Command-Trac (Part-time 4WD):
This system is for off-road use only and should *not* be used on dry pavement. Using it on dry pavement can damage the drivetrain.
1. Shift into Neutral (N): Bring your vehicle to a complete stop. Shift the automatic transmission into Neutral (N) or depress the clutch fully if you have a manual transmission. This is crucial to avoid drivetrain damage.
2. Engage 4WD: There's a rotary dial or lever (usually located on the floor console or near the shifter) marked with 2H (2-wheel high), 4H (4-wheel high), and 4L (4-wheel low). Rotate/move the lever to 4H for high-range 4WD.
3. Drive: Slowly accelerate.
4. Engage 4L (4-wheel low): For extremely low traction situations like mud or steep inclines, you can engage 4L (4-wheel low) in the same manner as 4H. This significantly reduces speed but increases torque. Remember to engage 4L only at low speeds or while stopped.
Selec-Trac (Full-time 4WD):
This system can be used on dry pavement, offering a blend of 2WD and 4WD capabilities. It's more convenient for daily driving but still offers off-road capability.
1. Select the desired mode: The Selec-Trac system typically uses a rotary dial with positions like 2WD (high), 4WD (Full-Time Auto), and 4WD Low (4L).
2. Engage 4WD Full-Time Auto: Rotate the dial to the "4WD Full-Time Auto" or a similar designation. This automatically distributes power between the axles based on driving conditions.
3. Engage 4L (4-wheel low): For low-traction situations, select the 4L mode. Remember to only engage 4L at low speeds or when stopped.
Important Considerations for Both Systems:
* Speed: Never engage or disengage 4WD while moving at high speeds. Always come to a complete stop.
* Surface: Avoid using 4H on dry pavement with Command-Trac. It can cause binding and damage.
* Terrain: Choose the appropriate setting (4H or 4L) based on the terrain.
* Owner's Manual: Refer to your vehicle's owner's manual for specific instructions and safety precautions. It will definitively tell you which system you have and detail the proper procedure. This information is crucial for safe and proper operation.
If you're unsure about which system you have or how to operate it, consulting your owner's manual or a qualified mechanic is recommended. Incorrect 4WD usage can damage your vehicle's drivetrain.
