2003 NISSAN 350Z warning

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
IPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
N (Neutral) position. For an auto-
matic transmission, move the selec-
tor lever to P (Park) position.
IBe sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.
IIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.
IIt is advised to secure or remove any
loose clothing and any jewelry, suchas rings, watches, etc. before work-
ing on your vehicle.
IAlways wear eye protection when-
ever you work on your vehicle.
IIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
INever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel and the bat-
tery.
IOn gasoline engine models with the
Multiport Fuel Injection (MFI) Sys-
tem, the fuel filter or fuel lines should
be serviced by a NISSAN dealer be-
cause the fuel lines are under high
pressure even when the engine is off.
CAUTION
IDo not work under the hood while
the engine is hot. Turn off the engine
and wait until it cools down.
INever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion key is on.
INever leave the engine or the auto-
matic transmission related compo-
nent harness connector discon-
nected while the ignition key is on.
IAvoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid.
This ª8. Maintenance and do-it-yourselfº section

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze cool-
ant solution. The anti-freeze solution contains
rust and corrosion inhibitors, therefore additional
cooling system additives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only a genuine NISSAN
anti-freeze coolant or equivalent with
the proper mixture ratio of 50% anti-
freeze and 50% demineralized
water/distilled water. The use of other
types of coolant solutions may damage
your engine cooling system.Outside temperature

CHECKING ENGINE COOLANT
LEVELCheck the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below MIN, add coolant up to the MAX level. If
the reservoir tank is empty, check the coolant
level in the radiatorwhen 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 reservoir tank up to the MAX
level.
If the engine cooling system frequently
requires coolant, have it checked by your
NISSAN dealer.
