Lane departure warning

The lane departure warning in the BMW 5 VII generation warns the driver if the vehicle leaves the lane unintentionally. A front camera monitors the position of the vehicle between the lane markings. If the vehicle is detected leaving the lane without the turn signal being set, a steering wheel vibration is issued as a warning. The sensitivity and warning timing can be individually adjusted via the iDrive system. Especially on long motorway journeys or when driving is monotonous, the system helps increase attention and avoid accidents. A useful addition to active driving safety, day and night.

Principle

The lane departure warning alerts you when the vehicle is about to leave the lane on roads with lane boundary lines.

General

This camera-based system issues warnings above a minimum speed.

The minimum speed depends on the country and is shown in the menu for the Intelligent Safety systems.

The steering wheel begins to vibrate slightly during warnings. The timing of the warning may vary depending on the current driving situation.

The system does not warn if the turn signal is activated before leaving the lane.

Vehicles with side collision warning: If a lane boundary line is crossed in the speed range up to 210 km/h, the system additionally intervenes with a brief active steering input, in addition to the vibration, and helps keep the vehicle in its lane.

Safety information

WARNING The system does not relieve you of your own responsibility to assess the course of the road and the traffic situation. There is a risk of accident. Adapt your driving style to the traffic conditions. Watch the traffic and intervene actively in the relevant situations. Do not move the steering wheel unnecessarily forcefully when warnings are issued.

Prerequisites for operation

The lane boundary lines must be detected by the camera for the lane departure warning to be active.

   "My Vehicle"
2. 2
   "Vehicle settings"

Display in the instrument cluster

The symbol lights up green: at least one lane marking has been detected and warnings can be issued.

Warning Function

When leaving the lane

When leaving the lane and a lane marking is detected, the steering wheel begins to vibrate.

If the turn signal is activated before changing lanes, no warning is issued.

With side collision warning

If a lane marking is crossed in the speed range up to 210 km/h, the system intervenes in addition to the vibration with a brief active steering intervention, helping to keep the vehicle in its lane. The steering intervention can be felt at the steering wheel and can be overridden manually at any time.

When towing a trailer

If the trailer socket is in use, e.g. when towing a trailer or operating a bicycle carrier, no steering intervention takes place.

Cancellation of the warning

The warning is cancelled in the following situations:

• Automatically after approx. 3 seconds.
• When returning to your own lane.
• When braking hard.
• When the turn signal is activated.
• When DSC is controlling

System limitations

Safety information

WARNING Due to system limitations, the system may respond incorrectly or not at all. There is a risk of accident or property damage. Observe the notes on system limitations and intervene actively if necessary.

Functional restrictions

The function may be restricted, for example, in the following situations:

• In heavy fog, rain or snowfall.
• With missing, worn, poorly visible, converging or diverging, or unclear lane markings, such as at construction sites.
• When lane markings are covered by snow, ice, dirt or water.
• On sharp bends or narrow roads.
• When lane markings are not white.
• When lane markings are obscured by objects.
• When driving closely behind a vehicle ahead.
• With persistent glare from backlight, e.g. low sun.
• If the camera's field of view or the windshield in the area in front of the interior mirror is dirty or obstructed.
• During the camera calibration process immediately after vehicle delivery.

If the function is restricted, a Check Control message is displayed.

Sensitivity of the warnings

The more sensitive the warnings are set, the more warnings are displayed.

As a result, unintended warnings may also occur more often.

The lane departure warning of the BMW 5 Series G30/G31 helps the driver avoid unintentionally leaving the lane. A front camera monitors the road markings, and if a lane departure is imminent, a warning is issued in the form of a vibration at the steering wheel. Depending on equipment, a steering intervention helps keep the vehicle safely in its lane.

The individually adjustable sensitivity and the integration into the driver profile make the function particularly user-friendly. The system actively contributes to safety without relieving the driver of responsibility.

This keeps the BMW 5 Series G30/G31 a pioneer of modern assistance systems that noticeably relieve the driver in everyday driving.
