Applies to: vehicles with start/stop system
Before and during each stop phase, the system checks that certain conditions have been met and decides whether to switch off the engine and for how long. For instance, the engine is not switched off if the power consumption is high. Whether or not the engine is started/stopped automatically depends on factors such as the following:
- Ambient conditions (downhill/uphill gradient, altitude and temperature)
- Battery (charge level, temperature and power consumption)
- Engine temperature
- Driver assist systems
- Driving style
If the indicator lamp 
appears on the instrument cluster display, the engine will not be switched off.
