Command-Trac (Part-Time 4WD):
* This system is for off-road use only and should *not* be used on dry pavement. Using it on pavement can damage the drivetrain.
* The transfer case lever will typically have positions like: 2H (2-wheel high), 4H (4-wheel high), and N (neutral). Some may also have 4L (4-wheel low).
* To engage 4H (4-wheel high):
1. Bring the vehicle to a complete stop. This is crucial.
2. Shift the transfer case lever to 4H. You may need to overcome some resistance.
* To engage 4L (4-wheel low):
1. Bring the vehicle to a complete stop.
2. Shift the transfer case lever to 4L. This will significantly reduce your speed and increase your torque.
Selec-Trac (Full-Time 4WD):
* This system allows for driving in 4WD on both paved and unpaved surfaces.
* The transfer case lever usually has positions like: 2H (2-wheel high), 4H Full-Time (4-wheel high), and N (neutral). Some Selec-Trac systems may also include a 4L position.
* To engage 4H Full-Time:
1. Shift the transfer case lever to 4H Full-Time. You can usually do this while driving at low speeds.
Important Considerations for Both Systems:
* Always engage 4WD before you need it. Don't try to engage it while driving at high speeds or on slippery surfaces.
* Avoid sudden acceleration or braking when in 4WD, especially 4L.
* If you hear any unusual noises or feel binding, immediately stop and check for problems.
* Consult your owner's manual for specific instructions and safety precautions for your particular Jeep Cherokee model. The location of the transfer case lever and the exact markings might vary slightly.
If you're unsure which system you have, carefully examine the transfer case lever and its markings. The owner's manual is your best resource for detailed instructions and diagrams.
