New f350 with the exhaust brake button

[rtaylor0830]

I am confused is this a button you push when you want the exhaust brake to kick in or do you leave it on while towing. I do not have the truck yet, just been reading up on them.

Wow, sorta like the 'drive by' Media.

Tow haul raises the shift speeds. Engine brake on Ford closes the vanes on the turbo to cause back pressure. Ford does not have a valve in the exhaust line as some have had in the past. On my 2012 F-350 both features work at the same time when the tow haul button on the end of the shift is pushed. Separating it into two buttons was a VERY common suggestion, so Ford did it. The change in the 2015 turbo makes exhaust braking through vane control more effective in addition to supplying more air to compete better in mountain climbing contests. Some folks like the higher shift points without engine brake—with two buttons, now you can choose which one or both functions that you want to activate. If the engine brake button is on, the computer will decide when it thinks you want more brake effect and close the vanes. On the 2012, the computer will down shift and close vanes in an attempt to hold speed on a steep decent.

I leave mine on all the time during towing... It really does a good job.... As soon as you let off the pedal , it engages... Nice addition ...I think you will like it

You leave it on and it will come on when you let off the gas. IDK about the Fords but my Ram works good but different in normal and tow/haul mode. It is more aggressive in tow haul model.
