Check if warning light (5) is on when switching from double or crab steering to standard steering: it shows the regular alignment of rear wheels. DOUBLE STEERING: with this type of steering both front and rear wheels steer in the same direction (a smaller steering radius is obtained). With selecting switch (1) in position , warning light (3) lights up.

CRAB STEERING: with this type of steering, front and rear wheels steer in an opposite way (cross-transfer is obtained). If selecting switch (1) in position , warning light (4) lights up.
