REPLACING SPARK PLUGS If replacement is required, see an INFINITI
dealer for servicing.
Platinum-tipped spark plugs It is not necessary to replace the
platinum-tipped
q A
spark plugs as fre-
quently as the conventional type spark
plugs since they will last much longer.
Follow the maintenance schedule in the
INFINITI Service and Maintenance Guide,
but do not reuse them by cleaning or re-
gapping. Always replace with recommended
platinum-tipped spark plugs. If maintenance is required, see an INFINITI
dealer for servicing.
The filter element should not be cleaned
and reused. Replace it according to the
maintenance intervals. See the INFINITI
Service and Maintenance Guide. When re-
placing the filter, wipe the inside of the
air cleaner housing and the cover with a
damp cloth.
WARNING O 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 the flame if the engine
backfires. If it is not there, and the en-
gine backfires, you could be burned. Do
not drive with the air cleaner removed,
and be careful when working on the en-
gine 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.SDI0145D

CAUTIONO 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 blades contact the
glass, otherwise the arms may be dam-
aged 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 ma-
terial 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 de- tergent. 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.

parking brake pedal slowly and firmly,
and check the notches between the initial
and final position of the pedal

.Ifitis
out of the range, see an INFINITI dealer.
Range

: 2 to 3 notches under a de-
pressing force of 44 lb (196

ing brake lever up slowly and firmly. If the
number of clicks is out of the range

Self-adjusting brakes Your vehicle is equipped with self-
adjusting brakes.
The disc-type brakes self-adjust every
time the brake pedal is applied.
WARNINGSee an INFINITI dealer for a brake system
check if the brake pedal height does not re-
turn to normal.
Brake pad wear indicators The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it will make a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear in-
dicator 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 appropriate maintenance log
shown in the INFINITI Service and Mainte-
nance Guide.
High performance sports brake pads oc-
casionally make squeaks, squeals or
other braking noises because of their very
high friction coefficient.
These occasional brake noises are
normal, but if they continue, see an
INFINITI dealer.
BRAKE BOOSTER Check the brake booster function as fol-
lows:
1. With the engine off, press and release
the brake pedal several times. When
brake pedal movement (distance of
travel) remains the same from one
pedal application to the next, continue
on to the next step.
2. While depressing the brake pedal,
start the engine. The pedal height
should drop a little. 3. With the brake pedal depressed, stop
the engine. Keeping the pedal de-
pressed for about 30 seconds, the
pedal height should not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn
it off. Depress the brake pedal several
times. The pedal travel distance will
decrease gradually with each depres-
sion as the vacuum is released from
the booster.
If the brakes do not operate properly, see
an INFINITI dealer.

Two types of fuses are used. Type
q A
is
used in the fuse boxes in the engine com-
partment. Type
q B
is used in the passen-
ger compartment fuse box.
Type
q A
fuses are provided as spare
fuses. They are stored in the passenger
compartment fuse box.
Type
q A
fuses can be installed in the en-
gine compartment and passenger com-
partment fuse boxes. If a type
q A
fuse is used to replace a type
q B
fuse, the type
q A
fuse will not be level
with the fuse pocket as shown in the il-
lustration. This will not affect the perfor-
mance of the fuse. Make sure the fuse is
installed in the fuse box securely.
Type
q B
fuses cannot be installed in the
underhood fuse boxes. Only use type
q A
fuses in the underhood fuse boxes. ENGINE COMPARTMENT
CAUTION Never use a fuse of a higher or lower am-
perage rating than that specified on the fuse
box cover. This could damage the electrical
system or cause a fire.
If any electrical equipment does not oper-
ate, check for an open fuse.
1. Be sure the ignition switch and head-
light switch are in the OFF position.SDI1751 SDI1752 SDI1392A

ate and fuses are in good condition,
check the fusible links. If any of these
fusible links are melted, replace only with
genuine INFINITI parts. SDI1753
