Refer to "Recreational Towing" in Section 5 of this manual. 4L Position This range locks the front and rear driveshafts together, forcing the front and rear wheels to rotate at the same speed. This range (4L) provides additional traction and maximum pulling power for loose, slippery road surfaces only. Do not exceed 25 mph (40 km/h). The 4WD Indicator Light (located in the instrument cluster) will illuminate when the transfer case is shifted into the 4L position. Shifting Procedure 2H to 4H or 4H to 2H Shifting between 2H and 4H can be made with the vehicle stopped or in motion. If the vehicle is in motion, shifts can be made up to 50 mph (80 km/h). With the vehicle in motion, the transfer case will engage/ disengage faster if you momentarily release the accelerator pedal after completing the shift. Apply a constant force when shifting the transfer case lever.
