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

R
Under no circumstances should you deac-
tivate ESP ®
.
R When pulling away, only depress the accel-
erator pedal as far as is necessary.
R Adapt your driving style to the prevailing
road and weather conditions.
The vehicle may otherwise begin to skid.
If you drive too fast, ESP ®
cannot reduce the
risk of an accident. ESP ®
cannot override the
laws of physics.
! If the vehicle is to be towed with the front
or rear axle raised, the ignition must be
switched off (key in position 0or 1in the
ignition lock). Application of the brakes by
ESP ®
could otherwise destroy the brake
system on the front or rear axle.
! Vehicles with 4MATIC* may not be towed
with the front or rear axle raised.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS (Electronic Traction Support) Traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example, if the road surface is slippery on one
side.
Traction control remains active when you
deactivate ESP ®
. G
Risk of accident
Traction control cannot reduce the risk of an
accident if you drive too fast. Traction control
cannot override the laws of physics.
Activating/deactivating ESP ®ESP
®
is activated automatically when the
engine is running. It may be best to deactivate ESP
®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilise the vehicle
if the vehicle starts to skid or a wheel starts
to spin.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R engine torque is not limited and the drive
wheels are able to spin. The spinning
wheels produce a cutting effect for better
traction.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
i If ESP ®
is deactivated and one or more
wheels start to spin, the ÷warning lamp
in the instrument cluster flashes. In such
situations, ESP ®
will not stabilise the vehi-
cle.
X To deactivate: (Ypage 224).
The å warning lamp in the instrument
cluster lights up. G
Risk of accident
If the å warning lamp in the instrument
cluster lights up when the engine is running,
ESP ®
is deactivated or is unavailable due to a
malfunction. The risk that your vehicle may
start to skid then increases in certain situa-
tions.
Always adapt your driving style to the prevail-
ing road and weather conditions. Driving safety systems

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

ing message.
X Select OK.
COMAND calculates a new route. Only
those options which can be implemented
are considered. Installing map software
The digital maps generated by the map soft-
ware become outdated in the same way as
conventional road maps. Optimum route
guidance can only be provided by the naviga-
tion system in conjunction with the most up-
to-date map software. Information about new
map software versions can be obtained from
a Mercedes-Benz Service Centre.
You can install new map software, which may
consist of one of more DVDs (depending on
the scope), yourself.
The installation process can take between
10 and 120 minutes, depending on the scope
of the map software. If the radio is switched
on before you start the installation process,
you can still adjust the volume. You can also
use COMAND to operate the automatic air-
conditioning system and to cancel the proc-
ess. Other functions are not operational. If
possible, carry out the installation process
when the vehicle is stationary. The DVD read
speed is higher when the vehicle is stationary
than when it is in motion, so less time is
required. If the starter battery is not suffi-
ciently charged, COMAND may end the proc-
ess automatically, in order to protect the bat-
tery. Therefore, let the engine idle during the
installation process. 132

Notes on handling DVDs R
Only hold DVDs by the edge.
R Handle DVDs carefully to prevent reading
errors.
R Avoid getting scratches, fingerprints and
dust on DVDs.
R Use a commercially-available cleaning
cloth to clean discs. Do not wipe them with
a circular motion, but only in straight lines
from the centre outwards.
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
Insert the map software DVD into the single
DVD drive (Y page 77) or the DVD
changer* (Y page 78).
COMAND checks the DVD and shows a
corresponding message in the display.
