Operating safety
16 Operating safety
Safety notes
G
Risk of accident and injury
All work on the vehicle and, in particular,
work relevant to safety or on safety-related
systems must be carried out at a qualified
specialist workshop. The specialist work-
shop must have the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends
that you use a Mercedes-Benz Service
Centre for this purpose. G
Risk of accident and injury
Some safety systems only function when
the
engine is running. You should therefore
never switch off the engine when driving.
Otherwise the safety systems of your vehi-
cle may no longer protect you and other
persons as intended. In addition, there is
the danger that you may lose control of your
vehicle and thus cause an accident. G
Risk of accident and injury
Work carried out incorrectly, or alterations
made
to the vehicle, e.g. rerouting of cables
under coverings, could cause the safety
systems of your vehicle to stop working properly. The safety systems would thus no
longer protect you and other persons as
intended. In addition, there is the danger
that you may lose control of your vehicle
and thus cause an accident.
All

work and alterations to the vehicle, e.g.
installations or modifications, should there-
fore be carried out at a qualified specialist
workshop. G
Risk of accident
A heavy impact to the underbody, tyres or
wheels,
for example when bottoming out on
rough terrain or driving over an obstacle at
high speed, could damage your vehicle. As
a result, you could cause an accident. This
also applies to vehicles which are equipped
with underbody protection.
For this reason, drive slowly over obstacles,
avoid bottoming out the vehicle in rough
terrain and, if necessary, have your vehicle
checked at a qualified specialist workshop. G
Risk of accident
If work on electronic equipment and its
software is carried out incorrectly, this
equipment could stop working. The elec-
tronic systems are networked via interfa-
ces. Tampering with these electronic sys- tems could cause malfunctions in systems
which have not been modified. Malfunc-
tions such as these can seriously jeopard-
ise the vehicle's operating safety and
therefore your own safety.
You should thus have all work and modifi-
cations to electronic components carried
out at a qualified specialist workshop.
Vehicle registration
Mercedes-Benz may ask its Service Centres
to carry out technical inspections on certain
vehicles to improve their quality or safety.
If you did not purchase your vehicle from an
authorised specialist dealer and your vehicle
has never been inspected at a Mercedes-
Benz Service Centre, it is possible that your
vehicle is not registered in your name with
Mercedes-Benz. Mercedes-Benz can only
inform
you about vehicle checks if it has your
registration data.
It is advisable to register your vehicle with a
Mercedes-Benz Service Centre.
Inform Mercedes-Benz as soon as possible
about any change in address or vehicle own-
ership. Introduction

Occupant safety
43In particular, work relevant to safety or on
safety-related
systems must be carried out
at a qualified specialist workshop. If this
work is not carried out correctly, the oper-
ating safety of your vehicle may be affec-
ted. There is a risk of an accident and injury. SRS (Supplemental Restraint System)
The SRS reduces the risk of occupants com-
ing into contact with the vehicle's interior in
the event of an accident. It can also reduce
the forces to which occupants are exposed
during an accident.
The SRS consists of:
R 1 warning lamp
R belt tensioners
R belt force limiters
R Airbags
1 warning lamp The SRS functions are checked regularly
when you turn on the ignition and when the
engine

is running. Malfunctions can therefore
be detected in good time. The 1 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 not be
triggered in the event of an accident with
heavy braking.
A malfunction has occurred if the 1
warning lamp:
R does

not light up when you switch on the
ignition
R does not go out after the engine has been
running for a few seconds
R lights up again once the engine is running
In this case, have SRS checked immedi-
ately at a qualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags In the event of a collision, the sensor in the
airbag

control unit evaluates important phys-
ical data such as duration, direction and force
of the vehicle deceleration or acceleration.
Based on the evaluation of this data and depending on the vehicle's rate of longitudi-
nal deceleration in a collision, in the first
stage the airbag control unit pre-emptively
triggers the belt tensioners.
i
The

front belt tensioners can only be trig-
gered if the belt tongue is correctly
engaged in the seat belt buckle.
The front airbags are only deployed if there is
an even higher rate of vehicle deceleration in
a longitudinal direction.
Vehicles fitted with adaptive, dual-stage front
airbags: when the first deployment threshold
is reached, the front airbag is filled with
enough gas to reduce the risk of injuries. The
front airbag is only fully inflated if a second
threshold is reached within a few millisec-
onds due to the control unit having detected
further deceleration.
Criteria for triggering belt tensioners and
airbags
In the first stage of a collision, the airbag con-
trol unit evaluates the duration and direction
of vehicle acceleration or deceleration in
order to determine whether it is necessary to
trigger the belt tensioner and/or airbag.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration of the vehicle. This proc- Safety

If you are carrying the KEYLESS GO key on
your person, you can use the KEYLESS GO
functions of your vehicle. The KEYLESS GO
key should not be more than one metre away
from the vehicle. However, you can also use
the KEYLESS GO key like a normal key with
remote control.
When you pull the door handle, the following
unlock centrally if the factory settings have
not been changed:
R the doors
R the boot lid
R the fuel filler flap G
Risk of accident
Never leave children unsupervised in the
vehicle. They could open a door from the
inside at any time, even if it has been
locked. Or they could start the vehicle if a
valid KEYLESS GO key is in the vehicle and
they press the KEYLESS GO button on the
gear selector lever. They could endanger
themselves and others. Switch off the
engine and take the KEYLESS GO key with
you, even if you are only leaving the vehicle
for a short time. 1
