It is also possible under certain special accident situations that the front as well as
the side airbags and head airbags are deployed simultaneously.
The airbags
are not deployed in the case of minor frontal and side collisions, rear-
end collisions, tilting of the vehicle, and vehicle rollover.
Deployment factors
It is not possible to state globally which deployment conditions apply to the airbag
system in every situation as the circumstances which exist in the case of acci-
dents vary greatly. An important role in this case, for example, is played by factors
such as the type of object against which the vehicle impacts (hard, soft), the angle
of impact, the vehicle speed etc.
A decisive factor for the deployment of the airbags is the deceleration which oc-
curs during a collision. The control unit analyses the nature of the collision and ac-
tivates the relevant restraint system. If the vehicle deceleration which occurs and
is measured during the collision remains below the prescribed reference values
specified in the control unit, the airbags are not deployed although the vehicle
may well suffer severe damage to the bodywork as a consequence of the acci-
dent.
The airbags are not deployed if:
● ignition is switched off;
● a minor frontal collision;
● a minor side collision;
● a rear-end collision;
● Rollover of the vehicle. Note
● A grey white or red, non-harmful gas is released when the airbag is inflated.
This is perfectly normal and is not an indication of a fire in the vehicle.
● In the event of an accident in which the airbags are deployed:
– the interior lighting comes on (if the switch for the interior light is in the
door contact position),
– the hazard warning light is switched on;
– all the doors are unlocked;
– the fuel supply to the engine is interrupted. Front airbags
Description of the front airbags The airbag system is not a substitute for the seat belt!
Fig. 102 Driver airbag in the steering wheel/front passenger airbag in the dash panel
The front airbag for the driver is housed in the steering wheel
⇒ fig. 102
- left. The
front airbag for the front passenger is housed in the dash panel above the storage
compartment ⇒ fig. 102 - right. The installation positions are each marked with the
“AIRBAG” logo.
The front airbag system, in combination with three-point safety belts, offers addi-
tional protection for the head and chest area of the driver and front passenger in
the event of a frontal collision of major severity ⇒ in Important safety informa-
tion regarding the front airbag system on page 115.
The airbag is not a substitute for the seat belt, but is part of the complete passive
vehicle safety concept.
Please note that an airbag can only offer you optimal pro-
tection in combination with a seat belt which is fastened .
Apart from their normal protective function, a further task of the seat belts is to
also hold the driver and front passenger in a correct seated position in the event
of a frontal collision so as to enable the front airbags to offer the maximum pro-
tection.
You should therefore always fasten the seat belts, not only because this is re-
quired by law, but also for safety reasons and for your own protection ⇒ page 109,

Airbag system
WARNING
● The battery acid is strongly corrosive and must, therefore, be handled with
the greatest of care. Always wear protective gloves, eye and skin protection
when handling batteries. Corrosive fumes in the air irritate the air passages
and lead to conjunctivitis and inflammation of the air passages in the lungs.
Battery acid corrodes dental enamel and creates deep wounds after contact
with the skin which take a long time to heal. Repeated contact with diluted
acids causes skin diseases (inflammations, ulcers, slin cracks). Acids coming in-
to contact with water are diluted accompanied by significant development of
heat.
● Do not tilt the battery otherwise battery electrolyte may flow out of the
battery vent openings. Protect the eyes with safety glasses or a shield! There
is the danger of suffering blindness! If any battery electrolyte gets into your
eye, rinse out your eye immediately with clear water for several minutes. Con-
tact a doctor without delay.
● Splashes of acid on your skin or clothes should be neutralised as soon as
possible using soap suds and then rinsed with plenty of water. If acid was
swallowed, seek immediate medical attention.
● Keep batteries out of the reach of children.
● Hydrogen is released when you charge a battery and a highly explosive gas
mixture is produced. An explosion can be caused through sparkling over dur-
ing unclamping or loosening of the cable plug while the ignition is on.
● Bridging of the poles will create a short circuit (e.g. through metal objects,
cables). Possible consequences of a short circuit: Melting of lead struts, explo-
sion and burning of the battery, jets of acid spurting out.
● It is prohibited to work with a naked flame and light, to smoke or to carry
out any activities which produce sparks. Avoid creating sparks when working
with cables and electrical devices. Strong sparking represents a risk of injury.
● Before carrying out any work on the electrical system, switch off the en-
gine, the ignition as well as all electrical components and disconnect the neg-
ative cable (-) on the battery. If you wish to replace a bulb it is sufficient to
switch off the appropriate light.
● Never charge a frozen or thawed battery - risk of explosion and caustic
burns! Replace a frozen battery.
● Never jump-start the batteries which have a too low electrolyte level - risk
of explosion and caustic burns!
● Never use a battery which is damaged - risk of explosion! Immediately re-
place a damaged battery. CAUTION
● You must only disconnect the battery if the ignition is switched off, otherwise
the electrical system (electronic components) of the vehicle may be damaged.
When disconnecting the battery from the electrical system of the vehicle, first dis-
connect the negative terminal (-) of the battery. Then disconnect the positive ter-
minal (+).
● When reconnecting the battery, first connect the positive terminal (+) and only
then the negative terminal (-) of the battery. You must on no account connect the
cables wrongly - risk of a cable fire.
● Ensure that battery acid does not come into contact with the vehicle body oth-
erwise damage could occur to the paintwork.
● Do not place the battery in direct daylight in order to protect the battery hous-
ing from the effects of ultra-violet light.
● If the vehicle has not been driven for more than 3 to 4 weeks, the battery will
discharge This is because certain electrical components consume electricity (e. g.
control units) also in idle state. You can prevent the discharging of the battery by
disconnecting the negative terminal or charging the battery constantly with a very
low charging current. For the sake of the environment
A removed battery is a special type of waste which is harmful to the environment
- contact your specialist garage regarding disposing of the battery. Note
● Please also refer to the guidelines ⇒ page 162, also after connecting the bat-
tery.
● You should replace batteries older than 5
years.160
