instruction manual, may cause harmful
interference to radio communications.GWarning
This equipment complies with FCC radiation
exposure limits set forth for uncontrolled
equipment and meets the FCC radio
frequency (RF) Exposure Guidelines in
Supplement C to OET65.
This equipment has very low levels of RF
energy that is deemed to comply without
maximum permissive exposure evaluation
(MPE). But it is desirable that it should be
installed and operated with at least 8 inches
(20 cm) and more between the radiator and a
person's body (excluding extremities: hands,
wrists, feet and legs.)
Correct use
Observe the following information when using
COMAND:
R the safety notes in this manual
R all road traffic regulations
i Improper work on electronic components
or other systems (such as radio, DVD
changer) and their software may result in
malfunction or failure. Even systems that
have not been modified could be affected
because the electronic systems are
connected. Electronic malfunctions can
seriously jeopardize the operational safety
of your vehicle.
i Only have work or changes to electronic
components carried out at a qualified
specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. Daimler
recommends that you use an authorized
Mercedes-Benz Center for this purpose. In
particular, work relevant to safety or on
safety-related systems must be carried out
at a qualified specialist workshop.
i Protection against theft: this device is
equipped with technical provisions to
protect it against theft. Further information
on protection against theft can be obtained
from an authorized Mercedes-Benz Center.
Vehicle equipment
These operating instructions describe all
standard and optional equipment available
for your vehicle at the time of going to print.
Country-specific deviations are possible.
Please note that your vehicle may not be
equipped with all features described. This
includes safety-related systems and
functions. The equipment in your vehicle may
therefore differ from some of the descriptions
or illustrations. The original purchase
agreement lists all systems installed in your
vehicle. Contact an authorized Mercedes-
Benz Center if you have any questions about
equipment or operation.
Function restrictions
For safety reasons, some COMAND functions
are restricted or unavailable while the vehicle
is in motion. You will notice this, for example,
because you will either not be able to select
certain menu items or because COMAND will
display a message to this effect.
To protect the integrated hard drive against
damage, COMAND deactivates the drive at
very high temperatures. The following
functions will be temporarily unavailable:
R navigation system
R Voice Control System
R address book
R MUSIC REGISTER

vehicle's speed, braking in good time, and
steering correctly. Always adapt your driving
style to suit the prevailing road and weather
conditions. Always pay attention to traffic
conditions and your surroundings. Otherwise,
you may fail to recognize dangers in time,
cause an accident and injure yourself and
others.
i USA only:
This device has been approved by the FCC
as a “Vehicular Radar System”. The radar
sensor is intended for use in an automotive
radar system only. Removing, tampering
with, or altering the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be activated ( Y page 342) and operational.
Monitoring range
Active Blind Spot Assist monitors the area up
to 10 ft (3 m) behind your vehicle and directly
next to your vehicle as shown in the diagram.
For this purpose, Active Blind Spot Assist
uses sensors in the rear bumper.GWarning
Active Blind Spot Assist monitors certain
areas in the immediate vicinity of your vehicle.
Vehicles that approach and drive past at high
speeds are not detected. No visual nor
audible warnings are emitted and the system
does not brake the vehicle to correct your
course.
If the lanes are very wide, it may not be
possible to monitor the complete width of the
neighboring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in a staggered formation.
This may be the case if vehicles are driving at
the edge of their lane that is furthest away
from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others.
If the lanes are narrow, the system may be
unable to distinguish the neighboring lane
from the one beyond it. For this reason,
vehicles in the farther lane may be indicated,
especially if the vehicles are driving in a
staggered formation in different lanes. In
particular, this may be the case if the vehicles
are driving at the edge of their lane nearest
your vehicle. Due to the nature of the system,
warnings may be issued in error when driving
close to crash barriers or similar solid lane
borders.
Two Active Blind Spot Assist sensors are
integrated into the front and rear bumpers
respectively. An additional sensor is located
behind the cover in the radiator grill. Make
sure that the bumpers are free from dirt, ice,
or slush around the sensors. The rear radar
sensors must not be covered, for example by
cycle racks or overhanging loads. Following a
severe impact or in the event of damage to
the bumpers, have the function of the radar
sensors checked at a qualified specialist
workshop, e.g. an authorized Mercedes-Benz
Center. Active Blind Spot Assist may
otherwise fail to work correctly.

Driving when your engine is overheated can cause some fluids which may have leaked into the
engine compartment to catch fire. You could be seriously burned.
Steam from an overheated engine can cause serious burns which can occur just by opening the
engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until the engine has cooled down.
! If the coolant temperature exceeds 248 ‡(120 †) do not continue driving. The engine will
otherwise be damaged.
