warning NISSAN MAXIMA 2012 A35 / 7.G Owners Manual

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
●Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the shift selector to
P (Park) .
● 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
working 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 posi-
tion 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 en-
closed 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 neces-
sary to work under the vehicle, support
it with safety stands.
● Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
● On gasoline engine models, the fuel
filter or fuel lines should be serviced by
a NISSAN dealer because the fuel lines
are under high pressure even when the
engine is off.
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
fluids can damage the environment. Al-
ways 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.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage. If in doubt about any servicing,
have it done by a NISSAN dealer.

ENGINE COOLING SYSTEM
Maintenance and do-it-yourself8-7

This vehicle contains Genuine NISSAN Long Life
Antifreeze/Coolant (blue) . The life expectancy 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
expectancy of the factory-fill coolant. Refer to the
NISSAN Service and Maintenance Guide for
more details.
If the cooling system frequently requires
coolant, have it checked by a NISSAN
dealer.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine coolant.
The service procedure can be found in the
