REPLACING SPARK PLUGS
Platinum-tipped spark plugsIt is not necessary to replace the platinum-
tipped spark plugs as frequently as the con-
ventional type spark plugs since they will last
much longer. Follow the maintenance sched-
ule but, do not reuse them by cleaning or
regapping.
If replacement is required, see your NISSAN
dealer for servicing.
Always replace with recommended
platinum-tipped spark plugs.The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals. See the separate Service and
Maintenance Guide. When replacing the filter,
wipe the inside of the air cleaner housing and
the cover with a damp cloth.
WARNING
IOperating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleanernot only cleans the air, it stops flame
if the engine backfires. If it is not
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed and be care-
ful when working on the engine with
the air cleaner removed.
INever pour fuel into the throttle body
or attempt to start the engine with the
air cleaner removed. Doing so could
result in serious injury.

CAUTION
IAfter wiper blade replacement, return
the wiper arm to its original position.
Otherwise it may be damaged when
the engine hood is opened.
IMake sure the wiper blade contacts
the glass, otherwise the arm may be
damaged from wind pressure.
IWorn windshield wiper blades can
damage the windshield and impair
driver vision.CLEANINGIf 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
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 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.WINDSHIELD WIPER BLADES

CHECKING PARKING BRAKEFrom the released position, pull the parking
brake lever up slowly and firmly. If the number
of clicks is out of the range listed above, see
your NISSAN dealer.
CHECKING BRAKE PEDALWith the engine running, check the distance
between the upper surface of the pedal and
the metal floor. If it is out of the range shown
above, see your NISSAN dealer.Self-adjusting brakesYour vehicle is equipped with self-adjusting
brakes.
The disc-type brakes self-adjust every time the
brake pedal is applied.
WARNING
See your NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.Brake pad wear indicatorsThe 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 indi-
cator sound is heard.
Under some driving or climate conditions, oc-
casional 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 separate Service and Maintenance Guide.

BRAKE BOOSTERCheck the brake booster function as follows:
1. With the engine off, press and release the
brake pedal several times. When brake
pedal movement (distance of travel) re-
mains 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 depressed 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 gradu-
ally with each depression as the vacuum is
released from the booster.
If the brakes do not operate properly, see your
NISSAN dealer.
CAUTION
Never use a fuse of higher amperage
rating than that specified on the fuse
box cover. This could damage the elec-
trical system or cause a fire.
ENGINE COMPARTMENTIf any electrical equipment does not operate,
check for an open fuse.
1. Be sure the ignition key and headlight
switch are OFF.
2. Open the engine hood.
3. Remove the fusible link cover.
4. Remove the fuse with the fuse puller.
5. If the fuse is open, replace it with a new
fuse.
6. If a new fuse also opens, have the electrical

HEADLIGHTS
Replacing the xenon headlight bulb
Ð low beam
WARNINGHIGH VOLTAGE
When xenon headlights are on, they
produce a high voltage. To prevent an
electric shock, never attempt to modify
or disassemble. Always have your xe-
non headlights replaced at an autho-
rized NISSAN dealer. For additional in-
formation, see ªHeadlight and turn
signal switchº in the ª2. Instruments and
controlsº section.
Replacing the halogen headlight
bulb Ð high beamThe headlight is a semi-sealed beam type
which uses a replaceable headlight (halogen)
bulb. A bulb can be replaced from inside the
engine compartment without removing the
headlight assembly.
CAUTION
High pressure halogen gas is sealed
inside the halogen bulb. The bulb may
break if the glass envelope is scratched
or the bulb is dropped.
When handling the bulb, do not touch
the glass envelope.
1. Disconnect the battery negative cable.
2. Turn the connector to loosen it.
3. Remove the headlight bulb. Do not shake
or rotate the bulb when removing it.
4. Install the new bulb in the reverse order of
removal.
Aiming is not necessary after replacing the
bulb. When aiming adjustment is neces-
sary, contact your NISSAN dealer.

FUEL RECOMMENDATIONUse unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
For improved vehicle performance,
NISSAN recommends the use of unleaded
premium gasoline with an octane rating of
at least 91 AKI number (Research octane
number 96).
CAUTION
Using a fuel other than that specified
could adversely affect the emission con-
trol devices and systems, and could
also affect the warranty coverage.
Under no circumstances should a
leaded gasoline be used, since this will
damage the three-way catalyst.Reformulated gasolineSome fuel suppliers are now producing refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
NISSAN supports efforts towards cleaner airand suggests that you use reformulated gaso-
line when available.
Gasoline containing oxygenatesSome fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and
methanol with or without advertising their pres-
ence. NISSAN does not recommend the use of
fuels of which the oxygenate content and the
fuel compatibility for your NISSAN cannot be
readily determined. If in doubt, ask your ser-
vice station manager.
If you use oxygenate-blend gasoline, please
take the following precautions as the usage of
such fuels may cause vehicle performance
problems and/or fuel system damage.
IThe fuel should be unleaded and have
an octane rating no lower than that rec-
ommended for unleaded gasoline.
IIf an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
IIf a methanol blend is used, it should
contain no more than 5% methanol (me-
thyl alcohol, wood alcohol). It should
also contain a suitable amount of appro-
priate cosolvents and corrosion inhibi-tors. If not properly formulated with ap-
propriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or ve-
hicle performance problems. At this
time, sufficient data is not available to
ensure that all methanol blends are suit-
able for use in NISSAN vehicles.
If any undesirable driveability problems such
as engine stalling and hard hot starting are
experienced after using oxygenate-blend fu-
els, immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
Aftermarket fuel additivesNISSAN does not recommend the use of any
fuel additives (i.e. fuel injector cleaner, octane
booster, intake valve deposit removers, etc.)
which are sold commercially. Many of these
additives intended for gum, varnish or deposit
removal may contain active solvent or similar
ingredients that can be harmful to the fuel
system and engine.Octane rating tipsIn most parts of North America, you should use
