the vehicle. When the obstacle is near, the  
"Danger" symbol is displayed.  
Audible assistance  
The proximity information is given by an  
intermittent audible signal, the frequency of which  
increases as the vehicle approaches the obstacle.

indicates the side on which the obstacle is located.  
When the distance between the vehicle and  
the obstacle becomes less than approximately
