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.

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.
During route guidance, you will not receive
any information on
Traffic lights
Stop and yield signs
Parking or stopping zones
One-way streets
Narrow bridges
Similar traffic regulation data
You should therefore always strictly observe
traffic regulations while driving. Drive care-
fully and always obey traffic laws and road
signs even if they contradict COMAND in-
structions.
