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
lever to P (Park).
●
Be sure the ignition key is in the OFF or
LOCK position when performing any
parts replacement or repairs.
●
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.
●
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key 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 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.
●
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 with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by an INFINITI 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.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
A genuine INFINITI service manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “Technical and consumer
information” section of this manual.
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 an INFINITI dealer.
