Universal telephone preinstallation GSM II*
Introduction
This enables you to make full use of the advantages of a normal carphone (“hands-
free system - Hands Free” using a micropho ne integrated in the vehicle, optimal
transmission of signals using an external aerial
15) etc.). The equipment includes
also the voice control. The telephone is connected by means of the Bluetooth®
technology ⇒page 144, “Bluetooth®”. On vehicles fitted with a telephone
mount*, it is also possible to establish the connection via the interface of the
adapter
16) ⇒ page 145, “Operating telephone calls with the aid of the adapter*.”.
A phone phonebook is part of the mobile ph one preinstallation with voice control.
In the phone phonebook there are 1500 free memory locations available. This
phone phonebook is independent of the appliance used for the mobile phone.
Furthermore the volume can be changed individually during the call at any time
with the button for setting the radio* or on vehicles fitted with multifunction
steering wheel* with function buttons on the steering wheel.
If the system answers with the voice response “ Telephone is not ready”, please
check the operating state of the telephone as follows:
•Is the telephone switched on?
•Is the PIN code entered?
Dialogue
The period, in which the telephone system is ready to receive voice commands and
carry out the voice commands, is called DIALOGUE. The system gives audible feed-
back and guides you if necessary through the relevant functions. You can start or
end the dialogue at any time by pres sing the PTT button on the adapter*
⇒ page 145 or on the multifunction steering wheel* ⇒page 146.
The dialogue is always automatically ended after carrying out an operation, e.g.
after erasing the name from the phonebook. When receiving an incoming call, the dialogue is immediately interrupted and you
can accept the call by pressing the button
on the multifunction steering wheel*
⇒ page 146 or by pressing the button for receiving a call directly on your tele-
phone.
If a voice command is not detected, the system answers with “ Sorry?” and a new
entry can be performed. After the 2nd error the system repeats the aid. After the 3rd
error the answer “ Cancel” is given and the dialogue is ended.
Optimum understanding of the voice commands depends on the following
factors:
•Speak with a normal tone of voice without intonation and excessive voice
pauses.
•Avoid insufficient articulation.
•Close the doors, windows and sliding roof, in order to reduce or stop disturbing
exterior noise.
•It is recommended to speak louder at higher speeds, so that the tone of your
voice is louder than the increased surrounding noise.
•During the dialogue avoid additional noise in the vehicle, e.g. simultaneously
talking occupants.
•Do not speak, if the system makes an announcement.
•The microphone for voice control is direct ed to the driver and front passenger.
Therefore the driver and the front passenger can operate the equipment.
WARNING
Pay attention primarily to the traffic situation! As the driver you are fully
responsible for road safety. Use the tele phone system only to such an extent,
so that you are in full contro l of your vehicle at any time.
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 a dditionally in harmful radiation from the

WARNING
Even with this additional function the vehicle cannot be steered automati-
cally! The driver is furthermore fully reponsible for the steering of the
vehicle!
Brakes
What has a negative effect on braking efficiency?
Wear-and-tear
Wear-and-tear to the brake pads 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 neces-
sary to have the thickness of the brake pads inspected 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 under certain condi-
tions 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 be moist or even have a coating of ice on them in winter. You
should dry the brakes as soon as possib le (by applying and releasing the brakes
several times, if the road conditions and the traffic situation allows it).
There also may be a certain delay before the full braking efficiency is available when
driving on roads which have been treated wi th road salt if you have not used the
brakes for some considerable time beforeha nd. The layer of salt on the brake discs
and brake pads must first be rubb ed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on th e bake pads occur if the vehicle has been
parked for a long period and if you do not make much use of the braking system.
We recommend cleaning the brake discs by firmly applying the brakes at a fairly
high speed if you do not make much use of the braking system or if surface corro-
sion is present ⇒. Faults in the brake surface
If you notice that the braking distance
has suddenly become longer and that the
brake pedal can be depressed further, it is possible that a brake circuit of the dual-
circuit brake system has failed. Drive, in such cases, to the nearest specialist garage
without delay in order to have the problem rectified. Drive at a reduced speed while
on your way to the dealer and adapt your style of driving to the higher brake pedal
pressure required.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The
level of the brake fluid is monitored electronically ⇒page 40, “Brake system ”.
WARNING
•Only apply the brakes for the purpos e of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users
in jeopardy.
•When retrospectively mounting a front spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced
otherwise the braking system could run too hot.
•Allow for the fact that new brake pads do not achieve their full braking
efficiency until approximately 200 kilo metres. New brake pads must be first
“run in” before they develop their optimal friction force. You can, however,
compensate for this slightly reduced braking force by increasing the pres-
sure on the brake pedal. This guidelin e also applies to any new brake pads
installed at a future date.
Caution
•Never allow the brakes to ru b by applying slight pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a longer
braking distance and excessive wear.
•Before negotiating a steep downhill sect ion, please reduce your speed, shift
down into the next lower gear (manual ge arbox) or select a lower driving stage
(automatic gearbox). This enables you to make full use of the braking power of the

Start engine
It is important to connect the jump -start cables in the correct order.
Connecting positive terminals
– Attach one end to the positive terminal ⇒fig. 230 of the
discharged battery .
– Attach the other end to the positive terminal of the battery supplying the power .
Connecting negative term inal and engine block
– Attach one end to the negative terminal of the battery supplying
the power .
– Attach the other end to a solid metal part which is connected firmly to the engine block, or to the engine block itself.
Starting engine
– Start the engine of the vehicle providing current and run the engine at idling speed.
– Now start the engine of the vehicle with the discharged battery. – Interrupt the attempt at starting an engine after 10 seconds if it does
not start right away and wait for about 30 seconds before repeating
the attempt.
– Disconnect the cables on the engine in exactly the reverse order they
were connected up.
WARNING
•The non-insulated parts of the terminal clamps must never make contact
with each other. Furthermore, the cable connected to the positive terminal
of the battery must not come into contact with electrically conducting parts
of the vehicle - risk of a short circuit!
•Do not affix the jump starting cables to the negative terminal of the
discharged battery. There is the risk of detonating gas seeping out the
battery being ignited by the strong spark which results from the engine
being started.
•Run the jump-start cables so that th ey cannot be caught by any rotating
parts in the engine compartment.
•Do not bend over the batteries - risk of caustic burns!
•The vent screws of the battery cells must be tightened firmly.
•Keep any sources of ignition (naked flame, smouldering cigarettes etc.)
away from the battery - risk of an explosion!
