The transmission neutralizer function puts the transmission in neutral when the brake pressure reaches the pressure setting. The transmission is held in neutral until the brake is released. The transmission neutralizer switch is used to disable the transmission neutralizer function. The same switch is used in order to change the brake pressure of the transmission neutralizer function. The light on the transmission neutralizer switch is illuminated when the feature is disabled.Note: The bottom position is the DISABLED position. The center position is the ENABLED position. The top is the SET position. Depress the top of the transmission neutralizer switch and release the top of the transmission neutralizer switch in order to display the current transmission neutralizer value on the instrument cluster.
Start the engine.
Depress the top of the transmission neutralizer switch longer than 3 seconds. The display on the instrument cluster displays the brake pressure.
Push on the service brake pedal until the desired pressure is achieved. The pressure may be set to any level in the range of 400 kPa (58 psi) and 1999 kPa (290 psi).
Release the transmission neutralizer switch.
The switch will return to the center position. The transmission neutralizer function will be enabled at the current brake pressure.The instrument cluster will display the transmission neutralizer value.Note: Hold the switch in the SET position for 15 seconds without touching the brake pedal in order to reset the factory default value. The factory default value is 903 kPa (131 psi). If the switch is released in less than 15 seconds, the transmission neutralizer value will not change.Note: If the brake pressure is less than 175 kPa (25 psi), the display will read 0(zero).Depress the bottom of the transmission neutralizer switch in order to deactivate the transmission neutralizer function.
