Drive a auto box and this won’t happen

If you’re Going down hill not on the power, will an auto shift up at max revs or will it overspeed the engine?

On my auto Merc, it starts beeping at you when a downhill takes the revs into or near the red at all.
You have to change up, or more likely brake to bring your speed and revs down.
I haven’t left it to see what happens if you don’t do anything. I figure that, as the driver, doing something is what I’m there for :smiley:

Mine beeps at random times , drops into Neutral at will then beeps but I guess as its done 240000 kms and its a Spatstros its going to seed fast. :wink:

Yours must have been abused when it was young.
Mine behaves itself fairly well most of the time and its on about 350,000 :smiley:

650,000kms on a 58 plate Actros , behaves itself most of the time, jumps in to Neutral when fully freighted after changing down for a hill - Not Fun

That bleep is to tell you that the retarder is almost at full output. You get a second one to say it is at full bore, so if you want to slow it anymore you need to use the breaks. It is perfectly safe to go from the top to the bottom of a hill with the bleep on

I think I’ll just carry on doing what I’m doing thanks.
It’s a Merc, not an ovloV :slight_smile:
Besides, the handbook mentions 2500, the red line starts at 2500 and it beeps at 2500.
I think 2500 is getting the revs up high enough :smiley:

You can do what you like Simon. I was just telling you what the beep was for :wink:

It was abused from a early age :blush:

Although I fear that the main problem is not with the truck itself but by the sometimes random servicing by the local Mecedes dealership :wink:
