Stop-start system
The stop-start system helps to save
fuel and to reduce the 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 battery sensor ensures
that an Autostop is only performed if
the battery is sufficiently charged for
a restart.
Activation

soon as the engine is started, the
vehicle starts-off and the conditions

Deactivation
