Special 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
seat properly installed, the passenger front

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.

significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
Warning!

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. to
the point where a lap / shoulder belt fits
properly without one.
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.

door mounted side impact airbag, the
window curtain airbags and the emer-
gency tensioning device.
