Utilizing the Transfer Case
The transfer case in your Jeep Wrangler is key for sending power to all four wheels. It helps with traction and control on tough terrain. When you turn on 4WD, the transfer case shifts power to the front and rear axles for better performance.
To use the 4WD low (4L) range, follow these steps:
- Slow down your Jeep Wrangler to 2-3 mph.
- Put the transmission in neutral.
- Pull the 4×4 shifter from 2H or 4H through neutral to 4L (4-Low).
- Put the transmission back in drive and go slowly.
Using the 4WD low range gives you more traction and torque. It’s perfect for tough off-road situations like steep hills, deep mud, or water.
Jeep Wrangler owners can handle many driving conditions, including off-road adventures and tough winter weather, by knowing how to engage the 4WD system and use the transfer case correctly.
Operating in 4WD High vs. Low Range
Knowing the difference between 4WD High and Low is key for your Jeep Wrangler. The Jeep Wrangler terrain response system and 4×4 mode help you handle many terrains and conditions.
When to Use 4WD High
Use 4WD High for slippery surfaces like snow, sand, and mud at speeds up to 55 mph. It gives better grip and control, sending power to all four wheels. You can switch to 4WD High while moving, but slow down first to under 35 mph.

“Shifting into and out of 4L is possible while stopped but easier when in motion.”
Using your Jeep Wrangler’s 4WD High and Low correctly is vital for different terrains. Knowing when to use each helps you enjoy off-road adventures with confidence.
How to Disengage 4WD Safely
When you’re ready to leave the off-road trails and head back to the road, knowing how to operate a Jeep’s 4-wheel drive is key. Disengaging your Jeep Wrangler’s four-wheel-drive system requires a careful, step-by-step approach to prevent damage to the drivetrain.
Returning to Two-Wheel Drive
To turn off 4WD, first, slow down your Jeep Wrangler to a crawl and shift to neutral. Then, while moving forward slowly, push the transfer case shift lever up into the 4H position.
