6-16In case of emergency
7. After starting your engine, carefully discon-nect the negative cable and then the positive
cable (
*4?*3?*2?*1).
8. Replace the vent caps (if so equipped). Be sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.
9. Put the battery cover on. Do not attempt to start the engine by pushing.CAUTION
.
Automatic transmission models
cannot be push-started or tow-
started. Attempting to do so may
cause transmission damage.
. Three way catalyst equipped models
should not be started by pushing
since the three way catalyst may be
damaged.
. Never try to start the vehicle by
towing it; when the engine starts,
the forward surge could cause the
vehicle to collide with the tow
vehicle.
CAUTION
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle
fire.
. To avoid the danger of being
scalded, never remove the radiator
cap while the engine is still hot.
When the radiator cap is removed,
pressurized hot water will spurt out,
possibly causing serious injury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading) , or if
you feel a lack of engine power, detect abnormal
noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply the parking brake and move the selector
lever to the P (Park) position (Automatic
transmission models). Move the shift lever to
the N (Neutral) position (Manual transmis-
sion models) .
Do not stop the engine.

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.
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 gasoline 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 selector 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.9-24).)
