Servicing air conditioner
The air conditioner system in your NISSAN
is charged with a refrigerant designed with
the environment in mind.
This refrigerant does not harm the
earth's ozone layer.
Special charging equipment and lubricant is
required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants causes severe damage to your
air conditioner system. See ``Air conditioner
system refrigerant and lubricant recommen-
dations'' in the ``Technical and consumer
information'' section of this manual.
An authorized NISSAN dealer will be able to
service your environmentally ``friendly'' air
conditioner system.
WARNING
The air conditioner system contains
refrigerant under high pressure. To
avoid personal injury, any air condi-
tioner service should be done only by
an experienced technician with proper
equipment.

1. Move the heater or air conditioner tem-
perature control dial to the maximum hot
position.
2. Open the radiator drain plug. Open the
drain plug on the engine block.3. Open the radiator cap to drain the cool-
ant.
4. Flush the cooling system by running
fresh water through the radiator.
5. Close the drain plugs on the radiator and
the engine block securely.
6. See the ``Technical and consumer infor-
mation'' section for cooling system ca-
pacity. Fill the radiator slowly with the
proper mixture of coolant and water. Fill
the reservoir tank up to the MAX level.
7. Open and close the air release plug(s) to
release air. Then fill the radiator again
and install the radiator cap.
8.
Start the engine, and warm it up until it
reaches normal operating temperature.
Then race the engine two or three times
under no load. Watch the engine coolant
temperature gauge for signs of overheating.

6. Clean and reinstall the drain plug and
washer. Securely tighten the drain plug
with a wrench.
Drain plug tightening torque:
22 to 29 ft-lb
(29 to 39 N²m)
Do not overtighten.
7. Refill engine with recommended oil
through the oil filler opening then install
the oil filler cap securely.
See the ``Technical and consumer infor-
mation'' section for refill capacity.8. Start the engine. Check for leakage
around the drain plug and oil filter. Cor-
rect as required.
9. Turn the engine off and wait several
minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
WARNING
cProlonged and repeated contact with
used engine oil may cause skin can-
cer.
cTry to avoid direct skin contact with
used oil. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible.
cKeep used engine oil out of reach of
children.
CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface and
apply the parking brake.
2. Turn the engine off.
3. Place a large drain pan under the oil
filter.
4. Loosen the oil filter with an oil filter
wrench. Then remove the oil filter by
turning it by hand.
CAUTION
Be careful not to burn yourself. The
engine oil may be hot.

WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to
remove the plugs. An incorrect socket
can cause damage.
GA16DE Engine
1. Remove brackets as necessary to give
access to the high tension cables and
spark plugs.
2. Disconnect the spark plug cables from
the spark plugs.
When disconnecting, always hold the
boots, not the cables. Mark all cables to
identify their original locations.
3. Remove the spark plugs with a spark
plug socket.
The spark plug socket has a rubber seal
that holds the spark plug so it does not
fall when it is pulled out. Make sure each
spark plug is snugly fitted into the spark
plug socket.
4. On conventional spark plugs, check the
gap on each new spark plug with a
feeler gauge. (The spark plug gap is
shown in the ``Technical and consumer
information'' section of this manual.) Ad-
just the gap as required.

WARNING
cAfter rotating the tires, adjust the tire
pressure.
cRetighten the wheel nuts after the
wheels have been run for the first
600 miles (1,000 km) (also in cases of
a flat tire, etc.).
cDo not include the T-type spare tire
in the tire rotation.
Tire wear and damage
WARNING
c
Tires should be periodically inspected
for wear, cracking, bulging, or objects
caught in the tread. If excessive wear,
cracks, bulging, or deep cuts are
found, the tire should be replaced.
cThe original tires have a built-in
tread wear indicator. When the wear
indicator is visible, the tire should be
replaced.
c
Improper service for a T-type spare tiremay result in serious personal injury. If
it is necessary to repair the T-type
spare tire, contact your NISSAN dealer.
Changing tires and wheels
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. Recom-
mended types and sizes are shown in
``Wheel/Tire Size'' of the ``Technical and
consumer information'' section of this
manual.
WARNING
c
The use of tires other than those
recommended, or the mixed use of
tires of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, snow chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.

Your new NISSAN has been designed to
have minimum maintenance requirements
with longer service intervals to save you
both time and money. However, some day-
to-day and regular maintenance is essential
to maintain your NISSAN's good mechani-
cal condition, as well as its emission and
engine performance.
It is the owner's responsibility to make sure
the specified periodic maintenance, as well
as general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
proper maintenance. You are a vital link in
the maintenance chain.
General maintenance
General maintenance includes those items
which should be checked during normal
day-to-day operation of the vehicle. They
are essential if your vehicle is to continue to
operate properly. It is your responsibility to
perform these maintenance procedures
regularly as prescribed.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, an authorized NISSAN dealer.
Periodic maintenance
The maintenance items listed under peri-
odic maintenance are required to be ser-
viced at regular intervals.
However, under severe driving conditions,
additional or more frequent maintenance is
required.
Where to go for service
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and tuned by an autho-
rized NISSAN dealer.
NISSAN technicians are well-trained spe-
cialists who are kept up to date with the
latest service information through technical
bulletins, service tips, and in-dealership
training programs. They are completely
qualified to work on NISSAN vehiclesbe-
forethey work on your vehicle, rather than
after they have worked on it.
You can be confident that an authorized
NISSAN dealer's service department per-
forms the best job to meet the maintenance
requirements on your vehicle Ð in a reliable
and economical way.During the normal day-to-day operation of
the vehicle, general maintenance should be
performed regularly as prescribed in this
section. If you detect any unusual sounds,
vibrations or smells, be sure to check for the
cause or have an authorized NISSAN
dealer do it promptly. In addition, you should
notify an authorized NISSAN dealer if you
think repairs are required.When performing any checks or maintenance
work, closely observe the precautions in the
``Do-it-yourself'' section of this manual.
OUTSIDE THE VEHICLE
The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself'' section of this manual.
Tires* ÐCheck the pressure with a gauge
periodically when at a service station, in-
cluding the spare, and adjust to the speci-
fied pressure if necessary. Check carefully
for damage, cuts or excessive wear.
Wheel nuts* ÐWhen checking the tires,
make sure no wheel nuts are missing, and
