during overrun, i.e. when the vehicle

is driven with a gear engaged but

accelerator pedal 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 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. The ignition stays on.
The engine switches on automatically

when certain conditions apply or

restart is activated by a driver.
