Wa r n i n g !
Children 12 years old and under must never ride in 
the front seat, except in a Mercedes-Benz 
authorized BabySmart
TM compatible child seat, 
which operates with the BabySmart
TM system 
installed in the vehicle to deactivate the passenger-
side front airbag when it is properly installed. 
Otherwise t hey will be stru ck by t he airbag wh en it 
inflates in a crash. If this happens, serious or fatal 
injury can result.
According to accident statistics, children are safer 
when properly restrained in the rear seating 
positions than in the front seating positions. 
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 child 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.
