Engage 4WD on the Fly
The Jeep Wrangler is a versatile vehicle that can be used for both on- and off-road driving. One of the key features that makes the Wrangler so capable is its four-wheel drive (4WD) system. 4WD allows the Wrangler to transfer power to all four wheels, giving it increased traction in slippery or off-road conditions.
There are two types of 4WD systems available on the Jeep Wrangler: Command-Trac and Selec-Trac. Command-Trac is a part-time 4WD system, meaning that it can only be engaged when the vehicle is in motion. Selec-Trac is a full-time 4WD system, meaning that it can be engaged even when the vehicle is stopped.
To engage 4WD on the fly with the Command-Trac system, follow these steps:
- Make sure the vehicle is in 2WD and moving at a speed of at least 3 mph.
- Shift the transfer case lever into the 4H position.
- The 4WD indicator light on the dashboard will illuminate, indicating that 4WD is engaged.
| Steps | Description |
|---|---|
| 1 | Make sure the vehicle is in 2WD and moving at a speed of at least 3 mph. |
| 2 | Shift the transfer case lever into the 4H position. |
| 3 | The 4WD indicator light on the dashboard will illuminate, indicating that 4WD is engaged. |
Once 4WD is engaged, the Wrangler will be able to transfer power to all four wheels, giving it increased traction in slippery or off-road conditions. To disengage 4WD, simply shift the transfer case lever back into the 2WD position.
Shift into Neutral Before Engaging 4WD
Before engaging 4WD, it’s crucial to shift your Jeep Wrangler into neutral. This safety measure prevents any potential damage to the transmission or drivetrain.
Here’s a step-by-step guide on how to properly shift into neutral before engaging 4WD:

| 4LO | Engaged for low-speed crawling or maximum traction in extreme off-road conditions |
Avoid Engaging 4WD on Hard Surfaces
The primary reason to avoid engaging 4WD on hard surfaces, such as pavement or concrete, is that it can cause driveline binding. When 4WD is engaged, all four wheels are locked together, and they must rotate at the same speed. However, when driving on a hard surface, the wheels on the inside of the turn must travel a shorter distance than the wheels on the outside of the turn. This difference in speed can put stress on the driveline components and potentially cause damage.
On uneven surfaces, such as dirt roads or rocky trails, it is important to engage 4WD because it provides additional traction and control. However, it is still important to exercise caution and avoid engaging 4WD on hard surfaces. Even a small bump or pothole can cause the wheels to lose traction and potentially cause the vehicle to lose control.
When towing a heavy load, it is generally recommended to engage 4WD. This is because 4WD provides additional traction and stability. However, it is important to note that towing in 4WD can put additional stress on the driveline. Therefore, it is important to be cautious and avoid towing in 4WD on hard surfaces.
Engaging 4WD for extended periods can be harmful to the driveline. This is because the constant engagement of the driveline components can cause them to overheat. Therefore, it is important to only engage 4WD when necessary, and to disengage it as soon as possible.
Engaging 4WD can also reduce fuel economy. This is because the driveline components require more power to operate in 4WD than in 2WD. Therefore, it is important to only engage 4WD when necessary, and to disengage it as soon as possible.
In most Jeep Wranglers, 4WD High is the recommended setting for off-road driving. However, some drivers may be tempted to skip 4WD High and go straight to 4WD Low. This is a mistake. 4WD Low is a very low gear ratio that is only intended for extreme off-road conditions. Using 4WD Low on hard surfaces can cause driveline damage.
It is important to disengage 4WD before parking your Jeep Wrangler. This is because leaving 4WD engaged while parking can put stress on the driveline components. It can also make it difficult to turn the steering wheel.
Use 4WD Low for Steep Inclines and Severe Conditions
Selecting 4WD Low
Engage 4WD Low by shifting the transfer case lever to the “4L” position. This setting provides the lowest gear ratio and maximum torque, ideal for challenging off-road conditions.
Additional Considerations
When using 4WD Low, consider these additional points:
- Steep Inclines: Ascend and descend steep inclines slowly and steadily, using the lowest possible gear.
- Severe Conditions: Engage 4WD Low in extreme conditions, such as deep snow, mud, or rock crawling.
- Fuel Economy: 4WD Low increases fuel consumption, so use it only when necessary.
- Transmission Protection: Avoid using 4WD Low on dry pavement, as this can damage the transmission.
- Vehicle Stability: 4WD Low improves vehicle stability on rough terrain, but it is not a substitute for safe driving practices.
Suitable Situations
4WD Low is appropriate in situations where:
- Climbing steep hills with loose or slippery surfaces
- Navigating deep mud or snow
- Traversing rocky or uneven terrain
- Ascending or descending extreme slopes
- Encountering slippery or icy conditions
Consult Your Owner’s Manual for Specific Vehicle Instructions
It’s always best to refer to your owner’s manual for detailed instructions on how to put your specific Jeep Wrangler into 4WD. The steps may vary depending on the year and model of your vehicle.
10. Additional Considerations for Engaging 4WD in a Jeep Wrangler
