OPERATION
On vehicles equipped with automatic transmissions, the park/neutral switch indicates if the transmission is in NEUTRAL, PARK, or a DRIVE
GEAR.
Based on input from this switch the electronic controller will determine speed control strategy. If the vehicle driver shifts the transmission into
NEUTRAL while the speed control is being used, the electronic controller will disable the speed control system. If the transmission is shifted back
into a DRIVE GEAR, the speed control will have to be reset.
