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 that is not
equivalent to Genuine NISSAN Long Life
Antifreeze/Coolant (blue), or the use of non-
distilled water will reduce the life expectancy
of the factory-fill coolant. For additional in-
formation, 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.
CHANGING ENGINE OIL AND OIL
FILTER

CAUTION
Be sure to remove any old gasket material
remaining on the sealing surface of the en-
gine. 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.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten ad-
ditionally more than 2/3 turn.
Oil filter tightening torque: 11 to 15 ft-lb (15.0 to 21.0 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten the drain
plug with a wrench. Do not use excessive
force.
Drain plug tightening torque: 22 to 29 ft-lb (29.4 to 39.2 N·m)
9. Refill the engine with the recommended oil through the oil filler opening, and in-
stall the oil filler cap securely.
For additional information about drain and
refill capacity, refer to “Recommended
fluids/lubricants and capacities” in the “Tech-
nical and consumer information” section of
this manual. The drain and refill capacity de-
pends on the oil temperature and drain time.
Use these specifications for reference only. Always use the dipstick to determine the
proper amount of oil in the engine.
10. Start the engine and check for leakage
around the drain plug and the oil filter.
Correct as required. Turn the engine off
and wait more than 15 minutes. Check
the oil level with the dipstick. Add engine
oil if necessary.
After the operation
1. Reinstall engine protectors in reverse or-der of removal.
2. Lower the vehicle carefully to the ground.
3. Reset oil and oil filter maintenance re- minder. For additional information, refer
