If the cooling system frequently requires
coolant, have it checked by your NISSAN
dealer.
CHANGING ENGINE COOLANT
Your NISSAN dealer can change the engine
coolant. The service procedure is found in
NISSAN's service manual.
Improper servicing can result in reduced
heater performance and engine
overheating.
WARNING
cTo avoid danger of being scalded,
never change the coolant when the
engine is hot.
cNever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn the engine off.Wait a few minutes
for the oil to drain back into the oil
pan.
4. Remove the dipstick and wipe it clean.
Reinsert it all the way.5. Remove the dipstick again and check the
oil level. It should be between the H and
L marks. If the oil level is below the L
mark, remove the oil filler cap and pour
recommended oil through the opening.
Do not overfill.
6. Recheck the oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-
ity of operating conditions.

CAUTION
cOil level should be checked regu-
larly. Operating with an insufficient
amount of oil can damage the en-
gine, and such damage is not cov-
ered by warranty.
CHANGING ENGINE OIL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating
temperature, then turn it off.
3. Place a large drain pan under the drain
plug.
4. Remove the oil filler cap.
5. Remove the drain plug with a wrench and
completely drain the oil.If the oil filter is to be changed, remove
and replace it at this time. See ``Chang-
ing the oil filter'' later in this section.
WARNING
cBe careful not to burn yourself, as
the engine oil is hot.
cProlonged and repeated contact with
used engine oil may cause skin
cancer.
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.
Waste oil must be disposed of properly.
Check your local regulations.
6. Clean and re-install the drain plug with a
new washer. Securely tighten the drain
plug with a wrench.

API CERTIFICATION MARK cannot be
found.
Mineral based or synthetic type oils may be
used in your NISSAN vehicle. These oils
must, however, meet the API quality and
SAE viscosity ratings specified for your ve-
hicle. Do not mix mineral based and syn-
thetic type oils in the engine.
Oil additives
NISSAN does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
Oil viscosity
The engine oil viscosity or thickness
changes with temperature. Because of this,
it is important to select the engine oil viscos-
ity based on the temperatures at which the
vehicle will be operated before the next oil
change. The chart ``Recommended SAE
viscosity number'' shows the recommended
oil viscosities for the expected ambient tem-
peratures. Choosing an oil viscosity otherthan that recommended could cause seri-
ous engine damage.
Selecting the correct oil filter
Your new NISSAN vehicle is equipped with
a high- quality genuine NISSAN oil filter.
When replacing, use a genuine NISSAN oil
filter or its equivalent for the reason de-
scribed in ``Change intervals''.
Change intervals
The 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 reduce engine life. Damage to the
engine caused by improper maintenance or
use of incorrect oil and filter quality and/or
viscosity is not covered by the new NISSAN
vehicle warranties.
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 recom-
mended change interval. Oil and filter
change intervals depend upon how you use
your vehicle. Operation under the following
conditions may require more frequent oil
and filter changes:Ð repeated short distance driving at cold
outside temperatures,
Ð driving in dusty conditions,
Ð extensive idling,
Ð towing a trailer.
