group 8, “General Safety Practices, Cab” before performing this procedure. If you are not
properly trained and certified in this procedure, ask your supervisor for training before you

interior, see Function Group 85.

brake, chocking the rear wheel, and placing the transmission in neutral.
2 Disconnect all cables from the negative (ground) and positive battery terminals to prevent
personal injury from electrical shock and prevent damage to electrical components.
3 If applicable, remove the transmission shifter panel.
