Understanding Jeep Grand Cherokee 4 Wheel Drive Systems
Not every Jeep Grand Cherokee has the same 4WD system. The model year and trim decide which system you have. Knowing your system is key to using 4WD correctly.
Main Types Of 4 Wheel Drive Systems
Jeep Grand Cherokee usually offers these four 4WD systems:
- Quadra-Trac I
- Quadra-Trac II
- Quadra-Drive II
- Quadra-Trac SRT/Active Drive
Each system works differently and has its own method for engaging 4WD. Let’s look at each one in detail.
How To Turn On 4 Wheel Drive: Quadra-trac I
Quadra-Trac I is the simplest system. It is a full-time 4WD system, which means all four wheels are always powered. There’s no button, lever, or switch to turn on 4WD—it’s always active.
How It Works
- Power goes to all wheels automatically.
- The system adjusts power between the front and rear as needed.
- No driver action is needed.
When To Use
You don’t have to do anything. Just drive as usual. The system will handle wet, snowy, or muddy roads without your help.
Pros And Cons
Pros:
- No thinking required: Great for beginners.
- Always ready: Instant grip when roads get slippery.
Cons:
- Less control: You can’t choose between 2WD and 4WD.
- Slightly less fuel-efficient than 2WD systems.
Example
You’re driving on a snowy road. Quadra-Trac I automatically gives power to all wheels, so you stay in control.
How To Turn On 4 Wheel Drive: Quadra-trac Ii
Quadra-Trac II is a full-time 4WD system with extra features. It has a 2-speed transfer case and a “4WD Low” mode for tough terrain.
How To Engage 4wd
- Normal driving: 4WD is always on; you don’t need to turn it on.
- For tough terrain: Use the “4WD Low” mode.
Steps To Activate 4wd Low
- Stop the vehicle and shift into Neutral (N).
- Find the 4WD control dial or lever (usually in the center console).
- Turn or pull the control to “4WD LOW.”
- Wait for the indicator light to confirm it’s engaged.
- Shift back into Drive (D) and move slowly.
Important: Only use 4WD Low at speeds below 25 mph (40 km/h). It’s for deep snow, mud, or steep hills.
When To Use
- 4WD Auto/High: For daily driving and most weather.
- 4WD Low: When you need more power at low speeds, like off-road or climbing.
Pros And Cons
Pros:
- More control: Choose between normal and low-range 4WD.
- Versatile: Good for city and off-road.
Cons:
- Slight learning curve: Must stop and shift to Neutral for 4WD Low.
- Not for high-speed driving in 4WD Low.
Example
You’re stuck in deep mud. Shift to Neutral, engage 4WD Low, and drive out slowly with extra power.
How To Turn On 4 Wheel Drive: Quadra-drive Ii
Quadra-Drive II is a top-level 4WD system found in luxury and off-road Grand Cherokee models. It offers automatic power delivery and can send almost all engine power to a single wheel if needed.
How To Engage 4wd
- Full-time 4WD: No need to turn it on; it’s always active.
- 4WD Low: For maximum traction, shift to Low.
Steps To Use 4wd Low
- Stop the vehicle and set the transmission to Neutral.
- Move the transfer case lever or dial to “4WD LOW.”
- Wait for the dash light to confirm.
- Shift back to Drive.
Unique Features
- Electronic limited-slip differentials: Help you in tough spots by sending power to the wheels with grip.
- Selec-Terrain system: Choose modes like Snow, Sand, Mud, Rock for better performance.
Pros And Cons
Pros:
- Maximum traction: Best for challenging trails.
- Automatic adjustments: Handles difficult situations for you.
Cons:
- More expensive to repair if something breaks.
- Heavier: Slightly less fuel-efficient.
Example
On a rocky hill, Quadra-Drive II senses which wheels slip and sends power to the wheels that grip, helping you climb safely.
How To Turn On 4 Wheel Drive: Quadra-trac Srt/active Drive
This system is mostly found in high-performance Grand Cherokee SRT or Trackhawk models. It’s designed for speed and traction rather than off-road use.
How It Works
- All-wheel drive (AWD): Power automatically goes to all four wheels.
- No manual controls: You cannot switch between 2WD and 4WD.
How To Use
- Just drive as usual. The system automatically manages power for the best grip.
Special Features
- Performance-tuned: Designed for fast acceleration and cornering.

Pros And Cons
Pros:
- Great for high speeds and wet roads.
- No driver action needed.
Cons:
- Not meant for rough off-roading.

Example
You’re driving fast on a rainy highway. The system instantly sends power where it’s needed for safe, confident driving.

Cost Of 4 Wheel Drive System Maintenance
Owning a 4WD Jeep means you’ll have extra parts to maintain. Here’s a rough cost overview:
| Maintenance Item | Estimated Cost (USD) | How Often |
|---|---|---|
| Transfer Case Fluid Change | $120–$250 | Every 30,000 miles |
| Differential Fluid Change | $100–$200 | Every 30,000–60,000 miles |
| 4WD System Inspection | $80–$150 | Annually |
Non-obvious tip: If you hear clicking or grinding when using 4WD, get it checked immediately. Small problems can become big repairs.
When Should You Use 4 Wheel Drive?
4WD helps most when:
- Roads are icy, snowy, or muddy
- You’re going off-road or on steep hills
- You need to pull a heavy load in poor conditions
But 4WD won’t help you stop faster. Always drive carefully, even with 4WD on.
Non-obvious tip: Many drivers forget that 4WD systems don’t help much on dry roads and can even make turning harder. Use 4WD only when needed for best results.
Is 4 Wheel Drive Worth It?
For most Jeep Grand Cherokee drivers, 4WD is a big advantage in winter and off-road conditions. However, it comes with higher costs:
- Upfront price: Grand Cherokee 4WD models cost $2,000–$3,500 more than 2WD.
- Fuel economy: 4WD models use more gas—about 1–2 mpg less.
- Maintenance: More moving parts mean higher repair bills if something breaks.
If you mostly drive on dry, flat roads, 4WD may not be worth the extra cost. But if you face snow, mud, or enjoy adventures, it’s a smart choice.
