65 Safety and Security
Occupant safety
Always sit nearly upright, properly use
the seat belts and appropriate size in-
fant or child restraint system.
Children 12 years old and under must
never ride in the front seat, except in a
Mercedes-Benz authorized
BabySmart
TM1
compatible child seat,
which operates with the BabySmart
TM
system installed in the vehicle to deacti-
vate the passenger 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 fa-
tal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety in-
formation. Be sure to give the buyer this
Operator’s Manual.

Warning!
G
Accident research shows that the safest
place for children in an automobile is in the
rear seat. Should you choose to place a child
12 years old or under in the front passenger
seat of your vehicle, you must properly use
a BabySmart
TM child restraint which will
turn off the passenger front airbag
(
page 74).
iAirbags are designed to activate only in
certain frontal (front airbags) impacts
and in side (head protection window
curtain airbags) impacts which exceed
preset thresholds.
Only during these types of impacts, if of
sufficient severity to meet the deploy-
ment thresholds, will they provide their
supplemental protection.
The driver and passenger should al-
ways wear their seat belts. Otherwise it
is not possible for the airbags to pro-
vide their supplemental protection.
In cases of other frontal impacts, an-
gled impacts, roll-overs, other side im-
pacts, rear collisions, or other
accidents, the airbags will not be acti-
vated. The driver and passengers will
then be protected by the fastened seat
belts.
We caution you not to rely on the pres-
ence of the airbags in order to avoid
wearing your seat belt.
