To turn off the 4-wheel drive on a 2002 Toyota 4Runner, the method depends on whether your vehicle has the Multi-Mode 4WD system (button-operated) or the Part-Time 4WD system (lever-operated). For the common Multi-Mode system, it's as simple as pressing a button.
Identifying Your 4WD System
Before disengaging, it's helpful to know which 4WD system your 2002 4Runner is equipped with:
- Multi-Mode 4WD (Common on Limited models, optional on SR5): This system features a button, usually located on the dashboard or near the gear shifter, often labeled "4WD" or with a visual representation of a transfer case. It allows for driving in 2WD, 4WD High (full-time, can be used on pavement), and 4WD High with the center differential locked, as well as 4WD Low with the center differential locked.
- Part-Time 4WD (Standard on SR5 and Sport Edition): This system uses a dedicated transfer case shifter lever located next to your main gear shifter. It typically has positions for 2H, 4H, and 4L. This system should not be used on dry, paved roads in 4WD.
Turning Off 4WD for Multi-Mode Systems (Button-Operated)
If your 2002 4Runner has the Multi-Mode 4WD system, which includes a button for engaging and disengaging four-wheel drive, the process is quite simple.
Step-by-Step Instructions
- Locate the 4WD Button: Find the button on your dashboard or center console. It's often marked with "4WD" or an icon depicting a vehicle with all four wheels engaged.
- Press the Button: To turn off the 4-wheel drive and return to two-wheel drive (2WD), simply press the 4WD button.
- Confirm Disengagement:
- You should see the 4WD indicator light on your instrument panel turn off.
- It may take a few moments and possibly require driving a short distance in a straight line or backing up slightly for the system to fully disengage.
- The button also often controls the center differential lock within the 4WD system, allowing you to cycle between 2WD, 4WD High (unlocked center differential), and 4WD High (locked center differential). Pressing it until the 4WD indicator is off ensures you are in 2WD.
When to Disengage
While Multi-Mode 4WD allows for full-time 4WD on all surfaces (when the center differential is unlocked), switching back to 2WD on dry, paved roads is recommended. This improves fuel efficiency, reduces wear on drivetrain components, and provides a smoother driving experience.
Turning Off 4WD for Part-Time Systems (Lever-Operated)
If your 2002 4Runner has the Part-Time 4WD system with a transfer case lever, follow these steps to disengage.
Step-by-Step Instructions
- Shift from 4H to 2H:
- Slow down to below 50 mph (or as recommended in your owner's manual).
- Lift your foot off the accelerator.
- Shift the transfer case lever from 4H (4-High) to 2H (2-High).
- Drive in a straight line for a short distance or make a gentle turn to allow the hubs to disengage fully.
- The 4WD indicator light on your dashboard should turn off.
- Shift from 4L to 2H (if in 4L):
- Bring the vehicle to a complete stop.
- Shift your main transmission into Neutral (N).
- Shift the transfer case lever from 4L (4-Low) through 4H to 2H.
- Shift your main transmission back into Drive (D) or Reverse (R).
- The 4WD indicator light should turn off.
Important Note
Part-Time 4WD is designed for off-road use, slippery surfaces, or low-traction conditions. It should not be used on dry, paved roads, as it can cause drivetrain binding and damage.
General Tips for 4WD Disengagement
- Indicator Lights: Always pay attention to the 4WD indicator light on your dashboard. It confirms the system's status. If it blinks or remains on after attempting to disengage, consult your owner's manual.
- Drive Straight: Sometimes, the drivetrain needs to release tension. Driving a short distance straight, or even gently weaving, can help the system disengage.
- Smooth Operation: Avoid abrupt maneuvers when shifting in or out of 4WD.
- Consult Your Owner's Manual: For detailed, model-specific instructions and any unique considerations for your vehicle, always refer to your 2002 Toyota 4Runner Owner's Manual.
