Palazzo (or any freightliner) - Chassis Suspension Height Lever
What is the intended behavior of the airbag height adjustment lever on the Freightliner XC chassis?
It says "lower" on the left, and "auto" on the right.
When I flip it to lower I hear air being released - but I have let it go for around 15 minutes and it hasn't stopped releasing air. I eventually switched it back to auto.
I also didn't see a significant ride height change, but I'm not sure how much is expected.
How is this supposed to work? I wasn't able to find documentation of the expected behavior in any of the chassis manuals I have.
Thanks in advance for any insight.
