The Jimny has a part-time 4WD system controlled by three dashboard buttons: 2WD, 4WD, and 4WD-L. The default is 2WD, powering the rear wheels. When 4WD is pressed, the front wheels are also engaged in high gear. The 4WD-L engages all wheels in a lower gear ratio. Being a part-time 4WD, there is no center differential or viscous coupling to allow for speed differences between the front and rear wheels, so only two-wheel drive mode works well on dry pavement. In Japan, the "Sierra" name was revived in January 2002, when 1.3-litre Jimnys began to be sold as the "Jimny Sierra" rather than as the "Jimny Wide".
