Mercedes-Benz 500 SL Owner's Manual page 40

Warning!
Children 12 years old and under
must never ride in this vehicle,
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 front 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.
Infants and small children must 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.
Backrest
Folding forward:
Lift lever and fold forwards.
Folding back:
Fold backrest back until it audibly
locks in place.
Warning!
The seat belts provide protection
only with the backrest locked in
place and, therefore, must be locked
in place with the vehicle in motion.
Do not drive the car when the seat-
back is not locked in place.
Note:
If the backrest and seat belt warning
lamp does not go out, but is instead lit
continuously, then a backrest is not
engaged in its lock.
Always provide sufficient room behind
the backrest and fold the backrest all
the way back until it can be heard
locking in place.
The warning lamp goes out as soon as
both backrests are locked in place.
If both backrests are locked in place
and the warning lamp does not go out,
have the system checked at your
authorized Mercedes-Benz dealer
immediately.
