📚 Vehicle History

Jeep Brand Legacy:

Jeep has a storied history in off-road vehicles, originating with military applications in WWII. The Grand Cherokee line, introduced in 1993, aimed to blend SUV utility with luxury and on-road comfort.

Wj Generation Introduction:

The WJ generation of the Grand Cherokee debuted for the 1999 model year, succeeding the ZJ. The product information listing '1994' for a 'WJ' model is inconsistent with industry-standard model year designations, as the WJ platform began in 1999. It is highly probable that '1994' is an error in the product listing, and the manual pertains to the *ZJ* generation of the Grand Cherokee, which ran from 1993 to 1998. For the purpose of this analysis, we will address the likely correct ZJ generation if the year is indeed 1994.

Zj Generation Production Years:

1993-1998.

Manufacturing Locations:

Primarily Detroit, Michigan, USA.
