courtesy and boost buttons

I'm new to the world of RVs(I recently took on a 1987 Establishment as an affordable way to live through nursing school)-I'm still at the stage of wondering "What does that button do?" So on that subject, I have two buttons in the drivers dash area called 'courtesy' and 'boost'. What do they do??

On mine the courtesy button is to flash when someone gave you space to move over in front of them while passing or merging ect. The Boost button is to push when you run the chassis battery down too far and your engine won't crank. This will allow extra power to come the chassis batteries to assist with starting your engine.

Courtesy can have two meanings if it is an ON/OFF it's isle lights so people can see what they are stepping on.

If it's momentary then on my coach it says ICC and it flashes the marker/tail lights to say "Thank you" to a trucker (or other) who flashes you back into the right hand lane NOTE: I think mine only work when the taillights are on to start with.

BOOST Have you ever had a battery go low and needed to JUMP START the car? Well Motor homes have two independent (most of the time) Battery systems. House and Chassis.. IF the chassis battery is low and needs a BOOST often the house batteries can provide.

That button arranges it.. HOld for 30 seconds (no more) release for 30 seconds (Minimum) then press again and start the engine. (no more than 30 seconds of hold with 30-60 or more seconds between presses)

May also work to start the generator when house batteries are low.
