proper travel and make sure that the vehicle is
held securely on a fairly steep hill when only
the parking brake is applied.
Automatic transaxle P (Park) position
mechanism:On a fairly steep hill check that
the vehicle is held securely with the selector
lever in the P (Park) position without applying
any brakes.Under the hood and the vehicleThe maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Windshield washer fluid*:Check that there
is adequate fluid in the tank.
Engine coolant level*:Check the coolant
level when the engine is cold.
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, dete-
rioration or loose connections.
Brake and clutch fluid levels*:Make sure
that the brake and clutch fluid levels are be-
tween the MAX and MIN lines on the reservoir.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 conditions require frequent
checks of the battery fluid level.
Engine drive belts*:Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*:Check the level on the
dipstick after parking the vehicle on a level
spot and turning off the engine.
Power steering fluid level* and lines:Check
the level in the reservoir tank with the engine
off. Check the lines for proper attachment,
leaks, cracks, etc.
Automatic transaxle fluid level*:Check the
level on the dipstick after putting the selector
lever in P (Park) position with the engine idling.
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 locate the
trouble and correct it. (See ªPrecautions when
starting and drivingº in the ª5. Starting and
drivingº section for exhaust gas (carbon mon-
oxide).)
Underbody:The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is veryimportant 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 thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. For additional information, see
ªCleaning exteriorº in the ª7. Appearance and
careº section.
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.8-4

3. Close the radiator drain valve securely after
the coolant is drained.
4. Fill the radiator slowly with the proper mix-
ture of anti-freeze solution and demineral-
ized water/distilled water. Fill the reservoir
tank up to the MAX level. Then install the
radiator filler cap.
5. Start the engine and warm it up until it
reaches normal operating temperature.
Then race the engine 2 or 3 times under no
load.
Watch the engine coolant temperature
gauge for signs of overheating.
6. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up to the
MAX level. Check the drain valve for any
sign of leakage.
7. Recheck the coolant level after the vehicle
has been driven for a day.

Change intervalsThe oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Oil and filter other than
the specified quality, or oil and filter change
intervals longer than recommended could re-
duce engine life. Damage to engines caused
by improper maintenance or use of incorrect
oil and filter quality and/or viscosity is not
covered by the new NISSAN vehicle warran-
ties.
Your engine was filled with a high quality
engine oil when it was built. You do not have to
change the oil before the first recommended
change interval. Oil and filter change intervals
depend upon how you use your vehicle. Op-
eration under the following conditions may
require more frequent oil and filter changes.
Irepeated short distance driving at cold out-
side temperatures,
Idriving in dusty conditions,
Iextensive idling,
Itowing a trailer.
RECOMMENDED SAE VISCOSITY
NUMBERSAE 5W-30 viscosity oil is preferred for all
ambient temperatures. SAE 10W-30,
10W-40 viscosity oil may be used if the
ambient temperature is above 0ÉF (þ18ÉC).
AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONSThe air conditioning system in this NISSAN
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and the lubricant,
Nissan A/C System Oil Type S or the exact
equivalents.
CAUTION
The use of any other refrigerant or lubri-
cant will cause severe damage to the air
conditioning system and will require the
replacement of all air conditioner sys-
tem components.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle will not harm the earth's
ozone layer. Although this refrigerant does not
affect the earth's atmosphere, certain govern-
mental regulations require the recovery and
recycling of any refrigerant during automotive
air conditioning system service. Your NISSAN
dealer has the trained technicians and equip-
ment needed to recover and recycle your air
conditioning system refrigerant.
