ambient temperature.
. Rinse the wheel to completely remove
the cleaner within 15 minutes after the
cleaner is applied.
CHROME PARTS
Clean chrome parts regularly with a non-
abrasive chrome polish to maintain the
finish.
TIRE DRESSING
INFINITI does not recommend the use of
tire dressings. Tire manufacturers apply a
coating to the tires to help reduce dis-
coloration of the rubber. If a tire dressing is
applied to the tires, it may react with the
coating and form a compound. This com-
pound may come off the tire while driving
and stain the vehicle paint.
If you choose to use a tire dressing, take
the following precautions:
.Use a water-based tire dressing. The
coating on the tire dissolves more
easily with an oil-based tire dressing.
. Apply a light coat of tire dressing to
help prevent it from entering the tire
tread/grooves (where it would be diffi-
cult to remove). .
Wipe off excess tire dressing using a
dry towel. Make sure the tire dressing
is completely removed from the tire
tread/grooves.
. Allow the tire dressing to dry as
recommended by tire dressing manu-
facturer. Occasionally remove loose dust from the
interior trim, plastic parts and seats using
a vacuum cleaner or soft bristled brush.
Wipe the vinyl and leather surfaces with a
clean, soft cloth dampened in mild soap
solution, then wipe clean with a dry soft
cloth.
Regular care and cleaning is required in
order to maintain the appearance of the
leather.
Before using any fabric protector, read the
manufacturer’
s recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water, to
clean the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classification
sensors. This can also affect the operation
of the air bag system and result in serious
personal injury.
CLEANING INTERIOR

CAUTION
.Never use benzine, thinner, or any
similar material.
. Small dirt particles can be abrasive and
damaging to the leather surfaces and
should be removed promptly. Do not use
saddle soap, car waxes, polishes, oils,
cleaning fluids, solvents, detergents or
ammonia-based cleaners as they may
damage the leather’s natural finish.
. Only use fabric protectors approved by
INFINITI.
. Do not use glass or plastic cleaner on
meter or gauge lens covers. It may
damage the lens cover.
AIR FRESHENERS
Most air fresheners use a solvent that
could affect the vehicle interior. If you use
an air freshener, take the following pre-
cautions:
.Hanging-type air fresheners can cause
permanent discoloration when they
contact vehicle interior surfaces. Place
the air freshener in a location that
allows it to hang free and not contact an interior surface.
. Liquid-type air fresheners typically clip
on the ventilators. These products can
cause immediate damage and disco-
loration when spilled on interior sur-
faces.
Carefully read and follow the manufac-
turer’s instructions before using air fresh-
eners.
FLOOR MATS
WARNING
To avoid potential pedal interference that
may result in a collision or injury:
. NEVER place a floor mat on top of
another floor mat in the driver front
position.
. Use only genuine NISSAN floor mats
specifically designed for use in your
vehicle model. See your INFINITI retailer
for more information.
. Properly position the mats in the floor-
well using the floor mat positioning aid.
See “Floor mat positioning aid” (P.7-6).
The use of genuine NISSAN floor mats can extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular clean-
ing and replaced if they become exces-
sively worn.

8-4Maintenance and do-it-yourself
Keep the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism:On a fairly steep hill, check that your
vehicle is held securely with the selector
lever in the P (Park) position without
applying any brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, see an INFINITI retailer
immediately. Keep the floor mat away from
the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, see an INFINITI
retailer.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed
securely. Check the belt webbing for cuts,
fraying, wear or damage.
Seats: Check seat position controls such as seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Steering wheel:
Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly
and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera- tures or under severe condition require
frequent checks of the battery fluid level.
Brake fluid level*:
Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt
is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
(P.5-3) section for exhaust gas (carbon
monoxide).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or

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. Maintenance and do-it-yourself”
section gives instructions 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.9-32).)
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
doubt about any servicing, we recommend that it be done by an INFINITI retailer.
