Sbr System (Seat Belt Reminder); Pretensioners - Alfa Romeo 4C Owner's Handbook Manual

SBR (Seat Belt Reminder)
SYSTEM
This system comprises an acoustic
warning which, in conjunction with the
warning light flashing on the instrument
panel, advises the driver if their seat belt
has not been fastened.
Contact a dedicated Alfa Romeo
Dealership to deactivate this acoustic
warning permanently.
The acoustic warning can be reactivated
at any time through the Setup menu (see
"Menu items" paragraph in "Knowing the
instrument panel" chapter).
If the driver side seat belt is not
fastened, when 20 km/h is exceeded or
when travelling at a speed from 10 to
20 km/h for longer than 5 seconds, an
acoustic signal sequence will be started
(continuous acoustic signal for the first 6
seconds followed by approximately
90 seconds of intermittent beeping) and
<
the warning light will flash.
At the end of the cycle, the warning lights
stay on with a fixed light until the car is
turned off. The acoustic signal is
interrupted immediately when the seat
<
belt is fastened.
If the seat belt is unfastened again when
driving the car, the acoustic signal and
the flashing warning light resume as
described previously.
PRE-TENSIONERS
The car is equipped with seat belt
pretensioners, which draw back the seat
belts by several centimetres in the event
of a strong frontal impact. This
guarantees the perfect adherence of the
seat belts to the occupant's bodies
before the retention action begins.
It is evident that the pretensioners have
operated when the belt withdraws
toward the retractor.
This car is also equipped with a second
pretensioner (fitted in the kick plate
area). Its activation is signalled by the
shortening of the metal cable.
A slight discharge of smoke may be
produced during the activation of the
pretensioner which is not harmful and
does not involve any fire hazard.
IMPORTANT To obtain the highest
degree of protection from the action of
the pretensioning device, wear the seat
belt, keeping it close to the chest and
pelvis.
