1. Identify Your Transfer Case:
* Command-Trac (Part-time 4WD): This system is only for use on low-traction surfaces like snow, ice, mud, or gravel. Do not use Command-Trac on dry pavement. Engaging it on dry pavement can damage the drivetrain. It typically has a lever on the floor console.
* Selec-Trac (Full-time 4WD): This system allows for 4WD use on all surfaces, including dry pavement. It usually has a rotary dial or a push-button selector.
2. Engaging 4WD:
* Command-Trac (Part-time):
* Before engaging 4WD: Bring the vehicle to a complete stop.
* Engage 4WD: Shift the transfer case lever to the "4 High" position. There might be a slight engagement sound or vibration. *Drive slowly and carefully.*
* Selec-Trac (Full-time):
* Engaging 4 High (4H): Rotate the dial or press the button to the "4 High" setting. This can be done while moving at low speeds.
* Engaging 4 Low (4L): You'll usually need to come to a complete stop to engage 4 Low. Look for a separate lever or button for 4L. 4 Low is for very low-speed, high-traction situations.
Important Considerations:
* 4 Low (4L): Use 4 Low only for situations requiring extremely low speeds and maximum traction, like steep inclines or deep mud. Avoid using 4 Low on pavement.
* Driving in 4WD: Avoid sharp turns and sudden acceleration or deceleration while in 4WD, especially 4 High. This can cause binding in the drivetrain.
* Consult your owner's manual: This is the most reliable source for information specific to your vehicle's 4WD system. The location and operation of the controls may vary slightly.
If you are unsure about your transfer case type or how to engage 4WD, consult your Jeep Cherokee's owner's manual or a qualified mechanic. Improper use of 4WD can damage your vehicle.
