REPLACING SPARK PLUGS
Platinum-tipped spark plugs
It is not necessary to replace platinum-tipped
spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance schedule, but do not reuse
the spark plugs by cleaning or regapping.
cAlways replace spark plugs with rec-
ommended or equivalent ones.
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 re-
move the spark plugs. An incorrect socket
can damage the spark plugs.

Except supercharger
1. Disconnect the spark plug cables.
When disconnecting, always hold the
boots — not the cables. Mark all cables
to identify their original location.
2. Remove the spark plugs with a spark plug
socket.
The 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.3. Fit the new plugs, one at a time, into the
spark plug socket and install them.Use
only the specified spark plugs.Turn
each plug several full turns by hand, then
tighten with the spark plug socket to the
correct torque. Do not overtighten.Spark plug tightening torque:
14 - 22 ft-lb (20 - 29 N·m)
4. Reconnect the spark plug cables to their
original positions.
With Supercharger
If replacement is required, please see your
NISSAN dealer for assistance.

The air cleaner filter should not be cleaned and
reused. Replace it according to the maintenance
intervals shown in the “NISSAN Service and
Maintenance Guide.” When replacing the filter,
wipe the inside of the air cleaner filter housing
and the cover with a damp cloth.WARNING
cOperating the engine with the air
cleaner removed can cause you or oth-
ers to be burned. The air cleaner not
only cleans the air, it stops the flame if
the engine backfires. If it isn’t there, and
the engine backfires, you could be
burned. Do not drive with the air cleaner
removed, and be careful when working
on the engine with the air cleaner
removed.cNever pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.
IN-CABIN MICROFILTER (if so
equipped)

borne dust and pollen particles and reduces
some objectionable outside odors. The filter is
located behind the glove box. Refer to the
“NISSAN Service and Maintenance Guide” for
change intervals.

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.

solution or a mild detergent. Your windshield is
clean if beads do not form when rinsing with clear
water.
Clean each blade by wiping it with a cloth soaked
in a washer solution or a mild detergent. Then
rinse the blades with clear water. If your wind-
shield is still not clear after cleaning the blades
and using the wiper, replace the blades.
CAUTION
Worn windshield wiper blades can dam-
age the windshield and impair driver
vision.

glass; otherwise the arms may be dam-
aged from wind pressure.
