Your BMW's number 1 system objective is to ensure that your car will start when you push the ignition switch. The warning indicators are trying to tell you that the way your BMW's battery is being charged as you drive is not sufficient to fully charge the battery. During extremely cold weather, your warning light may come on even if your battery is fully charged no matter how you drive or charge your vehicle. If you are unable to fully charge your BMW's battery and it stays extremely cold outside, your BMW may not start somewhere down the line. That being said, we have not seen any vehicles reach that situation yet, even with the cold winter that we have been having.
If your warning light is on, We do recommend that you charge your battery fully. This can be done several ways.
- Driving your BMW at highway speeds for about 2 hours.
- Charge your BMW overnight with a battery tender or for 2 hours with a 30 amp battery charger
- Let your BMW Idle for about 4 hours.
Please remember to run as few accessories like seat heaters, defrosters, and the audio system during this process.
If you are able to do these things and your light is still on or if you have further questions, we are here to help.
