Overdrive Switch: Description and Operation
Tow/Haul Switch - Operation
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, 6th gear is disabled and 4-5 upshifts are delayed. Shifts into 5th 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 5th and
6th 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.
