PRECAUTIONS < SERVICE INFORMATION >

SERVICE INFORMATION PRECAUTIONS Description

INFOID:0000000002953835

Observe the following precautions to ensure safe and proper servicing. These precautions are not described in each individual section.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

INFOID:0000000003425531

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 “SUPPLEMENTAL RESTRAINT SYSTEM” and “SEAT BELTS” of this Service Manual. 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 “SUPPLEMENTAL RESTRAINT SYSTEM”. • 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 harness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition 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 Necessary for Steering Wheel Rotation after Battery Disconnect INFOID:0000000003425532

NOTE: • Before removing and installing any control units, first turn the push-button ignition switch to the LOCK position, then disconnect both battery cables. • After finishing work, confirm that all control unit connectors are connected properly, then re-connect both battery cables. • Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work. If a DTC is detected, perform trouble diagnosis according to self-diagnosis results. This vehicle is equipped with a push-button ignition switch and a steering lock unit. If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned. If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure below before starting the repair operation.

OPERATION PROCEDURE 1.

2.

Connect both battery cables. NOTE: Supply power using jumper cables if battery is discharged. Turn the push-button ignition switch to ACC position. (At this time, the steering lock will be released.)

Revision: 2009 February

GI-2

2008 M35/M45


PRECAUTIONS < SERVICE INFORMATION > 3. Disconnect both battery cables. The steering lock will remain released with both battery cables disconnected and the steering wheel can be turned. GI 4. Perform the necessary repair operation. 5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering B wheel will lock when the push-button ignition switch is turned to LOCK position.) 6. Perform self-diagnosis check of all control units using CONSULT-III.

2008 M35/M45


PRECAUTIONS < SERVICE INFORMATION > • To prevent serious burns: Avoid contact with hot metal parts. Do not remove the radiator cap when the engine is hot. • Dispose of or recycle drained oil or the solvent used for cleaning parts in an appropriate manner. • Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically. Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire. • Clean all disassembled parts in the designated liquid or solvent prior to inspection or assembly. • Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new ones. • Replace inner and outer races of tapered roller bearings and needle bearings as a set. • Arrange the disassembled parts in accordance with their assembled locations and sequence. • Do not touch the terminals of electrical components which use microcomputers (such as ECM). Static electricity may damage internal electronic components. • After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection. • Use only the fluids and lubricants specified in this manual. • Use approved bonding agent, sealants or their equivalents when required. • Use hand tools, power tools (disassembly only) and recommended special tools where specified for safe and efficient service repairs. • When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.

SGI233

PBIC0190E

• Before servicing the vehicle: Protect fenders, upholstery and carpeting with appropriate covers. Take caution that keys, buckles or buttons do not scratch paint.

SGI234

WARNING: To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness connectors which are related to the engine control system and TCM (transmission control module) system. The connectors should be disconnected only when working according to the WORK FLOW of TROUBLE DIAGNOSES in EC and AT sections.

Precaution for Three Way Catalyst

INFOID:0000000002953840

If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To prevent this, follow the instructions. • Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst. • When checking for ignition spark or measuring engine compression, make tests quickly and only when necessary. • Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to the catalyst. Revision: 2009 February
