CHECKING ENGINE OIL LEVEL1. Park the vehicle on a level surface and
apply parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn off the engine.Wait more than 10
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 recom-
mended oil through the opening.Do not
overfill.
6. Recheck oil level with dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the severity
of operating conditions.
Oil level should be checked regularly.
Operating with insufficient amount of oil
can damage the engine, and such dam-
age is not covered by warranty.

TEMPERATURE CONDITIONS
FOR CHECKINGIThe fluid level should be checked using the
HOT range on the dipstick after the follow-
ing conditions have been met:
a) the engine should be warmed up to
operating temperature.
b) the vehicle should be driven at least 5
minutes.
c) the automatic transmission fluid should
be warmed to between 122 and 176ÉF
(50 and 80ÉC).
IThe fluid can be checked at fluid tempera-
tures of 86 to 122ÉF (30 to 50ÉC) using the
COLD range on the dipstick after the en-
gine is warmed up and before driving. How-
ever, the fluid should be re-checked using
the HOT range.
1. Park the vehicle on a level surface and set
the parking brake.
2. Start the engine and then move the selector
lever through each gear range. Move the
selector lever to P (Park) position after you
have moved it through all ranges.3. Check the fluid level with the engine idling.
4. Remove the dipstick and wipe it clean with
lint-free paper.
5. Reinsert the dipstick into the charging pipe
as far as it will go.
6. Remove the dipstick and note the reading.
If the level is at the low side of either range,
add fluid to the charging pipe.
IDo not overfill.
IUse only NISSAN Matic D (Continen-
tal US and Alaska) or genuine auto-
matic transmission fluid (Canada).
Dexron
TMIII/Mercon
TM
or equivalent
may also be used. Outside the conti-
nental US and Alaska contact a
NISSAN dealer for more information
regarding suitable fluids, including
recommended brand(s) of Dexron

fluid.
NOTE:
If the vehicle has been driven for a long
time at high speeds, or in city traffic in hot
weather, or if it is being used to pull a
trailer, the accurate fluid level cannot be
read. You should wait until the fluid has
cooled down (about 30 minutes).

The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals. See ªPeriodic maintenance
schedulesº in the ª9. Maintenanceº section for
maintenance intervals. When replacing the
filter, wipe the inside of the air cleaner housing
and the cover with a damp cloth.IOperating the engine with the air
cleaner off can cause you or others to
be burned. The air cleaner not only
cleans the air, it stops flame if theengine backfires. If it is not there, and
the engine backfires, you could be
burned. Do not drive with it off, and
be careful working on the engine with
the air cleaner off.
INever pour fuel into the throttle body
or attempt to start the engine with the
air cleaner removed. Doing so could
result in serious injury.
CLEANINGIf your windshield is not clear after using the
windshield washer or if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your
windshield is clean if beads do not form when
rinsing with clear water.
Clean the blade by wiping it with a cloth
soaked in a washer solution or a mild deter-
gent. Then rinse the blade with clear water. If
your windshield is still not clear after cleaning
the blades and using the wiper, replace the
blades.
