MAN Truck: what do these indicators mean?

[Анатолий]

Sometimes i get these indicators. Usually it happens after parking using R1 and 1 speeds. Once it happened after i stopped in Hotel and slept. Usually they stop to alarm after some time. Truck does not to stop or shut off engine.

My guess that these are somehow connected to brakes. Is it right and do i need to do something when i get these?

Low air pressure warning.

You're using the pedal brake too much or are repeatedly turning on/off the parking brake.

What Reese's Cup said. And to fix it just rev your engine in neutral until your air pressure builds up again

Haha, I remember something funny when I had my extra driving lessons. The teacher told us to rev the truck while it just sat on the ground. But not too much, or it would seem very strange for that Scania making a lot of noise, because you wanted to fill up the air tanks on the truck faster. I don't think a lot of people would find it, uhh, comfortable with a truck making so much noise for ... nothing? In game I just push the pedal to the metal while the truck sits to fill up the air tanks and turn off the sound.
Ohh, and ask away if you need more info. My friends gets tired of my bla bla bla truck lessons, theory and whatnot. I can't help it as a real life truck driver.

Thanks for answers! That's something new for me. Need to say when i was driving Mersedes Actros i had no such problem. Only met it when i switched to Man.

Yes, i use pedal brake a lot when i do parking. Is there other options? I only play with cabin view without any synthetic mirrors and such. Only using keys 2 and 3 when i really stuck in parking/unparking (recently had a situation when unparking took me like 10-15 minutes because my trailer was really "hidden" between neighbouring trailer and ares borders).

Also what do you mean "rev your engine"? Sorry, not a driver in real life and having no experience with this.

To me looks like you turned on "Air brakes simulation" in Options -> Gameplay -> Truck settings a bit too early. Turn it off unless you did it intentionally. As you will feel more confident then don't hesitate to activate it again : )

About revs, it means to set your gear to neutral and accelerate. Depending on truck and its configuration will take more or less time to completely fill its air tank(s). But if you are using "Simple automatic" transmission type (same place as written above) you don't have the neutral gear available and this will leave you only one option: stop completely your truck and leave engine on for a lots of in-game time without to touch anything. If you change to "Real automatic" you can use the neutral gear, strongly suggested.

Of course to improve your driving and especially parking skill will help to avoid consuming too much air pressure, plus turning on "Automatic retarder" and "Automatic engine brake" will spare you some air pressure them too (assuming your truck is equipped properly for both to be used), but these are mainly for while you are travelling on the road at consistent speed rather than when manouvering in tight spaces.

Just throwing in - the indicator will always show up. Regardless if ABS is set to active or not unless they changed it since my last time i was not on active ABS (which is quite a while now). Main difference is, that in ABS active mode you get the indicator, plus a warning sound. And of course in case you don't react, the activation of the emergency brake system.

Should be still that way, the game always simulate it for the simple purpose to show data on the dashboard. If from game options it is setted off, one can ignore all of the stuffs, but if it is on, it is better to listen at those warnings.

@akanashin - About getting warnings after one sleeps, it happens when the truck is damaged. Altought I believe that wear damage won't matter (I never left it to grow too much), any impact damage will. Together with engine failure (randomly turns itself off) this is the only other one malfuction I ever experienced. Anyway, while engine failure will start to happens past 10% damage, air leak happens much before if not immediately after any impact. Difficult to be sure unless a direct experiment: go repair, crash the truck softly against the workshop wall, sleep there and see : D

[Анатолий]

Heh, cool!
Thanks for all the answers!

Yes, i have option "Air brakes simulation" on. Wanted to set as much realism as i can. Increased traffic events level and rain levels, decreased stability level for trailer, etc.... Also manual gear box (not sure though if this is real or not, have read that lately trucks are switching to automatic boxes).

Ok, i got the idea. Learning to dock using only real mirrors and getting better lately so i don't have this problem.
Thanks!

Keeping realism to max is the way to play this game. So yes, air on SIM setting. Trick to parking well is go dead slow. Than little need for breaks and higher chance to get it right first time.
