restarts it again when required.
The following conditions must be met for the
system to automatically stop the engine:
Driver is detected as present
Driving speed exceeded 6 mph (10 km/h)
since previous stop
Engine at normal operating temperature
Vehicle battery fully charged
Air conditioning demand not too high

System operation
At very low speeds a status icon will be shown
on the Folding Driver Display.
The icon will illuminate amber if conditions have
not been met and the system is not available.
If all conditions have been met and the system
is available, the icon will illuminate green.
The system will automatically stop the engine
when the brake pedal is depressed and the
vehicle slows to a complete stop.
The message 'ENGINE STOPPED' will be shown
on the Folding Driver Display.
