Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of vehi-
cle occupants coming into contact with parts of
the vehicle's interior in the event of an accident.
The restraint system can also reduce the forces to which vehicle occupants are subjected during
an accident.
The restraint system comprises:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securing systems
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if, at all times, all
vehicle occupants:
Rhave fastened their seat belts correctly
(Ypage 42)
Rhave the seat and head restraint adjusted
properly (Ypage 91) As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (
Ypage 91).
You also have to make sure that an air bag can
inflate properly if deployed (
Ypage 44).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if, in the event of an accident, the protection
offered by the seat belt is sufficient, the air bags
are not deployed. When an accident occurs, only
the air bags that increase protection in that par- ticular accident situation are deployed. How-
ever, seat belts and air bags generally do not
protect against objects penetrating the vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" (
Ypage 51).
See "Children in the vehicle" for information on
children traveling with you in the vehicle as well
as on child restraint systems (
Ypage 53).
Important safety notes
GWARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify components of the
restraint system to accommodate a person with
disabilities, contact an authorized Mercedes-
Benz Center for details. USA only: for further
information contact our Customer Assistance
Center at 1-800 FOR-MERCEDES
(1‑800‑367‑6372).
Mercedes-Benz recommends that you only use
driving aids which have been approved specifi-
cally for your vehicle by Mercedes-Benz.

occupant in the best position in relation to the
air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices for the front
seat belts and the outer seat belts in the rear
RSeat belt force limiters for the front seat belts
and the outer seat belts in the rear
If the seat belt is pulled out of the belt outlet
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be extrac-
ted any further.
The Emergency Tensioning Device tightens the
seat belt in an accident, pulling the belt close
against the body. However it does not pull the
vehicle occupant back in the direction of the
backrest.
The Emergency Tensioning Device does not cor-
rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, a seat belt force limiter helps to
reduce the force exerted by the seat belt on the
vehicle occupant.
The seat belt force limiters for the front seats are
synchronized with the front air bags, which
absorb part of the deceleration force. This can
reduce the force exerted on the vehicle occu-
pants during an accident.
!If the front-passenger seat is not occupied,
do not engage the seat belt tongue in the
buckle on the front-passenger seat. Other-
wise, in the event of an accident the Emer-
gency Tensioning Device and the side impact
air bag, in addition to other systems, may be
triggered and have to be replaced.
Important safety notes
The use of seat belts and child restraint systems
is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadian provinces
Even where this is not required by law, all vehicle
occupants should correctly fasten their seat
belts before starting the journey.
GWARNING
If the seat belt is not worn correctly, it cannot
perform its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of injury or even fatal injury.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sit-
ting properly.
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if, at all times, all vehicle occupants:
Rhave fastened their seat belts correctly
(Ypage 42)
Rhave the seat and head restraint adjusted
properly (Ypage 91)
GWARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
GWARNING
Persons less than 5 ft (1.50 m) tall cannot
wear the seat belt correctly without an addi-
tional and suitable restraint system. If the
seat belt is not worn correctly, it cannot per-
form its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of injury or even fatal injury.
For this reason, always secure persons under
5 ft (1.50 m) tall in suitable additional restraint
systems.

Requirements
To be classified correctly, the front passenger
must sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their back
against the seat backrest
Rwith their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, OCS may produce a false classifica-
tion, e.g. because the front passenger:
Rtransfers their weight by supporting them-
selves on a vehicle armrest
Rsits in such a way that their weight is raised
from the seat cushion
If it is absolutely necessary to install a child
restraint system on the front-passenger seat, be
sure to observe the correct positioning of the
child restraint system. Never place objects
under or behind the child restraint system, e.g. a
cushion. The entire base of the child restraint
system must always rest on the seat cushion of
the front-passenger seat. The backrest of the
forward-facing child restraint system must lie as
flat as possible against the backrest of the front-
passenger seat.
The child restraint system must not touch the
roof or be subjected to a load by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint sys-
tem manufacturer's instal
lation and operating
instructions.
Operation of Occupant Classification
System (OCS)
:PASSENGER AIR BAG ON indicator lamp
;PASSENGER AIR BAG OFF indicator lamp The indicator lamps inform you whether the
front-passenger front air bag is deactivated or
enabled.
XPress the Start/Stop button once or twice, or
turn the SmartKey to position 1or2 in the
ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul-
taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER AIR BAG ON lights up for 60 sec-
onds, subsequently both indicator lamps are
off (PASSENGER AIR BAG ON and OFF): the
front-passenger front air bag is able to deploy
in the event of an accident.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front-passenger
front air bag. The PASSENGER AIR BAG OFF
indicator lamp may be lit continuously or be off.
If the status of the front-passenger front air bag
changes while the vehicle is in motion, an air bag
display message appears in the instrument clus-
ter (
Ypage 209). When the front-passenger
seat is occupied, always pay attention to the
PASSENG ER AIR BAG OFF i
ndicator lamp. Be
aware of the status of the front-passenger front air bag both before and during the journey.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is
disabled. It will not be deployed in the event of
an accident and cannot perform its intended
protective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
Rthe classification of the person in the front- passenger seat is correct and the front-

sive role in the deployment of an air bag. Nor do
they provide an indication of air bag deploy-
ment.
The vehicle can be deformed considerably, with-
out an air bag being deployed. This is the case if only parts which are relatively easily deformed
are affected and the rate of deceleration is not
high. Conversely, air bags may be deployed even
though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as a result.
If the restraint system control unit detects a side
impact or if the vehicle rolls over, the applicable
components of the restraint system are
deployed independently of each other depend-
ing on the apparent type of accident.
RSide impact air bags on the side where the
impact takes place, independently of the
Emergency Tensioning Device and the use of
the seat belt on the driver's seat and outer
seats in the second row
The side impact air bag on the front-
passenger side deploys under the following
conditions:
-the OCS system detects that the front-
passenger seat is occupied or
-the seat belt buckle tongue is engaged in
the belt buckle of the front-passenger seat
RWindow curtain air bag on the side of impact,
independently of the use of the seat belt andindependently of whether the front-
passenger seat is occupied

determines that deployment can offer addi-
tional protection in this situation
RWindow curtain air bags on the driver's and
front-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer addi-
tional protection to that provided by the seat
belt
iNot all air bags are deployed in an accident.
The different air bag systems work independ-
ently of each other. How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration and the apparent type of accident:
RFrontal collision
RSide impact
RRollover
Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
Rthe hazard warning lamps are activated
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rthe engine is switched off and the fuel supply
is cut off
Rvehicles with mbrace: automatic emergency
call
Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
a child restraint system on a rear seat. Children are generally better protected there.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
Rbe sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions.
Ralways observe the instructions and safety
notes on the "Occupant classification system
(OCS)". (
Ypage 46)
Children in the vehicle53
Safety
Z
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro- tect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in
the vehicle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting
properly. Particular attention must be paid to
children.
Observe the safety notes on the seat belt
(
Ypage 41) and the notes on correct use of seat
belts (Ypage 42).
A booster seat may be necessary to achieve
proper seat belt positioning for children over
40 lbs (18 kg) until they reach a height where a three-point seat belt can be properly fastened
without a booster seat.
Special seatbelt retractor
GWARNING
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt retrac- tor is disabled and the inertia real draws in a
portion of the seat belt. The seat belt cannot
be immediately refastened. There is an
increased risk of injury, possibly even fatal.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions. Reactivate
the special seat belt retractor and secure the
child restraint system properly.
All seat belts in the vehicle, except the driver's
seat belt, are equipped with a special seat belt
retractor. When activated, the special seat belt
retractor ensures that the seat belt cannot
slacken once the child seat is secured.
Installing a child restraint system:
XMake sure you observe the child restraint
system manufacturer's installation instruc-
tions.
XPull the seat belt smoothly from the belt out-
let.
XEngage seat belt tongue in belt buckle.
Activating the special seat belt retractor:
XPull the seat belt out fully and let the inertia
reel retract it again.
While the seat belt is retracting, you should
hear a ratcheting sound. The special seat belt
retractor is enabled.
XPush the child restraint system down so that
the seat belt is tight and does not loosen.
Removing the child restraint system and deac-
tivating the special seat belt retractor:
XMake sure you observe the child restraint
system manufacturer's installation instruc-
tions.
XPress the release button of the seat belt
buckle and guide the seat belt tongue back
towards the belt sash guide.
The special seat belt retractor is deactivated.

Safety
LATCH-type (ISOFIX) child seat secur-
ing system
GWARNING
For LATCH-type (ISOFIX) child restraint sys-
tems in which the child is secured using the
safety belt integrated in the child restraint
system, the maximum permissible weight of
the child and child restraint system together
is 73 lbs (33 kg).
If the child and the child restraint system
together weigh more than 73 lbs (33 kg), the
LATCH-type (ISOFIX) child restraint system
with integrated safety belt no longer offers
sufficient protection. The LATCH-type (ISO-
FIX) child seat securing system may be over-
loaded, and the child may not be restrained in
an accident, for example. This poses an
increased risk of injury or even fatal injury.
If the child and the child restraint system
together weigh more than 73 lbs (33 kg),use
only a LATCH-type (ISOFIX) ch ildrestraint sys-
tem in whic h the ch ild isalso secured with the
veh icle seat belt. Also secure the ch ild
restraint system with the Top Tether belt,if
available.
Regularly check that the permis siblegross
weight of the ch ildtogether with the ch ild
restraint system isstill maintained.
Alwa ys co mply wit h the manufacturer's instal-
lation and operating instructions for the ch ild

!When installing the ch ildrestraint system,
make sure that the seat beltfor the middle
seat does not get tr apped.The seat beltcould
otherwise be damaged.
XInstall the LATCH-type (ISOFIX) child restraint
system on both LATCH-type (ISOFIX) securing
rings :.
LATCH-type (ISOFIX) is a standardized securing
system for specially designed child restraint
systems on the rear seats. LATCH-type (ISOFIX)
securing rings for two LATCH-type (ISOFIX) child
restraint systems are installed on the left and
right of the rear seats.
Non-LATCH-type (ISOFIX) child seats may also
be used and can be installed using the vehicle's
seat belt system. Install the child seat according
to the manufacturer's instructions.
Top Tether
Introduction
Top Tether provides an additional connection
between the child restraint system secured with
a LATCH-type (ISOFIX) system and the vehicle.
This helps reduce the risk of injury even further.
If the child restraint system isequipped with a
Top Tether belt, this should always be used.
Important safety notes
GWARNING
If the rear seat backrests are not locke d,they
could fold forwards in the event of an acci-
dent, heavy braking or sudden changes of
dire ction. As a result, child restraint systems
cannot perform their intended protective
function. Rear seat backrests that are not
locked can also cause additional injuries, e.g.
in the event of an accident. This poses an
increased risk of injury or even fatal injury.
