When reinstalling a map software that has
been installed in that vehicle already, an
activation code is not required.
Installation process
i
The installation process can take
between 10 and 120 minutes, depending
on the
size of the map software. If the radio
is switched on when you start the
installation process, you can still adjust the
volume. During the installation process,
some COMAND functions are suspended.
Still available are the COMAND functions
for automatic air conditioning operation
and canceling the installation process.
If possible, carry out the installation when
the vehicle is stationary. When the vehicle
is stationary, the reading rate of the DVD
drive is higher than in a moving vehicle and
the installation process requires less time. G
Observe Safety notes, see page 68.
i COMAND may switch off during the
installation process automatically in order
to protect the battery. This may happen
when the engine is switched off and the
vehicle battery has insufficient power. If
this occurs,

restart the installation with the
engine running. Similarly, if the SmartKey
position is unintentionally switched to 0,
restart the installation. G
Warning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and lead to death. Do not
run the engine in confined areas (such as a
garage) which are not properly ventilated. Installing

the temperature set by the operator. In addition, the air conditioning dehumidifies
the interior air and helps prevent window
fogging.
i
Condensation may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction. G
Warning!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.

If the air conditioning cannot be activated
again, this indicates that the air
conditioning is losing refrigerant. The
compressor has turned off.
Have the air conditioning checked at the
nearest authorized Mercedes-Benz Center.
Selecting Mono mode Mono is used to adjust the climate zones for
the entire vehicle at the same time. When the
Mono function is switched on and you change

changes will be carried out in the same
manner for all climate zones.196

Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.
G
Warning!
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled
replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center. G
Warning!
Follow the recommended settings for heating
and cooling

given on the following pages and
in the “COMAND automatic climate control”
section. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
X Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing objects on
the air flow-through exhaust slots below the
rear window.
i If the vehicle interior is hot, ventilate the
interior before driving off, see “Summer
opening feature”

(Y page 283). The climate
control will then adjust the interior
temperature to the set value much faster.

G
Warning!
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature). This
may cause burns or frostbite to unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribution
adjustment to direct the air to air vents in the
vehicle interior that are not in the immediate
area of unprotected skin.
For best possible performance of the climate
control:
X Keep the air intake grille in front of the
windshield free of snow, leaves, sticks, and
any other debris.
