Fuel system messages 3 95.
Overrun cut-off The fuel supply is automatically cut-
off during overrun, i.e. when the
vehicle is driven with a gear engaged
but accelerator is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.
Stop-start system
The stop-start system helps to save
fuel and to reduce exhaust emissions. When conditions allow, it switches off
the engine as soon as the vehicle is
at a low speed or at a standstill, e.g.
at a traffic light or in a traffic jam. It
starts the engine automatically as
soon as the clutch is depressed.
A vehicle battery sensor ensures that an Autostop is only performed if thevehicle battery is sufficiently charged
for a restart.
Activation
The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.
Driving and operating117● the self-cleaning function of thediesel particle filter is not active
● the vehicle has moved since the last Autostop
● the brake vacuum is sufficient ● the windscreen wipers are not operating at fast speed
● reverse gear is not selected
● heated rear window is not operating
Ambient temperature near to the
freezing point can inhibit an Autostop.
For manual transmission automated
vehicles, an Autostop may be
inhibited until a speed of approx.
6 mph is reached.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 113.
Vehicle battery discharge protection
