Protection of the environment
General notes
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.
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 note
H
Have a defective high-voltage battery
disposed of in an environmentallyresponsible 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
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
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
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
Page 25
Introduction
23
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.
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 safetyrelevant 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
Mercedes-Benz parts (Y page 422).

Operating safety
Important safety notes
WARNING
G
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.
WARNING
G
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
WARNING
G
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 off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
WARNING
G
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.
Z
Page 28
Introduction
26
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 any changes to the vehicle
electronics, the general operating permit is
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.

Limited Warranty
!
Follow the instructions in this manual
about the proper operation of your vehicle
as well as about possible vehicle damage.
Damage to your vehicle that arises from
culpable contraventions against these
instructions is not covered either by the
Mercedes-Benz Limited Warranty or by the
New or Used-Vehicle Warranty.
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
Page 31
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 preempted. 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.

SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS warning lamp
WARNING
G
If SRS is malfunctioning, child restraint
system components may be triggered
unintentionally or might not be triggered at all
in the event of an accident with a high rate of
vehicle deceleration. There is an increased
risk of injury, possibly even fatal.
Have SRS checked and repaired immediately
at a qualified specialist workshop.
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS 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 engine is started.
The SRS components are in operational
readiness when the 6 SRS indicator lamp
goes out while the engine is running.
There is a malfunction if:
R
the 6 SRS warning lamp does not light
up when the ignition is switched on
R
the engine is running and the 6 SRS
warning lamp does not go out after a few
seconds
R
the engine is running and the 6 SRS

Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags
WARNING
G
R
Damaged seat belts or seat belts that have
been subjected to stress in an accident
must be replaced. Their anchoring points
must also be checked. Only use seat belts
installed or supplied by an authorized
Mercedes-Benz Center.
R
Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling and regard for the
environment. Check your national disposal
guidelines. California residents, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
R
Air bags and ETDs are designed to function
on a one-time-only basis. An air bag or ETD
that has deployed must be replaced. PRESAFE®has electrically operated reversible
belt tensioners in addition to the
pyrotechnic ETDs.
R
Do not pass seat belts over sharp edges.
They could tear.
R
Do not make any modification that could
change the effectiveness of the seat belts.
R
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
R
No modifications of any kind may be made
to any components or wiring of the SRS.
R
Do not change or remove any component

an air bag has inflated. Do not touch them.
R
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
R
Improper repair work on the SRS creates a
risk of rendering the SRS inoperative or
causing unintended air bag deployment.
Work on the SRS must therefore only be
performed by qualified technicians.
Contact an authorized Mercedes-Benz
Center.
R
For your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These instructions are available
from any authorized Mercedes-Benz
Center.
R
Given the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, Mercedes-Benz
strongly recommends that you inform the
subsequent owner that the vehicle is
equipped with SRS. Also, refer them to the
applicable section in the Operator's Manual.
Air bags
Important safety notes
The air bag installation locations are
identified by the AIR BAG symbol.
WARNING
G
Using unsuitable seat covers could restrict or
even 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
function of the air bag deactivation system
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.
You should only use seat covers that have
been approved for your vehicle by MercedesBenz. The seat covers must have a special
tear seam for side impact air bags. Otherwise,
the side impact air bags cannot deploy
correctly and therefore cannot provide the
intended protection in the event of an
accident.
WARNING
G
The air bag parts are hot after the airbag has
been deployed. There is a risk of injury.
Do not touch the air bag parts. Have the
deployed air bags replaced at a qualified
specialist workshop as soon as possible.
Page 49
Occupant safety
47
WARNING
G
Air bags are designed to reduce the incidence
of injuries and fatalities in certain situations:
R
frontal impacts (driver's and frontpassenger front air bags and driver's knee
bag)
R
side impacts (side impact air bags and
window curtain air bags)
R
rollover (window curtain air bags)
However, no system available today can
completely eliminate injuries and fatalities.
When the air bags are deployed, a small
amount of powder is released. The powder
generally does not constitute a health hazard
and does not indicate that there is a fire in the
vehicle. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. If you
have any breathing difficulty but cannot get
out of the vehicle after the air bag inflates,
then get fresh air by opening a window or
door.
WARNING
G
In order to reduce the potential danger of
injuries caused during the deployment of the
front air bags, the driver and front passenger
must always be correctly seated and wear
their seat belts.
For maximum protection in the event of a
collision, you must always be in the normal
seat position with your back against the
backrest. Fasten your seat belt and make sure
that it is correctly positioned on your body.
As the air bag inflates with considerable
speed and force, a proper seating position
and correct positioning of the hands on the
steering wheel will help to keep you at a safe
distance from the air bag. Occupants who are
not wearing their seat belt, are not seated
properly or are too close to the air bag can be
seriously injured or killed by an air bag, as it
inflates with great force instantaneously:
R
sit with the seat belt fastened correctly and
in a position that is as upright as possible
with your back against the backrest.
R
move the driver's seat as far back as
possible, still permitting proper operation
of vehicle controls. The distance from the
center of the driver's chest to the center of
the air bag cover on the steering wheel
must be at least 10 inches (25 cm). You
should be able to accomplish this by
adjusting the seat and steering wheel. If
you have any difficulties, please contact an
authorized Mercedes-Benz Center.
R
do not lean your head or chest close to the
steering wheel or dashboard.
R
only hold the steering wheel on the outside.
Placing hands and arms inside the rim can
increase the risk and potential severity of
hand/arm injury if the driver front air bag
inflates.
R
adjust the front-passenger seat as far back
as possible from the dashboard when the
seat is occupied.
R
occupants, especially children, should
never place their bodies or lean their heads
in the area of the door where the side
impact air bag inflates. This could result in
serious or fatal injuries should the side
impact air bag be deployed. Always sit as
upright as possible, wear the seat belt
properly and use an appropriately sized
infant restraint, toddler restraint or booster
seat recommended for the size and weight
of the child.
Failure to follow these instructions can result
in severe injuries to you or other occupants.

If you sell your vehicle, it is important that you
make the buyer aware of this safety
information. Be sure to give the buyer this
Operator's Manual.
i
After an air bag has been deployed, have
the vehicle towed to the nearest qualified
specialist workshop, even if your vehicle is
ready to drive.
If the air bags are deployed, you will hear a
bang, and a small amount of powder may also
be released. Only in rare cases will the bang
Safety
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicate that there
is a fire in the vehicle. The dust might cause
some temporary breathing difficulty for
people with asthma or other breathing
trouble. To avoid this, you may wish to get out
of the vehicle as soon as it is safe to do so.
You can also open the window to allow fresh
air to enter the vehicle interior. The 6 SRS
warning lamp lights up.
The air bags are deployed if the air bag control
unit detects the need for deployment. Only in
the event of such a situation will the air bags
provide their supplemental protection.
If the driver and front passenger do not wear
their seat belts, it is not possible for the air
bags to provide their supplemental
protection.
In the event of other types of impacts and
impacts below air bag deployment
thresholds, the air bags will not deploy. The
driver and passenger will then be protected
to the extent possible by a properly fastened
seat belt. A properly fastened seat belt is also
needed to provide the best possible
protection in a rollover.
Air bags provide additional protection; they
are not, however, a substitute for seat belts.
All vehicle occupants must fasten their seat
belts regardless of whether your vehicle is
equipped with air bags or not.
It is important for your safety and that of your
passenger to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air
bags continue to perform their protective
function for the vehicle occupants in the
event of a crash.
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.
The front air bags increase protection for the
driver's and front passenger's head and
chest.
They are deployed:
R
at the start of an accident with a high rate
of vehicle acceleration or deceleration in a
longitudinal direction
R
if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R
independently of other air bags in the
vehicle
The release time of the front air bags is
dependent upon the use of the seat belt.
If the vehicle rolls over, the front air bags are
generally not deployed.
Your vehicle has adaptive, two-stage front air
bags. In the event of a collision, the air bag
control unit evaluates the vehicle
deceleration. In the first deployment stage,
the front air bag is filled with enough
propellant gas to reduce the risk of injuries.
The front air bag is fully deployed if a second

deployment threshold is exceeded within a
few milliseconds.
The deployment of the front-passenger front
air bag is also influenced by the weight
category of the front passenger, which is
determined by the Occupant Classification
System (OCS) (Y page 51).
The lighter the passenger-side occupant, the
higher the vehicle deceleration rate required
(predicted at the start of the impact) for
second-stage inflation of the front-passenger
front air bag. In the second stage, the front
air bags are inflated with the maximum
amount of propellant gas available.
The front air bags are not deployed in
situations where a low impact severity is
predicted. You will then be protected by the
fastened seat belt.
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
R
the PASSENGER AIR BAG OFF indicator
lamp on the center console is not lit
(Y page 51)
R
the air bag control unit predicts a high
impact severity
Driver's knee bag
i
Observe the "Important safety notes"
section (Y page 46)
always deployed along with the driver's front
air bag. The driver's knee bag is designed to
operate together with the front air bags in
frontal impacts if certain thresholds are
exceeded. The driver's knee bag operates
best in conjunction with correctly positioned
and fastened seat belts.
The driver's knee bag increases protection of
the driver against:
R
knee injuries
R
thigh injuries
R
lower leg injuries
Side impact air bags
WARNING
G
Using unsuitable seat covers could restrict or
even 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
function of the air bag deactivation system
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.
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 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.

the side impact air bags cannot deploy
correctly and therefore cannot provide the
intended protection in the event of an
accident.
Safety
Front side impact air bags : and rear side
impact air bags ; deploy next to the outer
seat cushions.
When deployed, the side impact air bags offer
additional protection for the thorax of the
vehicle occupants on the side of the vehicle
on which the impact occurs. However, they
do not protect the:
R
head
R
neck
R
arms
The side impact air bags are deployed:
R
on the side on which an impact occurs
R
at the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
R
independently of the use of the seat belt
R
independently of the front air bags
R
independently of the ETDs
If the vehicle rolls over, the side impact air
bags are generally not deployed. Side impact
air bags are deployed if the system detects
high vehicle deceleration or acceleration in a
lateral direction and determines that side
impact air bag deployment can offer
additional protection to that provided by the
seat belt.
Side impact air bags will not deploy in side
impacts which do not exceed the system's
preset deployment thresholds for lateral
acceleration/deceleration. You will then be
protected by the fastened seat belt.
The side impact air bag on the frontpassenger side will deploy if the frontpassenger seat belt is fastened, regardless of
whether the front-passenger seat is occupied
or not.
Window curtain air bags
Window curtain air bags : enhance the level
of protection for the head, but not chest or
arms, of the vehicle occupants on the side of
the vehicle on which the impact occurs.
The window curtain air bags are integrated
into the side of the roof frame and deploy in
the area from the A-pillar to the C-pillar.
Window curtain air bags are deployed:
R
at the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
R
on the side on which an impact occurs
R
on the driver's and the front passenger's
side if the vehicle rolls over and the system
determines that window curtain air bag
deployment can offer additional protection

R
independently of the use of the seat belt
R
regardless of whether the front-passenger
seat is occupied
R

Window curtain air bags will not deploy in the
event of impacts which do not exceed the
system's preset deployment thresholds for
vehicle acceleration/deceleration. You will
then be protected by the fastened seat belt.
Cushion air bags
i
Observe the "Important safety notes"
section (Y page 46).
i
When installing a child restraint system,
please observe the "Child restraint
systems" section (Y page 63).
WARNING
G
If a child restraint system is installed and the
seat backrest is reclined too far backwards,
the cushion air bag may deploy by mistake in
the event of an accident. There is an increased
risk of injury.
When using a child restraint system, always
ensure that the seat is correctly adjusted and
that the backrest is almost vertical.
The rear reclining seat is equipped with a
cushion air bag. If the seat backrest is
reclined, the cushion air bag can provide
additional occupant protection in the event of
a frontal collision. When triggered, the
cushion air bag deploys under the seat
cushion. This helps prevent the occupant
from slipping off the seat cushion.
Occupant Classification System
(OCS)
Method of operation
WARNING
G
If the 45 indicator lamp illuminates
when an adult or someone larger than a small
individual is in the front passenger seat, have
the front passenger reposition himself or
herself in the seat until the 45
indicator lamp goes out.
In the event of a collision, the air bag control
unit will not allow front passenger front air bag
deployment when the OCS has classified the
front passenger seat occupant as weighing as
much as or less than a typical 12-month-old
child in a standard child restraint or if the front
passenger seat is classified as being empty.
When the OCS senses that the front
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 45 indicator lamp will
illuminate when the engine is started and
remain illuminated. This indicates that the
front passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat is classified as being empty,
the 45 indicator lamp will illuminate
when the engine is started and remain
illuminated. This indicates that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat occupant is classified as
being heavier than the weight of a typical 12month-old child seated in a standard child
restraint or as being a small individual (such
as a young teenager or a small adult), the
45 indicator lamp will illuminate for
approximately 6 seconds when the engine is
started. Depending on occupant weight
sensor readings from the seat, it will then
remain illuminated or go out. With the
45 indicator lamp illuminated, the
front passenger front air bag is deactivated.
With the 45 indicator lamp out, the
front passenger front air bag is activated.
When the OCS senses that the front
passenger seat occupant is classified as an
adult or someone larger than a small
individual, the 45 indicator lamp will
illuminate for approximately six seconds
when the engine is started and then go out.
This indicates that the front passenger front
air bag is activated.
If the 45 indicator lamp is illuminated,
the front passenger front air bag is
deactivated and will not be deployed.

WARNING
G
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seats whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriate infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and Top Tether strap, or lower anchors
and Top Tether strap, fully in accordance with
the child seat manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the frontpassenger seat:
R
Your vehicle is equipped with air bag
technology designed to deactivate the
front-passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the front-passenger seat.
R
A child in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to eliminate
this risk completely is never to place a child
in a rear-facing child restraint in the frontpassenger seat. We therefore strongly
recommend that you always place a child
in a rear-facing child restraint on the rear
seat.
R
If you install a rear-facing child restraint on
the front-passenger seat, make sure the
45 indicator lamp is illuminated,
indicating that the front-passenger front air
bag is deactivated. Should the 45
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the
45 indicator lamp while driving to
make sure that the 45 indicator
lamp is illuminated. If the 45
indicator lamp goes out or remains out, do
not transport a child on the front-passenger
seat until the system has been repaired.
A child in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates.
Page 55
R
If you place a child in a forward-facing child
restraint on the front-passenger seat:
-
move the seat as far back as possible
-
use the proper child restraint
recommended for the age, size and
weight of the child
-
secure child restraint with the vehicle's
seat belt according to the child seat
manufacturer's instructions
R
For children larger than the typical 12month-old child, the front-passenger front
air bag may or may not be activated.
WARNING
G
If the red 6 SRS warning lamp in the
instrument cluster and the 45
indicator lamp light up simultaneously, the
OCS is malfunctioning. The front passenger
front air bag will be deactivated in this case.
Have the system checked by qualified
technicians as soon as possible. Contact an
authorized Mercedes-Benz Center.
Only have the seat repaired or replaced at an
authorized Mercedes-Benz Center.
In order to ensure proper operation of the air
bag system and OCS:
R
Sit with the seat belt properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
R
When seated, a passenger should not
position him/herself in such a way as to
cause the passenger's weight to be lifted
from the seat cushion as this may result in
the OCS being unable to correctly

PRE-SAFE®(anticipatory occupant
protection system)
Introduction
PRE-SAFE®takes preemptive measures to
protect occupants in certain hazardous
situations.
Safety
Important safety notes
!
Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
Despite your vehicle being equipped with the
PRE-SAFE®system, the possibility of
personal injuries occurring as a result of an
accident cannot be eliminated.
Always adapt your driving style to suit the
prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
Function
PRE-SAFE®intervenes:
R
in emergency braking situations, e.g. when
BAS is activated.
R
in critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely.
R
vehicles with the Driving Assistance
package: when a driver assistance system
intervenes powerfully or the radar sensor
system detects an imminent danger of
collision in certain situations
PRE-SAFE®takes the following measures
depending on the hazardous situation
detected:
R
the front seat belts are pre-tensioned.
R
if the vehicle skids, the panorama roof with
power tilt/sliding panel and the side
windows are closed so that only a small gap
remains.
R
the front-passenger seat is adjusted if it is
in an unfavorable position.
R
vehicles with electrically adjustable
rear seats: the outer rear seats are
adjusted if they are in an unfavorable
position.
R
vehicles with a multicontour seat: the
air pressure in the side bolsters of the
backrest is increased.
R
vehicles with seat belt extenders: the
seat belts of the outer rear seats are pretensioned.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE®slackens
the belt pre-tensioning. On vehicles with
multicontour seats, the air pressure in the
side bolsters is reduced again. All settings
made by PRE-SAFE®can then be reversed.
If the seat belts are not released:
X
When the vehicle is stationary, move the
backrest or seat back slightly.
The seat belt pre-tensioning is reduced and
the locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE®convenience function. More
information about seat-belt adjustment can
be found under "Seat-belt adjustment"
(Y page 60).
More information about PRE-SAFE®PLUS
(Y page 56).
PRE-SAFE®PLUS (anticipatory
occupant protection system PLUS)
General information
PRE-SAFE®PLUS is only available in vehicles
with the Driving Assistance package.
Using the radar sensor system, PRE-SAFE
®
PLUS is able to detect that a head-on or rearend collision is imminent. In certain
hazardous situations, PRE-SAFE®PLUS takes
pre-emptive measures to protect the vehicle
occupants.
Page 59
Occupant safety
57
Important safety notes
The intervention of PRE-SAFE®PLUS cannot
prevent an imminent collision.
The driver is not warned when PRE-SAFE
®
PLUS intervenes.
PRE-SAFE®PLUS does not intervene:
R
if the vehicle is backing up
R
when the vehicle is towing a trailer and
there is a risk of a rear-end collision
PRE-SAFE®PLUS does not perform braking
actions while the vehicle is in motion or when
Parking Guidance is active.
Function
PRE-SAFE®PLUS intervenes in certain
situations if the radar sensor system detects
an imminent head-on or rear-end collision.
PRE-SAFE®PLUS takes the following
measures depending on the hazardous
situation detected:
R
If the radar sensor system detects that a
head-on collision is imminent, the seat
belts are pre-tensioned.
R
If the radar sensor system detects that a
rear-end collision is imminent:
-
the brake pressure is increased if the
driver applies the brakes when the
vehicle is stationary.
-
the seat belts are pre-tensioned.
The PRE-SAFE®PLUS braking application is
canceled in the following situations:
R
if the accelerator pedal is depressed when
a gear is engaged
R
if the risk of a collision passes or is no
longer detected
R
if DISTRONIC PLUS indicates an intention
to pull away
If the hazardous situation passes without
resulting in an accident, the original settings
are restored.
Automatic measures after an
accident
Immediately after an accident, the following
measures are implemented, depending on
the type and severity of the impact:

Seat belts
Important safety notes
WARNING
G
Objects next to the front seat that block the
belt buckle or the moving belt anchorage on
the front seat impair the function of the
Emergency Tensioning Devices. The
Emergency Tensioning Devices may not
function as intended and the seat belt may no
longer provide the intended protection. This
poses an increased risk of injury or even fatal
injury.
Before starting the journey, make sure that
there are no objects around the belt buckle or
between the front seat and door.
WARNING
G
The seat belt does not offer the intended level
of protection if the backrest is not in the
upright 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 make sure that the seat
is in the upright position.
WARNING
G
Seat belts cannot protect as intended, if:
Safety
R
they are damaged, extremely dirty,
bleached or dyed
R
the seat belt buckle is damaged or
extremely dirty
R
the Emergency Tensioning Devices or the
belt anchorage has been modified.
Damage caused to seat belts in an accident
may not be visible, e.g. by splinters of glass.
Modified or damaged seat belts can tear or
fail, for example in the event of an accident.
Modified Emergency Tensioning Devices may
be deployed unintentionally or fail to be
deployed when required. There is an
increased risk of injury, possibly even fatal.
Never modify seat belts, Emergency
Tensioning Devices, seat belt anchorages and
inertia reels. Ensure that seat belts are not
damaged or worn and are clean.
Only use seat belts that have been approved
for your vehicle by Mercedes-Benz.
The use of seat belts and infant and child
restraint systems is required by law in:
R
all 50 states
R
the U.S. territories
R
the District of Columbia
R
all Canadian provinces
Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey.
i
See "Children in the vehicle"
(Y page 63) for further information on
infants and children traveling in the vehicle
as well as on child restraint systems.
Correct use of the seat belts
WARNING
G
USE SEAT BELTS PROPERLY
R
Seat belts can only work when used
properly. Never wear seat belts in any other
way than as described in this section, as
that could result in serious injuries in the
event of an accident.
R
Each occupant should wear their seat belt
at all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver front air bag, front-passenger
front air bag, side impact air bags, window
curtain air bags for the side windows),
Emergency Tensioning Devices, seat belt
force limiters, and front seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air bags
and ETDs) and side (side impact air bags,
window curtain air bags, and ETDs) impacts
which exceed preset deployment
thresholds and in certain rollovers (window
curtain air bags and ETDs).
R
Never wear the shoulder belt under your
arm, across your neck or off your shoulder.
In a frontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder. It should not
touch the neck. Never pass the shoulder
portion of the seat belt under your arm. For
this purpose, you can adjust the height of
the seat belt outlet.
R
Position the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your
Page 61
Occupant safety
59
abdomen, it could cause serious injuries in
a crash.
R
Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys etc., as
these might cause injuries.
R
Make sure the seat belt is always routed
snugly. Take special care of this when
wearing loose clothing.
R
Never use a seat belt for more than one
person at a time. Do not fasten a seat belt
around a person and another person or
other objects at the same time.
R
Seat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distribute impact forces.
The twisted seat belt against your body
could cause injuries.
R
Pregnant women should also always use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible on
the hips to avoid any possible pressure on
the abdomen.
R
Place the seat backrest in a position that is
as upright as possible.
R
Check your seat belt during travel to make
sure it is properly positioned.
R
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
R
When using a seat belt to secure infant
restraints, toddler restraints, or children in
booster seats, always follow the child seat
manufacturer's instructions.
WARNING
G
Do not pass seat belts over sharp edges. They
could tear.
Do not allow the seat belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the seat belt.
Never attempt to make modifications to seat
belts. This could impair the effectiveness of
the seat belts.
Fastening seat belts
WARNING
G
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriately sized
child restraint system or booster seat
recommended for the size and weight of the
child. For additional information, see the
"Children in the vehicle" section.
A child's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.

Belt warning for the driver and front
passenger
Regardless of whether the driver's and frontpassenger seat belts have already been
fastened, the 7 seat belt warning lamp
lights up for six seconds each time the engine
is started. It then goes out if the driver and
the front passenger have already fastened
their seat belts.
If the driver's seat belt is not fastened when
the engine is started, an additional warning
tone will sound. This warning tone stops after
a maximum of six seconds or once the
driver's seat belt is fastened.
If after six seconds, the driver or front
passenger have not fastened their seat belts
and the doors are closed:
R
the 7 seat belt warning lamp remains lit
as long as the driver's or front-passenger's
seat belt is not fastened
and
R
if a vehicle speed of 15 mph (25 km/h) is
exceeded, the 7 seat belt warning lamp
begins to flash. A warning tone also sounds
with increasing intensity for a maximum of
60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver/front passenger unfasten their
seat belt while the vehicle is in motion, the
7 seat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases even if the driver or
front-passenger seat belt has still not been
fastened after 60 seconds. The 7 seat belt
warning lamp stops flashing but remains
illuminated.
After the vehicle comes to a standstill, the
warning tone is reactivated and the 7 seat

Emergency Tensioning Devices, seat
belt force limiters
WARNING
G
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer
operational and are unable to perform their
intended protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency
Tensioning Devices which have been
triggered immediately replaced at a qualified
specialist workshop.
!
If the front-passenger seat is not
occupied, do not engage the seat belt
tongue in the buckle on the frontpassenger seat. Otherwise, in the event of
an accident the different stages of the
Emergency Tensioning Devices could be
triggered.
i
An electric motor is used by PRE-SAFE
to trigger the tightening of the seat belt in
hazardous situations. This procedure is
reversible.
The front seat belts and the outer seat belts
in the rear are equipped with Emergency
Tensioning Devices and seat belt force
limiters.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
If the seat belt is also equipped with a seat
belt force limiter and this is triggered, the
force exerted by the seat belt on the vehicle
occupant is reduced.
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 results in the force exerted on the
occupant being distributed over a greater
area.
The ETDs can only be activated when:
R
the ignition is switched on
R
the restraint systems are operational; see
"SRS warning lamp" (Y page 45)
R
the front-passenger seat is occupied and
the belt tongue is engaged in the buckle on
the front-passenger side
R
the belt tongue is engaged in the buckle on
each of the three-point seat belts in front
The ETDs on the outside seats in the rear
compartment are triggered independently of
the lock status of the seat belts.
The various stages of the Emergency
Tensioning Devices are triggered depending
on the type and severity of an accident:
R
in the event of a head-on or rear-end
collision if the vehicle decelerates or
®
accelerates rapidly in a longitudinal
direction during the initial stages of the
impact.
R
in the event of a side impact if the vehicle
decelerates or accelerates rapidly in a
lateral direction on the side opposite to the
impact.
R
in certain situations where the vehicle rolls
over if the system determines that it can
provide additional protection.
Page 65
Children in the vehicle
63
If the ETDs are deployed, you will hear a bang,
and a small amount of powder may also be
released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicate that there
is a fire in the vehicle. The dust might cause
some temporary breathing difficulty for
people with asthma or other breathing
trouble. To avoid this, you may wish to get out
of the vehicle as soon as it is safe to do so.
You can also open the window to allow fresh
air to enter the vehicle interior. The 6 SRS
warning lamp lights up.
Belt bags
i
Observe the "Important safety notes"
section (Y page 46).
WARNING
G
In an accident, the belt bag may damage a
non-approved child restraint system. As a
result, the child restraint system may not be
able to provide the intended level of
protection. There is an increased risk of
injury.
For safety reasons, we recommend that you
only use a child restraint system which has
been tested and approved by Mercedes-Benz
in combination with a belt bag.
i
Further information on child restraint
systems (Y page 63).
The rear seat belts are equipped with belt
bags :. These are triggered depending on
the type and severity of the accident. When
triggered, the belt bags open, increasing the
protected area of the occupants' ribcages.
Children in the vehicle
Child restraint systems
Important safety notes
WARNING
G
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and top tether strap, or lower anchors and
top tether strap, fully in accordance with the
child seat manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the front
passenger seat:
R
Your vehicle is equipped with air bag
technology designed to deactivate the front
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the front passenger seat.
R
For children larger than the typical
12-month-old child, the front passenger
Safety

front air bag may or may not be activated.
Always make sure the 45indicator
lamp is illuminated, indicating that the front
passenger front air bag is deactivated.
R
A child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates in a collision which
Safety
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to
completely eliminate this risk is to never
place a child in a rear-facing child restraint
in the front seat. We therefore strongly
recommend that you always place a child
in a rear-facing child restraint in a backseat.
R
If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure the 45indicator
lamp is illuminated, indicating that the front
passenger front air bag is deactivated.
Should the 45indicator lamp not
illuminate or go out while the restraint is
installed, please check installation.
Periodically check the 45indicator
lamp while driving to make sure the 4
5 indicator lamp is illuminated. If the
45indicator lamp goes out or
remains out, do not transport a child on the
front passenger seat until the system has
been repaired.
A child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates.
R
If you have to place a child in a forwardfacing child restraint on the front passenger
seat, move the seat as far back as possible,
use the proper child restraint
recommended for the age, size and weight
of the child, and secure child restraint with
the vehicle's seat belt according to the
child seat manufacturer's instructions.
WARNING
G
If the child restraint system is installed
incorrectly on a suitable seat, it cannot
protect as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There
is an increased risk of injury, possibly even
fatal.
Make sure that you observe the child restraint
system manufacturer's installation
instructions and the notes on use. Please
ensure, that the base of the child restraint
system is always resting completely on the
seat cushion. Never place objects, e.g.
cushions, under or behind the child restraint
system. Only use child restraint systems with
the original cover designed for them. Only
replace damaged covers with genuine covers.
WARNING
G
If the child restraint system is installed
incorrectly or is not secured, it can come
loose in the event of an accident, heavy
braking or a sudden change in direction. The
child restraint system could be thrown about,
striking vehicle occupants. There is an
increased risk of injury, possibly even fatal.
Always install child restraint systems
properly, even if they are not being used.
Make sure that you observe the child restraint
system manufacturer's installation
instructions.
WARNING
G
Child restraint systems or their securing
systems which have been damaged or
subjected to a load in an accident can no
longer protect as intended. The child cannot
then be restrained in the event of an accident,
heavy braking or sudden changes of direction.
There is an increased risk of injury, possibly
even fatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the
securing systems on the child restraint

system checked at a qualified specialist
workshop, before you install a child restraint
system again.
WARNING
G
Infants and small children should never share
a seat belt with another occupant. In the event
of an accident, they could be crushed
between the occupant and seat belt.
A child's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
Children that are too large for a child restraint
must travel in seats using normal seat belts.
Position the shoulder belt across the chest
and shoulder, not the face or neck. A booster
seat may be necessary to achieve proper seat
belt positioning for children over 41 lbs
(18 kg) until they reach a height where a lap/
shoulder belt fits properly without a booster
seat.
When the child restraint is not in use, remove
it from the vehicle or secure it with the seat
belt to prevent the child restraint from
becoming a projectile in the event of an
accident.
WARNING
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
shifting the automatic transmission out of
park position P
R

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.
i
The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Please pay special
attention to the notes on tires,
recommended minimum tire tread depths,
etc. (Y page 384).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
Page 73
Driving safety systems
71
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.
Important safety notes
i
Observe the "Important safety notes"
section (Y page 70).
WARNING
G
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics 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 304) and
display messages which may be shown in the
instrument cluster (Y page 266).
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.
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
i
Observe the "Important safety notes"
section (Y page 70).
WARNING
G
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.

BAS PLUS (Brake Assist System
PLUS) with Cross-Traffic Assist
General information
i
Observe the "Important safety notes"
section (Y page 70).
BAS PLUS is only available on vehicles with
Safety
the Driving Assistance package.
For BAS PLUS to assist you when driving, the
radar sensor system and the camera system
must be operational.
With the help of a sensor system and a
camera system, BAS PLUS can 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.
BAS PLUS detects pedestrians by using
typical characteristics such as the body
contours and posture of a person standing
upright.
If the radar sensor system or the camera
system is malfunctioning, BAS PLUS
functions are 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 72).
BAS PLUS 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
BAS PLUS detects a danger of collision, you
are assisted when braking.
Important safety notes
WARNING
G
BAS PLUS cannot always clearly identify
objects and complex traffic situations.
In such cases, BAS PLUS may:
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
BAS PLUS does not react:
R
to small people, e.g. children
R
to animals
R
to oncoming vehicles
R
when cornering
As a result, BAS PLUS may not intervene 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.
Recognition by the radar sensor system is
also impaired in the event of:
R
dirt on the sensors or anything else
covering the sensors
R
interference by other radar sources
R
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
R
vehicles quickly moving into the radar
sensor system detection range
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
Page 75

73
R
darkness
R
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 low 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, BAS PLUS calculates the
brake force necessary if:
R
you approach an obstacle, and
R
BAS PLUS has detected a risk of collision
When driving at a speed under 20 mph
(30 km/h): if you depress the brake pedal,
BAS PLUS 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, BAS PLUS automatically raises the
brake pressure to a value adapted to the
traffic situation.
BAS PLUS 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).
At speeds of up to approximately 44 mph
(70 km/h), BAS PLUS reacts 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
objects crossing your path
i
If BAS PLUS demands particularly high
braking force, preventative passenger
protection measures (PRE-SAFE®) are
activated simultaneously.
X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes
function as usual again, if:
R
you release the brake pedal.
R
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.
COLLISION PREVENTION ASSIST

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
Safety
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.
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
R
new vehicles or after the COLLISION
PREVENTION ASSIST system has been
serviced
Observe the notes in the section on
breaking-in (Y page 170).
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.
Function
X
To activate/deactivate: activate or
deactivate the distance warning function in
the on-board computer (Y page 261).
If the distance warning function is not
activated, the æ symbol appears 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.
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.
From 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.

Adaptive Brake Assist aids you in braking
during hazardous situations at speeds above
4 mph (7 km/h) and uses the radar sensor
system to evaluate 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.
Should you approach an obstacle and
Adaptive Brake Assist has detected a risk of
collision, Adaptive Brake Assist calculates the
braking force necessary to avoid a rear-end
collision. Should you apply the brakes
vigorously, 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.
The brakes will work normally again if:
R
you release the brake pedal.
R
there is no longer any danger of a collision.
R
no obstacle is detected in front of your
vehicle.
Adaptive Brake Assist is then deactivated.
Up to vehicle speeds of around 155 mph
(250 km/h), adaptive Brake Assist is capable

ESP®(Electronic Stability Program)
Safety
General notes
i
Observe the "Important safety notes"
section (Y page 70).
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/4ETS (Electronic Traction System)
i
Observe the "Important safety notes"
section (Y page 70).
ETS/4ETS traction control is part of ESP®.
Traction control 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.
Traction control remains active, even if you
deactivate ESP®.
Important safety notes
WARNING
G
If ESP®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP®checked at a
qualified specialist workshop.
!
Vehicles with 4MATIC: switch off the
ignition when the electric parking brake is
being tested on a brake dynamometer.
Application of the brakes by ESP®may
otherwise destroy the brake system.
Vehicles without 4MATIC: observe the notes
on ESP®(Y page 377) when towing the
vehicle with a raised rear axle.
ESP®is deactivated if the å warning lamp
in the instrument cluster lights up
continuously when the engine is running.
If the ÷ warning lamp lights up
continuously, ESP®is not available due to a
malfunction.
Observe the information on warning lamps
(Y page 305) and display messages which
may be shown in the instrument cluster
(Y page 266).
®
i
Only use wheels with the recommended
tire sizes. Only then will ESP®function
properly.
Characteristics of ESP
®
General information
If the ÷ ESP warning lamp goes out before
beginning the journey, ESP®is automatically

Crosswind driving assistance
General information
Vehicles with MAGIC BODY CONTROL:
information on stabilizing the vehicle in the
event of crosswind (Y page 213).
Strong crosswinds can cause your vehicle to
deviate from a straight course. The crosswind
driving assistance function integrated into
ESP®significantly reduces these effects.
ESP®intervenes automatically according to
the direction and intensity of the crosswinds
affecting your vehicle.
ESP stabilities the vehicle with braking
interventions to assist you in keeping the
vehicle in the lane.
Crosswind driving assistance is active at
vehicle speeds above 50 mph (80 km/h)
Z

when driving straight ahead or cornering
gently.
Important safety notes
Crosswind driving assistance does not work
if ESP®is deactivated or disabled because of
a malfunction.
Safety
EBD (electronic brake force
distribution)
General information
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.
Important safety notes
i
Observe the "Important safety notes"
section (Y page 70).
WARNING
G
If EBD has malfunctioned, the rear wheels can
still 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 304) as well as
display messages (Y page 269).
PRE-SAFE®Brake
General information
i
Pay attention to the important safety
notes in the "Driving safety systems"
section (Y page 70).
PRE-SAFE®Brake is only available for
vehicles with the Driving Assistance package.
For PRE-SAFE®Brake to assist you when
driving, the radar sensor system and the
camera system must be switched on and be
operational.
With the help of the radar sensor system and
the camera system, PRE-SAFE®Brake can
detect obstacles that are in front of your
vehicle for an extended period of time.
In addition, pedestrians in the path of your
vehicle can be detected.
PRE-SAFE®Brake detects pedestrians using
typical characteristics such as the body
contours and posture of a person standing
upright.
i
Observe the restrictions described in the
"Important safety notes"
section“ (Y page 78).
PRE-SAFE®Brake can help you to minimize
the risk of a collision with a vehicle ahead or
a pedestrian, and reduce the effects of such
a collision. If PRE-SAFE®Brake has detected
a risk of collision, you will be warned visually
and acoustically as well as by automatic
braking.
ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In
addition to the braking function, ADAPTIVE
BRAKE also has the HOLD function
(Y page 212) and hill start assist
(Y page 175).
Important safety notes
WARNING
G
PRE-SAFE®Brake 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.
Page 81
Driving safety systems
79
Always apply the brakes yourself and try to
take evasive action, provided it is safe to do
so.
WARNING
G
PRE-SAFE®Brake cannot always clearly
identify objects and complex traffic
conditions.
In these cases, PRE-SAFE®Brake may:
R
give an unnecessary warning and then
brake the vehicle
R
not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE®Brake warns you. Terminate the
intervention in a non-critical driving situation.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a
collision, you must apply the brakes yourself.
PRE-SAFE®Brake can also brake the vehicle
automatically under the following conditions:
R
the driver and front-passenger have their
seat belts fastened
and
R
the vehicle speed is between
approximately 4 mph (7 km/h) and
124 mph (200 km/h)
At a speed of up to approximately 44 mph
(70 km/h), PRE-SAFE®Brake can also detect:
R
stationary objects in the path of your
vehicle, e.g. stopped or parked vehicles
R
pedestrians in the path of your vehicle
WARNING
G
PRE-SAFE®Brake does not react:
R
to small people, e.g. children
R
to animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
As a result, PRE-SAFE®Brake may neither
give warnings nor intervene 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.
Recognition by the radar sensor system is
also impaired in the event of:
R
dirt on the sensors or anything else
covering the sensors
R
interference by other radar sources
R
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
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
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 low speeds where there is no
visible damage to the front of the vehicle.
