Towing 2012 JGC Behind Motorhome : Procedural Question

New Owner who loves his 2012 JGC Overland V6 and is petrified of doing something stupid. (But I've towed an 05 Liberty behind my motorhome for years...)

So, I know how to put the vehicle in neutral in prep for towing four wheels down. That's been discussed.

Question: What is the proper procedure for getting the vehicle out of neutral for normal driving? Haven't been able to find that answer anywhere and naturally emails to Jeep/Chrysler go into a black hole.

Inquiring minds want to know and thanx in advance.

Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for normal usage.
1. Bring the vehicle to a complete stop, leaving it con- nected to the tow vehicle.
2. Firmly apply the parking brake.
3. Turn the key fob to the ON/RUN position, but do not start the engine.
4. Press and hold the brake pedal.
5. Shift the transmission into NEUTRAL.
6. Using the point of a ballpoint pen or similar object, press and hold the recessed transfer case N (Neutral) button (located by the selector switch) for four seconds, until the light behind the N symbol starts to blink, indicating shift in progress. The light will stop blinking (go out) when shift is complete. The “FOUR WHEEL

STARTING AND OPERATING 459
DRIVE SYSTEM IN NEUTRAL” message will no longer be displayed on the EVIC (Electronic Vehicle Information Center). Refer to “Electronic Vehicle Information Center (EVIC)” in “Understanding Your Instrument Panel” for further information.
Neutral Switch









460 STARTING AND OPERATING
NOTE: When shifting out of transfer case NEUTRAL NOTE:


(N), turning the engine OFF may be required to avoid gear clash.
7. Shift the transmission into PARK.
8. Release the brake pedal.
9. Disconnect vehicle from the tow vehicle.
10. Start the engine.
11. Press and hold the brake pedal.
12. Release the parking brake.
13. Shift the transmission into DRIVE, release the brake pedal, and check that the vehicle operates normally.
14. The Keyless Enter-N-Go button (if equipped) may now be reinstalled if desired. Refer to “Starting Procedures/Keyless Enter-N-Go” in “Starting and Oper- ating” for further information.

Steps 1 through 5 are requirements that must be met prior to pressing the NEUTRAL (N) button, and must continue to be met until the shift has been completed. If any of these requirements are not met prior to pressing the NEUTRAL (N) button or are no longer met during the shift, the NEUTRAL (N) indicator light will flash continuously until all requirements are met or until the NEUTRAL (N) button is released.
The ignition switch must be in the ON/RUN position for a shift to take place and for the position indicator lights to be operable. If the ignition switch is not in the ON/RUN position, the shift will not take place and no position indicator lights will be on or flashing.
A flashing NEUTRAL (N) position indicator light indicates that shift requirements have not been met.

Re: Towing 2012 JGC Behind Motorhome : Procedural Question

I have yet to order my 2012 Overland, but I have the same interest in towing it with my motorhome. My understanding is that with the Quadra-Drive system (standard on 2011 Overlands, but unfortunately only available with the off-road packages in 2012). I plan to order the ORII package at any rate, and, from what I understand, there is a simple neutral switch or push button on the console that prepares the vehicle for towing. Undoubtedly it's a bit more complicated than that, but I'll have to wait till I read the owner's manual to see if all of the above instructions also apply.

I have pulled three different cars over the years, and have always needed to use the Remco driveshaft-disconnect system for towing. It's good news that the Quadra Drive does not require using this system for towing.

There's no difference between the QTII and QDII systems in this respect. The little neutral button for the transfer case is right at the 12 o' clock position of the SelectTerrain knob. The procedure is as listed, and should be pretty simple.

Re: Towing 2012 JGC Behind Motorhome : Procedural Question

That's good to know. Thanks, Technosavant.

wm_j_ray, what towbar setup are you using , or planning to use, with your new Overland?

In a related matter, I was just reading about Roadmaster's new "InvisiBrake" aux. braking system for towed vehicles. Wow! What a simple setup, and a vast improvement over the clunky gizmos required in the past.

Re: Towing 2012 JGC Behind Motorhome : Procedural Question

I've used Blue Ox for years on the tow bar, an Adventia and have been very pleased. I previously had a Brake Buddy but am switching to Blue Ox Patriot system. Were I get away from a brake in a box system, I think I would go with US Gear UTB system.

Re: Towing 2012 JGC Behind Motorhome : Procedural Question

Hey all,

Just getting ready to install my Blue Ox 1128 kit on my Grand Cherokee Overland. I read this thread and the OM from Jeep about recreational towing.

One step left out in PWGUY's posting that is in the 2012 OM is the need to disconnect the Negative battery terminal on the battery before towing.

This is very odd to me as I have installed kits and towed 3-4 of my SUVs and never have needed to disconnect the battery. What is bad about this if it is required is my brake system needs 12volts to operate.

I am thinking this could be just a precautionary thing they want you to do to save power. My concern is they are doing this because of the Key and Go, locking steering wheel or other electronic reason.

Thoughts?

Re: Towing 2012 JGC Behind Motorhome : Procedural Question

Update for inquiring minds:
Talked to a professional installation company that said you are to disconnect the negative battery post as noted by Jeep OM and they install a 6 pin receptacle (not four) on Jeep grilling and run a 12v charge line from the moho to the Jeep battery to run your breakaway brake system (required by law in at least California). Otherwise if you are towing more than a few hours the battery will lose charge.

Anyone using a brake system inside and towed a long distance and had low battery charge or none?

Re: Towing 2012 JGC Behind Motorhome : Procedural Question

Did you ever get a response about the following Q you posted: "Anyone using a brake system inside and towed a long distance and had low battery charge or none?" I have the exact same Q regarding my 2011 Overland, which I've just had modified to use my Blue Ox Aventa. Am concerned as well that by not disconnecting the negative cable, the battery will lose charge over longer tows. In addition, by disconnecting the negative cable, assuming this turns off your electronic system, when the cable is re-connected, will it re-boot properly? Thanks. Griz

Re: Towing 2012 JGC Behind Motorhome : Procedural Question

I towed a 2008 Liberty behind my Motor Home for the last four (4) years. It states in the owner's manual to disconnect the negative battery cable - I never did. One explanation for the disconnecting of the negative battery cable was "just in case" something happened, the Jeep could not "switch back" to a "non-nuetral" state.

More recent explanations have been that the owner's manual was never changed to reflect that the negative cable did not need to be disconnected.

I have a 2012 Jeep GC on "order" - a dealer trade - and I do not plan on having to disconnect the Negative Battery cable when I tow.

I also have a charge line from the Motor Home to the battery (I guess it will be the "jump start" terminals to keep the battery charged. My braking system ties direct to the battery.

Michael

Arrow Re: Towing 2012 JGC Behind Motorhome : Procedural Question

I tow my 2011 JGC, sometimes for 6 - 8 hours, and have never disconnected the battery. In one place, my manual states to disconnect the battery, but in another place it doesn't state it in the towing instructions. No discharge on the battery. However, when towing at night, I did notice the interior lights came on and off. But I think that is part of my security system detecting the Jeep getting "bumped" driving on the road. I need to learn how to disable this security feature when towing. But again, it's never caused a battery problem.

I use a Roadmaster tow-bar attached to the motor home. The Jeep only has removable mounting brackets (in place of the tow hooks). I also use the Air Force One auxiliary brake system on the jeep, which is tied into the air brake system of the motor home.

We live and travel fulltime in our motor home, so we're towing the Jeep everywhere we go.

Re: Towing 2012 JGC Behind Motorhome : Procedural Question

I don't lock my Jeep going down the road. I figured if somebody wants to climb in and try and unhook and the like while I am travelling 60+ on the highway - more power to them. I lock it when I stop.

I use a Roadmaster Tow Bar also and I use the US Gear brake system.
