Disabling driver alert notifications is only temporary as this setting automatically resets to enabled between drives.
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.
Note
Driver responsibility
Alerts about a lacking focus when driving are a supplement to safe driving practices. They do not reduce the driver's responsibility to continuously assess whether they are too tired or unfocused to drive safely.
