Mercedes-Benz S 320 1999 Owner's Manual page 43

Important!
Bring seat backrest to upright
position before recalling a stored
seat/head restraint/steering wheel
and exterior rear view mirror
position, otherwise the front seats
could get forced against a rear seat
and be damaged.
Prior to operating the vehicle,
the driver should adjust the seat
height for proper vision as well as
fore/aft placement and seat back
angle to insure adequate control,
reach, operation, and comfort. The
head restraint should also be
adjusted for proper height. See
also airbag section for proper seat
positioning.
Both the inside and outside rear
view mirrors should be adjusted for
adequate rearward vision.
Fasten seat belts. Infants and
small children should be seated in
a properly secured restraint system
that complies with U.S. Federal
Motor Vehicle Safety Standard 213
and Canadian Motor Vehicle
Safety Standard 213.1.
All seat, head restraint, and rear
view mirror adjustments as well as
fastening of seat belts should be
done before the vehicle is put into
motion.
Warning!
Children 12 years old and
under must never ride in the
front seat, except in a
Mercedes-Benz authorized
BabySmart™ compatible child
seat, which operates with the
BabySmart™ system installed
in the vehicle to deactivate the
passenger side airbag when it
is properly installed. Otherwise
they will be struck by the
airbag when it inflates in a
crash. If this happens, serious
or fatal injury will result.
The back seat is the safest
place for children. Infants and
small children must ride in the
back seats and be seated in an
appropriate infant or child
restraint system, which is
properly secured with the
vehicle's seat belt, fully in
accordance with the seat
manufacturer's instructions.
A child's risk of serious or
fatal injuries is significantly
increased if the child restraints
are not properly secured in the
vehicle and the child is not
properly secured in the child
restraint.
