CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
B, add coolant to the MAX
level
A. 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 reser-
voir up to the MAX level
A. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years.
Mixing any other type of coolant or the use of
non-distilled water will reduce the life expec-
tancy of the factory-fill coolant. For addi-
tional information, refer to the "Maintenance
and schedules" section of this manual.
If the cooling system frequently requires
coolant, have it checked. It is recommended
that you visit an INFINITI retailer for this
service.
For additional information on the location of
the engine coolant reservoir, refer to “Engine
compartment check locations” in this section.
CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine
coolant. The service procedure can be found
in the INFINITI Service Manual.
Improper servicing can result in reduced
heater performance and engine overheating.
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 cool- ant. If skin contact is made, wash thor-
oughly with soap or hand cleaner as soon
as possible.
∙ Keep coolant out of the reach of children and pets.
Engine coolant must be disposed of properly.
Check your local regulations.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than
10 minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way. 5. Remove the dipstick again and check the
oil level. It should be between the H
(High) and L (Low) marksB. This is the
normal operating oil level range. If the oil
level is below the L (Low) mark
A, re-
move the oil filler cap and pour recom-
mended oil through the opening. Do not
fill oil level above H (High) mark
C.
6. Recheck the oil level with the dipstick.
It is normal to add some oil between oil main-
tenance intervals or during the break-in pe-
riod, depending on the severity of operating
conditions.
CAUTION
Oil level should be checked regularly. Oper-
ating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.

plug with a wrench. Do not use excessive
force.
Drain plug tightening torque: 25 ft-lb (34 N·m)
7. Refill engine with recommended oil through the oil filler opening, then install
the oil filler cap securely.
For additional information on drain and
refill capacity, refer to “Recommended
fluids/lubricants and capacities” in the
“Technical and consumer information”
section of this manual.
The drain and refill capacity depends on
the oil temperature and drain time. Use
these specifications for reference only.
Always use the dipstick to determine
when the proper amount of oil is in the
engine.LDI3278

CAUTION
∙ Be sure to remove any old gasket ma-terial remaining on the sealing surface
of the engine. Failure to do so could
lead to an oil leak and engine damage.
∙ The dipstick must be inserted in place to prevent oil spillage from the dipstick
hole when filling the engine with oil.

∙ INFINITI recommends using GenuineNISSAN CVT Fluid NS-3 (or equivalent)
ONLY in INFINITI CVTs. Do not mix with
other fluids.
∙ Do not use Automatic Transmission Fluid (ATF) or manual transmission fluid in an
INFINITI CVT, as it may damage the CVT.
Damage caused by the use of fluids other
than as recommended is not covered un-
der INFINITI’s New Vehicle Limited
Warranty.
∙ Using fluids that are not equivalent to Genuine NISSAN CVT Fluid NS-3 may
also damage the CVT. Damage caused by
the use of fluids other than as recom-
mended is not covered under INFINITI’s
New Vehicle Limited Warranty.
When checking or replacement of CVT fluid is
required, we recommend an INFINITI retailer
for servicing. Check the fluid level in the reservoir.
The fluid level should be checked when the
fluid is cold at fluid temperatures of 32 to
86ºF (0 to 30ºC). The fluid level can be
checked with the level gauge which is at-
tached to the cap. To check the fluid level,
remove the cap. The fluid level should be
between the MAX
Aand MINBlines.
If the fluid is below the MIN
Bline, add
Genuine NISSAN E-PSF or equivalent. Re-
move the cap and fill through the opening.

Some day-to-day and regular maintenance is
essential to maintain your vehicle good me-
chanical condition, as well as its emissions
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
maintenance chain.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal day-
to-day operation. They are essential for
proper vehicle operation. It is your responsi-
bility to perform these procedures regularly
as prescribed.
Performing general maintenance checks re-
quires 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 pre-
fer, an INFINITI retailer.
SCHEDULED MAINTENANCE
The maintenance items listed in this section
are required to be serviced at regular inter-
vals. However under severe driving condi-
tions, additional or more frequent mainte-
nance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the sys-
tems checked and serviced. It is recom-
mended that you visit an INFINITI retailer for
this service.
INFINITI technicians are well-trained spe-
cialists and are kept up-to-date with the lat-
est service information through technical bul-
letins, service tips and training programs.
They are completely qualified to work on
INFINITI vehiclesbeforework begins.
You can be confident that an INFINITI retail-
er’s service department can perform the ser-
vice needed to meet the maintenance re-
quirements on your vehicle. During the normal day-to-day operation of
the vehicle, general maintenance should be
performed regularly as prescribed in this sec-
tion. If you detect any unusual sounds, vibra-
tions or smells, be sure to check for the cause
or have it checked promptly. In addition, it is
recommended that you visit an INFINITI re-
tailer if you think that repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance pre-
cautions” in the “Do-it-yourself” section of
this manual.
