Cherokee Xj Introduction:
The XJ Cherokee, introduced in 1984, was revolutionary as the first compact SUV with a unibody construction, offering a lighter and more fuel-efficient alternative to body-on-frame SUVs.
Cherokee Yj Introduction:
The YJ Wrangler (introduced in 1987) replaced the CJ-7 and featured rectangular headlights, a departure from previous Jeep designs. The 1984 mention in the manual title might refer to early development or shared components, though YJ officially began with the 1987 model year. This manual likely focuses on the XJ, with potential YJ overlap for certain systems.
