VEHICLE DESIGNATIONS
The Vehicle Designation Codes chart lists the vehi-
cle description(s) and the corresponding vehicle des-
ignation code for each type of Jeeptvehicle (Figs. 1,
2, and 3 ). The vehicle designation codes are different
from the Vehicle Identification Number (VIN) or
body-type/style codes.
VEHICLE SAFETY CERTIFICATION LABEL
A vehicle safety certification label (Fig. 4) is at-
tached to each Jeeptvehiclee. The label also lists
the:
²gross 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;²month and year of vehicle manufacture;
²vehicle identification number (VIN);
²type of vehicle and
²month, day and hour (MDH) of final assembly.
The label is located on the driver's side door edge.
VEHICLE IDENTIFICATION NUMBER (VIN) PLATE
The vehicle identification number (VIN) plate is at-
tached to the top left side of the instrument panel at
the base of the windshield. Each VIN contains 17 al-

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
