7-8Appearance and care
MOST COMMON FACTORS CONTRI-
BUTING TO VEHICLE CORROSION
.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 accidents.
ENVIRONMENTAL FACTORS INFLU-
ENCE THE RATE OF CORROSION
Moisture
Accumulation of sand, dirt and water on the
vehicle body underside can accelerate corro-
sion. 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 where
atmospheric pollution exists, or where road salt
is used.
Temperature
A temperature increase will accelerate the rate
of corrosion 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 will
accelerate the corrosion process. Road salt will
also accelerate 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
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.
CAUTION
.NEVER remove dirt, sand or other
debris from the passenger compart-
ment by washing it out with a hose. Remove dirt with a vacuum cleaner.
. Never allow water or other liquids to
come in contact with electronic
components inside the vehicle as
this may damage them.
Chemicals used for road surface deicing 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
corrosion, which may be required in some areas,
consult a NISSAN dealer.

8-4Maintenance and do-it-yourself
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)*:When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires cannot be rotated, as the
front tires are a different size from the rear tires
and the direction of wheel rotation is fixed in
each tire.
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If
necessary, adjust the pressure in all tires,
including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive
wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.
Tire, wheel alignment and balance: If the
vehicle should pull to either side while driving on
a straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be needed.
For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the
NISSAN Warranty Information Booklet.
Windshield:
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks
or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. 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 shift 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 a NISSAN dealer 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 a NISSAN dealer.
Seat belts: Check that all parts of the seat belt
system (for example, buckles, anchors, 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 temperatures or under
severe condition require frequent checks of the
battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances. In these cases, the battery may need to be
charged to maintain battery health.
Brake and clutch fluid levels*:
Make sure
that the brake and clutch fluid levels are
between the MAX and MIN lines on the
reservoirs.
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, immediately have the exhaust
system inspected by a NISSAN dealer. (See
“Precautions when starting and driving” (P.5-2)
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 if fuel fumes are evident,
check for the cause and have it corrected
immediately. Power steering fluid level* and lines:
Check
the level with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
Underbody: The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the end
of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. For additional information, see “Cleaning
exterior” (P.7-2).
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.
Maintenance and do-it-yourself8-5

8-6Maintenance and do-it-yourself
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.
WARNING
.Park the vehicle on a level surface,
apply the parking brake securely
and block the wheels to prevent
the vehicle from moving. For man-
ual transmission models, move the
shift lever to N (Neutral) . For auto-
matic transmission models, 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 com-
ponent while the ignition switch is
in the ON position.
. Never leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition 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 disconnect the negative battery
cable before working near the fan.
. The fuel filter or fuel lines should be
serviced by a NISSAN dealer be-
cause the fuel lines are under high
pressure even when the engine is
off.
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
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 NISSAN Service Manual is also
available. (See “Owner’s Manual/Service Man-
ual order information” (P.9-25).)
