or if the front-passenger seat is classified as
being empty.
When the OCS senses that the front-
passenger seat occupant is classified as
being up to or less than the weight of atypical
12-month-old child in astandard child
restraint ,the 000F000B indicator lamp will
illuminate when the engine is started and
remain illuminated, indicating that the front-
passenger front air bag is deactivated.
When the OCS senses that the front-
passenger seat is classified as being empty,
the 000F000B indicator lamp will illuminate
when the engine is started and remain

When the OCS senses that the front-
passenger seat occupant is classified as
being heavier than the weight of atypical 12-
month-old child seated in astandar dchild
restraint or as being asmall individual (such
as ayoung teenager or asmall adult), the
000F000B indicator lamp willi lluminate for
approximatel y6seconds when the engine is
started and then ,depending on occupant
weight sensor readings from the front-
passenger seat, remain illuminated or go out.
With the 000F000B indicator lamp
illuminated, the front-passenger fron tair bag
is deactivated. With the 000F000Bindicator
lamp out, the front-passenge rfront air bag is

WARNING
Accordin gtoacciden tstatistics, childre nare
safe rwhen properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommendt hat children be
placed in the rear seats whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriate infant
restraint,t oddler restraint,orb ooster seat
recommended for the size and weight of the
child.

an inflating air bag. 48
Occupant safetySafety

Note the following important information if it
is necessary to carry achild on the front-
passenger seat:
R Your vehicle is equipped with air bag
technology designed to deactivate the
front-passenger front air bag and the front-
passenger knee bag in yourv ehicle when
the system senses the weight of atypical
12-month-old child or less along with the
weight of astandar dappropriate child
restraint on the front-passenger seat.
R Ac hild in arear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates in acollision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to eliminate
this risk completely is never to place achild
in ar ear-facing child restraint in the front-
passenger seat. We therefore strongly
recommendt hat you always place achild
in ar ear-facing child restraint on the rear
seat.
R If you install arear-facing child restraint on
the front-passenger seat, make sure the
000F000B indicator lamp is illuminated,
indicating that the front-passenger front air
bag and front-passenger knee bag are
deactivated. Should the 000F000B
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodicall ycheck the
000F000B indicator lamp while driving to
make sure that the 000F000Bindicator
lamp is illuminated. If the 000F000B
indicator lamp goes out or remains out, do
not transport achild on the front-passenger
seat until the system has been repaired.
Ac hild in arear-facing child restraint on the
front-passenger seat could be seriously
injured or even killed if the front-passenger
front air bag is deployed. R
If you place achild in aforward-facing child
restraint on the front-passenger seat:
- move the seat as far back as possible
- use the proper child restraint
recommended for the age, size and
weight of the child
- secure child restraint with the vehicle's
seat belt according to the child seat
manufacturer's instructions
R For children larger than the typical 12-
month-old child, the front-passenger front
air bag and the front-passenger knee bag
may or may not be activated. G
WARNING
If the red 0012SRS warning lamp in the
instrumentc luster and the 000F000B
indicator lamp light up simultaneously ,the
OCS is malfunctioning. The front passenger
front air bag and the front passenger knee bag
will be deactivated in this case. Have the
system checked by qualified technicians as
soon as possible. Contact an authorized
Mercedes-Ben zCenter.
Only have the seat repaired or replaced at an
authorized Mercedes-Ben zCenter.
In order to ensure proper operation of the air
bag system and OCS:
R Sit with the seat belt properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
R When seated, apassenger should not
position him/herself in such away as to
cause the passenger' sweight to be lifted
from the seat cushion as this may result in
the OCS being unable to correctly
approximat ethe passenger' sweight
category.
R Read and observe all warnings in this
chapter. Occupant safety

Correct use of th
eseat belts G
WARNING
US ES EATB ELTS PROPERLY
R Seat belt scan only work when used
properly. Never wear seat belt sinany other
way than as describe dinthiss ection, as
that coul dresult in serious injuries in the
event of an accident.
R Eac hoccupan tshould wear their seat belt
at all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver front air bag, driver's side knee
bag, front-passenger front air bag, side
impact air bags, pelvis air bags, window
curtain air bags for the side windows),
EmergencyT ensioning Devices, seat belt
force limiters, and front seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air bags,
driver's side knee bag and ETDs) and side
(side impact air bags, window curtain air
bags, and ETDs) impacts which exceed
preset deployment thresholds and in
certain rollovers (window curtain air bags
and ETDs).
R Never wear the shoulder belt under your
arm, across your neck or off your shoulder.
In af rontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder. It should not
touch the neck.N ever pass the shoulder
portion of the seat belt under your arm. For
this purpose, you can adjust the height of
the seat belt outlet. R
Position the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your
abdomen, it could cause serious injuries in
ac rash.
R Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys etc., as
these might cause injuries.
R Make sure the seat belt is alway sfitted
snugly. Take special care of this when
wearing loose clothing.
R Never use aseat belt for more than one
person at atime. Do not fasten aseat belt
around aperson and another person or
other objects at the same time.
R Seat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distribut eimpact forces.
The twisted seat belt against yourb ody
could cause injuries.
R Pregnant women should also alwaysu se a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible on
the hips to avoid any possible pressure on
the abdomen.
R Place the seat backrest in aposition that is
as upright as possible.
R Check your seat belt during travel to make
sure it is properly positioned.
R Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
R When using aseat belt to secure infant
restraints, toddler restraints, or children in
booster seats, alwaysf ollow the child seat
manufacturer' sinstructions.
Fastening seat belts G
WARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
