WARNING
The engine cooling system is filled at the fac-
tory with a high-quality, year-round, antifreeze
coolant solution. The antifreeze solution con-
tains rust and corrosion inhibitors, therefore
additional cooling system additives are not
necessary.
•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. For addi-
tional information on precautions, refer to
If your vehicle overheatsin the6. In case
of emergencysection
•The engine coolant reservoir tank is
equipped with a pressure type cap. To pre-
vent engine damage, use only a genuine
INFINITI pressure 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 INFINITI Genuine Engine Cool-
ant, BASF Glysantin G40 or equivalent in its
quality. The use of other types of engine
coolant may damage the engine cooling
system.
CHECKING ENGINE COOLANT LEVEL
NOTE
The coolant level must only be checked and cor-
rected when the engine is cold.
1. Park the vehicle on a level surface.
Only check the coolant level if the vehicle is
on a level surface and the engine is cold.
2. Slowly turn cap
1half a turn counter-
clockwise to allow excess pressure to es-
cape.
3. Turn cap
1further counter-clockwise and
remove it.
If the coolant is at the level of marker bar
3in the filler neck when cold, there is enough
coolant in coolant expansion tank
2.4. If necessary, top up with INFINITI Genuine
Engine Coolant, BASF Glysantin G40 or
equivalent in its quality.
5. Replace cap
1and turn it clockwise as far
as it will go.
If the cooling system frequently requires cool-
ant, have it checked. It is recommended that you
visit an INFINITI retailer for this service.

CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine cool-
ant.
Improper servicing can result in reduced heater
performance and engine overheating.
WARNING
•To avoid 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 pos-
sible.
•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. Start the engine and let it idle until it
reaches the normal 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
1and wipe it clean.
Reinsert it all the way.
5. Remove the dipstick and check the oil level.
It should be within the range
2and3.
If the oil level is below
3, remove the oil
filler cap and pour the recommended oil into
the opening.Do not overfill
2.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
The oil level should be checked regularly. Op-
erating the engine with an insufficient amount
of oil can damage the engine, and such dam-
age is not covered by the warranty.
CHANGING ENGINE OIL
WARNING
•Prolonged and repeated contact with used
engine oil may cause skin cancer.
•Try to avoid direct skin contact with used
oil. If skin contact is made, wash thoroughly
with soap or hand cleaner and plenty of wa-
ter as soon as possible.
•Keep used engine oil out of reach of
children.
CAUTION
Be careful not to burn yourself. The engine oil
may be hot.

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 in-
spected. It is recommended you visit an INFINITI
retailer for this service. SeePrecautions when
starting and drivingin the5. Starting and
drivingsection.
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 evi-
dent, check for the cause and have it corrected
immediately.
Radiator and hoses
:
Check the front of the radiator and clean off any
dirt, insects, leaves, etc., that may have accu-
mulated. Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody
:
The underbody is frequently exposed to corro-
sive substances such as those used on icy
roads or to control dust. It is very important to
remove these substances, otherwise rust willform on the floor pan, frame, fuel lines and
around the exhaust system. At the end of
winter, the underbody should be thoroughly
flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. For additional information, seeCleaning
exteriorin the7. Appearance and caresec-
tion.
Windshield washer fluid*
:
Check that there is adequate fluid in the reser-
voir.The following descriptions are provided to give
you a better understanding of the scheduled
maintenance items that should be regularly
checked or replaced. The maintenance schedule
indicates at which mileage/time intervals each
item requires service.
In addition to scheduled maintenance, your
vehicle requires that some items be checked
during normal day-to-day operation. Refer to
General maintenancein this section.
Items marked with “*” are recommended by
INFINITI for reliable vehicle operation. You are
not required to perform maintenance on these
items in order to maintain the warranties which
come with your vehicle. Other maintenance
items and intervals are required.
When applicable, additional information can be
found in the “Do-it-yourself” section in Chapter
8.
NOTE
INFINITI does not advocate the use of non-OEM
approved aftermarket flushing systems and
strongly advises against performing these ser-
vices on an INFINITI product. Many of the after-
market flushing systems use non-OEM approved
chemicals or solvents, the use of which has not
been validated by INFINITI.
