the vehicle occupants on the side of the vehi-
cle on which the impact occurs.
The windowbags are integrated into the side
of the roo
fframe and deploy in the area
extending from the front door (A-pillar) to the
rear door (C-pillar). Windowbags
:are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleratio noraccelera-
tion, e.g. in a side impact
R regardless of whethe rthe front-passenger
seat is occupied
R independently of seat belt use
R if the vehicle overturns and the system
determines that windowbag deployment
can offer additional protection to that pro-
vided by the seat belt
R independently of the front airbags PRE-SAFE
®
(preventative occupant
protection)
PRE-SAFE ®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes:
R in emergency braking situations, e.g. if BAS
is activated or intervenes powerfully in vehicles with DISTRONIC PLUS, BAS PLUS
or PRE-SAFE ®
Brake
R if the radar sensor system detects an immi-
nent danger of collision in certain situa-
tions (on vehicles with DISTRONIC PLUS)
R in critical situations involving driving
dynamics, e.g. if the vehicle oversteers or
understeers significantly due to physical
limits being exceeded or if the vehicle
swerves to avoid an obstacle at a speed of
over 140 km/h.
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R vehicles with the memory function: under
accident conditions, it adjusts the front-
passenger seat if it is in an unfavourable
position.
R vehicles with a multicontour seat or an
active multicontour seat: the air pressure
in the side bolsters on the seat cushion and
the side bolsters on the backrest is
increased.
R if the vehicle skids, the sliding sunroof/
panorama sliding sunroof and the side win-
dows are closed so that only a small gap
remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. The air pressure in the
side bolsters on the multicontour seat/active
multicontour seat is reduced again. All set-
tings made by PRE-SAFE ®
can then be
reversed.
If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism releases. G
Risk of injury
When adjusting the seat, make sure that
nobody can become trapped. 40
Occupant safetySafety
This function will issue a warning at speeds of
around 30 km/h or more if:
R
for a period of several seconds, the dis-
tance to the vehicle in fronti s too short for
the speed at which you are travelling. The
· distance warning lamp in the instru-
ment cluster will light up.
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 instrument cluster.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning. G
Risk of accident
Pay particular attention to the traffic condi-
tions if the ·distance warning lamp in the
instrument cluster lights up or an intermittent
warning tone sounds. If necessary, brake or
manoeuvre to avoid an obstacle.
If the driver and passengers have fastened
their seat belts, PRE-SAFE ®
Brake can also
can also perform the following at speeds of
above approximately 30 km/h:
R brake the vehicle automatically from a
speed of up to approximately 200 km/h
R trigger preventative passenger protection
measures (PRE-SAFE ®
) G
Risk of accident
PRE-SAFE ®
Brake is only an aid to assist you
when driving. You are responsible for main-
taining a safe distance from other vehicles,
the vehicle's speed and for braking in good
time. Always pay attention to the traffic con-
ditions. Otherwise, you may recognise dan-
gers too late, cause an accident and injure
yourselfa nd others.
With the help of the rada rsensor system,
PRE-SAFE ®
Brake can detect obstacles that
are in front of your vehicle for an extended
period of time. If you approach an obstacle
and PRE-SAFE ®
Brake detects a risk of a col-
lision, the system will initially alert you both visually and acoustically. If you do not brake
or steer, the vehicle will at first automatically
brake slightly. In the event of an increased
risk of a collision, PRE-SAFE
®
is activated
(Y page 40). If the risk of collision remains
and you do not brake, take evasive action or
accelerate significantly, the vehicle may per-
form automatic emergency braking. G
Risk of accident
Only clearly detected obstacles will trigger a
warning and initiate braking assistance by
PRE-SAFE ®
Brake.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or the sensors are cov-
ered
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
PRE-SAFE ®
Brake does not react to persons,
animals, oncoming vehicles, crossing traffic
or when cornering.
PRE-SAFE ®
Brake may not detect narrow
vehicles such as motorcycles and vehicles
driving on a different line. G
Risk of accident
Depending on the current speed, PRE-SAFE ®
Brake decelerates your vehicle by up to
4 m/s 2
before performing possible emer-
gency braking. This is equivalent to approx-
imately 40 % of the maximum braking power
of the vehicle. You must additionally apply the
brakes yourself in order to preven tacollision
or minimis ean impact. Automatic emergency
braking is not performed until immediately
prior to an accident in the event that you are
unable to avoid one by, for instance, taking
evasive action.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a col-
lision, you must apply the brakes yourself. 62

R you are as far away from the driver's air-
bag as possible.
R you are sitting in a normal upright posi-
tion.
R you can fasten the seat belt properly.
R you have moved the backrest to an
almost vertical position. R
you have set the seat cushion angle so
that your thighs are gently supported.
R you can depress the pedals properly.
X Check whether the head restraint is adjus-
ted properly (Y page 86).
When doing so, make sure that you have
adjusted the head restraint so that the back
of your head is supported at eye level by
the centre of the head restraint.
Observe the safety guidelines on
(Y page 90).
X Check whether steering wheel :is adjus-
ted properly.

Important safety notes
G
Risk of injury
The seats can still be adjusted when there is
no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could adjust the seats and
become trapped. G
Risk of accident
Only adjust the driver's seat when the vehicle
is stationary. You will otherwise be distracted
from the road and traffic conditions and you
could lose control of the vehicle as a result of
the seat moving. This could cause an acci-
dent. G
Risk of injury
Make sure that nobody can become trapped
when adjusting the seats.
Observe the notes on airbags.
Secure children as recommended; see the
"Children in the vehicle" section. G
Risk of injury
Make sure that the back of your head is sup-
ported at eye level by the central area of the
head restraint .Ifyour head is not supported
correctly by the head restraint, you could suf-
fer a severe neck injury in the event of an
accident .Never drive if the head restraints are
not engaged and set correctly. G
Risk of injury
Occupants should only travel sitting on seats
which have the head restraints fitted. On a
seat which is occupied, move the head
restraint into the upright position .This
reduces the risk of injury to the passenger in
the event of an accident. !
To avoid damage to the seats and the seat
heating, observe the following information:
R do not spill any liquids on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not to be used to dry
the seats.
R clean the seat covers as recommended;
see the "Interior care" section.
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools.
The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating mate-
rials, e.g. blankets, coats, bags, seat cov-
ers, child seats or booster seats.
! When you move the seats, make sure that
there are no objects in the footwell or
behind the seats. Otherwise, you could
damage the seats and the objects.
i The head restraints in the front seats are
fitted with the NECK-PRO system
(Y page 41). For this reason, it is not pos-
sible to remove the head restraints from
the front seats.
Please contact a Mercedes-Benz Service
Centre for more information.

Adaptive Highbeam Assist G
Risk of accident
Adaptive Highbeam Assist is only an aid
designed to assist driving. The drive ris
responsible for adjusting the vehicle's lighting
to the prevailing light, visio nand traffic con-
ditions. The system may be impaired or deactivated:
R if there is poor visibility, e.g .due to snow,
rain, fog or spray
R if the area of the windscree naround the
optical sensor is dirty, misted up or covered
up, e.g. by a sticker
The system may not recognise the following
road users:
R road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whose lighting is not clearly visi-
ble, e.g. road users behind a crash barrier
R on rare occasions: road users that have
lights that may be recognised too late or not
at all
The automatic main-bea mheadlamps will not
be deactivated, or they may be activated
despite road users travelling in fron tofor
approaching the vehicle.
Thus, you could cause an acciden tand injure
yoursel fand others. Alway sobserve traffic
conditions and, if necessary, dip the lights
manually.
You can use this function to set the head-
lamps to change between dipped beam and
main beam automatically. The system recog-
nises vehicles with their lights on, either
approaching from the opposite direction or
travelling in fron tofyour vehicle, and conse-
quently switches the headlamps from main
beam to dipped beam.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the main-beam headlamps.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. 100
