® Brake does not always clearly
interpret complex traffic situations. If a vi-
sual and/or acoustic warning is issued in
an uncritical driving situation, or if the ve-
hicle brakes lightly, you can interrupt the
PRE-SAFE® Brake maneuver by
pressing down all the way on the accel-
erator or using kickdown
releasing the brake pedalThe PRE-SAFE
® Brake maneuver is termi-
nated immediately when
you avoid the obstacle by evasive
steering
you drive less than 9 mph (15 km/h)
an obstacle can no longer be identified
ahead of you
the system no longer senses the risk of
a collisionAfter a hard collision or damage to the
front of the vehicle from an accident, have
the settings and operation of the radar
sensors checked by an authorized
Mercedes-Benz Center.

86 Control systemsCOMAND operating safetyWarning!
G
Any alteration of electronic components or
software can cause malfunctions.
Radio, satellite radio, amplifier, CD/DVD
changer, navigation module, telephone and
Voice Control Systems* are interconnected.
Therefore, if one of the components is not
operational, or has not been removed/ re-
placed properly, the function of other com-
ponents could be impaired.
Such conditions might seriously impair the
operating safety of your vehicle.
We recommend to have any service work on
electronic components carried out by an au-
thorized Mercedes-Benz Center.
Warning!
G
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) ev-
ery 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 encour-
age the driver to stop the vehicle in a safe
place before answering or placing a call, or
consulting the COMAND screen to read nav-
igational maps, instructions, or downloaded
information.
Warning!
G
While the navigation system provides direc-
tional assistance, the driver must remain fo-
cused 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 ob-
servance always remains in the driver’s per-
sonal responsibility. DVD maps do not cover
all areas nor all routes within an area.

Notes about video DVD operation
COMAND can playback commercially
available, prerecorded video DVDs that
bear the following label. You will usually
find the label on the DVD booklet, the inlay,
or the DVD itself.
Some DVDs may not comply with the
NTSC or PAL TV playback standards.
Sound, picture and other playback prob-
lems may occur when you play such DVDs. COMAND can playback video DVDs meet-
ing the following requirements:
Correct regional code
NTSC or PAL TV standard
The appropriate information is usually giv-
en either on the DVD or the DVD box. The
factory setting of COMAND is regional
code 1. The setting can be changed at an
authorized Mercedes-Benz Center. This
will allow you to playback video DVDs with
other regional codes, as long as they com-
ply with the NTSC or PAL TV standard.

ware and writers available. This variety means
that there is no guarantee that the system will be
able to play discs that you have written/copied
yourself.
