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 nex temissions 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

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.

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. 22
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 belt tensioners can only be triggered
if the seat belt tongues 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

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 ris kofanaccident. Always pay
careful attention to the traffi csituation 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 189).
The Ä symbol appears in the multifunc-
tion display as long as the HOL Dfunction
is not activated (Y page 165).
On vehicles with parking guidance, the
Ä symbol is displayed when Pis
engaged or you are driving faste rthan
35 km/h.
Vehicles with COMAND and navigation sys-
tem: the radar sensor system is switched off
automatically in the vicinity of radio telescope
facilities (Y page 312).
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 194).
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must be
switched on (Y page 194) 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

Av isual and audible alarm is triggered if the
alarm system is primed and you open:
R a door
R the vehicle with the emergency key ele-
ment
R the boot lid
R the bonnet
R the glove compartment
R the stowage space under the armrest
The alarm is not switched off, even if you
close the open door that has triggered it, for
example. Anti-theft systems
61Safety Z

When it is dark, the surround lighting also
comes on if it is activated in the on-board
computer (Y page 192).
You can also set an audible signal to confirm
that the vehicle has been locked. The audible
signal can be activated and deactivated using
the on-board computer (Y page 193).
X To unlock centrally: press the%but-
ton.
If you do not open the vehicle within approx-
imately 40 seconds of unlocking:
R the vehicle is locked again.
R the anti-theft system is primed again.
X To lock centrally: press the&button. KEYLESS-GO
Important notes on the use of KEYLESS-
GO R
Do not keep 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 77).
If you pull on the handle of the boot lid, only
the boot of the vehicle is unlocked. Changing the settings of the locking
system
You can change the settings of the locking
system so that when unlocking, only the driv-
er's door, the lockable stowage compart-
ments in the vehicle interior and the fuel filler
flap are unlocked. This is useful if you fre-
quently travel on your own.
X To change the setting: press and hold
down the %and& buttons simulta-
neously for approximately six seconds until
the battery check lamp flashes twice
(Y page 69). Key

(Y page 273).
or
X Jump-start the vehicle (Y page 277).
or
X Consult a qualified specialist workshop. The engine cannot be
started using KEYLESS-
GO. The key is in the
vehicle. Ad
oor is open. Therefore, the key cannot be detected as easily.
X Close the door and try to start the vehicle again. There is interference from a powerful source of radio waves.
X
Start your vehicle with the key in the ignition lock. Doors
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
WARNING
If children are left unsupervised in the vehicle,
they could:
R open a door from inside the vehicle at any
time, even if it has been locked
R start the vehicle using akey which has been
left in the vehicle
R release the electric parking brake
They could thereby endanger themselves and
others. Never leave children unsupervised in
the vehicle. Always take the key with you
when leaving the vehicle, even if you are only
leaving it for a short time. Unlocking and opening the doors
from the inside
For all countries except the United King-
dom: you can open a door from inside the
vehicle even if it has been locked.
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 Doors
