Seat belts
The seat belts are equipped with an automat-
ic retractor on the shoulder strap. Full free-
dom of movement is permitted when the
shoulder belt is pulled slowly. However, dur-
ing sudden braking, during travel in steep
areas or bends and during acceleration, the
automatic retractor on the shoulder belt is
locked.
The automatic belt retractors on the front
seats are fitted with seat belt tensioners
››› page 47 .
R el
easing the seat belt
● Press the red button on the belt buckle
››› Fig. 64 B
. The latch plate is released and
springs out ››› .
● Guide the belt back by hand so that it rolls
up easily and the trim is not damaged.
Adjusting the seat belt
Seat belts offer their maximum protection on-
ly when they are properly positioned
››› Fig. 65 . WARNING
● The seat belts offer best protection only
when the backrests are in an upright position
and the seat belts have been fastened prop-
erly.
● Never put the latch plate in the buckle of
another seat. If you do this, the seat belt will not protect you properly and the risk of injury
is increased.
●
Never unbuckle a seat belt while the vehi-
cle is in motion. If you do, you increase the
risk of sustaining severe or fatal injuries.
● An incorrectly worn seat belt can cause se-
vere injuries in the event of an accident.
● For pregnant women, the lap part of the
seat belt must lie as low as possible over the
pelvis, never across the stomach, and always
lie flat so that no pressure is exerted on the
abdomen ››› Fig. 65.
● Alw

ays engage the retractor lock when you
are securing a child seat in group 0, 0+ or 1
››› page 56.
● Re

ad and observe the warnings ››› page 44. Seat belt tensioners
How the seat belt tensioner works During a frontal collision, the seat belts on
the front seats are retracted automatically.
The seat belts for the occupants in the front
seats are equipped with belt tensioners. Sen-
sors will trigger the belt tensioners only dur-
ing severe head-on, lateral and rear-end colli-
sions and only if the seat belt is worn. This
retracts and tightens the seat belts, reducing
the forward motion of the occupants.The seat belt tensioner can be triggered only
once.
The seat belt tensioners will not be triggered
in the event of a light frontal, side or rear col-
lision, if the vehicle overturns or in situations
where no large forces act on the front, side or
rear of the vehicle.
Note
● If the seat belt tensioners are triggered, a
fine dust is produced. This is normal and it is
not an indication of fire in the vehicle.
● The relevant safety requirements must be
observed when the vehicle or components of
the system are scrapped. Specialised work-
shops are familiar with these regulations,
which are also available to you. Service and disposal of belt
tensioners
The belt tensioners are components of the
seat belts that are installed in the seats of
your vehicle. If you work on the belt tension-
ers or remove and install parts of the system
when performing other repair work, the seat
belt may be damaged. The consequence may
be that, in the event of an accident, the belt
tensioners function incorrectly or may not
function at all.
So that the effectiveness of the seat belt ten-
sioner is not reduced and that removed parts

●
There must be no other persons, animals or
objects between the occupants of the outer
seats and the deployment space of the head-
protection airbags so that the head-protec-
tion airbag can deploy completely without re-
striction and provide the greatest possible
protection. Therefore, sun blinds which have
not been expressly approved for use in your
vehicle may not be attached to the side win-
dows
● The built-in coat hooks should be used only
for lightweight clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
Please, do not hang the clothes on coat hang-
ers.
● The airbags provide protection for just one
accident; replace them once they have de-
ployed.
● Any work on the head-protection airbag
system or removal and installation of the air-
bag components for other repairs (such as re-
moval of the roof lining) should only be per-
formed by a specialised workshop. Other-
wise, faults may occur during the airbag sys-
tem operation.
● Do not attempt to modify components of
the airbag system in any way.
● The side and head airbags are managed
through sensors located in the interior of the
front doors. To ensure the correct operation of
the side and curtain airbags neither the
doors nor the door panels should be modified
in any way (e.g. fitting loudspeakers). If the front door is damaged, the airbag system
may not work correctly. All work carried out
on the front door must be done in a special-
ised workshop.
