Iridium-tipped spark plugsGUID-4C8CEFDE-424F-4945-8A13-7DFAE22BFEE0It is not necessary to replace the iridium-
tipped spark plugs as frequently as the
conventional type spark plugs since they
will last much longer. Follow the main-
tenance schedule in“INFINITI Service and
Maintenance Guide”, but do not reuse
them by cleaning or regapping. Always replace spark plugs with recom-
mended or equivalent ones.

Remove the retainers*1as illustrated and
pull out the filter element
*2.
The filter element should not be cleaned
and reused. Replace it according to the
maintenance intervals. See “INFINITI Ser-
vice and Maintenance Guide” for mainte-
nance intervals. When replacing the filter, wipe the inside of the air cleaner housing
and the cover with a damp cloth.
WARNING
.
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 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.
. 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.

the windshield washer or if a wiper blade
chatters when running, wax or other
material may be on the blade or wind-
shield.
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 each blade by wiping it with a cloth
soaked in a washer solution or a mild
detergent. 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.
Worn windshield wiper blades can damage
the windshield and impair driver vision.

SELF-ADJUSTING BRAKESGUID-2D98160D-8918-4BF3-999B-F13E2922E177Your vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every time
the brake pedal is applied.
WARNING
See an INFINITI retailer for a brake system
check if the brake pedal height does not
return to normal.
BRAKE PAD WEAR WARNINGGUID-0D7DECB1-F0F3-4C66-A768-32FE17341FFFThe disc brake pads have audible wear
warnings. When a brake pad requires
replacement, it will make a high pitched
scraping sound when the vehicle is in
motion. This scraping sound will first occur
only when the brake pedal is depressed.
After more wear of the brake pad, the
sound will always be heard even if the
brake pedal is not depressed. Have the
brakes checked as soon as possible if the
wear warning sound is heard.
Under some driving or climate conditions, occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is
normal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.
For additional information,
see the maintenance log section of your
“INFINITI Service and Maintenance Guide”
for maintenance intervals.
