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 (Fig. 1) and (Fig. 2). KJ INTRODUCTION 1

FASTENER USAGE DESCRIPTION DESCRIPTION - FASTENER USAGE WARNING: USE OF AN INCORRECT FASTENER MAY RESULT IN COMPONENT DAMAGE OR PER- SONAL 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 reassembly. If the fastener is not salvageable, a fastener of equivalent specification must be used. DESCRIPTION - THREADED HOLE REPAIR Most stripped threaded holes can be repaired using a Helicoilt. Follow the vehicle or Helicoilt recommen- dations for application and repair procedures. INTERNATIONAL SYMBOLS DESCRIPTION The graphic symbols illustrated in the following International Control and Display Symbols Chart (Fig. 3) are used to identify various instrument controls. The symbols correspond to the controls and dis- plays that are located on the instrument panel.

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.

TORQUE REFERENCES DESCRIPTION Individual Torque Charts appear within many or the Groups. Refer to the Standard Torque Specifica- tions Chart for torque references not listed in the individual torque charts (Fig. 5). Fig. 5 TORQUE SPECIFICATIONS KJ INTRODUCTION 7

VEHICLE EMISSION CONTROL INFORMATION (VECI) LABEL DESCRIPTION All models have a Vehicle Emission Control Infor- mation (VECI) Label. DaimlerChrysler permanently attaches the label in the engine compartment (Fig. 6). The label cannot be removed without defacing label information and destroying label. The label contains the vehicle’s emission specifications and vacuum hose routings. All hoses must be connected and routed according to the label. 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. The VECI label contains the following: • Engine family and displacement • Evaporative family • Emission control system schematic • Certification application • Engine timing specifications (if adjustable) • Idle speeds (if adjustable) • Spark plug and gap VEHICLE IDENTIFICATION NUMBER DESCRIPTION The Vehicle Identification Number (VIN) plate is located on the lower left A-pillar and is visible through the windshield (Fig. 7). The VIN contains 17 characters that provide data concerning the vehicle. Refer to the VIN decoding chart to determine the identification of a vehicle. The Vehicle Identification Number is also imprinted on the: • Vehicle Safety Certification Label. • Frame rail. 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 Iden- tification Number. The check digit is used by the manufacturer and government agencies to verify the authenticity of the vehicle and official documenta- tion. The formula to use the check digit is not released to the general public.

The label certifies that the vehicle conforms to all applicable Federal Motor Vehicle Safety 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. Fig. 8 VEHICLE SAFETY CERTIFICATION LABEL - TYPICAL KJ INTRODUCTION 9 VEHICLE IDENTIFICATION NUMBER (Continued)
