A close examination shows five levers in this photo. From the lower left: The straight rod angling left is the high/low lever for the rear end. In the center, the lever with two holes angling right (and a similar flat bar lever without a hole on the far side) are hand brake levers. The lever with the black knob is the transmission gearshift lever. Immediately in front of the black-knob lever, and shorter (with a button on top) is the emergency brake lever.
