Safety instructions
WarningG
In order to avoid distraction which could
lead to an accident, the driver should insert
CDs with the vehicle at a standstill and
operate the audio system only if 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.
WarningG
The CD drive is a Class 1 laser products.
There is a danger of invisible laser radiation
when you open or damage the cover.
Do not remove the cover. The CD drive does
not contain any parts which can be serviced
by the user. For safety reasons, have any ne-
cessary service work performed by qualified
personnel.
Tips on data storage media
!
Do not attach labels of any type to the
CD. They may become detached and
damage the drive.
!
Your CD drive has been designed to
play CDs which correspond to the IEC
60908 standard. Therefore only CDs
not exceeeding a thickness of 1.3 mm
can be used.
If you insert thicker data carriers, e.g.
ones that have data on both sides (one
side with DVD data, the other side with
audio data), they will become stuck and
damage the drive.
Do not play single CDs (80mm) with an
adapter. An adapter could become
stuck and damage the drive. Only use
12 cm diameter CDs.

WarningG
The driver should not operate any of the

control panel while driving the vehicle under
any circumstances. These features can
distract the driver from traffic conditions
and should only be operated by the rear seat
occupants.
Similarly, the driver should not wear a Rear
Audio headset while operating the vehicle
under any circumstances. The use of a
headset while driving the vehicle could
drastically impair the ability to react to
audible traffic conditions (e.g. emergency
sirens from police/fire/ambulance, another
drivers horn, etc).
WarningG
When not in use, headsets should be stored
in a safe location (e.g. one of the vehicle’s
storage compartments) so that they are not
loose within the passenger compartment
during braking, vehicle maneuvers or a
traffic accident. Objects moving within the
passenger compartment could cause
serious personal injury to vehicle
occupants.
WarningG
Due to a potential choking hazard, wired
headset usage by children should only occur
with adult supervision.

WarningG
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle. Whether or not prohibited by law, for
safety reasons, the driver should not use the
cellular telephone while the vehicle is in mo-
tion. Stop the vehicle in a safe location be-

traffic conditions permit.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e.
without being connected to an external an-
tenna) from inside the vehicle while the en-
gine is running. Doing so could lead to
malfunction of the vehicle’s electronic sys-
tems, possibly resulting in an accident and
personal injury.

Important notes
Important notes
WarningG
For safety reasons, you should only enter a
destination when the vehicle is stationary.
When the vehicle is in motion, a passenger
should enter the destination. Study manual
and select route before driving.
Do not watch display screen or operate but-
tons while the vehicle is in motion - let voice
instructions guide you. Stop at a safe locati-
on before using buttons or making correc-
tions.
Traffic regulations always have priority over
any route recommendations given.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your car is co-
vering a distance of 44 feet (approximately
14 m) every second.
The route calculated by COMAND is a re-
commendation on how to best reach your
selected destination.

any information on
Traffic lights
Stop and yield signs
Parking or stopping zones
One-way streets
Narrow bridges

traffic regulations while driving. Drive care-
fully and always obey traffic laws and road
signs even if they contradict COMAND in-
structions.
