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
contains rust and corrosion inhibitors. Addi-
tional engine cooling system additives are not
necessary.
WARNING
●
Never remove the radiator or coolant reser-
voir 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” in the “6.
In case of emergency” section of this
manual.
● The radiator is equipped with a pressure
type radiator cap. To prevent engine dam-
age, use only a genuine NISSAN radiator cap.

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 Main-
tenance Guide for more details.
If the cooling system requires coolant fre-
quently, have it checked by an INFINITI retailer.
CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by an INFINITI retailer. The service pro-
cedures can be found in the appropriate 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 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.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn off the engine. Wait more than 15
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 within the range
1.
If the oil level is below
2, remove the oil
filler cap and pour recommended oil
through the opening. Do not overfill
3.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil mainte-
nance intervals or during the break-in period,
depending on the severity of operating condi-
tions.
CAUTION
Oil level should be checked regularly. Operat-
ing the engine with an insufficient amount of oil
can damage the engine, and such damage is
not covered by warranty.
CHANGING ENGINE OIL AND FILTER
Vehicle set-up
1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn the engine off and wait more than 15 minutes.
4. Raise and support the vehicle using a suitable floor jack and safety jack stands.
●Place the safety jack stands under the
vehicle jack-up points.
● A suitable adapter should be attached to
the jack stand saddle.

FUEL RECOMMENDATION:
VQ35HR engine
INFINITI recommends the use of unleaded pre-
mium gasoline with an octane rating of at least
91 AKI (Anti-Knock Index) number (Research
octane number 96).
If unleaded premium gasoline is not available,
you may use unleaded regular gasoline with an
octane rating of at least 87 AKI number (Re-
search octane number 91), but you may notice a
decrease in performance.
CAUTION
●Using a fuel other than that specified could
adversely affect the emission control sys-
tems, and may also affect warranty
coverage.
● Under no circumstances should a leaded
gasoline be used, since this will damage the
three way catalyst.
● Do not use E-85 fuel in your vehicle. Your
vehicle is not designed to run on E-85 fuel.
Using E-85 fuel can damage the fuel system
components and is not covered by the
INFINITI vehicle limited warranty.
ENGINE OIL RECOMMENDATION:
● Engine oil with API Certification Mark
● Viscosity SAE 5W-30
See “CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS” in the “9. Technical and
consumer information” section for engine oil
and oil filter recommendation.
COLD TIRE PRESSURES:
The label is typically located on the driver side
center pillar or on the driver’s door. For addi-
tional information, see “WHEELS AND TIRES” in
the “8. Maintenance and do-it-yourself” sec-
tion.
NEW VEHICLE BREAK-IN PROCEDURES

During the first 1,200 miles (2,000 km) of
vehicle use, follow the recommendations out-
lined in the “BREAK-IN SCHEDULE” in the “5.
