of your vehicle .Should you have any ques-
tions concerning equipment and operation,
please consult a Mercedes-Ben zService
Centre. Operating safety
Safety notes
G
WARNING
All work on the vehicle and, in particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop. The specialist workshop
must have the necessary specialist knowl-
edge and tools to carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. G
WARNING
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-
ger protec tyou and other persons as inten-
ded. In addition, there is a risk that you may
lose control of your vehicle and thus cause an
accident. G
WARNING
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-
tect you 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
WARNING
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. General notes
The following information applies to all radio
system components in the vehicle and to
COMAND:
The radio system components in this vehicle
are compliant with the basic requirements
and all other relevant conditions of Directive
1999/5/EC. You can obtain further informa-
tion from any Mercedes-Benz Service Centre.
The equipment is approved by the vehicle
manufacturer in accordance with European
Automotive EMC Directive 95/54/EC. Oper-
ation according to its intended purpose is
thus approved for your vehicle. The equip-
ment does not require certification.
The equipment conforms to the relevant
equipment-specific EMC specifications in
accordance with the following European
standards:
R EN 55013
R EN 55020
Therefore, adherence to the relevant specifi-
cations for electromagnetic compatibility is
guaranteed for this device.
As a result, interference caused by your
equipment to other electrical/electronic
equipment and interference to your equip-
ment caused by other electrical/electronic
equipment can be largely prevented. Introduction

measures (PRE-SAFE
®
) are activated simul-
taneously.
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 there is no longer any dange rofarear-end
collision.
R no obstacle is detected in front of your
vehicle.
BAS PLUS is then deactivated.
Vehicles with COMAND and navigation sys-
tem: the rada rsensor system is switched off
automatically in the vicinity of radio telescope
facilities (Y page 389).
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 ( Ypage 242).
For BASP LUS to assist you when driving, the
radars ensor system must be switched on and
operational; see "Rada rsensor system" in the
index. G
WARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations. BAS
PLUS cannot intervene in these cases.
There is a risk of an accident. Always pay
careful attention to the traffic situation and be
ready to brake.
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 radar sources
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
BAS PLUS does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, BAS PLUS may not intervene in
critical situations. There is a risk of an acci-
dent .Always pay careful attention to the traf-
fic situation and be ready to brake.
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.
If BA SPLUS is not available due to a malfunc-
tion in the radars ensor 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/ho rifbraking 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.Ift he
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 (Y page 121).74
Driving safety systemsSafety

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
