The 4-wheel drive (4WD) light on a Toyota RAV4 indicates that the vehicle is in 4WD mode, which enhances traction on slippery or uneven surfaces. If the light remains illuminated while the vehicle is not in 4WD, it may signal a malfunction in the system, such as an issue with the transfer case or drivetrain. It's advisable to consult the owner's manual or a mechanic if the light behaves unexpectedly. Regular maintenance can help ensure the 4WD system functions properly.
