How do I use the RESERVE SWITCH on my switch cluster?

This is the bottom row, to the far right switch. It feels like a momentary switch also.


when should I push it?

Push it when you want to change over to the reserve tank...usually when your tank goes empty. It should give you about 10% of the tank as a reserve.

How long do you have to push the button for? Thanks
