The Jeep Compass 4WD System: A Closer Look
The Jeep Compass is renowned for its off-road prowess, a trait it inherits from its storied lineage. At the heart of this capability is its advanced Jeep Compass 4WD system. Unlike traditional, manually engaged 4WD systems found in older vehicles or more rugged off-roaders, many Jeep Compass models utilize a sophisticated Active Drive 4×4 system. This system is designed to be largely automatic, seamlessly transferring power to the rear wheels only when traction is needed. This means that in most everyday driving situations, your Compass operates as a front-wheel-drive vehicle to maximize fuel efficiency. However, when the system detects slippage or when you select a specific mode, it can instantly engage the rear axle to provide true four-wheel drive.
How Jeep Compass 4×4 Operation Works
The magic behind the Jeep Compass 4×4 operation lies in its intelligent electronic control module. This module constantly monitors various sensors throughout the vehicle, including wheel speed sensors, throttle position, and steering angle. If these sensors indicate that the front wheels are losing traction, the system will automatically engage the rear axle. This is achieved through a power transfer unit (PTU) that sends power to the rear differential. The engagement is so quick and smooth that most drivers might not even notice it happening. This automatic engagement is a significant advantage, as it allows you to focus on driving without constantly worrying about manually switching between 2WD and 4WD.
Exploring Jeep Compass Terrain Modes
For those equipped with the Jeep Selec-Terrain® Traction Management System, activating four-wheel drive and optimizing performance for different conditions becomes even more intuitive. This system allows drivers to select specific modes that tailor the vehicle’s throttle response, transmission shift points, and importantly, the 4WD system’s behavior to suit the environment. The typical Jeep Compass terrain modes include:
- Auto: This is the default setting. The system operates automatically, engaging 4WD only when necessary, balancing performance with fuel efficiency. This is suitable for most everyday driving conditions.
- Snow: Designed for low-traction surfaces like snow and ice. This mode typically softens throttle response and prioritizes a smoother power delivery. The 4WD system may engage more proactively in Snow mode to maintain stability.
- Sand: Optimizes the drivetrain for sandy conditions. This often means more aggressive throttle response and a willingness for the wheels to spin slightly to maintain momentum. The 4WD system will likely remain engaged more consistently.
- Mud: This mode is for deeper, softer surfaces like mud. It typically allows for more wheel slip to help clear mud from the tires and may keep the 4WD system engaged more firmly.
- Rock (if equipped): For models with the more advanced Active Drive II system, the Rock mode engages low-range gearing (4LO) and further refines the 4WD system for crawling over obstacles.
By selecting the appropriate Jeep Compass terrain modes, you can significantly enhance your vehicle’s performance and safety when driving in challenging conditions.
Activating Jeep Compass Four-Wheel Drive: Step-by-Step
As mentioned, many Jeep Compass models operate in an automatic 4WD mode by default. This means you don’t typically need to “put it into 4WD” in the traditional sense. However, if your Compass is equipped with the Selec-Terrain® system, you will use the dial or buttons associated with it to select your desired mode, which in turn influences how the 4WD system operates.
Locating the 4WD Controls
The controls for managing the Jeep Compass 4WD system are typically integrated into the center console.
The Selec-Terrain® Dial/Buttons
On models featuring the Selec-Terrain® system, you’ll find a rotary dial or a set of buttons located near the gear shifter or climate controls. This is your primary interface for selecting Jeep Compass 4WD modes. Simply turn the dial or press the buttons to cycle through the available modes (Auto, Snow, Sand, Mud, and potentially Rock). The selected mode will be indicated on your instrument cluster or the infotainment screen.
Jeep Compass 4WD Lever and Switch Clarification
It’s important to note that most Jeep Compass models, particularly those with the Active Drive I system, do not have a traditional Jeep Compass 4WD lever or a separate Jeep Compass 4WD switch for manually engaging 4WD. The system is designed to be automatic. However, if you have a more advanced system like Active Drive II, you might encounter a Jeep Compass 4LO engagement option. This is typically activated through a button or a combination of button presses on the Selec-Terrain® dial. Engaging 4LO locks the 4WD system and provides lower gearing for extreme off-road situations where maximum torque and control are needed at very low speeds.
Engaging 4LO (If Available)
For models equipped with a low-range gear option (usually denoted as 4LO), Jeep Compass 4LO engagement is a specific process that provides significant benefits for very challenging off-road driving.
Conditions for Engaging 4LO:
- Vehicle Stationary: Always ensure your vehicle is completely stopped before attempting to engage 4LO.
- Transmission in Neutral: Shift the transmission into Neutral (N).
- Brake Applied: Keep your foot firmly on the brake pedal.
Steps for Jeep Compass 4LO Engagement:
- Select 4LO Mode: Locate the button or setting associated with 4LO. This might be on the Selec-Terrain® dial itself, or a separate button nearby.
- Press and Hold: Press and hold the 4LO engagement button. You may need to hold it for a few seconds.
- Confirm Engagement: The instrument cluster will display a notification or icon indicating that 4LO has been successfully engaged. You should also feel a slight change in the vehicle’s feel as the low-range gears are selected.
- Shift into Drive or Reverse: Once 4LO is engaged, you can shift the transmission back into Drive (D) or Reverse (R) to begin moving.
Important Considerations for 4LO:
- Speed Limitations: 4LO is designed for low-speed operation. Avoid exceeding moderate speeds (typically around 20-30 mph, consult your owner’s manual for specific limits) while in 4LO.
- Tire Wear: Prolonged use of 4LO on high-traction surfaces like dry pavement can cause excessive wear on your tires and drivetrain components.
- Disengaging 4LO: To disengage 4LO, follow the same steps in reverse: stop the vehicle, shift to Neutral, press and hold the 4LO disengagement button (or the same button you used to engage it), confirm disengagement on the instrument cluster, and then shift back into Drive or Reverse.
Optimizing Your Jeep Compass 4×4 Engagement
Knowing how to engage the 4WD system is only half the battle. To truly maximize the benefits of your Jeep Compass’s 4WD capabilities, you need to employ smart driving techniques and understand when to use each mode.
When to Use Different Jeep Compass Terrain Modes
The Selec-Terrain® system is your best friend when it comes to optimizing your Jeep Compass 4×4 operation. Here’s a quick guide:

- Drive Smoothly: Avoid sudden acceleration or braking, especially in low-traction conditions, regardless of the mode selected. Smooth inputs help the 4WD system work more effectively.
- Maintain Momentum: In challenging terrain like sand or mud, maintaining a steady, controlled momentum is often more important than raw power.
- Check Your Tires: Proper tire inflation and good tread depth are essential for any 4WD system to function optimally.
- Be Aware of Surroundings: Always assess the terrain and conditions before selecting a mode. Don’t rely solely on the system; your judgment is paramount.
Understanding Your Jeep Compass Drivetrain
The Jeep Compass drivetrain is designed to be adaptable and efficient. It typically consists of a front-wheel-drive biased system that can automatically engage the rear axle. This setup offers a good balance for most drivers, providing the security of 4WD when needed without the constant fuel penalty of a full-time 4WD system.
Jeep Compass 4×4 System Variants
It’s worth noting that Jeep has offered different iterations of its 4WD systems in the Compass over the years.
- Jeep Active Drive I: This is the most common system found on many Compass models. It’s an automatic, single-speed power transfer unit that engages the rear axle when needed. It does not have a 4LO option.
- Jeep Active Drive II: This more advanced system includes a two-speed power transfer unit with a low-range gear option (4LO). This system is typically found on higher trims or specific packages and offers greater off-road capability.
When considering how to put your Jeep Compass in 4WD, identifying which system your vehicle is equipped with is key. If you have a Jeep Compass 4×4 lever or a 4LO button, you likely have Active Drive II. If not, your system is most likely Active Drive I, which operates automatically.
Troubleshooting Common 4WD Issues
While the Jeep Compass 4WD system is generally reliable, like any complex mechanical system, occasional issues can arise.
Warning Lights and Indicators
If a 4WD warning light illuminates on your dashboard, it signifies that the system has detected a fault. Common causes include:
- Sensor Malfunctions: A faulty wheel speed sensor or other sensor can disrupt the 4WD system’s operation.
- Low Fluid Levels: While less common in automatic systems, ensuring proper fluid levels in the PTU and rear differential is important.
- Drivetrain Overheating: In extreme conditions, the 4WD components can overheat, triggering a warning. Allow the vehicle to cool down.
- Tire Size Mismatch: If you have tires of significantly different sizes or wear patterns, it can confuse the 4WD system.
