City Safety™

City Safety can alert the driver using a visual, acoustic and brake pulse warning to help him/her detect pedestrians, cyclists, larger animals and vehicles that suddenly appear - the car then attempts to brake automatically unless the driver acts within a reasonable time him/herself.

City Safety can prevent a collision or reduce collision speed.

City Safety is an aid to assist a driver who is at risk of colliding with a pedestrian, large animal, cyclist or a vehicle.

The City Safety function can help the driver to avoid a collision when driving in queues, e.g. when changes in the traffic ahead, combined with a lapse in attention, could lead to an incident.

The function helps the driver by automatically braking the car in the event of an imminent risk of collision if the driver does not react in time by braking and/or swerving.

City Safety activates a short, sharp braking procedure, normally stopping the car just behind the vehicle in front.

City Safety is activated in situations where the driver should have started braking earlier, which is why it cannot help the driver in every situation.

City Safety is designed to be activated as late as possible in order to avoid unnecessary intervention.

The driver or passengers are not normally aware of City Safety - it only intervenes in a situation where a collision is immediately imminent.


  • The City Safety is supplementary driver support intended to improve driving safety – it cannot handle all situations in all traffic, weather and road conditions.
  • The City Safety auto-brake function can prevent a collision or reduce collision speed, but to ensure full brake performance the driver should always depress the brake pedal – even when the car auto-brakes.
  • The warning and steering assistance are only activated if there is a high risk of collision – you must therefore never wait for a collision warning or for City Safety to intervene.
  • The warning and brake intervention for pedestrians and cyclists are deactivated at vehicle speeds exceeding 80 km/h (50 mph).
  • City Safety does not activates any auto-brake functions in the event of heavy acceleration.
  • 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.
  • The driver is advised to read all sections in the Owner's Manual that relate to City Safety to learn about factors such as its limitations and what the driver should be aware of before using the system (see the list of links for all subsections).
