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

![]()  | Your car | 
![]()  | Oncoming vehicles | 
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
 - this function requires working Electric seatbelt pretensioners* (see section "Seatbelt pretensioner").
 
Note
The function uses the car's combined Camera and Radar unit, which has certain general limitations – see the sections "Limitations for Camera Unit" and "Limitations for Radar Unit" respectively.
Warning
- The "City Safety brakes for oncoming vehicles" function is supplementary driver support intended to improve driving safety – it cannot handle all situations in all traffic, weather and road conditions.
 - Warnings and brake interventions due to an impending collision with an oncoming vehicle always come very late.
 - The driver must never wait for a collision warning or for City Safety to intervene, but must instead brake with full force when danger is detected.
 - City Safety is not a substitute for the driver's attention and judgement. The driver is always responsible for ensuring the car is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
