attention necessary for safe  
driving. The driver is solely  
responsible for paying attention  
to their surroundings and oper-  
ating the steering wheel as nec-  
essary to ensure safety. Also,  
the driver is responsible for tak-  
ing adequate breaks when  
fatigued, such as when driving  
for a long time.  
Break suggestion function  
If the vehicle is swaying, a mes-  
sage will be displayed and a  
warning buzzer will sound to
