tofyour vehicle. Should
you have any questions concerning equip-
ment and operation, please consult a
Mercedes-Benz Service Centre. Operating safety
Safety notes
G
Risk of accident and injury
Always have work on the vehicle carried out
by a qualified specialist workshop. In particu-
lar, work relevant to safety or on safety-rela-
ted systems as well as maintenance work
must be carried out at aqualified specialist
workshop. The workshop must have the nec-
essary specialist knowledge and tools to carry
out the work required. Mercedes-Benz rec-
ommends 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 vehicle may not
function correctly and as a result will no lon-
ge rp rotect you and other persons as inten-
ded. In addition, there is a risk that you may
lose control of yourv ehicle and thus cause an
accident. G
Risk of accident and injury
Work carried out incorrectly, or alterations
made to the vehicle, e.g. re-routing of cables
under coverings, could cause the safety sys-
tems of your vehicle to stop working properly.
The safety systems would thus no longer pro-
tecty ou and other persons as intended. In
addition, there is a risk that you may lose con-
trol of your vehicle and thus cause an acci-
dent.
All work and alterations to the vehicle, e.g.
installations or modifications, should there-
fore be carried out at aqualified specialist
workshop. G
Ris
kofa ccident
If you drive ove robstacles at high speed or if
the vehicle bottoms out in rough terrain, it
could cause heavy impacts to the vehicle
underbody, tyres or wheels. This could cause
your vehicle to be damaged, which in turn
might lead to an accident. This also applies to
vehicles which are equipped with underbody
protection.
You should therefore drive over obstacles
slowly. Preven tthe vehicle from bottoming
out when driving off-road and if necessary,
have your vehicle inspected at a qualified spe-
cialist workshop. G
Risk of accident
If work on electronic equipment and its soft-
ware is carried out incorrectly, this equipment
could stop working. The electronic systems
are networked via interfaces. Tampering with
these electronic systems could cause mal-
functions in systems which have not been
modified. Malfunctions such as these can
seriously jeopardise the vehicle's operating
safety and therefore your own safety.
You should therefore have all work and mod-
ifications 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. 20
Introduction

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

force to a level suitable for the traffic condi-
tions.
If BAS PLUS demands particularly high brak-
ing force, PRE-SAFE
®
is activated simultane-
ously.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if:
R you release the brake pedal.
R no obstacle is detected in front of your
vehicle.
R there is no longe rany dange rofarear-end
collision.
BAS PLUS is then deactivated.
At speeds up to approximately 70 km/h, BAS
PLUS may also detect stationary obstacles,
for example, stopped or parked vehicles.
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 210).
For BAS PLUS to assist you when driving, the
rada rsensor system must be switched on and
operational. You can chec kthis by activating
DISTRONIC PLUS(Y page 154) or via the
"radars ensor" function in the on-board com-
puter (Y page 210). G
Risk of accident
Only clearly identified obstacles will initiate
braking assistance by BAS PLUS.
In particular, the detection of obstacles can
be restricted if there is:
R dirt on the sensors or anything else cover-
ing the sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example in
multi-storey car parks
BAS PLUS does not react to people or ani-
mals, oncoming vehicles and crossing traffic,
or when cornering. BAS PLUS may not detect narrow vehicles
such as motorcycles and vehicles driving on
a different line.
Following a collision or accident-related dam-
age to the fron tend of the vehicle, have the
configuratio nand operatio nofthe radar sen-
sors checked at a Mercedes-Benz Service
Centre.
If BAS PLUS is not available due to a malfunc-
tion in the radar sensor system, the brake
system remains available with full brake
boosting effect and BAS. Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS
or BAS PLUS, the brake lamps flash rapidly.
In this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically .Ifthe
brakes are applied again, the brake lamps
light up continuously.T he hazard warning
lamps switch off automatically if you travel
faster than 10 km/h .You can also switch off
the hazard warning lamps using the hazard
warning switch button . ESP
®
(Electronic Stability Program)
Important safety notes If ESP
®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking. 58
Driving safety systemsSafety

At speeds up to approximately 70 km/h,
PRE-SAFE ®
Brake may also detect stationary
obstacles, for example stoppe dorparked
vehicles. G
Ris
kofa ccident
If, in a critical driving situation, you do not
receive a visual and acoustic warning:
R PRE-SAFE ®
Brake did no tdetec tthe risk of
a collision
R PRE-SAFE ®
Brake is switched off
R PRE-SAFE ®
Brake has failed
You must then brake to avoid a collision.
X To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 204).
After activation, the Äsymbol is dis-
played on the left in the instrumentc luster.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities ( Ypage 327).
Vehicles without COMAND and navigation,
and vehicles for Australia: near radio tele-
scope installations, the radar sensor system
must be switched off with the on-board com-
puter (Y page 210).
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must be
switched on (Y page 210) and operational.
PRE-SAFE ®
Brake does not always detect
complex traffic situations properly. You can
terminate the braking action of PRE-SAFE ®
Brake in a non-critical driving situation at any
time if:
R an acoustic and visual warning occurs.
R the vehicle brakes.
To end this, you can either depress the accel-
erator pedal further, activate kickdown or
release the brake pedal. The braking action of PRE-SAFE
®
Brake is
ended automatically if:
R you manoeuvre to avoid the obstacle.
R you drive slower than approximately
15 km/h.
R there is no longer an obstacle detected in
front of your vehicle.
R there is no longer any dange rofacollision.
Following a collisio norcollision-related dam-
age to the front end of the vehicle, have the
configuration and operation of the radar sen-
sors checked. Choose a qualified specialist
workshop which has the necessary specialist
knowledge and tools for the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. Anti-theft systems
Immobiliser
The immobiliser prevents your vehicle from
being started without the correc tkey.
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
when you start the engine. ATA (Anti-Theft Alarm system)
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
The alarm is not switched off, even if you
close the open door that has triggered it, for
example. Anti-theft systems
63Safety Z

If you do not open
adoor or the boot lid within
approximately 40 seconds of unlocking the
vehicle:
R the vehicle is locked again.
R the anti-theft system is primed again.
X To lock centrally: press the&button. KEYLESS-GO
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry
the key with you. When you touch the surface
of the sensors on the vehicle's outside door
handles, KEYLESS-GO establishes a radio
connection between the vehicle and the key.
The distance from the door handle with which
you wish to lock or unlock the vehicle must
not be greater than 1 m.
When the engine is started and whilst you are
driving, KEYLESS-GO also checks whether a
valid key is in the vehicle by periodically
establishing radio contact. X
To unlock the vehicle: touch the inner
surface of the door handle.
X To lock the vehicle: touch sensor sur-
face :.
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 setting of the locking
system in such a way that only the driver's
door and the fuel filler flap are unlocked. This
is useful if you frequently travel on your own.
X To change the setting: press and hold down
the % and& buttons simultaneously
for approximately six seconds until battery
check lamp (Y page 70) flashes twice.
The key now functions as follows:
X To unlock the driver's door: press the

Problem Possible causes/consequences and
M Solutions
The engine cannot be
started using the key. The on-board voltage is too low.
X
Switch off non-essential consumers, e.g. seat heating or interior
lighting, and try to start the engine again.
If this does not work:
X Check the starter battery and charge it if necessary
(Y page 290).
or
X Jump-start the vehicle (Y page 294).
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
Risk of injury
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 requiring 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. They
could be seriously or even fatally injured by
prolonged exposure to extremely high or low
temperatures, for example. In this case, res-
cuing people from outside the vehicle is diffi-
cult.
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.
If the vehicle has been locked with KEYLESS-
GO, the doors can be opened from inside the
vehicle.
G
Risk of accident
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 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. Doors
