Assistance at risk of collision in oncoming traffic

Assistance at risk of collisionCollision Avoidance can assist the driver to give steering assistance to avoid a collision with vehicles in the oncoming lane. The function can also reduce the speed of the car in order to reduce the force of an impact in the event of an encroachment into the car's own lane.

Meeting in own lane

If an oncoming vehicle enters your car's lane and a collision is unavoidable, the function can reduce the car's speed with a view to reducing the force of the impact.

For this function to work, the following criteria must be met:

  • your car must be travelling at more than 4 km/h (3 mph)
  • the road section must be straight
  • your car's lane must have clear lane markings
  • your car must be positioned straight in its own lane
  • the oncoming vehicle must be within your car's lane markings
  • the oncoming vehicle must have its headlamps switched on
  • this function can only handle "front to front" collisions
  • this function can only detect vehicles with four wheels.

When drifting across to oncoming traffic

The function can help a distracted driver who does not notice that the car is drifting into the oncoming lane.

The function can assist by guiding the car back to its own lane.

The function is active within the speed range 60-140 km/h (37-87 mph) on roads with clearly visible lane markings/lines.

If the car is about to leave its own lane while an oncoming vehicle is approaching at the same time, the function can help the driver to steer the car back into its own lane.

However, the function does not intervene with steering assistance if the direction indicator is used. If the function detects that the driver is actively driving the car, activation of the function will be delayed.

When the function intervenes, a symbol and a message are shown in the driver display, and an acoustic signal can be heard as well.

Warning

Warnings and steering assistance due to an impending collision with an oncoming vehicle always come very late.

Note

This function uses the car's camera and radar units, which have certain general limitations.
