Automatic engine switch-off
General notes
The ECO start/stop function is operational
when the
è
ECO symbol is shown in the sta-
tus bar of the display.
For this to happen, various conditions, including
the following, must be met:
R
the ECO start/stop function is switched on.
The indicator lamp in the
è
ECO button is
lit (

R
the outside temperature is above 32 ‡ (0 †).
R
the engine has reached its operating temper-
ature.
R
the set temperature for the vehicle interior
has been reached.
R
the condition of charge of the starter battery
is sufficient.
R
the system detects that the windshield is not
fogged up when the air-conditioning system
or automatic climate control is switched on.
R
the hood is closed.
R
the driver's seat belt is fastened.
R
the driver's door is closed.
R
there is no danger of immediately rolling
backwards, e.g. when stopped on a steep gra-
dient.
If a trailer is attached and/or a rear carrier
system is installed and connected electri-
cally, this danger is detected on less steep
gradients.
Only if all the conditions for automatic engine
switch-off are fulfilled, does the display show
the
è
ECO symbol.
All of the vehicle's systems remain active when
the engine is switched off automatically.
The engine can be switched off automatically a
maximum of four times (initial stop, then three
subsequent stops) in succession. After that, the
display hides the
è
ECO symbol. Automatic
engine switch-off is not possible again until the
è
ECO symbol is shown again.
If you open the hood after an automatic engine
switch-off, automatic engine start is deactiva-
ted. Once the hood is closed, you have to start
the engine manually.
If the vehicle is stopped in D or N, the ECO start/
stop function switches off the engine automat-
ically once the vehicle is stationary.
