Steering assistance upon risk of rear-end collision*
Steering assistance has a number of subfunctions. Steering assistance if there is a risk of rear-end collision can help a distracted driver who does not notice that the car is about to leave its own lane while an oncoming vehicle is approaching at the same time, either from behind or in the blind spot.

Other vehicle in the blind spot
Your car
If the car is about to leave its own lane while another vehicle is in the blind spot, or another vehicle is approaching rapidly in an adjacent lane at the same time, the function can help the driver to steer the car back into its own lane.
The function can even assist if the driver intentionally changes lanes using direction indicators without noticing that another vehicle is approaching.
The function is active within the speed range 60-140 km/h (37-87 mph) on roads with clearly visible lane markings/lines.
The lamps in the door mirrors flash during steering intervention, regardless of whether the BLIS1 function is activated.
After automatic engagement, the driver display indicates that this has occurred via a text message:
- Collision avoidance assistance Automatic intervention
