dash panel, out the window or on the seat. An
incorr
ect
sitting position exposes you to an
increased risk of injury in case of a sudden
braking or an accident. If the airbag is trig-
gered, you could sustain severe injuries due
to an incorrect sitting position.
● To reduce the risk of injury to the front pas-
senger in ev
ents such as sudden braking ma-
noeuvres or an accident, never travel with the
backrest tilted far back! The airbag system
and seat belts can only provide optimal pro-
tection when the backrest is in an upright po-
sition and the front passenger is wearing his
or her seat belt properly. The further the seat
backrests are tilted to the rear, the greater
the risk of injury due to incorrect positioning
of the belt web or to the incorrect sitting po-
sition!
● Adjust the head restraint correctly in order
to achiev
e maximum protection. Correct sitting position for rear seat

● If the p a

ssengers in the rear seats are not
sitting properly, they could sustain severe in-
juries.
● Adjust the head restraint correctly in order
to achiev
e maximum protection.
● Seat belts can only provide optimal protec-
tion when seat b
ackrests are in an upright
position and the vehicle occupants are wear-
ing their seat belts correctly. If passengers In
the rear seats are not sitting in an upright po-

tion
s Seat belts can provide optimal protection on-
ly
when the belt
w

ebs are properly posi-
tioned. Incorrect sitting positions substan-
tially reduce the protective function of seat
belts and increase the risk of injury due to in-
correct seat belt position. As the driver, you
are responsible for all passengers, especially
children. –

Drivers with properly worn seat belts
w i
l
l not be thrown forward in the event of sud-
den braking Properly worn seat belts hold the occupants
in the pr
oper po
s

ition. They also help prevent
uncontrolled movements that may result in
serious injury and reduce the risk of being
thrown out of the vehicle in case of an acci-
dent.
Vehicle occupants wearing their seat belts
correctly benefit greatly from the ability of the
belts to absorb kinetic energy. In addition,
the front part of your vehicle and other pas-
sive safety features (such as the airbag sys-
tem) are designed to absorb the kinetic ener-
gy released in a collision. Taken together, all
these features reduce the releasing kinetic
energy and consequently, the risk of injury.
This is why it is so important to fasten seat
belts before every trip, even when "just driv-
ing around the corner". Ensure that your passengers wear their seat
belts as

well. Accident statistics have shown
that wearing seat belts is an effective means
of substantially reducing the risk of injury
and improving the chances of survival when
involved in a serious accident. Furthermore,
properly worn seat belts improve the protec-
tion provided by airbags in the event of an
accident. For this reason, wearing a seat belt
is required by law in most countries.
Although your vehicle is equipped with air-
bags, the seat belts must be fastened and
worn. The front airbags, for example, are only
triggered in some cases of head-on collision.
The front airbags will not be triggered during
minor frontal or side collisions, rear-end colli-
sions, rollovers or accidents in which the air-
bag trigger threshold value in the control unit
is not exceeded.
Therefore, you should always wear your seat
belt and ensure that all vehicle occupants
have fastened their seat belts properly before
you drive off!
Safety instructions on using seat
belts –
Always wear the seat belt as described in
thi s
section.
– En

sure that the seat belts can be fastened
at all
times and are not damaged. WARNING
● If se at

belts are worn incorrectly or not at
all, the risk of severe injuries increases. The
optimal protection from seat belts can be
achieved only if you use them properly.
● Fasten your seat belt before every trip -
even when drivin
g in town. Other vehicle oc-
cupants must also wear the seat belts at all
times, otherwise they run the risk of being in-
jured.
● The seat belt cannot offer its full protection
if the seat
belt is not positioned correctly.
● Never allow two passengers (even children)
to shar
e the same seat belt.
● Always keep both feet in the footwell in
front of
your seat as long as the vehicle is in
motion.
● Never unbuckle a seat belt while the vehi-
cle i
s in motion. Risk of fatal injury.
● The seat belt must never be twisted while it
is bein
g worn.
● The seat belt should never lie on hard or
fragil
e objects (such as glasses or pens, etc.)
because this can cause injuries.
● Do not allow the seat belt to be damaged or
jammed, or to rub on an
y sharp edges.
● Never wear the seat belt under the arm or
in any other inc
orrect position.
● Loose, bulky clothing (such as an overcoat
over a j
acket) impairs the proper fit and func-
tion of the seat belts, reducing their capacity
to protect. » 73

Safety
The seat belts are equipped with an automat-
ic r
etr
actor 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 76.
Releasing the seat belt ● Press the red button on the belt buckle
›››
Fig. 92 B. The latch plate is released and
springs out ››› .
● Guide the belt back by hand so that it rolls
up e a
s

ily and the trim is not damaged.
Positioning seat belts
Seat belts offer their maximum protection on-
ly when they are properly positioned. WARNING
● The seat belt

s 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 u nb

uckle 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 injurie
s 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. 93.
● Always engage the retractor lock when you
are securin

 page 16.
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 belt tensioners will not be triggered in
the event of minor collisions, if the vehicle overturns, or in accidents where no major
forc

es act on the vehicle. Note
● If the se at

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
obser
ved 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 tension-
er
s The belt tensioners are components of the
se
at
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
do not cause any injuries or environmental
pollution, regulations, which are known to
the specialised workshops, must be ob-
served.

WARNING
● Improper u se or r
epairs not carried out by
qualified mechanics increase the risk of se-
vere or fatal injuries. The belt tensioners may
fail to trigger or may trigger in the wrong cir-
cumstances.
● Never attempt to repair, adjust, remove or
inst
all parts of the belt tensioners or seat
belts.
● The seat belt tensioner, seat belt and auto-
matic r
etractor cannot be repaired.
● Any work on the belt tensioners and seat
belts, includin
g the removal and refitting of
system parts in conjunction with other repair
work, must be performed by a specialised
workshop only.
● The belt tensioners will only provide pro-
tection for one ac
cident and must be changed
if they have been activated. Airbag system
Brief intr
oduction
Wh

y is it so important to wear a seat
belt and to sit correctly? For the inflating airbags to achieve the best
prot
ection, the se

at belt must always be worn
properly and the correct sitting position must
be assumed.
The airbag system is not a substitute for seat
belts, but it is an integral part of the vehicle's
overall passive safety system. Please bear in
mind that the airbag system can only work ef-
fectively when the vehicle occupants are
wearing their seat belts correctly and have
adjusted the head restraints properly. There-
fore, it is most important to properly wear the
seat belts at all times, not only because this
is required by law in most countries, but also
for your safety ›››
page 72, Why wear a seat
belt?.
The airbag inflates in a matter of seconds, so
if you are not properly seated when the air-
bag is triggered, you may sustain fatal inju-
ries. Therefore, it is essential that all vehicle
occupants assume a correct sitting position
while travelling.
Sharp braking before an accident may cause
a passenger not wearing a seat belt to be
thrown forward into the area of the deploying airbag. In this case, the inflating airbag may
inflict c
ritic

al or fatal injuries on the occu-
pant. This also applies to children.
Always maintain the greatest possible dis-
tance between yourself and the front airbag.
This way, the front airbags can completely
deploy when triggered, providing their maxi-
mum protection.
The most important factors that will trigger
an airbag are: the type of accident, the angle
of collision and the speed of the vehicle.
Whether or not the airbags are triggered de-
pends primarily on the vehicle deceleration
rate resulting from the collision and detected
by the control unit. If the vehicle deceleration
occurring during the collision and measured
by the control unit remains below the speci-
fied reference values, the front, side and/or
curtain airbags will not be triggered. Take in-
to account that the visible damage in a vehi-
cle involved in an accident, no matter how
serious, is not a determining factor for the
airbags to have been triggered. WARNING
● We arin

g the seat belt incorrectly or assum-
ing an incorrect sitting position can lead to
critical or fatal injuries.
● All vehicle occupants, including children,
who are not pr
operly belted can sustain criti-
cal or fatal injuries if the airbag is triggered.

● In a side-on collision the side airbags will
not work
if the sensors do not correctly meas-
ure the pressure increase on the interior of
the doors, due to air escaping through the
areas with holes or openings in the door pan-
el.
● Never drive if the interior door panels have
been remov
ed or if the panels have not been
correctly fitted.
● Never drive the vehicle if the loudspeakers
in the door panels
have been removed, un-
less the holes left by the loudspeakers have
been closed properly.
● Always check that the openings are closed
or cov
ered if loudspeakers or other equip-
ment are fitted inside the door panels.
● Occupants of the outer seats must never
carry
any objects or pets in the deployment
space between them and the airbags, or al-
low children or other passengers to travel in
this position. It is also important not to at-
tach any accessories (such as cup holders) to
the doors. This would impair the protection
offered by the side airbags.
● The built-in coat hooks should be used only
for lightweight
clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
● Great forces, such as hard blows or kicks,
must
not be exerted upon the backrest bol-
ster because the system may be damaged. In
this case, the side airbags would not be trig-
gered. ●
Under no cir c

umstances should protective
covers be fitted over seats with side airbags
unless the covers have been approved for use
in your vehicle. Because the airbag deploys
from the side of the backrest, the use of con-
ventional seat covers would obstruct the side
airbag, seriously reducing the airbag's effec-
tiveness.
● Any damage to the original seat upholstery
or around the se
ams of the side airbag units
must be repaired immediately by a special-
ised workshop.
● The airbags provide protection for just one
accident; r
eplace them once they have de-
ployed.
● Any work on the side airbag system or re-
mova
l and installation of the airbag compo-
nents for other repairs (such as removal of
the front seat) should only be performed by a
specialised workshop. Otherwise, faults may
occur during the airbag system operation.

ling.
● For safety reasons, the curtain airbag must
be disab
led in those vehicles fitted with a
screen dividing the interior of the vehicle.
See your technical service to make this ad-
justment.
● There must be no other persons, animals or
obj
ects 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.

● Any work on the head-protection airbag
syst
em 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.

Airbag system
●
The side and he a
d 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. Deactivating airbags
