Indicator lights in the buttons show which setting you are in. The indicator lights will come on briefly when you turn on the ignition and one will stay on. If the lights do not come on, you should take your vehicle to your dealer for service. An indicator light will flash while shifting the transfer case. It will remain illuminated when the shift is complete. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting. If the SERVICE 4WD light stays on, you should take your vehicle to your dealer for service. See Service Four-wheel Drive Warning Light onpage 3-36 for further information. Shifting to 4LO To shift to 4L0, the vehicle's engine must be running and the vehicle must be stopped or moving less than 3 mph (4.8 km/h) with the transmission in NEUTRAL (N) or with the clutch pedal pressed for vehicles with manual transmission. The preferred method for shifting into 4LO is to have your vehicle moving 1 or 2 mph (1.6 to 3.2 km/h). Press and release the 4LO button. You must wait for the 4LO indicator light to stop flashing and remain illuminated before shifting your transmission into gear. If the 4LO button is pressed when your vehicle is in gear and/or moving, the 4LO indicator light will flash for 30 seconds and not complete the shift unless your vehicle is moving less than 3 mph (4.8 km/h) and the transmission is in NEUTRAL (N) or with the clutch pedal pressed for vehicles with manual transmission. After 30 seconds, the transfer case will return to the setting last chosen. Shifting to 4HI or AUTO 4WD Press and release the 4HI or AUTO 4WD button. This can be done at any speed, and the indicator light will flash while shifting. It will remain illuminated when the shift is complete. Shifting to 2HI Press and release the 2HI button. This can be done at any speed. 2-32
