Nissan Maxima Service and Repair Manual: Precaution

PRECAUTIONS

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 SR and SB section 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 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 harness 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 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.

General Precaution

WARNING: When replacing fuel line parts, be sure to observe the following.

  •  Put a "CAUTION: FLAMMABLE" sign in the work area.
  •  Be sure to work in a well ventilated area and have a CO2 fire extinguisher.
  •  Do not smoke while working on the fuel system. Keep open flames and sparks away from the work area.

CAUTION:

  • - Before removing fuel line parts, carry out the following procedures:
  •  Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in safe area.
  •  Release fuel pressure from the fuel lines. Refer to EC-592, "Inspection".
  •  Disconnect the battery ground cable.
  •  Always replace O-rings and clamps with new ones.
  •  Do not kink or twist tubes when they are being installed.
  •  Do not tighten hose clamps excessively to avoid damaging hoses.

Nissan Maxima. General Precaution

  • After connecting the fuel tube quick connectors, make sure the quick connectors are secure.

    Check that the connector and resin tube do not contact any adjacent parts.

  • a) Apply fuel pressure to the fuel system by turning the ignition switch to ON (without starting the engine). Then check for fuel leaks at the fuel tube connections.
  • b) Start the engine and rev the engine, then check for fuel leaks at the fuel tube connections.
  • After installing the tubes, run the engine and check for fuel leaks at the connections.
  • Use only a Genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the MIL may come on.
  • For servicing "Evaporative Emission System" parts, refer to EC-94, "System Description".
