Passive Safety 128Before setting off
The driver is always fully responsible for his occupants and for the
operating safety of the vehicle.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.
•
Inspect the tyre inflation pressure.
•
Ensure that all the windows offer a good visibility to the outside.
•
Safely attach the items of luggage ⇒page 67, “Loading the luggage compart-
ment”.
•
Ensure that no objects can obstruct the pedal.
•
Adjust the mirror, the front seat and the head restraint to match your body size.
•
Point out to your occupants that the head restraints must be adjusted to match
their body size.
•
Protect the children in suitable child seats with correctly fastened seat belts
⇒page 147, “Transporting children safely”.
•
Adopt the correct seated position. Also inform your occupants to adopt the
correct seated position.
•
Fasten the seat belt correctly. Also inform your occupants to properly fasten the
seat belts ⇒page 134, “How are seat belts correctly fastened?”.
What influences the driving safety?
The driving safety is primarily determined by the style of driving and
the personal behaviour of all the occupants.The driver is fully responsible for himself and his occupants. If your driving safety is
effected, you place yourself and the oncoming traffic at risk. Please refer to the
following guidelines.•
Do not get distracted from concentrating on the traffic situation, e.g. by your
occupants or mobile phone calls.
•
Never drive when your driving ability is impaired, e.g. through medication,
alcohol, drugs.
•
Keep to the traffic regulations and the permissible speed limit.
•
Adjust the driving speed at all times to the road condition as well as to the traffic
and weather conditions.
•
Take regular breaks on long journeys - at the latest every two hours.

Passive Safety 130correctly fastened in order to provide an optimal protection for you and your
occupants.•
The front passenger must maintain a distance of at least 25 cm to the
dash panel. Not maintaining this minimum distance will mean that the
airbag system will not be able to properly protect you - hazard!
•
Always keep your feet in the footwell when the vehicle is being driven -
never place your feet on the instrument panel, out of the window or on the
surfaces of the seats. You will be exposed to increased risk of injury if it
becomes necessary to apply the brake or in the event of an accident. If an
airbag is deployed, you may suffer fatal injuries when adopting an incorrect
seated position!
•
The seat backrests must not be angled too far back when driving other-
wise this will affect proper operation of the seat belts and of the airbag
system - risk of injury!
Correct seated position for the occupants on the rear seats
Occupants on the rear seats must sit upright, keep the feet in the
footwell and must have their seat belts correctly fastened.To reduce the risk of injury in the event of a sudden braking manoeuvre or an acci-
dent, the occupants on the rear seats must observe the following.•
Adjust the head restraints so that the top edge of the head restraints are at the
same level as the upper part of your head ⇒page 129, fig. 141.
•
Fasten the seat belt correctly ⇒page 134, “How are seat belts correctly
fastened?”.
•
If you are transporting ⇒page 147, “Transporting children safely” children in
the vehicle, please use a suitable child restraint system.
WARNING
•
The head restraints must always be adjusted to match the body size, in
order to offer an optimal protection for you and your occupants.
•
Always keep your feet in the footwell when the car is being driven - never
put your feet out of the window or on the surfaces of the seats. You will be
exposed to increased risk of injury if it becomes necessary to apply the brake
or in the event of an accident. If the head airbag* is deployed and when
adopting an incorrect seated position, you are exposing yourself to an
increased risk of injury and in the event of an accident you may suffer fatal
injuries!
•
If the occupants on the rear seats are not sitting upright, the risk of injury
is increased due to incorrect routing of the seat belt.
Examples of an incorrect seated position
An incorrect seated position can lead to severe injuries or death for
the occupants.Seat belts offer their optimum protection only if the webbing of the seat belts is
properly routed. Incorrect seated positions considerably reduce the protective
functions of the seat belts and therefore increase the risk of injury due to an incor-
rect routing of the seat belt. The driver is fully responsible for himself and his occu-
pants, in particular for the children. Do not permit an occupant to adopt an incor-
rect seated position when the car is moving.
The following list contains the examples of seated positions which are dangerous
for the occupants. This list is not complete, however we would like you to get inter-
ested in this subject.
Therefore, while the car is moving never:•
stand up in the vehicle;
•
stand up on the seats;
•
kneel on the seats;
•
tilt the seat backrest fully to the back;
•
lean against the dash panel;
•
lie on the rear seat bench;
•
only sit on the front area of the seat;

Seat belts 136Taking seat belts off– Press the red button in the belt lock ⇒fig. 148. The spring force causes
the tongue of the lock to jump out.
– Guide the belt back with your hand to enable the inertia reel to wind
up the belt webbing more easily.A plastic knob in the belt webbing holds the belt tongue in a position which is easy
to get hold of.Three-point safety belt for the middle rear seatIt is used in the same way as the normal three-point seat belts on the left and right
(at front and rear). The three-point seat belt for the rear middle seat must be put on
first to allow the pelvic part of the belt to run between the belt lock for the right
three-point seat belt and the backrest, while avoiding crossing the belt webbing of
the right and middle seat belts.
WARNING
•
The three-point safety belt for the rear middle seat can only fulfil its func-
tion reliably when the backrests are correctly locked into position
⇒page 65.
Note
The vehicles of the group N1 are not equipped with the third seat belt on the rear
seats. The vehicle is only approved for four persons.Belt tensionerSafety for the driver and front passenger wearing their seat belts is enhanced by
the belt tensioners fitted to the inertia reels of the front three-point seat belts.
The fastened three-point seat belts are automatically tensioned in the event of a
frontal collision of a certain severity. The belts tensioners are also deployed if the
seat belts are not fastened.
Belt tensioners are not activated in the event of minor frontal collisions, side and
rear-end collisions, in the case of a rollover and also not in accidents in which no
major forces are produced from the front.
WARNING
•
Any work on the belt tightener system, including removal and installa-
tion of system components because of other repair work, must only be
carried out by a specialist garage.
•
The protective function of the system is only adequate for a single acci-
dent. If the belt tensioners have been deployed, it is then necessary to
replace the entire system.
•
The Owner's Manual must also be handed over to the new owner if the
vehicle is sold.Note
•
Smoke is generated when the belt tensioners are deployed. This is not an indi-
cation of a fire in the vehicle.
•
It is essential to pay attention to relevant safety regulations if the vehicle or indi-
vidual parts of the system are scrapped. Specialist garages are familiar with these
regulations and will be able to provide you with detailed information in this respect.

•
There must not be any other persons (e.g. children) or animals between
the car occupant and the deployment area of the head airbag. In addition,
none of the occupants should lean their head out of the window when
driving, or extend their arms and hands out of the window.
•
The sun visors must not be swivelled to the side windows into the
deployment area of the head airbags if any objects, such as ball-point pens
etc. are attached to them. This might result in injuries to the occupants if the
head airbag is deployed.
•
Installing impermissible accessories in the area of the head airbags may
considerably impair the protection offered by the head airbag in the event of
it being deployed. When the deployed head airbag is inflated, parts of the
accessories fitted may in certain circumstances be thrown into the interior
of the car and cause injuries to the occupants ⇒page 204.
•
Any work on the head airbag system including installing and removing
system components because of other repair work (e.g. removing headliner)
must only be carried out by a specialist garage.
Deactivating airbagsDeactivating airbags
If any airbags have been deactivated, switch them on again as soon
as possible so that they are able to again provide their proper protec-
tion.There is the technical means installed within your vehicle to switch off the front,
side* or head* airbag (take out of commission).
This is why you should have the deactivation of the airbags carried out by a
specialist garage.On vehicles equipped with the switch for deactivation of the airbags, you can deac-
tivate the front passenger airbag or passenger side airbag by means of this switch
⇒page 146.
Deactivation of airbags is envisaged only for particular instances, such as if:
•
You must in exceptional cases use a child seat on the front passenger seat
where the child is seated with its back to the direction of travel (in some countries
this must be in the direction of travel due to other legal regulations applying)
⇒page 147, “Important safety information regarding the use of child safety seats”;
•
you are not able to maintain the distance of at least 25 cm between middle of
steering wheel and chest, despite the driver seat being correctly adjusted;
•
special attachments are required in the area of the steering wheel because of a
physical disability;
•
you have installed other seats (e.g. orthopaedic seats without side airbags).
Monitoring the airbag system
The functionality of the airbag system is also monitored electronically when one
airbag has been switched off.
If the airbag was switched off using diagnostic equipment:
•
The airbag indicator light in the instrument cluster lights up for about 3 seconds
after switching on the ignition and then flashes after that for about 12 seconds.
If the airbag was switched off using the airbag switch* on the side of the dash
panel:
•
the airbag indicator light in the instrument cluster comes on for about 3
seconds each time the ignition is switched on;
•
if the airbags are switched off, this is indicated in the middle of the dash panel
by the lighting up of the indicator light
⇒page 146, fig. 158.
Note
A specialist garage will provide you with information on whether national legisla-
tion in your country allows airbags in your vehicle to be deactivated, and which
ones.

Transporting children safely 154
WARNING
•
The locking eyes have just been developed for child safety seats which
use the “ISOFIX” system. You should therefore never attach other child
safety seats, seat belts or objects to the locking eyes - hazard!
•
Ask a specialist garage whether a child seat which you bought for
another vehicle is recommended for use in your vehicle before using a child
seat with “ISOFIX” system.
•
Certain child seats which use the “ISOFIX” system can be attached with
standard three-point seat belts. Please pay close attention to instructions
from the manufacturer of the child safety seat when installing and removing
the seat.Note
•
Child seats which use the “ISOFIX” system are currently available for children
weighing up to about 18 kg. This corresponds to an age range up to 4 years.
•
The child seats can also be fitted with the “Top Tether” system ⇒page 154.
Attaching child seat using the “Top Tether” system
On vehicles with divided rear seats* the seats are equipped with the attachment
system “Top Tether” for enhancing the safety of the children when being trans-
ported ⇒fig. 168.
On vehicles with non divided rear seats* the lashing eyes in the luggage compart-
ment are used to fasten the child seats with the system “Top Tether” ⇒fig. 169.
Always perform the installation and removal as stated in the instructions from the
manufacturer of the child seat.
WARNING
•
Attach the child seats with the “Top Tether” system only to the points
provided for this purpose ⇒fig. 168.
•
On no account should you equip your vehicle, e.g. mount screws or other
anchorage points.
•
Pay attention to the important safety information regarding the use of
child seats ⇒page 147.Note
Store the remaining part of the belt for the “Top Tether” system in a textile pocket,
which is located at the child seat.

Technical Data
Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral
The ESP aids you maintain control of your vehicle in situations in borderline driving
situations such as when negotiating a curve too fast. The risk of skidding is reduced
and your vehicle thus offers greater driving stability depending on the conditions of
the road surface. This occurs at all speeds.
The following systems are integrated into the electronic stability programme:•
Electronic Differential Lock (EDL);
•
Traction control system (TCS);
•
Antilock brake system (ABS);
•
Brake Assist.Operating principle
The ESP switches on automatically when the engine is started and then conducts a
self-test. The ESP control unit processes data from the individual systems. It also
processes additional measurement data which are supplied by highly sensitive
sensors: the rotational velocity of the vehicle about its vertical axis, the lateral accel-
eration of the vehicle, the braking pressure and the steering angle.
The direction which the driver wishes to take is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual
behaviour of the vehicle. If differences exist, such as the vehicle beginning to skid,
the ESP will automatically brake the appropriate wheel.
The car is stabilised again by the forces which take effect when the wheel is braked.
Intervention into the brake system takes place primarily on the outer front wheel of
a vehicle which tends to oversteer (tendency for the rear of the vehicle to break
away) while occurs this is on the inner rear wheel of a vehicle which tends to under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied
by noises.
The ESP operates in combination with the ABS ⇒page 159, “Antilock brake system
(ABS)*”. If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light lights up in the instrument cluster when there is a fault on the
ESP
⇒page 32.
Switching off
You can switch the ESP off and on again as you wish, by pressing the button
⇒fig. 170. The ESP warning light lights up in the instrument cluster when the ESP is
switched off
⇒page 32.
The ESP should normally always be switched on. It may be good practice in certain
exceptional cases, such as when you wish to have wheel slip, to switch off the
system.
Examples:

Intelligent Technology 156•
when driving with snow chains;
•
when driving in deep snow or on a loose surface;
•
when it is necessary to rock a vehicle when it has become stuck.
then you should switch on the ESP again.
WARNING
It is also not possible for the ESP to overcome the physical limits of the
vehicle. Even if a vehicle fitted with ESP you should still always adapt your
style of driving to the condition of the road surface and the traffic situation.
This particularly applies when driving on slippery and wet roads. The
increased safety offered must not tempt you to take greater risks than other-
wise - risk of an accident!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the ESP. Differing rolling circumferences of the tyres can lead to an
undesirable reduction in the engine output.
•
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 ESP ⇒page 204,
“Accessories, changes and replacement of parts”.
Traction control system (TCS)*
The traction control system prevents the driven wheels from spinning
when accelerating.General
The TCS makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The TCS switches on automatically when the engine is started and then conducts a
self-test. The system monitors the speeds of the driven wheels with the aid of the
ABS sensors. If the wheels are spinning, the force transmitted to the road surface is
automatically adapted by reducing the engine speed. This occurs at all speeds.
The TCS operates in combination with the ABS ⇒page 159, “Antilock brake system
(ABS)*”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light lights up in the instrument cluster when there is a fault on the
TCS
⇒page 31.
Switching off
You can switch the TCS off and on again as you wish by pressing the button
⇒fig. 171. The TCS warning light lights up in the instrument cluster when the TCS is
switched off
⇒page 31.
