When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to yourself
or damage to the vehicle. The following are
general precautions which should be closely
observed.
WARNINGO Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
N (Neutral) position. For an automatic
transmission, move the selector lever
to P (Park) position.
O Be sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.
O If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.
O It is advised to secure or remove any loose clothing and any jewelry, such
as rings, watches, etc. before work-
ing on your vehicle.
O Always wear eye protection when-
ever you work on your vehicle.
O If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
O Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
O Keep smoking materials, flame and
sparks away from fuel and the bat-
tery.
O On gasoline engine models with the
Multiport Fuel Injection (MFI) System,
the fuel filter or fuel lines should be
serviced by an INFINITI retailer be-
cause the fuel lines are under high
pressure even when the engine is off. CAUTION O Do not work under the hood while the
engine is hot. Turn off the engine and
wait until it cools down.
O Never connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
O Never leave any engine or automatic
transmission related component har-
ness connector disconnected while
the ignition key is on.
O Avoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid.
This ª8. Do-it-yourselfº section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.

O Check your local regulations.
4. Loosen the oil filter with an oil filter wrench.
Remove the oil filter by turning it by hand.
5. Wipe the engine oil filter mounting surface
with a clean rag.
Be sure to remove any old rubber gasket
remaining on the mounting surface of
the engine.
6. Coat the gasket on the new filter with clean
engine oil.
7. Screw in the oil filter clockwise until a slight
resistance is felt, then tighten additionally
more than 2/3 turn.
Oil filter tightening torque:
11 to 15 ft-lb
(14.7 to 20.5 N z m)
8. Clean and re-install the drain plug with a
new washer. Securely tighten the drain plug
with a wrench.
Drain plug tightening torque:
22 to 29 ft-lb
(29 to 39 N z m)
Do not use excessive force.
9. Refill engine with recommended oil and
install the cap securely. CAUTION The dipstick must be inserted in place to
prevent oil spillage from the dipstick
hole while filling the engine with oil.
See ªCapacities and recommended fuel/
lubricantsº in the ª9. Technical and con-
sumer informationº section for drain and
refill capacity. The drain and refill capacity
depends on the oil temperature and drain
time. Use these specifications for reference
only. Always use the dipstick to determine
the proper amount of oil in the engine.
CAUTION When filling oil, do not pull out the
dipstick.
10.Start the engine and check for leakage
around the drain plug and the oil filter.
Correct as required.
11.Turn the engine off and wait more than 10
minutes. Check the oil level with the dip-
stick. Add engine oil if necessary. After the operation 1. Install the engine undercover into position
as the following steps.
a. Pull the center of the small plastic clip out.
b. Hold the engine undercover into position.
c. Insert the clip through the undercover into
the hole in the frame, then push the center
of the clip in to lock the clip in place.
d. Install the other bolts that hold the under-
cover in place. Be careful not to strip the
bolts or over-tighten them.
2. Lower the vehicle carefully to the ground.
3. Dispose of waste oil and filter properly.
WARNING O Prolonged and repeated contact with
used engine oil may cause skin can-
cer.
O 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.

If maintenance is required, see your INFINITI
retailer for servicing.
The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals. See ªPeriodic maintenance
schedulesº in the ª9. Maintenanceº section for
maintenance intervals. When replacing the
filter, wipe the inside of the air cleaner housing
and the cover with a damp cloth.
WARNINGO Operating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine backfires. If it is not
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed and be care-
ful when working on the engine with
the air cleaner removed.
O Never pour fuel into the throttle body
or attempt to start the engine with the
air cleaner removed. Doing so could
result in serious injury. CAUTION O After wiper blade replacement, return
the wiper arm to its original position.
Otherwise it may be damaged when
the engine hood is opened.
O Make sure the wiper blade contacts
the glass, otherwise the arm may be
damaged from wind pressure.
O Worn windshield wiper blades can
damage the windshield and impair
driver vision.
CLEANING If your windshield is not clear after using the
windshield washer or if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your
windshield is clean if beads do not form when
rinsing with clear water.
Clean the blade by wiping it with a cloth
soaked in a washer solution or a mild deter- gent. Then rinse the blade with clear water. If
your windshield is still not clear after cleaning
the blades and using the wiper, replace the
blades.

EXPLANATION OF MAINTENANCE
ITEMS Additional information on the following
items with ª*º is found in the ª8. Do-it-
yourselfº section.
Emission control system
maintenance Drive belts*: Check drive belts for wear, fray-
ing or cracking and also for proper tension.
Replace the drive belts if found damaged.
Air cleaner filter: Under normal driving con-
ditions, the air cleaner filter should be replaced
in accordance with the maintenance schedule.
However, driving the vehicle in dusty areas
may cause more rapid clogging of the element.
Consequently, the element may have to be
replaced more frequently.
EVAP vapor lines: Check vapor lines and
connections for failure or looseness. If leaks
are found, replace them.
Fuel lines: Check the fuel hoses, piping and
connections for leaks, looseness or deteriora-
tion. Replace any parts if they are damaged.
Engine coolant*: Drain and flush the cooling
system.
Engine oil & oil filter*: Under normal driving conditions, the engine oil and oil filter should
be replaced in accordance with the mainte-
nance schedule. However, under severe driv-
ing conditions, they may have to be replaced
more frequently.
Spark plugs*: Replace with new plugs having
the correct heat range.
Chassis and body maintenance Brake lines & cables: Check the brake lines
and hoses (including brake booster vacuum
hoses, connections & check valve) and park-
ing brake cables for proper attachment, leaks,
cracks, chafing, abrasion, deterioration, etc.
Brake pads & rotors: Check these and the
other neighboring brake components for wear,
deterioration and leaks. Under severe driving
conditions, they may have to be inspected
more frequently.
Automatic transmission fluid*: Using auto-
matic transmission fluid other than Genuine
Nissan ATF Matic Fluid J will cause deteriora-
tion in driveability and automatic transmission
durability, and may damage the automatic
transmission, which is not covered by the
INFINITI new vehicle limited warranty. If
checking or replacement is required, we rec-
ommend your INFINITI retailer for servicing.
Under severe driving conditions, the fluid should be replaced at the specified interval.
Manual transmission oil & differential gear
oil*: Check the oil level and visually inspect for
signs of leakage.
Under severe driving conditions, the oil should
be replaced at the specified interval.
Steering gear & linkage, axle & suspension
parts: Check for damage, looseness and leak-
age of oil or grease. Under severe driving
conditions, more frequent inspection should be
performed.
Exhaust system: Visually check the exhaust
pipes, muffler, and hangers for proper attach-
ment, leaks, cracks, chafing, abrasion, dete-
rioration, etc. Under severe driving conditions,
inspection should be performed more fre-
quently.
In-cabin microfilter: Under normal condi-
tions, this microfilter should be replaced in
accordance with the maintenance schedule.
However, in some situations, the microfilter
may clog more rapidly (depending on the air
conditioner's working environment). If this hap-
pens, the air flow may decrease, or the win-
dows may fog up easily when the air condi-
tioner is in use, the microfilter should be
replaced immediately at your INFINITI retailer.
