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.

Important safety notes

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. G
WARNING
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise, the windows could fog up,
impairing visibility and endangering you and
others.
Automatic climate control controls 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.

The "residual heat" function can only be
activated or deactivated with the ignition
switched off.
i The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 134).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature ( Y page 78).
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.
Since the replacement interval depends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet. 118

Service interval display
Service messages Information on the type of service and service
intervals (see the separate Maintenance
Booklet).
You can obtain further information from an
authorized Mercedes-Benz Center or at
http://www.mbusa.com (USA only).
The ASSYST service interval display informs
you of the next service due date.
If
a service due date has been exceeded, you
also hear a warning tone.
The multifunction display shows a service
message for several seconds, e.g.:
Service A in 99999 Miles
Service A Due Now
Service A Exceeded By 99999 Miles Maintaining the time-dependent service
schedule:
X
Before disconnecting the battery, note
down the service due date displayed.
or:
X After reconnecting the battery, subtract
the
battery disconnection periods from the
service date shown on the display.
i The
service interval display should not be
confused with the 4 engine oil level
display.
The symbol and the letter indicate which type
of service is due:
¯ Minor service A
± Major service B
The ASSYST service interval display does not
take into account any periods of time during
which the battery is disconnected.
Hiding a service message X
To hide the service message, press the
% back button on the multifunction
steering wheel ( Y page 31)(Y page 211).
Displaying service messages Use the buttons on the multifunction steering
wheel.
X
Switch on the ignition.
X Press V
or U to select the standard
display menu on the steering wheel
(Y page 212).
X Select & or * to select the service
interval display.
The ¯ or ± service symbol and the
service due date are displayed.
Points to note Arduous operating conditions or increased
loads
on the vehicle will require some service
work to be performed more often than for a
vehicle in normal use. Such arduous
conditions include regular city driving with
frequent intermediate stops and use in Maintenance
