airbag
Control lamp for disabled/enabled status
of the front passenger 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
››
page 23,
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 pro-
vide maximum protection if the occupants
are seat
ed correctly

If a fault has occurred in the airbag sys-
tem, 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
thousands of a second, t
o pr
o
vide additional
pr
ot
ection in the event of an accident. A fine
dust may develop when the airbag deploys.
This is normal and it is not an indication 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
Knee airbag for the driver.
The following airbags are triggered in seri-
ous side-on collisions:
Front side airbag on the side of the acci-
dent.
Curtain (head) airbag on the side of the ac-
cident.
