gered in the event of the vehicle overturning
if the side airbags are not deployed.
If the belt tensioner is triggered, a fine dust is
produced. This is normal and it is not an indi-
cation of fire in the vehicle.
Belt tension limiter
The belt tension limiter reduces the force of
the seat belt on the body in the event of an
accident. Note
The relevant safety requirements must be ob-
serv ed when the

vehicle is dismantled or sys-
tem components are removed. These require-
ments are known to specialised workshops

dev
ice

s If you work on the belt tensioners or remove
and in
s
t

all other parts of the vehicle when
performing other repair work, the seat belt
may be damaged. The consequence may be
that, in the event of an accident, the belt ten-
sioners function incorrectly or not at all. So that the effectiveness of the belt tensioner
is not

reduced and that removed parts do not
cause any injuries or environmental pollu-
tion, regulations must be observed. These re-
quirements are known to specialised work-
shops. 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. For the sake of the environment
Airbag modules and belt tensioners may con-
tain per c

hlorate. Observe the legal require-
ments for their disposal. Airbag system
Brief intr
oduction
Intr

oduction Front airbags have been installed for both
driver and p
a

ssenger. The front airbags can
also protect the chest and head of driver and
passenger if the seats, seat belts head re-
straints and, for the driver, the steering
wheel are correctly adjusted and used. Air-
bags are considered as additional safety
equipment. An airbag cannot replace the
seat belt, which must be worn at all times,
even in front seats where front airbags have
been installed.
The airbag can protect vehicle occupants in
the event of an accidents, cushioning the
movement of the occupants in the direction
of the collision in frontal and side accidents.
Deployed airbags fill with a propellant gas.
This causes the airbag covers to break and
the airbags to deploy extremely quickly in
their entire deployment space within frac-
tions of a second. When an occupant with the
seat belt properly fastened puts pressure on
the inflated airbag, the propellant gas es-
capes to absorb the force of the impact and
slow the movement. This reduces the risk of
severe or fatal injuries. Airbag deployment
does not mean that other types of injury such

Airbag system
WARNING
● The seat belt
s and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 48.
● If a fault has occurred in the airbag system,
have the sy
stem checked immediately by a
specialised workshop. Otherwise, during a
frontal collision the system might not trigger
correctly or may fail to trigger at all. Airbag activation
The airbags deploy extremely rapidly, within
thou
s
andths

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,
such as the properties of the object the vehi- cle hits (hard/soft), angle of impact, vehicle
speed, etc

.
Deceleration trajectory is key for airbag acti-
vation.
The control unit analyses the collision trajec-
tory and activates the respective restraint
system.
If the deceleration rate is below the prede-
fined reference value in the control unit the
airbags will not be triggered, even though
the accident may cause extensive damage to
the car.
The following airbags are triggered in seri-
ous head-on collisions ● Driver airbag.
● Front passenger front airbag
The fol
lowing airbags are triggered in seri-
ous side-on collisions
● Front side airbag on the side of the acci-
dent.
● Re

ar side airbag on the side of the acci-
dent.
In an acc

ident with airbag activation:
● the interior lights switch on (if the interior
light swit
ch is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked; ●
the fuel s
upply to the engine is cut.

penetration of a foreign body of up to about
4 mm in diameter. Do not remove foreign ob-
jects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre,
you must again check the tyre pressure about
10 minutes after starting the engine.
You should only use the tyre mobility set if
the vehicle is parked in a safe place, you are
familiar with the procedure and you have the
necessary tyre mobility set! Otherwise, you
should seek professional assistance.
Do not use the tyre sealant in the following
cases:
● If the wheel rim has been damaged.
● In outside temperatures below -20°C (-4°F).
● In the event of cuts or perforations in the
tyre gr
eater than 4 mm.
● If you have been driving with very low pres-
sure or a c
ompletely flat tyre.
● If the sealant bottle has passed its use by
date. WARNING
Using the tyre mobility system can be dan-
ger ou

s, especially when filling the tyre at the
roadside. Please observe the following rules
to minimise the risk of injury: ●
Stop the v

ehicle safely as soon as possible.
Park it at a safe distance from surrounding
traffic to fill the tyre.
● Ensure the ground on which you park is flat

erwise, you should seek professional assis-
tance.
● The tyre mobility set is intended for tempo-
rary
emergency use only until you can reach
the nearest specialised workshop.
● Replace the repaired tyre with the tyre mo-
bility
set as soon as possible.
● The sealant is a health hazard and must be
cle
aned immediately if it comes into contact
with the skin.
● Always keep the tyre mobility set out of the
reac
h of small children.
● Never use an equivalent jack, even if it has
been appro
ved for your vehicle.
● Always stop the engine, apply the hand-
brake l
ever firmly and engage gear if using a
manual gearbox, in order to reduce the risk of
vehicle involuntary movement. WARNING
A tyre filled with sealant does not have the
same per f

ormance properties as a conven-
tional tyre.
● Never drive faster than 80 km/h (50 mph).
● Avoid heavy acceleration, hard braking and
fas
t cornering.
● Drive for only 10 minutes at a maximum
speed of 80
