Protection of the environment
Note
Environmental note
H
Daimler's declared policy is one of comprehensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmentally responsible manner.
Energy consumption and the rate of engine,
transmission, brake and tire wear depend on
the following factors:
R
operating conditions of your vehicle
R
your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R
always make sure that the tire pressures
are correct.
R
do not carry any unnecessary weight.
R
keep an eye on the vehicle's energy consumption.
R
remove roof racks once you no longer need
them.
R
a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R
always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R
drive carefully and maintain a safe distance
from the vehicle in front.
R
avoid frequent, sudden acceleration and
braking.
Environmental note
H
Have a defective high-voltage battery disposed of in an environmentally-responsible
manner. Contact a qualified specialist workshop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use an authorized Mercedes-Benz Center
for this purpose.
Environmental concerns and recommendations
When prompted to dispose of materials by
this Operator's Manual, always try to re-use
or recycle them first. Observe the relevant
environmental rules and regulations when
disposing of materials. In this way you will
help to protect the environment.
Genuine Mercedes-Benz parts
Environmental note
H
Daimler AG also supplies reconditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the
same Limited Warranty entitlements as new
parts.
Air bags and Emergency Tensioning Devi-
!
ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
R
doors
R
door pillars
R
door sills
R
seats
R
cockpit
R
instrument cluster
R
center console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint systems.
Have aftermarket accessories installed at a
qualified specialist workshop.
Z
Introduction
20
You could jeopardize the operating safety of
your vehicle if you use parts, tires and wheels
as well as accessories relevant to safety
which have not been approved by Mercedes.
This could lead to malfunctions in safety-relevant systems, e.g. the brake system. Use
only genuine Mercedes-Benz parts or parts of
equal quality. Only use tires, wheels and
accessories that have been specifically
approved for your vehicle.
Genuine Mercedes-Benz parts are subject to
strict quality control. Every part has been specifically developed, manufactured or selected
for and adapted to Mercedes-Benz vehicles.
Only genuine Mercedes-Benz parts should
therefore be used.
More than 300,000 different genuine
Mercedes-Benz parts are available for
Mercedes-Benz models.
All authorized Mercedes-Benz Centers maintain a supply of genuine Mercedes-Benz parts
for necessary service and repair work. In addition, strategically located parts delivery centers provide quick and reliable parts service.
Always specify the vehicle identification number (VIN) when ordering genuine MercedesBenz parts (Y page 308).

Always have the prescribed service/maintenance work as well as any required repairs
carried out at a qualified specialist workshop.
WARNING
G
If you switch off the ignition while driving,
safety-relevant functions are only available

Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other networked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as intended and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as electronic components or their software. You
should have all work to electrical and electronic equipment carried out at a qualified
specialist workshop.
If you make changes to electronic components, their software or wiring, the general
operating permit for your vehicle may be rendered invalid.
There is a risk of damage to the vehicle if:
!
R
the vehicle becomes stuck, e.g. on a high
curb or an unpaved road
R
you drive too fast over an obstacle, e.g. a
curb or a hole in the road
R
a heavy object strikes the undercarriage
or parts of the chassis
In situations like this, the body, the undercarriage, chassis parts, wheels or tires
could be damaged without the damage
being visible. Components damaged in this
way can unexpectedly fail or, in the case of
an accident, no longer withstand the strain
they are designed to.
In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If on continuing your journey you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to
road and traffic conditions. In such cases,
visit a qualified specialist workshop.

Warning
Vehicles with an electric motor generate
much less driving noise than vehicles with
internal combustion engines. As a result,
when maneuvering or driving at low speeds
for example, your vehicle is not heard by other
Z
Introduction
24
road users until it is very close, or may not
even be heard at all. This is particularly the
case if other road users have not yet seen
your vehicle but are instead relying on hearing. Drive with particular care, allowing for the
possibility that other road users may behave
unpredictably.
The vehicle is equipped with a sound generator. At low speeds, an electric vehicle makes
less noise than a vehicle with a combustion
engine. The sound generator is activated so
that other road users can hear your vehicle
better. The sound generator is activated at
speeds of under 20 mph (30 km/h) and
switches off automatically at higher speeds.

Data stored in the vehicle
Data recording
This vehicle is capable of recording diagnostic
information relating to vehicle operation, malfunctions, and user settings. This may include
information about the performance or status
of various systems, including but not limited
to, engine, throttle, steering or brake systems, that is stored and can be read out with
suitable devices, particularly when the vehicle is serviced. The data obtained is used to
properly diagnose and service your vehicle or
to further optimize and develop vehicle functions.
COMAND/mbrace
If the vehicle is equipped with COMAND or
mbrace, additional data about the vehicle’s
operation, the use of the vehicle in certain
situations, and the location of the vehicle may
be compiled through COMAND or the mbrace
system.
For additional information please refer to the
COMAND User Manual and/or the mbrace
Terms and Conditions.
Event data recorders
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR
is to record data that will assist in understanding how a vehicle’s systems performed
in certain crash or near crash-like situations,
such as during air bag deployment or when
hitting a road obstacle. The EDR is designed
to record data related to vehicle dynamics
and safety systems for a short period of time,
typically 30 seconds or less.
The EDR in this vehicle is designed to record
such data as:
R
how various systems in your vehicle are
operating
R
whether or not the driver and passenger
seat belts are fastened
R
how far (if at all) the driver is depressing the
accelerator and/or brake pedal and
R
how fast the vehicle is traveling
This data can help provide a better understanding of the circumstances in which
crashes and injuries occur. NOTE: EDR data is
recorded by your vehicle only if a non-trivial
crash situation occurs; no data is recorded by
the EDR under normal driving conditions and
no personal data (e.g., name, gender, age,
and crash location) are recorded. However,
other parties, such as law enforcement, can
combine the EDR data with the type of personal identification data routinely acquired
during a crash investigation.
To read data recorded by an EDR, special
equipment is required, and access to the vehicle or the EDR is needed. In addition to the
vehicle manufacturer, other parties that have
the special equipment, such as law enforcement, can read the information by accessing
the vehicle or the EDR.
EDR data may be used in civil and criminal
matters as a tool in accident reconstruction,
accident claims, and vehicle safety. Since the
Crash Data Retrieval CDR tool that is used to
extract data from the EDR is commercially
available, Mercedes-Benz USA, LLC
("MBUSA") expressly disclaims any and all liability arising from the extraction of this information by unauthorized Mercedes-Benz personnel.
MBUSA will not share EDR data with others
without the consent of the vehicle owners or,
if the vehicle is leased, without the consent of
the lessee. Exceptions to this representation
include responses to subpoenas by law
enforcement; by federal, state or local government; in connection with or arising out of
litigation involving MBUSA or its subsidiaries
and affiliates; or, as required by law.
Warning: The EDR is a component of the Supplemental Restraint System ("SRS") Module.
Tampering with, altering, modifying or removing the EDR component may result in a malfunction of the SRS Module and other systems.
State laws or regulations regarding EDRs that
conflict with federal regulation are pre-empted. This means that in the event of such conflict, the federal regulation governs. As of
February 2013, 13 states have enacted laws
relating to EDRs.

Occupant safety
Restraint system: introduction
The restraint system reduces the risk of vehicle 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:
R
Seat belt system
R
Air bags
R
Child restraint system
R
Child 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:
R
have fastened their seat belts correctly
(Y page 43)
R
have adjusted their seat and head restraint
properly (Y page 87).
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 (Y page 86).
You also have to make sure that an air bag can
inflate properly if deployed (Y page 46).
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
example, 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 particular accident
situation are deployed. However, 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 Device and air bags"
(Y page 54).
For more information about children traveling
with you in the vehicle and on child restraint
systems, see "Children in the vehicle"
(Y page 56).

Important safety notes
WARNING
G
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 an air bag 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).
Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and
at regular intervals while the drive system is
running. Therefore, malfunctions can be
detected in good time.
The 6 restraint system warning lamp in
the instrument cluster lights up when the ignition is switched on. It goes out no later than a
few seconds after the drive system is started.
The components of the restraint system are in
operational readiness.
A malfunction has occurred if the 6
restraint system warning lamp:
R
does not light up after the ignition is
switched on
R
does not go out after a few seconds with
the drive system running
R
lights up again while the drive system is
running
DANGER
G
If the restraint system is malfunctioning, individual restraint system components may be
triggered unintentionally or might not be trig-
gered at all in the event of an accident with a
high rate of vehicle deceleration. This could
affect Emergency Tensioning Devices or air
bags, for example. The vehicle's high-voltage
electrical system may also not be deactivated
as intended in the event of an accident. You
could suffer an electric shock if you touch the
damaged components of the vehicle's highvoltage electrical system. This poses an
increased risk of injury or even fatal injury.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. Immediately switch off the ignition
and remove the SmartKey from the ignition
lock after an accident.
PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG OFF indicator lamp :
and PASSENGER AIR BAG ON indicator
lamp ; are part of the Occupant Classification System (OCS).
The indicator lamps display the status of the
front-passenger front air bag.
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 accident.
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.
Safety
Z
Occupant safety
42
Depending on the person in the frontpassenger seat, the front-passenger front air
bag must either be disabled or enabled; see
the following points. You must make sure of
this both before and during a journey.
R
Children in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the
Safety
installed child restraint system, and the age
and size of the child. Therefore, be sure to
observe the notes on the "Occupant Classification System (OCS)" (Y page 49) and
on "Children in the vehicle" (Y page 56).
There you will also find instructions on rearward and forward-facing child restraint systems on the front-passenger seat.
R
All other persons: depending on the classification of the person in the frontpassenger seat, the front-passenger front
air bag is enabled or deactivated
(Y page 49). Be sure to observe the notes
on "Seat belts“ (Y page 42) and "Air bags"
(Y page 46). There you can also find information on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occupants in the event of an accident or the vehicle rolling over. This reduces the risk of vehicle occupants coming into contact with parts
of the vehicle interior or being ejected from
the vehicle. Furthermore, the seat belt helps
to keep the vehicle occupant in the best position in relation to the air bag.
The seat belt system comprises:
R
Seat belts
R
Emergency Tensioning Devices for the
front seat belts and the outer seat belts in
the rear
R
Seat 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
extracted 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
correct an incorrect seat position or the routing of an incorrectly fastened seat belt.
When triggered, seat belt force limiters help
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 occupants during an accident.
If the front-passenger seat is unoccupied,
!
do not insert the belt tongue into the buckle
of the front-passenger seat. This may otherwise lead to the triggering of the Emergency Tensioning Device in the event of an
accident, which will then need to be
replaced.
Important safety notes
The use of seat belts 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
Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey.
WARNING
G
If the seat belt is incorrectly fastened, it cannot protect as intended. Furthermore, an
incorrectly fastened seat belt can cause additional injury, for example, in an accident, during braking or when abruptly changing direc-
Occupant safety
43
tion. This poses an increased risk of injury or
even fatal injury.
Make sure that all vehicle occupants are
seated properly with a correctly fastened seat
belt.
WARNING
G
The seat belt does not offer the intended level
of protection if you have not moved the backrest to an almost vertical position. When braking 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.
WARNING
G
Persons under 5 ft (1.50 m) in height cannot
fasten the seat belt correctly without an additional suitable restraint system. If the seat
belt is incorrectly fastened, it cannot protect
as intended. Furthermore, an incorrectly fastened seat belt can cause additional injury, for
example, in an accident, during braking or an
abrupt change of direction. This poses an
increased risk of injury or even fatal injury.
For this reason, always secure persons under
5 ft (1.50 m) in height in suitable restraint
systems.
If a child younger than 12 years 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 this Mercedes-Benz
vehicle. The child restraint system must be
appropriate to the age, weight and size of
the child
R
always observe the instructions and safety
notes in the "Children in the vehicle" section of this Operator's Manual
(Y page 56) 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 49)
WARNING
G
The seat belts may not perform their intended
protective function if:
R
they are damaged, modified, extremely
dirty, bleach or dyed
R
the seat belt buckle is damaged or
extremely dirty
R
the Emergency Tensioning Devices, belt
anchorages or inertia reels have been modified
Seat belts may sustain non-visible damage in
an accident, e.g. due to glass splinters. Modified or damaged seat belts may tear or fail,
e.g. in an accident. Modified Emergency Tensioning Devices could accidentally trigger or
fail to deploy when necessary. This poses an
increased risk of injury or even fatal injury.
Never modify the seat belts, Emergency Tensioning Devices, belt anchorages or inertia
reels. Make sure that the seat belts are
undamaged, not worn out and clean. Following an accident, have the seat belts checked
immediately at a qualified specialist workshop.
Only use seat belts that have been approved
for your vehicle by Mercedes-Benz. Any such
modifications could invalidate the vehicle's

The 7 seat belt warning lamp in the instrument cluster is a reminder that all occupants
must fasten 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 7 seat belt
warning lamp lights up for six seconds each
time the drive system is started. If the front
doors are closed and the driver or frontpassenger seat belt has not been fastened,
the 7 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
7 seat belt warning lamp goes out.
If the driver's seat belt is not fastened after
the drive system is started, an additional
warning tone will sound. The warning tone
switches off after six seconds or once the

Air bags
Introduction
The installation point of an air bag can be recognized by the AIR BAG symbol.
An air bag complements the correctly fastened seat belt. It is no substitute for the seat
belt. The air bag provides additional protection in applicable accident situations.
Not all air bags are deployed in an accident.
The different air bag systems function independently from one another (Y page 54).
However, no system available today can completely eliminate injuries and fatalities.
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
WARNING
G
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 greatest 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 occupants.
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 position 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 driving. 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
dashboard, 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
systems. 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 12 years of
age and less than 5 ft (1.50 m) in height 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 frontpassenger 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 41).
R
Always observe the instructions and safety
notes on the "Occupant Classification System (OCS)" (Y page 49) and on "Children
in the vehicle" (Y page 56) in addition to
the child restraint system manufacturer's
installation instructions.
Objects in the vehicle interior may prevent the 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 the vehicle within the deployment area 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.
WARNING
G
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.
WARNING
G
Sensors to control the air bags are located in
the doors. Modifications or work not performed correctly to the doors or door paneling, as well as damaged doors, can lead to the
Occupant safety
function of the sensors being impaired. The air
bags might therefore not function properly
any more. 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 paneling carried out at a qualified specialist workshop.
Front air bags
Driver's air bag : deploys in front of the
steering wheel; front-passenger front air
bag ; deploys in front of and above the glove
box.
When deployed, the front air bags offer additional head and thorax protection for the
occupants in the front seats.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps
inform you about the status of the frontpassenger front air bag (Y page 41).
Front-passenger front air bag ; will only

Driver's knee bag
Safety
Driver's knee bag : deploys under the steering column. The driver's knee bag is triggered
together with the 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
WARNING
G
Unsuitable seat covers could restrict or even
prevent the deployment of the air bags integrated into the seats. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. In addition, the function 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.
When deployed, the side impact air bag offers
additional thorax and pelvis 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 frontpassenger side (front) deploys in the following situations:
R
the OCS system detects that the frontpassenger 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 frontpassenger side deploys if an appropriate accident situation occurs. In this case, deployment is independent of whether the frontpassenger seat is occupied or not.
Window curtain air bags
Side impact air bags : deploy next to the
outer bolsters of the seat backrests.
Window curtain air bags : are integrated
into the side of the roof frame and deployed in
the area from the A-pillar to the C-pillar.
When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protect the chest or
arms.
In the event of a side impact, the window curtain air bag is deployed on the side on which
the impact occurs.
Occupant safety
49
If the system determines that they can offer
additional protection to that provided by the
seat belt, a window curtain air bag may be
deployed in other accident situations
(Y page 54).
Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS)
categorizes the person in the front-passenger
seat. Depending on that result, the frontpassenger front air bag is either enabled or
deactivated.
The system does not deactivate:
R
the side impact air bag
R
the window curtain air bag
R
the Emergency Tensioning Devices
Prerequisites
To be classified correctly, the front passenger
must sit:
R
with the seat belt fastened correctly
R
in an almost upright position with their
back against the seat backrest
R
with their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, OCS may produce a false classification, e.g. because the front passenger:
R
transfers their weight by supporting themselves on a vehicle armrest
R
sits 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. cushions. 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.
The child restraint system must not touch the
roof or be put under strain 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
system manufacturer's installation instructions.

bag changes while the vehicle is in motion, an
air bag display message appears in the instrument cluster (Y page 203). When the frontpassenger 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.
WARNING
G
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 frontpassenger seat could then, for example, come
into contact with the vehicle's interior, especially 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 frontpassenger seat is correct and the frontpassenger front air bag is enabled or disabled 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 journey, that the status of the front-passenger
front air bag is correct.
WARNING
G
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 rearward-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 53).
WARNING
G
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 interior if the PASSENGER AIR BAG OFF indicator 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.
Move the front-passenger seat as far back as
possible. Always make sure that the shoulder
belt strap is correctly routed from the vehicle
belt outlet to the shoulder belt guide on the
child restraint system. The shoulder belt strap
must be routed forwards and downwards
from the vehicle belt outlet. If necessary,
adjust the vehicle belt outlet and the frontpassenger seat accordingly. Always observe
the child restraint system manufacturer's
installation instructions.
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
Occupant safety
51
remains lit. This indicates that the frontpassenger front air bag is deactivated.
R
the front-passenger seat is occupied by a
child of up to 12 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 indicates that the front-passenger front air bag
is deactivated.
But in the case of a 12-month-old child in a
standard child restraint system, the
PASSENGER AIR BAG ON can light up permanently after the system self-test. This
indicates 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 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 classification.
-
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 a stature corresponding to that of an adult, 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 56).
When OCS is malfunctioning, the red 6
restraint system warning lamp in the instrument cluster and the PASSENGER AIR BAG
OFF indicator lamp light up simultaneously.
The front-passenger front air bag is deactivated in this case and does not deploy during an
accident. Have the system checked by qualified technicians 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 recommends 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
System (OCS) categorizes the occupant in the
front-passenger seat. Depending on that
result, the front-passenger front air bag is
either enabled or deactivated.

people with asthma or other respiratory problems. 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.
Air bags and pyrotechnic Emergency Tensioning Devices (ETDs) contain perchlorate material, which may require special handling and
regard for the environment. National guidelines must be observed during disposal. In
California, 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 physical data relating to vehicle deceleration or acceleration, such as:
R
duration
R
direction
R
intensity
Based on the evaluation of this data, the
restraint system control unit deploys the
Emergency Tensioning Devices during a frontal or rear collision.
An Emergency Tensioning Device can only be
deployed, if:
R
the ignition is switched on
R
the components of the restraint system are
operational; see "Restraint system warning
lamp" (Y page 41)
R
the belt tongue is engaged in the buckle on
the respective front-passenger seat
The Emergency Tensioning Devices in the
rear compartment are deployed independently of the lock status of the seat belts.
If Emergency Tensioning Devices or air bags
are deployed, you will hear a bang, and a small
amount of powder may also be released. The
6 restraint system warning lamp lights up.
Only in rare cases will the bang affect your
hearing. The powder that is released generally does not constitute a health hazard, but it
may cause short-term breathing difficulties in
Occupant safety
55
If the restraint system control unit detects a
more severe accident, further components of
the restraint system are activated independently of each other in certain frontal collision
situations:
R
Front air bags and driver's knee bag
R
Window curtain air bag, if the system determines that deployment can offer additional
protection to that provided by the seat belt
The front-passenger front air bag is activated
or deactivated depending on the person on
the front-passenger seat. The frontpassenger front air bag can only deploy 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 41).
Your vehicle has two-stage front air bags.
During the first deployment stage, the front
air bag is filled with propellant gas to reduce
the risk of injuries. The front air bag is fully
deployed with the maximum amount of propellant gas if a second deployment threshold
is reached within a few milliseconds.
The deployment threshold of the Emergency
Tensioning Devices and the air bag are determined by evaluating the rate of vehicle deceleration or acceleration which occurs at various points in the vehicle. This process is preemptive in nature. Deployment should take
place in good time at the start of the collision.
The rate of vehicle deceleration or acceleration and the direction of the force are essentially determined by:
R
the distribution of forces during the collision
R
the collision angle
R
the deformation characteristics of the vehicle
R
the characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a
decisive role in the deployment of an air bag,
nor do they provide an indication of air bag
deployment.
The vehicle can be deformed considerably,
without 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 deformation. This is the case if, for
example, very rigid vehicle parts such as longitudinal body members are hit, and sufficient
deceleration occurs as a result.
If the restraint system control unit detects a
side impact or that the vehicle is rolling over,
the relevant restraint system components are
activated independently of one another
depending on the apparent type of accident.
If the system determines a need for additional
protection for the vehicle occupants, the

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 12 years 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
appropriate 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 49)

G
If children are left unsupervised in the vehicle,
they could:
R
open the doors, thus endangering other
people or road users.
R
get out and disrupt traffic.
R
operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R
release the parking brake.
R
shift the transmission out of park position P
R
start the vehicle's drive system.
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 or animals unattended in the

Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety systems can neither reduce the risk of accident
nor override the laws of physics. Driving
safety systems are merely aids designed to
assist driving. You are responsible for the distance to the vehicle in front, for vehicle speed
and for braking in good time. Always adapt
your driving style to suit the prevailing road,
weather and traffic conditions and maintain a
safe distance from the vehicle in front. Drive
carefully.
The driving safety systems described only
i
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Pay particular attention to
the information regarding tires, recommended minimum tire tread depths etc. in the
"Wheels and tires" section (Y page 278).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the driving safety systems described in this section
work as effectively as possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehicle when braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out if the drive system is running.
Important safety notes
Observe the "Important safety notes" sec-
i
tion for driving safety systems (Y page 63).
WARNING
G
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Additionally, further driving safety systems are deactivated. There is an increased danger of skidding and accidents.
Drive on carefully. Have ABS checked immediately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 218) and
display messages which may be shown in the
instrument cluster (Y page 191).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions. ABS works on slippery roads, even if
you only brake gently.
Braking
X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking situation is over.
X
To make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication of hazardous road conditions, and functions as a reminder to take extra care while
driving.
BAS (Brake Assist System)
General information
BAS operates in emergency braking situations. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
Important safety notes
Observe the "Important safety notes" sec-
i
tion (Y page 63).

the wheels from locking.
Safety
Braking
X
Keep the brake pedal firmly depressed until
the emergency braking situation is over.

The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
COLLISION PREVENTION ASSIST
General notes
COLLISION PREVENTION ASSIST comprises
Adaptive Brake Assist and the distance warning signal, which are described in the following.
Distance warning function
Important safety notes
Observe the "Important safety notes" sec-
i
tion for driving safety systems (Y page 63).
WARNING
G
The distance warning function does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
Always pay careful attention to the traffic situation and be ready to brake.
WARNING
G
The distance warning function cannot always
clearly identify objects and complex traffic
situations.
In such cases, the distance warning function
may:
R
give an unnecessary warning
R
not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic situation and do not rely solely on the distance
warning function.
Function
X
To activate/deactivate: activate or deactivate the distance warning function in the
on-board computer (Y page 184).
If the distance warning function is activated,
the multifunction display does not display a
symbol.
When the distance warning function is deactivated, the æ symbol appears in the multifunction display in the assistance graphics
display.
The distance warning function can help you to
minimize the risk of a front-end collision with
a vehicle ahead or reduce the effects of such
a collision. If the distance warning function
detects that there is a risk of a collision, you
will be warned visually and acoustically. The
distance warning function cannot prevent a
collision without your intervention.
Starting at a speed of around 4 mph (7 km/h),
the distance warning function warns you if
you rapidly approach a vehicle in front. An
intermittent warning tone will then sound,
and the · distance warning lamp will light
up in the instrument cluster.
X
Brake immediately in order to increase the
distance from the vehicle in front.
or
X
Take evasive action provided it is safe to do
so.
Driving safety systems
65
Due to the nature of the system, particularly
complicated but non-critical driving conditions may also cause the system to display a
warning.
With the help of the radar sensor system, the
distance warning function can detect obstacles that are in the path of your vehicle for an
extended period of time.
Up to a speed of around 40 mph (70 km/h),
the distance warning function can also react
to stationary obstacles, such as stopped or
parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision,
the system will initially alert you both visually
and acoustically.
In particular, the detection of obstacles can
be impaired if:
R
dirt on the sensors or anything else covering the sensors
R
there is snow or heavy rain
R
there is interference by other radar sources
R
there are strong radar reflections, for
example in parking garages
R
a narrow vehicle traveling in front, e.g. a
motorbike
R
a vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the vehicle, have the configuration and operation of
the radar sensor checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible
damage to the front of the vehicle.
Adaptive Brake Assist
Observe the "Important safety notes" sec-
i
tion for driving safety systems (Y page 63).
WARNING
G
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situations.
In such cases, Adaptive Brake Assist can:
R
intervene unnecessarily
R
not intervene
There is a risk of an accident.
Always pay careful attention to the traffic situation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
WARNING
G
Adaptive Brake Assist does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
to stationary obstacles
R
when cornering
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic situation and be ready to brake.
Due to the nature of the system, particularly
complicated but non-critical driving conditions may also cause Brake Assist to intervene.
Adaptive Brake Assist provides braking assistance in hazardous situations at speeds
above 4 mph (7 km/h). It uses radar sensor
technology to assess the traffic situation.
With the help of Adaptive Brake Assist, the
distance warning signal can detect obstacles
that are in the path of your vehicle for an
extended period of time.
As soon as a risk of a collision is detected,
Adaptive Brake Assist calculates the braking
force necessary to avoid the collision. If you
apply the brakes forcefully, Adaptive Brake
Assist will automatically increase the braking
force to a level suitable for the traffic conditions.
X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
Safety
Z
Driving safety systems
66
The brakes will work normally again if:
R
you release the brake pedal.
R
there is no longer any danger of a collision.
R
there is no longer an obstacle detected in
front of your vehicle.
Adaptive Brake Assist is then deactivated.
Up to a speed of approximately 155 mph
Safety
(250 km/h), Adaptive Brake Assist is capable
of reacting to moving objects that have
already been detected as such at least once
over the period of observation. Adaptive
Brake Assist does not react to stationary
obstacles.
If Adaptive Brake Assist is not available due to
a malfunction in the radar sensor system, the
brake system remains available with full
brake boosting effect and BAS.
In particular, the detection of obstacles can
be impaired if there is:
R
there is dirt on the sensors or anything else
covering the sensors
R
there is snow or heavy rain
R
there is interference by other radar sources
R
there are strong radar reflections, for
example in parking garages
R
a narrow vehicle traveling in front, e.g. a
motorbike
R
a vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the vehicle, have the configuration and operation of
the radar sensor checked at a qualified specialist workshop. This also applies to collisions at slow speeds where there is no visible
damage to the front of the vehicle.
Important safety notes
Observe the "Important safety notes" sec-
i
tion for driving safety systems (Y page 63).
WARNING
G
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified specialist workshop.
Observe information regarding indicator and
warning lamps (Y page 218) as well as display messages (Y page 195).
ESP®(Electronic Stability Program)
General notes
Observe the "Important safety notes" sec-
i
tion (Y page 63).
ESP®monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP®detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The drive system output is also modified to keep the vehicle on the desired course
within physical limits. ESP®assists the driver
when pulling away on wet or slippery roads.
ESP®can also stabilize the vehicle during
braking.
ETS/4ETS (Electronic Traction System)
EBD (electronic brake force distribution)
General information
EBD monitors and controls the brake pressure on the rear wheels to improve driving
stability while braking.
Observe the "Important safety notes" sec-
i
tion (Y page 63).
ETS traction control is part of ESP®.
ETS brakes the drive wheels individually if
they spin. This enables you to pull away and
accelerate on slippery surfaces, for example
if the road surface is slippery on one side. In
Driving safety systems
67
addition, more drive torque is transferred to
the wheel or wheels with traction.
ETS remains active when you deactivate
ESP®.
Important safety notes
WARNING
G
If ESP®is malfunctioning, ESP®is unable to

steering support from STEER CONTROL.
Power steering will, however, continue to
function.
RBS (Recuperative Brake System)
Observe the "Important safety notes" sec-
i
tion for driving safety systems (Y page 63).
RBS converts the kinetic energy when braking
into electrical current. The electric motor is
used as an alternator during braking. The converted energy is then stored in the high-voltage battery.
If the warning light in the instrument cluster is
lit up, there is a motor malfunction or a brake
malfunction.
WARNING
G
In the event of malfunctions in the RBS, the
following may occur:
R
the braking performance of the electric
motor may be either reduced or not effective
R
brake pedal resistance may be lower than
usual
R
pedal travel may be longer than usual
If you do not make an additional effort to apply
the brake yourself, the braking effect may not
be sufficient. There is a risk of an accident.
In the event of this malfunction, continue to
depress the brake pedal. The brake system is
still fully functional.

risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustment system.
WARNING
G
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the
seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat.
WARNING
G
The seat belt does not offer the intended level
of protection if you have not moved the backrest to an almost vertical position. When braking 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.
WARNING
G
If head restraints are not installed and adjusted correctly, they cannot provide protection
as intended. There is an increased risk of
injury in the head and neck area, e.g. in the
event of an accident or when braking.
Always drive with the head restraints installed. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
