A phone phonebook is part of the mobile phone preinstallation with voice control.
In the phone phonebook there are 1 500 free memory locations available. This
phone phonebook can be used in line with the mobile telephone.For vehicles fitted with multi-functional module*, the operation is performed via
the function buttons on the module ⇒page 113.
Furthermore the volume can be changed individually at any time with the button
for setting the radio or on vehicles fitted with multi-functional module* with func-
tion 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 pressing the PTT button. You can also end the
dialogue with the voice command CANCEL.
The dialogue is always automatically ended after carrying out an operation, e.g.
after erasing the name from the phonebook.
The dialogue of the incoming call is immediately interrupted and you can accept
the call by pressing the button
.
If a voice command is not detected, the system answers with “Sorry?” and a new
entry can be performed. 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.

Technical Data For your own safety and to reduce the risk of injury in the event of an accident, we
recommend the following setting.
•
Adjust the steering wheel so that the distance between the steering wheel and
your chest is at least 25 cm ⇒page 128, fig. 140.
•
Position the driver seat in the forward/back direction so that you are able to fully
press the pedals with your legs at a slight angle.
•
Adjust the seat backrest so that you are able to reach the highest point of the
steering wheel with your arms at a slight angle.
•
Adjust the head restraint so that the top edge of the head restraint is at the same
level as the upper part of your head ⇒fig. 141.
•
Fasten the seat belt correctly ⇒page 134, “How are seat belts correctly
fastened?”.
Driver seat adjustment ⇒page 62, “Adjusting the front seats”.
WARNING
•
The front seats and the head restraints must always be adjusted to match
the body size of the seat occupant as well as the seat belts must always be
correctly fastened in order to provide an optimal protection for you and your
occupants.
•
The driver must maintain a distance of at least 25 cm to the steering
wheel ⇒page 128, fig. 140. Not maintaining this minimum distance will mean that the airbag system will not be able to properly protect you -
hazard!
•
When driving, hold the steering wheel with both hands firmly on the
outer edge in the 9 o'clock and 3 o'clock position. Never hold the steering
wheel firmly in the 12 o'clock position or in another way (e.g. in the middle
of the steering wheel or at the inner steering wheel edge). In such cases,
injuries to the arms, the hands and the head can occur when the driver
airbag is deployed.
•
Ensure that there are no objects in the footwell as any objects may get
behind the pedals during a driving or braking manoeuvre. You would then
no longer be able to operate the clutch, to brake or accelerate.
Correct seated position for the front passenger
The front passenger must maintain a distance of at least 25 cm from
the dash panel so that the airbag offers the greatest possible safety
when an airbag is deployed.For the safety of the front passenger and to reduce the risk of injury in the event of
an accident, we recommend the following setting.•
Adjust the front passenger seat as far as possible to the rear.
•
Adjust the head restraint so that the top edge of the head restraint is at the same
level as the upper part of your head ⇒fig. 141.
•
Fasten the seat belt correctly ⇒page 134, “How are seat belts correctly
fastened?”.

Technical Data
The physical principle of a frontal collisionThe physical principle of a frontal accident 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. 143. 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 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 for those seated at the front ⇒fig. 144.
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 134, “How are seat belts
correctly fastened?”.

Technical Data
When are the airbags deployed?The airbag system is designed in such a way that the driver and the front passenger
airbag* are deployed in the event of a frontal collision of major severity.
In the case of a violent side crash, the side airbag* in the front seat and the head
airbag* on the side on which the collision occurs are deployed.
It is also possible under certain special accident situations that the front as well as
the side airbags and head airbags* are deployed at the same time.
The airbags are not deployed in the case of minor frontal and side collisions, in the
case of rear-end collisions and vehicle rollover.
Deployment factors
It is not possible to state globally which deployment conditions apply to the airbag
system in every situation as the circumstances which exist in the case of accidents
vary greatly. An important role in this case, for example, is played by factors such as
the type of object against which the vehicle impacts (hard, soft), the angle of impact,
the vehicle speed etc.
A decisive factor for the deployment of the airbags is the deceleration which occurs
during a collision. The control unit analyses the nature of the collision and activates
the relevant restraint system. If the vehicle deceleration which occurs and is meas-
ured during the collision remains below the prescribed reference values specified
in the control unit, the airbags are not deployed although the vehicle may well
suffer severe damage to the bodywork as a consequence of the accident.
The airbags are not deployed if:•
ignition is switched off;
•
a minor frontal collision;
•
a minor side collision;
•
a rear-end collision;
•
Rollover of the vehicle.Note
•
A grey white or red, non harmful gas is released when airbag is inflated. This is
perfectly normal and is not an indication of a fire in the vehicle.
•
In the event of an accident in which the airbags are deployed:
−the interior lighting comes on (if the switch for the interior light is in the door
contact position),
−the hazard warning light is switched on;
−All the doors are unlocked.

Airbag system 140The front airbag for the driver is housed in the steering wheel ⇒page 139, fig. 149.
The front airbag for the front passenger* is housed in the dash panel above the
storage compartment ⇒page 139, fig. 150. 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 area of the driver and front passenger in
the event of a frontal collision of major severity ⇒ in “Important safety informa-
tion regarding the front airbag system” on page 141.
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 front 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 ⇒page 132, “Why
seat belts?”.
Caution
The dash panel must be replaced after the front passenger airbag has been
deployed.
Function of the front airbags
Risk of injury to the upper part of the body is reduced by fully inflated
side airbags.The airbag system is designed in such a way that the driver and front passenger
airbag* are deployed in the event of a frontal collision of major severity.
In certain accident situations, the front, side and head airbag are simultaneously
deployed.
If the airbags are deployed, the airbags are filled with a propellant gas and inflated
in front of the driver and front passenger ⇒fig. 151. 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 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.

Important safety information regarding the front airbag system
Correct use of the airbag system considerably reduces the risk of
injury!
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. 152. 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 145, “Deactivating airbags” 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 also 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 require that the side or head passenger
airbags be deactivated. When transporting 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 including 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.
•
Never carry out changes on the front bumper or on the body.
•
Never place any objects on the surface of the dash panel on the front
passenger side.
