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 gen-
eral precautions which should be closely ob-
served.
WARNING
•Park the vehicle on a level surface, apply the
parking brake securely and block the
wheels to prevent the vehicle from moving.
Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the en-
gine is hot. Always turn off the engine and
wait until it cools down.
•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.
•It is advisable to secure or remove any loose
clothing and any jewelry, such as rings,
watches, etc. before working on your ve-
hicle.
•If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to es-
cape.
•Never get under the vehicle while it is sup-
ported by a jack.
•Keep smoking materials, flame and sparks
away from fuel and the battery.
•Never connect or disconnect either the bat-
tery or any transistorized component con-
nector while the ignition switch is in the ON
position.
•On gasoline engine models with the Multi-
port Fuel Injection system, the fuel filter and
fuel lines should be serviced by an INFINITI
retailer or qualified workshop because the
fuel lines are under high pressure even
when the engine is turned off.
•Your vehicle is equipped with an automatic
engine cooling fan. It may come on at any
time without warning, even if the ignition
switch is in the OFF position and the engine
is not running. To avoid injury, always dis-
connect the negative battery cable before
working near the fan.
•Always wear eye protection whenever you
work on your vehicle.
•Never leave the engine or the transmission
related component harness connector dis-
connected while the ignition switch is in the
ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle flu-
ids can hurt the environment. Always con-
form to local regulations for disposal of ve-
hicle fluids.
This “ 8. Do-it-yourself” section provides in-
structions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage. If in doubt about any
servicing, it is recommended you have it done by
an INFINITI retailer.

8. Window washer fluid reservoir (P. 8-8)
WARNING
The engine cooling system is filled at the fac-
tory with a high-quality, year-round, antifreeze
coolant solution. The antifreeze solution con-
tains rust and corrosion inhibitors, therefore
additional cooling system additives are not
necessary.
•Never remove the radiator or coolant reser-
voir cap when the engine is hot. Wait until
the engine and radiator cool down. Serious
burns could be caused by high-pressure
fluid escaping from the radiator. For addi-
tional information on precautions, refer to
If your vehicle overheats
in the6. In case
of emergency section
•The engine coolant reservoir tank is
equipped with a pressure type cap. To pre-
vent engine damage, use only a genuine
INFINITI pressure cap.
CAUTION
•Never use any cooling system additives
such as radiator sealer. Additives may clog
the cooling system and cause damage to
the engine, transmission and/or cooling
system.

nance intervals or during the break-in period,
depending on the severity of operating condi-
tions.
CAUTION
The oil level should be checked regularly. Op-
erating the engine with an insufficient amount
of oil can damage the engine, and such dam-
age is not covered by the warranty.
CHANGING ENGINE OIL
WARNING

Also make sure that the vehicle is held securely
on a fairly steep hill when only the parking
brake is applied. If the parking brake needs
adjustment, it is recommended you visit an
INFINITI retailer for this service.
Seats
:
Check seat position controls such as seat ad-
justers, seatback recliner, etc. to ensure they
operate smoothly and that all latches lock
securely in every position. Check that the head
restraints move up and down smoothly and that
the locks (if so equipped) hold securely in all
latched positions.

:
Check that all parts of the seat belt system (for
example, buckles, anchors, adjusters and re-
tractors) operate properly and smoothly, and
are installed securely. Check the belt webbing
for cuts, fraying, wear or damage.
Steering wheel
:
Check for changes in the steering condition,
such as excessive free play, hard steering or
strange noises.Warning lights and chimes
:
Make sure that all warning lights and chimes
are operating properly.
Windshield defroster
:
Check that the air comes out of the defroster
outlets properly and in good quantity when
operating the heater or air conditioner.
Windshield wiper and washer*
:
Check that the wipers and washer operate
properly and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*
:
Except for maintenance free battery, check the
fluid level in each cell. It should be between the
“UPPER” and “LOWER” lines. Vehicles operated
in high temperatures or under severe condi-
tions require frequent checks of the battery
fluid level.
NOTE
Care should be taken to avoid situations that can
lead to potential battery discharge and potential
no-start conditions such as:
1. Installation or extended use of electronic ac-
cessories that consume battery power when
the engine is not running (Phone chargers,
GPS, DVD players, etc.)
2. Vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*
:
Make sure that the brake fluid level is between
the “MAX” and “MIN” lines on the reservoir.
Coolant level*
:
Check the coolant level when the engine is cold.
Engine drive belt(s)*
:
Make sure that no belt is frayed, worn, cracked
or oily.
