For example, the systems can help the driver to:
- maintain a set speed
- maintain a certain time interval to the vehicle ahead
- prevent a collision by giving a warning to the driver and braking the car
- help the driver to park.
Some of the systems are fitted as standard while others are options – which alternative applies is market dependent.
The functions are supplementary aids - they cannot handle all situations in all conditions.
The driver always bears responsibility that the vehicle is driven safely and that applicable road traffic rules and regulations are followed.
