● When shifting into or out of four-wheel drive while driving, do not stop shift lever movement midway. An incomplete shift may cause a clattering noise from the auto-locking hubs. Continued use of the vehicle with this noise may damage the hub lock. Drive in four-wheel drive to stop the noise. Shift to twowheel drive as described. For Automatic transmission models: When moving the transfer lever from 4H or 4L to 4L or 4H, you must always move it quickly through the N position. If you are slow to shift, the engine idle speed will allow the transfer gears to speed up and gear clashing will occur. Do not move the transfer lever from 4H or 4L to 4L or 4H, from 2H to 4L and from 4L to 2H with the engine turned off. Otherwise, you may have difficulty in moving the transfer lever to the desired position. Do not leave the transfer lever in the N position with the engine running. Stopping with the transfer case in the N position may cause gear grinding when selecting another gear. Changing the transfer case gear quickly and smoothly will eliminate this. 5-24 Starting and driving
