The VIN contains 17 characters that provide data con- cerning the vehicle. Refer to the decoding chart to determine the identification of a vehicle. To protect the consumer from theft and possible fraud the manufacturer is required to include a Check Digit at the ninth position of the Vehicle Identification Num- ber. The check digit is used by the manufacturer and government agencies to verify the authenticity of the vehicle and official documentation. The formula to use the check digit is not released to the general public. WK INTRODUCTION 1

The label is located in the engine compartment on the vehicle hood. Two labels are used for vehicles built for sale in the country of Canada. 2 INTRODUCTION WK

The VECI label(s) contain the following: • Engine family and displacement • Evaporative family • Emission control system schematic • Certification application • Spark plug and gap The label also contains an engine vacuum schematic. There are unique labels for vehicles built for sale in the state of California and the country of Canada. Canadian labels are written in both the English and French languages. These labels are permanently attached and cannot be removed without defacing information and destroying label. VEHICLE CERTIFICATION LABEL DESCRIPTION A vehicle certification label is attached to every DaimlerChrysler Corporation vehicle. The label certifies that the vehicle conforms to all applicable Federal Motor Vehicle Standards. The label also lists: • Month and year of vehicle manufacture. • Gross Vehicle Weight Rating (GVWR). The gross front and rear axle weight ratings (GAWR’s) are based on a minimum rim size and maximum cold tire inflation pressure. • Vehicle Identification Number (VIN). • Type of vehicle. • Type of rear wheels. • Bar code. • Month, Day and Hour (MDH) of final assembly. • Paint and Trim codes. • Country of origin. The label is located on the driver-side door shut-face. WK INTRODUCTION 3

FASTENER IDENTIFICATION DESCRIPTION The SAE bolt strength grades range from grade 2 to grade 8. The higher the grade number, the greater the bolt strength. Identification is determined by the line marks on the top of each bolt head. The actual bolt strength grade corresponds to the number of line marks plus 2. The most commonly used metric bolt strength classes are 9.8 and 10.9. The metric strength class identification number is imprinted on the head of the bolt. The higher the class number, the greater the bolt strength. Some metric nuts are imprinted with a single-digit strength class on the nut face. Refer to the Fastener Identification and Fastener Strength Charts. Bolt Markings and Torques - Metric Bolt Markings 8.8/8.9 10.9 12.9 Bolt Dia. N·m Ft. Lbs. N·m Ft. Lbs. N·m Ft.

FASTENER USAGE DESCRIPTION FASTENER USAGE WARNING: Use of an incorrect fastener may result in component damage or personal injury. Fasteners and torque specifications references in this Service Manual are identified in metric and SAE format. During any maintenance or repair procedures, it is important to salvage all fasteners (nuts, bolts, etc.) for reassem- bly. If the fastener is not salvageable, a fastener of equivalent specification must be used. THREADED HOLE REPAIR DESCRIPTION THREADED HOLE REPAIR Most stripped threaded holes can be repaired using a HelicoilT. Follow the vehicle or HelicoilT recommendations for application and repair procedures. INTERNATIONAL SYMBOLS DESCRIPTION - INTERNATIONAL SYMBOLS The graphic symbols illustrated in the following International Control and Display Symbols Chart are used to identify various instrument controls. The symbols correspond to the controls and displays that are located on the instrument panel. 6 INTRODUCTION WK

METRIC SYSTEM DESCRIPTION The metric system is based on quantities of one, ten, one hundred, one thousand and one million. The following chart will assist in converting metric units to equivalent English and SAE units, or vise versa.
