Obstruction warning

Hi everyone, I'm new here, but I'm hoping someone can help me with a very frustrating problem. While backing my trailer into my back yard, I had to drive over the curb and even in 4H the truck forces a stop and gives me an obstruction warning. The safety features in this truck have almost gotten me in a serious accident once and now they make towing a nightmare. Does anyone know how to remove the features or turn them off permanently? Any help would be appreciated. Thanks.

 

You need to turn off the Parking Support Brake feature. It's the button on the dash, left of the steering wheel, that has car backing into a cone symbol. A dash light will come on telling you that the feature is off. It will remain off permanently until you activate it again.

 

Thanks for the info. For further clarity, I had the selector in tow mode, parking sensors were all disabled in the dash settings. Basically I was slowly reversing to the curb then when I came in contact with the curb I tried to go over it. A message popped up on the dash saying obstruction warning and something about the truck not allowing me to accelerate. There shouldn't be any reason that a 4x4 truck in 4x4 mode shouldn't be able to crawl over a curb.
