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 of this Service Information.
| 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 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
| 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. |

CHECKING COOLING SYSTEM HOSES
Check hoses for the following
- Improper attachment
- Leaks
- Cracks
- Damage
- Loose connections
- Chafing
- Deterioration
Scheme 31
- Check that the reservoir tank engine coolant level is within the MAX (A) to MIN (B) range when the engine is cool.
- Adjust the engine coolant level if necessary. CAUTION: Refill the engine cooling system with the specified coolant or equivalent. Refer to " «FLUIDS AND LUBRICANTS»(ref-605940-S11091129442014032500000) ".
CHECKING COOLING SYSTEM FOR LEAKS
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 ".
Scheme 32
| WARNING | Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure coolant escaping from the radiator. |
| CAUTION | Higher test pressure than specified may cause radiator damage. |
Cooling fan and shroud
Inspect cooling fan and shroud for nicks, cracks, breaks and warping. Replace if necessary.
Water Inlet
After installation, attach the water inlet clip (A) on the oil level gauge guide (1) positioned at location (B) as shown below.
