nance log shown in the ªINFINITI Service and
Maintenance Guideº. When replacing the filter,
wipe the inside of the air cleaner housing and
the cover with a damp cloth.
WARNING
cOperating 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 work-
ing on the engine with the air cleaner
removed.
c Never pour fuel into the throttle body or at-
tempt to start the engine with the air cleaner
removed. Doing so could result in serious
injury.
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 wind-
shield 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 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.
CAUTION
Worn windshield wiper blades can damage the
windshield and impair driver vision.

REPLACING
Replace the wiper blades if they are worn.
1. Push the ignition switch to the ON posi-tion and turn the windshield wiper switch
on. Push the ignition switch to the LOCK
position when the wiper is in the fully up
position. The wiper will stop as illustrated.
The wiper should be in the fully up position to
avoid scratching the engine hood or wiper
arm.
2. Pull the wiper arm.
3. Push the release tab
sA, and then move
the wiper blade down the wiper arm
s1
while pushing the release tab to remove.
4. Insert the new wiper blade onto the wiper arm until a click sounds.
5. Rotate the wiper blade so the dimple is in the groove.
CAUTION
cAfter wiper blade replacement, return the
wiper arm to its original position;
otherwise it may be damaged when the hood
is opened.
c Make sure the wiper blades contact the
glass; otherwise the arm may be damaged
from wind pressure.

If you wax the surface of the hood, be careful
not to let wax get into the washer nozzle
sA.
This may cause clogging or improper wind-
shield washer operation. If wax gets into the
nozzle, remove it with a needle or small pin
sB. If the brakes do not operate properly, have the
brakes checked by an INFINITI retailer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjusting
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 WARNINGS
The disc brake pads have audible wear warn-
ings. 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 warn-
ing sound is heard.
Under some driving or climate conditions, occa-
sional 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 sys-
tem.
Proper brake inspection intervals should be fol-
lowed.
For additional information, see the main-
tenance log section of your ªINFINITI Service
and Maintenance Guideº.

Some vehicles are equipped with engine com-
partment and passenger compartment fuse
boxes that use only type
sAfuses. Other ve-
hicles are equipped with type
sAfuses in the
engine compartment fuse box and type
sB
fuses in the passenger compartment fuse box.
Type
sAfuses are provided as spare fuses. They
are stored in the passenger compartment fuse
box.
Type
sAfuses can be installed in the engine
compartment and passenger compartment fuse
boxes. If a type
sAfuse is used to replace a typesB
fuse, the typesAfuse will not be level with the
fuse pocket as shown in the illustration. This
will not affect the performance of the fuse.
Make sure the fuse is installed in the fuse box
securely.
Type
sBfuses cannot be installed in the under-
hood fuse boxes. Only use type
sAfuses in the
underhood fuse boxes.
ENGINE COMPARTMENT
