Before making WL and WH failsafe window adjustment:

Make a mental note of the gauge readings. the max should be ~5-6 bars. Adjust SC if necessary.

Set the WL to 8am and WH to 1pm. Drive the car and to test the WH, if there is failsafe activation, adjust WH few clciks clockwise. Repeat until no failsafe activation is noted. Add two extra clicks clockwise. WH is now adjusted

Now set the WL to 11am. adjust trimmer counter clockwise until no more activation occurs. Add two clicks counter clockwise.

Watch the road.
