Towing hooks are intended only for freeing the vehicle from sand, snow, mud, etc. Never tow the vehicle using only towing hooks.
When freeing a stuck vehicle, the towing hooks are under a lot of stress. The towing rope should be pulled strictly forward or backward. Do not pull the hook at an angle to the vehicle.
CAUTION! Do not stand near the towing rope while towing.
