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. Information necessary to service the system safely is included in the SRS AIRBAG and SEAT BELTS article of this Service Information.

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 three minutes before performing any service.

CHECKING COOLING SYSTEM HOSES

Check hoses for the following

  1. Improper attachment
  2. Leaks
  3. Cracks
  4. Damage
  5. Loose connections
  6. Chafing
  7. Deterioration

CHECKING RESERVOIR LEVEL

  1. Check that the reservoir tank engine coolant level is within the MAX (A) to MIN (B) range when the engine is cool.
  2. Adjust the engine coolant level if necessary. CAUTION: Refill the engine cooling system with the specified coolant or equivalent. Refer to " «RECOMMENDED FLUIDS AND LUBRICANTS»(ref-675584-S23480474382014120500000) ".

CHECKING COOLING SYSTEM FOR LEAKS

WARNINGDo not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly push down and turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down and turning it all the way.
CAUTIONPerform this step when the engine is cold. Do not spill engine coolant on drive belt.

To check for leaks, apply pressure to the cooling system using suitable tool (A) and Tool (B).

Tool number (B): EG17650301 (J-33984-A)

Testing pressure: Refer to " RADIATOR: INSPECTION ".
