Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951682
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 mi nutes before performing any service.
Precaution for Liquid GasketINFOID:0000000009461023
REMOVAL OF LIQUID GASKET
• After removing the bolts and nuts, separate the mating surface and
remove the liquid gasket using Tool (A).
CAUTION:
Be careful not to damage the mating surfaces.
• In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use a
plastic hammer to slide (2) the cutter by tapping on the side.
CAUTION:
Do not damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the gasket application surface and the mating surface.
• Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating surface and remove adhering moisture, grease and foreign
materials.
3. Attach the liquid gasket tube to the tube presser. Use Genuine Silicone RTV Seal ant or equivalent. Refer to
GI-21, "Recommended Chemical Products and Sealants"
.

InspectionINFOID:0000000009461028
OIL LEVEL
• Before starting the engine, check the oil level. If t
he engine is already started, stop it and allow 10 minutes
before checking.
• Check that the oil level is within the range (A) on the oil level
gauge.
• If it is out of range, add oil as necessary.
ENGINE OIL APPEARANCE
• Check engine oil for white milky appearance or excessive contamination.
• If engine oil becomes milky, it is highly probable t hat it is contaminated with engine coolant. Repair or
replace damaged parts.
OIL LEAKAGE
Check for oil leakage around the following areas:
•Oil pan
• Oil pan drain plug
• Oil pressure switch
• Oil filter
• Oil cooler
• Valve timing control cover and valve timing control solenoid valve
• Front cover
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and rocker cover
• Crankshaft oil seal (front and rear)
OIL PRESSURE CHECK
WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• Put the CVT shift selector in the Park "P" position.
1. Check engine oil level. Refer to OIL LEVEL.
2. Remove fender protector side cover (RH). Refer to EXT-26, "FENDER PROTECTOR : Exploded View"
.
3. Disconnect oil pressure switch harness connector at oil pressure switch. Remove oil pressure switch and install Tools.
CAUTION:
Do not drop or shock oil pressure switch.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load, using Tool. NOTE:

ENGINE OIL
• When engine oil temperature is low, engine oil pressure becomes high.
• If difference is extreme, check oil passage and oil pump for oil leaks.
6. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch.
b. Apply liquid gasket and tighten oil pressure switch to the specification. Use Genuine RTV Silicone Sealant or equivalent.
c. After warming up engine, make sure there are no engine oil leaks.
7. Install fender protector side cover (RH). Refer to EXT-26, "FENDER PROTECTOR : Exploded View"
.
Changing Engine OilINFOID:0000000009461029
WARNING:
• Be careful not to burn yourself, as the 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. Position the vehicle so it is level on the hoist.
2. Warm up the engine and check for oil leaks from the engine.
3. Stop engine and wait for 10 minutes.
4. Remove the oil pan drain plug (1) and oil filler cap.
5. Drain the engine oil.
6. Install the oil pan drain plug with a new washer and refill the engine with new engine oil.
CAUTION:
• Be sure to clean the oil pan drain plug and install using a new washer.
• The refill capacity depends on the oil temper ature and drain time. Use these specifications for
reference only. Always use the oil level gauge to determine when the proper amount of oil is in
the engine.
7. Warm up the engine and check around the drain plug and oil filter for oil leaks.
8. Stop the engine and wait for 10 minutes.
9. Check the oil level using the oil level gauge. CAUTION:
Do not overfill the engine with engine oil. Engine oil pressure : Refer to
LU-18, "Oil Pressure"
Oil pressure switch : Refer to EM-28, "Exploded View"
