PASSENGERA
IR BAG OFF indicator lamp :
shows you whether the front-passenger front airbag is disabled.
X Turn the key to position 1or 2in the ignition
lock or, on vehicles with KEYLESS-GO,
press the Start/Stop button once or twice. The system carries out aself-diagnosis.
The PASSENGERA IR BAG OFF indicator lamp
must light up for approximately six seconds.
If, after the system self-test, the
PASSENGER AIR BAG OFF indicator lamp:
R lights up ,the front-passenger fronta irbag
is disabled. It will then not be deployed in
the event of an accident.
R is not lit,t he sensor system did not detect
ac hild restraint system with transponder
for automatic child seat recognition. If, in
the case of an accident ,all deployment cri-
teria are met, the front-passenger fronta ir-
bag is deployed. G
WARNING
Electronic devices on the front-passenger
seat can affect the function of the automatic
child seat recognition, for example:
R laptop
R mobile phone
R transponder cards such as ski passes or
access passes
The front-passenger fronta irbag could deploy
unintentionally or not function as intended
during an accident .This poses an increased
risk of injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat. Be aware of the status of the front-passenger fronta irbag both before and
during the journey. Child restraint system on the front-
passenger seat
General notes Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you install achild restraint system on a
rear seat.
Vehicles with automatic child seat recogni-
tion on the front-passenger seat: if it is abso- lutely necessary to fit achild restraint system
to the front-passenger seat, alway sobserve
the information on "Automatic child seat rec-
ognition on the front-passenger seat"
(Y page 65).
You can thus avoid the risks that could arise
as aresult of:
R ac hild restraint system that is not detected
by the automatic child seat recognition
sensor system
R the unintentional disabling of the front-
passenger fronta irbag
R the unsuitable positionin gofthe child
restraint system, e.g. too close to the dash-
board Please observe the warning notice on the
front-passenger sun visor; see the illustra-
tion.

If it is absolutely necessary to fit arearward-
facing child restraint system to the front-
passenger seat, always make sure that the
front-passenger front airbag is disabled. Only if the PASSENGER AIR BAG OFF indicator
lamp is lit continuously (Y page 45) is the
front-passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 70) in addition to the child restraint
system manufacturer' sinstallation and oper-
ating instructions.
Forward-facing child restraint system If it is absolutely necessary to fit
aforward-
facing child restraint system to the front-
passenger seat, always move the front-
passenger seat as far back as possible. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the child
restraint system must, as far as possible, lie
flat against the backrest of the front-
passenger seat. The child restraint system
must not touch the roof or be put under strain by the head restraint .Adjust the angle of the
seat backrest and the head restraint position accordingly. Always make sure that the shoul-
der belt strap is correctly routed from the 68

WARNING
If ABS is faulty, the wheels coul dlock 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 dange rofskid-
ding and accidents.
Drive on carefully.H ave ABS checked imme-
diately at aqualified specialist workshop.
If ABS is malfunctioning, other systems,
including driving safety systems ,willa lso
become inoperative. Observe the information on the ABS warning lamp (Y page332) and
display messages which may be show ninthe
instrument cluster (Y page300).
ABS works from aspee dofa bout8km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you
only brake gently.
Brakes X
If ABS intervenes: continue to depress the
brake peda lwith force until the braking sit-
uation is over.
X To make afull brake application:
depress the brake peda lwith full force.
If ABS intervenes when braking, you willf eel a
pulsing in the brake pedal.
The pulsating brake peda lcan be an indica-
tion of hazardous road conditions; this serves
as areminde rtotake extra care while driving. BAS (Brake Assist System)
General notes BAS operates in emergency braking situa-
tions. If you depress the brake peda lquickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance. Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page77). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is arisk of accident.
In an emergency braking situation, depress
the brake peda lwith full force. ABS prevents
the wheels from locking.
Brakes X
Keep the brake peda ldepressed firmly until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes willf unction as usual once you
release the brake pedal. BAS is deactivated. BAS PLUS(
Brake Assist System
PLUS) with Cross-Traffic Assist
General notes i
Observe the "Important safety notes" sec-
tion (Y page77).
BAS PLUS is only available on vehicles with
the Driving Assistance package.
For BAS PLUS to assist you when driving, the
rada rsensor system and the camera system
must be operational.
With the help of asensor system and acam-
era system, BAS PLUS can detect obstacles:
R that are in the path of yourv ehiclefor an
extended period of time
R that cross the path of yourv ehicle
In addition, pedestrians in the path of your
vehicl ecan be detected.
BAS PLUS detects pedestrians using typical
characteristics such as the body contours
and posture of aperso nstanding upright.
If the rada rsensor system or the camera sys-
tem is malfunctioning, BAS PLUS functions
are restricted or no longer available.T he78

WARNING
BASP LUS cannot always clearly identify
objects and complex traffic situations.
In such cases, BASP LUS may:
R interven eunnecessarily
R not intervene
There is arisk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in anon-critical drivin gsituation. G
WARNING
BASP LUS does not react:
R to small people, e.g. children
R to animals
R to oncoming vehicles
R when cornering
As aresult, BASP LUS may not interven einall
critical situations. There is arisk of an acci-
dent.
Always pay careful attention to the traffic sit- uation and be ready to brake.
In the event of snowfall or heavy rain, detec-
tion can be impaired.
Detection by the radar senso rsystem is also
impaired in the event of:
R dirt on the sensors or obscured sensors
R interferenc ebyother radar sources
R strong radar reflections, for example, in
multi-storey car parks R
an arro wvehicle travelling in front, e.g. a
motorcycle
R av ehicle travelling in fron tonadifferent
line
R vehicles quickly movin gintot he radar sen-
sor system detection range
Detection by the camera system is also
impaired in the event of:
R dirt on the camera or if the camera is cov-
ered
R glare on the camera system, e.g. from the
sun being low in the sky
R darkness
R if:
- pedestrians move quickly, e.g. int othe
path of the vehicle
- the camera system no longer detects a
pedestrian as aperson due to special
clothing or other objects
- ap edestrian is concealed by other
objects
- the typical outline of aperson is not dis-
tinguishable from the background
Following damage to the fron tend of the vehi-
cle, have the radar senso rsettings and oper-
ation checked at aqualified specialist work-
shop. This also applies to collisions at slow
speeds where ther eisnovisible damage to
the fron tofthe vehicle.
Following damage to the windscreen, have
the configuration and operation of the cam-
era system checked at aqualified specialist
workshop.
Function To avoid
acollision, BASP LUS calculates the
