cal solvents to clean the seat belts, since
these materials may severely weaken the
seat belt webbing.

MOST COMMON FACTORS CONTRI-

BUTING TO VEHICLE CORROSION

.

The accumulation of moisture-retaining

dirt and debris in body panel sections,
cavities, and other areas.

.

Damage to paint and other protective

coatings caused by gravel and stone
chips or minor traffic accidents.

ENVIRONMENTAL FACTORS INFLU-

ENCE THE RATE OF CORROSION
Moisture

Accumulation of sand, dirt and water on
the vehicle body underside can accelerate
corrosion. Wet floor coverings will not dry
completely inside the vehicle, and should
be removed for drying to avoid floor panel
corrosion.

Relative humidity

Corrosion will be accelerated in areas of
high relative humidity, especially those
areas where the temperatures stay above
freezing where atmospheric pollution ex-
ists, or where road salt is used.

Temperature

A temperature increase will accelerate the
rate of corrosion to those parts which are
not well ventilated.

Air pollution

Industrial pollution, the presence of salt in
the air in coastal areas, or heavy road salt
use will accelerate the corrosion process.
Road salt will also accelerate the disinte-
gration of paint surfaces.

TO PROTECT YOUR VEHICLE FROM

CORROSION

.

Wash and wax your vehicle often to

keep the vehicle clean.

.

Always check for minor damage to the

paint and repair it as soon as possible.

.

Keep drain holes at the bottom of the

doors open to avoid water accumula-
tion.

.

Check the underbody for accumulation

of sand, dirt or salt. If present, wash
with water as soon as possible.

Appearance and care

CAUTION

.

NEVER remove dirt, sand or other debris
from the passenger compartment by
washing it out with a hose. Remove dirt
with a vacuum cleaner.

.

Never allow water or other liquids to
come in contact with electronic compo-
nents inside the vehicle as this may
damage them.

Chemicals used for road surface deicing
are extremely corrosive. They accelerate
corrosion and deterioration of underbody
components such as the exhaust system,
fuel and brake lines, brake cables, floor
pan and fenders.
In winter, the underbody must be cleaned
periodically.
For additional protection against rust and
corrosion, which may be required in some
areas, it is recommended you consult an
INFINITI retailer.

Do-it-yourself

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage 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
moving. Move the shift lever to P (Park).

.

Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.

.

Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.

.

Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.

.

If you must work with the engine
running, 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 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 fuel tank and the
battery.

.

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.

.

On gasoline engine models, the fuel
filter or fuel lines should be serviced
because the fuel lines are under high

pressure even when the engine is off. It
is recommended you visit an INFINITI
retailer for this service.

CAUTION

.

Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.

.

Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, coolant, and/or other vehicle fluids
can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid.

This “8. Do-it-yourself” section gives in-
structions regarding only those items
which are relatively easy for an owner to
perform.
A genuine INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-32).)
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage. If in

The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/Cool-
ant (blue) and 50% water to provide year-
round anti-freeze and coolant protection.
The antifreeze solution contains rust and
corrosion inhibitors. Additional engine
cooling system additives are not neces-
sary.

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. See precautions in “If your
vehicle overheats” (P.6-11) of this man-
ual.

.

The radiator is equipped with a pressure
type radiator cap. To prevent engine
damage, use only a genuine NISSAN
radiator 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 Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or equiva-
lent. Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is pre-diluted to
provide antifreeze protection to −348F
(−378C). If additional freeze protection is
needed due to weather where you
operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the direc-
tions on the container. If an equivalent
coolant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is used,
follow the coolant manufacturer’s in-
structions to maintain minimum anti-
freeze protection to −348F (−378C). 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
coolant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue), including
Genuine NISSAN Long Life Antifreeze/
Coolant (green), or the use of non-
distilled water will reduce the life ex-
pectancy of the factory-fill coolant. Refer
to the “9. Maintenance and schedules”
section of this manual for more details.
