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 of this Service Information.
| WARNING | Always observe the following items for preventing accidental activation. To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that 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 " SRS AIRBAG ". Never 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 | Always observe the following items for preventing accidental activation. When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never 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. |

- After removing mounting nuts and bolts, separate the mating surface using the seal cutter [SST: KV10111100 (J-37228)] (A) and remove old liquid gasket sealing. CAUTION: Be careful not to damage the mating surfaces.
- Tap (B) the seal cutter [SST: KV10111100 (J-37228)] to insert it, and then slide (C) it by tapping on the side as shown in the figure below.
- In areas where seal cutter [SST: KV10111100 (J-37228)] is difficult to use, use a plastic hammer to lightly tap the parts, to remove it. CAUTION: If for some unavoidable reason tool such as a screwdriver is used, be careful not to damage the mating surfaces.

- Using a scraper (A), remove old liquid gasket from liquid gasket application surface and the mating surface. Remove liquid gasket completely from the groove of the liquid gasket application surface, mounting bolts, and bolt holes.
- Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating use) to remove moisture, grease and foreign materials.
- Attach liquid gasket tube to the tube presser (commercial service tool). Use Genuine RTV Silicone Sealant or equivalent. Refer to " «RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS»(ref-672611-S40047121162014112400000) ".
- 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 (B), normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes. Check 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. Never retighten after mounting bolts and nuts 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 information, observe them. |

- Check if the reservoir tank engine coolant level is within the "MIN" to "MAX" when the engine is cool.
- Adjust the engine coolant level if necessary. CAUTION: Refill Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent in its quality mixed with water (distilled or demineralized). Refer to " «RECOMMENDED FLUIDS AND LUBRICANTS»(ref-672624-S37238398562014112400000) ".

- To check for leakage, apply pressure to the cooling system with the radiator cap tester (commercial service tool) (A) and radiator cap tester adapter (commercial service tool) (B). Testing pressure: Refer to " «RADIATOR»(ref-672622-S33308841112014112400000) ". WARNING: Never remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine coolant escaping from engine cooling system. CAUTION: Higher test pressure than specified may cause radiator damage. NOTE: In a case that engine coolant decreases, replenish radiator with engine coolant.
- If anything is found, repair or replace damaged parts.
Radiator Upper Clip
Install each radiator upper clips on radiator core connection as follows
Scheme 37
- Install each mounting rubbers (upper) (1) on mounting pins (A) of radiator.
- Align each radiator upper clips (2) with radiator core connection (B), then insert each radiator upper clips straight into radiator core connections until a click is heard.
- After connecting each radiator upper clips, use the following method to check it is fully connected. Visually confirm that each radiator upper clips are connected to radiator core connections. Move each radiator upper clips and the radiator forward and backward to check they are securely connected.
Reservoir tank
Note. Insert reservoir tank straight to the mounting position.
Radiator hose
Note. Insert the radiator hose (1) all the way to the stopper (2) or by 33 mm (1.30 in) (hose without a stopper).
