    Driver behaviour detection

Driver alert

The car continuously observes your behaviour while driving and can alert you if you seem unfocused. A lack of focus can be caused by distractions or being tired.

If the car identifies signs of reduced driver focus, it will notify you with a sound and a message. In some situations, the car can also activate the driver seat massage and set the fan to maximum power to further emphasise the alert.

The car uses the driver behaviour detection system and its cameras to track your face and eye movements to determine where you are directing your attention.

Your car monitors certain aspects of your driving as well. Certain driving patterns, such as excessive lane drifting, may provide indications that the driver is tired or drowsy.

Driver alert notifications can be turned off in assist settings. This does not disable the driver behaviour detection system as it's also used by other features.

 Warning

The importance of a well-rested driver

Any notifications about you showing signs of being tired should be taken seriously, as a tired driver is often unaware of their condition. If you feel tired or receive an alert about it from the car, stop as soon as possible in a suitable location for a rest. Always plan for regular breaks and start all trips with a well-rested driver.

Driving while tired is comparable to driving under the influence of alcohol.

Conditions and limitations

  • Attention tracking requires an unobscured view of the driver's face.
    • Improperly stowed items can obscure the view of the driver, as can dust and dirt on the camera lens. Keep the driver's space clean and clutter-free.
    • Wearing certain clothing and accessories can obstruct parts of the driver's face that need to be visible for attention tracking, such as the eyes.
    • The steering wheel position, as well as your hands' placement on the steering wheel, can affect the camera's detection view.
  • Certain conditions can affect how well your car can assess your driving and manoeuvring. This in turn affects how well it can distinguish signs of an unfocused or tired driver.
    • Features that help with lane placement can sometimes compensate for manoeuvring that would otherwise indicate a lack of driver focus. This makes it harder to identify signs of lacking focus compared to unassisted driving.
    • Conditions such as strong winds or uneven road surfaces can affect your driving in ways similar to that of an unfocused driver. This can potentially cause warnings despite having a fully focused driver behind the wheel.

Read the separate section about conditions and limitations of your car's driver behaviour detection system and cameras to understand how features relying on these systems are affected.

 Important

Driver responsibility

Alerts about a lacking focus when driving are a supplement to safe driving practices. The driver is fully responsible for making sure they are able to stay alert and maintain focus when driving.
