On automatic transmission equipped vehicles, if your transfer case does not shift into 4L0, your transmission indicator switch may require adjustment. With your transmission in NEUTRAL (N), press and release the 4LO button. While the 4LO indicator light is flashing, shift your transmission into PARK (P). Wait until the 4LO indicator light remains illuminated before shifting your transmission into gear. This will get you into 4L0, but you should take your vehicle in for service to restore normal operation. 2-30 Shifting from 4LO to 4HI or 2HI To shift from 4LO to 4HI or 2H1, your vehicle must be stopped or moving less than 3 mph (4.8 km/h) with the transmission in NEUTRAL (N) or the clutch pedal engaged.
