112 Navigation
Introduction
The digital data for the map software will
become obsolete, just like conventional
road maps. Optimum route guidance by
the navigation system is only achieved
with up-to-date map software. Information
on new map software versions is available
from an authorized Mercedes-Benz Center.
You can have the map software updated
there by means of a DVD or perform the
update process yourself.
Notes on DVD discs

Only touch the discs at the edges.

Handle the discs with care in order to
prevent reading errors.

Avoid scratching, leaving fingerprints
and dust on the discs.

Use a commercially available cleaning
cloth to clean discs. Always wipe in a
straight line from the inside outwards,
never in a circular motion.

After use, put the discs back into the
box.

Protect the discs from heat and direct
sunlight.
Introduction
Safety instructions
G Warning
For safety reasons, only enter a destination
when the vehicle is stationary. When the ve-
hicle is in motion, a passenger should enter
the destination. Study manual and select
route before driving.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
COMAND calculates the route to the desti-
nation without taking account of the follow-
ing:

Traffic lights

Stop and right-of-way signs

Lane merging

Parking or stopping prohibited areas

Other road and traffic rules and regula-
tions

Narrow bridges
G Warning
COMAND may give incorrect navigation
commands if the data in the digital map
does not correspond with the actual road/
traffic situation. Digital maps do not cover
all areas nor all routes within an area. For ex-
ample, if the traffic routing has been
changed or the direction of a one-way road
has been reversed.
For this reason, you must always observe
applicable road and traffic rules and regula-
tions during your journey. Road and traffic
rules and regulations always have priority
over the navigation commands generated by
the system.
G Warning
Navigation announcements are intended to
direct you while driving without diverting
your attention from the road and driving.
Please always use this feature instead of
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your at-
tention from driving and increase your risk
of an accident.

148 Navigation
Route guidance
COMAND guides you to the destination by
means of driving recommendations in the
form of navigation announcements or
route guidance displays.
i The route guidance displays only appear if
the display has been switched to navigation
mode.
If for some reason you do not follow the
driving recommendations or leave the cal-
culated route, COMAND automatically cal-
culates a new route to the destination.
If the map data contains corresponding in-
formation during route guidance
COMAND tries to avoid roads with limited
passability, e. g. roads that are blocked for
through-traffic and are for residents only.
Time restrictions of roads (e.g. blocked on
Sundays and public holidays) are only tak-
en into account for route guidance if the
digital map contains corresponding infor-
mation during the blocked time periods.Driving maneuvers are given in three phas-
es:

Preparation phase

Announcement phase

Maneuver phase
Route guidance
General information
G Warning
COMAND calculates the route to the desti-
nation without taking account of the follow-
ing:

Traffic lights

Stop and right-of-way signs

Lane merging

Parking or stopping prohibited areas

Other road and traffic rules and regula-
tions

Narrow bridges
COMAND may give incorrect navigation
commands if the data in the digital map
does not correspond with the actual road/
traffic situation. For example, if the traffic
routing has been changed or the direction of
a one-way road has been reversed.
For this reason, you must always observe
applicable road and traffic rules and regula-
tions during your journey. Road and traffic
rules and regulations always have priority
over the navigation commands generated by
the system.

G Warning
For safety reasons, you should only select a
destination when the vehicle is stationary.
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’ per-
sonal responsibility. DVD maps do not cover
all areas nor all routes within an area.
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 vehicle is
covering a distance of 44 feet (approximate-
ly 13.5 m) every second.
G Warning
During route guidance, you will not receive
information on:

traffic lights

stop and yield signs

parking or stopping zones

one-way streets

narrow bridges, or

other 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 navigation sys-
tem instructions.
G Warning
Navigation announcements are intended to
direct you while driving without diverting
your attention from the road and driving.
Please always use this feature instead of
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your at-
tention from driving and increase your risk
of an accident.
G Warning
Please do not use the Voice Control System
in an emergency, as the tone of your voice
may change in a stressful situation. This
could cause a delay in completing your
phone call in a timely manner. This could
distract you in an emergency situation and
cause you to be involved in an accident.
