Under certain conditions, the system can detect that the driver needs to take a break.
At the beginning of a trip, the system monitors the driver's general steering style. Using this as a reference, the system continuously compares the current steering input at speeds of between 65 km/h and 200 km/h. If the evaluation of the steering input implies a lapse in the driver's concentration, the system will then recommend a break ►Link.

is designed for journeys on motorways and major roads.System limitations
The rest recommendation function may misinterpret the steering input in certain driving situations, such as the following:
- On twisty roads.
- On rough roads.
- In poor weather.
- During performance driving.
- When the driver's attention is distracted.
Resetting the system
The system is automatically reset if you...
- switch off the ignition.
- release the driver's seat belt and open the driver's door.
- drive slower than 65 km/h for a while. If you subsequently increase your speed again, the system will reevaluate the driving style.
WARNING!
- Never drive when you are tired. As a driver you are always responsible for ensuring that you are fit to drive.
- On long journeys, make sure to take adequate breaks at regular intervals.
- The system cannot always tell if you need a break.
- In certain situations, the system may misinterpret driving manoeuvres and inappropriately recommend a break.
- No acute warning is given if the driver falls into a microsleep.
Note
The system is not available with all equipment versions.
