BMW 3 Series 2018-2023 Owners Manual: Active Protection

Concept

Active Protection prepares occupants and the vehicle for a possible accident in critical driving or collision situations.

General information

Active Protection consists of various PreCrash functions, which can vary depending on the equipment.

The system is used to detect certain critical driving situations that might lead to an accident. This includes the following critical driving situations:

• Emergency stop.
• Severe understeering.
• Severe oversteering.

Certain functions of several systems can - within the system limits - lead to Active Protection triggering:

• Front collision mitigation: automatic brake intervention.
• Front collision mitigation: Brake Assistant
• Rear collision preparation: detection of imminent rear collisions.

Safety information

Warning The system cannot serve as a substitute for the driver's personal judgment. Due to the system limits, critical situation could not be detected reliably or in time. There is a risk of accident.

Adjust driving style to traffic conditions. Watch traffic closely and actively intervene where appropriate.

Function

When the safety belt is fastened, the driver's and passenger's belt straps are automatically tightened once after driving away.

In accident-critical situations, the following individual functions become active as needed:

• Automatic pretensioning of the front safety belts.
• Automatic window closing up to a narrow gap.
• Automatic closing of the glass sunroof, including sun protection.
• For vehicles equipped with comfort seats in the front: automatic positioning of the backrest for the front passenger seat.

After a critical driving situation without an accident, the front safety belts are loosened again.

If the belt tension does not loosen automatically, stop the vehicle and unbuckle the safety belt using the red button in the buckle. Fasten the safety belt before continuing on your trip.

All other systems can be restored to the desired setting.
