Empty or Low Fuel
You have approximately 30 miles before you completely run out of fuel. Stop by a Poway gas station for a fill-up, as driving too long on low fuel can damage your fuel system.
Tire Pressure Monitor
If this light is triggered, it means that one or more of your tires is underinflated. If you see a yellow light, the tire pressure is about 10% low on air, while a red light indicates rapid deflation has occurred.
This symbol means your vehicle is due for an oil change soon. This is an essential part of regular maintenance, and not addressing it can cause severe engine damage.
If this symbol comes on, then one or more external lights are out or experiencing an issue. If the warning symbol is still on after you change out the bulbs, further investigation at a service center might be needed.
Your engine is getting too hot and potentially overheating; this can be both dangerous and damaging to your engine. If you aren’t near a BMW service center, we recommend you safely bring your car to a stop so your engine can cool down, and then visiting a service center as soon as possible.
When this warning light flashes or stays on, you will want to have your vehicle serviced immediately to have the powertrain system checked, as it means there is an issue with your engine or its components.
Dynamic Stability Control
This light isn’t one to worry about too much–it indicates that the traction control system has been engaged to regain control on a slippery surface. You can learn more about this feature in your owner’s manual.
