checks of the battery fluid level.
Exhaust systemMake 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 an autho-
rized NISSAN dealer. See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.
UnderbodyThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise rust
may form on the floor pan, frame, fuel lines
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, in those areas where mud
and dirt may have accumulated. See the
``Appearance and care'' section of this
manual.
Fluid leaksCheck 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
gasoline fumes are evident, check for the
cause and have it corrected immediately.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
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shift lever
to (N) Neutral. For an automatic
transmission models, move the shift
selector lever to P (Park).
cBe sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.
cYour 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.c
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.
cIt is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
cAlways wear eye protection when-
ever you work on your vehicle.
cIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
cNever 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.
c
Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
cOn gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by an authorized NISSAN

The air cleaner filter should not be cleaned
and reused. Replace it according to the
maintenance intervals shown in the
``NISSAN Service and Maintenance Guide.''
When replacing the filter, wipe the inside of
the air cleaner filter housing and the cover
with a damp cloth.
WARNING
cOperating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops the
flame if the engine backfires. If it
isn't there, and the engine backfires,
you could be burned. Do not drive
with the air cleaner removed, and be
careful when working on the engine
with the air cleaner removed.
cNever pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.CABIN AIR FILTER (if so
equipped)
The cabin air filter restricts the entry of
airborne dust and pollen particles and re-
duces some objectionable outside odors.
The filter is located behind the glove box.
Refer to the ``Nissan Service and Mainte-
nance Guide'' for change intervals.
To replace the filter, perform the following
procedure:
