Part time” would mean it comes on automatically when wheel spin is detected, and shuts off when not needed. Therefore it’s okay to drive like that year round. I believe there is selector switch that allows the driver to override “part time” and have it on 100% during slippery, and only during slippery conditions.

Part Time 4 Wheel Drive (Part Time 4WD) – This refers to a four-wheel drive system that operates on-demand and drives all 4 wheels by locking the front and rear axles together via a shift lever. Full-Time 4WD (Full Time 4WD) – This is a four-wheel-drive system that can be operated continuously on all surfaces.

You can use Part-Time 4×4 as long as needed on slippery surfaces. Part-Time 4×4 4H or 4L locks the front and rear axles together for maximum traction and is best for off-road use. Full time 4×4 is for on road use, as in you can use it full time. Part time 4×4 should never be used on dry pavement.

Part-Time 4WD operates by default as a two-wheel drive vehicle. Unlike the full-time system, part-time 4WD doesn’t use a center differential. The system instead locks the front and rear driveshafts, making it better for use exclusively during off-road travel or challenging road conditions.

The light could mean a couple of things: It is possible you’ve engaged Part-Time 4WD and the light is just letting you know (it should be off if on dry pavement). Another possibility is you have a stuck transfer case indicator switch/sensor giving you a false indication light.

Sometimes it was due to a low tire and other times it was due to being too cold. Check the tires to make sure they are all inflated properly and with a warm Libby, try shifting out of Part-time. Sometimes I had to drive off road or over a curb to get it to kick out of Part-time.

Part-time 4WD is a vehicular system that allows the driver to turn on the 4WD only when needed. On regular driving surfaces without the 4WD engaged, it works just like a rear-driven 2WD vehicle.

To disengage your 4WD, slow down, put your Jeep in neutral and, while still rolling, push the lever firmly back to 4H. Put your Jeep back in gear and push the lever from 4H to 2H.

Slow the vehicle to two or three miles per hour if you must shift the transfer case to four-wheel drive low range. Shift you transmission to neutral then grasp the transfer case shifter. With the Jeep still coasting, shift the transfer case quickly from “4H” into “N” and from “N” into the “4L” position.

The Quadra-Trac I® 4×4 system works in what is called a “full-time high-range” mode. This means no driver input is required to distribute traction in any driving situation. Power is split with the help of the center differential: 48% is sent to the front axle and 58px is sent to the rear axle.

The Jeep Grand Cherokee , Cherokee , Compass, and Renegade all have Full Time 4×4 System. To put these vehicles into 4 Wheel Drive Low, shift into Neutral, press the 4wd Low button, and then shift to Drive.

Conclusion. Well, Jeep Cherokee is a full time 4 wheel drive. Therefore, putting it into 4 wheel drive low requires shifting into neutral then pressing the auto mode 4 wheel drive low button and shift to drive.

The 4WD system on a 2001 Jeep Cherokee is simple to engage. First You will need to put the vehicle in neutral while it is stopped and then You can select to engage four wheel drive high or low depending on what You need. This will engage the appropriate gears in the transfer case and allow You to use four wheel drive.
