124 Telephone*Emergency call

Emergency callYou can make an emergency call to an
emergency rescue station with a mobile
communication network.
The emergency call will be placed as long
as the corresponding mobile communicati-
on network is available. To do this, switch
the telephone on if you have not already
done so.
Emergency calls may not be possible with
all mobile phone networks or if certain net-
work services and/or telephone functions
are active. Check with your local network
operating company.
iThe emergency call will also be placed if
the phone is locked.iThis function places a call to the local
9-1-1 provider. It does not initiate a Tele
Aid call.
Warning
G
The 9-1-1 emergency call system is a public
service. Using it without due cause is a cri-
minal offense.!If you enter “1” and press the right-
hand rotary/push-button v, the num-
ber stored in memory location “1” (de-
fault is 9-1-1) will be dialed.
Pressing or holding “1” longer than 2
seconds will also initiate the call.
!It will not be possible to complete the
emergency call if the cellular system is
busy. The message “System busy,
redial?” appears.
Take appropriate measures to alert an
emergency service as soon as possible.

Important notesWarning
G
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 50 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.

Warning
G
The CD reader contains a Class 1 laser pro-
duct. There is a danger of invisible laser ra-
diation if the cover is opened or damaged.
Do not remove the cover. The CD reader
does not contain any parts which can be ser-
viced by the user. For safety reasons, have
any service work which may be necessary
performed only by qualified personnel.
!COMAND calculates the route with the
help of data that is stored on the navi-
gation CD.
Only use Mercedes-Benz navigation
CDs. Using other navigation CDs might
lead to malfunctions.
Because of changes in local traffic pat-
terns (e.g. road works) and/or incom-
plete data, errors in calculation may
occur.
As a result, the recommended route
may deviate from the ideal route. The
data stored on the CD only reflects lo-
cal conditions at the time of CD pro-
duction.
iThe CD drive can read navigation CDs
and playback audio CDs.
If an audio CD is in the CD drive and
b is pressed, the message “No CD
available. Insert NAVI-CD type DX only”
will be displayed.
Remove the audio CD and insert a
navigation CD (
page 137).

170 NavigationRoute guidanceOnce the route has been calculated, the
symbol display will appear.
If you now are at the maneuver point, you
will also hear a voice output, e.g. “Please
turn right”.During route guidance, you can select the
following 3 screen displays:

(page 175)
Voice output
During the trip, apart from visual informati-
on (symbol or map displays), COMAND
also provides all of the necessary route in-
formation via voice output.
COMAND gives you spoken recommenda-
tions

when route guidance begins

after the route has been calculated

before and during a change in the dri-
ving direction

point

Warning
G
Voice output is intended to direct you while
driving without diverting your attention from
the road and driving. Please always use this
feature instead of consulting the symbol or
map display for directions while driving
which may cause you to divert your attenti-
on from driving and increase your risk of ac-
cident.
