Indicator lamps
Ready: The indicator lamp lights up when the system is fully functional. The system is ready to intervene.
Not ready: The indicator lamp lights up when the system is switched on but not ready to intervene. The causes for this can include the following:
  • There are no lane markings.
  • The system cannot detect the relevant lane markings (e.g. temporary markings for road works or markings obscured by snow, dirt, rain or adverse light).
  • The vehicle's speed is below 65 km/h, the speed at which the lane assist system is activated (the threshold may vary in different export markets).
  • The lane is narrower than 2.5 m or wider than 5.5 m.
  • The bend is too tight.
  • You have taken your hands off the steering wheel.
  • Make sure that the camera window Fig. 2 is not covered with stickers or similar objects. Notes on cleaning Link.
  • On vehicles for some export markets: once the system is activated, it is "ready" each time the ignition is switched on.
