Workshop/Service Manual Workshop/service manuals contain service and repair information for all vehicle systems and components, except for major components such as engines, trans- missions, and rear axles. Each workshop/service manual section is divided into subjects that can include general information, principles of operation, removal, disassembly, assembly, installation, specifications, and troubleshooting. Maintenance Manual Maintenance manuals contain routine maintenance procedures and intervals for vehicle components and systems. They have information such as lubrication procedures and tables, fluid replacement procedures, fluid capacities, specifications, procedures for adjustments and for checking the tightness of fasteners. Maintenance manuals do not contain detailed repair or service information. Driver’s/Operator’s Manual Driver’s/operator’s manuals contain information needed to enhance the driver’s understanding of how to operate and care for the vehicle and its components.

Driver’s/ operator’s manuals do not contain detailed repair or service information. Service Bulletins Service bulletins provide the latest service tips, field repairs, product improve- ments, and related information. Some service bulletins are updates to information in the workshop/service manual. These bulletins take precedence over workshop/service manual information, until the latter is updated; at that time, the bulletin is usually canceled. The service bulletins manual is available only to dealers. When doing service work on a vehicle system or part, check for a valid service bulletin for the latest information on the subject. IMPORTANT: Before using a particular service bulletin, check the current service bulletin validity list to be sure the bulletin is valid.

Jacking WARNING Do not run the engine when jacking the vehicle. Contact of the wheels with the ground can cause the vehicle to move, which could result in personal injury. Support the vehicle prior to performing any pro- cedure requiring the vehicle to be jacked above the ground. Failure to properly support the vehicle could result in personal injury or damage to the vehicle. Make sure the jacks and jack stands are properly located to prevent the vehicle from falling. Failure to properly locate the jacks and jack stands could result in personal injury or damage to the vehicle. Wheel chocks must be used to prevent the vehicle from rolling and falling off the jack. Failure to properly chock the vehicle wheels could result in personal injury or damage to the vehicle. CAUTION If the vehicle is equipped with traction control, disable the traction system before performing any dynamic driveline maintenance, or damage to the traction control system could result. NOTE: To raise vehicles with floor jacks, follow the jack manufacturer’s recommendations for placement of the jack. Do not exceed the rated lift capacity of any jack. 1. See Fig. 1 for the front jacking points. 2. See Fig. 2 for the rear jacking points. Lifting CAUTION If the vehicle is equipped with traction control, disable the traction system before performing any dynamic driveline maintenance, or damage to the traction control system could result. Damage to the vehicle can occur if care is not used when positioning the hoist adaptors prior to lifting the vehicle. NOTE: Position the hoist adaptors for heavy- duty hoists according to the hoist manufacturer’s recommendations. Be sure the hoist has an ad- equate lifting capacity for the vehicle being lifted. 1. See Fig. 3 for the front lifting points. 2. See Fig. 4 for the rear lifting points. 01/08/98 f000871 Fig. 1, Front Jacking Points 06/11/98 f000872 Fig. 2, Rear Jacking Points 01/08/98 f000873 Fig. 3, Front Lifting Points Jacking and Lifting 00.00 Jacking and Lifting L-Line and A-Line Workshop Manual, Supplement 1, October 1998 050/1

IMPORTANT: See Subject 060 for the vehicle identification numbering system for vehicles built May 1, 2000, or later. Federal Motor Vehicle Safety Standard 115 specifies that all vehicles sold in the U.S. be assigned a 17- character Vehicle Identification Number (VIN). Using a combination of letters and numerals, the VIN de- fines the manufacturer, model, and major characteris- tics of the vehicle. See Table 1 for the character positions of a typical Sterling VIN, 480ALEBDXWA345678. The VIN can be found on the Vehicle Specification Decal (see the driver’s manual for decal location) and stamped on the outside of the left-hand frame rail about 24 to 40 inches (60 to 100 cm) aft of the front axle centerline. On Sterling vehicles built before July 1998, the VIN is stamped on the frame rail near the front axle position. IMPORTANT: A new VIN-code structure will be used for all vehicles built after April 30, 2000. Character positions 1 through 4 and 9 through 17 are nearly the same in both versions, but positions 5 through 8 have been assigned slightly different parameters. As a result, the build date of a vehicle must be determined before the VIN can be decoded. For all vehicles, a check digit (9th character) is determined by assignment of weighted values to the other 16 characters. These weighted values are processed through a series of equations designed to check validity of the VIN and to detect VIN alteration. NOTE: Always specify the VIN when ordering parts.
