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.

The car analyses your driving behaviour and can detect signs of tiredness1. It then notifies you in the driver information area and with a sound.

The car uses different methods to assess your focus when driving.
Attention trackingSensor tracking of your face and eye movements allows the car to determine where you are directing your attention.
ManoeuvringAnalysing the way you manoeuvre the car can provide an indication of lacking focus. One example of this is excessive lane drifting.

Driver alert notifications can be turned off in settings. This does not disable the systems that monitor your driving as they are 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 sensor. 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.
  • 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.

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.
