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

e.g. the warning time, the more warnings are
displayed. However, there may also be an excess
of false warnings.
Display
If a collision with a recognized vehicle is imminent
a warning symbol appears in the instrument
cluster and in the Head-Up Display.
