Operating safety
General notes G
WARNING
Vehicles with HYBRID: ensure that you read
the 
 "HYBRID" supplement. You may otherwise
fail to recognize dangers. G
WARNING
Making alterations to electronic components
can cause malfunctions.
Radio, 
satellite radio, amplifier, DVD changer,
navigation module, phone and voice control
are networked together. If one component is
not functional or if it has been incorrectly
removed/replaced, this could impair the
operation of other components.
This could seriously jeopardize the
operational safety of your vehicle.
We recommend that you always have
maintenance work on electronic components
carried out at an authorized Mercedes-Benz
Center. G
WARNING
In order to avoid distraction which could lead
to 
 an accident, the driver should enter system
settings while the vehicle is at a standstill, and operate the system only when permitted by
road, weather and traffic conditions.
Bear in mind that at a speed of just 30 mph
(approximately 
50 km/h), your car covers a
distance of 44  feet (approximately 14  m) every
second.
COMAND supplies you with information to
help you select your route more easily and
guide you conveniently and safely to your
destination. For safety reasons, we
encourage the driver to stop the vehicle in a
safe place before answering or placing a call,
or consulting the COMAND screen to read
navigational maps, instructions, or
downloaded information. G
WARNING
While the navigation system provides
directional 
 assistance, the driver must remain
focused on safe driving behavior, especially
attention to traffic and street signs, and
should utilize the system's audio cues while
driving.
The navigation system does not supply any
information on stop signs, yield signs, traffic
regulations or traffic safety rules. Their
observance always remains in the driver's
personal responsibility. DVD maps do not
cover all areas nor all routes within an area.

RSS-210 of Industry Canada. Operation is
subject to the following two conditions:
1. This device may not cause interference,
and
2. this device must accept any interference
received, including interference that may
cause undesired operation of the device.
Any unauthorized modification to this
device could void the user's authority to

IntroductionCOMAND 

For example, the "Navi" function can be used
from the driver's side while the "Video"
function 
is used on the front-passenger side.
Use the remote control to operate COMAND
from the front-passenger side with
SPLITVIEW.
Please bear the following in mind
R Your vehicle may be equipped with
SPLITVIEW, depending on its date of
production. The use of SPLITVIEW is
currently not permitted in the following
states: AL, AZ, CO, IL, LA, MA, MD, NH, PA,
VA, VT, WA, WI, and WV or in the Canadian
provinces of Manitoba, Newfoundland,
New Brunswick, and Prince Edward Island.
It is the driver's responsibility to observe
ALL regional legally prescribed regulations.
If your vehicle is registered in a state or
province in which SPLITVIEW is not
approved, this function must be
deactivated. Please contact an authorized
specialist dealer to check whether
SPLITVIEW is approved in your state or
province.
R Volume adjustment for the cordless
headphones can be carried out on the
headphones. Before putting on the
headphones, make sure that the volume
has not been set too high.
R The remote control can be used for the
volume adjustment of corded headphones.
R You can only use media from the driver's
and front-passenger sides separately if the
media are from different sources. Example:
on the driver's side, an audio CD is being
played by the DVD changer. This means
that on the front-passenger side, the DVD
changer cannot be used to play a different
disc type, for instance a video DVD.
However, other media can be used at the
same time on the front-passenger side,
including radio, memory card, MUSIC
REGISTER, Media Interface, USB or AUX.
R If you use the same medium on both sides,
settings for this medium can be carried out
from either side. R
There must be intervisibility between the
headphones and the display so that
COMAND 
can optimally transmit music and
speech via the infrared signal on the front-
passenger's headphones. For this reason,
please also observe that the headphones
have left and right sides, and use them
correctly.
R Only entertainment functions, i.e. audio
and video, can be used separately via
SPLITVIEW.
R The multifunction steering wheel can only
be used for functions which relate to the
driver's side.

lock. After this time or after the SmartKey has
been removed, the settings on the front-
passenger side are saved for approximately
30 minutes longer. After this period,
reactivation on the front-passenger side
means that the settings from the driver's side
will be used.
Cordless headphones for the front
passenger There are different cordless headphones for
the front passenger and the rear
compartment.
The cordless headphones for the front
passenger can be identified by SPLITVIEW

Introduction
You can use the individualization function to
fine tune the Voice Control System to your
voice and therefore improve voice
recognition. This means that other users'
voices will not be recognized as easily. For
this 
reason this function can be switched off.
Individualization comprises two parts and
takes approximately 5 minutes. It consists of
training the system to recognize a certain
number of digit sequences and voice
commands.
Starting new individualization
Individualization can only be started when the
vehicle is stationary. Before starting, switch
off all devices or functions which could
interfere, such as the radio or the navigation
system. After starting the session, the system System settings
