The system is designed to provide assistance on motorways and other out-of-town roads, so it only operates at speeds above about 60 km/h.

WARNING

  • Х Please note that the sensors are not always able to detect all vehicles which may represent a potential hazard (accident risk).
  • Х Please note that the side assist is not able to give adequate warning of vehicles approaching very fast from behind, or vehicles that you are overtaking rapidly.
  • Х The radar sensor's "field of vision" can be impaired by rain, snow or a lot of water on the road. This results in vehicles not being reliably recognised or, in some circumstances, not being detected at all by the side assist. Always give your full attention to the position of your vehicle on the road and other nearby traffic.
  • Х The side assist only gives a warning of approaching vehicles and vehicles in the blind spots when road speed is above 60 km/h. Х Please note that the side assist does not operate in tight bends (with a radius of less than 200 metres).
  • Х The side assist feature is not a substitute for the full concentration of the driver. The driver is always responsible for the safety of lane changes and other manoeuvres. Always give your full attention to the position of your vehicle on the road and other nearby traffic.

Caution

  • Х To avoid impairing the function of the side assist, do not attach any objects (e.g. stickers or bicycle carriers) in such a way that they might interfere with the radar sensors in the rear bumper.
  • Х Make sure that the warning lamps on the exterior mirrors are not obscured by stickers or other objects.

Note

  • Х To ensure that the side assist function works properly, do not allow snow and ice to accumulate on the rear bumper near the radar sensors. Please observe the additional notes on.
  • Х The side assist function will be switched off automatically when the electrical connector for the trailer socket is plugged in on vehicles with a factory-fitted towing bracket.
  • Х The side assist should be switched off manually when towing a trailer if the vehicle is equipped with a towing bracket which was not factory-fitted.
  • Х The side assist system will switch off automatically if it detects an obstruction that impairs the function of the radar sensors.
  • Х The warning lamps on the exterior mirrors may not be properly visible if tinted foil is affixed to the side windows on the driver's or passenger's side.
