Important safety notes
G
WARNING
If service workis not carried out correctly, the
operating safety of your vehicle may be affec-
ted. This could cause you to lose control of
your vehicle and cause an accident. More-
over, the safety systems may no longer be
able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop.
G
WARNING
Modifications to or work performed incor-
rectly on the following parts can result in the
restraint systems not functioning as intended:
R
the restraint system, consisting of seat
belts and their anchorage points, belt ten-
sioners, belt force limiters and airbags
R
the wiring
R
networked electronic systems
Airbags and belt tensioners could fail to
deploy or be triggered in an accident despite
the deceleration force being sufficient to trig-
ger the systems, or could be triggered unin-
tentionally. For this reason, never make any
modifications to the restraint systems.
Therefore, you must not tamper with elec-
tronic components or their software.
The seat belts, together with SRS (Supple-
mental Restraint System), are complemen-
tary, co-ordinated restraint systems
(Y page 39). They reduce the risk of injury
in specific, pre-defined types of accident sit-
uations and thereby increase occupant
safety. However, seat belts and airbags gen-
erally do not protect against objects pene-
trating the vehicle from the outside.
To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R
the seat and head restraint are adjusted
properly (Y page 86).
R
the seat belt has been fastened properly
(Y page 45).
R
the airbags can inflate unrestricted if
deployed (Y page 40).
R
the steering wheel is adjusted properly
(Y page 91).
R
the restraint systems have not been modi-
fied.
An airbag increases the protection of vehicle
occupants wearing a seat belt. However, air-
bags are only an additional restraint system
which complements, but does not replace,
the seat belt. All vehicle occupants must wear
their seat belt correctly at all times, even if
the vehicle is equipped with airbags. The air-
bags are not deployed in all types of acci-
dents. For example, if the protective capacity
of correctly fastened seat belts is not
increased by deploying the airbags, the air-
bags will not deploy.
Airbag deployment only provides increased
protection if the seat belt is worn correctly.
The seat belt helps, firstly, to keep the vehicle
occupant in the best position in relation to the
airbag. Secondly, in a head-on collision, for
example, the seat belt prevents the vehicle
occupant from being propelledtowards the
point of impact.

SRS (Supplemental Restraint System)
Introduction
SRS consists of:
R
the 6 SRS warning lamp
R
airbags
R
airbag control unit (with crash sensors)
R
belt tensioners 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
SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
forces to which occupants are subjected dur-
ing an accident.
SRS warning lamp
G
WARNING
If SRS is malfunctioning, individual systems
may be triggered unintentionally or might not
be triggered in the event of an accident with
a high rate of vehicle deceleration.
A malfunction has occurred 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
warning lamp lights up again.
In this case, have SRS checked 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.
Triggering of belt tensioners, belt force
limiters and airbags
During the first stage of a collision, the airbag
control unit evaluates important physical
data relating to vehicle deceleration or accel-
eration, such as:
R
duration
R
direction
R
magnitude
Based on the evaluation of this data, the air-
bag control unit pre-emptively triggers the
belt tensioners in the first stage.
i
The front belt tensioners can only be trig-
gered if the seat belt tongues on the front
seats are correctly engaged in the seat belt
buckles.
If there is an even higher rate of vehicle decel-
eration or acceleration in a longitudinal direc-
tion, the front airbags are also deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluates vehi-
cle deceleration or acceleration in the event
of a collision. In the first deployment stage,
the front airbag is filled with a portion of the
available propellant gas in order to reduce the
risk of injuries. If, within a few milliseconds,
the airbag control unit detects that the vehi-
cle is accelerating or decelerating at a greater
rate than originally anticipated, the front air-
bag is then filled with the maximum amount
of propellant gas.
The belt tensioner and airbag 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.
i
Not all airbags are deployed in an acci-
dent. The different airbag systems work
independently of each other.
Occupant safety
39
Safety
Z
How the airbag system works is deter-
mined by predicting the severity of the acci-
dent, especially vehicle deceleration or
acceleration, and the type of accident:
R
head-on collision
R
side impact
The rate of vehicle deceleration or accelera-
tion and the directionofthe force are essen-
tially determined by:
R
the distribution of forces during the colli-
sion
R
the collision angle
R
the deformation characteristics of the vehi-
cle
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 airbag,
nor do they provide an indication of airbag
deployment.
The vehicle may be deformed significantly,
e.g. the bonnet or the wing, without an airbag
being deployed. This is the case if only parts
which are relatively easily deformed are affec-
ted and the rate of deceleration is not high.
Conversely, airbags may be deployed even
though the vehicle suffers only minor defor-
mation. 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.
Airbags
Important safety notes
G
WARNING
Airbags provide additional protection; they
are not, however, a substitute for seat belts.
Observe the following notes to reduce the risk
of serious or even fatal injury caused by airbag
deployment:
R
all vehicle occupants –inparticular, preg-
nant women – must wear their seat belt
correctly at all times and lean back against
the backrest, which should be positioned
as close to the vertical as possible. The
head restraint must support the back of the
head at about eye level.
R
always secure childrenless than
1.50mtall or under12years of age in suit-
able child restraint systems.
R
all vehicle occupants must select a seat
position that is as far away from the airbag
as possible. The driver's seat position must
allow the vehicle to be driven safely. The
driver's chest should be as far away from
the centre of the driver's airbag cover as
possible.
R
move the front-passenger seat as far back
as possible. This is especially important if
you have secured a child in a child restraint
system on the front-passenger seat.
R
vehicle occupants –inparticular, children
–must notlean their heads into the area of
the window in which the sidebag/window-
bag is deployed.
R
rearward-facing child restraint systems
must not be fitted to the front-passenger
seat unless the front-passenger airbag has
been disabled. On the front-passenger
seat, the front-passenger airbag is disabled
if a child restraint system with a trans-
ponder for automatic child seat recognition
is fitted to the front-passenger seat in a
vehicle equipped with automatic child seat
recognition. The 4 PASSENGER AIRBAG
OFF indicator lamp must be continuously
lit.
If the front-passenger seat of your vehicle
does not have automatic child seat recog-
nition, or your rearward-facing child
restraint system does not have automatic
child seat recognition, children must be
secured in a child restraint system on a
40
Occupant safety
Safety
suitable seat in the rear. If you secure a
forward-facing child restraint system to the
front-passenger seat, you must move the
front-passenger seat as far back as possi-
ble.
R
make sure there are no heavy or sharp-
edged objects in the pockets of clothing.
R
do not lean forwards, e.g. over the cover of
the driver's/front-passenger front airbag,
particularly when the vehicle is in motion.
R
do not put your feet on the dashboard.
R
only hold the steering wheel on the outside.
This allows the airbag to be fully deployed.
You could be injured if the airbag is
deployed and you are holding the inside of
the steering wheel.
R
do not lean on the doors from inside the
vehicle.
R
make sure that there are no people, ani-
mals or objects between the vehicle occu-
pants and the area where the airbags are
deployed.
R
do not place any objects between the seat
backrest and the door.
R
do not hang any hard objects, for example,
coat hangers, on the grab handles or coat
hooks.
R
do not attach accessories, e.g. cup holders,
to the doors.
It is not possible to rule out a risk of injury
being caused by an airbag, due to the high
speed at which the airbag must be deployed.
G
WARNING
Airbag functionality can only be assured if the
following parts are not covered and no badges
or stickers are attached to them:
R
padded steering wheel boss
R
kneebag cover below the steering column
R
front-passenger airbag cover
R
outer side of front seat bolsters
R
side trim next to the rear seat backrest
R
roof frame cover between the front A-pillar
and the C-pillar in the rear compartment
G
WARNING
Asmall amount of powder is released when
an airbag is deployed. The powder could
cause short-term breathing difficulties in peo-
ple with asthma or other respiratory prob-
lems.
In order to prevent breathing difficulties, you
should leave the vehicle as soon as it is safe
to do so. You can also open the window to
allow fresh air to enter the interior. The pow-
der does not constitute ahealth hazard and
does not indicate that there is a fire in the
vehicle.
G
WARNING
The airbag parts are hot after the airbag has
been deployed. Do not touch them as you
could burn yourself.
Have the airbags replaced at a qualified spe-
cialist workshop. Otherwise, occupants are
not protected by the airbags in the event of
another accident.
Airbag deployment slows down and restricts
the movement of the vehicle occupant, com-
plementing the restraint of the seat belt.
If the airbags 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. The 6 SRS warning lamp
lights up.
The airbag installation locations are identified
by the AIRBAG symbol.
Front airbags
!
Do not place heavy objects on the front-
passenger seat. The system may then
detectthat the seat is occupied and if there
is an accident, the restraint systems on the
front-passenger side could be deployed.
Have restraint systems that have been trig-
gered replaced.

If the vehicle overturns, the front airbags are
generally not deployed unless the system
detects high vehicle deceleration in a longi-
tudinal direction.
Front-passenger airbag ; is only activated if
the system detects that the front-passenger
seat is occupied. The PASSENGER AIRBAG
OFF indicator lamp 4 on the centre con-
sole is not lit (Y page 49). This means that
a child restraint system without automatic
child seat recognition has been fitted to the
front-passenger seat, or a child restraint sys-
tem with automatic child seat recognition has
been fitted incorrectly.
Driver's kneebag
Driver's kneebag : is always deployed along
with the driver's airbag and inflates under-
neath the steering column.
Driver's kneebag : increases the driver's
protection against:
R

R
lower leg injuries
Rear sidebags
G
WARNING
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat covers that have been approved
for Mercedes-Benzvehicles.
The seat covers must have a special tear seam
for sidebags. Otherwise, the sidebags cannot
deploy correctly and would fail to provide the
intended protection in the event of an acci-
dent. Appropriate seat covers can be
obtained, for example, from a Mercedes-Benz
Service Centre.
When deployed, the sidebags offer additional
protection for the thorax of the vehicle occu-
pants on the side of the vehicle on which the
impact occurs.However, they do not protect
the:

Seat belts
Important safety notes
G
WARNING
A seat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot provide the intended
level of protection. Under certain circumstan-
ces, this could cause severe or even fatal inju-
ries in the event of an accident.
Therefore, make sure that all occupants —in
particular, pregnantwomen —wear their seat
belts correctly at all times.
R
The seat belt must fit snugly on your body
and must not be , avoid
wearing bulky clothing, e.g. a winter coat.
The shoulder section of the belt must be
routed across the centre of your shoulder
—onno account across your neck or under
your arm —and pulled tight against your
upperbody. The lap belt must always pass
across your lap as low down as possible, i.e.
over your hip joints —not across your abdo-
men. If necessary, push the seat belt
slightly downwards and adjust it by pulling
it in the direction the seat belt retracts.
R
Do not route the seat belt strap over sharp
or fragile objects. Please make sure that
such objects are not on or in your clothing,
e.g. spectacles, pens or keys etc. The seat
belt strap could become damaged and tear
during an accident and you or other vehicle
occupants could be injured.
R
Only one person should use each seat belt
at any one time. Children must never travel
sitting on the lap of another occupant. The
child will not be secured in the event of an
accident, heavy braking or sudden change
of direction.This may result in the child or
other occupants being seriously or fatally
injured.
R
Persons under 1.50 mtall cannot wear the
seat belts correctly. For this reason secure
persons less than 1.50 m tall in specially
designed, suitable restraint systems.
R
Children under1.50 mtall and younger
than twelve years of age cannotwear the
seat belts correctly. For this reason secure
them in special suitable child restraint sys-
tems installed on a suitable seat. Additional
information can be found in the Operating
Instructions in the chapter "Safety", "Chil-
dren in the Vehicle". Observe the installa-
tion instructions of the child restraint sys-
tem manufacturer.
R
Do not secure an object with a seat belt if
the seat belt is also being used by one of
the vehicle's occupants.
G
WARNING
The seat belt does not offer the intended level
of protection unless the backrest is almost
vertical. Under certain circumstances, this
could cause severe or even fatal injuries in the
event of an accident.
Before starting a journey, make sure that the
seat is properly adjusted and that the back-
rest is almost vertical.
G
WARNING
Adirty or damaged seat belt or one that has
been modified or subjected to a load in an
accident no longer offers the intended level of
protection. Under certain circumstances, this
could cause severe or even fatal injuries in the
event of an accident.
44
Occupant safety
Safety
For this reason, check regularly that the seat
belts are not damaged or dirty.
Always have damaged seatbelts or seat belts
that have been subjected to a load in an acci-
dent replaced at a qualified specialist work-
shop.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat belts which have
been approved by Mercedes-Benz for your
vehicle.
Seat belts are the most effective means of
restraining the movement of vehicle occu-
pants in the event of an accident. This
reduces the risk of vehicle occupants coming
into contact with parts of the vehicle interior.

The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the front passenger have fastened their seat
belt.
For certain countries only: regardless of
whether the driver and the front passenger
have fastened their seat belts, the 7 seat
belt warning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the front passenger have fas-
tened their seat belts.

Belt tensioners, belt force limiters
G
WARNING
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at a qualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners. Any Mercedes-Benz
Service Centre can provide details of these
regulations.
!
If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
The frontseat belts are equipped with belt
tensioners and belt force limiters. The outer
seat belts in the rear are equipped with seat
belt tensioners.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
When triggered, seat belt force limiters help
to reduce the peak forceexerted by the seat
belt on the vehicle occupant.
The front belt force limiters are synchronised
with the front airbags, which take on a part of
the decelerationforce. Thus, the force exer-
ted on the occupant is distributed over a
greater area.
The belt tensioners can only be activated
when:
R
the ignition is switched on.
R
the restraint systems are operational; see
"SRS warning lamp" (Y page 39).
R
the belt tongue is engaged in the buckle on
each of the three-point seat belts in the
front.
The belt tensioners on the outside seats in the
rear compartment are triggered independ-
ently of the lock status of the seat belts.
The belt tensioners are triggered depending
on the type and severity of an accident:
R
in the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R
in the event of a side impact if the vehicle
is subjected to high lateral acceleration/
deceleration
If the airbags 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. The 6 SRS warning lamp

G
WARNING
To reduce the risk of serious or even fatal
injury to the child in the event of a sudden
change in direction, braking or an accident:
R
children less than 1.50 m tall and under
twelve years of age must always be secured
in special child restraint systems on a suit-
able vehicle seat. This is necessary

Safety
Z
because the seat belts are not designed for
children.
R
do not secure children less than 1.50mtall
and under twelve years of age on the front-
passengerseat. Exception:ifthe vehicle is
equipped with automatic child seat recog-
nition on the front-passenger seat and the
child is secured in a child restraint system
with transponders for automatic child seat
recognition
R
if you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible.
R
children must never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of a sudden
change of direction, heavy braking or an
accident, it would not be possible to
restrain the child. The child could be thrown
against parts of the vehicle interior and be
seriously or even fatally injured.
G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to a suitable vehicle seat. The child cannot be
restrained in the event of an accident, heavy
braking or sudden changes of direction. The
child could be seriously or even fatally injured.
For this reason, when fitting a child restraint
system, observe the manufacturer's installa-
tion instructions and the correct use of the
child restraint system.
Child restraint systems should be fitted to the
rear seats. Children are generally better pro-
tected there.
The entire base of the child restraint system
must always rest on the seat cushion. There-
fore, never place objects, e.g. a cushion,
under the child restraint system.
Only use child restraint systems with the orig-
inal cover designed for them. Only replace
damaged covers with genuine Mercedes-Benz
covers.
We recommend the use of child restraint sys-
tems which have been approved for
Mercedes-Benzvehicles.
G
WARNING
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system. They could injure them-
selves on parts of the vehicle. They could also
be seriously or even fatally injured by pro-
longed exposure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. Parts of the child restraint sys-
tem could heat up and the child could burn
herself/himself on them.
If a child opens a door, the child or other per-
sons could be injured as a result. They could
get out and injure themselves or be injured by
a passing vehicle.
Also observe the notes on HOLD.Relevant
information can be found in the index.
G
WARNING
Unsecured or incorrectly positioned loads
increase the risk of injury for children and all
other occupants in the event of:
R
an accident
R
a braking manoeuvre
R
a sudden change of direction
Do not carry heavy or hard objects in the vehi-
cle interior unless they are secured. You will
find further information under "Loading guide-
lines" in the index.
If a child is travelling in your vehicle, secure
the child using a child restraint system which
is appropriate to the size, age and weight of
the child and recommended for Mercedes-
Benz vehicles. You should preferably fit the
restraint system to a suitable rear seat. You
can also secure the child in the integrated
child seat (Y page 53). Make sure that the
child is secured in a child restraint system
throughout the trip.

Child seat on the front-passenger seat
G
WARNING
If the front-passenger airbag is not disabled:
R
a child secured in a child restraint system
on the front-passenger seat could be seri-
ously and even fatally injured by the front-
passenger airbag deploying. This is espe-
cially a risk if the child is in the immediate
vicinity of the front-passenger airbag when
it deploys.
R
never secure a child on the front-passenger
seat in a rearward-facing child restraint sys-
tem. Only secure a rearward-facing child
restraint system on a suitable rear seat.
R
always move the front-passenger seat to
the rearmostposition if you secure a child
in a forward-facing child restraint system
on the front-passenger seat.
The front-passenger airbag is not disabled:
R
on vehicles without automatic child seat
recognition on the front-passenger seat
R
in vehicles with automatic child seat rec-
ognition in the front-passenger seat, if no
special child restraint system with trans-
ponders for automatic child seat recogni-
tion in the front-passenger seat has been
fitted
R
on vehicles with automatic child seat rec-
ognition on the front-passenger seat, if the
PASSENGER AIRBAG OFF indicator lamp
4 is not lit.
To make you aware of this danger, a corre-
sponding warning sticker has been affixed on
the dashboard and on both sides of the sun
visor on the front-passenger side.
Information about recommended child
restraint systems is available at any
Mercedes-Benz Service Centre.

G
WARNING
If the 4 PASSENGER AIRBAG OFF indica-
tor lamp does not light up when the child
restraint system is fitted, the front-passenger
airbag has not been disabled. If the front-
passenger airbag deploys, the child could be
seriously or even fatally injured.

Z
Proceed as follows:
R
do not use a rearward-facing child restraint
system on the front-passenger seat.
R
fit a rearward-facing child restraint system
on a suitable rear seat.
or
R
only use a forward-facing child restraint
system on the front-passenger seat and
move the front-passenger seat to the rear-
most position.
R
have the automatic child seat recognition
checked at a qualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. a cushion, under the child
restraint system. The entire base of the child
restraint system must always rest on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-
tive function in the event of an accident, and
could lead to injuries.
G
WARNING
Do not place electronic devices on the front-
passenger seat, e.g.:
R
laptops, when switched on
R
mobile phones
R
cards with transponders, e.g. ski passes or
access cards
Signals from electronic equipment can cause
interference in the automatic child seat rec-
ognition sensor system. This can lead to a
system malfunction. This may cause the
4 PASSENGER AIRBAG OFF indicator
lamp to light up without there being a child
seat with transponders for automatic child
seat recognition fitted. The front-passenger
airbag will not then deploy during an accident.
It is also possible that the 6 SRS warning
lamp lights up and/or the 4 PASSENGER
AIRBAG OFF indicator lamp does not light up
briefly when you turn the key in the ignition
lock to position 2.
If your vehicle does not have automatic child
seat recognition
1
on the front-passenger
seat, this is indicated by a special sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. The sticker is
visible when you open the front-passenger
door.
The front-passenger seat sensor system for
child restraint systems detects whether a
special Mercedes-Benz child seat with a
transponder for automatic child seat recog-
nition has been fitted. In this case, 4

ISOFIX childseat securing system for
the rear seats
G
WARNING
Achild restraint system secured by the ISOFIX
child seat securing system does not provide
sufficient protection for children weighing
more than 22 kg. For this reason, do not
secure children weighing more than 22 kg in
a child restraint system secured by the ISOFIX
child seat securing system. If the child weighs
more than 22 kg, secure the child restraint
system using a three-point seat belt.
G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to a suitable vehicle seat. The child cannot be
restrained in the event of an accident, heavy
braking or sudden changes of direction. The
child could be seriously or even fatally injured.
For this reason, when fitting a child restraint
system, observe the manufacturer's installa-
tion instructions and the correct use of the
child restraint system.
For reasons of safety, only use child restraint
systems with the ISOFIX child seat securing
system on the rear seats.
We recommend that you use the ISOFIX child
restraint systems that have been recommen-
ded for Mercedes-Benz.
An incorrectly fitted child restraint system
could come loose and seriously or even fatally
injure the child or other vehicle occupants.
When fitting the child restraint system, always
make sure that it is engaged correctly in the
securing rings on both sides.
G
WARNING
Please note that if child restraint systems, or
their retaining systems, are damaged or sub-
jected to a load in an accident, they may not
be able to provide their protective function.
This could result in serious or even fatal inju-
ries to the secured child in the event of an
accident, heavy braking or a sudden change
in direction.
For this reason, have child restraint systems
and their anchorages which have been dam-
aged or subjected to a load in an accident
checked immediately at a qualified specialist
workshop.
!
When fitting the child restraint system,
make sure that the seat belt for the centre
seat does not get trapped. Otherwise, the
seat belt could be damaged.
ISOFIX is a standardised securing system for
specially designed child restraint systems on
the rear seats. The ISOFIX securing rings for
two ISOFIX child restraint systems are fitted
on the left and right of the rear seats.

WARNING
The risk of an accident is significantly
increased by driving too fast. This is particu-
larly the case when cornering as well as on
wet or slippery roads or when driving too close
to the vehicle in front.
The driving safety systems described in this
section can neither reduce this risk nor over-
ride the laws of physics.
For this reason, always adapt your driving
style to the prevailing road and weather con-
ditions. Maintain sufficient distance from
other road users and objects on the road.
If you fail to adapt your driving style, the driv-
ing 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 responsi-
ble for the distance to the vehicle in front, for
vehicle speed and for braking in good time.
Always adapt your driving style to suit the
prevailing road and weather conditions as
well as the traffic conditions, and maintain a
safe distance from the vehicle in front. Drive
carefully.
i
Please note that the driving safety sys-
tems described only work as effectively as
possible when there is adequate contact
between the tyres and the road surface.
Pay particular attention to the information
regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and
tyres" section (Y page 292).
In wintry driving conditions, always use
winter tyres (M+S tyres) and if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible.

Safety
ABS (Anti-lock Braking System)
Important safety notes
G
WARNING
If ABSis faulty, the wheels could lock when
braking. This limits the steerability of the vehi-
cle when braking and the braking distance
may increase.
If ABS is deactivated due to a malfunction,
then BAS and ESP are also deactivated. There
is an increased risk of your vehicle skidding in
certain situations.
You should always adaptyour driving style to
suit the prevailing road and weather condi-
tions.
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
ABS works from a speed of about 8 km/h
upwards, regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently.
The yellow ! ABS warning lamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is
running.
i
Observe the "Important safety notes" sec-
tion (Y page 62).
Brakes
G
WARNING
Do not depress the brake pedal several times
in quick succession (pumping). Pumping the
brake pedal reduces the braking effect.You
might otherwise not be able to stop the vehi-
cle in time and could cause an accident.
Depress the brake pedal firmly and smoothly.
X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation 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 indica-
tion of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.
BAS (Brake Assist)
G
WARNING
If BAS has malfunctioned, the braking system
remains available with full brake boosting
effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and the stopping distance may
increase.
X
Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
i
Observe the "Important safety notes" sec-
tion (Y page 62).
COLLISION PREVENTION ASSIST
General notes
COLLISION PREVENTION ASSIST consists of
the BAS PLUS system and the distance warn-
ing signal, which are described in the follow-
ing.
Distance warning
G
WARNING
The distance warning signal cannot always
clearly identify objects and complex traffic
situations.
Driving safety systems
63
Safety
Z
In such cases, the distance warning signal
may:
R
give an unnecessary warning
R
not give a warning
There is a risk of an accident. Always pay par-
ticularattention to the trafficsituation and be
ready to brake, especially if the distance
warning signal alerts you.
G
WARNING
The distance warning signal does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
Thus, the distance warning signal cannot pro-
vide a warning in all critical situations.There
is a risk of an accident. Always pay careful
attention to the traffic situation and be ready
to brake.
X
To activate/deactivate: activate or deac-
tivate the distance warning signal in the on-
board computer (Y page 199).
When the distance warning signal is activa-
ted, the multifunction display shows the
Ä symbol as long as the HOLD function is
not activated (Y page 162). On vehicles with
Active Parking Assist, the Ä symbol is dis-
played when position P is engaged or you are
driving faster than 35 km/h.
The distance warning signal can help you to
minimise the risk of a front-end collision with
a vehicle ahead or reduce the effects of such
a collision. If the distance warning signal
detects that there is a risk of a collision, you
will be warned visually and acoustically.The
distance warning signal cannot prevent a col-
lision without your intervention.
The distance warning signal will issue a warn-
ing at speeds of around 30 km/h or more if:
R
the distance to the vehicle in front is too
short for the speed you are driving at for
several seconds. The · distance warn-
ing lamp then lights up in the instrument
cluster.
R
you are rapidly approaching the vehicle in
front. An intermittent warning tone will
then sound and the · distance warning
lamp will light up in the instrumentcluster.
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.
For the distance warningsignal to assist you
when driving, the function must be activated
in the on-board computer (Y page 199) and
be operational.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning.
With the help of the radar sensor system, the
distance warning signal can detect obstacles
that are in the path of your vehicle for an
extended period of time.
At speeds up to approximately 70 km/h, the
distance warning signal may also detect sta-
tionary obstacles, for example, stopped or
parked vehicles.
If you approach an obstacle and the distance
warning signal 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 there is:
R
dirt on the sensors or anything else cover-
ing the sensors
R
snow or heavy rain
R
interference by other radar sources
R
the possibility of strong radar reflections,
for example, in multi-storey car parks
R
a narrow vehicle travelling in front, e.g. a
motorbike
R
a vehicle travelling in front on a different
line
Following damage to the front end of the vehi-
cle, have the configuration and operation of
64
Driving safety systems
Safety
the radarsensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the frontofthe vehicle.
i
Observe the "Important safety notes" sec-
tion (Y page 62).
BAS PLUS (Brake Assist System Plus)
G
WARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations. BAS
PLUS cannot intervene in these cases.
There is a risk of an accident. Always pay
careful attention to the traffic situation and be
ready to brake.
G
WARNING
BAS PLUS does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
to stationary obstacles
R
when cornering
As a result, BAS PLUS may not intervene in
critical situations. There is a risk of an acci-
dent. Always pay careful attention to the traf-
fic situation and be ready to brake.
BAS PLUS assists you in braking during haz-
ardous situations at speeds above 30 km/h
and uses the radar sensor system to evaluate
the traffic situation.
With the help of the radar sensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
Should you approach an obstacle and BAS
PLUS has detected a risk of collision, BAS
PLUS calculates the braking force necessary
to avoid a rear-end collision. Should you apply
the brakes forcefully, BAS PLUS will automat-
ically increase the braking force to a level
suitable for the traffic conditions.
X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if:
R
you release the brake pedal.
R
there is no longer any danger of a rear-end
collision.
R
no obstacle is detected in front of your
vehicle.
BAS PLUS is then deactivated.
Vehicles with PRE-SAFE
®
: if BAS PLUS
requires particularly high brake pressure, pre-
ventative passenger protection measures
(PRE-SAFE
®
) are deployed simultaneously.
Up to vehicle speeds of around 250 km/h,
BAS PLUS is capable of reacting to moving
objects that have already been recognised as
such at least once over the period of obser-
vation. BAS PLUS does not react to stationary
obstacles.
If BAS PLUS is not available due to a malfunc-
tion 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 cover-
ing the sensors
R
snow or heavy rain
R
interference by other radar sources
R
the possibility of strong radar reflections,
for example, in multi-storey car parks
R
a narrow vehicle travelling in front, e.g. a
motorbike
R
a vehicle travelling in front on a different
line
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle.

Adaptive brake lamps
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS
or BASPLUS, the brake lamps flash rapidly.
In this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
lightup continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h. You can also switch off
the hazard warning lamps using the hazard
warning switch button (Y page 99).
i
Adaptive brake lamps are only available in
certain countries.
ESP
®
(Electronic Stability Program)
Important safety notes
G
WARNING
If the ÷ warning lamp in the instrument
cluster flashes, proceed as follows:
R
do not deactivate ESP
®
under any circum-
stances.
R
only depress the accelerator pedal as far as
necessary when pulling away.
R
adapt your driving style to suit the prevail-
ing road and weatherconditions.
Otherwise, the vehicle could go into a skid.
ESP
®
cannot reduce the risk of an accident if
you drive too fast. ESP
®
cannot override the
laws of physics.
!
Switch the ignition off when:
R
the electric parking brake is being tested
using a brake dynamometer.
R
the vehicle is being towed with the front/
rear axle raised.
Application of the brakes by ESP
®
may oth-
erwise destroy the brake system.
If ESP
®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary, 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 slip-
pery roads. ESP
®
can also stabilise the vehi-
cle during braking.
If ESP
®
intervenes, the ÷ ESP
®
warning
lamp flashes in the instrument cluster.
i
Observe the "Important safety notes" sec-
tion (Y page 62).
i
Only use wheels with the recommended
tyre sizes. Only then will ESP
®
function
properly.
Traction control
Traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually 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.
Traction control remains active if you deacti-
vate ESP
®
.

trailer stabilisation
G
WARNING
If road and weather conditions are poor,
trailerstabilisation will not be able to prevent
the trailer fromswerving and will thus be
unable to reduce the risk of an accident. Trail-
ers with a high centre of gravity can tip over
before ESP
®
can detect this.
If your vehicle/trailer combination begins to
lurch, you can only stabilise the vehicle/
trailer combination by depressing the brake
firmly.
In this situation, ESP
®
assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP
®
slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has stabi-
lised.
Trailer stabilisation is active above speeds of
about 65 km/h.
Trailer stabilisation does not work if ESP
®
is
deactivated or disabled because of a mal-
function.
EBD (electronic brake force distribu-
tion)
G
WARNING
If EBDhas malfunctioned, the braking system
remains available with full brake boosting
effect.However, the rear wheels can still lock,
e.g. under full braking. This could cause you
to lose control of your vehicle and cause an
accident.You should therefore adapt your
driving style to the different handling charac-
teristics.
