CHECKING ENGINE OIL LEVEL 1. 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. CAUTION 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.SDI1386 SDI1402

filler opening. Do not overfill.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
1. Remove the cell plugs.
2. Add distilled water up to the MAX level.

unexpectedly.
1. Visually inspect each belt for signs of un-
usual wear, cuts, fraying, oil adhesion or
looseness. If the belt is in poor condition or
loose, have it replaced or adjusted by your
INFINITI retailer.
2. Have the belts checked regularly for condi-
tion and tension in accordance with the
maintenance schedule in this manual.

REPLACING SPARK PLUGS If replacement is required, see your INFINITI
retailer for servicing.
Platinum-tipped spark plugs It is not necessary to replace the platinum-
tipped spark plugs as frequently as the con-
ventional type spark plugs since they will last
much longer. Follow the maintenance sched-
ule but, do not reuse them by cleaning or
regapping.
Always replace with recommended
platinum-tipped spark plugs. SDI0145

If maintenance is required, see your INFINITI
retailer for servicing.
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.
WARNINGO Operating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine backfires. If it is not
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed and be care-
ful when working on the engine with
the air cleaner removed.
O Never pour fuel into the throttle body
or attempt to start the engine with the
air cleaner removed. Doing so could
result in serious injury. CAUTION O After wiper blade replacement, return
the wiper arm to its original position.
Otherwise it may be damaged when
the engine hood is opened.
O Make sure the wiper blade contacts
the glass, otherwise the arm may be
damaged from wind pressure.
O Worn windshield wiper blades can
damage the windshield and impair
driver vision.
CLEANING If 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.
