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. Therefore, do not switch off
the engine when driving. Otherwise, the
safety systems in your vehicle may no longer
function correctly and, therefore, not protect
you or others as they are designed to do.
There is also a risk that you could lose control
of the vehicle and cause an accident as a
result. G
Risk of accident and injury
Work carried out incorrectly or modifications
to the vehicle, e.g. cables laid under the trim,
can impair the function of the safety systems.
The safety systems may no longer be able to
protect you or others as they are designed to
do. There is also a risk that you could lose
control of the vehicle and cause an accident
as a result.
Therefore always have work and modifica-
tions to the vehicle, such as installations or
conversions, carried out at a qualified spe-
cialist workshop. G
Risk of accident
If you drive over obstacles 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 and prevent the vehicle from bottom-
ing out when driving off-road. 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, the equipment could stop functioning. The electronic sys-
tems are networked via interfaces. Tampering
with these electronic systems could cause
malfunctions in systems which have not been
modified. Such malfunctions can seriously
compromise the vehicle's operating safety
and your own safety as well.
Therefore, have all work on and modifications
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.
Inform Mercedes-Benz as soon as possible
about any change in address or vehicle own-
ership. Correct use
Observe the following information when using
your vehicle:
R the safety notes in this manual
R the "Technical data" section in this manual
R national road traffic regulations
R national road traffic licensing regulations G
Risk of injury
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- 20

You must not tamper with electronic compo-
nents or 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 6 SRS warning lamp
R belt tensioners
R belt force limiters
R airbags
The 6 6 SRS warning lamp SRS functions are checked regularly when
you turn 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 not be
deployed in the event of an accident with
heavy braking.
A malfunction has occurred if the 6SRS
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 immediately
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.
Your vehicle has adaptive, dual stage front
airbags. When the first activation threshold is
reached, the front airbag is filled with enough
propellant gas to reduce the risk of injuries.
The front airbag is only fully inflated if a sec-
ond threshold is reached within a few milli-
seconds, due to the control unit having detec-
ted 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-
ess is pre-emptive in nature as the airbag
must be deployed during – and not at the end
of – the collision.
i Airbags are not deployed in all types of
accidents. They are controlled by complex
sensor technology and evaluation logic.
This process is pre-emptive in nature as
airbag deployment must take place during
the impact and must be adapted to provide Occupant safety

The brakes will work normally again when:
R you release the brake pedal
R no obstacle is detected in front of your
vehicle
R there is no longer any danger of a rear-end
collision
BAS PLUS is then deactivated.
At speeds up to approximately 70 km/h, BAS
PLUS can also detect stationary obstacles,
for example, stopped or parked vehicles.
Vehicles with COMAND and a navigation sys-
tem*: the radar sensor system is switched off
automatically in the vicinity of radio telescope
facilities (Y page 411).
For BAS PLUS to assist you when driving, the
radar sensor system must be switched on and
operational. You can check this by activating
Distronic Plus* (Y page 235) or via the
"Radar sensor" menu in the on-board com-
puter (Y page 226). 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 the sensors are cov-
ered
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example in
multi-storey garages
BAS PLUS does not react to people or ani-
mals, oncoming vehicles and crossing traffic.
BAS PLUS may not detect narrow vehicles
such as motorcycles and vehicles driving on
a different line.
Following a collision or crash-related damage
to the front end of the vehicle, have the con-
figuration and operation of the radar sensors
checked at a Mercedes-Benz Service Centre.
If BAS PLUS is not available due to a malfunc-
tion in the radar sensor system, the braking 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. If the
brakes are applied again, the brake lamps
light up continuously. The 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 (Y page 196). ESP
®
(Electronic Stability Program)
ESP ®
monitors driving stability and traction,
i.e. power transmission between tyres and
the road surface.
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 when braking.
When ESP ®
intervenes, the ÷warning
lamp flashes in the instrument cluster. G
Risk of accident
If the ÷ warning lamp in the instrument
cluster flashes, proceed as follows: 50

To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 224).
After activation, the Äsymbol is dis-
played on the left in the driver display.
Vehicles with COMAND and a navigation sys-
tem*: the radar sensor system is switched off
automatically in the vicinity of radio telescope
facilities (Y page 411).
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must be
switched on and operational.
PRE-SAFE ®
Brake does not always clearly
identify complex traffic situations properly.
You can terminate the intervention 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 gently
To end this you can either depress the accel-
erator pedal further, activate kickdown or
release the brake pedal.
The braking intervention 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 danger of a collision.
i While Distronic Plus is activated, PRE-
SAFE ®
Brake remains passive.
Following a collision or crash-related damage
to the front end of the vehicle, have the con-
figuration and operation of the radar sensors
checked. Choose a qualified specialist work-
shop for this which has the necessary spe-
cialist knowledge and tools for the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. Anti-theft systems

R Place DVDs back in their cases after use.
R Protect DVDs from heat and direct sunlight.
Map software copy protection Map software for COMAND is subject to a
charge. The map software has just one acti-
vation code which is usable in one vehicle
only, and is not transferable. You can obtain
the six digit activation code from your
Mercedes-Benz Service Centre. If you have
lost the activation code, or if COMAND does
not accept the activation code that you have
received, ask at your Mercedes-Benz Service
Centre.
Your vehicle is supplied with map software at
the factory. Depending on the country, the
map software for your region is either pre-
installed (Europe/USA), or the map software
is provided on a DVD (all other countries). You
do not require an activation code for the map
software that is provided with your vehicle. If the map software on your vehicle has been
installed at the factory and you wish to rein-
stall it, this also does not necessitate entry of
the activation code.
Installation process X

Risk of accident
If children are left unsupervised in the vehicle,
they could:
R open a door from the inside at any time,
even if it has been locked
R start the vehicle using a key 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. :

When unlocking, the turn signals flash once.
When locking, they flash three times.
When it is dark, the surround lighting also
comes on if it is activated in COMAND.
If you do not open either a door or the boot
lid after you have unlocked the vehicle, it will automatically relock after approximately 40
seconds.
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 door handles,
KEYLESS GO establishes a radio connection
between the vehicle and the key.
The distance to the vehicle's door handle
from which you wish to lock or unlock the
vehicle must not be greater than 1 m.
When starting the engine and whilst driving,
KEYLESS GO also checks whether a valid key
is in the vehicle by periodically establishing
radio contact. X
