components can be largely prevented.
Diagnostics connection
G
WARNING
If you connect equipment to the diagnostics
connection, it can affect the operation of the
vehicle systems .This can impair the operating
safety of your vehicle while driving. There is a
risk of accident.
Do not connect any equipment to the diag-
nostics connection. G
WARNING
Loose equipment or equipment cables that
are connected to the diagnostics connection
can obstruct the area around the pedals. The
equipment or the cables could get between
the pedals in the event of sudden braking or
acceleration. As a result, the movement of the
pedals may be impaired. There is a risk of
accident.
Do not attach any equipment or cables in the
driver footwell.
! If the engine is switched off and equip-
ment on the diagnostics connection is
used, the starter battery may discharge.
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
Connecting equipment to the diagnostics
connection can, for example, lead to emis-
sions monitoring information being reset.
This may lead to the vehicle failing to meet
the requirements of the next emissions test
during the main inspection. Qualified specialist workshop
Aq ualified specialist workshop has the nec-
essary specialist knowledge, tools and quali-
fications to correctl ycarry out the work required on your vehicle
.This is especially the
case for work relevant to safety.
Observe the information in the Service Book-
let.
Always have the following work carried out at
a qualified specialist workshop:
R work relevant to safety

Mercedes-Ben zrecommends that you use a
Mercedes-Benz Service Centre. 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-
BenzS ervice Centre, it is possible that your
vehicle is not registered in your name with
Mercedes-Benz. Mercedes-Benz can only
infor myou about vehicle checks if it has your
registration data.
It is advisable to register your vehicle with a
Mercedes-Benz Service Centre.

WARNING
Various warning stickers are affixed to your
vehicle. Their purpose is to draw your atten-
tion, and the attention of others, to various
dangers. Therefore, do not remove any warn-
ing stickers unless the sticker clearly states
that you may do so. Introduction

tentionally. For this reason, never make any
modifications to the restraint systems.
Therefore, you must not tampe rwith elec-
tronic components or their software. SRS (Supplemental Restraint System)
Introduction 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 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 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
WARNING
If SRS is malfunctioning, individual systems
may be triggered unintentionally or might 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.
Triggering of belt tensioners, belt force
limiters and airbags During the firs
tstage of a collision, the airbag
control uni tevaluates important physical
data relating to vehicle deceleratio noraccel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control uni tpre-emptively triggers the
beltt ensioners in the first stage.
i The fron tbelt 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 fron tairbags 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. In the firs tdeployment stage,
the fron tairbag is filled with enough propel-
lant gas to reduce the risk of injuries. The
front airbag is fully deployed if a second
deploymen tthreshold is exceeded within a
few milliseconds.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration or acceleration of the
vehicle. This process is pre-emptive in nature.
The triggering process must take place in
good time at the start of the collision.
i Airbags are not deployed in all types of
accidents. Also, not all airbags are
deployed together in an accident. The dif-
ferent airbag systems work independently
of each other. Occupant safety
43Safety Z

In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else cover-
ing the sensors
R snow or heavy rain
R interference by other radars ources
R the possibility of strong radar reflections,
for example, in multi-storey car parks
R a narrow vehicle travelling in front, e.g. a
motorbike
R a vehicle travelling in front on a different
line G
WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, PRE-SAFE ®
Brake may not give
warnings or intervene in critical situations.
There is a risk of an accident .Always pay
careful attention to the traffic situation and be
ready to brake.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a col-
lision, you must apply the brakes yourself.
X To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 241).
The Ä symbol appears in the multifunc-
tion display as long as the HOL Dfunction
is not activated (Y page 194).
On vehicles with parking guidance, the
Ä symbol is displayed when Pis
engaged or you are driving faste rthan
35 km/h.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities (Y page 398).
Vehicles without COMAND and a navigation
system and vehicles for Australia: the radar
sensor system and on-board computer must be switched off in the vicinity of radio tele-
scope facilities (Y page 247).
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must be
switched on (Y page 247) and be opera-
tional.
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensors checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle. Anti-theft systems
Immobiliser
The immobiliser prevents your vehicle from
being started without the correct key.
X To activate with the key: remove the key
from the ignition lock.
X To activate with KEYLESS-GO: switch the
ignition off and open the driver's door.
X To deactivate: switch on the ignition.
i The immobiliser is always deactivated

alarm system is primed and you open:
R a door
R the vehicle with the emergency key ele-
ment
R the boot lid/tailgate
R the bonnet
The alarm is not switched off, even if you
close the open door that has triggered it, for
example. Anti-theft systems
77Safety Z

If you activate the acoustic locking confirma-
tion function you will hear the following,
depending on the date of production of the
vehicle:
R an acoustic signal when locking
or
R one acoustic signal when unlocking and
three when locking
The audible signal can be activated and deac-
tivated using the on-board computer
(Y page 247).
X To unlockc entrally:press the%but-
ton.
If you do not open th evehicle within approx-
imately 40 seconds of unlocking:
R the vehicle is locked again.
R the anti-thef tsystem is primed again.
X To lock centrally: press the&button. KEYLESS-GO
Important notes on the use of KEYLESS-
GO R
Do no tkeep the KEYLESS-GO key together
with:
- electronic devices, e.g. a mobile phone
or another key
- metallic objects, e.g. coins or metal foil
This can affect the functionality of KEY-
LESS-GO.
R Bear in mind that the engine can be started
by any of the vehicle occupants if there is
a KEYLESS-GO key in the vehicle.
Locking and unlocking centrally You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry
the key with you. You can combine the KEY-
LESS-GO functions with those of a conven-
tional key, e.g. using KEYLESS-GO to unlock
and pressing the &button to lock. When locking or unlocking with KEYLESS-GO,
the distance between the key and the corre-
sponding door handle must not be greater
than 1 m.
KEYLESS-GO checks whether a valid key is in
the vehicle by periodically establishing a radio
connection between the vehicle and the key.
This happens:
R
when the external door handles are
touched
R when starting the engine
R while the vehicle is in motion X
To unlock the vehicle: touch the inner
surface of the door handle.
X To lock the vehicle: touch sensor sur-
face :.
X Convenience closing feature: touch
recessed sensor surface ;for an exten-
ded period (Y page 97).
If you pull on the handle of the boot lid/tail-
gate, only the boot/luggage compartment of
the vehicle is unlocked.
If the vehicle has been parked for a long time,
the sensor surfaces are deactivated automat-
ically. In order to unlock the door, pull the
door handle. In order to reactivate the sensor
surface, switch the ignition on again. Changing the settings of the locking

Important safety notes
G
WARNING
Only for the United Kingdom: if the vehicle
has been locked with the key, the double lock
function is activated as standard. It is then not
possible to open the doors from inside the
vehicle.
Therefore, do not leave any people behind in
the vehicle, particularly children, elderly peo-
ple or people in need of special assistance if
the vehicle has been locked with the key. As
a result, they may not be able to free them-
selves in the event of an emergency. As a
result, they could be seriously or even fatally injured by prolonged exposure to extremely
high or low temperatures, for example. In this
case, rescuing people from outside the vehi-
cle is difficult.
Deactivate the interior motion sensor before
you lock the vehicle with the key. The doors
can then be opened from the inside after the
vehicle has been locked from the outside with
the key. G
