Original 2003 Jeep Grand Cherokee Dealer Service Manual Supplement . This Service Manual Supplement is what the Dealerships used to service your Jeep Grand Cherokee. It contains diagrams, illustrations, information, specifications and procedures to repair and maintain your Jeep. This Manual was meant to be used in conjunction with the Factory 2002 Jeep Grand Cherokee Service Manual. The 2003 Supplement contains any updates, changes or additions to the 2002 Manual. Very informative and useful for the Jeep owner. Very hard to find since these were a Dealer only item that were not available to the public. It is in good condition with minor wear and blemishing from use in a Dealership.
