When performing any inspection or maintenance
work on your vehicle, always take care to pre-
vent serious accidental injury to yourself or dam-
age to the vehicle. The following are general
precautions which should be closely observed.
WARNING
• Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Push the park button to engage the
P (Park) position.
• Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
• If you must work with the engine run-
ning, keep your hands, clothing, hair and
tools away from moving fans, belts and
any other moving parts.
• It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before work-
ing on your vehicle.
• Always wear eye protection whenever
you work on your vehicle.
• Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position and the engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
• If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
• Never get under the vehicle while it is
supported only by a jack. If it is necessary
to work under the vehicle, support it
with safety stands.
•
Keep smoking materials, flame and sparks
away from the fuel tank and battery.
• Because the fuel lines on gasoline engine
models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
CAUTION
• Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
• Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle flu-
ids can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid. •
Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
• Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
This “Do-it-yourself” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine INFINITI service manual is also
available. For additional information, see
“Owner’s Manual/Service Manual order in-
formation” (P. 10-36).
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect warranty coverage. If in doubt about any
servicing, it is recommended that you have it
done by an INFINITI retailer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

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 antifreeze and coolant protec-
tion. The antifreeze solution contains rust
and corrosion inhibitors. Additional engine
cooling system additives are not necessary.
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. For additional information on
precautions, see “If your vehicle over-
heats” (P. 6-14).
• The radiator is equipped with a pressure
type radiator cap. To prevent engine
damage, use only a Genuine NISSAN ra-
diator cap.
CAUTION
• Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age 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
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to -34°
F (-37° C). If additional freeze protection
is needed due to weather where you op-
erate your vehicle, add Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
concentrate following the directions on
the container. If an equivalent coolant
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s instruc-
tions to maintain minimum antifreeze
protection to -34° F (-37° C). 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 cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) (or
equivalent coolant), including Genuine
NISSAN Long Life Antifreeze/Coolant
(green), or the use of non-distilled water
may reduce the life expectancy of the
factory-fill coolant. For additional infor-
mation, see the “Maintenance and
schedules” section of this manual.
ENGINE COOLING SYSTEM
8-4Do-it-yourself

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
OB, add coolant to the MAX
level
OA. 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
OA. 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, see the "Maintenance and sched-
ules" 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, see “Engine
compartment check locations” (P. 8-3).
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.

9-6Maintenance and schedules

Remember to keep trailer tongue weight be-
tween 10 - 15% of the trailer weight or within
the trailer tongue load specification recom-
mended by the trailer manufacturer. If the
tongue load becomes excessive, rearrange
the cargo to obtain the proper tongue load.
Do not exceed the maximum tongue weight
specification shown in the “Towing Load/
Specification” chart even if the calculated
available tongue weight is greater than 15%.
If the calculated tongue weight is less than
10%, reduce the total trailer weight to match
the available tongue weight.
Always verify that available capacities are
within the required ratings.TOWING LOAD/SPECIFICATION
WARNING
The towing capacities provided in this
manual are for general reference only. The
safe towing capacity of your vehicle is af-
fected by dealer and factory installed op-
tions and passenger and cargo loads. You
must weigh the vehicle and trailer as de-
scribed in this manual to determine the ac-
tual vehicle towing capacity. Do not exceed
the published maximum towing capacity or
the GCWR or the GVWR shown on the
FMVSS/CMVSS label. Doing so can result
in an accident causing serious personal in-
jury or property damage.
