Four-Wheel Drive (4WD) System (If equipped) When you select the 4WD mode, your light truck uses all four wheels to power itself. This increases traction, enabling you to drive your 4x4 over terrain and road conditions two-wheel drive vehicles cannot. Power is supplied to all four wheels through a transfer case that allows you to select four-wheel drive when necessary. Methods for engaging and disengaging 4WD and low range will depend on which system your vehicle has. 4x4 Systems - Lever Operated The lever operated transfer case can be placed into four positions. The 2H position is the two-wheel drive position in which power is delivered only to the rear axle. The 4H position provides four-wheel drive with power delivered to the front and rear axles for increased traction. The 4L position provides four-wheel drive with power delivered to the front and rear axles when the above average power is required at reduced speeds. In the N (neutral) position, there is no power delivered to either axle. When the transfer case is in the N (Neutral) position, the engine and transmission are disconnected from the rest of the driveline. Therefore, the vehicle is free to roll even if the automatic transmission is in P (Park) or the manual transmission is in gear. 187
