If you drive a Jeep Grand Cherokee Laredo, you probably know about its strong 4×4 system. But many owners aren’t sure how to activate 4×4 easily, especially if they’re new to off-roading or winter driving.
Getting it right can make a big difference in safety and performance. This guide explains the steps, types of 4×4 systems in the Laredo, and real-world advice so you use 4×4 with confidence—without stress or confusion.
Understanding 4×4 In The Jeep Grand Cherokee Laredo
The Grand Cherokee Laredo comes with different 4×4 systems. Knowing which one is in your vehicle is the first step. Most Laredos have one of these four:
- Quadra-Trac I
- Quadra-Trac II
- Quadra-Drive II
- Selec-Terrain System
Each system has unique features and activation methods. Check your owner’s manual or the badge on your shifter or dash to confirm which system you have.
Quick Comparison Of 4×4 Systems
Here’s a table to help you see the differences:
| System | Activation Method | Best For | Driver Control |
|---|---|---|---|
| Quadra-Trac I | Automatic | Everyday driving | No input needed |
| Quadra-Trac II | Manual/Automatic | Off-road, snow | Driver selects 4LO |
| Quadra-Drive II | Automatic | Severe conditions | Minimal input |
| Selec-Terrain | Dial selector | Custom terrain | Driver selects mode |
Many owners miss that some systems are always on, while others need you to act. Let’s look at each system in detail.
1. Quadra-trac I: Fully Automatic
Quadra-Trac I is the simplest 4×4 system. You don’t need to do anything special to turn it on. The vehicle’s computer controls the system, sending power to all four wheels automatically.
- No levers or switches to activate.
- Works best for daily driving and light off-road use.
- If you lose traction, the system sends power where needed.
Pro Tip: If your Laredo has Quadra-Trac I, you’re always in 4×4. There’s no separate “activation” step. Many new owners don’t realize this and look for a button or lever that doesn’t exist.
2. Quadra-trac Ii: Manual And Automatic Features
Quadra-Trac II offers more control. It has a two-speed transfer case with 4HI (high range) and 4LO (low range).
To activate 4×4 Low (4LO):
- Stop the vehicle and shift into neutral (N).
- Firmly press the brake pedal.
- Move the transfer case lever or knob (usually near the gear shifter) from 4HI to 4LO.
- Wait for the 4LO indicator light on the dash.
When to use 4LO: Tough off-road, steep hills, deep snow, or sand. Never use 4LO on dry pavement—it can damage the system.
Common Mistake: Many drivers try to shift into 4LO while moving or not in neutral. Always stop fully and shift to neutral first. For everyday driving, leave it in 4HI (which is often selected automatically).
3. Quadra-drive Ii: Advanced Automatic
Quadra-Drive II is Jeep’s most advanced system. It includes electronic limited-slip differentials and senses wheel spin quickly.
- No manual activation for standard 4×4.
- System automatically shifts power between wheels for maximum grip.
- For 4LO, follow the same steps as Quadra-Trac II: Stop, shift to neutral, then select 4LO.
Insider Tip: While you can let Quadra-Drive II handle most conditions, learning to use 4LO properly helps in tough off-road spots. Some drivers forget to switch back to 4HI after leaving rough terrain, which can cause extra wear.
4. Selec-terrain System: Choose Your Mode
Selec-Terrain adds a dial on the center console. It lets you pick the best traction setting for your current road or trail.
The main modes are:
- Auto: For regular driving.
- Snow: For slippery, icy roads.
- Sand/Mud: For loose or muddy surfaces.
- Rock: For crawling over rocks (requires 4LO).
- Sport: For faster response on pavement.
How to activate:
- Turn the dial to your desired mode (can do while driving at low speeds).
- For Rock mode, stop, shift to neutral, and select 4LO first.
Practical Example: If you’re facing a snowstorm, simply turn the dial to “Snow” before you start driving. The vehicle adjusts throttle, transmission, and traction automatically.
Selec-terrain Modes At A Glance
| Mode | Use Case | Special Features |
|---|---|---|
| Auto | Normal roads | Automatic adjustment |
| Snow | Icy, snowy roads | Gentler throttle, more traction |
| Sand/Mud | Beaches, mud | Higher wheel spin allowed |
| Rock | Rocks, steep terrain | Uses 4LO, max grip |
| Sport | Performance | Sharper throttle, firmer shifts |
Extra Tips For Easy 4×4 Activation
- Know your system: Always check your manual for your exact model year.
- Practice in a safe place: Try activating 4LO or Selec-Terrain modes in a parking lot before your first real need.
- Warning lights: If any 4×4 warning lights stay on, have your system checked.
- Maintenance matters: Regularly check transfer case fluid and tire pressure for best performance.
Many drivers forget to align tire sizes or ignore warning lights. Both can cause problems with 4×4 engagement.
Real-world Example
During a blizzard in Colorado, a Laredo owner used Selec-Terrain’s Snow mode and 4LO to climb a steep, icy driveway. While neighbors’ cars slipped, the Jeep handled it without trouble.
This shows how using the right mode makes a big difference.
Frequently Asked Questions
How Do I Know Which 4×4 System My Laredo Has?
Check your owner’s manual, look for badges on the gear shifter, or contact your local Jeep dealer with your VIN. Each system has different controls.
Can I Switch Between 4×4 Modes While Driving?
You can change Selec-Terrain modes (except Rock) at low speeds. For 4LO, always stop and shift to neutral before switching.
Does Using 4×4 Lower Gas Mileage?
Yes, running in 4×4 especially 4LO uses more fuel. Use it only when needed for tough conditions.
