BMW X5: Lane departure warning

Principle

The lane departure warning alerts when the vehicle is about to run off the road or exit the lane.

General information

This camera-based system warns starting at a minimum speed.

The minimum speed is country-specific and is displayed in the menu for the intelligent Safety systems.

Warnings are issued by means of a steering wheel vibration. The severity of the steering wheel vibration can be adjusted.

The system does not provide a warning if the turn signal is set in the respective direction before leaving the lane.

Depending on the equipment version, if in the speed range up to 130 mph/210 km/h a lane marking is crossed, the system may intervene with a brief active steering intervention in addition to vibrating. The system thus helps keep the vehicle in the lane.

Safety information

Warning

The system cannot serve as a substitute for the driver's personal judgment in assessing road and traffic situation. There is a risk of accident.

Do not jerk the steering wheel in response to a warning.

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.

Functional requirement

The camera must detect the lane markings for the lane departure warning to be active.

Display in the instrument cluster

The icon illuminates green: at lane marking was detected on at least one side of the vehicle and warnings can be issued.

Warning function

If you leave the lane

If you leave the lane and if a lane marking has been detected, the steering wheel vibrates in accordance with the steering wheel vibration setting.

When the turn signal is switched on in the corresponding direction before changing the lane, a warning is not issued.

Steering intervention

Depending on the equipment version: if, in the speed range up to 130 mph/210 km/h a lane marking is crossed, the system may intervene with a brief active steering intervention in addition to vibrating. The steering intervention helps keep the vehicle in the lane. The steering intervention can be noticed on the steering wheel and can be manually overridden at any time. During an active steering intervention, the display in the instrument cluster will blink.

Warning signal

Depending on the equipment version: in the event of multiple active steering interventions by the system within 3 minutes without the driver's intervention at the steering wheel, an acoustic warning will sound. A short warning signal will sound at the second steering intervention. Beginning with the third steering intervention, an continuous warning will sound.

In addition, a Check Control message is displayed.

The warning signal and Check Control message are an encouragement to pay closer attention to the lane.

With trailer towing

If the trailer power socket is occupied or trailer towing is activated, for instance during operation with trailer or bicycle rack, no steering intervention takes place.

End of warning

For instance, the warning will be canceled in the following situations:

• Automatically after a few seconds.
• When returning to your own lane.
• When braking hard.
• When blinking.
• The Dynamic Stability Control (DSC) adjusts.
