●Properly position the mats in the floor-
well using the floor mat positioning
hook. For additional information, refer
to Floor mat installation in this
section.
● Make sure the floor mat does not inter-
fere with pedal operation.
● Periodically check the floor mats to
make sure they are properly installed.
● After cleaning the vehicle interior,
check the floor mats to make sure they
are properly installed.
The use of Genuine INFINITI floor mats can ex-
tend the life of your vehicle carpet and make it
easier to clean the interior. Mats should be main-
tained with regular cleaning and replaced if they
become excessively worn.
Floor mat installation
Your vehicle is equipped with floor mat position-
ing hook(s) . The number and shape of the floor
mat positioning hooks for each seating position
varies depending on the vehicle. When installing Genuine INFINITI floor mats, fol-
low the installation instructions provided with the
mat and the following:
1. Position the floor mat in the floorwell so that the floor mat grommet holes are aligned with
the hook(s) .
2. Secure the grommet holes into the hook(s) and ensure that the floor mat is properly
positioned.
3. Make sure the floor mat does not interfere with pedal operation. With the ignition in the
OFF position, the shift lever in the P (Park)
position (Automatic Transmission models)
or the shift lever in the N (Neutral) position
(Manual Transmission models) fully apply
and release all pedals. The floor mat must
not interfere with pedal operation or prevent
the pedal from returning to its normal posi-
tion.
It is recommended that you visit an INFINITI re-
tailer for details about installing the floor mats in
your vehicle. The illustration shows the location of the floor mat
positioning hooks.
SEAT BELTS
The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solution.
Allow the belts to dry completely in the shade
before using them. For additional information,
refer to “Seat belt maintenance” in the “Safety-
–Seats, seat belts and supplemental restraint
system” section of this manual.

WARNING
Do not allow wet seat belts to roll up in the
retractor. NEVER use bleach, dye or
chemical solvents 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 reduce the ability to
adjust the seat. A wet cleansing agent may be
used if necessary.
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, cavities,
and other areas.
● Damage to paint and other protective coat-
ings caused by gravel and stone chips or
minor traffic collisions.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on the ve-
hicle 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 and where
atmospheric pollution exists and road salt is
used.
Temperature
High temperatures accelerate the rate of corro-
sion 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 acceler-
ates the corrosion process. Road salt also accel-
erates the disintegration of paint surfaces.
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 accumulation.
● Check the underbody for accumulation of
sand, dirt or salt. If present, wash with water
as soon as possible.
CORROSION PROTECTION
Appearance and care7-7
Page 555 of 655
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
damage them.
Chemicals used for road surface de-icing 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 corro-
sion, which may be required in some areas, it is
recommended that you consult an INFINITI re-
tailer.

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 lever 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.
●Because the fuel lines on gasoline engine
models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
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 Continuously
Variable Transmission (CVT) related
component harnesses 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.

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round antifreeze and
coolant protection. The antifreeze solution con-
tains rust and corrosion inhibitors. Additional en-
gine cooling system additives are not necessary.
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. For additional information
on precautions, refer to “If your vehicle
overheats” found in the “In case of
emergency” section of this manual.
● The radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine 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 dam-
age 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
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to -34°
F (-37° C) . 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
instructions to maintain minimum anti-
freeze protection to -34° F (-37° C) . 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 cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) , includ-
ing Genuine NISSAN Long Life
Antifreeze/Coolant (green) , or the use
of non-distilled water will reduce the
life expectancy of the factory-fill cool-
ant. For additional information, refer to
the Maintenance and schedules section
of this manual.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
B, add coolant to the MAX level
A. If the reservoir is empty, check the coolant
level in the radiator when 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 up to the MAX level
A. 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 re-
duce the life expectancy of the factory-fill coolant.
For additional information, refer to the
Mainte-
nance and schedules section of this manual.
If the cooling system frequently requires
coolant, have it checked. It is recom-
mended that you visit an INFINITI retailer
for this service.
For additional information on the location of the
engine coolant reservoir, refer to “Engine com-
partment check locations” in this section.
CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine cool-
ant. The service procedure can be found in the
INFINITI Service Manual. Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
●
To avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
● Never remove the radiator or engine
coolant reservoir 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 the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
