FLOOR MATS The use of Genuine INFINITI floor mats can
extend the life of your vehicle carpet and make
it easier to clean the interior. No matter what
mats are used, be sure they are fitted for
your vehicle and are properly positioned in
the footwell to prevent interference with
pedal operation. Mats should be maintained
with regular cleaning and replaced if they
become excessively worn.
Floor mat positioning aid
(Driver side only) This model includes a front floor mat bracket to
act as a floor mat positioning aid. INFINITI
floor mats have been specially designed for
your vehicle model. The driver's side floor mat
has a grommet hole incorporated in it. Simply
position the mat by placing the floor mat
bracket through the floor mat grommet hole
while centering the mat in the floorpan contour.
Periodically check to make certain that the
mats are properly positioned. SEAT BELTS The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solu-
tion. Allow the belts to dry completely before
using them.
WARNING Do not allow wet belts to roll up in the
retractor. NEVER use bleach, dye, or
chemical solvents since these may se-
verely weaken the seat belt webbing. SAI0012

When performing any inspection or mainte-
nance 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.
WARNINGO Park 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 automatic
transmission, move the selector lever
to P (Park) position.
O Be sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.
O 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.
O It is advised to secure or remove any loose clothing and any jewelry, such
as rings, watches, etc. before work-
ing on your vehicle.
O Always wear eye protection when-
ever you work on your vehicle.
O 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.
O Never 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.
O Keep smoking materials, flame and
sparks away from fuel and the bat-
tery.
O On gasoline engine models with the
Multiport Fuel Injection (MFI) System,
the fuel filter or fuel lines should be
serviced by an INFINITI retailer be-
cause the fuel lines are under high
pressure even when the engine is off. CAUTION O Do not work under the hood while the
engine is hot. Turn off the engine and
wait until it cools down.
O Never connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
O Never leave any engine or automatic
transmission related component har-
ness connector disconnected while
the ignition key is on.
O Avoid 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.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze solu-
tion contains rust and corrosion inhibitors,
therefore additional cooling system additives
are not necessary.
CAUTIONWhen 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
