the system requires adjustment. See your MacDon Dealer.
2. With the engine shut down, steering wheel NOT centered, and the ground speed lever (GSL) in NEUTRAL, but
NOT in N-DETENT, try to start the engine. The cab display module (CDM) will flash “NOT IN NEUTRAL” on
the display upper line and “CENTER STEERI NG WHEEL” on the lower line, acco mpanied by a short beep with
each flash and the engine should NOT turn over. If the engine turns over, the system requires adjustment. See
your MacDon Dealer.
