Seat belts that are fastened correctly offer good protection in the event of an
accident. 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
position » Fig. 3.
The seat belts reduce the kinetic energy (energy of motion) to a considerable
extent. They also prevent uncontrolled movements which, in turn, may well re-
sult in severe injuries.
Occupants of a vehicle who have correctly fastened their seat belts have the
major benefit of the fact that the kinetic energy is absorbed as effectively as
possible by the belts.
The structure of the front end of the vehicle and other passive safety meas-
ures, such as the airbag system, also contribute to the kinetic energy being re-
duced as effectively as possible. The energy produced is thus absorbed and
there is less risk of injury.
Particular safety aspects must be observed when transporting children in the
vehicle » page 23 .
WARNING■
Fasten your seat belt before each journey - even when driving in town!
This also applies to the passengers 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 14, Fastening
and unfastening seat belts .
■
Maximum seat belt protection is only achieved if you are correctly seat-
ed » page 9 .
■
The seat backrests of the front seats must not be tilted too far to the rear
otherwise the seatbelts can lose their effectiveness.
WARNINGInformation on the correct routing of the belt■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.■
Adjust the height of the belt in such a way that the shoulder part of the
belt is roughly positioned across the middle of your shoulder - on no ac-
count across your neck.
■
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
suddenly held firm by the belt.
■
The belt webbing must not run across solid or fragile objects (e.g. specta-
cles, ball-point pens, bunches of keys etc.). Such objects can cause injury.
WARNINGInformation on dealing with the safety belts■The belt webbing must not be jammed in-between at any point or twis-
ted, or chafe against any sharp edges.■
Make sure you do not catch the seat belt in the door when closing it.
WARNINGInformation on the proper use of safety belts■Never use one seat belt to secure two persons (including children). The
seatbelt must not be placed over a child who is sitting on the lap of another
passenger. 12Safety
Belt height adjustment on the front seatsFig. 7
Front seat: Seat belt height ad-
juster
Read and observe on page 12 first.
The seat belt height adjuster makes it possible to adjust the routing of the
front seat belts in the area of the shoulder to the body size.
›
Press the seat belt height adjuster and move up or down in the desired di-
rection » Fig. 7.
›
Then pull firmly on the belt to ensure that the seat belt height adjuster has
correctly locked in place.
Seat belt for the rear middle seat
Read and observe
on page 12 first.
The seat belt for the rear middle seat is anchored in the area of the boot on
the left side of the headliner.
Fasten
›
Pull the belt with both lock tongues out of the headliner mount.
›
Insert the lock tongue at the end of the belt into the belt buckle on the left
side until it is heard to lock in place.
›
Pull the second lock tongue, which is moveable on the seat belt, over the
chest and insert it into the belt buckle on the right side until it is heard to
lock in place.
›
Pull on the seat belt to check that both lock tongues are securely engaged in
the locks.
The belt tongues for the rear middle seat are shaped differently so that they
only fit into the correct belt buckle. If you are not able to insert a lock tongue
into the wrong belt lock you probably tried to put it into the wrong buckle.
Release›Take off the safety belt in the reverse order to how you fasten it.›
Guide the belt back by hand so that the webbing rolls up easily, the seat belt
is not twisted and the trim panel is not damaged.
WARNING■ After releasing the seat belt hold it tight and let it slowly reel up until
both lock tongues lock into the headliner mount and are secured with a
magnet - there is a risk of injury.■
Never unlock both lock tongues simultaneously.
Inertia reels and belt tensioners
Introduction
This chapter contains information on the following subjects:
Intertia reel

Belt tensioners
15
Intertia reel
Each seat belt is equipped with an inertia reel.
When pulling slowly on the seat belt, the belt can move freely. When pulling
sharply on the seat belt, the movement is locked by the inertia reel.
The belts also lock when full braking, when the car accelerates, when driving
downhill and when cornering.
WARNINGIf the seat belt does not lock when pulling sharply on it, have it inspected
immediately by a specialist garage.
Belt tensioners
Safety for the driver and front passenger wearing their seat belts is enhanced
by the belt tensioners fitted to the inertia reels of the front three-point seat
belts.
The three-point seat belts are automatically tensioned in the event of a frontal
collision of a certain severity. The belt tensioners can also be deployed if the
seat belts are not fastened.

Note■After a certain time, play can develop within the adjustment mechanism of
the backrest angle.■
For safety reasons, it is not possible to store the seat position in the electric
seat memory and remote control key memory if the inclination angle of the
seat backrest is more than 102° in relation to the seat cushion.
■
Each time you store the position of the electrically adjustable driver's seat
and exterior mirrors, the existing setting is deleted.
