Allow the belts to dry completely in the shade
before using them. For additional informa-
tion, see "Seat belts" in the "1. Safety — seats,
seat belts and supplemental restraint system"
section.
WARNING
•Do not allow wet seat belts to roll up in
the retractor.
•NEVER use bleach, dye or chemical sol-
vents to clean the seat belts, since these
materials may severely weaken the seat
belt webbing.
CLEANING THE SEAT TRACKS
CAUTION
Periodically clean the seat tracks to pre-
vent reduction of ability to move the seats.
Clean periodically with a high-powered
vacuum cleaner. Dirt and debris may re-
duce the ability to adjust the seat. A wet
cleansing agent may be used if necessary.
GENUINE LEATHER SEAT
COVERS
Automotive leather is typically finished with
coatings which protect the surface from the
sun's damaging rays as well as making it re-
sistant to soiling. The finishes used in auto-
motive upholstery are unique; very different
to furniture, garment or shoe leathers.
Leather is extremely resilient and easy to
clean and maintain.
•Before cleaning leather upholstery,
vacuum it to remove dust.
•To clean leather, simply use a soft and
lint-free cloth dampened with lukewarm
water and mild soap. Do not soak the
leather.
•Use a gentle, circular motion. Do not run
the leather or apply extreme pressure
when cleaning.
•Wipe the leather again with another clean,
slightly damp cloth to remove soap resi-
due. Dry with a soft cloth.
Leather should be cleaned whenever it be-
comes soiled. Dust and dirt may harm leather
if allowed to work into the finish. Never use alcohol, cleaning solvents, oils,
varnishes or polishes on your leather, and
avoid using unknown products as they dam-
age the finish. Only use leather care agents
approved by INFINITI.
Steaming or ironing is not recommended as it
may damage the leather.
Leather is a natural product and has natural
surface properties such as unevenness in
structure, marks caused by injury, and subtle
color differences. These are characteristics of
leather and not material faults.
Leather cleaning kit (if equipped)
Spray onto the leather cleaning cloth, then
gently wipe the surface of leather. Use a dry
towel to absorb any excess moisture.
Please refer to the instruction manual pro-
vided with the leather cleaner kit.
Clean light-colored leather more frequently
because soiling on such surfaces is much
more visible.
You can obtain the leather cleaner kit from an
INFINITI retailer.

MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
Most vehicle corrosion is caused by:
•The accumulation of moisture-retaining
dirt and debris in body panel sections, cavi-
ties, and other areas.
•Damage to the paint surface and other
protective coatings caused by gravel and
stone chips or minor traffic accidents.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
The accumulation of sand, dirt and water on
the inside floor of the vehicle can accelerate
corrosion. Wet floor carpet/floor mats will
not dry completely inside the vehicle. They
should be removed and completely dried 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
and where atmospheric pollution exists and
road salt is used.
Temperature
High temperatures accelerate the rate of cor-
rosion to those parts which are not well ven-
tilated.
Air pollution
Industrial pollution, the presence of salt in the
air in coastal areas, or heavy road salt use
accelerates the corrosion process. Road salt
also accelerates the disintegration 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 surface and repair it as soon as pos-
sible.
•Keep drain holes in the lower edge of the
doors open to avoid water accumulation.
•Check the underbody for accumulation of
sand, dirt or salt. If present, wash with
water as soon as possible.
CAUTION
•NEVER remove dirt, sand or other de-
bris from the passenger compartment
by washing it out with a hose. Remove
dirt with a vacuum cleaner or broom.
•Never allow water or other liquids to
come in contact with electronic compo-
nents inside the vehicle as this may dam-
age them.
Chemicals used for road surface deicing are
extremely corrosive. They accelerate corro-
sion and deterioration of underbody compo-
nents such as the exhaust system, fuel and
brake lines, brake cables, floor pan and fend-
ers.
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 that you visit an
INFINITI retailer.

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self 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 mov-
ing. Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the
engine is hot. Always turn off the engine
and wait until it cools down.
•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 any jewelry, such as
rings, watches, etc. before working 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 by a jack.
•Keep smoking materials, flame and
sparks away from fuel and the battery.
•Never connect or disconnect either the
battery or any transistorized compo-
nent connector while the ignition switch
is in the ON position.
•On gasoline engine models with the
Multiport Fuel Injection system, the fuel
filter and fuel lines should be serviced by
an INFINITI retailer or qualified work-
shop because the fuel lines are under
high pressure even when the engine is
turned off.
•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.
•Always wear eye protection whenever
you work on your vehicle.
•Never leave the engine or the transmis-
sion related component harness connec-
tor disconnected while the ignition
switch is in the ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle
fluids can hurt the environment. Always
conform to local regulations for disposal
of vehicle fluids.
This “ 8. Do-it-yourself” section provides in-
structions regarding only those items which
are relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect your warranty coverage. If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.

WARNING
The engine cooling system is filled at the
factory with a high-quality, year-round,
antifreeze coolant solution. The antifreeze
solution contains rust and corrosion inhibi-
tors, therefore additional cooling system
additives are not necessary.
•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, refer to "If your vehicle
overheats" in the "6. In case of emer-
gency" section
•The engine coolant reservoir tank is
equipped with a pressure type cap. To
prevent engine damage, use only a
genuine INFINITI pressure 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 INFINITI Genuine En-
gine Coolant, BASF Glysantin G40 or
equivalent in its quality. The use of other
types of engine coolant may damage the
engine cooling system.
CHECKING ENGINE COOLANT
LEVEL
NOTE
The coolant level must only be checked and
corrected when the engine is cold.
1. Park the vehicle on a level surface.
Only check the coolant level if the vehicle
is on a level surface and the engine is cold. 2. Slowly turn cap
1half a turn counter-
clockwise to allow excess pressure to es-
cape.
3. Turn cap
1further counter-clockwise
and remove it.
If the coolant is at the level of marker bar
3in the filler neck when cold, there is
enough coolant in coolant expansion tank
2.
4. If necessary, top up with INFINITI Genu- ine Engine Coolant, BASF Glysantin G40
or equivalent in its quality.
5. Replace cap
1and turn it clockwise as
far as it will go.
If the cooling system frequently requires
coolant, have it checked. It is recommended
that you visit an INFINITI retailer for this
service.
CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine
coolant.
Improper servicing can result in reduced
heater performance and engine overheating.
WARNING
•To avoid being scalded, never change
the coolant when the engine is hot.
•Never remove the radiator 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
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
•Keep coolant out of reach of children
and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
