Parking Brake Light on a BMW M3
Investigate soon. Driving short distances is generally okay, but book a diagnostic check.
What the Parking Brake Light Means on a BMW M3
The parking brake light on a BMW M3 shows the handbrake/electronic parking brake is applied. If it stays on after releasing the brake, it can also indicate low brake fluid or a brake system fault.
How Urgent Is the Parking Brake Light?
How worried should you be? For the Parking Brake Light on a BMW M3, the urgency is moderate. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing. If the BMW M3 still drives normally and the light is steady, you usually have time to plan a proper diagnosis; if performance drops or the light flashes, err on the side of caution and stop safely.

Is It Safe to Drive With the Parking Brake Light On?
Drivers ask this constantly, and the answer for the BMW M3 is nuanced.

Professional Mechanic Tips
Because this symbol doubles as a brake-fluid warning on many cars, check the reservoir before assuming it is just the handbrake switch.
