ECO start/stop function
General notes
The ECO start/stop function switches the
engine off automatically if the vehicle stops
moving.
The engine starts automatically when you pull
away again. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle.
The ECO start/stop function is activated each
time the engine is switched on. The system is
operational when ECO symbol ¤ is shown
in the multifunction display.
If the ECO start/stop function is deactivated
( page 143), ECO symbol ¤ is not
Y
shown.
G WARNING
If the ECO symbol appears in the multifunc-
tion display when the engine is switched off,
the engine was switched off automatically.
However, all vehicle systems remain active. If
you open the door, unfasten your seat belt or
remove your foot from the brake pedal, the
engine will automatically start. The vehicle
may begin moving. There is a risk of accident.
To prevent the vehicle from accidentally pull-
ing away, do not release the brake pedal until
you want to drive on.
Do not leave the vehicle until you have
switched off the ignition and secured the vehi-
cle to prevent it from rolling away.
! Always switch the ignition off and take the
key with you when leaving the vehicle.
