Getting the most from your 2018 Jeep Cherokee means understanding how and when to use its four-wheel drive system. For many drivers, especially those new to SUVs or off-road adventures, switching between two-wheel and four-wheel drive can feel confusing. This guide will make it simple. Whether you face snow, mud, or rough trails, you’ll learn step-by-step how to engage and use 4WD in your 2018 Jeep Cherokee.
Understanding Jeep Cherokee 4wd Systems
The 2018 Jeep Cherokee comes with two main four-wheel drive systems: Jeep Active Drive I and Jeep Active Drive II. Knowing which system your vehicle has is important, as the controls and capabilities differ.
- Jeep Active Drive I is mainly for light off-road and slippery road conditions. It automatically switches power between the front and rear wheels as needed.
- Jeep Active Drive II adds a low range for tougher terrains, making it better for off-roading and deep snow.
To check your system, look in your vehicle manual or ask your dealer. The controls are usually near the gear selector.
Preparing Your Cherokee For 4wd
Before switching to four-wheel drive, take a moment to prepare your vehicle:
- Stop the vehicle or slow down to under 5 mph if you want to shift to low range (Active Drive II).
- Check your surroundings. Make sure the road or terrain is suitable for 4WD.
- Know your mode. For daily driving on dry roads, 2WD is best. Use 4WD only when needed.
A common mistake: Engaging 4WD on dry pavement. This can cause stress on your drivetrain and reduce fuel economy.
How To Engage 4 Wheel Drive In The 2018 Jeep Cherokee
Switching to four-wheel drive is easier than you might think. Here’s how to do it safely:
For Jeep Active Drive I
- Locate the Selec-Terrain knob. It’s usually next to the shifter.
- Choose your setting. Turn the knob to select Auto, Snow, Sport, Sand/Mud. The system adjusts power as needed.
- Drive as usual. The system works automatically; you don’t need to stop or shift gears.
Non-obvious insight: In Auto mode, the system handles traction for you. You might not feel a big difference, but sensors are constantly adjusting to keep you safe.
For Jeep Active Drive Ii
This system includes a 4WD Low mode for extra traction:
- Bring the vehicle to a stop or under 5 mph.
- Shift to Neutral (N) on your transmission.
- Turn the Selec-Terrain knob to your desired setting.
- Press the 4WD LOW button. You’ll see a light on the dashboard when it’s engaged.
- Shift back to Drive (D) and continue.
Important: Always shift to Neutral before selecting 4WD LOW, or the system may not engage.
When To Use Each Mode
Understanding when to use each setting helps protect your Cherokee and keeps you safer.
- Auto: Everyday driving, changing conditions.
- Snow: Icy or snowy roads; reduces wheel spin.
- Sport: For a more responsive drive, not for off-road.
- Sand/Mud: Loose surfaces; helps prevent getting stuck.
- 4WD LOW (Active Drive II): Steep hills, deep mud, or tough off-road.
Never use 4WD LOW on normal roads. It’s only for low-speed, high-traction situations.
Comparison: Active Drive I Vs. Active Drive Ii
Here’s a quick look at the main differences:
| Feature | Active Drive I | Active Drive II |
|---|---|---|
| Low Range Gear | No | Yes |
| Off-road Capability | Basic | Advanced |
| Control | Automatic | Manual (with 4WD LOW) |
If you plan on serious off-roading, Active Drive II is the better choice.
Common Problems And Troubleshooting
Even with an automatic system, issues can arise. Here are some typical problems and solutions:
- Warning lights stay on: Check if you followed the correct steps, especially shifting to Neutral when engaging 4WD LOW.
- Grinding noises: Stop immediately. This could mean the system is not engaging correctly.
- No difference in traction: The system may not engage if on dry pavement. Test in safe, slippery conditions.
If problems continue, consult your mechanic or the official Jeep website. Following the correct procedure is the best way to avoid issues.
Real-world Tips For Using 4wd
- Practice in a safe place. Try switching modes in an empty parking lot before you need it on a snowy road.
- Don’t rely only on 4WD. Good tires and careful driving matter more in slippery conditions.
- Know your limits. Even with 4WD, very deep mud or snow can stop your Cherokee.
- Avoid sharp turns in 4WD LOW. This reduces stress on your drivetrain.
A lot of new users assume 4WD makes them invincible. It helps, but it does not replace common sense and good preparation.
Data: Fuel Economy And 4wd Usage
Using four-wheel drive affects your fuel use. Here’s a quick comparison:
| Mode | Estimated MPG |
|---|---|
| 2WD/Auto | 21 City / 29 Highway |
| 4WD | 19 City / 27 Highway |
| 4WD LOW | Much lower (varies) |
Insight: Use 4WD only when needed to save fuel and reduce wear.
Quick Reference: Steps To Engage 4wd
For those who want a fast checklist:
- Slow down or stop (for 4WD LOW).
- Shift to Neutral (N).
- Select terrain mode.
- Press 4WD LOW (Active Drive II only).
- Shift back to Drive (D).
This process takes less than a minute once you’re familiar with the controls.
Safety Reminders
- Always read your owner’s manual for your exact model.
- Don’t shift to 4WD LOW at high speeds.
- Keep tires properly inflated for best traction.

Frequently Asked Questions
Can I Shift To 4wd While Driving?
Yes, you can switch between Auto, Snow, Sport, and Sand/Mud modes on the go. For 4WD LOW (Active Drive II), stop the vehicle and shift to Neutral first.
Does 4wd Improve Safety In Rain?
It helps with traction, but it doesn’t replace safe driving. Good tires and slower speeds are still most important.
Is It Bad To Leave 4wd On All The Time?
Using Auto mode is fine. Avoid using 4WD LOW or off-road settings on dry roads to prevent damage.
What If My 4wd System Won’t Engage?
Double-check that you followed the steps correctly. If issues continue, visit a Jeep service center.
Will Using 4wd Wear Out My Cherokee Faster?
Occasional use is safe. Regular use on dry pavement can increase wear. Use 4WD only when needed for best results.
