Protecting 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 concerns and recommendations
Wherever the Operator's Manual requires 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

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 relating 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
to the vehicle manufacturer, other parties that
have the special equipment, such as law
enforcement, can read the information by
accessing the vehicle or the EDR.
EDR data may be used in civil and criminal
matters as a tool in accident reconstruction,
accident claims and vehicle safety. Since the
Crash Data Retrieval CDR tool that is used to
extract data from the EDR is commercially

available, Mercedes-Benz USA, LLC ("MBUSA")
expressly disclaims any and all liability arising
from the extraction of this information by
unauthorized Mercedes-Benz personnel.
MBUSA will not share EDR data with others
without the consent of the vehicle owners or,
if the vehicle is leased, without the consent of
the lessee. Exceptions to this representation
include responses to subpoenas by law
enforcement; by federal, state or local govern-

ment; 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 February 2013, 13 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
R
child restraint system
R
child seat securing systems
The components of the restraint system work
in conjunction with each other. They can only
deploy their protective function if, at all times,
all vehicle occupants:
R
have fastened their seat belts correctly
(Y page 42)
R
have the seat and head restraint adjusted
properly (Y page 92)
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 92).
You also have to make sure that an air bag can
inflate properly if deployed (Y page 44).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupants in the event of an accident. For
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

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
WARNING
G
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.

belts“ (Y page 41) and "Air bags"
(Y page 44). There you can also find information on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occupants
in the event of an accident or the vehicle rolling over. This reduces the risk of vehicle occupants coming into contact with parts of the
vehicle interior or being ejected from the vehicle. Furthermore, the seat belt helps to keep
the vehicle occupant in the best position in
relation to the air bag.
The seat belt system comprises:
R
Seat belts
R
Emergency Tensioning Devices for the front
seat belts and the outer seat belts in the
rear
R
Seat belt force limiters for the front seat
belts and the outer seat belts in the rear
If the seat belt is pulled out of the belt outlet
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be
extracted any further.
The Emergency Tensioning Device tightens the
seat belt in an accident, pulling the belt close
against the body. However it does not pull the
vehicle occupant back in the direction of the
backrest.
The Emergency Tensioning Device does not
correct an incorrect seat position or the routing of an incorrectly fastened seat belt.
When triggered, a seat belt force limiter helps
to reduce the force exerted by the seat belt on
the vehicle occupant.
The seat belt force limiters for the front seats
are synchronized with the front air bags, which
absorb part of the deceleration force. This can
reduce the force exerted on the vehicle 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.
WARNING
G
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 42)
R
have the seat and head restraint adjusted
properly (Y page 92)
WARNING
G
The seat belt does not offer the intended
level of protection if you have not moved the
backrest to an almost vertical position.
When braking or in the event of an accident,
you could slide underneath the seat belt and
sustain abdomen or neck injuries, for example. This poses an increased risk of injury or
even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest is in an almost vertical position and that
Z

the shoulder section of your seat belt is
routed across the center of your shoulder.
WARNING
G
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
Safety
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.
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 53) 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 47)
WARNING
G
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 dam-
aged 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.
Sports seat or AMG Performance seat: this
seat is designed for the standard three-point
seat belt. If you install another multi-point seat
belt, e.g. sport or racing seat belts, the
restraint system cannot provide the best level
of protection.
WARNING
G
If you feed seat belts through the opening in
the seat backrest, the seat backrest may be
damaged or may even break in the event of
an accident. This poses an increased risk of
injury or even fatal injury.
Only use the standard three-point seat belt.
Never modify the seat belt system.
Proper use of the seat belts
Observe the safety notes on the seat belt
(Y page 41).
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
Page 45
Only then can the forces which occur be distributed 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. Where possible,
adjust the seat belt to the appropriate
height.
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
"Loading guidelines" for securing objects, luggage or loads (Y page 250).
Fastening and adjusting the seat belts
Observe the safety notes on the seat belt
(Y page 41) and the notes on correct use of
seat belts (Y page 42).

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.
Safety
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 front 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
door is opened again, the 7 seat belt warning lamp goes out.
If the driver's seat belt is not fastened after
the engine is started, an additional warning
tone will sound. The warning tone switches off
after six seconds or once the driver's seat belt
is fastened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and frontpassenger 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 51).
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
WARNING
G
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
R
have fastened their seat belts correctly,
including pregnant women
R
are sitting correctly and maintain the
greatest possible distance to the air bags
R
follow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occupants.
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
Page 47
Occupant safety
45
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
Child restraint systems should be installed
on the rear seats.
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 40).
R
Always observe the instructions and safety
notes on the "Occupant Classification System (OCS)" (Y page 47) and on "Children
in the vehicle" (Y page 53) 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.
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, side
windows, rear side trim or side walls
R
no heavy, sharp-edged or fragile objects are
in the pockets of your clothing. Store such
objects in a suitable place
WARNING
G
If you modify the 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.
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 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 front-
!
passenger 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 front seats.
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the frontpassenger front air bag (Y page 40).
The front-passenger front air bag will only
deploy if:
R
the system, based on the OCS weight sensor readings, detects that the front-

Knee bags
Safety
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.
The driver's and front-passenger knee bags
offer additional thigh, knee and lower leg protection for the occupants in the front seats.
Side impact air bags
WARNING
G
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.
Front side impact air bags : and rear 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. It also offers
additional pelvis protection for occupants in
the front seats. 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.
Page 49
Occupant safety

Window curtain air bags
Window curtain air bags : are integrated into
the side of the roof frame and deployed in the
area from the A-pillar to the C-pillar.
When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protect the chest or
arms.
If the restraint system control unit detects a
side impact, the window curtain air 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 window curtain air bag may be
deployed in other accident situations
(Y page 51).
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 window curtain air bag
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 it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the correct positioning of
the child restraint system. Never place objects
under or behind the child restraint system, e.g.
a cushion. The entire base of the child
restraint system must always rest on the seat
cushion of the front-passenger seat. The backrest of the forward-facing child restraint system must lie as flat as possible against the
backrest of the front-passenger seat.
The child restraint system must not touch the
roof or be subjected to a load by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation and operating instructions.

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 213). When the frontpassenger seat is occupied, always pay attention to the PASSENGER AIR BAG OFF indicator
lamp. Be aware of the status of the frontpassenger front air bag both before and during
the journey.
WARNING
G
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag
is disabled. It will not be deployed in the
event of an accident and cannot perform its
intended protective function. A person in the
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.
WARNING
G
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).

WARNING
G
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat
too close to the dashboard, in the event of
an accident, the child could:
R
come into contact with the vehicle's interior if the PASSENGER AIR BAG OFF indicator lamp is lit, for example
R
be struck by the air bag if the
PASSENGER AIR BAG 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 belt sash guide to the shoulder
belt guide on the child restraint system. The
shoulder belt strap must be routed forwards
and downwards from the vehicle belt sash
guide. If necessary, adjust the vehicle belt
sash guide and the front-passenger seat
accordingly. Always observe the child
restraint system manufacturer's installation
instructions.
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
child restraint system and the child's stat-
ure. It is recommended that you install the
child restraint system on a suitable rear
seat.
R
The front-passenger seat is occupied by a
person of smaller stature (e.g. a teenager or
small adult), 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. Alternatively, a
person of smaller stature can sit on a rear
seat.
-
If the PASSENGER AIR BAG OFF indicator
lamp is lit, a person of smaller stature
should not use the front-passenger seat.
R
The front-passenger seat is occupied by an
adult or a person of 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 53).
When the Occupant Classification System

Safety
passenger front air bag might be triggered
unintentionally or might not be triggered at
all in the event of an accident with high
deceleration. This poses an increased risk of
injury or even fatal injury.
In this case the front-passenger seat may
not be used. Do not install a child restraint
system on the front-passenger seat. Have
the Occupant Classification System (OCS)
checked and repaired immediately at a
qualified specialist workshop.
WARNING
G
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the self-test, the frontpassenger front air bag is deactivated. It will
not be deployed in the event of an accident.
In this case, the front-passenger front air
bag cannot perform its intended protective
function, e.g. when a person is seated in the
front-passenger seat.
That person could, 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
deactivated in accordance with the person in the front-passenger seat
R
the person is seated properly with a correctly fastened seatbelt
R
the front-passenger seat has been moved
as far back as possible
If the PASSENGER AIR BAG OFF indicator
lamp remains lit when it should not, the
front-passenger seat must not be used. Do
not install a child restraint system on the
front-passenger seat. Have the Occupant
Classification System (OCS) checked and
repaired immediately at a qualified specialist
workshop.
WARNING
G
Objects between the seat surface and the
child restraint system could affect OCS
operation. This could result in the frontpassenger air bag not functioning as intended during an accident. This poses an
increased risk of injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. The
entire base of the child restraint system
must always rest on the seat cushion of the
front-passenger seat. The backrest of the
forward-facing child restraint system must,
as far as possible, be resting on the backrest of the front-passenger seat. Always
comply with the child restraint system manufacturer's installation instructions.
After the self-test, the PASSENGER AIR BAG
OFF or the PASSENGER AIR BAG ON indicator
lamp displays the status of the frontpassenger front airbag (Y page 47). If the
front-passenger front airbag is enabled, the
PASSENGER AIR BAG ON indicator lamp lights
up for 60 seconds and then goes out.
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 airbag. The PASSENGER AIR
BAG OFF indicator lamp may be lit continuously or be off.

bags continue to perform their protective func-
Safety
tion for the vehicle occupants in the event of a
crash.
WARNING
G
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.
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.
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 40)
R
the seat belt buckle tongue has engaged in
the belt buckle of the respective front seat
The Emergency Tensioning Devices in the rear
passenger compartment are triggered independently of the lock status of the seat belts.
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
R
Window curtain air bag, if the system determines that deployment can offer additional
protection to that provided by the seat belt
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 40).
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.
Page 55
Children in the vehicle
53
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 bags on the side where the
impact takes place, independently of the
Emergency Tensioning Device and the use
of the seat belt on the driver's seat and
outer seats in the second row
The side impact air bag on the front
passenger side deploys under the following
conditions:
-
the OCS system detects that the front
passenger seat is occupied or
-
the seat belt buckle tongue is engaged in
the belt buckle of the front passenger
seat
R
Window curtain air bag on the side of
impact, independently of the use of the seat
belt and independently of whether the frontpassenger seat is occupied
R
Emergency Tensioning Devices, if the system determines that deployment can offer
additional protection in this situation
R
Window curtain air bags on the driver's and
front-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer additional protection to that provided by the
seat belt
Not all air bags are deployed in an acci-
i
dent. 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:
R
Head-on collision
R
Side impact
R
Rollover
Automatic measures after an accident
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
R
the hazard warning lamps are switched on
R
the emergency lighting is activated
R
the vehicle doors are unlocked
R
the front side windows are lowered
R
the engine is switched off and the fuel supply is cut off
R
vehicles with Mercedes me connect: automatic emergency call
Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children
secured in the front-passenger seat. For this
reason, Mercedes-Benz strongly advises that
you install a child restraint system on a rear
seat. Children are generally better protected
there.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling in the
vehicle:
R
always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropriate to the age, weight and size of the child.
R
be sure to observe the instructions and
safety notes in this section in addition to the
Safety

child restraint system manufacturer's installation instructions.
R
always observe the instructions and safety
notes on the "Occupant classification system (OCS)". (Y page 47)
WARNING
G
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:
R
release the parking brake.
Safety
R
shift the automatic transmission out of
the parking position P.
R
start the engine.
In addition, they may operate vehicle equipment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle.
Never leave children unsupervised in the
vehicle.
WARNING
G
If persons, particularly children are subjected to prolonged exposure to extreme heat
or cold, there is a risk of injury, possibly
even fatal. Never leave children unattended
in the vehicle.
WARNING
G
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Children may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight.
Protect it with a blanket, for example. If the
child restraint system has been exposed to
direct sunlight, let it cool down before securing the child in it. Never leave children unattended in the vehicle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting properly. Particular attention must be paid
to children.
Observe the safety notes on the seat belt
(Y page 41) and the notes on correct use of
seat belts (Y page 42).
A booster seat may be necessary to achieve
proper seat belt positioning for children over
40 lbs (18 kg) until they reach a height where
a three-point seat belt can be properly fastened without a booster seat.
Special seatbelt retractor
WARNING
G
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt
retractor is disabled and the inertia real
draws in a portion of the seat belt. The seat
belt cannot be immediately refastened.
There is an increased risk of injury, possibly
even fatal.
Stop the vehicle immediately, paying attention to road and traffic conditions. Reactivate the special seat belt retractor and
secure the child restraint system properly.
All seat belts in the vehicle, except the driver's
seat belt, are equipped with a special seat belt
retractor. When activated, the special seat belt
retractor ensures that the seat belt cannot
slacken once the child seat is secured.
Installing a child restraint system:

If you install a rearward-facing child restraint
system on the center rear seat, the rear seat
armrest must be folded back as far as it will
go.
You can obtain further information about the
correct child restraint system from any authorized Mercedes-Benz Center.
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.
You will find further information on stowing
objects, luggage or loads under "Loading
guidelines" (Y page 250).
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.
The securing systems of child restraint systems are:
R
the seat belt system
R
the LATCH-type (ISOFIX) securing rings
R
the Top Tether anchorages
If it is absolutely necessary to carry a child on
the front passenger seat, be sure to observe
the information on the "Occupant Classification System (OCS)" (Y page 47). There you will
also find information on disabling the front

All child restraint systems must meet the following standards:
R
U.S. Federal Motor Vehicle Safety Standards
213 and 225
R
Canadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system
corresponds to the standards can be found on
an instruction label on the child restraint system. This confirmation can also be found in
the installation instructions that are included

Safety
Observe the warning labels in the vehicle interior and on the child restraint system.
LATCH-type (ISOFIX) child seat
securing system
WARNING
G
For LATCH-type (ISOFIX) child restraint systems in which the child is secured using the
safety belt integrated in the child restraint
system, the maximum permissible weight of
the child and child restraint system together
is 73 lbs (33 kg).
If the child and the child restraint system
together weigh more than 73 lbs (33 kg), the
LATCH-type (ISOFIX) child restraint system
with integrated safety belt no longer offers
sufficient protection. The LATCH-type (ISOFIX) child seat securing system may be overloaded, and the child may not be restrained
in an accident, for example. This poses an
increased risk of injury or even fatal injury.
If the child and the child restraint system
together weigh more than 73 lbs (33 kg),
use only a LATCH-type (ISOFIX) child
restraint system in which the child is also
secured with the vehicle seat belt. Also
secure the child restraint system with the
Top Tether belt, if available.
Regularly check that the permissible gross
weight of the child together with the child
restraint system is still maintained.
Always comply with the manufacturer's installation and operating instructions for the child
restraint system used.
Before every trip, make sure that the LATCHtype (ISOFIX) child restraint system is engaged
correctly in both LATCH-type (ISOFIX) securing
rings
When installing the child restraint system,

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. Please pay special attention to
the notes on tires, recommended minimum
tire tread depths, etc. (Y page 305).
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
Observe the "Important safety notes" sec-
i
tion (Y page 60).
WARNING
G
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 233) and
display messages which may be shown in the
instrument cluster (Y page 204).
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.
Off-road ABS
An ABS system specifically suited to off-road
terrain is activated automatically once the offroad program is activated (Y page 170).
At speeds below 20 mph (30 km/h), the front
wheels lock cyclically during braking. The digging-in effect achieved in the process reduces
Page 63
Driving safety systems
61
the stopping distance on off-road terrain. This
limits steering capability.
BAS (Brake Assist System)
General information
BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
Observe the "Important safety notes" sec-
i
tion (Y page 60).
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.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
Active Brake Assist
General information
Observe the "Important safety notes" sec-
i
tion (Y page 60).
Active Brake Assist consists of a distance
warning function with an autonomous braking
function and a situation-dependent brake
boosting effect.
Active Brake Assist can help you to minimize
the risk of a collision with the vehicle traveling
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 vis-
ual collision warning or the warning tone,
autonomous braking can be initiated in critical
situations. If you apply the brake yourself in a
critical situation, Active Brake Assist supports
you with a situation-dependent brake boosting
effect.
Important safety notes
Detection of hazardous situations can be particularly 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 124).
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 no visible damage to the
front of the vehicle is apparent.
Activating/deactivating
Active Brake Assist is active after every ignition cycle.
You can activate or deactivate Active Brake
Assist (Y page 197) in the on-board computer. 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.
If you have activated DSR, Active Brake Assist
is deactivated. For further information on DSR,
see (Y page 169).

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.
Important safety notes
Observe the "Important safety notes" sec-
i
Safety
tion for driving safety systems (Y page 60).
WARNING
G
The distance warning function does not
react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
The distance warning function may not give
warnings in all critical situations. There is a
risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
Always adapt your speed to suit the prevailing road and traffic conditions.
WARNING
G
The distance warning function cannot
always clearly identify objects and complex
traffic situations.
In such cases, the distance warning function
may:
R
give an unnecessary warning
R
not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic
situation and do not rely solely on the distance warning function.
Function
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 the driver with the
autonomous braking function.
The autonomous braking function:
R
gives the driver more time to react to critical
driving situations
R
can help the driver to avoid an accident or
R
can reduce the effects of an accident
Vehicles without Active Distance Assist
DISTRONIC: 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
Vehicles with Active Distance Assist
DISTRONIC: the autonomous braking function
is available in the following speed ranges:
R
4 - 124 mph (7 - 200 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.

Situation-dependent braking assistance
General information
Observe the "Important safety notes" sec-
i
tion (Y page 60).
With the help of the radar sensor system,
Active Brake Assist can detect obstacles that
are in the path of your vehicle for an extended
period of time.
If Active Brake Assist detects a risk of collision
with the vehicle in front, it calculates the brake
pressure necessary to avoid a collision. If you
apply the brakes forcefully, situation-dependent braking assistance adapts to the situation
and automatically increases the brake pressure to a degree appropriate to the traffic situation.
Situation-dependent braking assistance provides braking assistance in hazardous situations at speeds above 4 mph (7 km/h). It uses
radar sensor technology to assess the traffic
situation.
Situation-dependent braking assistance is
capable of reacting to moving objects that
have already been detected as such at least
once over the period of observation, up to
vehicle speeds of around 155 mph
(250 km/h).
Situation-dependent braking assistance can
also detect stationary objects, up to vehicle
speeds of around 44 mph (70 km/h).
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
Situation-dependent braking assistance is then
deactivated.
Important safety notes
Observe the "Important safety notes" sec-
i
tion for driving safety systems (Y page 60).
WARNING
G
Active Brake Assist does not react:
R
to persons, bicycles, motorcycles or animals
R
to approaching vehicles
R
to cross traffic
R
on bends
As a result, Active Brake Assist cannot intervene in all critical situations. There is a risk
of an accident.
Always pay careful attention to the traffic
situation and be prepared to brake.
Always pay careful attention to the traffic
situation and be ready to brake. Terminate
the intervention in a non-critical driving situation.
Due to the nature of the system, complex but
non-critical driving conditions may also cause
Active Brake Assist to intervene.
Even if Active Brake Assist is not available due
to a malfunction in the radar sensor system,
the brake system is still available with full
brake boosting effect and BAS.
ESP®(Electronic Stability Program)
General notes
Observe the "Important safety notes" sec-
i
tion (Y page 60).
ESP®monitors driving stability and traction,
i.e. power transmission between the tires and

ETS/4ETS (Electronic Traction System)
Observe the "Important safety notes" sec-
i
tion (Y page 60).
ETS traction control is part of ESP®. On vehicles with 4MATIC, 4ETS is part of ESP®.
Safety
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®.
Off-road 4ETS (Electronic Traction System)
A 4ETS system specifically suited to off-road
terrain is activated automatically once the offroad program is activated (Y page 170).
