BMW 3 Series 2020-2023 Steering intervention User Manual
Depending on the equipment version: if, in the speed range up to 130 mph/210 km/h a lane marking is crossed, the system may intervene with a brief active steering intervention in addition to vibrating. The steering intervention helps keep the vehicle in the lane. The steering intervention can be noticed on the steering wheel and can be manually overridden at any time. During an active steering intervention, the display in the instrument cluster will blink.
Depending on the equipment version: in the event of multiple active steering interventions by the system within 3 minutes without the driver’s intervention at the steering wheel, an acoustic warning will sound. A short warning signal will sound at the second steering intervention. Be‐ginning with the third steering intervention, an continuous warning will sound. In addition, a Check Control message is dis‐played. The warning signal and Check Control message are an encouragement to pay closer attention to the lane.
End of warning
For instance, the warning will be canceled in the following situations:
- Automatically after a few seconds.
- When returning to your own lane.
- When braking hard.
- When blinking.
- The Dynamic Stability Control (DSC) adjusts.
The system is designed to operate in certain conditions and circumstances. Due to conditions or other factors, the system may not respond. There may be a risk of accident or risk of damage to property. Actively intervene as warranted. Refer to the information in this Owner’s Manual regarding the scope of the system’s operation and limitations.
System limits of the sensors
Cameras, refer to page 37.
The system may be limited in the following situations:
- In the event of missing, worn, poorly visible, merging, diverging, or multiple lane markings such as in construction areas.
- With lane boundaries that are covered in snow, ice, dirt or water.
- In tight curves or on narrow roads.
- With lane boundaries that are covered by objects.

A Check Control message may be displayed when the system is not fully functional.
Active Blind Spot Detection
Active Blind Spot Detection detects vehicles in the blind spot or vehicles approaching from be‐hind in the adjacent lane. The light in the exterior mirror warns the driver in different steps.
Radar sensors monitor the area behind and next to the vehicle when traveling faster than a mini‐mum speed. The minimum speed is country-specific and is displayed in the menu for the intelligent Safety systems. The system indicates whether there are vehicles in the blind spot, arrow 1, or approaching from behind in the adjacent lane, arrow 2. The light in the exterior mirror lights up dimmed.
Before you change lanes after setting the turn signal, the system issues a warning in the situations described above. The light in the exterior mirror flashes and the steering wheel vibrates. Vehicles with side collision mitigation: at speeds of up to 130 mph/210 km/h, the system can intervene with a brief active steering intervention and help guide the vehicle back into the lane. The steering intervention occurs when a mini‐mum speed is reached. This minimum speed is displayed on the Control Display in the menu for the steering intervention.
The system cannot serve as a substitute for the driver’s personal judgment in assessing visibility and traffic situation. There is a risk of accident. Adjust driving style to traffic conditions. Watch traffic closely and actively intervene where appropriate.
