TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
GUID-EFDE8E6D-AFA0-4243-A90D-0D01CCEE6814This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears on the dot
matrix liquid crystal display, one or more
of your tires is significantly under-inflated.
If the vehicle is being driven with low tire
pressure, the TPMS will activate and warn
you of it by the low tire pressure warning
light. This system will activate only when
the vehicle is driven at speeds above 16
MPH (25 km/h). For more details, see
“Warning/indicator lights and audible re-
minders” (P.2-12) and “Tire Pressure Mon-
itoring System (TPMS)” (P.5-4).
WARNING
.If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road to
a safe location and stop the vehicle as
soon as possible. Driving with under-
inflated tires may permanently damage

seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan
is running. The radiator hoses and
radiator should not leak water. If cool-
ant is leaking or the cooling fan does not run, stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.
7. After the engine cools down, check the
coolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired at the nearest INFINITI
retailer.

GUID-7909F151-D270-426B-9317-ECCCF136345AYour new INFINITI has been designed to
have minimum maintenance requirements
with long service intervals to save you both
time and money. However, some day-to-
day and regular maintenance is essential
to maintain your INFINITI’s fine mechanical
condition, as well as its emission 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 care. You are a
vital link in the maintenance chain.
SCHEDULED MAINTENANCEGUID-F67C0E74-FE81-4021-BFE9-6DCAA8B62868For 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 MAINTENANCEGUID-F5FB4C7E-7009-4482-8936-6B69512CBAEFGeneral 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 SERVICEGUID-36AD273A-936D-4E75-BA34-F3522084B4D1If 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
—in a reliable and
economical way.
Maintenance and do-it-yourself8-3
MAINTENANCE REQUIREMENT

Black plate (413,1)
[ Edit: 2012/ 1/ 17 Model: V36-D ]
.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.9-28).)
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.

GUID-5C044D87-071E-4DD5-85C9-155F3106646BThe 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 antifreeze solution contains rust and
corrosion inhibitors. Additional engine
cooling system additives are not neces-
sary.
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” (P.6-10) of this man-
ual.
. 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 manufacturer’s in-
structions to maintain minimum anti-
freeze protection to −348F (−378C). 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
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.

CHECKING ENGINE COOLANT LEVELGUID-0A58561D-6ED8-4332-9DEB-68F0F2BD40A6Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below MIN
*2, open the reservoir
tank cap and add coolant up to the MAX
*1
level. If the reservoir tank 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 tank up to the
MAX level
*1.
Tighten the cap securely after adding
engine coolant. If the cooling system requires coolant
frequently, have it checked by an INFINITI
retailer.
CHANGING ENGINE COOLANTGUID-5414AC03-7904-49CD-BD61-168CF59A9756Major cooling system repairs should be
performed by an INFINITI retailer. The
service procedures can be found in the
appropriate 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
engine is hot.
. Never remove the radiator 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 reach of children and
pets.
Engine coolant must be disposed of
properly. Check your local regulations.

SELF-ADJUSTING BRAKESGUID-2D98160D-8918-4BF3-999B-F13E2922E177Your vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every time
the brake pedal is applied.
WARNING
See an INFINITI retailer for a brake system
check if the brake pedal height does not
return to normal.
BRAKE PAD WEAR WARNINGGUID-0D7DECB1-F0F3-4C66-A768-32FE17341FFFThe 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.
For additional information,
see the maintenance log section of your
“INFINITI Service and Maintenance Guide”
for maintenance intervals.
