2011 MERCEDES-BENZ CLS COUPE instrument cluster

Airbags and belt tensioners could fail to
deploy or be triggered in an accident despite
the deceleratio nforce 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. SRS (Supplemental Restraint System)
Introduction 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
effect of the forces to which occupants are
subjected during an accident.
SRS consists of:
R the 6 SRS warning lamp
R airbags
R airbag control unit (with crash sensors)
R belt tensioners
R belt force limiters
SRS warning lamp 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. G
Risk of injury
If SRS is malfunctioning, individual systems
may be activated unintentionally or may 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 6SRS
warning lamp does not go out after a few
seconds.
R the engine is running and the 6SRS
warning lamp lights up again.
In this case, have SRS checked immediately
at a qualified specialist workshop. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose.
In particular, work relevant to safety or on
safety-related systems must be carried out at
a qualified specialist workshop.
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. When the first deployment
threshold is reached, the front airbag is filled
with enough propellant gas to reduce the risk
of injuries. The front airbag is fully deployed
if a second deployment threshold is exceeded
within a few milliseconds. Occupant safety

The belt strap is tightened slightly when:
R you engage the belt tongue in the belt
buckle and you then turn the key to position
2in the ignition lock.
R the key is in position 2in the ignition lock
and you then engage the belt tongue in the

The seat-belt adjustmen twill apply a certain
tightening force if any slack is detected
between the occupant and the seat belt. Do
not hold on to the seat belt tightly while it is
adjusting. You can switch the seat-belt
adjustment on and off in the on-board com-
puter (Y page 211).

Belt warning for driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts .Itmay light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the fron tpassenger have fastened their seat
belt .Ift he vehicle is stationary and a door is
opened, the 7seat belt warning lamp
goes out and the warning tone ceases.
For certain countries only: regardless of
whether the driver or the front passenger
have fastened their seat belts, the 7seat
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.
i For more information on the 7seat
belt warning lamp, see "Indicator and warn-
ing lamps in the instrumentc luster, seat
belt" (Y page 239).

.
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. On vehicles with 4MATIC, more drive
torque is also transferred to the wheel or
wheels with traction.
Traction control remains active if you deacti-
vate ESP ®

Risk of accident
If EBD has 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. ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (Y page 165) and

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

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
