PRECAUTIONS DLN-159 < PRECAUTION > [FRONT FINAL DRIVE: M205] C E F G H I J K L M A B DLN N O P PRECAUTION PRECAUTIONS Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT INFOID:0000000006179538 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the SR and SB section of this Service Man- ual. WARNING: • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. • Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SR section. • Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har- ness connectors. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: • When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni- tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Precaution for Servicing Front Final Drive INFOID:0000000006179539 • Before starting diagnosis of the vehicle, understand the symptoms well. Perform correct and systematic operations. • Check for the correct installation status prior to removal or disassembly. When matching marks are required, be certain they do not interfere with the function of the parts they are applied to. • Overhaul should be done in a clean work area, a dust proof area is recommended. • Before disassembly, completely remove sand and mud from the exterior of the unit, preventing them from entering into the unit during disassembly or assembly. • Always use shop paper for cleaning the inside of components. • Avoid using cotton gloves or a shop cloth to prevent the entering of lint. • Check appearance of the disassembled parts for damage, deformation, and abnormal wear. Replace them with new ones if necessary. • Gaskets, seals and O-rings should be replaced any time the unit is disassembled. • Clean and flush the parts sufficiently and blow them dry. • Be careful not to damage sliding surfaces and mating surfaces. • When applying sealant, remove the old sealant from the mating surface; then remove any moisture, oil, and foreign materials from the application and mating surfaces. • In principle, tighten nuts or bolts gradually in several steps working diagonally from inside to outside. If a tightening sequence is specified, observe it. • During assembly, observe the specified tightening torque. • Add new differential gear oil, petroleum jelly, or multi-purpose grease, as specified. |
