Tow/Haul mode question
 
I have a 2011 Overland Hemi. TSBs for smoother gear shifting and shuddering problem have been applied. I noticed that when driving in Tow/Haul mode, the gear indicator shows "5."

My question is: Is there any mechanical difference between using Tow/Haul mode and just tapping the shifter to the left to go from "D" to "5"?

I also noticed that at highway speeds engaging the Tow/Haul mode causes a change in RPMs, indicating a gear shift.

Thanks!

Tow/Haul causes overdrive to be deselected. It holds gears longer, and revs up a bit more before shifting into the next highest gear.

Gives quicker throttle response.

It also engages engine braking on down hills instead of free wheeling.

Pretty clever button.

When not in tow/haul, just tapping the shifter leaves you in 5th gear but disables the MDS. In tow/haul, it moves all the gears down by one, so 5 is actually the previous 4th etc.
Since the trans has 2 2nd gears, it uses the lower one for tow haul. Confusing, but it works well in practice. 4th and 5th are both overdrive gears.

can some one advise when towing a caravan 2500kg should i be using the tow haul mode or just leave it in normal mode, and does it have any effect with fuel consumption?


Cheers

Id put it in tow mode when towing anything. The manual suggests it for mountain driving as well.

When I tow a trailer of that weight on a flat highway at 70 mph I get 9.5-10 mpg with the tow/haul enabled.
