    		Number of Times to Turn Low Beam Headlights on and off
    Fuel level is within range A.
    		1
    Fuel level is within range B.
    		2
    Fuel level is within range C.
    		3
    Fuel level is within range D.
    		4
    Fuel level is within range E.

    Blinks 6 times at 2 Hz → Blinks N*3 times at 2 Hz
    w/ Dynamic Headlight Auto Leveling:
    Blinks 2 times at 2 Hz → Blinks 3 times at 2 Hz, and then turns off.
    Removal and reinstallation of the headlight leveling ECU*1 or headlight swivel ECU*2, replacement of the rear height control sensor LH, removal and reinstallation of the rear height control sensor LH, replacement of the suspension, etc.
