GMC 1994 Yukon Owner's Manual page 245

If you ever get stuck in sand, mud, ice or snow, your vehicle may be
equipped with recovery hooks. The recovery hooks are provided at the front
of your vehicle. You may need
to use them if you're stuck off-road
and
need to be pulled to some place where you can continue driving.
A
CAUTION:
The recovery hooks, when used, are under a lot of force. Always
pull the vehicle straight out. Never pull on the hooks at a
sideways angle. The hooks could break off and you or others
could be injured from the chain or cable snapping back.
