How do you use 4lo and 4hi in infinity qx56?

In the Infiniti QX56, the 4LO and 4HI settings are part of the vehicle's four-wheel drive (4WD) system. To engage 4HI, shift the transfer case lever to the 4HI position while driving at low speeds (up to 60 mph) for improved traction in slippery conditions. For 4LO, come to a complete stop, shift into neutral, then move the lever to the 4LO position for maximum torque and traction on rough terrain. Always refer to the owner's manual for specific instructions and guidelines regarding the use of these settings.
