Thank you for contacting the Jeep Customer Assistance Center.
I can certainly understand how confusing that can be of which is correct
for towing in your 2015 Jeep Cherokee.
I have done some research regarding this issue for you.
Since you do not have the tow package from the factory on your vehicle
it is only a max of 2,000 lbs. You can also double check with a
dealership as they will also know that information for you.
I hope this will help with the confusion for towing Dan.
Thank you again for your email. Should you require additional
assistance, or have any new information to provide, please reply to this
email message or call 1-877-I-AM-JEEP (1-877-426-5337).
