9-48 Driving and Operating damaging the vehicle, always wait for the Four-Wheel Drive Low indicator light to stop flashing before shifting the transmission into gear. The vehicle may have significant engagement noise and bump when shifting between Four-Wheel Drive Low and Four-Wheel Drive High ranges or from N (Neutral) while the engine is running. If the knob is turned to the Four-Wheel Drive High, AUTO, or Two-Wheel Drive High switch position when the vehicle is in gear and/or moving more than 1.6 to 3.2 km/h (1 to 2 mph), the Four-Wheel Drive High, AUTO or Two-Wheel Drive High indicator light will flash for 30 seconds but will not complete the shift. With the vehicle moving less than 5 km/h (3 mph) and the transmission is in N (Neutral), attempt the shift again. Shifting into Neutral To shift the transfer case to N (Neutral) do the following: 1. Make sure the vehicle is parked so that it will not roll. 2. Set the parking brake and apply the regular brake pedal. See Parking Brake on page 9‑53 for more information. 3. Start the vehicle or turn the ignition to ON/RUN. 4. Put the transmission in N (Neutral). 5. Shift the transfer case to Two-Wheel Drive High.
