3. No warning is given in the event of lane departure.
The Lane Alert and Optilane feature start to operate after two seconds of tracking road markings. So after passing a crossroads or an area without markings, the warning will be given after 2 seconds of tracking.
If you cross the line again while the warning message is active, the second warning message is deleted.
If the road is narrow, the sound signal is deferred, for the comfort of the driver.
Check that the video box activation threshold is at the correct level (sensitivity to acceleration in g). The Video Box records video images only if an acceleration greater than 0.4 g occurs in any direction.
Check the timing of the warning. If it is on the minimum setting, the driver may feel that the warning is too fast or occurs without any line being crossed.
In bad weather, or on roads under construction or roads where lines have been erased, guideo™ may not recognise the road lines properly.
