Adaptive Cruise Control (ACC) -> Troubleshooting for Your Volkswagen Jetta 4 Door Seventh Generation (2019-2025)

WARNING  
ACC cannot detect all driving situations correctly. If the vehicle is less than the minimum distance from the vehicle ahead  
and the difference in speed between the vehicle ahead and your own vehicle is so great that the speed deceleration from  
the ACC is not sufficient, there is a risk of a rear end collision. This may result in serious injury or even death.  
Always be ready to apply the brakes yourself.  
To override the predictive cruise control and Adaptive Cruise Control (ACC), press the accelerator pedal. In this  
case, ACC will not brake automatically.  
Heed the country-specific regulations regarding minimum distance.  
Always set a longer distance when there is rain, snow, or poor visibility.
