While connecting the mobile phone with the hands-free system by means of Blue-
tooth
®, no other phone can be connected wi th the hands-free system via Blue-
tooth®.
Up to seven mobile phones and four mu ltimedia units can be connected by the
hands-free system via Bluetooth
® whereby only one mobile phone or multimedia
unit can communicate simultaniously via Bluetooth® with the hands-free system.
If an eighth mobile phone is connected to the handsfree-system, then the tele-
phone, which has not been used together with the handsfree system for the longest
period, is disconnected by means of Bluetooth
®.
Establish Bluetooth
® connection
After switching on the ignition, the Blue tooth connection is automatically estab-
lished for the already adapted mobile phone
12). Check on the mobile unit if the
automatic connection was established.
Disconnect Bluetooth
® connection
After withdrawing the ignition key, the Bluetooth® connection is disonnected.
WARNING
•Pay attention primarily to the traffic si tuation! As the driver you are fully
responsible for road safety. Use the telephone system only to such an extent,
so that you are in full control of your vehicle at any time - risk of accident!
•In the event of air transport, the Bluetooth® function of the handsfree-
system must be switched off by a specialist garage!
Caution
Taking the mobile phone out of the adapter during the call can lead to interruption
of the connection. When taking out the mobile phone, the connection to the
factory-fitted antenna is interrupted, this reduces the quality of the transmitting
and receiving signal. This might result additionally in harmful radiation from the
mobile phone in the interior of the ve hicle and the charging of the telephone
battery is interrupted.
Note
•Not valid for all mobile phones which enable a communication via Bluetooth®.
•Please operate your mobile phone exclusively with a suitable adapter, in order
to keep a low radiation in the vehicle.
•Inserting the mobile phone into the adapter ensures an optimal sending and
receiving power and offers at the same ti me the advantage of the battery charging.
•Note that the range of the Bluetooth® connection to the handsfree-system is
limited to the vehicle interior. The range is dependent on local factors, e.g. obstacles
between the devices and interferences with other devices. If your mobile phone is
e.g. in a jacket pocket, this can lead to difficulties when establishing the Bluetooth
®
connection with the handsfree-sy stem or the data transfer.
Erase the list of connected units
Erase previously connected mobile or multimedia units
– Switch on the ignition. A connectio n to a mobile or multimedia unit
must not be established.
– Press the button SOS on the adapter or the button
on the multi-
function steering wheel* for more than 10 seconds.
– Erasing is confirmed with an audible signal.

Note
In the memory of the control unit, up to three users can be stored, whereby the
handsfree-system can only communicate actively with one user. In the case of
mutual connection with a fourth mobile phone, you must erase one user.
•If the telephone book of the mobile phone contains more than 1 000 entries,
the system announces a failure while loading the telephone book .
•When connecting to the control unit, follow the instructions on your mobile
phone.
•Note that the range of the Bluetooth® connection to the handsfree-system is
optimized in the vehicle interior. The rang e is dependent on local factors, e.g.
obstacles between the devices and interferences with other devices.
Operation of the telephone on the multifunction steering wheel*
The driver can set the basic functions of the telephone by simply operating the
buttons located on the steering wheel so th at he can concentrate on the traffic situ-
ation without being distracted as little as possible by operating the telephone
⇒ fig. 142 .
This applies only if your vehicle has been equiped with the telephone preinstalla-
tion at the factory.
If the side lights are switched on, the buttons on the multifunction steering wheel
are illuminated.

The physical principle of a frontal collision
The 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 uncontrolle d way parts of the interior of the car,
such as steering wheel, dash panel, windscreen, ⇒fig. 148 . 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 ⇒fig. 149 .
Important safety information regarding the use of
seat belts
The 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 156, “How are seat belts
correctly fa stened?”.

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 228,
“Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDS)*
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 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
•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.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign-
ment of tyres and wheels) can in fluence the function of the EDL ⇒page 228,
“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 conditio ns 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
automatically adapted by redu cing the engine speed. This occurs at all speeds.
The TCS operates in combination with the ABS ⇒page 183. The TCS will not func-
tion if a fault exists in the ABS system.
The TCS warning light ⇒page 31 lights up in the instrument cluster when there is a
fault on the TCS.
Switching off
You can switch the TCS off and on again as you wish by pressing the button
⇒ fig. 176 . The TCS warning light ⇒page 31 lights up in the instrument cluster
when the TCS is switched off. 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 car free 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 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 in fluence the function of the TCS ⇒page 228,
“Accessories, changes and replacement of parts”.
Driver-steering recommendation*
The driver-steering recommendation is an additional function of the electronic
stability programme (ESP). This function indicates to the driver in critical situations
by means of slight steering wheel impulses the direction evaluated by the system,
in which the vehicle must be steered, so that it stabilizes. The driver-steering
recommendation is active when braking shar ply on different road surfaces and on
the right and left vehicle side.

Wheels and Tyres
226
Winter tyres
The handling of your vehicle will be signi ficantly improved when driving on wintry
roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow
and at temperatures below 7 °C because of their construction (width, rubber blend,
tread pattern). This particularly applie s to vehicles which are equipped with low-
profile tyres or high-speed tyres (code index H or V on wall of tyre).
Winter tyres must be mounted on all four wheels to obtain the best handling char-
acteristics.
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 in flated to 20 kPa (0.2 bar) more than is
the case for summer tyres ⇒page 222, fig. 195 .
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 224,
⇒ .
You can fit winter tyres of a lower speed category 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 ve hicle 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 222.
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 information 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 tempera-
tures 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.
Unidirectional tyres*
The direction of rotation of the tyres is marked by arrows on the wall of the tyre.
This indicates the direction of rotation of the tyre, and it is essential that the tyres
are fitted on to run in this direction. On ly then are the tyres able to provide the
optimal properties in terms of grip, lo w noise, wear-and-tear and aquaplaning.
Should it be necessary to fit on a spare wheel in exceptional cases with a tyre not
dedicated to the running direction or in o pposite running direction, please adopt a
cautious style of driving as the tyre is no longer able to provide optimal grip and
handling in such a situation. This particul arly important on wet roads. Please refer
to the notes ⇒page 231, “Spare wheel”.
You should have the defective tyre replac ed as soon as possible and restore the
correct direction of rotation on all tyres
Snow chains
Snow chains must only be mounted on the front wheels.
