8-2Maintenance and do-it-yourself
Y51D-V-E01-99388A75-FA9F-4C12-87AA-7212C765E30CSome day-to-day and regular maintenance
is essential to maintain your vehicle’s good
mechanical condition, as well as its emis-
sion and engine performance.
It is the owner’s responsibility to make
sure that the scheduled maintenance, as
well as general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
the proper maintenance. You are a vital link
in the maintenance chain.
SCHEDULED MAINTENANCEY51D-V-E01-4AB86854-3F44-433C-8B66-59A89D3B0CB5For your convenience, both required and
optional scheduled maintenance items are
described and listed in your“INFINITI
Service and Maintenance Guide”. You must
refer to that guide to ensure that necessary
maintenance is performed on your vehicle
at regular intervals.
GENERAL MAINTENANCEY51D-V-E01-9C899EFE-CF7B-44F1-9A3D-78EF760B05BDGeneral maintenance includes those items
which should be checked during normal
day-to-day operation. They are essential for
proper vehicle operation. It is your respon-
sibility to perform these procedures reg-
ularly as prescribed.
Performing general maintenance checks requires minimal mechanical skill and only
a few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, an INFINITI retailer.
WHERE TO GO FOR SERVICEY51D-V-E01-340061AC-7165-4FC2-8430-EDF309D4BC76If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and serviced by an
INFINITI retailer.
INFINITI technicians are well-trained spe-
cialists and are kept up to date with the
latest service information through techni-
cal bulletins, service tips, and in-retailer-
ship information systems. They are
completely qualified to work on INFINITI
vehicles
beforework begins.
You can be confident that an INFINITI
retailer’s service department performs the
best job to meet the maintenance require-
ments on your vehicle.
Y51D-V-E01-1FE91147-D03A-454F-8CE2-41718682DE9EDuring the normal day-to-day operation of
the vehicle, general maintenance should
be performed regularly as prescribed in
this section. If you detect any unusual
sounds, vibrations or smell, be sure to
check for the cause or have an INFINITI
retailer do it promptly. In addition, you
should notify an INFINITI retailer if you
think that repairs are required.
When performing any checks or mainte-
nance work, see “Maintenance precau-
tions” (P.8-5).

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
substances, 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 may
accumulate. For additional information,
see “Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir.
Y51D-V-E01-239C92D7-82C6-4E8E-B4CA-4F36484B9DCBWhen performing any inspection or main-
tenance 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.
WARNING
. Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from
moving. Move the shift lever to P (Park).
. Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
. Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
. 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 remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
. Always wear eye protection whenever
you work 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 only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key 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.
. The fuel filter or fuel lines should be
serviced by an INFINITI retailer because
the fuel lines are under high pressure

even when the engine is off.
CAUTION
.Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
. Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, coolant, and/or other vehicle fluids
can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid.
This “8. Maintenance and do-it-yourself”
section gives instructions regarding only
those items which are relatively easy for an
owner to perform.
A genuine INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.9-23).)
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage. If in
doubt about any servicing, we recommend
that it be done by an INFINITI retailer.

Y51D-V-E01-662E477D-FA0C-4DA9-8B55-B58B05C7E362The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/Cool-
ant (blue) and 50% water to provide year-
round anti-freeze and coolant protection.
The anti-freeze solution contains rust and
corrosion inhibitors. Additional engine
cooling system additives are not neces-
sary.
WARNING
.Never remove the radiator cap when the
engine is hot. Wait until the engine and
radiator cool down. Serious burns could
be caused by high pressure fluid escap-
ing from the radiator. See precautions in
“If your vehicle overheats” (P.6-12).
. The radiator is equipped with a pressure
type radiator cap. To prevent engine
damage, use only a genuine NISSAN
radiator 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.
. When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or equiva-
lent. Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is pre-diluted to
provide antifreeze protection to −348F
(−378C). If additional freeze protection is
needed due to weather where you
operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the direc-
tions on the container. If an equivalent
coolant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is used,
follow the coolant manufacture’s instruc-
tions to maintain minimum antifreeze
protection to −348F (−378C). The use of
other types of coolant solutions other
than Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) or equivalent may
damage the engine cooling system.
. The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km)
or 7 years. Mixing any other type of
coolant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) , including
Genuine NISSAN Long Life Antifreeze/ Coolant (green), or the use of non-
distilled water will reduce the life
expectancy of the factory-fill coolant.
Refer to the INFINITI Service and Main-
tenance Guide for more details.

return to normal.
BRAKE PAD WEAR WARNINGY51D-V-E01-D89227A8-C2EA-43BF-8410-9B39CA613024The disc brake pads have audible wear
warnings. When a brake pad requires
replacement, it will make a high pitched
scraping sound when the vehicle is in
motion. This scraping sound will first occur
only when the brake pedal is depressed.
After more wear of the brake pad, the
sound will always be heard even if the
brake pedal is not depressed. Have the
brakes checked as soon as possible if the
wear warning sound is heard.
Under some driving or climate conditions, occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is
normal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.

Wheel balanceY51D-V-E01-D5C0F0AD-B802-4348-80B3-530384ED22ADUnbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance. There-
fore, they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
For additional information regarding tires,
refer to“Important Tire Safety Information”

about care of the wheels.
Spare tire (TEMPORARY USE ONLY
(T-type) spare tire)
Y51D-V-E01-BBC25E52-7616-48C3-B40B-A17EDC437007Observe the following precautions if the T-
type spare tire must be used, otherwise
your vehicle could be damaged or involved in an accident.
WARNING
.
The T-type spare tire should be used for
emergency use. It should be replaced
with the standard tire at the first
opportunity to avoid possible tire or
differential damage.
. Drive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
. Periodically check spare tire inflation
pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire at
60 psi (420 kPa, 4.2 bar). Always keep
the pressure of the full size spare tire (if
so equipped) at the recommended pres-
sure for standard tires, as indicated on
the Tire and Loading Information label.
For Tire and Loading Information label
location, see “Tire and loading informa-
tion label” (P.9-13).
. With the TEMPORARY USE ONLY spare
tire installed do not drive your vehicle at
speeds faster than 50 MPH (80 km/h). .
When driving on roads covered with
snow or ice, the TEMPORARY USE ONLY
spare tire should be used on the front
wheels and original tire used on the rear
wheels (drive wheels). Use tire chains
only on the two rear original tires.
. Tire tread of the TEMPORARY USE ONLY
spare tire will wear at a faster rate than
the standard tire. Replace the spare tire
as soon as the tread wear indicators
appear.
. Do not use the spare tire on other
vehicles.
. Do not use more than one spare tire at
the same time.
CAUTION
.Do not use tire chains on a TEMPORARY
USE ONLY spare tire. Tire chains will not
fit properly and may cause damage to
the vehicle.
. Because the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also do not drive
