Introduction to the restraint system
The restraint system can reduce the risk of vehi-
cle occupants coming into contact with parts of
the vehicle's interior in the event of an accident. Furthermore, the restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system includes:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing system The various components of the restraint system
work complementary to one another. They can
only perform their intended protective function
if all vehicle occupants:
R have correctly fastened their seat belt
(Y page 42)
R have correctly adjusted their seat and head
restraint (Y page 102).
As the driver, you must also ensure that the
steering wheel is correctly adjusted. Observe
the information relating to the correct driver's
seat position (Y page 102).
Additionally, you must ensure that an airbag can
deploy freely (Y page 44).
The airbag is supplementary to acorrectly fas-
tened seat belt. As an additional safety device,
the airbag increases the level of protection for
vehicle occupants in the event of an accident. If
the protection provided by the seat belt is suf-
ficient, the airbags do not deploy. Furthermore, in the event of an accident, only airbags which
provide greater protection in the given accident
situation deploy. However, seat belts and air-
bags generally do not protect against objects
penetrating the vehicle from the outside.
Information on how the restraint system oper-
ates can be found in "Deployment of the seat
belt tensioner and airbags" (Y page 52).
See "Children in the vehicle" for information on
infantsa nd children traveling with you in the
vehicle restraint systems for infantsa nd chil-
dren(Y page 55). Important safety notes
G
WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If modification of an airbag system is necessary to accommodate aperson with disabilities, con-
tact aqualified specialist workshop for details. Occupant safety
39Safety Z

Mercedes-Ben
zrecommends that you use a
Mercedes-Ben zService Centre for this. Restraint system warning lamp
The restraint systems functions are checked
after the ignition is switched on and at regular
intervals when the engine is running. This allows
malfunctions to be quickly identified.
The 6 restraint system warning lamp in the
instrumentc luster lights up when the ignition is
switched on. It goes out no later than afew sec-
onds after the vehicle is started. The compo-
nentsoft he restraint system are in operational
readiness.
Am alfunction has occurred if the 6restraint
system warning lamp:
R does not light up after the ignition is switched
on
R does not switch off after afew seconds when
the engine is running
R lights up again when the engine is running G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This can
effect belt tensionersora irbags, for example.
There is an increased risk of serious or even
fatal injuries.
Have the restraint system checked and
repaired immediately at aqualified specialist
workshop. PASSENGER AIR BAG indicator lamp PASSENGER AIR BAG ON indicator lamp
:and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the automatic deactivation system of the front-passenger front airbag.
The indicator lamps display the status of the
front-passenger front airbag.
R PASSENGER AIR BAG ON lights up: the front-
passenger front airbag is enabled. If, in the
event of an accident, all deployment criteria
are met, the front-passenger front airbag is
deployed.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
Depending on the person in the front-passenger seat, the front-passenger front airbag must
either be disabledore nabled; see the following

passenger front airbag is disabled. It is imper-
ative to observe the notes on the "Automatic front-passenger front airbag deactivation sys-
tem" (Y page 47) and on "Children in the
vehicle" (Y page 55).
R Children in aforward-facing child
restraint system: depending on the installed
child restraint system and the age and size of the child, the front-passenger front airbag is
either disabledore nabled. Therefore, it is
imperative to observe the notes on the "Auto-
matic front-passenger front airbag deactiva-
tion system" (Y page 47) and on "Children in
the vehicle" (Y page 55).
R All other persons: the PASSENGER AIR BAG
ON indicator lamp must be lit. The front-
passenger front airbag is enabled. Depending on the build of the person on the front-
passenger seat, the PASSENGER AIR BAG
OFF indicator lamp may light up. The front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident. In
this case, the front-passenger seat should not be used.
It is imperative to observe the notes on the
"Automatic front-passenger front airbag
deactivation system" (Y page 47) as well as
on "Seat belts" (Y page 41) and "Airbags"
(Y page 44). There you can also find infor-
mation on the correct seat position. 40

PASSENGER AIR BAG ON indicator lamp
; PASSENGER AIR BAG OFF indicator lamp
The indicator lamps show you whether the co-
driver's fron tairbag is disabled or enabled.
X Press the Start/Stop button onceort wice or
turn the key to position 1or 2in the ignition
lock.
The system carries out aself-diagnosis.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul- taneously for approximately six seconds.
The indicator lamps then show the status of the
co-driver's fron tairbag.
R PASSENGER AIR BAG ON is lit: the co-driver's
fron tairbag is enabled. If, in the case of an
accident, all deployment criteria are met, the
co-driver's fron tairbag is deployed.
R PASSENGER AIR BAG OFF is lit: the co-driv-
er's fron tairbag is disabled. It will then not be
deployed in the event of an accident.
If the status of the co-driver's fron tairbag
changes while the vehicle is in motion ,anairbag
display message appears in the instrument clus-
ter (Y page 263). When the co-driver's seat is
occupied, alway spay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status of the co-driver's fron tairbag both before and
during the journey.
If ap erson is occupying the co-driver's seat,
they must sit:
R with the seat belt fastened correctly
R in an almost upright position with their back
against the seat backrest
R with their feet restin gonthe floor, if possible If the co-driver does not observe this, the auto-
matic co-driver's fron tairbag deactivation sys-
tem may be influenced, for example if the co-
driver:
R transfers their weight by supportin gthem-
selves on avehicle armrest
R sits in such away that their weight is raised
from the seat cushion
This or similar behaviour can cause the co-driv-
er's fron tairbag to be deactivated when it
should not be. In this case, PASSENGER AIR BAG OFF indicator lamp lights up continuously. The
co-driver's fron tairbag is then not deployed in
an accident. G
WARNING
If the PASSENGER AIRBA GOFF indicator lamp
is lit, the front-passenger fron tairbag is disa-
bled. It will not be deployed in the event of an
acciden tand cannot perform its intended pro-
tective function .Aperson in the front-
passenger seat could then ,for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injur yore ven fatal injury.
When the front-passenger seat is occupied,
alway smake sure that:
R the classification of the person in the front-
passenger seat is correct and that the front-
passenger fron tairbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
fron tairbag is correct. G

Driving safety systems overview
In this section,y ou will find information about
the following driving safety systems:
R ABS (Anti-lock BrakingSystem)
(Y page 66)
R BAS ( Brake Assist System) (Y page 67)
R BAS PLUS with Cross-Traffic Assist ( Brake

Brake (Y page 75)
R STEERC ONTROL (Y page 77) Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther 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,f or vehicle speed, for braking in
good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and
weather condition sand maintain asafe distance
from the vehicle in front.D rive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tyres and the road
surface. Pay particular attention to the informa- tion regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and tyres" section (Y page 353).
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 effec-
tively as possible. ABS (Anti-loc
kBraking System)
General notes ABS regulates brake pressure in such
away that
the wheels do not lock when you brake. This
allowsy ou to continue steering the vehicle when
braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from aspeed of about 8km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you only brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristic smay be severely impaired. Addition-
ally,f urther driving safety systems are deac- 66
