Technical Data
The physical principle of a frontal collisionThe physical principle of a frontal ac cident 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 accident. 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 long
er 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, occupant s 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, da sh panel, windscreen, fig. 109 . The occupants of a vehicle who
have not fastened their seat belts may even be thrown out of the vehicle. This can
result in fatal injuries.
It is also important that rear seat occupants fasten their seat belts as they will otherwise
be thrown through the vehicle in an uncontr olled 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 for those seated at the front fig. 110 .
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 against any sharp edges.

It is important that the belt webbing is properly routed if the seat belts are
to offer their maximum protection page 104, “How are seat belts correctly
fastened?”.

No two persons (also not children) should ever use a single seat belt
together.

The maximum protection which seat belts can offer is only achieved if you
are correctly seated page 98, “Correct seated position”.

124WARNING
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 partic-
ularly applies when driving on slippery and wet roads. The increased safety
offered must not tempt you to take greater risks than otherwise - risk of an acci-
dent!
Note

All four wheels must be fitted with the same tyres in order to achieve problem-free
operation of the ESP. Differing rolling circum ferences of the tyres can lead to an unde-
sirable reduction in the engine output.

Changes to vehicle (e.g. on engine, on th e brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the ESP page 166, “Accesso-
ries, changes and replacement of parts”.
Electronic Differential Lock (EDL)*
The electronic differential lock prev ents an individual wheel from slip-
ping.Vehicles fitted with ABS* can be 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 conditions of the road surface are unfavourable.
Operating principle
The EDL is activated automaticall y, 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 greate r driving force to the other driven wheel.
This control process is also accompanied by noises. Overheating of the brakes
The EDL switches off automatica
lly if unusually severe stresses exist in order to avoid
excessive heat generation in the disc brak e on the wheel which is being braked. The
vehicle can continue to be driven 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

Carefully depress the accelerator when accelerating on uniformly slippery
road surfaces, such as ice and snow. Th e 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 warning light comes on, this may also indicate a fault in the EDL. Please
have the vehicle inspected as soon as possible by a specialist garage.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the EDL page 166, “Accesso-
ries, changes and replacement of parts”.

Technical Data
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 th e 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 auto-
matically adapted by reducing the engine speed. The system operates at all speeds.
The TCS operates in combination with the ABS page 126, “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 instru ment 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. 135 .
The TCS warning light lights up in the instru ment cluster when the system is switched
off page 31.
The TCS 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 vehicle when it has become stuck.
then you should switch on the TCS again.
WARNING
You should always adjust your style of driving to the conditions of the road
surface and the traffic situation. The increased safety offered must not tempt
you to take greater risks than otherwise - risk of an accident!
Note

All four wheels must be fitted with the same tyres in order to achieve problem-free
operation of the TCS. Differing rolling circumferences of the tyres can lead to an unde-
sirable reduction in the engine output.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the TCS page 166, “Accesso-
ries, changes and replacement of parts”.
BrakesWhat has a negative effect on braking efficiency?Wear-and-tear
Wear-and-tear to the brake pa ds is greatly dependent on the operating conditions of
the vehicle and your style of driving. Particularly if you drive a great deal in towns and
over short distances or if you adopt a sporty style of driving, it may be necessary to
have the thickness of the brake pads insp ected at a specialist garage between the
service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect un der certain conditions
such as when driving through water, during heavy rain showers or after the vehicle has
been washed in an automatic vehicle wash , since the brake discs and brake pads may

Wheels and Tyres
164
Winter tyres must be mounted on all four wheels to obtain the best handling charac-
teristics.
You must only fit those types of winter tyre which are approved for your vehicle. The
permissible sizes of winter tyres are stated in your vehicle documents. Approvals
may differ because of national legislation.
Please remember that the tyres should be inflated to 20 kPa (0.2 bar) more than is the
case for summer tyres page 160, fig. 153.
Winter tyres no longer offer the same winter performance once the tyre tread has
worn down to a depth of about 4 mm.
Ageing also causes winter tyres to lose most of their winter performance properties -
even in cases where the remaining tread depth is still clearly more than 4 mm.
Speed restrictions apply to winter tyres as well as to summer tyres page 162,
 .
You can fit winter tyres of a lower speed ca tegory to your vehicle provided that you
also do not drive faster than the permissible maximum speed for such tyres, even if the
possible maximum speed of your vehicle is higher. The corresponding tyre category
can damage the tyres when exceeding the permissible maximum speed.
Please pay attention to the notes if you decide to fit winter tyres page 160.
You can also fit so-called “all-year tyres” instead of winter tyres.
Please contact your specialist garage if there are any points which are not clear who
will be able to provide you with inform ation regarding the maximum speed for your
tyres.
WARNING
You must on no account drive your car at more than the permissible maximum
speed for your winter tyres - risk of an accident resulting from tyre damage and
loss of control over your car.
For the sake of the environment
Fit your summer tyres on again in good time since summer tyres offer you better grip
and handling on roads which are free of snow and ice as well as ar temperatures below 7 °C - the braking distance is shorter, there is less tyre noise, tyre wear is reduced and
fuel consumption is reduced.
Note
Please observe the various differing legal requirements regarding tyres.Snow chainsSnow chains must only be mounted on the front wheels.
When driving on wintry roads, snow chains
improve not only traction, but also the
braking performance.
For technical reasons, it is only permissi ble to fit snow chains with the following
wheel/tyre combinations.
Only use fine-link snow chains . They must not project more than 15 mm - including
the chain lock.
Remove the full wheel trims if you wish to fit snow chains to the wheels.
Observe the national legal requirements re lating to the maximum vehicle speed with
snow chains.
WARNING
Please pay attention to the information in the supplied fitting instructions of
the snow chain manufacturer.
