When I'm at stop lights, the engine shuts down (to save gas?) and then when I step on the gas, it turns back on. Its annoying as hell. How do I shut this off?
That's the start-stop function. The full explanation from BMW:
Auto Start-Stop Function
The idea is simple: when you stop, so will your engine.
Red lights, long trains, traffic jams, road work. There are countless instances when your engine unnecessarily uses fuel while your vehicle is not in motion. With the intelligent Auto Start-Stop function-an innovation developed as part of BMW EfficientDynamics-your BMW is designed to not only reduce fuel consumption, but also lower emissions so your engine can automatically turn off when it's not needed, and restart when it is.
Auto Start-Stop is managed by a central control unit that monitors the battery.
To ensure passenger comfort and safety, Auto Start-Stop is only active when certain conditions are met. These include, but are not limited to:
– An adequately charged battery
– An engine at the ideal operating temperature
– Fully closed doors
– Fastened seatbelts
I suppose you could unbuckle to prevent it from stopping the engine!
