The physical principle of a frontal collisionThe physical principle of a frontal a
ccident can be explained quite simply:
Motion energy, so-called kinetic energy, is
produced as soon as the vehicle is
moving, both for the vehicle and its occupants. The magnitude of this kinetic energy depends essentially on the speed at which the vehicle is travelling and on the weight of the vehicle and the occupants. The greater the speed and weight increase,
the greater the amount of energy which has to be absorbed in the event of an acci- dent. The speed of the vehicle is, nevertheless,
the most important factor. Doubling the
speed of the vehicle from 25 km/h up to
50 km/hour increases the kinetic energy
four times. The common opinion that it is possible to
support your body
in a minor accident
with your hands, is incorrect. Even in a
collision at only a low speed, the forces
acting on the body are such that it is
no longer possible to support your body.
Even if you only drive at a speed within the range from 30 km/hour to 50 km/hour, the forces which are produced on your body
in the event of an accident can easily
exceed 10.000 N (Newton). This equals a weight of one tonne (1 000 kg). In the event of a frontal collision, occupants of the car not wearing a seat belt, are thrown forward and strike in an uncontrolled way parts of the interior of the car, such as steering wheel, dash panel, windscreen,
⇒fig. 163
. The occupants of a
vehicle who have not fastened their seat belts may even be thrown out of the vehicle. This can resu
lt in fatal injuries.
It is also important that rear seat occupants fasten their seat belts as they will other- wise be thrown through the vehicle in an
uncontrolled manner in the event of an
accident A rear seat passenger who has not
fastened the seat belt is a danger not
only to himself but also fo
r those seated at the front

Important safety information regarding the use of seat beltsThe correct use of the seat belts considerably reduces the risk of injury!
WARNING
•
The belt webbing must not be jammed in-between at any point or
twisted, or chafe ag
ainst any sharp edges.
•
It is important that the belt webbing is properly routed if the seat belts
are to offer their maximum protection

bstitute for the seat belt!
The front airbag for the driver is housed in the steering wheel

The front airbag for the front passenger is housed in the dash panel above the storage compartment
⇒fig. 170
. The installation positions are each marked with
the “AIRBAG” logo. The front airbag system, in combination with
three-point safety belts, offers addi-
tional protection for the head and chest ar
ea of the driver and front passenger in
the event of a frontal colli
sion of major severity
⇒
in “Important safety informa-
tion regarding the front airbag system” on page 177. The airbag is not a substitute for the seat
belt, but is part of the complete passive
vehicle safety concept.
Please note that an airbag can only offer you optimal
protection in combination with a seat belt which is fastened
.
Apart from their normal protective function, a further task of the
seat belts
is to
also hold the driver and front passenger in
a correct seated position in the event of
a frontal collision so as to enable the fr
ont airbags to offer the maximum protection.
You should therefore always fasten the seat
belts, not only because this is required
by law, but also for safety reasons and for your own protection

In certain accident situations, the front, side and head airbag are deployed together. If the airbags are deployed, the airbags are filled with a propellant gas and inflated in front of the driver and front passenger
⇒fig. 171
. The airbags inflate in fractions
of a second and at a high speed in order to
be able to offer that additional protec-
tion in the event of an accident. The forward movement of the driver and of the front passenger is cushioned when they make
contact with the fully inflated airbag
and the risk of injury to head and chest is thus reduced. The specially developed airbag allows the gas
to flow out of the inflated airbag in a
controlled manner (depending on the load
of the particular car occupant) in order
to cushion head and chest areas. The airbag
then deflates subsequently to such an
extent, after an accident, to again provide a clear view forward. A grey white, non harmful gas is released when airbag is inflated. This is perfectly normal and is not an indication of a fire in the vehicle. The airbag develops enormous forces when triggered, which can lead to injuries if the sitting position or seated position is not correct

WARNING
•
Never transport children on the front seat of a vehicle without using a
proper restraint system. If airbags are
deployed in the event of an accident,
the child might suffer severe or even fatal injuries!•
For the driver and front passenger it is important to maintain a distance
of at least 25 cm from the steering wheel or dash panel
⇒fig. 172
. Not main-
taining this minimum distance will mean that the airbag system will not be able to properly protect you - hazard!
The front seats and the head restraints
must always also be correctly adjusted to match the body size of the occu- pant.•
It is essential to always switch off
⇒page 182, “Deactivating an airbag”
the front passenger airbag when attaching a child safety seat on the front passenger seat where the child is seated
with its back facing in direction of
travel (in some countries al
so when the child is facing the direction of travel).
If this is not done, there is a risk of
the child suffering severe or even fatal
injuries if the front passenger airbag
is deployed. In certain countries
national legal provisions also requir
e that the side or head passenger
airbags be deactivated. When transpor
ting a child on the front passenger
seat, please comply with the appropriate national regulations regarding the use of child safety seats.•
There must not by any further persons, animals or objects positioned
between the front seated occupants and the deployment area of the airbag.•
The steering wheel and the surface of
the airbag module in the dash
panel on the passenger side must not be stuck onto, covered or modified in any other way. These parts should only be cleaned with a dry cloth or a cloth moistened with water. No objects such as cup holders, mobile phone mounts, etc. may be attached to the covers of the airbag modules or be located within the immediate area.•
No modifications of any kind may be made to parts of the airbag system.
Any work on the airbag system includ
ing installing and removing system
components because of other repair
work (e.g. removing the steering
wheel) must only be carried
out by a specialist garage.

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 car 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),
•
Active driver-steering recommendation (DSR),
•
Antilock brake system (ABS),
•
Brake Assist,
•
Uphill-Start off-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 vehi
cle about its vertical axis, the lateral accel-
eration of the vehicle, the brakin
g pressure and the steering angle.
The direction which the driver wishes to ta
ke 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 exis
t, such as the car 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 re
ar 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 197. If there is a fault in the
ABS system, the ESP also does not operate. The ESP warning light lights up in the instru
ment cluster when there is a fault on the
ESP
 ⇒page 39.
Switching off You can switch the ESP off and on again
as you wish, by pressing the button
⇒ fig. 190
. The ESP warning light lights up in th
e instrument cluster when the ESP is
switched off
 ⇒page 39.
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:

when driving with snow chains
•
when driving in deep snow or on a loose surface
•
when it is necessary to rock a ca
r free 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 other assign-
ment of tyres and wheels) can influence the function of the ESP
⇒page 241,
“Accessories, changes and replacement of parts”.Electronic Differential Lock (EDL)* The electronic differential lock pr
events an individual wheel from
slipping.Models fitted with ESP are equipped with electronic differential lock (EDL). General The EDL makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditio
ns of the road surface are unfavourable.
Operating principle The EDL is activated automatically, that is
without any action on the part of the
driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors. Should only
one
drive wheel begin spinning on a slippery surface there will be an
appreciable difference in the speed of the driven wheels. The EDL function brakes the slipping wheel and the differential transmits a greater driving force to the other driven wheel. This control proces
s is also accompanied by noises.
Overheating of the brakes The EDL switches off
automatically if unusually severe
stresses exist in order to
avoid excessive heat generation in the
disc brake on the wheel which is being
braked. The vehicle can continue to be driv
en and has the same characteristics as a
vehicle not fitted with EDL. The EDL switches on again
automatically as soon as the brake has cooled down.
WARNING
•
Depress the accelerator carefully when accelerating on uniformly slip-
pery road surfaces, such as ice and sn
ow. The driven wheels might still spin
despite the EDL and affect the stability
of the vehicle - risk of an accident!
•
You should always adapt your style of driving to the condition of road
surface and to the traffic situation even
when your vehicle is fitted with EDL.
The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•
If the ABS or ESP warning light comes on,
this may also indicate a fault in the
EDL. Please have the car inspected as s
oon as possible by a specialist garage.

the brakes, on chassis or other assign-
ment of tyres and wheels) can in
