Infiniti Jx35 (2013 year). Manual — part 30

Your INFINITI has been designed to have mini-
mum maintenance requirements with long ser-
vice intervals to save you both time and money.
However, some day-to-day and regular mainte-
nance is essential to maintain your INFINITI’s
good mechanical condition, as well as its emis-
sions 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 proper
maintenance. You are a vital link in the mainte-
nance chain.

Scheduled maintenance

For 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
INFINITI at regular intervals.

General maintenance

General maintenance includes those items which
should be checked during normal day-to-day op-
eration. They are essential for proper vehicle op-
eration. It is your responsibility to perform these
maintenance procedures regularly 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 you,
a qualified technician, or, if you prefer, an INFINITI
retailer.

Where to go for service

If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and corrected by an INFINITI retailer.

INFINITI technicians are well-trained specialists
who are kept up-to-date with the latest service
information through technical bulletins, service
tips, and in-retailer training programs. They are
completely qualified to work on INFINITI vehicles
before they work on your vehicle, rather than
after they have worked on it.

You can be confident that an INFINITI retailer’s
service department performs the best job to meet
the maintenance requirements on your vehicle —
in a reliable and economical way.

During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smells, 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 maintenance
work, closely observe the “Maintenance precau-
tions” later in this section.

EXPLANATION OF GENERAL
MAINTENANCE ITEMS

Additional information on the following
items with “ * ” is found later in this section.

Outside the vehicle

The maintenance items listed here should be
performed from time to time, unless otherwise
specified.

Doors and engine hood Check that the doors
and engine hood operate properly. Also ensure
that all latches lock securely. Lubricate hinges,
latches, latch pins, rollers and links as necessary.
Make sure that the secondary latch keeps the
hood from opening when the primary latch is
released.

MAINTENANCE REQUIREMENTS

GENERAL MAINTENANCE

8-2

Maintenance and do-it-yourself

When driving in areas using road salt or other
corrosive materials, check lubrication frequently.

Lights* Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.

Road wheel nuts (lug nuts)* When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.

Tire rotation* Tires should be rotated every
7,500 miles (12,000 km).

Tires* Check the pressure with a gauge often
and always prior to long distance trips. If neces-
sary, adjust the pressure in all tires, including the
spare, to the pressure specified. Check carefully
for damage, cuts or excessive wear.

Tire Pressure Monitoring System (TPMS)
transmitter components Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.

Wheel alignment and balance If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven or
abnormal tire wear, there may be a need for wheel

alignment. If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing may be
needed.

● For additional information regarding tires,

refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.

Windshield Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility.

Windshield wiper blades* Check for cracks or
wear if they do not wipe properly.

Inside the vehicle

The maintenance items listed here should be
checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the ve-
hicle, etc.

Additional information on the following
items with an “*” is found later in this sec-
tion.

Accelerator pedal Check the pedal for smooth
operation and make sure the pedal does not bind
or require uneven effort. Keep the floor mat away
from the pedal.

Brake pedal Check the pedal for smooth opera-
tion. If the brake pedal suddenly goes down fur-
ther than normal, the pedal feels spongy or the
vehicle seems to take longer to stop, see an
INFINITI retailer immediately. Keep the floor mat
away from the pedal.

Brakes Check that the brakes do not pull the
vehicle to one side when applied.

Continuously Variable Transmission (CVT)
P (Park) position mechanism On a fairly
steep hill check that your vehicle is held securely
with the shift selector in the P (Park) position
without applying any brakes.

Parking brake Check the parking brake opera-
tion regularly. The vehicle should be securely held
on a fairly steep hill with only the parking brake
applied. If the parking brake needs adjustment,
see an INFINITI retailer.

Seats Check seat position controls such as seat
adjusters, seatback recliner, etc. to ensure they
operate smoothly and all latches lock securely in
every position. Check that the head restraints and
headrests move up and down smoothly and the
locks (if so equipped) hold securely in all latched
positions.

Seat belts Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,

and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.

Steering wheel Check for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.

Warning lights and chimes Make sure all
warning lights and chimes are operating properly.

Windshield wiper and washer* Check that
the wipers and washer operate properly and that
the wipers do not streak.

Windshield defroster Check that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.

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* Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions 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. In-
stallation 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 dis-
tances. 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 MIN and MAX lines on the
reservoir.

Engine coolant level* Check the coolant level
when the engine is cold.

Engine drive belts* Make sure the drive belts
are not frayed, worn, cracked or oily.

Engine oil level* Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.

Exhaust system Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by an INFINITI retailer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.

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 if gasoline fumes are evident, check for
the cause and have it corrected immediately.

Power steering fluid level* and lines Check
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.

Radiator and hoses Check 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, rot or loose
connections.

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 from the underbody, oth-
erwise rust may form on the floor pan, frame, fuel
lines and exhaust system. At the end of winter, the
underbody should be thoroughly flushed with plain
water, in those areas where mud and dirt may have
accumulated. See the “Appearance and care” sec-
tion of this manual.

Windshield-washer fluid* Check that there is
adequate fluid in the reservoir.

8-4

Maintenance and do-it-yourself

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.

WARNING

● Park the vehicle on a level surface, ap-

ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the shift selector to
P (Park).

● Be sure the ignition switch is in the OFF

or LOCK position when performing any
parts replacement or repairs.

● 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 remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.

● Always wear eye protection whenever

you work on your vehicle.

● 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 posi-
tion and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before working
near the fan.

● If you must run the engine in an en-

closed 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 neces-
sary to work under the vehicle, support
it with safety stands.

● Keep smoking materials, flame and

sparks away from the fuel tank and
battery.

● 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 contact with used engine oil and

coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.

● Never leave the engine or continuously

variable transmission related compo-
nent harnesses disconnected while the
ignition switch is in the ON position.

● Never connect or disconnect the battery

or any transistorized component while
the ignition switch is in the ON position.

This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.

You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage. If in doubt about any servicing,
have it done by an INFINITI retailer.

Maintenance and do-it-yourself

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round anti-freeze and
coolant protection. The antifreeze solution con-
tains rust and corrosion inhibitors. Additional en-
gine cooling system additives are not necessary.

WARNING

● Never remove the radiator or coolant

reservoir 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. See precautions in “If your
vehicle overheats” found in the “In case
of emergency” section of this manual.

● The radiator is equipped with a pres-

sure type radiator cap. To prevent en-
gine 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

equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to -34°
F (-37° C). If additional freeze protec-
tion 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 manufacturer’s
instructions to maintain minimum anti-
freeze protection to -34° F (-37° C). The
use of other types of coolant solutions
other than Genuine NISSAN Long Life
Antifreeze/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 cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue), includ-
ing

Genuine

NISSAN

Long

Life

Antifreeze/Coolant (green), or the use
of non-distilled water will reduce the
life expectancy of the factory-fill cool-
ant. Refer to the Nissan Service and
Maintenance Guide for more details.

CHECKING ENGINE COOLANT
LEVEL

Check the coolant level in the reservoir when
the engine is cold. If the coolant level is below
the MIN level, add coolant to the MAX level. If the
reservoir is empty, check the coolant level in the
radiator when the engine is cold. If there is
insufficient coolant in the radiator, fill the radiator
with coolant up to the filler opening and also add
it to the reservoir up to the MAX level.

This vehicle contains Genuine NISSAN Long Life
Antifreeze/Coolant (blue). The life expectancy of
the factory-fill coolant is 168,000 km (105,000
mi) or 7 years. Mixing any other type of coolant or

the use of non-distilled water will reduce the life
expectancy of the factory-fill coolant. Refer to the
INFINITI Service and Maintenance Guide for
more details.

The engine coolant reservoir is a pressur-
ized tank. When installing the cap, tighten
it until a clicking sound is heard.

If the cooling system frequently requires
coolant, have it checked by an INFINITI
retailer.

CHANGING ENGINE COOLANT

An INFINITI retailer can change the engine cool-
ant. The service procedure can be found in the
INFINITI Service Manual.

Improper servicing can result in reduced
heater performance and engine overheat-
ing.

WARNING

● To avoid the danger of being scalded,

never change the coolant when the en-
gine is hot.

● Never remove the radiator or engine

coolant reservoir cap when the engine
is hot. Serious burns could be caused
by high pressure fluid escaping from
the radiator.

● Avoid direct skin contact with used

coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.

● Keep coolant out of the reach of chil-

dren and pets.

Engine coolant must be disposed of properly.
Check your local regulations.

● 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 to be 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:

1. Installation or extended use of electronic

accessories that consume battery power
when the engine is not running (Phone char-
gers, 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.

WARNING

● Do not expose the battery to flames, an

electrical spark or a cigarette. Hydro-
gen gas generated by the battery is ex-
plosive. Explosive gases can cause
blindness or injury. Do not allow battery
fluid to contact your skin, eyes, fabrics
or painted surfaces. Sulfuric acid can
cause blindness or injury. After touch-
ing a battery or battery cap, do not

wash your hands. If the acid contacts
your eyes, skin or clothing, immediately
flush with water 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 generate heat, reduce bat-
tery life, and in some cases lead to an
explosion.

● When working on or near a battery, al-

ways wear suitable eye protection and
remove all jewelry.

● Battery posts, terminals and related ac-

cessories contain lead and lead com-
pounds. Wash hands after handling.
