FRONT AIRBAGS (fig. 85)
Description and operation
The front airbag (driver and pas-
senger) is a safety device which is im-
mediately triggered in the event of a
front impact.
It consists of an instantly inflatable
bag housed in a special compartment
located:
– in the centre of the steering wheel
on the driver’s side;
– in the dashboard on the passen-
ger’s side (larger bag).
The front airbag (driver and pas-
senger) is a device which protects the
occupants of the car during a head-on
collision of a medium-high degree.
The system was designed to protect
from injury caused by the body crash-
ing to the steering wheel or the dash-
board. IMPORTANTCars fitted with ABS
must always be fitted with the wheel
rims, tyres and brake linings of the
type and make recommended by the
Manufacturer.
The system also includes the EBD
electronic brake correction (Electronic
Brake Distributor) which, through the
control unit and the ABSsensors fur-
ther enhances the braking system.
The car is fitted with an
electronic brake distribu-
tor (EBD). If warning lights
>andxlight up simultaneously
when the engine is running, this
indicates an EBD fault. This
means that violent braking could
cause early locking of the rear
wheels causing the car to skid.
Drive very carefully to the nearest
LANCIA Dealership to have the
system checked.
If only warning light >
switches on when the en-
gine is running, this usu-
ally indicates an ABS fault. In such
cases the braking system is still ef-
ficient, although the anti-locking
device does not function. The EBD
system may also be less efficient.
Go to a LANCIA Dealership imme-
diately, taking care not to brake
suddenly, and have the system
checked.
If the xbrake fluid low
warning light comes on,
stop the car immediately
and contact the nearest LANCIA
Dealership. Fluid leaks from the
hydraulic system, can compromise
brake system operation, both tra-
ditional systems and systems with
ABS.
