Maserati Gransport Owner's Manual page 24

The pretensioners do not require
maintenance or lubrication.
Tampering with the devices will
compromise their efficient operation.
If, as a result of exceptional natural
circumstances (floods, heavy seas, etc.),
the device has been in contact with
water and or sludge, it is absolutely
2
essential to replace it.
To ensure the best protection from the
pretensioners, secure the belt snugly
across your chest and pelvis.
The pretensioners will
operate only once, and will
operate even if the belts are
not fastened. Therefore, they must be
replaced by your Authorized Maserati
Dealer after they are activated. The
units have a ten year service life from
the date of manufacture; they must
be replaced when their service life is
near expiration.
24 Seat belts
WARNING: Work on the vehicle which
involves blows, vibrations or localized
heating (over 212 °F - 100 ˚C for 6
hours) in the area of the pretensioners
may damage or activate them:
vibrations due to bad road surfaces or
mounting the pavement, for instance,
should not affect the units. Please
contact your Authorized Maserati
Dealer if service must be carried out.
Do not tamper with the
pretensioner components.
Any intervention must be
carried out only by qualified and
authorized personnel. Always contact
your Authorized Maserati Dealer.
Use of the rear seat belts
The rear seat belts must be fastened as
shown in the figure.
Remember that, in the event
of a violent collision,
passengers in the back seat
who are not wearing seat belts not
only take a serious personal risk but
are also a danger to passengers in the
front seats.
Wear the seat belts with your back in
an upright position and leaning
against the seatback. When the back
seats are not occupied, fasten the seat
belt buckles into their relative seats.
