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.

transmission, brake and tire wearare affected
by these factors:
R
operating conditions of your vehicle
R
your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R
avoid short trips as these increase fuel
consumption.
R
always make sure that the tire pressures
are correct.
R
do not carry any unnecessary weight.
R
remove roof racks once you no longer need
them.
R
a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R
always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R
do not depress the accelerator pedal when
starting the engine.
R
do not warm up the engine when the vehicle
is stationary.
R
drive carefully and maintain a safe distance
from the vehicle in front.
R
avoid frequent, sudden acceleration and
braking.
R
change gear in good time and use each gear
only up to Ô of its maximum engine speed.
R
switch off the engine in stationary traffic.
R
keep an eye on the vehicle's fuel
consumption.
Environmental concerns and
recommendations
Wherever the operating instructions require
you to dispose of materials, first try to
regenerate or re-use them. Observe the
relevant environmental rules and regulations
when disposing of materials. In this way you
will help to protect the environment.

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 functionsare only available
with limitations,or not at all.This could affect,
for example, the power steering and thebrake
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
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other
networked components. In particular,
systems relevant to safety could also be
affected. As a result, these may no longer
function as intended and/or jeopardize the
operating safety of the vehicle. There is an
increased risk of an accident and injury.
Never tamper with the wiring as well as
electronic components or their software. You
should have all work to electrical and
electronic equipment carriedout at aqualified
specialist workshop.
!
There is a risk of damage to the vehicle if:
R
the vehiclebecomes stuck,e.g. on a high
curb or an unpaved road
R
you drive too fastover 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.
If the underbody paneling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody paneling. If
these materials come in contact with hot
parts of the exhaust system for an
extended period, they can catch fire.
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.

If SRS is malfunctioning, child restraint
systemcomponents 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

Occupant safety
Triggering of Emergency Tensioning
Devices and air bags
During the first stage of a collision, the air bag
control unit evaluates important physical
data relating to vehicle deceleration or
acceleration, such as:
R
duration
R
direction
R
magnitude
Based on the evaluation of this data, the air
bag control unit pre-emptively triggers the
Emergency Tensioning Device in the first
stage.
If there is an even higher rate of vehicle
deceleration or acceleration in a longitudinal
direction, the front air bagsare also deployed.
Your vehicle has adaptive, two-stage front air
bags. The air bag control unit evaluates
vehicle deceleration or acceleration in the
event of a collision. 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 reached within a few
milliseconds.
The Emergency Tensioning Device and air bag
triggering thresholds are variable and are
adapted to the detected rate of deceleration
or acceleration of the vehicle. This process is
pre-emptive in nature. The triggering process
must take place in good time at the start of
the collision.
The rate of vehicle deceleration or
acceleration and the direction of the force are
essentially determined by:
R
the distribution of forces during the
collision
R
the collision angle
R
the deformation characteristics of the
vehicle
R
the characteristics of the object with which
the vehicle has collided
Factors that 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 may be deformed significantly,
e.g. the hood or the fender, 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
Safety
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.
i
The front Emergency Tensioning Devices
can only be triggered if the seat belt
tongues on the front seats are correctly
engaged in the seat belt buckles.
i
Not all air bags are deployed in an
accident. The differentair bag systems
work independently of each other.
How the air bag system works is
determined by predicting the severity of
the accident, especially vehicle
deceleration or acceleration, and the type
of accident:
R
head-on collision
R
side impact
R
rollover
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

Improper repairwork 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.
Consult 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 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
Do not touch the air bag parts. Have the
deployed air bags replaced at a qualified
specialist workshop as soon as possible.
WARNING
G
Air bags are designed to reduce the potential
of injury and fatality in certain:
R
frontal impacts (driver's/front-passenger
air bags and knee bags)
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 temporarily comes out of
the air bags. This dust, however, is generally
neither harmful to your health, nor does it
indicate a fire in the vehicle. In order to
preventpotential breathing difficulties, you
may wish to get out of 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.

Important safety notes
WARNING
G
Using unsuitable seat covers could restrictor
even preventdeployment of the air bags
integrated into the seats. Consequently, the
air bags cannot protectvehicle 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
The air bag parts are hot after the airbag has
been deployed. There is a risk of injury.
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 seatbelt and makesure
that it is correctly positioned on your body.

As the airbag 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

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 holdthe 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.
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
affect your hearing. The powder that is
released generally does not constitute a
health hazard anddoes not indicatethat 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 bag installation locations are
identified by the AIR BAG symbol.
The air bags are deployedif the air bag control
unit detects the need for deployment.Only in
the event of such a situationwill the air bags
provide their supplemental protection.
If the driverand front passengerdo 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 extentpossible by a properly fastened
seat belt. Aproperly fastened seat beltis 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

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
depending on whether the seatbelt is being
used
R
independently of other air bags in the
vehicle
If the vehicle rolls over, the front air bags are
generally not deployed.
Your vehicle has adaptive, two-stage front air
bags. The air bag control unit evaluates
vehicle deceleration or acceleration in the
event of a collision. In the first deployment
stage, the front air bag is filled with part of the
total available propellant gas, thereby
reducing the risk of injury. If the air bag
control unit recognizes within a few
milliseconds that the vehicle is being braked
or accelerated faster than originally
predicted, the front air bag is filled with the
maximum amountof propellant gas available.
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 45).
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

to the function of the sensors being impaired.
The air bags might therefore not function
properly any more. Consequently, theair bags
cannot protectvehicle 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.
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 impactair bags. Otherwise,
the side impact air bags cannot deploy
correctly and therefore cannot provide the
intended protection in the event of an
accident.
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 of the thorax for
occupants on the front seats as well as also
of the pelvis for the vehicle occupants on the
side of the vehicle on which the impact
occurs. However, they do not protect the:

WARNING
G
According to accident statistics, children are
saferwhen 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 inyour 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
Achild 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 yourvehicle. 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

Proper 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 frontair bag, driver's side knee
bag, front-passengerfront air bag, side
impact air bags, windowcurtain airbags 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,
driver's side knee bag and ETDs) and side
(side impact air bags, windowcurtain air
bags, and ETDs) impacts which exceed
preset deploymentthresholds 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.

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.
Position the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your
abdomen, it could cause serious injuries in
a crash.
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.
Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
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.
Seat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distributeimpact forces.
The twisted seat belt against yourbody
could cause injuries.
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.
Place the seat backrest in a position that is
as upright as possible.
Check your seat belt during travel to make
sure it is properly positioned.
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.
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.
Achild'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 securedin the child
restraint.

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, the Emergency
Tensioning Device could be triggered in the
event of an accident.
The front seat belts and the outer seat belts
in the rear are equipped with Emergency
Tensioning Devices and seat belt force
limiter.
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.
The ETDs can only be activated when:
R
the ignition is switched on.
R
the restraint systems are operational; see
"6 SRS warning lamp" (Y page 39).
R
the belt tongue is engaged in the buckle on
each of the front seat belts.
The ETDs on the outside seats in the rear

Safety
can provide additional protection.
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 anddoes not indicatethat 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.
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.
The seat belt force limiter for the front seats
are synchronized with the front air bags,
which take on a partof the deceleration force.
This results in the force exerted on the
occupant being distributed over a greater
area.

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 properlysecured in anappropriate
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 toptether strap, orlower 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
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
Achild 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
completely eliminate this risk is to never
place a child in a rear-facing child restraint
in the front seat. We therefore strongly
Page 57
Children in the vehicle
Information Provided by:
55
recommend that you always place a child
in a rear-facing child restraintin 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 checkinstallation.
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.
Achild 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 restrainton the frontpassenger
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

Important safety notes
If you fail to adapt yourdriving 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 yourdriving style to
suitthe prevailing road, weather and traffic
conditions and maintain asafe 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. Pay particular attention
to the informationregarding tires,
recommended minimum tire tread depths
etc.inthe "Wheels and tires" section
(Y page 312).
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

become inoperative. Observe the information
on the ABS warning lamp (Y page 242) and
display messages which may be showninthe
instrument cluster (Y page 213).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface
conditions. ABS works on slippery roads,
even if you only brake gently.
Braking

If ABS intervenes: continue todepress 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

Observe the "Important safety notes"
section for driving safety systems
(Y page 61).
WARNING
G
The distance warning function does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.

Always pay careful attention to the traffic
situationand be ready to brake.
The distance warning functioncannot always
clearly identify objects and complextraffic
situations.
In such cases, the distance warning function
may:
R
give an unnecessary warning
R
not give a warning
Always pay careful attention to the traffic
situation and do not rely solely on the
distance warning function.
Function
X
To activate/deactivate: activate or
deactivate the distance warning function in
the on-board computer (Y page 204).
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.Without your intervention, the
distance warning function cannot prevent a
collision.
Starting at a speed of around 4 mph
(7 km/h) thedistancewarning function warns
you if you rapidly approach a vehicle in front.
An intermittentwarning 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 provideditis safe to do
so.
For the distance warning function to assist
you when driving, the function must be
activated in the on-board computer and be
operational (Y page 204).
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.
In particular, the detection of obstacles can
be impaired if:
R
dirt on the sensors or anything else
covering the sensors
R
snow or heavy rain
R
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 fronton a different line
relative to the center of your vehicle
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
Adaptive Brake Assist

WARNING
G
Adaptive Brake Assist does not react:
Safety
R
to people or animals
R
to oncoming vehicles

R
to stationary obstacles
R
when cornering
As a result, Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic
situationand be ready to brake.
Due to the nature of the system, particularly
complicated but non-critical driving
conditions may also cause Brake Assist to
intervene.
Adaptive Brake Assist aids you in braking
during hazardous situations at speeds above
4mph (7 km/h) and uses the radar sensor
system to evaluate the traffic situation.
With the help of a sensorsystem, adaptive
Brake Assistcan 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 riskof
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 againif:
R
you release the brake pedal
R
there is no longerany dangerofarear-end
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
of reacting to moving objects that have
already been recognized as suchat least once
over the period of observation. Adaptive
Brake Assist does not react to stationary
obstacles.
If Adaptive Brake Assist is not available due
to a malfunction in the radar sensor system,
the brake system remains available with full
brake boosting effect and BAS.
In particular, the detection of obstacles can
be impaired if there is:
R
dirt on the sensors or anything else
covering the sensors
R
snow or heavy rain
R

ESP®(Electronic Stability Program)
General notes
i
Observe the "Important safety notes"
section (Y page 61).
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 61).
ETS/4ETS traction control is part of ESP®.
ETS brakes the drive wheels individually if
they spin. This enables you to pull away and
accelerate on slippery surfaces, for example
if the road surface is slippery on one side. In
addition, more drive torque is transferred to
the wheel or wheels with traction.
ETS remains active when you deactivate
ESP®.
Important safety notes
WARNING
G
If ESP®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
