traffic jam.
On vehicles with manual
transmission, the engine is started automatically as soon as the clutch is
depressed.
On vehicles with manual transmission
automated, the engine is started
automatically as soon as the brake
pedal is released.
A vehicle battery sensor ensures that
an Autostop is only performed if the
vehicle battery is sufficiently charged
