Which?
The Red P is parking brake, although could be a braking fault.
The Yellow is that the centre axle is lifted.
If you’re empty, make sure it’s lifted. Saves fuel, drag and tyre wear.
It’ll lower when weight on the fifth wheel exceeds around 8t, I believe it can be overridden and lifted for traction under about 8mph. Other than that, it’ll do it’s job without input.
Good luck out there, take it steady

You also don’t want the mid lift down in greasy or wet conditions when it can be lifted.
