Replace the spark plugs according to the main-
tenance schedule shown in a separate mainte-
nance booklet.
If replacement is required, it is recommended
that you visit an INFINITI retailer.
Always replace spark plugs with recommended
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 remove
the spark plugs. An incorrect socket can
cause damage to the spark plugs.It is recommended that you visit an INFINITI
retailer if checking or replacement is required.
WARNING
•Operating the engine with the air cleaner
filter off can cause you or others to be
burned. The air cleaner filter not only cleans
the intake air, it also stops the flame if the
engine backfires. If the air cleaner is not
installed and the engine backfires, you
could be burned. Never drive with the air
cleaner filter off. Be cautious working on the
engine when the air cleaner is off.
•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.
CLEANING
If the windshield or rear window is not clear
after using the window 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 or rear
window with a washer solution or a mild deter-
gent. The windshield or rear window 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 detergent. Then
rinse the blade with clear water. If the wind-
shield or rear window is still not clear after
cleaning the blades and using the wiper, re-
place the blades.
CAUTION
Worn windshield wiper blades can damage the
windshield and impair driver vision.
