My Dutch manual clearly states otherwise: the towhook can be used in emergency's, for instance towing out of the snow.
The car came with two towhooks, a short and a long one.
The big difference here is the sueing culture in the US. The manufacterers don't want to be sued when someone damage his car using the towhook. Not everebody does this in the right way, when this leads to damage, it is easy to say that the manufacterer constructed it wrong.
Imagine someone not using a winch on a towtruck but a large V8 pickup truck with a chain trying to pull someone out.
It is clearly not the right way, but many Youtube videos prove otherwise unfortunately.
When the towtruckcompany uses the mounts for tying down the car it is their responsibility if the car gets damaged.
I think if you can get a hold on a towhook, and pull in a staight direction you can safely get the car out without a problem.
