Automatic start/stop
function*
The principle
The automatic start/stop function helps you to
save fuel and reduce emissions. To do so, the
system automatically switches the engine off
while the vehicle is stationary, e.g. in a traffic
jam or at traffic lights; the ignition remains
switched on. As soon as you depress the clutch,
the engine starts automatically.
Automatic operation
After every engine start, the automatic start/
stop function is on standby. It is activated as
soon as you drive forwards at faster than
5 km/h, approx. 3 mph.
Stopping the engine
When rolling to a halt, e.g. at a traffic light, or
when the vehicle is stationary, shift to neutral
and release the clutch.
With the vehicle stationary, the engine
is switched off and the indicator light
lights up.
The air flow of the ventilation/air conditioner is
reduced.
Engine is not switched off
Before the engine is switched off, the system
checks whether certain conditions related to
safety and comfort have been met.
