Seat Belts
Warning: Seat belts should not be worn with straps
twisted.
Warning: Seat belts are designed for adults; infants and
smaller children must be restrained in an approved child
safety seat.
Warning: Each belt assembly must only be used by one
occupant; it is dangerous to put a belt around a child being
carried on the passengers lap. Do not put an adult seat belt
around two children.
Warning: When installed, the seat belt webbing must not
contact any sharp edges which could abrade or cut the
webbing during normal use or in an accident. If necessary,
the webbing must be protected.
Warning: Care should be taken to avoid contamination of
the webbing with polishes, oils and chemicals, and
particularly battery acid. Cleaning may safely be carried out
using mild soap and water. The belt should be replaced if
webbing becomes frayed, contaminated or damaged.
Warning: Wearing your seat belt is crucial to your safety.
Not wearing a seat belt increases chance of serious injury or
death in the event of an accident.
Warning: Be sure that you and your passengers always
fasten their seat belts and use them correctly even though
airbags are provided.

Before Driving
Warning: Reclining the seat back decreases protection
provided by the seat belt in the event of a crash. Adjust the
seat back to an upright position. Make sure that the seat
back is locked in place, otherwise it could move forward in
the event of a sudden stop or crash and cause injury.
Warning: Seat belts are designed to bear upon the bony
structure of the body, and should be worn low across the
front of the pelvis, chest and shoulders; wearing the lap
section of the belt across the abdominal area must be
avoided.
Warning: Never place the shoulder portion of belt under
your arm or behind your back.
Warning: Always remove rigid or breakable objects i.e.
spectacles or a mobile phone, from your pockets. These
items could be trapped under seat belts, possibly causing
injury in the event of an accident.
Warning: Expectant mothers should seek medical advice
on the most appropriate way to wear the seat belt.
Warning: Seat belts must be kept clean so that the
retractor works correctly. Make sure that belt webbing is not
twisted, looped, frayed or obstructed in any way. If in doubt
about condition or operation of seat belt installation, have it
checked by your Aston Martin Dealer.
