Getting your 2017 Jeep into 4 wheel drive can make a big difference in rough weather or off-road conditions. Many Jeep owners are not sure how to do this the right way.
If you are new to Jeeps or just want to make sure you are using 4 wheel drive correctly, you are in the right place.
This guide will help you understand the different 4WD systems in the 2017 Jeep lineup, show you the steps to engage 4WD, and give you tips to avoid common mistakes.
Understanding 4 Wheel Drive In A 2017 Jeep
The 2017 Jeep models come with different 4 wheel drive systems. The most common are Command-Trac, Selec-Trac, and Rock-Trac. Knowing which one you have is important because the steps can be a bit different.
Types Of 4wd Systems
- Command-Trac: Found in most Wrangler Sports and Saharas. This is a part-time system best for off-road or slippery roads.
- Selec-Trac: More automatic. Found in some Grand Cherokees and Libertys. It can switch between 2WD and 4WD as needed.
- Rock-Trac: Used in Wrangler Rubicon for serious off-roading. Offers extra low gearing.
You can check your owner’s manual or look for labels near the shifter to see which system your Jeep has.
Basic Steps To Put Your 2017 Jeep In 4 Wheel Drive
Most 2017 Jeeps have a lever or knob near the gear shifter for 4WD. Here is how to use them safely:
- Slow Down: Always slow to 2-5 mph or stop before switching to 4WD.
- Shift to Neutral: For some systems, you need the transmission in Neutral.
- Engage the 4WD Lever or Switch:
- For a lever, pull or push it to the right setting (4H or 4L).
- For a dial, simply turn to the desired mode.
- Wait for Engagement: You may hear a click or see a light on the dash.
- Return to Drive: Move the transmission back to Drive (D) and continue.
Example: 2017 Jeep Wrangler (command-trac)
- For 4H (4 High): Slow below 45 mph. Keep your Jeep in Drive. Pull the lever from 2H to 4H. You can do this while moving slowly.
- For 4L (4 Low): Stop completely. Shift to Neutral. Move the lever to 4L. Wait for the 4WD light on the dash.
Example: 2017 Jeep Grand Cherokee (selec-trac)
- For 4 Auto: Just turn the knob to “Auto.” The system handles the rest.
- For 4 Low: Stop the vehicle. Shift to Neutral. Push and turn the knob to “4 Low.” Wait for dash confirmation.
When To Use 4 Wheel Drive
Using 4WD at the right time keeps your Jeep running smoothly.
- 4H (4 High): Snow, sand, loose gravel, or mild off-roading. This mode gives good traction without changing speed.
- 4L (4 Low): Deep mud, steep hills, rocky trails, or when you need max power and control at low speeds.
Never use 4L on dry pavement—it can damage the drivetrain.
Comparison Of 4wd Modes
Here’s a quick look at how the different modes compare:
| Mode | Best For | Max Speed | How to Engage |
|---|---|---|---|
| 2H | Normal roads | Full speed | Standard driving |
| 4H | Snow, dirt, rain | Up to 55 mph | Shift on the fly |
| 4L | Mud, rocks, steep hills | Below 25 mph | Stop & shift to Neutral first |
Practical Tips And Common Mistakes
Switching to 4WD is simple, but here are a few key tips:
- If you hear grinding, stop and try again—never force the lever.
- Only use 4WD on loose or slippery surfaces.
- After using 4L, shift back to 2H or 4H before returning to pavement.
- Check tire pressure before off-roading, as uneven tires can affect 4WD.
A common mistake is leaving your Jeep in 4H or 4L on dry pavement. This can wear out parts quickly.
Another is trying to shift to 4L while moving always stop first.

Advanced: Getting Unstuck
Sometimes, even with 4WD, your Jeep may get stuck. Here’s what to do:
- Shift to 4L for maximum torque.
- Turn the wheel left and right to find traction.
- Rock the vehicle gently, moving forward and backward.
- If you have locking differentials, engage them.
- Use sand or traction mats under the tires.
Never spin your wheels too fast—it can dig you in deeper.
Quick Troubleshooting
If your 4WD is not engaging:
- Check if you are fully stopped for 4L.
- Make sure you are in Neutral when required.
- Look for warning lights on your dash.
- If the 4WD light blinks or stays off, consult your manual or a mechanic.
Sometimes, low transmission fluid or a damaged switch can cause problems. Regular maintenance helps prevent these issues.
