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 Man- ual. 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 har- ness connectors. Precaution for Liquid Gasket INFOID:0000000001308809 REMOVAL OF LIQUID GASKET SEALING  After removing the bolts and nuts, separate the mating surface and remove the old liquid gasket sealing using Tool. CAUTION: Do not damage the mating surfaces.  Tap the seal cutter to insert it.  In areas where the Tool is difficult to use, lightly tap to slide it. LIQUID GASKET APPLICATION PROCEDURE 1. Remove the old liquid gasket adhering to the gasket application surface and the mating surface using suitable tool.  Remove the 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 material. Tool number : KV10111100 (J-37228) WBIA0566E PBIC0003ELU-4[VQ40DE] PRECAUTIONS 3. Attach the liquid gasket tube to the Tool. Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-26, “Recommended Chemical Products and Sealants“. 4. Apply the liquid gasket without breaks to the specified location with the specified dimensions.  If there is a groove for the liquid gasket application, apply the liquid gasket to the groove.  As for the bolt holes, normally apply the liquid gasket inside the holes. If specified in the procedure, it should also be applied outside the holes.  Within five minutes of liquid gasket application, install the mat- ing component.  If the liquid gasket protrudes, wipe it off immediately.  Do not retighten after the installation.  Wait 30 minutes or more after installation before refilling the engine with engine oil and engine coolant. CAUTION: If there are specific instructions in this manual, observe them.

If the engine is already running, turn it off and allow 10 minutes before checking.  Pull out oil level gauge and wipe clean.  Insert oil level gauge.  Check that the oil level is within the low (L) and high (H) range as indicated on the dipstick.  If the engine oil level is out of range, add oil as necessary. Refer to MA-10, “Fluids and Lubricants“. CAUTION: Do not overfill the engine with oil. OIL APPEARANCE  Check the engine oil for a white milky appearance or excessive contamination.  If the engine oil is 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:  Oil pans (lower and upper)  Oil pan drain plug  Oil pressure switch  Oil filter  Oil cooler  Water pump cover  Chain tensioner cover  Intake valve timing control cover and intake valve timing control solenoid valve  Mating surface between cylinder block and cylinder head  Mating surface between lower cylinder block and cylinder block  Mating surface between cylinder head and rocker cover  Mating surface between front timing chain case and rear timing chain case  Mating surface between rear timing chain case and cylinder head  Mating surface between rear timing chain case and cylinder block  Mating surface between rear timing chain case and lower cylinder block  Mating surface between rear timing chain case and oil pan (upper)  Crankshaft oil seals (front and rear)  Oil level gauge guide  Camshaft position sensor (PHASE) OIL PRESSURE CHECK WARNING:  Be careful not to burn yourself, as the engine and engine oil may be hot.  Put the selector lever in the Park “P“ position. 1. Check engine oil level. Refer to LU-8, “Inspection“. 2. Remove engine undercover using power tool. PBIC2823EENGINE OIL LU-9[VQ40DE] C D E F G H I J K L M A LU N P O 3. Disconnect harness connector at oil pressure switch (B), and remove oil pressure switch (B). CAUTION: Do not drop or shock oil pressure switch.  A: Oil pan (upper)  ?: Front 4. Install Tools. 5. Start engine and warm it up to normal operating temperature. 6. Check oil pressure with engine running under no-load. NOTE: When engine oil temperature is low, engine oil pressure becomes high. Engine oil pressure [Engine oil temperature at 80°C (176°F)] Unit: kPa (kg/cm 2 , psi) CAUTION: If the difference is extreme, check the oil passages and oil pump for leaks and blockages. 7. After the inspections, install oil pressure switch as follows: a. Remove old liquid gasket adhering to oil pressure switch and engine. b. Apply liquid gasket and tighten oil pressure switch to the specification. Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-26, “Recommended Chemical Prod- ucts and Sealants“. c. After warming up engine, make sure there is no leakage of engine oil with running engine. Changing Engine Oil INFOID:0000000001308913 WARNING:  Be careful not to burn yourself, as the engine and engine oil may be hot.  Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct skin contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible. 1. Warm up the engine, and check for any oil leaks. 2. Stop the engine and wait for at least 10 minutes. 3. Remove the oil drain plug and oil filler cap to drain the old oil. 4. Install a new washer on the oil drain plug, then install the oil drain plug in the oil pan.

Do not allow engine oil to adhere to drive belts.  Completely wipe off any engine oil that adheres to the engine and the vehicle. INSTALLATION 1. Remove foreign materials adhering to the oil filter seal mating surface. 2. Apply clean engine oil to the oil filter seal circumference of the new oil filter as shown. 3. Screw on the oil filter manually until it touches the installation surface, then tighten it by 2/3 turn as shown. Or tighten to speci- fication. 4. Inspect the engine for oil leaks. Refer to LU-11, “Removal and Installation“. 5. Install the engine undercover using power tool. INSPECTION AFTER INSTALLATION 1. Check the engine oil level. Refer to LU-8, “Inspection“. 2. Start the engine and check for engine oil leaks. 3. Stop the engine and wait for 10 minutes. 4. Check the engine oil level and adjust the engine oil level as required.
