Overview of occupant safety
In this section, you will learn the most impor-
tant facts about the restraint system compo-
nents of the vehicle.
The restraint system consists of:
R seat belts
R child restraint systems
R LATCH-type (ISOFIX) child seat anchors
Additional protection is provided by:
R SRS (Supplemental Restraint System)
R NECK-PRO head restraints
R air bag system components with:
- PASSENGER AIR BAG OFF indicator lamp
- front-passenger seat with Occupant
Classification System (OCS)
The different air bag systems work independ-
ently of each other. The protective functions
of the system work in conjunction with each
other. Not all air bags are always deployed in an accident. G
WARNING
Modifications to or work improperly conduc-
ted on restraint system components or their
wiring, as well as tampering with interconnec- ted electronic systems, can lead to the
restraint systems no longer functioning as
intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy inadver-
tently or fail to deploy in accidents although
the deceleration threshold for air bag deploy-ment is exceeded. Therefore, never modify
the restraint systems. Do not tamper with
electronic components or their software.
i For information on infants and children
traveling with you in the vehicle restraint
systems for infants and children, see "Chil-
dren in the vehicle" (Y page 58).40
Occupant safetySafety

front air bag inflates in a collision 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 a child
in a rear-facing child restraint in the front-
passenger seat. We therefore strongly rec- ommend that you always place a child in a
rear-facing child restraint on the rear seat.
R If you install a rear-facing child restraint on
the front-passenger seat, make sure the
00730074 indicator lamp is illuminated,
indicating that the front-passenger front air bag is deactivated. Should the 00730074
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the
00730074 indicator lamp while driving to
make sure that the 00730074indicator
lamp is illuminated. If the 00730074indi-
cator lamp goes out or remains out, do not transport a child on the front-passenger
seat until the system has been repaired.
A child in a rear-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 a child in a forward-facing child
restraint on the front-passenger seat:
- move the seat as far back as possible
- use the proper child restraint recommen-
ded for the age, size and weight of the
child
- secure child restraint with the vehicle's
seat belt according to the child seat man-
ufacturer'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.
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 a child restraint system.
R is occupied by a small individual, such as a
young teenager or a small adult.
R is occupied by a child in a child restraint
system whose weight is greater than that of
a typical twelve month old child.
These are examples of when the OCS deacti- vates the front-passenger front air bag. Deac-
tivation takes place although the collision ful- fills the criteria for deploying the driver's air
bag. If the SmartKey is removed from the ignition
lock or is in position
0, the PASSENGER AIR
BAG OFF indicator lamp does not light up. G
WARNING
If the red 0075SRS warning lamp in the
instrument cluster and the 00730074indica-
tor 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-Benz Center.
Only have the seat repaired or replaced at an
authorized Mercedes-Benz Center. Occupant safety

Z

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, a passenger should not posi-
tion him/herself in such a way as to cause the passenger's weight to be lifted from theseat cushion as this may result in the OCS
being unable to correctly approximate the
passenger's weight category.
R Read and observe all warnings in this chap-
ter.
System self-test The PASSENGER AIR BAG OFF indicator lamp
lights up if you:
R turn the SmartKey to position 1or 2in the
ignition lock
R press the KEYLESS-GO Start/Stop button
once or twice on vehicles with KEYLESS-GO
When an adult is sitting correctly on the front-
passenger seat and is categorized by the OCS system as an adult, the PASSENGER AIR BAG
OFF indicator lamp lights up and goes off
again after approximately six seconds.
If the seat is not occupied and the OCS sys-
tem classifies the front-passenger seat as
being empty, the PASSENGER AIR BAG OFF
indicator lamp will continue to light up and not go out. G
WARNING
If the 00730074indicator lamp does not illu-
minate, the system is not functioning. You
must contact an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat.
For more information about the OCS, see
"Problems with the Occupant Classification
System" (Y page 51). G
WARNING
Objects between the seat surface and the
child restraint system could affect OCS oper- ation. This could result in the front-passenger
air bag not functioning as intended during an
accident. This poses an increased risk of
injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. The
entire base of the child restraint system must always rest on the seat cushion of the front-
passenger seat. The backrest of the forwards-
facing child restraint system must, as far as
possible, be resting on the backrest of the
front-passenger seat. Always comply with the child restraint system manufacturer's instal-
lation instructions. 50

WARNING
If the 00730074 indicator lamp does not illuminate or remains out with the weight of a typical 12-
month-old child in a standard child restraint or less, or is unoccupied, on the front-passenger seat, do not transport a child on the front-passenger seat until the system has been repaired. PRE-SAFE
®
(anticipatory occupant
protection system)
Introduction PRE-SAFE
®
takes preemptive measures to
protect occupants in certain hazardous sit-
uations.
Important safety notes !
Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam-
aged.
Despite your vehicle being equipped with the PRE-SAFE ®
system, the possibility of per-
sonal injuries occurring as a result of an acci-
dent cannot be eliminated.
Always adapt your driving style to suit the
prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
Function PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated.
R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely.
R vehicles with the Driving Assistance
package: when BAS PLUS intervenes pow-
erfully or the radar sensor system detects
an imminent danger of collision in certain
situations. PRE-SAFE
®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R on vehicles with memory function for the
front-passenger seat: the front-passenger
seat is adjusted if it is in an unfavorable
position.
R if the vehicle skids, the side windows are
closed so that only a small gap remains.
The panorama roof with power tilt/sliding
panel is completely closed.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pre-tensioning. All settings made by
PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back
slightly when the vehicle is stationary.
The seat belt pre-tensioning is reduced and
the locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. More
information about seat-belt adjustment can
be found under "Seat-belt adjustment"
(Y page 56). NECK-PRO head restraints
The NECK-PRO head restraints increase pro-
tection for the driver's and front passenger's head and neck. In the event of a rear collision
of a certain severity, the NECK-PRO head
restraints on the driver's and the front-
passenger seats are moved forwards and
upwards. This provides better head support. 52
Occupant safetySafety

The ETDs can only be activated when:
R the ignition is switched on
R the restraint systems are operational; see
"SRS warning lamp "( Ypage 41)
R the belt tongue is engaged in the buckle on
each of the lap-shoulder belts in the front
R the front-passenger seat is occupied and
the belt tongue is engaged in the buckle on
the front-passenger side
The ETDs on the seats in the rear compart-
ment are triggered independently of the lock
status of the seat belts.
The Emergency Tensioning Devices are trig-
gered depending on the type and severity of
an accident, if:
R in the event of a head-on or rear-end colli-
sion, the vehicle decelerates or accelerates
rapidly in a longitudinal direction during the initial stages of the impact
R in the event of a side impact, the vehicle
decelerates or accelerates rapidly in a lat-
eral direction on the side opposite the
impact
If the ETDs are deployed, you will hear a bang, and a small amount of powder may also be
released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicate that there
is a fire in the vehicle. The dust might cause
some temporary breathing difficulty for peo-
ple with asthma or other breathing trouble. To avoid this, you may wish to get out of the
vehicle or open the windows as soon as it is
safe to do so. The 0075SRS warning lamp
lights up.
If the seat belt is also equipped with a seat
belt force limiter and this is triggered, the
force exerted by the seat belt on the vehicle
occupant is reduced.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which absorb part of the deceleration force.
This results in the force exerted on the occu-
pant being distributed over a greater area. Children in the vehicle
Child restraint systems
Important safety notes Mercedes-Benz recommends that you always
properly secure all infants and children with a child or infant seat restraint system for the
trip.
The use of seat belts and infant and child
restraint systems is required by law in:
R all 50 states
R the U.S. territories
R the District of Columbia
R all Canadian provinces
Infants and children must always be seated in an appropriate infant or child restraint systemrecommended for the size and weight of the
child. The infant or child restraint system
must be properly secured in accordance with
the manufacturer's instructions.
All infant or child restraint systems must meet
the following standards:
R U.S. Federal Motor Vehicle Safety Stand-
ards 213 and 225
R Canadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system
corresponds to the standards can be found
on an instruction label on the child restraint
system. This confirmation can also be found
in the installation instructions that are inclu-
ded with the child restraint system.
Always read and follow the manufacturer's
instructions when using an infant or child
restraint system or booster seat.
Observe the warning labels in the vehicle inte-
rior or on the infant or child restraint. G
WARNING
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever 58
