Functionality may also be reduced in other situations, such as:
- road work
- winter driving conditions
- narrow roads
- poor road surfaces
- a very sporty driving style

In these demanding driving conditions, the function may not be able to properly assist the driver. In these situations, it is recommended that it is turned off.

Note
The function uses the vehicle's radar unit, which has some general limitations – see the section "Radar unit limitations".
