I'm not sure I'm reading the manual on my Monaco Windsor 40PBT right. I get the impression that I can leave the exhaust brake switch on all the time I'm driving and it will work any time I take my foot off the accelerator. I tried that today and it works great. Is that the correct way to use it?

Joe,

Yes, that is the correct way to use your exhaust brake with a couple of caveats.

1. Wet or slippery conditions.
2. Cruise control may not work at all or at least not well.

If the cruise will not set or if it causes the exhaust brake to engage unexpectedly then you may have to turn the brake off. If you do, just remember to turn it back on when appropriate. There is an after market switch available which makes it easier to use the exhaust brake with the cruise engaged. Google "RV exhaust brake switch" and see where it leads if you are interested.

Can you do that-- sure.

Will you loose my favorite "gear" COASTING-- yes.

Will you cause a lot of unnecessary down/up shifts-- yes.

Will your MPG suffer-- yes.

Do it or as many of us do, only leave it on in stop and go traffic, heavy traffic etc. Other times, only turn it on when you need it.

To leave it on in rolling hills on the road would drive me crazy with it downshifting and applying the exhaust brake every time you took you foot off the throttle after cresting a rise.

Play with it a bit and you'll find what works best for you.

I keep the jake brake off so the cc will function and just select low as my first choice than go to 2nd if needed, even toggle back and forth to control my descent. Most often, 2nd is simply too much braking except for short periods....kinda like throwing out an anchor.

Joe, there's nothing wrong with leaving it on all the time. You will get the feel of it quickly. Monaco has a lock out so the exhaust brake will not work with the cruise control on. I would not defeat that safety feature. JMHO...when activated, the transmission will automatically shift to either 2nd or 4th depending on how it's programmed. If it's programmed for 2nd and you'd rather have 4th it can be reprogrammed and visa versa, depending on your preferences. Where you will really appreciate it will be on long steep downhills. You should have a foot pedal also. If the switch is OFF and you activate the foot pedal, the brake will automatically activate as well. This is the mode I used to use with my Dynasty. (The Exec has a two stage Jake Brake, different animal) By leaving the switch on all the time, the tranny will continue to downshift whenever you take your foot off the throttle. This may be something you don't want happening all the time. Around town, my recommendation is to leave the switch OFF and use the foot pedal. On mountain grades turn it on because it's one less thing to worry about.....hope this helps....Dennis

Opinons vary.
Mine is not really. That mode is for when you are in heavy traffic or some other situation at low speed where you want to be able to and need to be in total control. It not only applies the exhaust brake but also causes the transmission to down shift a lot sooner than it would normally. Some people use tht mode also for exiting off ramps as it will apply the brake and downshift. I personally find that in that mode it downshifts way to soon and often for me.

My opinon that it should only be used tht way at low speeds or heavy taffic.

Ron,

Yes, I redesigned my Allison shift pad and exhaust brake switch location to a location where I did not have to take my eyes off the road to use them. A couple of inches to the left of the steering wheel.

Unless of course you are at "Highway" speeds....and a EMERGENCY situation suddenly developes in front of you, and the extra braking of the AUTOMATIC exhaust brake , would help you to get it slowed down sooner.

So, for obvious reasons....USE IT...Except in slippery situations. Drove HEAVY Firetrucks for Years....WE use exaust brakes.

The reason you do not want it in slippery situations.....is......the rear may stop with more force than the front, and come around.....having the front, behind the rear.....is a VERY BAD situation


USE it for what it was designed for .....read an owners manual....you know, the book with Instructions .....on how to use things..............by the people who designed them.

I bet You havn't had your coach for a long period of time,
Play with it, You will find what works for you.
Personally, I only use mine when I need retarding on grades.
Other times I dont like the unexpextected downshifts and retard when its not needed.
I expect, its not a BRAND related , rather than all of us that have a allison 3000 and a retarder.
What Brett said is pretty much on the mark, but after a few thousands miles of use you WILL be comfortable in its use and WHEN you want to use it.

MY BIG wish list, I would like to have the switch on my steering wheel, instead of reaching forward a few inches to the dash of my Winnie Journey to hit the retard switch.

I can now do it without taking my eyes off the road, but IT WOULD BE SOOOO NICE.
