Multi-screwdriver, 10,12,14,17 MM wrenches, adjustable wrench, zip ties, e-tape, tire plugs kit, cotter pins, valve stem tool..if the bag was big enough I'd drop in a 3/8 ratchet with a couple of wobble extensions, 8,10,12,14,17,19 mm sockets, and an adapter to 1/2 drive for a 20,21,and 22 mm socket.

I'll think of more and edit later. But there ain't much you cant fix on a Toyota with the above stuff.

If Mad Max had a 4runner...
