Auto Start Stop function.
Convenient energy management: if no power is required, such as in a tailback or at a red light, the Auto Start Stop function automatically switches off the engine. As soon as the driver’s foot leaves the brake pedal, the engine starts up reliably and the full, unrestricted power of the engine is available.
Red lights, traffic jams, level crossings – in everyday driving situations there are countless instances where the engine is idling, unnecessarily burning fuel. The Auto Start Stop function prevents this. It switches off the engine when the vehicle is stationary and the driver operates the brake. Of course this only happens when energy is not needed anywhere else – such as for the air-conditioning system and rear windscreen heating. And if your own safety or comfort is not impaired in any way. When the journey continues, the engine starts up again as soon as you take your foot from the brake. A comfortable way of saving fuel and protecting the environment.
The Auto Start Stop function is not available for the BMW 730i/Li and BMW 760i/Li.
