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.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

2.0L GASOLINE ENGINE
1. Engine coolant reservoir (P. 8-3)
2. Engine oil dipstick (P. 8-5)
3. Engine oil filler cap (P. 8-5)
4. Brake fluid reservoir (P. 8-7)5. Engine air cleaner filter (P. 8-13)
6. Battery (P. 8-9)
7. Fuse box (P. 8-17)
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.

•Keep the battery surface clean and dry. Clean
the battery with a solution of baking soda
and water.
•Make certain the terminal connections are
clean and securely tightened.
•If the vehicle is not used for 30 days or
longer, disconnect the
-negative battery
terminal cable to prevent discharge.
NOTE
Care should be taken to avoid situations that can
lead to potential battery discharge and potential
no-start conditions such as:
•Installation or extended use of electronic
accessories that consume battery power
when the engine is not running (Phone char-
gers, GPS, DVD players, etc).
•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.
WARNING
•Do not expose the battery to flames, an elec-
trical spark or a cigarette. Hydrogen gas
generated by the battery is explosive. Ex-
plosive gases can cause blindness or injury.
Do not allow battery fluid to contact your
skin, eyes, fabrics or painted surfaces. Sul-
furic acid can cause blindness or injury. Af-
ter touching a battery or battery cap, do not
touch or rub your eyes. Thoroughly wash
your hands. If the acid contacts your eyes,
skin or clothing, immediately flush with wa-
ter for at least 15 minutes and seek medical
attention.
•Do not operate the vehicle if the fluid in the
battery is low. Low battery fluid can cause a
higher load on the battery which can gener-
ate heat, reduce battery life, and in some
cases lead to an explosion.
•When working on or near a battery, always
wear suitable eye protection and remove all
jewelry.
•Battery posts, terminals and related acces-
sories contain lead and lead compounds.
Wash hands after handling.
•Keep battery out of the reach of children.
•Do not tip the battery. Keep the vent caps
tight and the battery level.

ommends to visually check the status of the
green indicator
A(if so equipped) periodically.
If it is not visible, replace the battery as soon as
possible.
MODELS WITH IDLE STOP/START
SYSTEM
•Ensure that the battery fitted is the special
battery that is enhanced with regard to the
charge-discharge capacity and life perfor-
mance. Avoid using any other battery for the
Idle Stop/Start System, as this may cause
early deterioration of the battery or a mal-
function of the Idle Stop/Start System. It isNDI1590

Protective plate for battery
WARNING
Whenever the battery is replaced, always have
the protective plate underneath the battery
also reinstalled or replaced. If this plate is not
reinstalled/replaced, in the event of a collision
a thermal incident could occur, causing vehicle
damage and potentially causing serious injury
of death.
If the vehicle battery is replaced, the protective
plate underneath the battery must also be
replaced. This protective plate must be fixed to
the underside of the replacement battery using
the adhesive tape supplied with the replace-
ment plate. It is recommended that you visit an
INFINITI dealer to purchase and replace the
protective plate underneath the battery.
1. Make sure the underside of the replacementbattery is dry and free of dust.
2. Remove the backing strips
