Seat belt adjustment The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. This func-
tion adjusts the driver's and front-passenger
seat belt to the upper body of the occupants.
The belt strap is tightened slightly when: R
the belt tongue is engaged in the buckle and R
the ignition is switched on
The seat-belt adjustment will apply a certain
retraction force if any slack is detected between
the vehicle occupant and the seat belt. Do not
hold on to the seat belt tightly while it is adjust-
ing.
You can switch the seat-belt adjustment on and
off using the multimedia system. Information on
activating and deactivating the seat-belt adjust-
ment function can be found in the Digital Oper-
ator's Manual or in the separate operating
instructions for the multimedia system.
Belt warning for the driver and front
passenger The v seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle occu-
pants must wear their seat belts. It may light up
continuously or flash. In addition, there may be
a warning tone.
Regardless of whether the driver's seat belt has
already been fastened, the v seat belt warn-
ing lamp lights up for six seconds each time the
engine is started. If the front doors are closed
and the driver or front-passenger seat belt has
not been fastened, the v seat belt warning
lamp lights up again after the six seconds. As
soon as the driver's and front-passenger seat
belts are fastened or a front door is opened
again, the v seat belt warning lamp goes out.
If the driver's seat belt is not fastened after the
engine is started, an additional warning tone will
sound. The warning tone switches off after six
seconds or once the driver's seat belt is fas-
tened.
If the vehicle speed exceeds 15 mph (25 km/ h)
an d the driver's or front-passenger seat belt is
not fastened, a warning tone sounds again. The
warning tone sounds with increasing intensity
for a maximum of 60 seconds or until the driver or front passenger have fastened their seat
belts.
If the driver or front passenger unfasten their
seat belt while the vehicle is in motion, the belt
warning automatically reactivates.

Air bags
Introduction The air bag installation point is identified by the
label AIR BAG.
An air bag supplements a correctly fastened
seat belt. However, it is not intended as a sub-
stitute for the seat belt. Air bags provide addi-
tional protection in the event of an accident.
Not all air bags are deployed in an accident. The
various air bag systems work independently of
each other ( Y
page 58).
There is, however, no system available today
that can completely rule out injury or death.
It is also not possible to rule out a risk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes
G WARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants: R
have fastened their seat belts correctly,
including pregnant women R
are sitting correctly and maintain the great-
est possible distance to the air bags R
follow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.Occupant safety 51

R
Adjust the seats properly before beginning
your journey. Always make sure that the seat
is in an almost upright position. The center of
the head restraint must support the head at
about eye level. R
Move the driver's and front-passenger seats
as far back as possible. The driver's seat posi-
tion must allow the vehicle to be driven safely. R
Only hold the steering wheel on the outside.
This allows the air bag to be fully deployed. R
Always lean against the backrest while driv-
ing. Do not lean forwards or lean against the
door or side window. You may otherwise be in
the deployment area of the air bags. R
Always keep your feet in the footwell in front
of the seat. Do not put your feet on the dash-
board, for example. Your feet may otherwise
be in the deployment area of the air bag. R
For this reason, always secure persons less
than 5 ft (1.50 m) tall in suitable restraint sys-
tems. Up to this height, the seat belt cannot
be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes: R
Always secure children under twelve years of
age and less than 5 ft ( 1.50 m) ta ll in suitable
child restraint systems. R
Child restraint systems should be installed on
the rear seats. R
Only secure a child in a rearward-facing child
restraint system on the front-passenger seat
when the front-passenger front air bag is
deactivated. If the PASSENGER AIR BAG OFF
indicator lamp is permanently lit, the front-
passenger front air bag is deactivated
( Y
page 47).R
Always observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" ( Y
page 54) and on "Children in the
vehicle" ( Y
page 62) in addition to the child
restraint system manufacturer's installation
and operating instructions.
Objects in the vehicle interior may prevent
an air bag from functioning correctly. Before
starting your journey and to avoid risks resulting
from the speed of the air bag as it deploys, make
sure that: R
there are no people, animals or objects
between the vehicle occupants and an air
bag. R
there are no objects between the seat, door
and B-pillar. R
no hard objects, e.g. coat hangers, hang on
the grab handles or coat hooks. R
no accessories, such as cup holders, are
attached to th e vehicle within the deployment
a rea of an air bag, e.g. to doors, side windows,
rear side trim or side walls. R
no heavy, sharp-edged or fragile objects are in
the pockets of your clothing. Store such
objects in a suitable place.
G WARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objects
to it.
G WARNING
Sensors to control the air bags are located in
the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to the
function of the sensors being impaired. The air
bags might therefore not function properly
anymore. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door pan-
eling carried out at a qualified specialist work-
shop.

Page 55 of 398
Driver's air bag C deploys in front of the steer-
ing wheel. Front-passenger front air bag D
deploys in front of and above the glove box.
When deployed, the front air bags offer addi-
tional head and thorax protection for the occu-
pants in the front seats.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps inform you about
the status of the front-passenger air bag
( Y
page 47).
The front-passenger front air bag will only
deploy if: R
the system, based on the OCS weight sensor
readings, detects that the front-passenger
seat is occupied ( Y
page 54). The
PASSENGER AIR BAG ON indicator lamp is lit
( Y
page 54) R
the restraint system control unit predicts a
high accident severity
Driver's knee bag
Driver's knee bag C deploys under the steering
column. The driver's knee bag is always
deployed along with the driver's front air bag.
The driver's knee bag offers additional thigh,
knee and lower leg protection for the occupant
in the driver's seat.
Side impact air bags
G WARNING
Unsuitable seat covers could restrict or even
prevent the deployment of the air bags inte-
grated into the seats. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. In addition, the func-
tion of the Occupant Classification System (OCS) could be restricted. This poses an
increased risk of injury or even fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
Front side impact air bags C and rear side
impact air bags D deploy next to the outer bol-
ster of the seat backrest.
When deployed, the side impact air bag offers
additional thorax protection. However, it does
not protect the: R
head R
neck R
arms
In the event of a side impact, the side impact air
bag is deployed on the side on which the impact
occurs.
The side impact air bag on the front-passenger
side (front) deploys under the following condi-
tions: R
the OCS system detects that the front-
passenger seat is occupied or R
the belt tongue is engaged in the belt buckle
of the front-passenger seat
If the belt tongue is engaged in the belt buckle,
the side impact air bag on the front-passenger
side deploys if an appropriate accident situation
occurs. In this case, deployment is independent
of whether the front-passenger seat is occupied
or not.Occupant safety 53

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. R
PASSENGER AIR BAG ON lights up: the front-
passenger front air bag is enabled. If, in the
event of an accident, all deployment criteria
are met, the front-passenger front air bag is
deployed. R
PASSENGER 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 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 ( Y
page 265). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status
of the front-passenger front air bag both before
and during the journey.
G WARNING
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: R
the classification of the person in the front-
passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat R
the front-passenger seat has been moved
back as far back as possible. R
the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct. G WARNING
If you secure a child in a rearward-facing child
restraint system on the front-passenger seat
and the PASSENGER AIR BAG ON indicator
lamp is lit up, the front-passenger front air bag
may deploy in an accident. The child could be
struck by the air bag. This poses an increased
risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been disabled. The PASSENGER AIR
BAG OFF indicator lamp must be lit.
If the PASSENGER AIR BAG OFF indicator lamp
remains off and/or the PASSENGER AIR BAG
ON indicator lamp lights up, do not install a rear-
ward-facing child restraint system on the front-
passenger seat. You can find more information
on OCS under "Problems with the Occupant
Classification System" ( Y
page 58).
G WARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too
close to the dashboard, in the event of an
accident, the child could: R
come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example R
be struck by the air bag if the PASSENGER
AIR BAG ON is lit up
This poses an increased risk of injury or even
fatal injury.
Always move the front-passenger seat as far
back as possible and fully retract the seat
cushion length. Always make sure that the
shoulder belt strap is correctly routed from
the vehicle belt sash guide to the shoulder
belt guide on the child restraint system. The
shoulder belt strap must be routed forwards
and downwards from the vehicle belt sash
guide. If necessary, adjust the vehicle belt
sash guide and the front-passenger seat
accordingly. Always observe the child
restraint system manufacturer's installation
instructions.Occupant safety 55

Page 58 of 398
If OCS determines that: R
the front-passenger seat is unoccupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger front air bag is deactivated. R
the front-passenger seat is occupied by a
child of up to twelve months old, in a standard
child restraint system, the PASSENGER AIR
BAG OFF indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenger front air bag is
deactivated.
But even in the case of a twelve-month-old
child, in a standard child restraint system, the
PASSENGER AIR BAG ON can light up perma-
nently after the system self-test. This indi-
cates that the front-passenger front air bag is
activated. The result of the classification is
dependent on, among other factors, the child
restraint system and the child's stature. It is
recommended that you install the child
restraint system on a suitable rear seat. R
The front-passenger seat is occupied by a
person of smaller stature (e.g. a teenager or
small adult), either the PASSENGER AIR BAG
ON or PASSENGER AIR BAG OFF indicator
lamp lights up and remains lit after the system
self-test depending on the result of the clas-
sification. -
If the PASSENGER AIR BAG ON indicator
lamp lights up, move the front-passenger
seat as far back as possible. Alternatively, a
person of smaller stature can sit on a rear
seat. -
If the PASSENGER AIR BAG OFF indicator
lamp is lit, a person of smaller stature
should not use the front-passenger seat. R
the front-passenger seat is occupied by an
adult or a person of adult stature, the
PASSENGER AIR BAG ON indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger front air bag is activated.
If children are traveling in the vehicle, be sure to
observe the notes on "Children in the vehicle"
( Y
page 62).
When OCS is malfunctioning, the red u
restraint system warning lamp in the instrument
cluster and the PASSENGER AIR BAG OFF indi-
cator lamp light up simultaneously. The front-
passenger front air bag is deactivated in this
case and does not deploy du ri
ng an accident. Have the system checked by qualified techni-
cians as soon as possible. Consult an authorized
Mercedes-Benz Center. The front-passenger
seat should only be repaired at an authorized
Mercedes-Benz Center.
If the front-passenger seat, the seat cover or the
seat cushion is damaged, have the necessary
repair work carried out at an authorized
Mercedes-Benz Center.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat accessories that
have been approved by Mercedes-Benz.
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag will
also deploy. The Occupant Classification Sys-
tem (OCS) categorizes the occupant in the front-
passenger seat. Depending on that result, the
front-passenger front air bag is either enabled or
deactivated.
System self-test
G DANGER
If both the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not light up during the system self-test, the
system is malfunctioning. The front-
passenger front air bag might be triggered
unintentionally or might not be triggered at all
in the event of an accident with high deceler-
ation. This poses an increased risk of injury or
even fatal injury.
In this case the front-passenger seat may not
be used. Do not install a child restraint system
on the front-passenger seat. Have the Occu-
pant Classification System (OCS) checked
and repaired immediately at a qualified spe-
cialist workshop.
G DANGER
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the system self-test, the
front-passenger front air bag is disabled. It will
not be deployed in the event of an accident. In
this case, the front-passenger front air bag
cannot perform its intended protective func-
tion, e.g. when a person is seated in the front-
passenger seat.56
Occupant safety
Safety
Page 59 of 398
That person could, for example, come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash-
board. This poses an increased risk of injury or
even fatal injury.
When the front-passenger seat is occupied,
always ensure that: R
the classification of the person in the front-
passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat R
the person is seated properly with a cor-
rectly fastened seatbelt R
the front-passenger seat has been moved
back as far back as possible
If the PASSENGER AIR BAG OFF indicator
lamp remains lit when it should not, the front-
passenger seat may not be used. Do not
install a child restraint system on the front-
passenger seat. Have the Occupant Classifi-
cation System (OCS) checked and repaired
immediately at a qualified specialist work-
shop.
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 forward-
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.
After the system self-test, the PASSENGER AIR
BAG OFF or PASSENGER AIR BAG ON indicator
lamp displays the status of the front-passenger
front air bag ( Y
page 54). For more information about the OCS, see "Prob-
lems with the Occupant Classification System"
( Y

Deployment of Emergency Tensioning
Devices and air bags
Important safety notes
G WARNING
The air bag parts are hot after an air bag has
been deployed. There is a risk of injury. Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified spe-
cialist workshop as soon as possible.
G WARNING
A deployed air bag no longer offers any pro-
tection and cannot provide the intended pro-58
Occupant safety
Safety
Page 61 of 398
tection in an accident. There is an increased
risk of injury.
Have the vehicle towed to a qualified special-
ist workshop in order to have a deployed air
bag replaced.
It is important for your safety and that of any
passengers to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air bags
continue to perform their protective function for
the vehicle occupants in the event of a crash.
G WARNING
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer opera-
tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency Ten-
sioning Devices which have been triggered
immediately replaced at a qualified specialist
workshop.
An electric motor is used by PRE-SAFE ®
to trig-
ger the tightening of the seat belt in hazardous
situations. This procedure is reversible.
If the Emergency Tensioning Devices or air bags
are deployed, you will hear a bang and a small
amount of powder may also be released. The
u restraint system warning lamp will light up.
Only in rare cases will the bang affect your hear-
ing. The powder released is generally not haz-
ardous to health, it could however cause short-
term breathing difficulties in people with asthma
or other respiratory problems. If it is safe to do
so, you should leave the vehicle immediately or
open a window in order to prevent breathing
difficulties.
Air bags and pyrotechnic Emergency Tensioning
Devices (ET Ds) co ntain perchlorate material,

hich may require special handling and regard
for the environment. Check with your local gov-
ernment’s disposal guidelines. California resi-
dents, see www.dtsc.ca.gov/
HazardousWaste/Perchlorate/index.cfm .Method of operation During the first stage of a collision, the restraint
system control unit evaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as: R
Duration R
Direction R
Intensity
Based on the evaluation of this data, the
restraint system control unit triggers the Emer-
gency Tensioning Devices in the event of a fron-
tal or rear-end collision.
An Emergency Tensioning Device can only be
triggered if: R
the ignition is switched on R
the components of the restraint system are
operational. You can find further information
under "Restraint system warning lamp"
( Y
page 46) R
the belt tongue is inserted into the buckle on
the respective front seat
The Emergency Tensioning Devices in the rear
compartment are triggered independently of the
lock status of the seat belts.
If the restraint system control unit detects a high
accident severity, additional components of the
restraint system are deployed independently of
one another in certain frontal collision situa-
tions: R
Front air bags and driver's knee bag R
Window curtain air bag, if the system deter-
mines that it can offer additional protection to
that provided by the seat belt
Depe nding on the person occupying the front-
p assenger seat, the front-passenger air bag is
activated or deactivated. The front-passenger
front air bag can only be deployed in an accident
if the PASSENGER AIR BAG ON indicator lamp is
lit. Observe the information on the PASSENGER
AIR BAG indicator lamps ( Y
page 47).
Your vehicle has dual-stage front air bags. Dur-
ing the first deployment stage, the front air bag
fills with propellant gas which reduces the risk of
injury. The second stage is then triggered within
milliseconds, filling the front air bag with the
maximum amount of propellant gas.
The deployment thresholds for the Emergency
Tensioning Devices and air bags are calculated
on the basis of the vehicle deceleration or accel-
eration occurring at various points in the vehi-
cle. This process is pre-emptive in nature. TheOccupant safety 59

PRE-SAFE ®
PLUS (anticipatory occu-
pant protection system PLUS)
Introduction PRE-SAFE ®
PLUS is only available in vehicles
with the Driving Assistance package.
Using the radar sensor system, PRE-SAFE ®
PLUS is able to detect that a head-on or rear-end
collision is imminent. In certain hazardous sit-
uations, PRE-SAFE ®
PLUS takes pre-emptive
measures to protect the vehicle occupants.
Important safety notes The intervention of PRE-SAFE ®
PLUS cannot
prevent an imminent collision.
The driver is not warned about the intervention
of PRE-SAFE ®
PLUS.
PRE-SAFE ®
PLUS does not intervene if the vehi-
cle is backing up.
When driving, or when parking or exiting a park-
ing space with assistance from Active Parking
Assist, PRE-SAFE ®
PLUS will not apply the
brakes. Function PRE-SAFE ®
PLUS intervenes in certain situa-
tions if the radar sensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE ®
PLUS takes the following measures
depending on the hazardous situation detected: R
if the radar sensor system detects that a
head-on collision is imminent, the seat belts
are pre-tensioned. R
if the radar sensor system detects that a rear-
end collision is imminent: -
the brake pressure is increased if the driver
applies the brakes when the vehicle is sta-
tionary. -
the seat belts are pre-tensioned.
The PRE-SAFE ®
PLUS braking application is can-
celed: R
if the accelerator pedal is depressed when a
gear is engaged R
if the risk of a collision passes or is no longer
detected R
if DISTRONIC PLUS indicates an intention to
pull away
If the hazardous situation passes without result-
ing in an accident, the original settings are
restored.
Automatic measures after an acci-
dent Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact: R
the hazard warning lamps are activated R
the emergency lighting is activated R

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: R
always 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 R
be sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions R
be sure to observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" ( Y
page 54)
G WARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example: R
release the parking brake. R
shift the automatic transmission out of the
parking position P .R
start 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.
G WARNING
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.
G WARNING
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
( Y
page 48 )a nd the notes on correct use of seat
belts ( Y
page 49).
A booster seat may be necessary to achieve
proper seat belt positioning for children over
41 lb s( 18 kg) until they reach a height where a
three-point seat belt can be properly fastened
without a booster seat.
Special seat belt retractor
G WARNING
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.62
