7-2Appearance and care
In order to maintain the appearance of your
vehicle, it is important to take proper care of
it.
To protect the paint surface, wash your
vehicle as soon as you can:
.after a rainfall to prevent possible da-
mage from acid rain
. after driving on coastal roads
. when contaminants such as soot, bird
droppings, tree sap, metal particles or
bugs get on the paint surface
. when dust or mud builds up on the
surface
Whenever possible, store or park your
vehicle inside a garage or in a covered area.
When it is necessary to park outside, park in
a shady area or protect the vehicle with a
body cover.
Be careful not to scratch the paint surface
when putting on or removing the body
cover.WASHING
Wash dirt off the vehicle with a wet sponge
and plenty of water. Clean the vehicle
thoroughly using a mild soap, a special
vehicle soap or general purpose dishwashing
liquid mixed with clean, lukewarm (never hot)
water.
CAUTION
. Do not use car washes that use acid in
the detergent. Some car washes,
especially brushless ones, use some
acid for cleaning. The acid may react
with some plastic vehicle compo-
nents, causing them to crack. This
could affect their appearance, and
also could cause them not to function
properly. Always check with your car
wash to confirm that acid is not used.
. Do not wash the vehicle with strong
household soap, strong chemical de-
tergents, gasoline or solvents.
. Do not wash the vehicle in direct
sunlight or while the vehicle body is
hot, as the surface may become
water-spotted.
. Avoid using tight-napped or rough
cloths, such as washing mitts. Care
must be taken when removing caked- on dirt or other foreign substances so
the paint surface is not scratched or
damaged.
. Lock all doors before going through
automatic car wash. Locking doors
helps prevent fuel-filler door from
opening and becoming damaged.
Rinse the vehicle again with plenty of clean
water.
Inside flanges, seams and folds on the doors,
hatches and hood are particularly vulnerable
to the effects of road salt. Therefore, these
areas must be regularly cleaned. Make sure
that the drain holes in the lower edge of the
door are open. Spray water under the body
and in the wheel wells to loosen the dirt and
wash away road salt.
Avoid leaving water spots on the paint
surface by using a damp chamois to dry the
vehicle.
For LIMITED models, be sure to wash dirt
off the cylindrical part or lens of the side step
light with a high-pressure washing machine.
Otherwise, the brightness of the lights may
decrease due to the adhesion of dirt.
CLEANING EXTERIOR

8-2Do-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 per-
forming any parts replacement or
repairs.
. Never connect or disconnect the
battery or any transistorized compo-
nent while the ignition switch is in the
ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the igni-
tion 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 when-
ever 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
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect 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 en-
gine oil and coolant. Improperly dis-
posed engine oil, coolant, and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal 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.10-34).)
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, it is recommended you
have it done by an INFINITI retailer.
