Re: 2013 GC QuadtracII - Recreational Towing

You telling me. Before I cancelled my order I tried to get Jeep to confirm in writing that I did not have to remove battery cable or to clear up the discrepancy in the working and owners manual and got nothing but silence (no reply). Tried e mail and phone. They did confirm (in writing) that there is no steering lock on domestic vehicles but that was it. Do know that the new jeep sits on Mercedes frame and that may be the reason for all the changes but again no idea why they would not tell me why the need to turn ignition on then disconnect battery to tow vehicle. If you can find out Info please pass it on as I was unsuccessful.

Re: 2013 GC QuadtracII - Recreational Towing

I just went out and looked at the battery to verify this. It is really pretty simple to remove the negative cable. It does not require getting on one's hands and knees to accomplish.
If you move the passenger seat as far forward and raise the rear of the seat as high as it will go, the battery cover is exposed and there is plenty of room to work. Removing the cover is as simple as placing the fingers of one hand under the tab at the rear of the cover and pulling up firmly. The negative terminal is then exposed and can be removed with a 10mm wrench. Even a caveman can do it. The picture is attached. JeepBattery.jpg
I installed the Brakemaster 9160 for brakes and a Towdaddy device for the lighting. Both of those involve some wrenching, removal and replacement of interior trim panels, pulling wire and air hose, etc. It depends on how "clean" an install you want. I am pretty happy with the results.

Re: 2013 GC QuadtracII - Recreational Towing

So you are going to do this 80 or more times each summer. I leave Florida in June and will arrive back usually in October. I connect and disconnect at least 40 times. I have found that if something is more complicated than it needs to be I will simply keep my 2010 Jeep and avoid the hassel. That is why I used the M&G brake as it required one connection. This is why I do not use a tow dolly or a trailer. After running for 6 or so hours I simply want to disconnect my toad and park my rig and have a beer I do not want to fool with the battery. I own and build hot rods and love to work on cars but when I travel less hassel is the key. Messing with a battery is a deal killer for a toad. Stopping every 200 miles is also a deal killer and pulling a cb is also a deal killer. That is why I bought the Jeep. Where all I must do is put the transfer case in neutral, put the tranny in park and remove the key. Lights that I use are simply plug to the rig and done. I consider it a good trip when I do not have to use tools. I do hope that for whatever reason the new Jeep requires these extra procedures it will be corrected in the future. Until then I will avoid the 2013.

Re: 2013 GC QuadtracII - Recreational Towing

Man, when you think of it in terms of 80 times, it does get pretty significant. Not to mention the wear and tear on the connection. Hopefully we find out that disconnecting the battery cable is just some engineer overkill. I'll know in a week or so, anyway...

Re: 2013 GC QuadtracII - Recreational Towing

Thanks for your imput fourstar. I love my Jeeps and am hoping that the people who told me that it is caused by the main computer being turned on upon wheel rotation even with the ignition off are wrong. If I knew why they want you to disconnect I might be able to wire, fuse and switch the wire but if it is a softwear imput to the main computer then that is out of my pay grade. I am sure we will know more soon and when you do tow your new jeep (looks like a Summit ) please post as to what happens if you simply follow the 2012 recreational towing procedures. Does it record milage? Does it turn on the computer? If it does not do those things I will put my order back in for the 2014. Again thanks for your reply and the picture.

Re: 2013 GC QuadtracII - Recreational Towing

One more thing to consider when you disconnect the battery for rmore than a couple of hours are your radio and memory seat presets. I believe they are erased but not for sure. I also would consider the EVIC presets. I do not know if they return to default or not. Pretty sure radio presets will erase after a couple of hours. If you do not have to remove battery power one eliminates a large hassel factor me thinks.

Re: 2013 GC QuadtracII - Recreational Towing

Here are some questions that I posed to the service manager of a large Jeep Dealer in Jacksonville Florida prior to cancelling my order for a 2013 summit Jeep. It contains his answers. I hope this helps all you recreational towing guys with the 2013 Jeep. I tried to confirm with Jeep (factory and tek guys) but no luck. No reply to phone or e mail inquires as to the following was correct. These were sent via e mail.


1. Why do you have to turn the ignition to run ( removing start-stop button, inserting key and turning one notch) and remove negative battery cable in the 2013 and not the 2012?

Battery will drain and miles will be counted

2. If I pull the J-13 60 amp fuse rather than removing the battery negative cable as it states in the operating manual will it void the warranty?

Yes—if something is damaged as a result of this action

3. What would be the mechanical or electrical consequences of simply turning off the ignition and not removing the negative battery cable?

Battery drain and miles counted and it is possible that transaxle? could be damaged.

4. Is there a steering lock on the 2013 Grand Cherokee?

No.

5. After completing the procedures for flat towing the 2013 including pulling the negative battery cable can you turn the ignition off and remove the key? If feasible to do this would it void the warranty?

In itself, that will not void warranty unless something is damaged as a result.

6. Could a remote (actuator low amp switch in the passenger compartment) battery disconnect to the positive cable in lieu of pulling the negative battery cable be feasible. If so would this void the warranty?

That is fine and no warranty issues as long as there is room for it

7. By pulling the negative battery cable what memory (radio,seats,EVIC,etc) or random access memory would be affected.

Unknown

8. By pulling the J-13 60 amp circuit breaker what memory items or RAM would be affected.

Unknown

9. Is it possible if in fact the memory for certain functions on the car is affected by pulling the negative battery wire to run a separate wire to these functions? (example may be a hot fused wire to the memory on the seats,radio,etc.)

No

I have placed an order for a 2014 GC. So this information is helpful. The battery discharging might be overcome with a Toad Charger. Recording mileage is problematic and will require disconnecting the battery. I have found a battery disconnect switch that looks like a good product for about $125 that will disconnect the battery. Batteries Products

The Hitching Post told me they use a product called a Battery Brain to disconnect the battery.

If in fact the computer is recording mileage the battery will have to be disconnected. A number of my friends that are towing Buick Enclaves are using battery disconnect switches rather then pulling fuses because it is easier. It doesn’t seem to be a difficult install. I am looking forward to hearing your report. Thanks, Steve

Re: 2013 GC QuadtracII - Recreational Towing

I too am looking forward to galueck's report. I have friends that use a battery disconnect as well but they do lose after a couple of hours all the radio (including sirius) presets. possibly the memory seat functions as well but do not know for sure. I installed a speedometer disconnect on a Suzuki I had once as a toad and it worked well but may be illegal. I love the 2014 but will not order until I am sure it will work as a toad.

I hope you don't mind but I took your questions and answers and gave them to the service manager of Crystal Jeep here in Brooksville, Fl and below you will see his responses in italicized green. The original answers are in red.

I checked the 2014 GC Owners Manual and on page 475 it says the engine is in the off position. No where else in the Residential Towing section of the 2014 GC Owners Manual does it say the battery must be disconnected. I also checked the 2014 GC Users Guide and it was the same. I am left with the conclusion that the 2014 GC is different from the 2013. Does this mean that the changes to the 2014 manual are correct? Can the computers turn on if the ignition is in the "off" position? Can movement of the wheels cause the computers to turn on if the wheels turn and the ignition is in the off position? Hopefully "forestar" and "galueck" will be able to give us that answer once they complete their towing tests. Steve


1. Why do you have to turn the ignition to run ( removing start-stop button, inserting key and turning one notch) and remove negative battery cable in the 2013 and not the 2012? Battery will drain and miles will be counted

Page 474 of the 14 owners manual gives you complete instructions, no where does it mentions removing the start button, if i remember correctly the 13 has the option for key or button as the 2014 will be like the new RAM and does not have that option

2. If I pull the J-13 60 amp fuse rather than removing the battery negative cable as it states in the operating manual will it void the warranty?
Yes—if something is damaged as a result of this action

per my service manager, the fuses are designed to be removed and will not cause you to void the warranty

3. What would be the mechanical or electrical consequences of simply turning off the ignition and not removing the negative battery cable?

Battery drain and miles counted and it is possible that transaxle? could be damaged.

not applicable to 14 see page 474

4. Is there a steering lock on the 2013 Grand Cherokee?
No.

i have to assume no on the 14 based off the instructions in the owners manual

5. After completing the procedures for flat towing the 2013 including pulling the negative battery cable can you turn the ignition off and remove the key? If feasible to do this would it void the warranty?
In itself, that will not void warranty unless something is damaged as a result.

not applicable since disconneting battery is not mentioned for 14

6. Could a remote (actuator low amp switch in the passenger compartment) battery disconnect to the positive cable in lieu of pulling the negative battery cable be feasible. If so would this void the warranty?
That is fine and no warranty issues as long as there is room for it

not applicable since disconneting battery is not mentioned for 14

Re: 2013 GC QuadtracII - Recreational Towing

I'm going to follow the instructions in the 2014 Grand Cherokee Owner’s Manual on recreational towing.

Regardless, this does not mean I'm saying the Vehicle won't record miles and the computer won't turn on. If they do then the vehicle was specifically designed to record miles while being flat towed. Since, this would piss off every customer they are trying to please by making it towable, I doubt they would be that stupid to make this happen.
