The SD85 has a battery cut-off switch again. It is located right beside the key. Please press this switch to set the electrics off and on again.

You also have the opportunity to switch off the retarder or alternatively the direct retarder. Please turn on both switches for example.

The additional gear selector switches allow you to limit the highest gear in the transmission can switch into. The default choice is position D, whereby the transmission will use up to 3 gears. For driving uphill, you can limit the highest one to 1 or 2 manually, if necessary.
