1. Vehicle Speed: Bring the vehicle to a complete stop. 4-Low should *never* be engaged while the vehicle is moving.
2. Transfer Case Shifter: The transfer case shifter is usually located on the floor console, near the gear shift. It will have positions like 2H (2-wheel High), 4H (4-wheel High), and 4L (4-wheel Low).
3. Engage 4-Low (4L): Shift the transfer case lever to the 4L position. You may need to overcome some resistance; this is normal.
Important Considerations:
* Terrain: Only use 4-Low on low-traction surfaces like snow, ice, mud, or sand. Using 4-Low on dry pavement can damage the drivetrain.
* Speed: 4-Low is for very low speeds, typically below 20 mph (and often much slower). Driving faster in 4-Low can cause damage.
* Steering: 4-Low significantly increases the steering effort. Be prepared for this.
* Tire Pressure: Ensure your tires are properly inflated for the terrain.
If you're unsure how to operate the 4WD system in your specific Commander, consult your owner's manual. It will have diagrams and detailed instructions specific to your vehicle's model and options.
