Therefore, there's no "unlocking" 4WD. Instead, you select between different drive modes:
* 2WD (or 2H): This mode sends power primarily to the rear wheels. Some 88 Subarus may not have a true 2WD option, relying on the viscous coupling to handle most normal driving situations.
* 4WD (or 4H): This mode engages the center differential, allowing power to be distributed to all four wheels. This is the typical setting for most driving conditions requiring more traction.
* 4WD Low (or 4L): This engages a low-range gear ratio for very low-speed, high-traction situations such as extreme off-roading. It is generally not advisable for normal road driving.
How to select the drive mode:
The specific method depends on your exact Subaru model (e.g., Loyale, GL, XT). Look for a lever or switch typically located on the floor or console, often near the gear shifter. This lever will have positions for 2WD, 4WD, and 4WD Low (if equipped). The markings might be different (e.g., 2H, 4H, 4L), but the concept is the same.
Important Considerations:
* Don't switch into 4WD or 4WD Low on dry pavement at high speeds. Doing so can cause damage to the drivetrain. Only engage 4WD when needed and at low speeds.
* Consult your owner's manual. The specifics of your 4WD system are detailed in there. This information is crucial for safe and proper operation.
If you can't find the lever or switch, or if it's not functioning correctly, you'll need to consult a repair manual or a Subaru mechanic. There might be a mechanical issue with the system.
