Shifting into NEUTRAL To shift the transfer case to NEUTRAL, first make sure the vehicle is parked so that it will not roll: 1. Start the vehicle or turn the ignition to RUN. 2. Put the transmission in NEUTRAL (N). 3. Shift the transfer case to 2HI. 4. Simultaneously press and hold the 2HI and 4LO buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete. 5. Shift the transmission to REVERSE (R) for one second, then shift the transmission to DRIVE (D) for one second, for FIRST (1) for vehicles equipped with a manual transmission. 6. Turn the ignition to LOCK. Shifting Out of NEUTRAL To shift out of NEUTRAL: 1. Shift the transmission to NEUTRAL (N) and turn the ignition to RUN with the engine off. 2. Press the button for the desired transfer case shift position (2HI, 4HI, or 4LO). 3. After the transfer case has shifted out of NEUTRAL the red light will go out. Excessively shifting the transfer case into or out of the different modes may cause the transfer case to enter the shift protection mode. This will protect the transfer case from possible damage and will only allow the transfer case to respond to one shift per 10 seconds. The transfer case may stay in this mode for up to three minutes. All-Wheel Drive If your vehicle has the SS package, it may be equipped with all-wheel drive. With this feature, engine power is sent to all four wheels all the time. This is like four-wheel drive, but there is no separate lever or switch to engage or disengage the front axle. It is fully automatic, and adjusts itself as needed for road conditions. 2-48
