The label also lists the: • gross vehicle weight rating (GVWR) and the gross front and rear axle weight ratings (GAWR’s) based on a minimum tire rim size and a maximum cold tire inflation pressure; • month and year of vehicle manufacture; • vehicle identification number (VIN); • type of vehicle and • month, day and hour (MDH) of final assembly. The label is located on the driver’s side door edge.

VEHICLE CODE PLATE A metal vehicle code plate is attached to the left (driver) side of the dash panel in the engine compart- ment (Fig. 5). There can be a maximum of seven rows of vehicle information imprinted on the plate. The information should be read from left to right, starting with line 1 at the bottom of the plate up through line 7 (as applicable) at the top of the code plate. Refer to the decoding chart to decode lines 1 up through 3. Lines 4 through 7 (if used) on the vehicle code plate are imprinted on the plate (in sequence) accord- ing to the following: • 3-character sales code, • 3-digit numerical code, and • 6-digit SEC code.

If there is not enough space left in the row for all of the 6-digit SEC code (if used): • the unused space will remain blank, and • the code will be listed in the next row. The last nine positions of row 7 will contain a 2-digit code, when applicable, and a 6-digit gateline serial number (same as the last 6 numbers of the VIN). The last code imprinted on a vehicle code plate will be followed by the imprinted word END. When two vehicle code plates are required, the last available spaces on the first plate will be imprinted with the letters CTD (for continued). When a second vehicle code plate is necessary, the first four spaces on each row will not be used because of the plate overlap. ENGINE AND TRANSMISSION/TRANSFER CASE IDENTIFICATION When required, refer to Group 9—Engines for all engine identification data. Refer to Group 21—Trans- missions for all transmission/transfer case identification data. MAJOR COMPONENT IDENTIFICATION When required, refer to the applicable service information group for major component identification data. TIRE INFLATION PRESSURE LABEL The tire inflation pressures label is located on the glove box door inside panel (Fig. 6). The tires should also be inspected for visible wear. Also, inspect the tires for cracks, bulges and other road hazard dam- age. Refer to Group 22—Tires And Wheels. VEHICLE DIMENSION DATA The vehicle dimension data charts list the exterior and interior dimensions for each type of Jeept vehicle. VEHICLE LOAD DATA The Vehicle Load Data chart lists the following information: • the gross vehicle weight rating (GVWR), • the gross axle weight ratings (GAWR), • the cargo weight, and • the passenger weight for each Jeept type/body style. INTERNATIONAL VEHICLE CONTROL AND DISPLAY SYMBOLS Most of the graphic symbols illustrated in the following chart are used to identify various instrument controls and displays.
