City Safety when evasive action isnot possible
City Safety can help the driver by automaticallybraking the vehicle sooner if it is not possible tosteer out of a potential collision situation.
City Safety assists the driver by continuously try-ing to determine possible "escape routes" to thesides if a slow-moving or stationary vehicle aheadis detected at a late stage.
Your vehicle (1) cannot "see" any way of veering toavoid the vehicle ahead (2) and will attempt to auto-brake sooner
Your vehicle
Slow moving/stationary vehicle
City Safety will not trigger the auto-brake func-tion as long as the driver has a chance to avoid acollision by steering the vehicle.
However, if City Safety determines that an eva-sive steering maneuver is not possible due to alack of space in the adjacent traffic lanes, thefunction will attempt to assist the driver by auto-matically applying the brakes considerablysooner.

WARNING
City Safety's capacity to assess certain trafficsituations is a supplemental aid to the driverand does not function in all driving/traffic sit-uations or weather/road conditions. It cannever replace the driver
