That would be your air pressure warning light. It means that there is a low amount of air in you pnuematics (I think that's spelled right) system. If you have air brakes simulation turned on, you will get an alarm when that light is on and your truck won't be able to move. That would be your air pressure warning light. There are a lots of realistic features with the mod. You will get Hyundai UXN model from 2016 to 2021. Bus Details: Body : Universe Noble Interior: RHD Chassis: 4×2 Engine: 409hp Transmission: 5 Forward Gear(Automatic Retarder) This mod will supported on 1.42+. Dealer: MAN/Scania. Thought it might be a modded one, but seems not. If on automatic, well, as Nono54Fr says, check you don't have the retarder on (game should warn you about that, though). The truck doesn't matter. ANY truck in the game will go faster than that with any load. It's the retarder that's stuck, turn it off. Look for Retarder higher, and retarder lower in key config. I mapped them to pgup and pgdn respectively. You should lower it. 1. its not a racing car. 2. make sure you are not in Neutral. 1. its not a racing car. 2. make sure you are not in Neutral.

I've done a pretty thorough (I think) search of the boards and wasn't able to find an answer. pieperjohanns Aug 17, 2017 @ 12:49pm. The exhaust/engine brake is now applied automatically together with the retarder, so you can't use the retarder separately anymore. At least that's how it works in the newer Volvo now (haven't tried the other trucks). #1. Enichelle ^_^ Aug 17, 2017 @ 12:51pm.

I accidentally turned the retarder on somehow and I get occasionally notified that it is on. The keybindings show a key for this: ACUTE/CEDILLA - `where is this key? Not sure how to explain this strange new behavior. I've been driving the new MAN TGX for 50+ hours and only just tonight noticed that it's slowing me down automatically when cruise control is on. I'll set cruise control to 50 km/h, speed up to 70, and about a second later it drastically brakes me down to 50 again. I don't have a retarder on this truck and the automatic retarder setting in VvWCp.
