Depending on road conditions the switch can be installed in situation NORMAL, PWR or HOLD mode for the movement in normal conditions, for the movement when the increased engine capacity, or for the movement without automatic gear shifting respectively is required.

By each pressing the switch button the operating mode of the transmission switches between the NORMAL, PWR or HOLD mode modes in turn.

Alarm lamps of the PWR and HOLD modes will light up and die away respectively.

In usual conditions the transmission has to work in the NORMAL mode when the button of the switch is not pressed. Alarm lamps of the PWR and HOLD modes will be switched off.
