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

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 " SRS AIRBAG and SEAT BELTS " articles.

WARNINGTo 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 SRS AIRBAG . Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Information. 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

WARNINGWhen working near the Airbag Diagnosis Sensor Unit or other Airbag 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.

  1. Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface, Using scraper. Remove liquid gasket completely from the groove of the liquid gasket application surface, bolts, and bolt holes.
  2. Thoroughly clean the mating surfaces and remove adhering moisture, grease and foreign materials.
  3. Attach liquid gasket tube to Tool. Tool number : WS39930000 (-) Use Genuine RTV Silicone Sealant or equivalent. Refer to " «RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS»(ref-388039-S31807235822011022800000) ".
  4. Apply liquid gasket without breaks to the specified location with the specified dimensions. If there is a groove for the liquid gasket application, apply liquid gasket to the groove. As for the bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes. Make sure to read the text of service information. Within five minutes of liquid gasket application, install the mating component. If liquid gasket protrudes, wipe it off immediately. Do not retighten nuts or bolts after the installation. After 30 minutes or more have passed from the installation, fill engine oil and engine coolant. CAUTION: If there are specific instructions in this article, observe them.

OIL LEVEL

Note. Before starting the engine, check the oil level. If the engine is already started, stop it and allow 10 minutes before checking. Check that the oil level is within the range as indicated on the dipstick. If it is out of range, add oil as necessary until the dipstick indicates the correct level.

ENGINE OIL APPEARANCE

  1. Check engine oil for white milky appearance or excessive contamination.
  2. If engine oil becomes milky, it is highly probable that it is contaminated with engine coolant. Repair or replace damaged parts.

OIL LEAKAGE

Check for oil leakage around the following areas

  1. Oil pan
  2. Oil pan drain plug
  3. Oil pressure switch
  4. Oil filter
  5. Oil cooler
  6. IVT cover
  7. Front cover
  8. Mating surface between cylinder block and cylinder head
  9. Mating surface between cylinder head and rocker cover
  10. Crank oil seal (front and rear)

OIL PRESSURE CHECK

WARNINGBe careful not to burn yourself, as engine oil may be hot. Put the CVT shift selector in the Park "P" position.
