As JasonARJ3125 mentioned it's on the fuse panel just behind the drivers seat. In the top row of fuses there's one marked "AWS".
Can anyone tell me what the circle (indicator) means that is sometimes blinking with yellow stripes in the center desk? I activated AWS and TPWS.
Here's a handy resource on the AWS system: https://en.wikipedia.org/wiki/Automatic_Warning_System Basically, when the "sunflower" indicator is showing it's yellow stripes, you should be paying extra attention to your driving either because the signals are at caution or danger or there's a change in speed limit ahead etc... If all is clear ahead when you pass over an AWS magnet, the yellow stripes go away.
Like JasonARJ3125 said the Class 166 has it in a fuse cupboard behind the drivers seat whereas in the Class HST it is to the right of the driving position
