Stoping/Starting in 4WD

[PyrPatriot]

If you are driving in 4H or 4L while off roading and need to stop and turn off the vehicle, do you need to put it back into 2H?

I tried searching for the answer but results are improper because of the start/stop words confusing the algorithms to focus on the auto start/stop feature (Bing)

I did not know where else but General to ask as there isn’t really a subforum for inquiries on how to use Jeep features

No...you do not need to put it back in 2WD.

Start Stop - no different than regular ignition - Vehicle features and functions operate in same way. If automatic - just need to pop back in Park if shutting down. 6 spd - parking brake and pick a gear.

The better way to address this though - What is your concern with Start/Stop feature?

I think he was just saying that the start/stop feature, ie ESS, makes googling his question difficult. He was just trying to find out if he can turn the engine off while in 4h or 4L. At least, that’s how I read it.

yes that is exactly right

yes that is exactly right

For what it’s worth, I always put it back to 2H before turning engine off. No particular reason though.

Cool - just wanted to make sure there wasn't a deeper concern on function.

My concern is turning the engine off in 2H in a situation where I may not be able to get moving again to put it in 4H. Like stopping and parking on a mountainside in some mud. The stop will be long enough to warrant not running the engine

yep - no worries drivetrain selection isn't an issue in this case your good to go (leave the 4wd selector in whatever you need) Enjoy

I just read through the 4wd section of the manual and didn’t see anything concerning turning the engine off while in 4wd.

JT is my 4th Jeep and I have never had any issues in any of them turning off engine while in 4H or 4L.

No, it's perfectly fine to leave in 4H or 4L.

I hope that every person who drives a manual transmission Wrangler or Gladiator knows this: You can leave the vehicle in gear and not press the clutch in while cranking the starter in 4WD-Low. Yes, the vehicle will roll as the starter turns. There's a reason for that (if you drive a manual and didn't know that, that light has just come on, hasn't it?). And it's why any Jeep can be started in any gear (though usually the clutch pedal must be depressed in manuals).

Yes ESS works when in 4WD. Bugs the crap out of me. Follow someone and wait it shuts off.... LOL

Let's make this REALLY simple.
The one and only difference is that the drive-train is connected to the front wheels in 4H and 4L - otherwise all else is the same as far as the rear wheels.
The rest is still connected to the rear wheels in exactly the same way - no difference at all.

So when you shift to 4H or 4L all you are doing is adding the front wheels to the mix.
You are not disconnecting or changing how the rear driveshaft is connected in any way at all. You are only adding the front drive shaft.

4H adds the front drive shaft in a direct drive situation - no change in the speed into the transfer case vs. speed coming out.
If the output shaft of the transmission is spinning 1200 RPM, then both driveshafts will spin 1200 rpm.

4L adds the front drive shaft and gears both "down" - the output speed of both front and rear driveshafts are "geared down" by the transfer case.

N or neutral breaks the connection between both drive shafts and the output shaft of the transmission. Power from the transmission is not passed to the drive shafts, the vehicle can be towed or pushed and the rotating drive shafts won't impact the transmission as the motion will end in the transfer case.
