PRECAUTIONS PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BKS002B7
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 and SB section of
this Service Manual.
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 per-
formed by an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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
harness connectors.
General Precautions for Service OperationsBKS002B8
Never work with wet hands.
Xenon headlamp includes high voltage generating part. Be sure
to disconnect battery negative cable (negative terminal) or
power fuse before removing, installing, or touching the xenon
headlamp (including lamp bulb).
Turn the lighting switch OFF before disconnecting and connect-
ing the connector.
When turning the xenon headlamp on and while it is illuminated,
never touch the harness, bulb, and socket of the headlamp.
When checking the headlamp on/off operation, check it on vehi-
cle and with the power connected to the vehicle-side connector.
Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not
touch the headlamp bulb just after the headlamp is turned off, because it is very hot.
Install the xenon headlamp bulb socket correctly. If it is installed
improperly, high-voltage leak or corona discharge may occur
that can melt the bulb, connector, and housing. Do not illuminate
the xenon headlamp bulb out of the headlamp housing. Doing
so can cause fire and harm your eyes.
When the bulb has burned out, wrap it in a thick vinyl bag and
discard. Do not break the bulb.
Leaving the bulb removed from the headlamp housing for a long
period of time can deteriorate the performance of the lens and
reflector (dirt, clouding). Always prepare a new bulb and have it
on hand when replacing the bulb.
Do not use organic solvent (paint thinner or gasoline) to clean
lamps and to remove old sealant.

NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within
the range shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE
Check engine oil for white turbidity or heavy contamination.
If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.
Oil pan
Oil pan drain plug
Oil pressure switch
Oil filter
Intake valve timing control cover and intake valve timing control solenoid valve
Front cover
Mating surface between cylinder block and lower cylinder block
Mating surface between cylinder block and cylinder head
Mating surface between cylinder head and rocker cover
Crankshaft oil seals (front and rear)
OIL PRESSURE CHECK
WARNING:
Be careful not to burn yourself, as engine oil may be hot.
Engine oil pressure check should be in “ Parking position”.
1. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove splash guard (RH).
3. Disconnect harness connector at oil pressure switch, and
remove oil pressure switch using deep socket (commercial ser-
vice tool).

Periodic MaintenanceBLS0008Z
The following tables show the normal maintenance schedule. Depending upon weather and atmospheric con-
ditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent mainte-
nance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.
ENGINE AND EMISSION CONTROL MAINTENANCE
(Annual Mileage <30,000 Km [18,000 miles]/year)
QR and VQ ENGINE
Abbreviations: I = Inspect and correct or replace as necessary, R = Replace
[ ] = At the specified distance only
NOTE:
(1) Periodic maintenance is not required. However, if valve noise increases, check valve clearance.
(2) Replace the drive belt if found damaged or if the auto tensioner reading (for QR20DE engine) reaches the maximum
limit.
(3) First replace at 100,000 km (60,000 miles)/60 months, then every 60,000 km (36,000 miles)/48 months. Perform “I”
(Checking the mixture ratio and correcting the mixture ratio if necessary) at the middle of replacement interval.
(4) Fuel filter is maintenance-free. For service procedures, refer to FL section.
(5) Perform only according to “Maintenance Under Severe Driving Conditions” for models without Euro-OBD system.
Maintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”. MAINTENANCE OPERATIONMAINTENANCE INTERVAL Reference page
