The 2018 Jeep Wrangler is famous for its rugged 4WD system, making it a top choice for drivers who love adventure or need extra traction in tough conditions. Many people buy a Wrangler because of its off-road abilities. But if you’re new to this vehicle, or new to four-wheel drive in general, you might wonder how to engage the 4WD properly. Understanding this process is important, because using 4WD at the wrong time or in the wrong way can cause damage or leave you stuck. In this guide, you’ll learn step-by-step how to put your 2018 Jeep Wrangler in 4WD, plus practical tips, common mistakes, and answers to frequent questions.
Understanding The Jeep Wrangler 4wd System
The 2018 Jeep Wrangler comes with a part-time 4WD system. This means you can switch between 2WD (two-wheel drive) and 4WD (four-wheel drive) depending on your needs. The Wrangler uses a transfer case lever to control this. There are several modes:
- 2H (Two-Wheel High): Standard driving mode for dry pavement.
- 4H (Four-Wheel High): Used for slippery surfaces like snow, sand, or mud.
- N (Neutral): For towing.
- 4L (Four-Wheel Low): For extreme conditions like deep mud or steep hills.
Most daily driving should be done in 2H. Switching to 4H or 4L is recommended when you need extra traction.

Step-by-step: How To Put 2018 Jeep Wrangler In 4wd
1. Assess Road Conditions
Before shifting, check the road. Use 4H for light off-roading, snow, sand, or wet roads. Use 4L only when you face steep inclines, deep mud, or heavy rocks.
2. Prepare Your Jeep
For 4H, your Jeep can be moving. For 4L, your Jeep must be stopped or moving very slowly (less than 3 mph).
3. Locate The Transfer Case Lever
You’ll find the lever next to the gear shifter. It’s labeled with 2H, 4H, N, 4L.
4. Shifting From 2h To 4h
- Keep your speed under 55 mph.
- Take your foot off the accelerator.
- Firmly pull the transfer case lever from 2H to 4H.
- You’ll feel the change; a light may show on your dashboard.
5. Shifting From 4h To 4l
- Bring your Jeep to a stop or crawl at less than 3 mph.
- Shift your transmission to Neutral (N).
- Firmly pull the lever from 4H to 4L.
- Wait a few seconds; the 4L indicator will light up.
- Shift your transmission back to Drive or Reverse as needed.
6. Returning To 2h
- To go back to 2H, slow down under 55 mph.
- Take your foot off the gas.
- Move the lever back to 2H.
Practical Tips For Using 4wd
- Only use 4WD on slippery surfaces. Using it on dry pavement can damage the system.
- When switching to 4L, always stop or drive very slowly.
- If you hear grinding or feel resistance, don’t force the lever. Instead, gently reverse, then try again.
Common Mistakes To Avoid
- Engaging 4WD on dry pavement: This puts stress on the drivetrain.
- Switching to 4L at high speed: Can damage the transfer case.
- Forgetting to shift transmission to Neutral: The transfer case won’t engage properly.
- Ignoring dashboard lights: Warning lights mean something isn’t right.
