Warning
Do not let the seat belts come into contact with cutting edges.
They may get damaged and may consequently break in the
event of a collision.
Warning
Each seat belt has been designed to protect only one occupant.
If more than one person uses the same seat belt, the risk of
injury in the event of an accident is increased.
The seat belt must never be passed around a baby, child or
other person sitting on a passenger's lap.
Do not sit babies, small children or other persons on your lap.
If there is a collision, the weight of an adult may cause the
child to be crushed by the seat belt causing severe or even fatal
injuries.
Warning
Do not attach or pin anything onto the seat belts: they may get
damaged and may consequently break in the event of a collision.
Warning
If a seat belt has come into contact with cutting edges or was
somehow perforated, we recommend that you have it replaced
by the Ferrari Service Network.
Warning
Periodically check the condition of the seat belts. If the belt
shows signs of wear, it must be checked by a qualified person
and replaced if necessary. Contact the Ferrari Service
Network immediately.
