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
automatically if the vehicle stops moving.
The engine starts automatically when the
driver wants to pull away again. The ECO
start/stop function thereby helps you to
reduce the fuel consumption and emissions
of your vehicle.
Every time you switch on the engine using the
SmartKey or the Start/Stop button, the ECO
start/stop function is activated.
If the ECO start/stop function has been
manually deactivated (
Y
page 160) or a
malfunction has caused the system to be
deactivated, the ¤ symbol is not
displayed.
AMG vehicles: the
Stop/Start active or
Stop/Start inactive message in the AMG
menu in the multifunction display goes out.
AMG vehicles: the ECO start/stop function
is only available in drive program C.
i AMG vehicles: if automatic cylinder shut-
off is active in drive program C, the number
of active cylinders 4 is also shown in the
¤ symbol. This means that the engine
is operating with four cylinders.
If cylinder shut-off is not active, the engine
will operate with all eight cylinders. In this
case, the number of active cylinders 8 is
shown in the ¤ symbol.
