Owning a Jeep Grand Cherokee means you’re ready for adventure, but switching to 4 wheel drive isn’t always obvious. Many drivers are unsure how to activate the system, especially if they’re new to SUVs. Let’s make it clear: using 4WD correctly keeps you safer and helps your Jeep perform its best on rough roads. This guide covers all four main ways to put your Grand Cherokee in 4 wheel drive, with practical advice and tips many beginners miss. Whether you’re heading into snow, mud, or just want to understand your vehicle better, you’ll find the answers here.
Understanding 4 Wheel Drive In Jeep Grand Cherokee
Before learning the steps, it’s helpful to know why 4WD matters. The Jeep Grand Cherokee offers several types of 4WD systems, including Quadra-Trac I, Quadra-Trac II, Quadra-Drive II, and Selec-Terrain. These systems help the vehicle distribute power to all four wheels, improving traction on slippery or uneven surfaces. According to Jeep, about 70% of Grand Cherokees sold in the US have some form of 4WD, showing how common and valuable this feature is.
Most Grand Cherokees are built for everyday driving, but when you need extra grip—like on a snowy hill or muddy path—activating 4WD changes how your vehicle handles. Not all 4WD systems work the same, so knowing your Jeep’s setup is key.
1. Using The 4wd Auto Mode
Many modern Jeep Grand Cherokees include a 4WD Auto mode. This is the simplest way to activate four-wheel drive, and it works without much driver input.
- Start your Jeep and make sure it’s in Park.
- Locate the 4WD Auto button or dial near the gear shifter.
- Press or turn to 4WD Auto. The system will automatically engage 4WD when needed.
This mode is perfect for daily driving because it senses when wheels slip and transfers power to all four wheels. You don’t need to monitor the road constantly—the system does the work for you.
Non-obvious insight: If you switch to 4WD Auto during bad weather, the system won’t stay in 4WD all the time—it activates only when needed. This prevents extra wear on your drivetrain and saves fuel.
2. Manually Selecting 4wd Low
For tougher conditions, like deep snow or rocks, 4WD Low gives more torque and control. This mode is not for regular roads, but is critical in severe off-road situations.
- Stop your Jeep completely and shift into Neutral.
- Locate the 4WD Low switch or dial.
- Turn or press to engage 4WD Low. Wait for the indicator on the dashboard to confirm activation.
- Shift back to Drive and proceed slowly.
Tip: Only use 4WD Low at speeds below 25 mph. Driving fast in this mode can damage your Jeep.
Non-obvious insight: Many drivers forget to shift to Neutral before activating 4WD Low. The system won’t engage unless you do, so double-check this step.
3. Using Selec-terrain System
Newer Grand Cherokees offer the Selec-Terrain system, which lets you pick a drive mode for different surfaces.
- Find the Selec-Terrain knob near the gear shifter.
- Choose a mode: Snow, Mud, Sand, Rock, or Auto.
- The vehicle adjusts the throttle, brakes, and 4WD settings for optimal performance.
For example, if you’re driving in snow, turn the knob to Snow. The Jeep will send more power to the wheels that need it most, changing how the transmission and traction control work.
Here’s a quick comparison of the Selec-Terrain modes:
| Mode | Recommended Surface | Key Feature |
|---|---|---|
| Auto | Normal roads | Automatic adjustment |
| Snow | Snow, ice | Enhanced traction |
| Mud | Mud, wet grass | Wheel spin control |
| Sand | Loose sand | High wheel spin |
| Rock | Rocky terrain | Low-speed torque |
Tip: Always select the mode that matches your environment. Using the wrong mode can reduce traction.
4. Engaging 4wd With Quadra-trac And Quadra-drive
Some Grand Cherokees are equipped with Quadra-Trac II or Quadra-Drive II. These systems use sensors and clutches to control power distribution. While they are mostly automatic, you can still influence their behavior.
- Make sure your Jeep is in Auto mode.
- If you need more traction, switch to 4WD Low using the steps explained earlier.
- For extra grip, use the Selec-Terrain system alongside Quadra-Trac or Quadra-Drive.
These systems are advanced—they react quickly to changing road conditions. For example, if one wheel slips, Quadra-Drive can transfer up to 100% of torque to the wheel with grip.
Here’s a brief comparison of Jeep 4WD systems:
| 4WD System | Activation | Main Benefit |
|---|---|---|
| Quadra-Trac I | Automatic | Simple, hands-off |
| Quadra-Trac II | Manual & automatic | More control |
| Quadra-Drive II | Automatic | Advanced torque transfer |
| Selec-Terrain | Manual | Custom settings |
Non-obvious insight: Even with automatic systems, you should regularly check your tires. Uneven tire wear can confuse 4WD sensors and reduce performance.
Common Mistakes To Avoid
Switching to 4WD isn’t difficult, but mistakes can lead to costly repairs or less safety.
- Activating 4WD Low while moving: Always stop first.
- Using 4WD on dry pavement: This causes extra strain and can damage the system.
- Forgetting tire checks: Proper tire pressure and tread are vital for 4WD to work well.
Practical Tips For 4wd Use
- Practice switching modes in a safe area, like an empty parking lot.
- Consult your owner’s manual for specific instructions—Jeep models can differ.
- If unsure, use 4WD Auto for most situations; save 4WD Low for real off-road driving.
Real-world Example
In a 2021 survey, over 60% of Jeep Grand Cherokee owners said they used 4WD in snow at least once a year. Many felt safer and had fewer incidents compared to 2WD drivers. Learning to use 4WD confidently can make a big difference when weather gets rough.

Frequently Asked Questions
How Do I Know If My Jeep Grand Cherokee Has 4wd?
Most Grand Cherokees have 4WD badges on the rear or sides. You can also check your owner’s manual or the dashboard for 4WD controls.
Can I Switch To 4wd While Driving?
You can switch to 4WD Auto while driving, but for 4WD Low, always stop and shift to Neutral first.
Is 4wd Better Than Awd?
4WD is designed for tough conditions and off-road use. AWD is better for normal roads and light snow. Grand Cherokees offer both, depending on the model.
How Does 4wd Affect Fuel Economy?
Using 4WD can lower fuel economy by 5–10%. Use it only when needed to save gas.
What’s The Best Mode For Driving In Heavy Rain?
4WD Auto or Selec-Terrain Snow/Mud modes work best for wet roads. They help prevent slipping and improve control.
Learning how to use your Jeep Grand Cherokee’s 4 wheel drive is simple once you know where to look and what to do. Practice the steps, avoid common mistakes, and trust your Jeep to handle whatever the road throws at you.
