						The system may be switched on but not ready to warn due to the following reasons:
- 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 traffic lane is too narrow or too wide.
 - The bend is too tight.
 - You have taken your hands off the steering wheel.
