair the cooling efficiency of the coolant. There is then a risk of the engine
overheating at high outside temperatures and high engine loads!

provides you with data (depending on the equipment installed in the vehicle) re-
lating to the radio, mobile phone, multi-functional indicator, radio navigation sys-
tem, the unit connected to the MDI input and the automatic gearbox.
Certain functions and operating conditions are always being checked on the vehi-
cle when the ignition is switched on and also while driving.
Functional faults, if required repair work and other information are indicated by
red symbols ⇒ page 19 and yellow symbols ⇒
