Shifting from Four-Wheel Low to Two-Wheel High or Four-Wheel High To shift from four-wheel low to two-wheel high or four-wheel high, your vehicle must be stopped or moving less than 1.2 mph (2 km/h) with the transmission in NEUTRAL (N) or the clutch pedal engaged. The preferred method for shifting out of four-wheel low is to have your vehicle moving 1.2 mph (2 km/h). Press and release the four-wheel high button. You must wait for the four-wheel high indicator light to stop flashing and remain illuminated before shifting your transmission into gear or releasing the clutch pedal. If the four-wheel high button is pressed when your vehicle is in gear and/or moving faster than 1.2 mph (2 km/h), the four-wheel high indicator light will flash for 30 seconds but not complete the shift. On vehicles with an automatic transmission, if your transfer case does not shift into four-wheel high, your transmission indicator switch may require adjustment. With your transmission in NEUTRAL (N), press and release the four-wheel high button. While the four-wheel high indicator light is flashing, shift your transmission into PARK (P). Wait until the four-wheel high indicator light remains illuminated before shifting your transmission into gear. Press the four-wheel high button again to complete the shift. This will get you into four-wheel high, but you should take your vehicle in for service to restore normal operation. 2-28 Shifting to NEUTRAL Use NEUTRAL when you plan to tow your vehicle. See Recreational Vehicle Towing on page 4-50 for towing instructions. To shift the transfer case into NEUTRAL do the following: 1. Set the parking brake. 2. Start the vehicle. 3. Shift the transmission in NEUTRAL (N), or press in the clutch for vehicles with a manual transmission. 4. Shift the transfer case to two-wheel high. 5. Press and hold the two-wheel high and four-wheel low buttons at the same time for 10 seconds. The NEUTRAL (N) light will come on when the transfer case shift to NEUTRAL (N) is complete. 6. Shift the transmission to REVERSE (R) for one second, then shift the transmission to DRIVE (D) for one second, or FIRST (1) for vehicles with manual transmissions. 7. Turn the ignition to LOCK. 8. Place the transmission shift lever in PARK (P), or FIRST (1) for vehicles equipped with a manual transmission.
