Engine brake

I have a 2010 Dutch Star, it has a Spartan frame 400 hp. Tomorrow will be my first time in some real hills mountains. The engine brake has a high off low, it has always been off. I tried reading manual but they didn't mention this type activation. Do I hit switch to low and high as needed or can I leave it in low or high? Thanks

The best advice I can give you is to turn it on and start using it, switch between high and low, and get use to using it. You will soon come up with a personal liking and when and how you like yo use it. Most leave it on all the time.

I agree with pale horse. Turn it on low and then high and practice with it under normal driving conditions. Then you will know what to expect. You can toggle it between HIGH and LOW to maintain speed. Once you get comfortable with it, you will have all the confidence to handle any mountain road. I was a little nervous when I went down my steepest one yet, going into Red River NM last summer. I never had to touch the service brakes and it held to 23 MPH with it on HIGH. The % gradient wasn't posted but it seems steeper than the few 8% grades I have been down.

I leave mine off and use 1 or 2 depending on how much stopping power I need. One of the reasons I leave it off is that I have followed other rvs that leave brake on and every time they let off accelerator pedal the brake light comes on, light off light on even though they are not really braking, like someone that rides their brakes in a car. Also I let the rv coast when ever possible, no fuel being used. It is your rv and you can do whatever you want.

You can leave the switch in an 'on' position all the time (except when/if driving on icy roads). If you take your foot completely off the accelerator, it will start to slow the coach using the engine and transmission downshifting.

The trick to being able to leave it in one of the 'on' positions at all times, is to not take your foot completely off the accelerator. If you leave your foot lightly on it (like depressing it 5-8%), the engine/exhaust brake will not come on.

I do like Kiawah, leve it on all the time (on low) and just feather the throttle if I don't want it to come on. This is especially helpful in town driving where there are stop lights and traffic. There are some instances when it turn it off but always back on when that has passed.
Also agree with Palehorse, practice with it on at verious speeds: engine brake on low and low spend and highway speed. Same with the engine brake on high. It doesn't take long to,get used to it and find who it works best for you.

Thanks to all, I found all this out yesterday. I think I will learn to feather the throttle around town.

I wish I had a 2 stage. Mine is either off or on. Around town I have to turn it off and manually turn it off and on. IMHO the low setting is for around town and in traffic. Maybe slight grades and the Hi is for long steep grades. Using it will let you get use to it and integrate it into your driving style.
