Safety -> Pre-Tensioners for Your Fiat 500 C 2 Door Second Generation (2021-2025)

35)  
SBR SYSTEM (Seat  
Belt Reminder)  
PRE-TENSIONERS  
LOAD LIMITERS  
The car is equipped with front seat  
belts pretensioners, that reduce slack in  
the belts in the event of a severe frontal  
collision. This guarantees the perfect  
adherence of the seat belts to the  
occupants' bodies before the  
(for versions/markets, where provided)  
To increase occupant safety, the  
retractors of the safety belts contain a  
load limiter to dose the force acting  
on the chest and shoulders during the  
belt restraining action in the case of  
frontal collisions.  
The SBR system warns the passengers  
of the front and rear (for versions/  
markets, where provided) seats if their  
seat belt is not fastened.  
restraining action begins.  
The system warnings unfastened seat  
belts with visual warnings (warning  
lights on in the instrument panel and  
icons on the display) and an acoustic  
warning (see the following paragraphs).  
NOTE Contact a Fiat Dealership to  
deactivate this acoustic warning  
permanently. The acoustic warning can  
be reactivated at any time through the  
display Setup Menu.  
It is evident that the pretensioners have  
operated when the belt withdraws  
towards 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.  
The pretensioner does not require any  
maintenance or lubrication: any  
changes to its original conditions will  
invalidate its efficiency.  
GENERAL  
INSTRUCTIONS FOR  
USING THE SEAT BELTS  
88)  
Seat belts are also to be worn by  
pregnant women: the risk of injury in  
the case of impact is greatly reduced  
for them and the unborn child if they  
are wearing a seat belt.  
Pregnant women must position the  
lower part of the belt very low down so  
that it passes over the pelvis and under  
the abdomen (see fig. 55).  
While pregnancy increases, the driver  
must adjust both seat and steering  
wheel to have full control over the  
vehicle (pedals and steering wheel  
should be easily accessed).  
The maximum clearance should be  
kept between the abdomen and the  
steering wheel.  
Seat belts warning light operation  
The system warns the driver and the  
front passenger if their seat belt is  
not fastened, as follows:  
flashing warning light and  
intermittent acoustic warning for about  
100 seconds.  
If, due to unusual natural events (floods,  
sea storms, etc.), the device has been  
affected by water or mud, have it  
replaced.  
once the cycle has finished, the  
warning light remains on constantly until  
the seat belts are fastened.  
IMPORTANT To obtain the highest  
degree of protection from the action of  
the pretensioner, wear the seat belt  
tight to the chest and pelvis.  
85) 86) 87)

Each seat belt must be used by only  
one person. Never travel with a child  
sitting on the passenger's lap and  
a single belt to protect them both fig.  
57. In general, do not place any objects  
between the person and the belt.  
prevent the retractors from getting  
wet: their correct operation is only  
guaranteed if water does not get inside  
replace the seat belt when it shows  
wear or cuts.  
WARNING

55  
85) The pretensioner may be used only  
once. Contact a Fiat Dealership to have it  
replaced after it has been deployed.  
The seat belt strap must not be twisted.  
The upper part must pass over the  
shoulder and cross the chest  
diagonally. The lower part must adhere  
to the pelvis rather than the  
passengers abdomen (as shown in fig.  
56) . Never use devices (clips, clamps,  
etc.) that hold the seat belt away from  
your body.  
86) For maximum safety, keep the back of  
your seat upright, lean back into it and  
make sure the seat belt fits closely across  
your chest and pelvis. Always fasten the  
seat belts on both the front and the rear  
seats! Travelling without wearing seat belts  
will increase the risk of serious injury or  
even death in the event of an accident.

SEAT BELTS  
MAINTENANCE  
87) Removing or tampering with seat belt  
and pretensioner components is strictly  
prohibited. Any intervention on these  
components must be performed by  
qualified and authorised technicians.  
Always go to a Fiat Dealership.  
For keeping the seat belts in efficient  
conditions, carefully observe the  
following warnings:  
always use the seat belt with the  
strap well stretched and not twisted;  
make sure that it is free to run without  
obstructions;  
88) If the seat belt has been subjected to a  
high level of stress, for example after an  
accident, it must be completely replaced  
together with the anchorages, anchorage  
fixing screws and pretensioner. In fact,  
even if the seat belt has no visible defects,  
it could have lost its resilience.  
check seat belt operation as follows:  
attach the seat belt and pull it hard;  
replace the seat belt after an  
accident of a certain severity even if it  
does not appear to be damaged.  
Always replace the seat belt if
