BMW 7 Series: Front collision mitigation- System limits

Safety information

Warning

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.

Detection range

The system's detection potential is limited.

Only objects that are detected by the system are taken into account.

Thus, a system reaction might not come or might come late.

The following situations may not be detected, for instance:

• 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.

Upper speed limit

If the vehicle speed exceeds approx.

155 mph/250 km/h, the system is deactivated temporarily. When the vehicle slows down to below this speed, the system is reactivated.

Functional limitations

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

• In heavy fog, wet conditions, or snowfall.
• In tight curves.
• If the driving stability control systems are limited or deactivated, for instance DSC OFF.
• If the field of view of the camera or the windshield is dirty or covered in the area of the interior mirror.
• If the camera has overheated and been temporarily switched off due to excessively high temperatures.
• Up to 10 seconds after the start of the engine via the Start/Stop button.
• During calibration of the camera immediately after vehicle delivery.
• If there are constant blinding effects because of oncoming light, for instance from the sun low in the sky.
• When it is dark outside.
• Depending on the equipment: if the radar sensors are dirty or covered.
• Depending on the equipment version: after improperly performed work on the vehicle paint in the area of the radar sensors.

Attaching any objects such as stickers or film in the beam area of the radar sensors will also limit the function of the radar sensors and may even cause them to fail.

Warning sensitivity

The more sensitive the warning settings are, for example the warning time, the more warnings are displayed. Therefore, there may also be an excess of premature or unjustified warnings and reactions.
