Occupant safetyIn this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are:

Seat belts


Emergency tensioning device


Airbags


Child seats


Child seat recognition


Lower anchors and tethers for children
(LATCH)
As independent systems their protective
effects work in conjunction with each oth-
er.The

A malfunction in the system has been de-
tected, if the 1

comes on after the engine was started
or while driving.
For safety reasons, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Center immediately to
have the system checked.

restraint systems is required by law in
most states, the District of Columbia and
all Canadian provinces. Even where this is
not the case, all vehicle occupants should
have their seat belts fastened at all times
when driving or riding in the vehicle.

USE SEAT BELTS PROPERLY

Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this sec-
tion, as that could result in serious inju-
ries in case of an accident.


Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver’s airbag,
front passenger airbag, side impact air-
bags, head protection window curtain
airbags for side windows), ETD (seat belt
emergency tensioning device), and front
seat knee bolsters. The system is de-
signed to enhance the protection of-
fered to properly belted occupants in
certain frontal (front airbags) and side
(side impact and window curtain air-
bags) impacts which exceed preset de-
ployment thresholds and in
certain rollovers (window curtain air-
bags).


Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The
belt would also apply too much force to
the ribs or abdomen, which could se-
verely injure internal organs such as
your liver or spleen.


Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys etc., as these
might cause injuries.


Position the lap belt as low as possible
on your hips and not across the abdo-
m e n . I f t h e b e l t i s p o s i t i o n e d a c r o s s y o u r
abdomen, it could cause serious injuries
in a crash.


Never use a seat belt for more than one
person at a time. Do not fasten a seat
belt around a person and another per-
son or other objects.


Belts should not be worn twisted. In a
crash, you wouldn’t have the full width
of the belt to manage impact forces. The
twisted belt against your body could
cause injuries.


Pregnant women should also use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.


Never place your feet on the instrument
panel or on the seat. Always keep both
feet on the floor in front of the seat.

66 Safety and SecurityOccupant safetySpecial 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

bag deactivation system. With the special

tensioning device.
Warning!
G
The BabySmart
TM airbag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.Warning!
G
When using a BabySmart
TM compatible
child seat on the front passenger seat, the
passenger front airbag will not deploy only if
the PASSENGER AIRBAG OFF indicator lamp
remains illuminated.
Please be sure to check the indicator every
time you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the
light remains out, do not use the
BabySmart
TM restraint to transport children
on the front passenger seat until the system
has been repaired.
