58 Safety and SecurityOccupant safety
Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the airbag cover on
the steering wheel must be at least ten
inches (25 cm) or more. You should be
able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see your authorized
Mercedes-Benz Center.
Do not lean with your head or chest
close to the steering wheel or dash-
board.
Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front airbag inflates.
Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.
Occupants, especially children, should
never lean their heads in the area of the
door where the side airbag inflates. This
could result in serious injuries or death
should the airbag be triggered. Always
sit upright, properly use the seat belts
and appropriate size infant or child re-
straint system.
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 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 you are responsible
to make the buyer aware of these points. Be
sure to give the buyer this Operator’s Manu-
al.
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.
BabySmart
TM will not, however, turn off any
side impact airbag.
It should be noted that with respect to both
front and rear side impact airbags there is a
possibility for a side airbag related injury if
occupants, especially children, are not prop-
erly seated or restrained when next to a side
airbag which needs to deploy rapidly in a
side impact in order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
side airbag inflates. This could
