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.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and Top Tether strap, or lower anchors
and Top Tether strap, fully in accordance with
the child seat manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint,t oddler restraint,orb ooster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place achild in the front-
passenger seat:
R Your vehicle is equipped with air bag
technology designed to deactivate the
front-passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of astandard appropriate
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 48
Occupant safetySafety

in
ar ear-facin gchild restraint on the rear
seat.
R If you install arear-facin gchild restraint on
the front-passenge rseat, make sure the
000E0013 indicator lamp is illuminated,
indicating that the front-passenger fron tair
bag is deactivated. Should the 000E0013
indicator lamp not illuminat eorgoout while
the restraint is installed, please check
installation .Periodically check the
000E0013 indicator lamp while driving to
make sure that the 000E0013indicator
lamp is illuminated. If the 000E0013
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 will be seriously
injured or even killed if the front-passenger
front air bag inflates.
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 may or may not be activated. G
WARNING
If the red 0021SRS warning lamp in the
instrument cluster and the 000E0013
indicator lamp light up simultaneously ,the
OCS is malfunctioning. The front passenger
front air 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-Benz Center. 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. If the SmartKey is removed from the ignition
lock or is in position 0,PASSENGER AIR BAG
OFF indicator lamp 001Adoes not light up.
The Occupant Classification System (OCS)
categorize sthe occupant on the front-
passenge rseat using aweight sensor.
The front-passenger fron tair bag is
deactivated automatically for certain weight
categories.
The PASSENGER AI RBAG OFF indicator lamp
shows yo uthe current status.
The system does not deactivate:
R the side impact ai rbag
R thew indow curtain air bag
R theE me rgency Tensioning Devices Occupant safety
49Safety Z

To be classified correctly, the frontp
assenger
must sit:
R wit hthe seat belt fastened correctly
R in ap ositio nthat is as upright as possible
with their back against the seat backrest
R with their feet on the floor
The OCS weight sensor reading is affected if
the occupant's weight is transferred, e.g. by
leaning on the armrest.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repair work carried out at a
qualified specialist workshop.
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories that have been approved by
Mercedes-Benz.
Both the driver and the front passenger
should always observe the PASSENGER AIR
BAG OFF indicator lamp as an indication of
whether or not the front passenger is
positioned correctly. Observe also the air bag
displaym essages that can be displayed in the
instrumentc luster (Ypage 219).
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy.
The OCS may have detected that the seat:
R is empty or occupied by the weight of a
typical child up to twelve months old,
seated in achild restraint system.
R is occupied by asmall individual, such as a
young teenager or asmall adult.
R is occupied by achild in achild restraint
system whose weight is greater than that
of at ypical twelve montho ld child.
These are examples of when the OCS
deactivates the front-passenger front air bag.
Deactivation takes place although the
collision fulfills the criteria for deploying the
driver's air bag.
For further information ,see "Air bag display
messages" (Y page 219). System self-test G
WARNING
If the 000E0013indicator lamp does not
illuminate, the system is not functioning. You
must contac tanauthorized Mercedes-Benz
Center befor eseatin gany child on the front
passenger seat. G
WARNING
Never place anything betwee nseat cushion
and child seat (e.g. apillow), since it reduces
the effectiveness of the OCS. The underside
and rear side child restraint system must be
placed entirely on the seat cushion and the
backrest of the front-passenger seat
backrest.
If necessary, adjust the tilt of the passenger
seat backrest.
An incorrectly mounted child seat could cause
injuries to the child in case of an accident,
instead of increasing protection for the child.
Follow the manufacturer's instructions for
installation of child restraint systems.
The PASSENGER AIR BAG OFF indicator lamp
lights up:
R if you turn the SmartKey in the ignition lock
to position 1or 2
R if an adult is seated properly on the front-
passenger seat and the OCS classifies the
occupant as an adult
The PASSENGER AIR BAG OFF indicator
lamp goes out again after approximately six
seconds.
If the seat is not occupied and the OCS
detects that the front-passenger seat is
empty, the PASSENGER AIR BAG OFF
indicator lamp will continue to light up. The
PASSENGER AIR BAG OFF indicator lamp
will not go out.

The distance warning function can help you
to minimize the risk of afront-end collision
with avehicle ahead or reduce the effectsof
such acollision. If the distance warning
function detectst hat there isarisk of a
collision, you will be warned visuallya nd
acoustically .Without your intervention, the
distanc ewarnin gfunction cannot prevent a
collision.
Starting at aspeed of aroun d4mph
(7 km/h), the distanc ewarnin gfunction
warns you if you rapidly approac havehicle in

will light up in the instrumen tcluster. X
Brake immediately in order to increase the
distanc efromt he vehicle in front.
or
X Take evasiv eaction provided it is safe to do
so.
Due to the nature of the system, particularly
complicated but non-critical driving
conditions may also cause the system to
display awarning.
With the help of the radar sensor system, the
distanc ewarnin gfunction can detect
obstacles that are in the path of your vehicle
for an extende dperiod of time.
Fro mas peed of aroun d40mph (70 km/h),
the distance warning function can also react
to stationary obstacles, such as stoppe dor
parked vehicles.
If you approach an obstacle and the distance
warning function detects arisk of acollision,
the system will initially alert you both visually
and acoustically.
In particular, the detectio nofobstacles can
be impaired if:
R dirt on the sensors or anythin gelse
covering the sensors
R snow or heavy rain
R interferenc ebyother radar sources
R ther eare strong radar reflections, for
example in parkin ggarages
R an arro wvehicle traveling in front, e.g. a
