Protecting the environment
General notes
H
Environmental note
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.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected by these 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
avoid short trips as these increase fuel
consumption.
R
always make sure that the tire pressures
are correct.
R
do not carry any unnecessary weight.
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
do not depress the accelerator pedal
when starting the engine.
R
do not warm up the engine when the vehicle is stationary.
R
drive carefully and maintain a safe distance from the vehicle in front.
R
avoid frequent, sudden acceleration and
braking.
R
change gear in good time and use each
gear only up to Ô of its maximum engine
speed.
R
switch off the engine in stationary traffic.
R
keep an eye on the vehicle's fuel consumption.
Environmental concerns and recommendations
Wherever the operating instructions require
you to dispose of materials, first try to regenerate or re-use them. 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
H
Environmental note
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 Devices, 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

operating efficiency of the restraint systems.
Have aftermarket accessories installed at a
qualified specialist workshop.
You could jeopardize the operating safety of
your vehicle if you use parts, tires and wheels
as well as accessories relevant to safety which
24

Operating safety
Important safety notes
G
WARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions
or system failures. There is a risk of an accident.
Always have the prescribed service/maintenance work as well as any required repairs
carried out at a qualified specialist workshop.
G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact
with hot parts of the exhaust system. There
is a risk of fire.
When driving on an unpaved road or offroad, check the vehicle underside regularly.
In particular, remove trapped plant parts or
other flammable material. Contact a qualified specialist workshop immediately if damage is detected.
G
WARNING
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.
!
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, a speed bump or a pothole in the
road
R
a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the underbody, 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 loads they are
designed to.
If the underbody paneling is damaged, combustible materials such as leaves, grass or
twigs can gather between the underbody
and the underbody paneling. If these materials come in contact with hot parts of the
exhaust system, they can catch fire.
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, consult a
qualified specialist workshop.

ing interference that may cause undesired
operation of the device."
Diagnostics connection
The diagnostics connection is used for connecting diagnostic equipment at a qualified
specialist workshop.
G
WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it may affect the
operation of vehicle systems. As a result,
the operating safety of the vehicle could be
affected. There is a risk of an accident.
Only connect equipment to a diagnostics
connection in the vehicle, which is approved
for your vehicle by Mercedes-Benz.
G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardizes the operating and road safety of the vehicle. There is
a risk of an accident.
Stow all objects securely in the vehicle so
that they do not get into the driver's footwell. When using floormats or carpets, make
sure that they are properly secured so that
they do not slip or obstruct the pedals. Do
not place several floormats or carpets on
top of one another.
!
If the engine is switched off and equipment on the diagnostics connection is used,
the starter battery may discharge.
Connecting equipment to the diagnostics connection can lead to emissions monitoring
information being reset, for example. This may
lead to the vehicle failing to meet the requirements of the next emissions test during the
main inspection.
Qualified specialist workshop
An authorized Mercedes-Benz Center is a
qualified specialist workshop. It has the necessary specialist knowledge, tools and qualifications to correctly carry out the work required
on your vehicle. This is especially the case for
work relevant to safety.

Always have the following work carried out at
an authorized Mercedes-Benz Center:
R
work relevant to safety
R
service and maintenance work
R
repair work
R
alterations, installation work and modifications

Leave warning stickers in position.
Observe the following information when driving your vehicle:
R
the safety notes in this manual
R
technical data for the vehicle
R
traffic rules and regulations
R
laws and safety standards pertaining to
motor vehicles
Information about the REACH decree
The REACH regulation (Regulation (EC) no.
1907/2006, Article 33) lays down an information obligation for substances of very high concern (SVHC).

Event data recorders
USA only:
This vehicle is equipped with an event data
recorder (EDR). This vehicle is equipped with
an event data recorder (EDR). The main purpose of an EDR is to record, in certain crash or
near crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a vehicle's systems performed. 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 were
operating
R
Whether or not the driver and passenger
safety belts were buckled/fastened
R
How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
R
How fast the vehicle was traveling
These data can help provide a better understanding of the circumstances in which
crashes and injuries occur. NOTE: EDR data
are recorded by your vehicle only if a non-trivial crash situation occurs; no data are 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
could combine the EDR data with the type of
personally identifying data routinely acquired
during a crash investigation.
Access to the vehicle and/or the EDR is needed to read data that is recorded by an EDR,
and special equipment is required. In addition
30
Data storage
Introduction
to the vehicle manufacturer, other parties that

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
Restraint System Module. Tampering with,
altering, modifying or removing the EDR component may result in a malfunction of the
Restraint System 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
December 2016, 17 states have enacted laws
relating to EDRs.

Occupant safety
Introduction to the restraint system
The restraint system can reduce 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 includes the following
components:
R
seat belt system
R
air bags
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 the seat and head restraint adjusted
properly (Y page 97)
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 97).
You also have to make sure that an air bag can
inflate properly if deployed (Y page 45).
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 Devices and air bags"
(Y page 53).
See "Children in the vehicle" for information
on children traveling with you in the vehicle as
well as on child restraint systems
(Y page 57).
Important safety notes
G
WARNING
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 specifically for your vehicle by Mercedes-Benz.

Occupant safety
Safety
Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and
at regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp on
the instrument cluster lights up when the ignition is switched on. It goes out no later than a
few seconds after the vehicle 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
engine running
R
lights up again while the engine is running
G
WARNING
If the restraint system is malfunctioning,
restraint system components may be triggered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. This poses an
increased risk of injury or even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop
as soon as possible.
PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp :
and PASSENGER AIR BAG OFF 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 ON lights up for 60
seconds, 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.
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.
If the PASSENGER AIR BAG ON indicator lamp
is off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the frontpassenger front air bag. The PASSENGER AIR
BAG OFF indicator lamp may be lit continuously or be off.
Depending on the person in the frontpassenger seat, the front-passenger front air
bag must either be deactivated 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
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 48) and on
"Children in the vehicle" (Y page 57).
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 front-passenger
seat, the front-passenger front air bag is
enabled or deactivated (Y page 48). Be
sure to observe the notes on "Seat
belts“ (Y page 41) and "Air bags"
(Y page 45). 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 occu-
Occupant safety
41
Safety
Z
pants 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 and seat belt
force limiters
If the seat belt is pulled quickly or sharply by
the seat belt guide, the inertia reel 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, a seat belt force limiter helps
to reduce the force exerted by the seat belt on
the vehicle occupant.
The seat belt force limiters 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 not occupied,
do not engage the seat belt tongue in the
buckle on the front-passenger seat. Otherwise, in the event of an accident the Emergency 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:
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.
G
WARNING
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 accident 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 sitting 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:
R
have fastened their seat belts correctly
(Y page 43)
R
have the seat and head restraint adjusted
properly (Y page 97)
G
WARNING
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.
G
WARNING
Persons less than 5 ft (1.50 m) tall cannot
wear the seat belt correctly without an additional and suitable restraint system. 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 accident 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.
42
Occupant safety
Safety
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 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 on "Children in the vehicle"
(Y page 57) in addition to the child
restraint system manufacturer's installation
and operating instructions
R
always observe the instructions and safety
notes on the "Occupant Classification System (OCS)" (Y page 48)
G
WARNING
The seat belts may not perform their intended protective function if:
R
they are damaged, modified, extremely
dirty, bleached 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 be damaged in an accident,
although the damage may not be visible, e.g.
due to splinters of glass. 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 and 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.
Proper use of the seat belts
Observe the safety notes on the seat belt
(Y page 42).
Every vehicle occupant must observe the following notes to ensure a properly worn seat
belt can provide full protection. Also make
sure that all vehicle occupants are always
wearing the seat belt correctly while the vehicle is in motion.
When fastening the seat belt, always make
sure that:
R
the seat belt buckle tongue is inserted only
into the belt buckle belonging to that seat
R
the seat belt is pulled tight across your body
Avoid wearing bulky clothing, e.g. a winter
coat.
R
the seat belt is not twisted
Only then can the forces which occur be dis-
tributed over the area of the belt.
R
the shoulder section of the belt is routed
across the center of your shoulder
The shoulder section of the seat belt should
not touch your neck or be routed under your
arm or behind your back.
R
the lap belt is taut and passes across your
lap as low down as possible
The lap belt must always be routed across
your hip joints and not across your abdomen. This applies particularly to pregnant
women. If necessary, push the lap belt down
to your hip joint and pull it tight using the
shoulder section of the belt.
R
the seat belt is not routed across sharp,
pointed or fragile objects
If you have such items located on or in your
clothing, e.g. pens, keys or eyeglasses,
store these in a suitable place.
R
only one person is using a seat belt
Infants and children must never travel sit-
ting on the lap of a vehicle occupant. In the
event of an accident, they could be crushed
between the vehicle occupant and seat belt.
R
objects are never secured with a seat belt if
the seat belt is also being used by one of
the vehicle's occupants
Also ensure that there are never objects
between a person and the seat, e.g. cushions.
Seat belts are only intended to secure and
restrain vehicle occupants. Always observe the
notes in the "Stowage options/compartments"

Seat belt adjustment
The belt adjustment is a convenience function
integrated into PRE-SAFE®. With this function,
the driver's and front-passenger seat belts are
adjusted to the upper body of the vehicle
occupant.
The seat belt strap will slightly tighten if:
R
the belt tongue is inserted into the buckle
and
R
the ignition is switched on
The seat belt adjustment will apply a certain
tightening force if any slack is detected
between the vehicle occupant and the seat
belt. Do not grab hold of the seat belt.
The belt adjustment can be switched on and
off using the on-board computer
(Y page 202).
Belt warning for the driver and front
passenger
The 7 seat belt warning lamp in the instrument cluster is a reminder that all vehicle
occupants 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 7 seat belt
warning lamp lights up for six seconds each
time the engine is started. If the doors are
closed and the driver's or front-passenger 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 frontpassenger seat belts are fastened or a front

passenger seat belts are not fastened, a warning tone sounds. A warning tone also sounds
with increasing intensity for 60 seconds or
until the driver or front passenger have fastened their seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt
warning is activated again.
Air bags
Introduction
The installation point of an airbag can be recognized by the AIRBAG marking.
An airbag complements the correctly fastened
seat belt. It is no substitute for the seat belt.
When deployed, an airbag can increase the
protection provided for the respective vehicle
occupant.
Not all airbags are deployed in an accident.
The various airbags work independently of
each other (Y page 53).
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 airbag due to the high speed at
which the airbag 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
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.
All vehicle occupants must observe the following notes to avoid risks posed by the airbag
when it deploys.
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 airbag to be fully deployed.
R
Always lean against the backrest while driving. Do not lean forward or lean against the
door or side window. You may otherwise be
in the deployment area of the airbags.
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 airbag.
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 twelve years
of age and less than 5 ft (1.50 m) tall in suitable child restraint systems.
R
Secure a child to the front-passenger seat
only when the front-passenger front airbag
is deactivated, and then only in a rearwardfacing child restraint system. The frontpassenger front airbag is deactivated when
the PASSENGER AIR BAG OFF indicator
lamp is lit continuously (Y page 41).
R
Always observe the instructions and safety
notes on the "Occupant Classification System (OCS)" (Y page 48) and on "Children
in the vehicle" (Y page 57) in addition to
the child restraint system manufacturer's
installation and operating instructions.
Objects in the vehicle interior may restrict
the airbag from functioning correctly. To
avoid risks resulting from the speed of the airbag as it deploys, vehicle occupants must
ensure the following points.
Occupant safety
45
Safety
Z
Before commencing your journey, ensure that:
R
there are no people, animals or objects
between the vehicle occupants and an airbag
R
there are no objects between the seat, door
and B-pillar
R
there are no hard objects, e.g. coat hangers,
hanging 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 airbag, e.g. to doors or side
windows
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 cover of an air bag or affix
objects such as stickers to it, the air bag
can no longer perform its intended function.
There is an increased risk of injury.
Never modify the cover of an air bag or affix
objects to it.
G
WARNING
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 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 paneling carried out at a qualified specialist workshop.
Front air bags
!
Do not place heavy objects on the frontpassenger seat. This could cause the system to identify the seat as being occupied.
In the event of an accident, the restraint
systems on the front-passenger side may be
triggered and have to be replaced.
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 driver's and front-passenger
seats.
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the frontpassenger front air bag (Y page 41).
The front-passenger front air bag will only
deploy if:
R
the system, based on the OCS weight sensor readings, detects that the frontpassenger seat is occupied (Y page 48).
The PASSENGER AIR BAG OFF indicator
lamp is not lit (Y page 48)
R
the restraint system control unit predicts a
high accident severity
Knee bags
Driver's knee bag : deploys under the steering column and front-passenger knee bag ;
under the glove box. The driver's and frontpassenger knee bags are triggered together
with the front air bags.
46
Occupant safety
Safety
The driver's and front-passenger knee bags
offer additional thigh, knee and lower leg protection.
Side impact air bags
G
WARNING
Unsuitable seat covers can obstruct or prevent 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 operation of the occupant classification system
(OCS) could be adversely affected. 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.
Side impact air bags : deploy next to the
outer bolster 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
If the restraint system control unit detects 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 deploys under the following conditions:
R
the OCS system detects that the front
passenger seat is occupied or
R
the seat belt buckle 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.
Head air bags
Head bags : deploy in the area of the side
windows at the front.
When deployed, the head bag enhances the
level of protection for the head. However, it
does not protect the:
R
chest
R
arms
If the restraint system control unit detects a
side impact, the head bag is deployed on the
side on which the impact occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a head bag may be deployed in other
accident situations (Y page 53).
The head bag on the front-passenger side
deploys under the following conditions:
R
the OCS system detects that the frontpassenger seat is occupied or
R
the seat belt buckle tongue is engaged in
the belt buckle of the front-passenger seat
If the belt tongue is engaged in the belt
buckle, the head 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 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 and front-passenger
knee bag are either enabled or deactivated.
The system does not deactivate:
R
the side impact air bag
R
the headbag
R
the Emergency Tensioning Devices
Requirements
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 you 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. Fully
retract the seat cushion length. The entire
base of the child restraint system must always
rest on the seat cushion of the frontpassenger seat. The backrest of the forwardfacing child restraint system must lie as flat as
possible against the backrest of the frontpassenger 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
system manufacturer's installation and operating instructions.

X
Press the Start/Stop button once or twice,
or turn the SmartKey to position 1 or 2 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 simultaneously for approximately six
seconds.
The indicator lamps display the status of the
front-passenger front air bag.
R
PASSENGER AIR BAG ON lights up for
60 seconds, 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.
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.
If the PASSENGER AIR BAG ON indicator lamp
is off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the frontpassenger 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 cluster (Y page 215). When the frontpassenger seat is occupied, always pay attention to the PASSENGER AIR BAG OFF indicator
lamp. Be aware of the status of the front-
48
Occupant safety
Safety
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, 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
front-passenger seat is correct and the
front-passenger 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.
G
WARNING
If you secure a child in a rearward-facing
child restraint system on the frontpassenger seat and the PASSENGER AIR
BAG OFF indicator lamp is off, the frontpassenger front air bag can deploy in the
event of 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 deactivated. The PASSENGER
AIR BAG OFF indicator lamp must be lit.
NEVER use a rearward-facing child restraint
on a seat protected by an ACTIVE FRONT
AIRBAG in front of it; DEATH or SERIOUS
INJURY to the child can occur.
If the PASSENGER AIR BAG OFF indicator lamp
stays off, 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 51).
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 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 OFF indicator lamp
is off
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 seat belt guide to the shoulder
belt guide on the child restraint system. The
shoulder belt strap must be routed forwards
and downwards from the seat belt guide.
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 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 self-test and remains lit. This indicates
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 OFF indicator
lamp can go out after the 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
Occupant safety

Safety
Z
child restraint system and the child's stature. Make sure that the conditions for a correct classification are met. If the
PASSENGER AIR BAG OFF indicator lamp
remains off, do not install a child restraint
system on the front-passenger seat.
R
The front-passenger seat is occupied by a
person of smaller stature (e.g. a teenager or
small adult), the PASSENGER AIR BAG OFF
indicator lamp either lights up and remains
lit after the self-test depending on the result
of the classification or, alternatively, goes
out.
-
If the PASSENGER AIR BAG OFF indicator
lamp is off, move the front-passenger seat
as far back as possible.
-
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 corresponding stature,
the PASSENGER AIR BAG OFF indicator
lamp goes out after the self-test. 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 57).
When the Occupant Classification System
(OCS) is malfunctioning, the red 6 restraint
system warning lamp on the instrument cluster and the PASSENGER AIR BAG OFF indicator lamp light up simultaneously. The frontpassenger front air bag is deactivated in this
case and does not deploy during an accident.
Have the Occupant Classification System
(OCS) checked and repaired immediately at a
qualified specialist workshop. Mercedes-Benz
recommends that you use an authorized
Mercedes-Benz Center for this purpose.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the necessary repair work carried out at a qualified
specialist workshop. Mercedes-Benz recommends that you use an authorized MercedesBenz Center for this purpose.
For safety reasons, Mercedes-Benz recommends that you only use seat accessories that
have been approved by Mercedes-Benz.
Deployment of the driver's air bag does not
mean that the front-passenger front air bag
deploys as well. The Occupant Classification
System (OCS) categorizes the occupant on the
front-passenger seat. Depending on that
result, the front-passenger front air bag is
either enabled or deactivated.

G
DANGER
If the roll bar has developed a malfunction, it
may not function, e.g. in the event of an
accident. The roll bars may then not protect
the vehicle occupants as intended. This
poses an increased risk of injury or even
fatal injury.
Have roll bars checked immediately at a

52
Occupant safety
Safety
The roll bars are located in the rear area of the
vehicle under the two outer rear compartment
trim covers.
They extend if systems detect that the vehicle

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 specialist workshop as soon as possible.
G
WARNING
A deployed air bag no longer offers any protection and cannot provide the intended protection in an accident. There is an increased
risk of injury.
Have the vehicle towed to a qualified specialist workshop in order to have a deployed
air bag replaced.
For your own safety and that of your front
passenger, it is important that you have
deployed air bags replaced and defective 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
Emergency Tensioning Devices that have
deployed pyrotechnically are no longer
operational and are unable to perform their
intended protective function. This poses an
increased risk of injury or even fatal injury.
Have pyrotechnically triggered Emergency
Tensioning Devices replaced immediately at
a qualified specialist workshop.
An electric motor is used by PRE-SAFE®to
trigger the tightening of the seat belt in hazardous situations. This procedure is reversible.
If Emergency Tensioning Devices are triggered
or air bags are deployed, you will hear a bang,
and some 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 people with asthma or other respiratory problems.
Provided it is safe to do so, you should leave
the vehicle immediately or open the window in
order to prevent breathing difficulties.
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 triggers the Emergency Tensioning Devices during a head-on or
rear-end collision.
Occupant safety
53
Safety
Z
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 41)
R
the seat belt buckle tongue has engaged in
the belt buckle of the respective seat
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 as well as driver's and frontpassenger knee bags
Depending on the person in the frontpassenger seat, the front-passenger front air
bag is either enabled or disabled. The frontpassenger front air bag can be deployed in an
accident only if the PASSENGER AIR BAG OFF
indicator lamp is off. Observe the information
on the PASSENGER AIR BAG indicator lamps
(Y page 41).
Your vehicle has two-stage front air bags.
The activation threshold of the Emergency
Tensioning Devices and the air bags is determined by evaluating the rate of vehicle deceleration or acceleration which occurs at various
points in the vehicle. This process is pre-emptive 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 if the vehicle rolls over, the
applicable components of the restraint system
are deployed independently of each other
depending on the apparent type of accident.
R
Side impact air bag on the side of impact,
independently of the Emergency Tensioning
Device and the use of the seat belt on the
driver's seat
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
R
Head bag on the side of impact, independently of the use of the seat belt and independently of whether the front-passenger

R
Head bags on the driver's and frontpassenger side in certain situations when
the vehicle rolls over, if the system determines that deployment can offer additional
protection to that provided by the seat belt
i
Not all air bags are deployed in an accident. The different air bag systems work
independently of each other.
How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or acceleration and the apparent type of accident:

NECK-PRO head restraints
Important safety notes
G
WARNING
The function of the head restraint may be
impaired if you:
R
attach objects such as coat hangers to
the head restraints, for example
R
use head restraint covers
If you do so, the head restraints cannot fulfill
their intended protective function in the
event of an accident. In addition, objects
attached to the head restraints could endanger other vehicle occupants. There is an
increased risk of injury.
Do not attach any objects to the head
restraints and do not use head restraint covers.
Method of operation
NECK-PRO head restraints reduce the likelihood of head and chest injuries. The NECKPRO head restraints on the driver's and frontpassenger seats are moved forwards and
upwards in the event of a rear-end collision of
a certain severity. This provides better head
support.
If the NECK-PRO head restraints have been
triggered in an accident, you must reset the
NECK-PRO head restraints on the driver’s and
front-passenger seat (Y page 55). Otherwise, the additional protection will not be
available in the event of another rear-end collision. You can recognize when NECK-PRO head
restraints have been triggered by the fact that
they have moved forwards and can no longer
be adjusted.
Mercedes-Benz recommends that you have

Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither reduce the risk of an accident nor
override the laws of physics. Driving safety
systems are merely aids designed to assist
driving.
You are responsible for maintaining the distance to the vehicle in front, for vehicle speed,
for braking in good time, and for staying in
lane. Always adapt your driving style to suit
the prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
The driving safety systems described only
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 293).
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 when the engine is running.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions. ABS works on slippery surfaces, even
when you only brake gently.
Important safety notes
i
Observe the "Important safety notes" sec-
tion (Y page 60).
G
WARNING
If ABS is malfunctioning, the wheels could
lock when braking. The steerability and
braking characteristics would be severely
affected. 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 236) and
display messages which may be shown in the
instrument cluster (Y page 206).
Brakes
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.
60
Driving safety systems
Safety
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
i
Observe the "Important safety notes" sec-
tion (Y page 60).
G
WARNING
If BAS is malfunctioning, the braking distance in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking
X
Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
Brake Assist with cross-traffic function
General information
Brake Assist with cross-traffic function can
help you to minimize the risk of a collision with
a vehicle or a pedestrian and reduce the
effects of such a collision. If Brake Assist with
cross-traffic function detects a danger of collision, you are assisted when braking.
i
Observe the "Important safety notes" sec-
tion (Y page 60).
Brake Assist with cross-traffic function is only
available in vehicles with the Driving Assistance package.
For Brake Assist with cross-traffic function to
assist you when driving, the radar sensor system and the camera system must be operational.
The sensor system and camera system help
Brake Assist with cross-traffic function detect
obstacles:
R
that are in the path of your vehicle for an
extended period of time
R
that cross the path of your vehicle
In addition, pedestrians in the path of your
vehicle can be detected.
Brake Assist with cross-traffic function detects
pedestrians using typical characteristics such
as body contours and the posture of a person
standing upright.
If the radar sensor system or the camera system is malfunctioning, Brake Assist with crosstraffic function is restricted or no longer available. The brake system is still available with
complete brake boosting effect and BAS.
i
Observe the restrictions described in the
"Important safety notes" section
(Y page 61).

impaired if:
R
there is dirt on the sensors or anything else
covering the sensors
R
there is interference by other radar sources
R
there are strong radar reflections, for example in parking garages
R
a narrow vehicle is traveling in front, e.g. a
motorbike
R
a vehicle is traveling in front on a different
line
R

Recognition by the camera system is also
impaired in the event of:
R
dirt on the camera or if the camera is covered
R
glare on the camera system, e.g. from the
sun being low in the sky
R
darkness
R
or if:
-
pedestrians move quickly, e.g. into the
path of the vehicle
-
the camera system no longer recognizes a
pedestrian as a person due to special
clothing or other objects
-
a pedestrian is concealed by other
objects
-
the typical outline of a person is not distinguishable from the background
Following damage to the front end of the vehicle, have the configuration and operation of
the radar sensors 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.
Following damage to the windshield, have the
configuration and operation of the camera system checked at a qualified specialist workshop.
Function
To avoid a collision, Brake Assist with crosstraffic function calculates the brake force necessary if:
R
you approach an obstacle, and
R
Brake Assist with cross-traffic function has
detected a risk of collision
When driving at a speed under 20 mph
(30 km/h): if you depress the brake pedal,
Brake Assist with cross-traffic function is activated. The increase in brake pressure will be
carried out at the last possible moment.
When driving at a speed above 20 mph
(30 km/h): if you depress the brake pedal
sharply, Brake Assist with cross-traffic function automatically increases the brake pressure to a degree suited to the traffic situation.
Brake Assist with cross-traffic function provides braking assistance in hazardous situations with vehicles in front within a speed
range between 4 mph (7 km/h) and 155 mph
(250 km/h).
62
Driving safety systems
Safety
Up to a speed of approximately 44 mph
(70 km/h), Brake Assist with cross-traffic
function may react to:
R
stationary objects in the path of your vehicle, e.g. stopped or parked vehicles
R
pedestrians in the path of your vehicle
R
obstacles crossing your path which move in
the detection range of the sensors and are
detected
i
If Brake Assist with cross-traffic function
requires a particularly high braking force,
preventative passenger protection measures
(PRE-SAFE®) are activated at the same time
(Y page 55).
X

there is no longer a risk of collision
R
no obstacle is detected in front of your vehicle
R
you depress the accelerator pedal
R
you activate kickdown
Active Brake Assist
General information
i
Observe the "Important safety notes" section (Y page 60).
Active Brake Assist consists of a distance
warning function with an autonomous braking
function and Adaptive Brake Assist.
Active Brake Assist can help you to minimize
the risk of a collision with the vehicle in front
or reduce the effects of such a collision.
If Active Brake Assist detects that there is a
risk of collision, you will be warned visually
and acoustically. If you do not react to the visual collision warning or the warning tone,
autonomous braking can be initiated in critical
situations. If you apply the brake yourself in a
critical situation, Adaptive Brake Assist of the
Active Brake Assist system supports you.
Important safety notes
In particular, the detection of obstacles can be
impaired if:
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 is traveling in front, e.g. a
motorbike
R
a vehicle is traveling in front on a different
line
R
you are driving a new vehicle or servicing on
the Active Brake Assist system has just
been carried out
Observe the important safety notes in the
"Breaking-in notes" section (Y page 125).
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.
Activating/deactivating
Active Brake Assist is automatically active
after switching on the ignition.
You can activate or deactivate Active Brake
Assist using the on-board computer
(Y page 198). When deactivated, the distance
warning function and the autonomous braking
function are also deactivated.
If Active Brake Assist is deactivated, the æ
symbol appears in the assistance graphic display.
Distance warning function
General information
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.

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
Starting at a speed of approximately 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.
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 approximately 44 mph
(70 km/h), the distance warning function can
also react to stationary obstacles, such as
stopped or parked vehicles.
Autonomous braking function
If the driver does not react to the distance
warning signal in a critical situation, Active
Brake Assist can assist with the autonomous
braking function.
If the autonomous braking function requires a
particularly high braking force, preventative
passenger protection measures (PRE-SAFE®)
are activated simultaneously.
The autonomous braking function is available
in the following speed ranges:
R
4 - 65 mph (7 - 105 km/h) for moving
objects
R
4 - 31 mph (7 - 50 km/h) for stationary
objects
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause the autonomous braking function to intervene.
If the autonomous braking function requires a
particularly high braking force, preventative
passenger protection measures (PRE-SAFE®)
are activated simultaneously (Y page 55).
Adaptive Brake Assist
General information
i
Observe the "Important safety notes" sec-
tion (Y page 60).
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.
If Adaptive Brake Assist detects a risk of collision with the vehicle in front, it calculates the
braking force necessary to avoid a collision. If
you apply the brakes forcefully, Adaptive
Brake Assist will automatically increase the
braking force to a level suitable for the traffic
conditions.
64
Driving safety systems
Safety
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.
Up to a speed of approximately 155 mph
(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.
Up to a speed of approximately 44 mph
(70 km/h), Adaptive Brake Assist reacts to
stationary obstacles.
If Adaptive Brake Assist demands particularly
high braking force, preventative passenger
protection measures (PRE-SAFE®) are activated simultaneously (Y page 55).

i
Observe the "Important safety notes" sec-
tion (Y page 60).
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 engine 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 (Electronic Traction System)
i
Observe the "Important safety notes" sec-
tion (Y page 60).
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 addition, more drive torque is transferred to the
wheel or wheels with traction.
ETS remains active when you deactivate ESP®.
i
Mercedes-AMG vehicles: your vehicle
may be equipped with 20-inch tires on the
rear axle. After changing to 19 inch wheels,
ETS may intervene noticeably earlier during
the first few kilometers. After approximately
10 km ETS will function as usual again.
Information on the dimensions and types of
wheels and tires for your vehicle can be
found in the "Wheel/tire combinations" section (Y page 318).

"Important safety notes" section
(Y page 70).
Important safety notes
G
WARNING
Active Brake Assist with cross-traffic function will initially brake your vehicle by a partial application of the brakes if a danger of
collision is detected. There may be a collision unless you brake yourself. Even after
subsequent full application of the brakes a
collision cannot always be avoided, particularly when approaching at too high a speed.
There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action, provided it is safe to do
so.
If you partially apply the brakes, the vehicle is
braked with up to 50% of the full braking force.
G
WARNING
Active Brake Assist with cross-traffic function cannot always clearly identify objects
and complex traffic situations.
In such cases, Active Brake Assist with
cross-traffic function might:
R
give an unnecessary warning and then
brake the vehicle
R
neither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be prepared to brake, especially if Active Brake Assist with cross-traffic
function alerts you. Terminate the intervention in a non-critical driving situation.
G
WARNING
Active Brake Assist with cross-traffic function cannot always clearly identify people,
particularly if they are moving. Active Brake
Assist with cross-traffic function cannot
70
Driving safety systems
Safety
intervene in these cases. There is a risk of
an accident.
Always pay particular attention to the traffic
situation and be prepared to brake, especially if Active Brake Assist with cross-traffic
function alerts you.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a collision, you must apply the brakes yourself.
G
WARNING
Active Brake Assist with cross-traffic function does not react:
R
to small people, e.g. children
R
to animals
R
to oncoming vehicles
R
when cornering
As a result, Active Brake Assist with crosstraffic function may not warn you or engage
in all critical situations. There is a risk of an
accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In the event of snowfall or heavy rain, the recognition can be impaired.

impaired if:
R
there is dirt on the sensors or anything else
covering the sensors
R
there is interference by other radar sources
R
there are strong radar reflections, for example in parking garages
R
a narrow vehicle is traveling in front, e.g. a
motorbike
R
a vehicle is traveling in front on a different
line
Recognition by the camera system is also
impaired in the event of:
R
dirt on the camera or if the camera is covered
R
glare on the camera system, e.g. from the
sun being low in the sky
R
darkness
R
or if:
-
pedestrians move quickly, e.g. into the
path of the vehicle
-
the camera system no longer recognizes a
pedestrian as a person due to special
clothing or other objects
-
a pedestrian is concealed by other
objects
-
the typical outline of a pedestrian is not
distinguishable from the background
Following damage to the front end of the vehicle, have the configuration and operation of
the radar sensors 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.
Following damage to the windshield, have the
configuration and operation of the camera system checked at a qualified specialist workshop.
