A hat and safety shoes must be worn. 2 Vehicle protection Prepare a grille cover, fender cover, seat cover and floor mat before starting work. 3 Safety procedures When working with 2 or more persons, be sure to check the safety of one another. When working with the engine running, make sure to provide ventilation for exhaust fumes in the workshop. If working on high temperature, high pressure, rotating, moving or vibrating parts, wear appropriate safety equipment and take extra care not to injure yourself or others. When jacking up the vehicle, be sure to support the vehicle at the specified locations with safety stands. When lifting up the vehicle, use appropriate safety equipment. 4 Preparation of tools and measuring equipment Before starting work, prepare a tool stand, SST, measuring equipment, oil, and any replacement parts required.

5 Removal and installation, disassembly and assembly operations Diagnose with a thorough understanding of proper procedures and of the reported problem. Before removing any parts, check the general condition of the assembly and for deformation and damage. If the procedure is complicated, take notes. For example, note the total number of electrical connections, bolts or hoses removed. Add matchmarks to ensure reassembly of components in the original positions. Temporarily mark hoses and their fittings if needed. Clean and wash the removed parts if necessary and assemble them after a thorough check. 6 Removed parts Place the removed parts in a separate box to avoid mixing them up with new parts or contaminating the new parts. For non-reusable parts such as gaskets, O-rings and self-locking nuts, replace them with new ones as instructed in this manual. Retain the removed parts for customer inspection, if requested. 7* Checks to perform after work is finished Make sure that removed and installed parts (oil filler cap, level dipstick, floor mat, etc.) are properly installed/tightened. Make sure that none of the cloths or tools that were used have been left in the engine compartment or within the vehicle. Check that there are no oil leaks. CAUTION: *: Be sure to perform these checks properly, not performing these checks properly after finishing work can lead to a serious accident or injury. (b) JACKING UP AND SUPPORTING THE VEHICLE (1) Care must be taken when jacking up and supporting the vehicle. Be sure to lift and support the vehicle at the proper locations. (c) PRECOATED PARTS *a Seal Lock Adhesive (1) Precoated parts are bolts and nuts that are coated with seal lock adhesive at the factory. (2) If a precoated part is retightened, loosened or moved in any way, it must be recoated with the specified adhesive. (3) When reusing a precoated part, clean off the old adhesive and dry the part with compressed air. Then apply new seal lock adhesive appropriately to that part. (4) Some seal lock agents harden slowly. You may have to wait for the seal lock adhesive to harden. (d) SMALL-HEAD BOLTS (1) Small-head bolts are bolts with a smaller bolt head than standard bolts with the same thread diameter and flange diameter.

*A Example: M6 Bolt *a Ring Mark *b Black (2) Although the size of the bolt head is smaller than a standard bolt, the tightening torque remains unchanged as the thread diameter and flange diameter are not different. Make sure to tighten all small-head bolts to the correct torque indicated in the repair manual. (3) As the force applied to the sides of the head of a small-head bolt is higher than that of a standard bolt when the same tightening torque is used, the height of the bolt head has been increased to ensure its strength. (4) For identification purposes, small-head bolts are black and the bolt head is marked with a ring. (e) GASKETS (1) When necessary, use a sealant on gaskets to prevent leaks. (f) BOLTS, NUTS AND SCREWS (1) Carefully follow all of the specifications for tightening torque. Always use a torque wrench. (2) Make sure that no foreign matter (burrs, paint, etc.) gets trapped under the heads of the bolts and nuts when tightening them. (g) FUSES
