The START-STOP system helps you to save fuel while at the same time reducing
harmful exhaust emissions and CO 2 emissions.
The function is automatically activated each time the ignition is switched on.
In the start-stop mode, the engine automatically switches to the vehicle's idle
phase, e.g. when stopped at traffic lights.
Information regarding the current state of the
START-STOP system is indicated in
the display of the instrument cluster.
Automatic engine shut down (stop phase)
› Stop the vehicle (where necessary, apply the handbrake).
› Take the vehicle out of gear.
› Release the clutch pedal.
Automatic renewed engine restart (start phase).
› Depress the clutch pedal.

Starting-off and Driving

WARNING
■ The brake servo unit and power steering only operate if the engine is run-
ning.
■ Never let the vehicle roll with the engine switched off. CAUTION
If the START-STOP system is used at very high outside temperatures over a very
long period of time, the vehicle battery can be damaged. Note
■ Changes to the outdoor temperature can have an effect on the internal temper-
ature of the vehicle battery even after several hours. If the vehicle remains out-
doors for a long time in minus temperatures or in direct sunlight, it can take sev-
eral hours until the internal temperature of the vehicle battery reaches a suitable
temperature for proper operation of the
START STOP system.
■ In some instances it may be necessary to start the engine manually with the ig-
nition key (e.g. when the seat belt is not inserted or the driver's door is opened in
Stop mode for more than approx. 30 seconds). ÐCity Safe Drive

Special driving situations 68
The City Safe Drive system uses the laser sensor » Fig. 70 – to take readings
about the traffic situation in front of the vehicle at a range of around 10 metres (11
yards) » Fig. 70 – in a vehicle speed range of 5 - -30
km/h (3 - -19 mph).
If the driver does not respond to an imminent collision, the City Safe Drive system
can automatically apply the brakes to the vehicle to prevent a possible collision.
If the City Safe Drive system is currently slowing the vehicle down automatically,
the warning light will flash quickly .
Automatic braking interventions can be terminated by pressing the clutch, accel-
erator or by moving the steering wheel.
If the City Safe Drive system is not currently available, or if there is a system fault,
the warning light will flash slowly .
The following conditions cause the City Safe Drive system to become not availa-
ble.
› Taking bends tightly.
› When fully pressing down the accelerator pedal.
› When the City Safe Drive system function is switched off/faulty.
› When the laser sensor is dirty, concealed or has overheated.

› In the event of snow, heavy rain or fog.
› When vehicles are travelling side by side.
› When vehicles are crossing.
› When vehicles are approaching in the same lane.
› When the vehicles are very dirty and have a low level of reflection.
› With high levels of dust. WARNING
■ The
City Safe Drive system cannot exceed physical and system-defined lim-
its. The added convenience of the City Safe Drive system must never give you
a reason to takes risks with regard safety. The driver is always the one re-
sponsible for braking in time.

74 Safety

What influences the driving safety?
First read and observe the introductory information and safety warn-
ings on page 74.
The driver is fully responsible for himself and his occupants. If your driving safety
is effected, you place yourself and the oncoming traffic at risk.
The following guidelines must therefore be observed. › Do not get distracted from concentrating on the traffic situation, e.g. by your
passengers or mobile phone calls.
› Never drive when your driving ability is impaired, e.g. through medication, alco-
hol, drugs.
› Keep to the traffic regulations and the permissible speed limit.
› Always adjust the driving speed to the road, traffic and weather conditions.
› Take regular breaks on long journeys – at least every two hours. ÐCorrect seated position
ä
Introduction
This chapter contains information on the following subjects:
Correct seated position for the driver 76
Correct seated position for the front passenger 76
Correct seated position for the occupants on the rear seats 76
Examples of an incorrect seated position 76
WARNING
■ The front seats and rear head restraints must always be adjusted to match
the body size, in order to offer an optimal protection for you and your occu-
pants.
■ Always assume the correct seated position before setting off and do not
change this position while driving. Also advise your passengers to adopt the
correct seated position and not to change this position while the car is mov-
ing.
■ If the occupant adopts an incorrect seated position, he is exposed to life-
threatening injuries, in case he is hit by a deployed airbag.
ä WARNING (Continued)
■ If the occupants on the rear seats are not sitting upright, the risk of injury is
increased due to incorrect routing of the seat belt.
■ The driver must maintain a distance of at least 25 cm to the steering wheel.
The front passenger must maintain a distance of at least 25 cm to the dash
panel. Not maintaining this minimum distance will mean that the airbag sys-
tem 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 in
the 12 o'clock position or in any other way (e.g. in the middle or inner edge of
the steering wheel). In such cases, you could severely injure the arms, hands
and head when the driver airbag is deployed.
■ The seat backrests must not be angled too far back when driving otherwise
this will affect proper operation of the seat belts and of the airbag system –
risk of injury!
■ Ensure that there are no objects in the driver's footwell as they may get
caught behind the pedals when driving or applying the braking. You would
then no longer be able to operate the clutch, brake or accelerate.
■ Always keep your feet in the footwell when the car is being driven – never
place your feet on the instrument panel, out of the window or on the surfaces
of the seats. You will be exposed to increased risk of injury if it becomes nec-
essary to apply the brake or in the event of an accident. If an airbag is de-
ployed, you may suffer fatal injuries when adopting an incorrect seated posi-
tion! Ð

First read and observe the introductory information and safety warn-
ings on page 75.
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.
› Position the front passenger seat back as far as possible. The front passenger
must maintain a distance of at least 25 cm to the dash panel so that the airbag
offers the greatest possible safety if it is deployed.
› Correctly fasten the seat belt

First read and observe the introductory information and safety warn-
ings on page 75.
To reduce the risk of injury in the event of a sudden braking manoeuvre or an ac-
cident, the occupants on the rear seats must observe the following.
› 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.
› Correctly fasten the seat belt
» page 80.
› Use a suitable child restraint system if transporting children in the vehi-
cle
» page 87, Transporting children safely .Ð Examples of an incorrect seated position
First read and observe the introductory information and safety warn-
ings on page 75.
Seat belts offer their optimum protection only if the webbing of the seat belts is
properly routed. Incorrect seated positions considerably reduce the protective
functions of the seat belts and therefore increase the risk of injury due to an in-
correct routing of the seat belt. The driver is fully responsible for himself and pas-
sengers, especially children. Never allow a passenger to adopt an incorrect seated
position when the car is moving.
The following list contains examples of which seated positions can cause serious
injuries or death. This list is not complete, however we would like you to familiar-
ise yourself with this subject.
Therefore, while the car is moving never:
› stand up in the vehicle;
› stand up on the seats;
› kneel on the seats;
› tilt the seat backrest fully to the back;
› lean against the dash panel;
› lie on the rear seat bench;
› only sit on the front area of the seat;
› sit to the side;
› lean out of the window;

Introduction Fig. 79
Driver wearing seat belt
This chapter contains information on the following subjects:
The physical principle of a frontal collision 79
Fastening and unfastening seat belts 80
Belt tensioners 80
Seat belts that are fastened correctly offer good protection in the event of an ac-
cident. They reduce the risk of an injury and increase the chance of survival in the
event of a major accident.
Correctly fastened seat belts hold occupants of the car in the correct seated posi-
tion » Fig. 80 on page 79.
The seat belts reduce the kinetic energy (energy of motion) to a considerable ex-
tent. They also prevent uncontrolled movements which, in turn, may well result in
severe injuries.
The occupants of a vehicle who have fastened and correctly adjusted their seat
belt, profit to a major extent from the fact that the kinetic energy is optimally ab-
sorbed by the belts. The structure of the front end of the vehicle and other pas-
sive safety measures, such as the airbag system, also contribute to reducing the
kinetic energy. The energy produced is thus absorbed and there is less risk of in-
jury.
Particular safety aspects must be observed when transporting children in the ve-
hicle » page 87, Transporting children safely . WARNING
■ Fasten your seat belt before each journey – even when driving in town! This
also applies to the people seated at the rear – risk of injury!
■ Expectant women must also always wear a seat belt. This is the only way of
ensuring optimal protection for the unborn child » page 80.
■ Always ensure that the webbing of the seat belts is properly routed. Seat
belts which are not correctly adjusted can themselves cause injuries even in
minor accidents. ■ The maximum protection which seat belts can offer is only achieved if you
are correctly seated » page 75, Correct seated position .
■ The seat backrests of the front seats must not be tilted too far to the rear
otherwise the seatbelts can lose their effectiveness.
■ The belt webbing must not be jammed in-between at any point or twisted,
or chafe against any sharp edges.
■ A seat belt which is hanging too loose can result in injuries as your body is
moved forward by the kinetic energy produced in an accident and is then sud-
denly held firm by the belt.
■ The belt webbing must not run across solid or fragile objects (e.g. specta-
cles, ball-point pens, keys etc.) as this may be a cause of injuries.
■ No two persons (also not children) should ever use a single seat belt togeth-
er.
■ The lock tongue should only be inserted into the lock which is the correct
one for your seat. Wrong use of the safety belt will reduce its capacity to pro-
tect and the risk of injury increases.
■ The slot of the belt tongue must not be blocked by paper or similar objects
otherwise the belt tongue will not lock in place properly.
■ Many layers of clothing and loose clothing (e. g. a winter coat over a jacket)
do not allow you to be correctly seated and impairs proper operation of the
seat belts. ■ It is prohibited to use clamps or other objects to adjust seat belts (e. g. for
shortening the belts for smaller persons).
■ The seat belts for the rear seats can only fulfil their function reliably when
the seat backrests are correctly locked into position » page 40, Folding the
rear seat backrest forwards. ■ The belt webbing must always be kept clean. Soiled belt webbing may im-
pair proper operation of the inertia reel » page 103, Seat belts.
■ The seat belts must not be removed or changed in any way. Do not attempt
to repair the seat belts yourself. £
78 Safety

WARNING (Continued)
■ Check the condition of all the seat belts on a regular basis. If any damage to
the seat belts, seat belt connections, inertia reel or the lock is detected, the
relevant seat belt must be replaced by a specialist garage.
■ Damaged seat belts which have been subjected to stress in an accident and
were therefore stretched, must be replaced – this is best done by a specialist
garage. The anchorage points of the belts must also be inspected. The an-
chorage points for the belts should also be checked. Note
The national legal requirements must be observed when using seat belts. ÐThe physical principle of a frontal collision
Fig. 80
Driver without a fastened seat belt/rear seat passenger without a
fastened seat belt
First read and observe the introductory information and safety warn-
ings on page 78.
The physical principle of a frontal collision can be explained quite simply.
As soon as the vehicle is moving, so-called kinetic energy (the energy of motion)
is produced both in terms of the car as well as in terms of the 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 including 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. ä 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 of 30 km/h to 50 km/h, the forces that your body
is exposed to in the event of an accident can exceed a 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 or windscreen » Fig. 80 – . In certain circum-
stances you could even be thrown out of the vehicle, which could cause life
threatening or even 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 uncontrolled manner in the event
of an accident A rear seat passenger who has not fastened the seat belt is a dan-
ger not only to himself but also for those seated at the front » Fig. 80 – . Ð
