When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
•Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. 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
engine is hot. Always turn off the engine
and wait until it cools down.
•If you must work with the engine run-
ning, 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 vehicle.
•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.
•Never get under the vehicle while it is
supported by a jack.
•Keep smoking materials, flame and
sparks away from fuel and the battery.
•Never connect or disconnect either the
battery or any transistorized compo-
nent connector while the ignition switch
is in the ON position.
•On gasoline engine models with the
Multiport Fuel Injection system, the fuel
filter and fuel lines should be serviced by
an INFINITI retailer or qualified work-
shop because the fuel lines are under
high pressure even when the engine is
turned off.
•Your vehicle is equipped with an auto-
matic 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 disconnect 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 transmis-
sion related component harness connec-
tor disconnected 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
fluids can hurt the environment. Always
conform to local regulations for disposal
of vehicle 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 af-
fect 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

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 malfunction of the Idle Stop/Start Sys-
tem. It is recommended that a Genuine
INFINITI battery is fitted. For more infor-
mation, it is recommended that you con-
tact an INFINITI retailer.
•If the battery terminal is disconnected (for
battery replacement, etc.) and then recon-
nected, there may be some delay before
the Stop/Start System reactivates.
BATTERY REPLACEMENT
It is recommended that a Genuine INFINITI
battery is fitted. It is recommended that you
visit an INFINITI retailer for this service.
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 poten-
tially causing serious injury of death.
If the vehicle battery is replaced, the protec-
tive 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 replacement plate. It is recommended
that you visit an INFINITI retailer to purchase
and replace the protective plate underneath
the battery. 1. Make sure the underside of the replace-
ment battery is dry and free of dust.
2. Remove the backing strips
1from the
adhesive strips.
3. Fix the protective plate to the underside of the battery without any overlap

If you have a flat tire, refer to "Flat tire" in the
"6. In case of emergency" section.
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
The Tire Pressure Monitoring System (TPMS)
monitors tire pressure of all tires. When the
low tire pressure warning light is lit, one or
more of the tires is significantly under-
inflated.
The TPMS will activate only when the vehicle
is driven at speeds above 16 MPH (25 km/h).
Also, this system may not detect a sudden
drop in tire pressure (for example a flat tire
while driving).
For additional information, refer to "Tire
Pressure Monitoring System (TPMS)" in the
"5. Starting and driving" section.
Tire inflation pressure
Check the tire pressures (including the spare)
often and always prior to long distance trips.
The recommended tire pressure specifica-
tions are shown on the F.M.V.S.S./
C.M.V.S.S. label or the Tire and Loading In-
formation label (if so equipped) under the
Cold Tire Pressure heading. The Tire and
Loading Information label is affixed to thedriver side center pillar. Tire pressures should
be checked regularly because:
•Most tires naturally lose air over time.
•Tires can lose air suddenly when driven
over potholes or other objects or if the
vehicle strikes a curb while parking.
The tire pressures should be checked when
the tires are cold. The tires are considered
COLD after the vehicle has been parked for 3
or more hours, or driven less than 1 mile (1.6
km) at moderate speeds.
WARNING
•Improperly inflated tires can fail sud-
denly and cause an accident.
•The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S. S./
C.M.V.S.S. certification label. The ve-
hicle weight capacity is indicated on the
Tire and Loading Information label (if so
equipped). Do not load your vehicle be-
yond this capacity. Overloading your
vehicle may result in reduced tire life,
unsafe operating conditions due to pre-
mature tire failure, or unfavorable han-
dling characteristics and could also lead
to a serious accident. Loading beyond
the specified capacity may also result in
failure of other vehicle components.
•Before taking a long trip, or whenever
you heavily load your vehicle, use a tire
pressure gauge to ensure that the tire
pressures are at the specified level.
•For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.

considered COLD after the vehicle has
been parked for 3 or more hours, or driven less than 1 mile (1.6 km) at moder-
ate speeds. The recommended cold tire
inflation is set by the manufacturer to
provide the best balance of tire wear,
vehicle handling, driveability, tire noise,
etc., up to the vehicle’s GVWR.
