DASHBOARD INDICATOR LIGHT GUIDE
Your BMW communicates with you from the dashboard warning lights or dashboard symbols. Please note; the BMW dashboard lights below may differ in appearance between models.

As a general rule, the color of the illuminated symbol illustrates the severity of the issue.

Red: once illuminated indicates an issue that requires immediate attention.
Orange: will typically indicate a less urgent issue, for example a vehicle service required.
Other symbol colors such as blue and green provide the driver with information such as lights and indicators.
Flashing warning lights inform the driver of an urgent issue.

BMW dashboard warning lights should not be taken lightly. It's important to familiarize yourself with this guide. Contact your advisor at the BMW of Middleburg Heights Service Department with any questions or concerns.
