WARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/
maintenance work as well as any required
repairs carried out at a qualified specialist
workshop. G
WARNING
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other
networked components. In particular,
systems relevant to safety could also be
affected. As a result, these may no longer
function as intended and/or jeopardize the
operating safety of the vehicle. There is an
increased risk of an accident and injury.
Never tamper with the wiring as well as
electronic components or their software. You
should have all work to electrical and
electronic equipment carried out at a qualified
specialist workshop.
Tampering with the electronic components,
their software or wiring can render the
operating permit invalid. Declarations of conformity

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: (Y page 27).Overview of climate control systems
Important safety notes
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 blocked filter replaced at a Mercedes-
Benz Center as soon as possible.
Observe the settings recommended on the
following pages. The windows could
otherwise fog up. This could prevent you from
observing the traffic conditions, thereby
causing an accident.
Dual-zone automatic climate control
regulates the temperature and the humidity
in the vehicle interior and filters undesirable
substances from the air.
Automatic climate control is only operational
when the engine is running. Optimum
operation is only achieved if you drive with the
side windows and sliding sunroof closed.
The climatic comfort deteriorates whilst the
sliding sunroof is open. The automatic climate
control cannot maintain the set temperature
with the sliding sunroof open. You have to
adjust the climate control manually. i
The residual heat function can only be
activated or deactivated with the ignition
switched off.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (Y page 71).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
i The integrated filter can filter out most
particles of dust, and completely filters out
pollen. A clogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance
Booklet. 92

WARNING
The driver's concentration must always be
directed primarily at road traffic.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions permit
it to be done safely.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 feet (approximately 14 m) per
second. G
WARNING
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving conditions,
such as
R speed
R outside temperature

R malfunction/warning messages
R failure of any systems
Driving characteristics may be impaired. If you must continue to drive, do so with added
caution. Contact an authorized Mercedes-
Benz Center as soon as possible.
G
WARNING
Malfunction and warning messages are only
displayed for certain systems and are
intentionally not very detailed. The
malfunction and warning messages are
simply a reminder with respect to the
operation of certain systems. They do not
replace the owner's and/or driver's
responsibility to maintain the vehicle's
operating safety. Have all required
maintenance services and safety checks
performed on the vehicle. Bring the vehicle to
an authorized Mercedes-Benz Center to
address the malfunction and warning
messages. G
WARNING
All categories of messages contain important
information which should be taken note of
and, where a malfunction is indicated,
addressed as soon as possible at an
authorized Mercedes-Benz Center.
Failure to repair the condition noted may
cause damage not covered by the Mercedes-
Benz Limited Warranty, or result in property
damage or personal injury.

WARNING
Making alterations to electronic components
can cause malfunctions.
Radio, satellite radio, amplifier, DVD changer,
navigation module, phone and voice control
are networked. If one component is not
functional or if it has been incorrectly
removed/replaced, this could impair the
operation of other components.
This could seriously jeopardize the
operational safety of your vehicle.
We recommend that you always have
maintenance work on electronic components
carried out at an authorized Mercedes-Benz
Center. G
WARNING
In order to avoid distraction which could lead
to an accident, the driver should only enter
system settings with the vehicle at a standstill
and operate the system only when road,
weather and traffic conditions permit.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 feet (approximately 14 m) per
second.
COMAND delivers information to simplify
your choice of route and guide you
comfortably and safely to your destination.
For safety reasons, we recommend that you
bring your vehicle to a standstill, paying
attention to road and traffic conditions,
before making or accepting a telephone call
or viewing navigation maps, instructions or
downloaded information on the COMAND
screen. G
WARNING
While the navigation system provides
directional assistance, the driver must remain
focused 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
observance always remains in the driver's
personal responsibility. DVD maps do not
cover all areas nor all routes within an area. G
WARNING
This equipment complies with FCC radiation
exposure limits set forth for uncontrolled
equipment and meets the FCC radio
frequency (RF) Exposure Guidelines in
Supplement C to OET65.
This equipment has very low levels of RF
energy that is deemed to comply without
maximum permissive exposure evaluation
(MPE). But it is desirable that it should be
installed and operated with at least 8inches 170
Important safety notesCOMAND

Do not tamper with or repair cargo tie-down
point, cargo tie down rings or tie downs. Have
