Operation

• The 2004-2005 Duramax has three high idle speeds available, 800 rpm, 1200 rpm and
  1800 rpm. To operate the high idle, the engine must be running, transmission in park, foot
  off of the brake and parking brake set. Turn the toggle switch on to start high idle. The
  engine will now increase from its normal idle speed to 800 rpm. To access the higher
  speeds, turn on the cruise control and press either SET or RESUME/ACCELERATE.
• Pressing SET (button on the end of the stalk) will yield 1200 rpm, pressing RESUME (one
  click past the on position) will yield 1900 rpm. To stop the high idle, simply turn the toggle
  switch back off.
• Do not leave the high idle switch on while driving.
• The idle speeds may be adjusted using a Tech2 factory scan tool. The above engine
  speeds are the default values and will suffice for normal extended idling, high idle and PTO
  applications.
