Operating safety
17Operating 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. Therefore, do not
switch off the engine when driving. Other-
wise, the safety systems in your vehicle
may no longer function correctly and
thereby not provide you or others with the
intended degree of protection. This also
increases the danger of your losing control
of your vehicle and thereby the risk of caus-
ing 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 functioning. The electronic systems are networked via inter-
faces. Tampering with these electronic sys-
tems could cause malfunctions in systems
which have not been modified. Such mal-
functions can seriously jeopardise the vehi-
cle’s operating safety and your own safety
as well.
Therefore have all work on and modifica-
tions to electronic components carried out
by a qualified 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. Introduction

Occupant safety
41deceleration force would normally be high
enough to trigger the systems, or they
could be triggered unintentionally. Never
carry out any modifications on the restraint
systems.
Never tamper with electronic components
and their software.
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 subjected
during an accident.
The SRS consists of:
R the 1 warning lamp
R belt tensioners
R belt force limiters
R airbags
The 1 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, the airbag con-
trol unit pre-emptively triggers the belt
tensioners in the first stage.
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.
Your vehicle has adaptive, dual stage front
airbags. When the first activation threshold
has been reached, the front airbag is filled
with enough propellant gas to minimise the
risk of injury. The front airbag is only fully
inflated if a second threshold is reached
within a few milliseconds, 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

Restoring the factory settings X
Press the kandj buttons simulta-
neously for approximately six seconds until
the battery check lamp flashes twice. KEYLESS GO key*
The optional equipment supplied with your
vehicle includes two KEYLESS GO keys. KEY-
LESS GO allows you to lock/unlock and start
the vehicle simply by carrying the KEYLESS
GO key with you. When you touch the surface
of the sensors on the vehicle's door handles,
KEYLESS GO establishes a radio connection
between the vehicle and the key.
When you touch the inner surface of the door
handle or press the button on the tailgate
handle (Estate), your vehicle unlocks cen-
trally if the factory settings have not been
changed:
R the doors
R the boot lid/tailgate
R the fuel filler flap
When starting the engine and whilst driving,
KEYLESS GO also checks whether a valid
KEYLESS GO key is in the vehicle by periodi-
cally establishing radio contact. G
Risk of accident
If children are left unsupervised in the vehi-
cle, they could open a door from the inside,
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 KEY-
LESS GO button on the gear selector lever.
They could endanger themselves and oth-
ers. Never leave children unsupervised in
the vehicle. 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
