General information
Introduction
This chapter contains information on the following subjects:
Before setting off

Driving safety
8
In this section of the instructions you will find important information, tips and
notes on the subject of passive safety.
We have combined everything here which you should be familiar with, for ex-
ample, regarding seat belts, airbags, safety of children and anything similar.
You can find further information on safety concerning you and those travelling
with you in the following chapters of this Owner's Manual.
The complete on-board literature should therefore always be in the vehicle.
This applies in particular, if you rent out or sell the vehicle.
Before setting off
For your own safety and the safety of the people travelling with you, please
pay attention to the following points before setting off.
▶ Ensure that the lighting and the turn signal system are functioning properly.
▶ Ensure that the function of the wipers and the condition of the wiper blades
are free of any defects.
▶ Ensure that all of the windows offer good visibility to the outside.
▶ Adjust the rear-view mirror so that vision to the rear is guaranteed.
▶ Ensure that the mirrors are not covered.
▶ Check the tyre inflation pressure.
▶ Check the engine oil, brake fluid and coolant level.
▶ Secure all items of luggage.
▶ Do not exceed the permissible axle loads and permissible gross weight of the
vehicle.
▶ Close all doors as well as the bonnet and boot lid.
▶ Ensure that no objects can obstruct the pedals.
▶
Protect children in suitable child seats with correctly fastened seat belts
» page 20 , Transporting children safely .
▶ Adopt the correct seated position » page 8, Correct and safe seated posi-
tion . Tell your passengers to assume the correct seated position.
Driving safety
The driver is fully responsible for himself and passengers, especially children. If
your driving safety is effected, you place yourself and the oncoming traffic at
risk.
The following guidelines must therefore be observed. ▶ Do not become distracted from concentrating on the traffic situation, (e.g. by
your passengers or mobile phone calls).
▶ Never drive when your driving ability is impaired, (e.g. due to medication, al-
cohol or drugs).
▶ Keep to the traffic regulations and the permissible speed limit.
▶ Always adjust the driving speed to the road, traffic and weather conditions.
▶ Take regular breaks on long journeys (at least every two hours).
The following list contains instructions for the Passenger which, if not ob-
served, may cause serious injuries or death. ▶ Do not lean against the dash panel.
▶ Do not put your feet on the dash panel.
The following list contains instructions for all Passengers which, if not ob-
served, may cause serious injuries or death. ▶ Do not sit only on the front part of the seat.
▶ Do not sit facing to the side.
▶ Do not lean out of the window.
▶ Do not put your limbs out of the window.
▶ Do not put your feet on the seat cushion.
Correct and safe seated position

Correct seated position for the front passenger

Seat belts
Using seat belts
Introduction
This chapter contains information on the following subjects:
The physical principle of a head-on collision
12
Correct routing of seat belt
12
Fastening and unfastening seat belts
13
Seat belts that are fastened correctly offer good protection in the event of an
accident. They reduce the risk of an injury and increase the chance of survival
in the event of a major accident.
Properly fastened seat belts hold occupants to correctly set seats in the right
seat position.
Particular safety aspects must be observed when transporting children in the
vehicle » page 20 .
WARNING■
Fasten your seat belt before each journey - even when driving in town!
This also applies to other passengers - there is a danger of injury!■
Maximum seat belt protection is only achieved if you are correctly seated
» page 8 , Correct and safe seated position .
■
The seat backrests of the front seats must not be tilted too far to the rear
otherwise the seatbelts can lose their effectiveness.
WARNINGInformation on the correct routing of the belt■Always ensure that the webbing of the seat belts is properly routed. Seat
belts which are not correctly adjusted can themselves cause injuries even
in minor accidents.■
Adjust the height of the belt in such a way that the shoulder part of the
belt is roughly positioned across the middle of your shoulder - on no ac-
count across your neck.
WARNING (Continued)■ A seat belt which is hanging too loose can result in injuries as your body is
moved forward by the kinetic energy produced in an accident and is then
suddenly held firm by the belt.■
The belt webbing must not run across solid or fragile objects (e.g. specta-
cles, ball-point pens, bunches of keys etc.). Such objects can cause injury.
WARNINGInformation on dealing with the safety belts■The belt webbing must not be jammed in-between at any point or twis-
ted, or chafe against any sharp edges.■
Make sure you do not catch the seat belt in the door when closing it.
WARNINGInformation on the proper use of safety belts■No two persons (also not children) should ever use a single seat belt to-
gether.■
The lock tongue should only be inserted 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 slot of the belt tongue must not be blocked, otherwise the belt
tongue will not lock in place properly.
■
Many layers of clothing and loose clothing (e. g. a winter coat over a jack-
et) do not allow you to be correctly seated and impairs proper operation of
the seat belts.
■
Do not use clamps or other objects to adjust seat belts (e.g. for shorten-
ing the belts for smaller persons).
■
The seat belts for the rear seats can only fulfil their function reliably
when the seat backrests are correctly locked into position » page 85.
WARNINGInformation on the care and maintenance of safety belts■The belt webbing must always be kept clean. Soiled belt webbing may im-
pair proper operation of the inertia reel » page 200.■
The seat belts must not be removed or changed in any way. Do not at-
tempt to repair the seat belts yourself.

The warning lights in the instrument cluster indicate certain functions or
faults.
Some warning lights can be accompanied by acoustic signals and messages in
the display of the instrument cluster.
After switching on the ignition, some warning lights light up briefly as a func-
tion test.
If the tested systems are OK, the corresponding warning lights go out a few
seconds after switching on the ignition or after starting the engine.
Warning lights in the display
Depending on the importance the warning light
(danger) or
(warning) illu-
minate along with some of the warning lights in the list with the warning
lights.
Depending on vehicle specification, some warning lights may be displayed in
colour on the display. For example. the coolant warning lamp may be represen-
ted as follows.
▶ - Segment Display / monochromatic (“black and white”) MAXI DOT display
▶ - colour MAXI DOT displayWARNING■
Ignoring illuminated warning lights and related messages or instructions
in the display of the instrument cluster may lead to serious personal injury
or damage to the vehicle.■
If you have to stop for technical reasons, then park the vehicle at a safe
distance from the traffic, switch off the engine and switch on the hazard
warning lights » page 71. Place the warning triangle at the prescribed dis-
tance.

If you drive more efficiently this value can increase.
Average fuel consumption
The indication is calculated continuously since the last deletion of the memory.
After erasing the memory, no data will appear for the first 100 m driven.
Current fuel consumption
You can use this information to adapt your driving style to the desired fuel
consumption.
When the vehicle is stationary or slowly moving the fuel consumption is dis-
played in l/h (on models for some countries the following appears --,- km/l).
Oil temperature
If the engine oil temperature is in the range 80-110 °C, the engine operating
temperature is reached.
If the oil temperature is lower than 80 °C or above 110 °C, avoid high engine
revs, full throttle and high engine loads.
If the oil temperature is lower than 50 °C or if there is a fault in the system for
checking the oil temperature are displayed instead of the oil temperature.
