2012 MERCEDES-BENZ S-Class warning light

Route guidance
General notesGWARNING
COMAND calculates the route to the
destination without taking into account the
following, for example:
R Traffic lights
R Stop and right-of-way signs
R Lane merging
R Parking or stopping prohibited areas
R Other road and traffic rules and regulations
R 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
regulations during your journey. Road and
traffic rules and regulations always have
priority over the navigation commands
generated by the system.
Route guidance begins once a route has been
calculated ( Y page 156).
COMAND guides you to your destination by
means of navigation commands in the form
of audible navigation announcements and
route guidance displays.
The route guidance displays can only be seen
if the display is switched to navigation mode.
If you do not follow the navigation
announcements or if you leave the calculated
route, COMAND automatically calculates a
new route to the destination.
If the digital map contains the corresponding
information, the following applies:
R when selecting a route, COMAND tries to
avoid roads that only have limited access,
e.g. roads closed to through traffic and non-
residents.
R roads that have time restrictions (e.g.
closed on Sundays and public holidays) are
avoided for route guidance.
Change of direction
Introduction
Changes of direction have three phases:
R preparation phase
R announcement phase
R change-of-direction phase
Preparation phase
COMAND prepares you for the upcoming
change of direction. Based on the example
display below, the change of direction is
announced with a message. You see the full-
screen map.
Example display: preparation phase
:Next road;Route=Current vehicle position (the tip of the
triangle indicates the vehicle’s direction
of travel)?Current road
The display in ? depends on the setting
selected under "Text information on the map"
( Y page 185).
Announcement phase
COMAND announces the imminent change of
direction. With reference to the following
example display, the announcement is given

You can install new map software yourself
which, depending on the scope, may consist
of one or more DVDs.
The installation process can take between
10 and 120 minutes, depending on the scope
of the map software. If the radio is switched
on before you start the installation process,
you can still adjust the volume. You can also
use COMAND to operate automatic climate
control and to cancel the process. Other
functions are not operational. If possible,
carry out the installation when the vehicle is
stationary. The DVD read speed is higher
when the vehicle is stationary than when it is
in motion, so less time is required. If the
starter battery is not sufficiently charged,
COMAND may end the process automatically
in order to protect the battery. Therefore, let
the engine idle during the installation
process.GWARNING
Never leave the engine running in enclosed
spaces. The exhaust gases contain toxic
carbon monoxide. Breathing in exhaust fumes
is a health hazard and can lead to
unconsciousness or death.

Notes on handling DVDs
R Only hold DVDs by the edge.
R Handle DVDs carefully to prevent reading
errors.
R Avoid getting scratches, fingerprints and
dust on DVDs.
R Use a commercially-available cleaning
cloth to clean discs. When cleaning CDs,
you should wipe in straight lines from the
center outwards rather than in a circular
motion.
R Place DVDs back in their cases after use.
R Protect DVDs from heat and direct sunlight.
Map software copy protection
Map software for COMAND is subject to a
charge. The map software has just one
activation code which is usable in one vehicle
only, and is not transferable. You can obtain
the six-digit activation code from your
authorized Mercedes-Benz Center. If you
have lost the activation code, or if COMAND
does not accept the activation code that you
have received, contact your authorized
Mercedes-Benz Center.
Your vehicle is supplied with map software at
the factory. Depending on the country, map
software for your region is either pre-installed
(Europe/USA) or the map software is
supplied as a DVD (all other countries). You
do not require an activation code for the map
software that is provided with your vehicle.
If the map software on your vehicle has been
installed at the factory and you wish to
reinstall it, this also does not necessitate
entry of the activation code.
Installation processXLoad the map software DVD in the DVD
drive ( Y page 220).
COMAND checks the DVD and shows a
corresponding message in the display.
Map software is not compatible with the
navigation system
You will see a message that the map software
cannot be installed.

Important safety notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched on even during the daytime. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations.
Information about driving abroad
Converting to symmetrical low beam
when driving abroad: switch the headlamps
to symmetrical low beam in countries in
which traffic drives on the opposite side of the
road to the country where the vehicle is
registered. This prevents glare to oncoming
traffic. Symmetrical lights do not illuminate
as large an area of the edge of the road.
Have the headlamps converted at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center, as close to the border
as possible before driving in these countries.
Converting to asymmetrical low beam
after returning: have the headlamps
converted back to asymmetrical low beam at
a qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center, as soon as
possible after crossing the border again.

prevailing light, sight and traffic conditions.
The system may be impaired or unavailable
when
R visibility is poor, e.g. due to snow, rain, fog,
or heavy spray
R the optical sensor area of the windshield is
dirty, fogged up, or covered by a sticker for
example
The system cannot recognize the following
road users:
R Road users without a lighting system of
their own, e.g. pedestrians
R Road users with dim lighting of their own,
e.g. cyclists
R Road users whose lighting is obstructed,
e.g. road users behind a guardrail
R In some seldom cases, even road users with
a lighting system of their own may be
recognized too late or not at all.
The automatic high-beam headlamps will then
not be deactivated or it will be activated in
spite of preceding or oncoming road users.
This could endanger you and/or others and
cause an accident. Always pay close attention
to the traffic situation and switch off the high
beam manually if necessary.
Headlamps fogged up on the inside
The headlamps may fog up on the inside if
there is high atmospheric humidity.
XDrive with the headlamps switched on.
The level of moisture diminishes,
depending on the length of the journey and
the weather conditions (humidity and
temperature).
If the level of moisture does not diminish:
