systemSpecial BabySmart
TM compatible child 
seats, designed for use with the 
Mercedes-Benz system and available at 
any authorized Mercedes-Benz Center are 
required for use with the BabySmart
TM air-
bag deactivation system. With the special 
child seat properly installed, the passenger 
front airbag will not deploy.
The PASS. AIRBAG OFF indicator lamp lo-
cated in the center console will be illumi-
nated, except with the SmartKey removed 
or in starter switch position0.
Infants and small children should never 
share a seat belt with another occupant. 
During an accident, they could be crushed 
between the occupant and seat belt.
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.
Children too big for child restraint systems 
must ride in back seats using regular seat 
belts. Position shoulder belt across chest 
and shoulder, not face or neck. A booster 
seat may be necessary to achieve proper 
belt positioning for children from 41 lbs until 
they reach a height where a lap/shoulder 
belt fits properly without a booster.
When the child restraint is not in use, re-
m o v e  i t  f r o m  t h e  v e h i c l e  o r  s e c u r e  i t  w i t h  t h e  
seat belt to prevent the child restraint from 
becoming a projectile in the event of an ac-
cident.
Do not leave children unattended in the ve-
hicle; even if the children are secured in a 
child restraint system. Unsupervised chil-
dren in a child restraint system may use ve-
hicle equipment and may cause an accident 
and/or serious personal injury.
iThe system does not deactivate the 
side impact airbag and the emergency 
tensioning device.
