< PRECAUTION >
PRECAUTIONS
 Before jacking up the vehicle, apply wheel chocks or other tireblocks to the wheels to prevent t he vehicle from moving. After jack-
ing up the vehicle, support the vehicle weight with safety stands at
the points designated for proper lifting before working on the vehi-
cle.
These operations should be done on a level surface.
 When removing a heavy component such as the engine or tran- saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
 Before starting repairs which do not require battery power: Turn off ignition switch.
Disconnect the negative battery terminal.
 If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.
 To prevent serious burns: Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
 Dispose of drained oil or the solvent used for cleaning parts in an appropriate manner.
 Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray
and possibly a fire.
 Clean all disassembled parts in the designated liquid or solvent prior to inspection or assembly.
 Replace oil seals, gaskets, packings, O-rings, locking washers,
cotter pins, self-locking nuts, etc. with new ones.
 Replace inner and outer races of tapered roller bearings and needle bearings as a set.
 Arrange the disassembled parts in accordance with their assembled locations and sequence.
 Do not touch the terminals of electrical com ponents which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
 After disconnecting vacuum or air hoses, atta ch a tag to indicate the proper connection.
 Use only the fluids and lubricants specified in this manual.
 Use approved bonding agent, sealants or their equivalents when required.
 Use hand tools, power tools (disassembly only) and recommended special tools where specified for safe and efficient service repairs.
 When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leakage.

UNDER THE HOOD AND VEHICLE
The maintenance items listed here should
be checked periodically (e.g. each time you check the engine oil or refuel).
Seats Check seat position controls such as seat adjusters, seatback recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every po-
sition. Check that the head restrains move up and down smoothly and that the
locks (if equipped) hold securely in all latched positions. Check that the latches
lock securely for folding-down rear seatbacks. —
Seat belts Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters
and retractors) operate properly and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying, wear or damage. MA-34
Accelerator pedal
Check the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal. —
Brakes Check that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
booster Check the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Be sure to
keep the floor mats away from the pedal. BR-7
BR-15
Parking brake
Check that the lever or pedal has the proper travel and make sure that the ve-
hicle is held securely on a fairly steep hill when only the parking brake is ap-
plied. PB-3
Automatic transmis-
sion “Park” mecha-
nismCheck that the lock release button on the selector lever operates properly and
smoothly. On a fairly steep hill check that the vehicle is held securely with the
selector lever in the P (Park) position without applying any brakes.
—
Item
Reference page
Item Reference page
Windshield washer
fluid Check that there is adequate fluid in the tank. —
Engine coolant level Check the coolant level when the engine is cold. MA-12
Radiator and hosesCheck the front of the radiator and clean off any dirt, insects, leaves, etc., that
may have accumulated. Make sure the hoses have no cracks, deformation, de-
terioration or loose connections. MA-16
Brake fluid levels
Make sure that the brake fluid level is between the “MAX” and “MIN” lines on the
reservoir(s). MA-28
Battery
Check the fluid level in each cell. It should be between the “MAX” and “MIN”
lines. Vehicles operated in high temperatures or under severe conditions re-
quire frequent checks of the battery fluid level. PG-159
Engine drive belts
Make sure that no belt is frayed, worn, cracked or oily. MA-12
Engine oil levelCheck the level on the oil level gauge after parking the vehicle on a level spot
and turning off the engine. LU-7
Power steering fluid
level and linesCheck the level on the dipstick with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.
MA-32
Exhaust system
Make sure there are no loose supports, cracks or holes. If the sound of the ex-
haust seems unusual or there is a smell of exhaust fumes, immediately locate
the trouble and correct it. MA-21
Underbody
The underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these sub-
stances, otherwise rust will form on the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean those areas where mud and dirt
can easily accumulate. —
Fluid leaks Check under the vehicle for fuel, oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping from the air conditioner after use is
normal. If you should notice any leaks or gasoline fumes are evident, check for
the cause and correct it immediately. —

NOTE:
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts i
f found
damaged or if the auto belt tensioner reading reaches the maximum limit.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to FL section.
(4) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles (120,000
km) or 60 months. Use only Genu ine NISSAN Long Life Antifreeze/Coo lant (blue) or equivalent with proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water will reduce the life
expectancy of the factory-fill coolant.
(5) Periodic maintenance is not required. However, if valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perfo rm
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and inter vals are
required.

Fluids and LubricantsINFOID:0000000006220904
*1: For further details, see “Engine Oil Recommendation”.
*2: Using automatic transmission fluid other than Genuine NISSAN Matic S ATF will cause deterioration in driveability and autom atic
transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle limited wa rranty.
*3: DEXRON™ VI type ATF may also be used.
*4: Available in mainland U.S.A. through an INFINITI dealer.
*5: Using transfer fluid other t han Genuine NISSAN Transfer Fluid will damage the transfer , which is not covered by the INFINITI new
vehicle limited warranty. See an INFINITI retailer for recommended transfer fluid.
*6: For hot climates, Viscosity SAE 90 is suitable for ambient temperatures above 0 °C (32 °F)
*7: See an INFINITI dealer for service for synthetic oil.
*8: Using Hydraulic Suspen sion fluid other than Genuine NISSAN Hydraulic Susp ension fluid will damage the Hydraulic Suspension,
which is not covered by the INFINITI new vehicle limited warranty. See an INFINITI retailer for recommended hydraulic suspensio n fluid.
*9: The fluid capacity is the reference value.
Engine Oil RecommendationINFOID:0000000006287732
NISSAN recommends the use of an energy conservi ng oil in order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certification and International Lubri-
cant Standardization and Approval Committee (ILSAC) ce rtification and SAE viscosity standard. These oils
have the API certification mark on t he front of the container. Oils which do not have the specified quality label
should not be used as they could cause engine damage.
