Auto Start Stop Function - Porsche 911 Manual

Auto Start Stop function

The engine stops automatically when the vehicle is
stopped, e.g. at traffic lights or in a traffic jam, if all
preconditions for stopping the engine automatically
are met. The engine can also stop automatically
when the vehicle stops while travelling at walking
pace. The Auto Start Stop function thus helps to
save fuel.
The ignition stays on even when the engine switches
off automatically. All safety functions are still
available.

Information
The engine will start automatically in certain situa-
tions, e.g. to ensure passenger comfort via air con-
ditioning. The gearshift lever must be in neutral. In
some cases, a message prompting you to press the
brake pedal will be displayed on the instrument
cluster.
Reaction after leaving the vehicle
If the driver's door is opened during an automatic
engine stop, the engine will not start automatically.
An automatic engine start can still be performed by
pressing the clutch pedal down fully.
Auto Start Stop mode is resumed if one of the fol-
lowing requirements is detected:
– The brake pedal is pressed, the driver's door is
closed and the driver's seat belt is fastened.
– or –
Auto Start Stop function
The driver's door is closed and the driver's seat
belt is then fastened.
– or –
The accelerator pedal is pressed with the driver's
door closed and the driver's seat belt fastened.
If the driver leaves the vehicle while the engine has
stopped automatically (driver's door open and pedals
released), the requirements specified above must be
detected within 30 seconds in order for the engine
to start and Auto Start Stop mode to be resumed.
Switching off the Auto Start Stop function within 30
seconds after leaving the vehicle results in an engine
start only after the driver's door has been closed and
the driver's seat belt has been fastened. If none of
these requirements are met, the engine has to be
started manually 30 seconds after leaving the ve-
hicle. A message prompting you to start the engine
manually appears on the instrument cluster.
