LIGHTING

NOTE: 

.

•

When checking the input signals (off, tail, low-beam or high-beam), turn the ignition switch to the "ON" 
position in order to disable the headlamp automatic-shutdown function. However, the titles on the 
M.U.T.-III screen will not be highlighted as this has nothing to do with actual lamp operation.

•

For checking item "HEADLAMP HI", the M.U.T.-III displays "OFF" on the item No.2 "DIMMER SW" when 
the headlamps are at high-beam. Therefore, the M.U.T.-III should display "ON" momentarily when the 
dimmer switch is operated.
