2008 MERCEDES-BENZ CL-Class navigation system

236 Control systemsCOMAND navigation system (route guidance)Partially digitized areas If the destination is within a partially
digitized area
COMAND guides you through fully digitized
areas for as long as possible. Route guid-
ance is conducted in the usual manner, i.e.
with navigation announcements and route
guidance displays.
Before the vehicle reaches a partially digi-
tized area, COMAND notifies you of this
with the following announcements:


“Be prepared to enter an area where
turn by turn guidance cannot be provid-
ed.”


“In 700 feet you will enter an area
where turn by turn guidance cannot be
provided.”


“You are about to enter an area where
turn by turn guidance cannot be provid-
ed.”Route guidance within a partially digi-
tized area
If you start route guidance in this type of
area, you will hear the following announce-
ment: “You are currently in an area where
turn by turn guidance cannot be provided.”
Route guidance is provided by means of a
direction arrow showing the compass
heading to the destination. COMAND will
not generate automatic navigation an-
nouncements.
If you try to call up an announcement man-
ually, (
page 239) you will hear the an-
nouncement “You are currently in an area
where turn by turn guidance cannot be pro-
vided.”.
i
The digital map may contain areas that are
only partially digitized although they are within a
digitized region.Warning!
G
Due to incomplete digitization, the route
shown on the map may differ from the actual
road/traffic situation.
If you follow the route shown on the map, for
example, it is possible that you could drive
the wrong way down a one-way street or
that a street cannot be driven on.
When using route guidance in a partially dig-
itized area, you must therefore be sure to
observe all relevant traffic regulations and
the course of the road.
All relevant traffic regulations and the
course of the road always take priority over
the route shown on the map.
i
The indicated distance can be seen here by
way of example. In reality, it may be different.
i
When you call up the route info to this type
of destination, (
page 241) the following data
shown there may differ from the actual situation:


Distance to the destination


Estimated driving time to the destination


Estimated arrival time

237 Control systems
COMAND navigation system (route guidance)
During route guidance, the display is divid-
ed. On the right-hand side you will see the
direction arrow showing the compass
heading to the destination.
On the left-hand side of the display you will
see the map with the suggested route. The
suggested route is highlighted blue. How-
ever, it may not be possible to follow the
suggested route because, for example, the
road is closed or not open for car traffic.
If, during route guidance, COMAND leads
you back into a fully digitalized area, route
guidance will simply continue in the usual
manner.
Off-road and off-map
Route guidance to an off-road
destination
COMAND can guide you to destinations
within the area covered by the digital map,
even if a destination is not located at a
road known to the system.These destinations are shown as off-road
destinations, which you can enter using
the map, for example.
In these cases, COMAND guides you for as
long as possible with navigation announce-
ments and displays on roads known to the
system.
Shortly before you reach the last known
the point to leave the digitized road net-
work, you will hear the announcement “The
destination is nearby. Follow the arrow on
the display”.
You will then see an arrow that indicates
the direction to the off-road destination.
When the off-road destination is close to
the road, “Area of dest. reached” appears
in addition below the arrow.
The section of the route from the last
known point on the map to the off-road
destination is indicated with a dashed line
after a certain length. It simply shows the
direction to the off-road destination with-
out taking account of any type of obstacles
in the way.Warning!
G
The COMAND navigation system may direct
you to off-road routes that your vehicle may
not be capable of traversing through without
damaging your tires, wheels or vehicle. It is
the driver’s sole responsibility to determine
the suitability of the route. Off-road routes
may be of varying conditions and their ap-
propriateness for use may be affected by
various factors such as time of day, time of
year and immediate weather conditions that
cannot be judged or taken into consider-
ation by the COMAND system.

see the “Direction to destination” display.Route guidance from an off-road loca-
tion to a destination

rent position of the car, vehicle is off road.

At the start of the route guidance, you will
see the “Off Road” message and a direc-
tion arrow. The direction arrow shows the
compass heading to the actual destina-
tion.
The route is highlighted blue from the near-
est road known to the system.
As soon as the vehicle is back on a road
known to the system, route guidance con-
tinues in the usual way.
Route guidance from an off-map loca-
tion to a destination
If the vehicle position is outside the area
covered by the digital map, then the vehi-
cle is in an off-map location.

see the “Off Map” message and a direction
arrow. The direction arrow shows the com-
pass heading to the actual destination.
The route is highlighted blue from the near-
est road known to the system.
As soon as the vehicle is back on a road
known to the system, route guidance con-
tinues in the usual way.
Off-road during route guidance
The road layout may differ from the data on
the digital map, due to road construction
measures, for example.
In such cases, the system cannot allocate
the vehicle’s position to the digital map
and the vehicle is therefore in an off-road
position.
The “Off Road” message and an arrow
showing the compass heading to the desti-
nation appear on the display.
As soon as the system can allocate the ve-
hicle position’s to the map again, route
guidance continues in the usual way.

Warning!
G
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.i
If Russian or Chinese is set as the system
language, the navigation announcements are in
English. You will find how to set the system lan-
guage on (
page 258).
Navigation announcements are muted during
telephone calls. You can, however, call up a cur-
rent announcement at any time. You can also
call up a current announcement at any time if
you have missed an announcement.
i
You will find the button programming on
(
page 259).
i
The announcements remain switched off
even if you start a new route guidance or if
COMAND is switched off/on with theo but-
ton.
If you switch COMAND off by removing the
SmartKey from the starter switch and then
switch the ignition back on after more than
3 minutes, the announcements are automatical-
ly switched back on.

COMAND uses the time set in COMAND as
the basis for calculating the estimated arrival
time. The clock must be set correctly in
COMAND (
page 255). The calculation of the
estimated arrival time does not additionally take
into account whether Daylight Saving Time or
standard time is applicable at the destination. If
the destination is in a different time zone, arrival
time display 8
is in local time. This is indicated
by “LT” in the display.
The following data cannot be seen until the route
calculation has been completed:
