The reasons why we should
wear seat belts Number of seats Your vehicle has
five seats, two in the front
and thr ee in the r
ear. Each seat is equipped
with a three-point seat belt.
In some versions, your vehicle is approved
only for four seats. Two front seats and two
r e

ar seats. WARNING
● Never transport more than the permitted
amount of people in your vehicle.
● Every vehicle occupant must properly fas-
ten and wear the seat belt belonging to his or
her seat. Children must be protected with an
appropriate child restraint system. Seat belt warning lamp*

driver to fasten his seat belt.
Before starting the vehicle:
– Fasten your seat belt securely.
– Instruct your passengers to fasten their
seat belts properly before driving off.
– Protect children by using a child seat ac-
cording to the child's height and weight.
When the ignition is switched on, the control
lamp  in the instrument panel lights up (de-
pending on the model version) if the driver or
passenger have not fastened their seat belts.
An audible warning signal will sound for a
few seconds if the seat belts are not fastened
as the vehicle drives off and reaches a speed of more than approximately 25 km/h
(15 mph) or if the seat belts are unfastened
while the vehicle is in motion. The warning

Seat belts
●
The slot in the seat belt buckle must not be
blocked with paper or other objects, as this
can prevent the latch plate from engaging se-
curely.
● Never use seat belt clips, fastening rings or
similar items to alter the position of the belt
webbing.
● Frayed or torn seat belts or damage to the
connections, belt retractors or parts of the
buckle could cause severe injuries in the
event of an accident. Therefore, you must
check the condition of all seat belts at regular
intervals.
● Seat belts which have been worn in an acci-
dent and stretched must be replaced by a
specialised workshop. Renewal may be nec-
essary even if there is no apparent damage.
The belt anchorage should also be checked.
● Do not attempt to repair a damaged seat
belt yourself. The seat belts must not be re-
moved or modified in any way.
● The belts must be kept clean, otherwise the
retractors may not work properly. Head-on collisions and the laws of
physics
Fig. 62
A driver not wearing a seat belt is
thrown forward violently Fig. 63
The unbelted passenger in the rear
seat is thrown forward violently, hitting the
driver who is wearing a seat belt. It is easy to explain how the laws of physics
work in the case of a head-on collision: when
a vehicle starts moving, a type of energycalled “kinetic energy” is created both in the
passengers and inside the vehicle.
The amount of “kinetic energy” depends on
the speed of the vehicle and the weight of
the vehicle and its passengers. The higher
they are, the more energy there is to be “ab-
sorbed” in the event of an accident.
The most significant factor, however, is the
speed of the vehicle. If the speed doubles
from 25 km/h (15 mph) to 50 km/h
(30 mph), for example, the corresponding ki-
netic energy is multiplied by four.
Given that the passengers of the vehicle in
our example do not have their seat belts fas-
tened, in the event of a collision the entire
amount of the passengers' kinetic energy will
be only absorbed by the mentioned impact.
Even at speeds of 30 km/h (19 mph) to
50 km/h (30 mph), the forces acting on bod-
ies in a collision can easily exceed one tonne
(1000 kg). At greater speed these forces are
even higher.
Vehicle occupants not wearing seat belts are
not “attached” to the vehicle. In a head-on
collision, they will move forward at the same
speed their vehicle was travelling just before
the impact. This example applies not only to
head-on collisions, but to all accidents and
collisions.
Even at low speeds the forces acting on the
body in a collision are so great that it is not

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

● 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.

sioner is not reduced and that removed parts

children in the vehicle if they are not restrain-
ed or the restraint system is not appropriate
for their age, size or weight.
●
If you are not wearing a seat belt, or if you
lean forward or to the side while travelling or
assume an incorrect sitting position, there is
a substantially increased risk of injury. This
increased risk of injury will be further in-
creased if you are struck by an inflating air-
bag.
● To reduce the risk of injury from an inflating
airbag, always wear the seat belt properly
››› page 43.
● Alw
ays adjust the front seats properly. Description of airbag system
The airbag system is not a substitute for the
seat belts. The airbag system offers addition-
al protection for the driver and passenger in
combination with the seat belts.
The airbag system comprises the following
modules (as per vehicle equipment):
●
Electronic control unit
● Front airbags for driver and passenger
● Knee airbag for the driver
● Side airbags
● Head airbag ●
Airbag control lamp  on the instrument
panel
● Key-operated switch for front passenger air-
bag
● Control lamp to disconnect/connect the
front airbag.
The airbag system operation is monitored
electronically. The airbag control lamp will il-
luminate for a few seconds every time the ig-
nition is switched on (self-diagnosis).
There is a fault in the system if the control
lamp :
● does not light up when the ignition is
switched on,
● turns off after 4 seconds after the ignition
is switched on
● turns off and then lights up again after the
ignition is switched on
● illuminates or flashes while the vehicle is
moving.
The airbag system is not triggered if:
● the ignition is switched off
● there is a minor frontal collision
● there is a minor side collision
● there is a rear-end collision
● the vehicle turns over. WARNING
● The seat belts and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 38, Sitting position
for vehicle occupants .
● If a fault has occurred in the airbag system,
have the system checked immediately by a
specialised workshop. Otherwise there is a
danger that during a collision, the system
may fail to trigger, or not trigger correctly. Airbag activation
The airbags deploy extremely rapidly, within
thousandths of a second, to provide addi-
tional protection in the event of an accident.
A fine dust may develop when the airbag de-
ploys. This is normal and it is not an indica-
tion of fire in the vehicle.
The airbag system is only ready to function
when the ignition is on.
In special accidents instances, several air-
bags may activate at the same time.
In the event of minor head-on and side colli-
sions, rear-end collisions, overturning or roll-
over of the vehicle, airbags
do not activate.
Activation factors
The conditions that lead to the airbag system
activating in each situation cannot be gener-
alised. Some factors play an important role, »

rem
ain connected to the steering wheel or
the dash panel. In conjunction with the seat belts, the front
airbag system gives the front occupants ad-
ditional protection for the head and chest in
the event of a severe frontal collision
››› .
The special design of the airbag allows the
controlled escape of the propellant gas when
an occupant puts pressure on the bag. Thus,
the head and chest are surrounded and pro-
tected by the airbag. After the collision, the
airbag deflates sufficiently to allow visibility. WARNING
● The deployment space between the front
passengers and the airbags must not in any
case be occupied by other passenger, pets
and objects.
● The airbags provide protection for just one
accident; replace them once they have de-
ployed.
● It is also important not to attach any ob-
jects such as cup holders or telephone
mountings to the surfaces covering the air-
bag units.
● Do not attempt to modify components of
the airbag system in any way. Types of front passenger front airbag

WARNING
● If you do not wear a seat belt, if you lean
forward, or are not seated correctly while the
vehicle is in motion, you are at a greater risk
of injury if the side airbag system is triggered
in an accident.
● In order for the side airbags to provide their
maximum protection, the prescribed sitting
position must always be maintained with
seat belts fastened while travelling.
● 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 removed 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 covered 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 circumstances 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 seams of the side airbag units
must be repaired immediately by a special-
ised workshop.
● The airbags provide protection for just one
accident; replace them once they have de-
ployed.
● Any work on the side airbag system or re-
moval 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.
● Do not attempt to modify components of
the airbag system in any way. Head-protection airbags*

protection airbag system gives the vehicle
occupants additional protection for the head
and upper body in the event of a severe side
collision ››› .
WARNING
● In order for the head-protection airbags to
provide their maximum protection, the pre-
scribed sitting position must always be main-
tained with seat belts fastened while travel-
ling.
● For safety reasons, the curtain airbag must
be disabled in those vehicles fitted with a

The p a

ssenger side front airbag, when ena-
bled, is a serious risk for a child that is facing
backward since the airbag can strike the seat
with such force that it can cause serious or
fatal injuries. Children up to 12 years old
should always travel on the rear seat.
Therefore we strongly recommend you to
transport children on the rear seats. This is the safest location in the vehicle. Alternative-
ly, the front passenger airbag can be disa-
bled with a key-operated switch
››› page 55.
When transporting children, use a child seat
suitable for the age and size of each child
››› page 58. WARNING
● If a child seat is secured to the front pas-
senger seat, the risk to the child of sustain-
ing critical or fatal injuries in the event of an
accident increases.
● An inflating front passenger airbag can
strike the rear-facing child seat and project it
with great force against the door, the roof or
the backrest.
● Never install a child seat facing backwards
on the front passenger seat unless the front
passenger front airbag has been disabled.
Risk of potentially fatal injuries to the child!
However, if it is necessary, in exceptional ca-
ses, to transport a child in the front passen-
ger seat, the front passenger front airbag
must always be disabled ››› page 54. If the
passenger seat has a height adjustment op-
tion, move it to the highest, most upright po-
sition. If you have a fixed seat, do not install
any child restraint system in this location.
● For those vehicles that do not include a key
lock switch to deactivate the airbag, the vehi-
cle must be taken to a technical service.
● All vehicle occupants, especially children,
must assume the proper sitting position and
be properly belted in while travelling. » 57
