BMW X5: Active Blind Spot Detection

Principle

Active Blind Spot Detection detects vehicles in the blind spot or vehicles approaching from behind in the adjacent lane.

The light in the exterior mirror warns the driver in different steps.

General information

Radar sensors monitor the area behind and next to the vehicle when traveling faster than a minimum 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 minimum speed is reached. This minimum speed is displayed on the Control Display in the menu for the steering intervention.

Safety information

Warning

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.

Warning

Indicators and warnings cannot serve as a substitute for the driver's personal judgment. Due to its limits, the system may not issue warnings or reactions, or these may be issued late or in a manner that is not consistent with their normal use. There is a risk of accident. Adjust driving style to traffic conditions. Watch traffic closely and actively intervene where appropriate.

Intelligent Safety

Sensors

The system is controlled by the following sensors:

• Radar sensors, side, rear.

Additional information: Sensors of the vehicle.

Turning on/off

Turning on automatically

Active Blind Spot Detection is automatically activated after departure if the function was switched on at the completion of the last trip.

Switching on manually

Press the button.

The menu for the Intelligent Safety system is displayed.

If all Intelligent Safety systems were switched off, all systems are now switched on.

"Configure INDIVIDUAL": depending on the equipment version, the Intelligent Safety systems can be individually configured. The individual settings are activated and stored. As soon as a setting is changed on the menu, all settings of the menu are activated.

Press the button repeatedly.

The following settings are switched between: "ALL ON": all Intelligent Safety systems are switched on. Basic settings are activated for the subfunctions.

"INDIVIDUAL": the Intelligent Safety systems are switched on according to the individual settings.

Some Intelligent Safety systems cannot be individually switched off.

Manual switching off

Press and hold this button.

All Intelligent Safety systems are switched off.

Button lights up green: all Intelligent Safety systems are switched on.

Button lights up orange: some Intelligent Safety systems are switched off or currently unavailable.

Button does not light up: all Intelligent Safety systems are switched off.

Warning function

Light in the exterior mirror

Prewarning

The dimmed light in the exterior mirror indicates when there are vehicles in the blind spot or approaching from behind.

Acute warning

When the turn signal is switched on while a vehicle is in the critical zone, the steering wheel vibrates briefly and the light in the exterior mirror flashes brightly.

The warning stops when the other vehicle has left the critical area or the turn signal has been deactivated.

Vehicles with side collision mitigation

When there is no response to the vibration of the steering wheel at speeds of up to 130 mph/210 km/h and the lane marking is crossed, the system intervenes with a brief active steering intervention. The steering intervention helps return the vehicle into the lane. The steering intervention can be noticed on the steering wheel and can be manually overridden at any time.

Flashing of the light

A flashing of the light during vehicle unlocking serves as system self-test.

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.

Upper speed limit

If the vehicle speed exceeds approx. 155 mph/250 km/h, the system is deactivated temporarily.

If the vehicle speed falls below approx. 155 mph/250 km/h, the system once again responds according to the setting.

System limits of the sensors

Additional information:

• Radar sensors
• On vehicles with side collision warning: cameras

Functional limitations

The system may be limited in the following situations:

• When a vehicle is approaching at a speed much faster than your own.
• In tight curves or on narrow roads.
• The bumper is dirty, iced up or covered, for instance by stickers.

For vehicles with side collision mitigation, the steering intervention can be limited, for instance in the following situation:

• 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.
• With lane boundaries that are not white.
• With lane boundaries that are covered by objects.
• When driving very close to the vehicle in front of you.
• If the camera is impaired.
• Up to 10 seconds after the start of the engine via the Start/Stop button.

A Check Control message is displayed when the system is not fully functional.

If the trailer power socket is occupied or trailer towing is activated, for instance during operation with trailer or bicycle rack, the system cannot be switched on. A Check Control message is displayed.

Displaying warnings

Depending on the selected warning settings, e.g., warning time, more or fewer warnings can be displayed. However, there may also be an excess of premature warnings of critical situations.
