Introduction to the restraint system
The restraint system reduces the risk of vehi- cle 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:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing system
The components of the restraint system work
in conjunction with each other. They can only
offer protection if all vehicle occupants
always:
R have the seat belt correctly fastened
(Y page 43)
R have the seat and head restraint adjusted
properly (Y page 109)
As the driver, you must also make sure that
the steering wheel is also adjusted properly.
Observe the information on the correct driv-
er's seat position (Y page 108).
In addition, you must make sure that the air-
bags can inflate properly if they are deployed (Y page 46).
An airbag supplements a correctly worn seat belt. As an additional safety device, the airbag
increases the level of protection for vehicle
occupants in the event of an accident. The
airbags are not deployed, for example, in the event of an accident in which sufficient pro-
tection is offered by the seat belt. In addition,
only those airbags, which in the applicable
accident situations offer additional protec-
tion, are deployed in the event of an accident.
However, the seat belt and airbag generally
do not protect against objects penetrating
the vehicle from the outside.
Information on how the restraint system
operates can be found under "Deployment of
belt tensioners and airbags" (Y page 54).40
Occupant safetySafety

light up continuously or flash. A warning tone
may also sound.
The 7 seat belt warning lamp goes out and
the warning tone stops as soon as the driver's
and the co-driver's seat belts have been fas-
tened.
i For more information on the
7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belt" (Y page 285).
Rear seat belt status indicator The seat belts on the left and centre rear
seats, when viewed in the direction of travel,
are not fastened. (Example)
The rear seat belt status indicator is only
available for certain countries.
For approximately 30 seconds, the rear seat
belt status indicator informs you which rear
seat belt is not fastened.
The rear seat belt status indicator appears if:
R you drive off and reach a speed of approx-
imately 10 km/h.
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion.
R someone gets in or out of the vehicle and
you pull away again.
You can also cancel the rear seat belt status
indicator immediately (Y page 251).Airbags
Introduction The installation location of an airbag is iden-
tified by the AIRBAG symbol. An airbag supplements a correctly worn seat
belt. It is not a replacement for the seat belt.
The airbag offers additional protection in
applicable accident situations.
Not all airbags are deployed in an accident.
The different airbag systems work independ-
ently of each other (Y page 54).
However, no system available today can com- pletely eliminate injuries and fatalities.
It is also not possible to completely rule out a
risk of injury caused by an airbag due to the
speed at which the airbag must be deployed.
Important safety notes G
WARNING
If you deviate from the correct seat position,
the airbag cannot perform its intended pro-
tective function and can even cause addi-
tional injuries when deployed. There is an
increased risk of serious or even fatal injuries.
In order to avoid such risks, always ensure
that all vehicle occupants:
R fasten their seatbelts correctly, including
pregnant women
R are seated correctly and maintain the fur-
thest possible distance from the airbags
R observe the following notes
Always ensure that there are no objects loca-
ted between the airbag and the vehicle occu-
pant.
R Adjust the seats properly before beginning
your journey. Always make sure that the
seat is in an almost upright position. The
centre 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 out-
side. This allows the airbag to be fully
deployed.
R Always lean against the backrest while driv-
ing. Do not lean forwards or lean against 46
Occupant safetySafety

Driver's airbag
:deploys in front of the
steering wheel. Front-passenger front air-
bag ;deploys in front of and above the glove
compartment.
When deployed, the front airbags offer addi-
tional head and thorax protection for the
occupants in the front seats.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps
inform you about the status of the front-
passenger front airbag (Y page 41).
The front-passenger front airbag will only
deploy if:
R the automatic front-passenger front airbag
deactivation system has detected that the
front-passenger seat is occupied
(Y page 49). The PASSENGER AIR BAG
ON indicator lamp is lit (Y page 50)
R the restraint system control unit predicts a
high accident severity
Driver's kneebag Driver's kneebag
:deploys under the steer-
ing column. The driver's kneebag is triggered
together with the front airbag.
The driver's kneebag offers additional thigh,
knee and lower leg protection for the occu-
pant in the driver's seat.
i The driver's kneebag is only available in
certain countries.
Sidebags G
WARNING
Unsuitable seat covers can obstruct or pre-
vent the deployment of the airbags integrated into the seats. Consequently, the airbags can-
not protect vehicle occupants as they are
designed to do. In addition, the function of the automatic front-passenger front airbag deac-
tivation 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 corresponding seats by Mercedes-Benz. Front sidebags
:and rear sidebags ;
deploy next to the outer bolster of the seat
backrest.
When deployed, the sidebag offers additional thorax protection. It also offers additional pel-
vis protection for occupants in the front
seats. However, it does not protect the:
R head
R neck
R arms 48

Pets in the vehicle
G
WARNING
If you leave animals unsupervised or unse-
cured in the vehicle, they may push a button
or a switch, for example.
They could:
R activate vehicle equipment and become
trapped, for example
R switch vehicle systems on or off, thus
endangering other road users
In the event of an accident, sudden braking or
abrupt changes of direction, unsecured ani-
mals could be flung around the vehicle, injur-
ing the vehicle occupants. There is a risk of an accident and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals correctly during a
journey, e.g. in an animal transport box. Driving safety systems
Driving safety systems overview
In this section, you will find information about the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
(Y page 73)
R BAS ( Brake Assist System) (Y page 74)
R COLLISION PREVENTION ASSIST PLUS
(Y page 74)
R Adaptive brake lamps (Y page 77)
R ESP ®
(Electronic StabilityProgram)
(Y page 77)
R EBD ( electronic brake force distribution)
(Y page 79)
R ADAPTIVE BRAKE (Y page 79)
R STEER CONTROL (Y page 79) Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can neither reduce the risk of an accident nor
override the laws of physics. Driving safety
systems are merely aids designed to assist
driving. You are responsible for maintaining
the distance to the vehicle in front, for vehicle
speed, for braking in good time, and for stay- ing in lane. Always adapt your driving style to
suit the prevailing road and weather condi-
tions 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 tyres and the
road surface. Please pay special attention to
the notes on tyres, recommended minimum
tyre tread depths etc. (Y page 352).
In wintry driving conditions, always use winter
tyres (M+S tyres) 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 notes 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.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched on. It goes out when the engine is running.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 73). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents. Driving safety systems
73Safety
Z

Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information on the ABS warning lamp (Y page 287) and
display messages which may be shown in the
instrument cluster (Y page 252).
ABS works from a speed of about 8 km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you
only brake gently.
Braking X
If ABS intervenes: continue to depress the
brake pedal 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; this serves as a reminder to take extra care while driving. BAS (Brake Assist)
General notes 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.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 73). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of 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 depressed firmly 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. COLLISION PREVENTION ASSIST
PLUS
General notes COLLISION PREVENTION ASSIST PLUS con-
sists of a distance warning function with an
autonomous emergency braking function and
adaptive Brake Assist.
COLLISION PREVENTION ASSIST PLUS can
help you to minimise the risk of a collision
with the vehicle in front or reduce the effects of such a collision.
If COLLISION PREVENTION ASSIST PLUS
detects that there is a risk of a collision, you
will be warned visually and acoustically. If you
do not react to the visual and audible collision warning, autonomous braking can be initiated
in critical situations. If you apply the brake
yourself in a critical situation, the COLLISION PREVENTION ASSIST PLUS adaptive Brake
Assist assists you.
Important safety notes In particular, the detection of obstacles can
be impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example, in
multi-storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle 74
Driving safety systemsSafety

X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if: R you release the brake pedal
R there is no longer any danger of a collision
R no obstacle is detected in front of your
vehicle
Adaptive Brake Assist is then deactivated.
If Adaptive Brake Assist demands particularly
high braking force, preventative passenger
protection measures (PRE-SAFE ®
) are activa-
ted simultaneously.
Up to a speed of approximately 250 km/h,
Adaptive Brake Assist is capable of reacting
to moving objects that have already been
detected as such at least once over the period of observation.
Up to a speed of approximately 70 km/h,
Adaptive Brake Assist reacts to stationary
obstacles. Adaptive brake lamps
The adaptive brake lights warn following traf- fic in an emergency braking situation:
R by flashing brake lamps
R the hazard warning lamps are activated
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS
or BAS PLUS, 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
light up 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 button (Y page 125). ESP
®
(Electronic Stability Program)
General notes i
Observe the "Important safety notes" sec-
tion (Y page 73).
ESP ®
monitors driving stability and traction,
i.e. power transmission between the tyres
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 stabilise 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 stabilise the vehicle during braking.
ETS/4ETS (Electronic Traction System) i
Observe the "Important safety notes" sec-
tion (Y page 73).
ETS traction control is part of ESP ®
. On vehi-
cles with 4MATIC, 4ETS is a component 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. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active if you deacti-
vate ESP ®
.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 73). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop. Driving safety systems
