Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 34). Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could other-
wise mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air dehumidifi-
cation function
R switch on the "demist windscreen" function
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. Optimum operation is only achieved when the side windows and the roof
are closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 149).
i Ventilate the vehicle for a brief period
during warm weather. This will speed up the cooling process, and the desired vehicle
interior temperature will be reached more
quickly. i
An hour after the key has been removed,
it is possible that the residual heat function may be activated automatically in order to
dry the air-conditioning system. The vehicleis then ventilated for 30 minutes to dry the air-conditioning system. 140

General notes
:
ECO start/stop display
If the ¤ symbol is shown in green in the
multifunction display, the ECO start/stop
function switches the engine off automati-
cally if the vehicle stops moving.
The ECO start/stop function is activated
whenever you switch on the engine using the
key or the Start/Stop button.
If the ECO start/stop function has been man- ually deactivated (Y page 160) or a malfunc-
tion has caused the system to be deactivated, the ¤ symbol is not displayed.
AMG vehicles: the ECO start/stop function
is only available in drive program C.
For further information on automatic engine
switch-off (Y page 159) and automatic
engine start (Y page 159).
Automatic engine switch-off If the vehicle is braked to a standstill in
Dor N,
the ECO start/stop function switches off the engine automatically.
The ECO start/stop function is operational
and the ¤symbol is lit green in the multi-
function display if:
R the indicator lamp in the ECO button is lit
green
R the outside temperature is within the range
that is suitable for the system
R the engine is at normal operating temper-
ature
R the set temperature for the vehicle interior
has been reached
R the battery is sufficiently charged R
the system detects that the windscreen is
not misted up when the air-conditioning
system is switched on
R the bonnet is closed
R the driver's door is closed and the driver's
seat belt is fastened

when the engine is switched off automati-
cally.
i All vehicles (except AMG vehicles):
automatic engine switch-off can take place a maximum of four times consecutively (ini-
tial stop, then three subsequent stops). The
¤ symbol is lit yellow in the multifunc-
tion display after the engine has been star- ted automatically for the fourth time. Whenthe ¤ symbol is lit green in the multi-
function display, automatic engine switch-
off is again possible.
i AMG vehicles:
the number of consecu-
tive automatic engine stops is unlimited.
i The HOLD function can be activated if the
engine has been switched off automati-
cally. It is then not necessary to continue
applying the brakes during the automatic
stop phase. When you depress the accel-
erator pedal, the engine starts automati-
cally and the braking effect of the HOLD
function is deactivated.
