BMW X3 Owners Manual: System limits

Detection range The system's detection potential is limited.

Thus a warning might not be issued or be issued late.

E. g. the following situations may not be detected:

• Slow moving vehicles when you approach them at high speed.
• Vehicles that suddenly swerve in front of you, or sharply decelerating vehicles.
• Vehicles with an unusual rear appearance.
• Two-wheeled vehicles ahead of you.

Functional limitations The system may not be fully functional in the following situations:

• In heavy fog, rain, sprayed water or snowfall.
• In tight curves.
• If the driving stability control systems are limited or deactivated, e.g., DSC OFF.
• If, depending on the vehicle equipment version, the field of view of the camera in the mirror or the radar sensor is dirty or obscured.
• Up to 10 seconds after the start of the engine, via the Start/Stop knob.
• During calibration of the camera immediately after vehicle shipment.
• If there is constant blinding effects because of oncoming light, e. g., from the sun low in the sky.

Warning sensitivity The more sensitive the warning settings are, e.g. the warning time, the more warnings are displayed. However, there may also be an excess of false warnings.
