OPERATION

At key-on, overdrive operation is allowed. Pressing the switch once enables Tow/Haul mode and the Tow/Haul lamp will be illuminated. In Tow/Haul mode, 5th gear is disabled and 3-4 upshifts are delayed. Shifts into 4th gear are still allowed under steady cruise conditions. Closed throttle downshifts (for improved engine braking) may occur during steady braking maneuvers. Pressing the switch a second time enables OD Off mode, where all 4th and 5th gear operation is inhibited. Pressing the switch a third time restores normal operation. Normal operation is always the default at start-up; the switch must be pressed after each key start if Tow/Haul mode is desired.
