My new RAV4 is my 6th SUV, and my 3rd with 4WD. But my previous 4WD vehicles all had a manual switch or lever to engage 4WD mode, and I'm a little unclear about how the system works in the RAV4, how the Lock button works, and heck, I'm not even clear on whether it's front-wheel or rear-wheel when in 2WD mode.. Your RAV4 is always 4WD. This button is used to lock front and rear differentials together (center differential lock).. 2002 with 2.4 swap + RAV4.1 manual transmission (4.93 final drive ratio), RAV4.1 LOCKING Center Differential, Torsen type 2 rear differential , Celica GT-Four Stage 1 SPEC clutch kit, 3.5" lift kit: Old Man Emu coil-springs.
