Description of the airbag system
The airbag system offers additional protec-
tion for the occupants in combination with the
seat belts.
The airbag system comprises the follow-
ing modules (as per vehicle equipment):
Electronic control unit
●
Front airbags for driver and passenger
●
Knee airbag for the driver
●
Side airbags
●
Central airbag for the driver
●
Head 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

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
●
WARNING
The seat belts and airbags can only pro-

vide maximum protection if the occupants
on the instrument
are seated 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, to provide additional
protection 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.
Airbags do not activate in the event of minor
head-on and side collisions or rear-end colli-
sions. Airbags only activate if the vehicle
overturns in the hybrid plug-in version of the
vehicle.
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.
