Safety
Pretensioners
The seat belts are fitted with pyrotechnic-powered pretensioners.
The pretensioner is activated by the airbag ECU where there is:
- a sufficiently severe head-on collision (direction of impact
between 11 and 1 o'clock p.m.);
- a sufficiently severe side collision;
- a side roll-over.
The belt will rewind a few centimetres just before the restraining
action begins, thereby improving the fitting across the occupant's
body.
Activation of a pretensioner is signalled by the illumination of the
warning light A on the instrument panel.
Warning
If there is a side collision, only the pretensioner on the side
where the collision occurs will be activated.
Warning
Pretensioners that have been activated will no longer function
and may not be repaired under any circumstances. Contact the
Ferrari Service Network for replacement.
When a pretensioner is activated, a small amount of smoke is
released. This smoke is not harmful.
Warning
Activation of the pretensioners only depends on the status of the
seat belts and is not affected by the occupants' presence.
If the seat belt is not fastened, the pretensioner will not activate,
even if the seat is occupied.
The seat belts are fitted with a load limiting device. The load
limiting device is located in the belt retractor and allows controlled
release of the belt during a collision thereby limiting the impact
that the belt has on the occupant's body.
