At European and the rest of the world markets, the rear self levelling suspension was only available standard on the W140s S 600, hence the headlight angle control was standard in all models.

The switch usually presents four settings: 0-1-2-3

0 - Standard (driver with or without a front passenger and with a full tank of gas).

1- Same as above plus a fully loaded rear seat.

2- Same as above plus a fully loaded trunk.

3- This position is recommended for heavy trailer towing.

The angle of aim is really dramatically varied, not just slightly.

By the way, the list above may differ from model line to model line. For example, my previous W123T (S123) 300TD Station Wagon presented the switch in this pattern: 1-0-1-2, where:

1 (above the cero) front passengers plus a fully loaded trunk, no rear seat passengers.

0 Standard

1 (below the cero) for fully loaded rear seat AND slightly loaded trunk.

2 Fully loaded car with or without a trailer.

I guess the self-levelling suspension on the T made the adjustment on the graphics. My W124 wagons all came with the regular 0-1-2-3 pattern.
