The air cleaner filter should not be cleaned and
reused. Replace it according to the maintenance
log shown in the “NISSAN Service and Mainte-
nance Guide.”
To remove the air cleaner filter:
1Unlatch the clips and move the air cleaner
cover upward.
2. Remove the air cleaner filter.
3. Wipe the inside of the air cleaner filter hous- ing and the cover with a damp cloth. NOTE:
After installing a new air cleaner, make
sure the air cleaner cover is seated in the
housing and latch the clips.
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 the 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.
IN-CABIN MICROFILTER (if so
equipped)
The in-cabin microfilter restricts the entry of air-
borne dust and pollen particles and reduces some
objectionable outside odors. The filter is located
behind the glove box. Refer to the “NISSAN Ser-
vice and Maintenance Guide” for change intervals.
To replace the filter, perform the following proce-
dure: 1. Open the glove box and press in on the
sides so that it will open completely allowing
it to hang by the cord.

brakes checked by a NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-adjust
every time the brake pedal is applied.
WARNING
See a NISSAN dealer for a brake system
check if the brake pedal height does not
return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have audible
wear indicators. When a brake pad requires re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indicator
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 system.Proper brake inspection intervals should
be followed.
For more information regarding
brake inspections, see the appropriate mainte-
nance schedule information in the “NISSAN Ser-
vice and Maintenance Guide”.

FUEL RECOMMENDATION
Use unleaded regular gasoline with an octane
rating of at least 87 AKI (Anti-Knock Index) num-
ber (Research octane number 91) .
CAUTION
●Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect the
warranty coverage.
● Under no circumstances should a
leaded gasoline be used, because this
will damage the three-way catalyst.
● Do not use E-85 fuel in your vehicle.
Your vehicle is not designed to run on
E-85 fuel. Using E-85 fuel can damage
the fuel system components and is not
covered by the NISSAN new vehicle lim-
ited warranty.
Gasoline specifications
NISSAN recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifi-
cations where it is available. Many of the automo-
bile manufacturers developed this specification
to improve emission control system and vehicle
performance. Ask your service station manager if
the gasoline meets the WWFC specifications.
Reformulated gasoline
Some fuel suppliers are now producing reformu-
lated gasolines. These gasolines are specially
designed to reduce vehicle emissions. NISSAN
supports efforts towards cleaner air and sug-
gests that you use reformulated gasoline when
available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing oxy-
genates such as ethanol, MTBE and methanol
with or without advertising their presence.
NISSAN does not recommend the use of fuels of
which the oxygenate content and the fuel com-
patibility for your NISSAN cannot be readily de-
termined. If in doubt, ask your service 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.
● The fuel should be unleaded and have
an octane rating no lower than that
recommended for unleaded gasoline. ●
If an oxygenate-blend other than
methanol blend is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
● If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol) . It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not avail-
able to ensure that all methanol blends
are suitable for use in NISSAN ve-
hicles.
If any driveability problems such as engine stall-
ing and difficult hot-starting are experienced after
using oxygenate-blend fuels, 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.
9-4Technical and consumer information

E–85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV) . Do
not use E-85 in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square, orange
and black label with the common abbreviation or
the appropriate percentage for that region.
Aftermarket fuel additives
NISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel injec-
tor 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 solvents or
similar ingredients that can be harmful to the fuel
system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy “spark knock.” (“Spark
knock” is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on levelroads, have a NISSAN dealer correct the
condition. Failure to correct the condition
is misuse of the vehicle, for which NISSAN
is not responsible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
CAUTION
●
Your vehicle is not designed to run on
E-85 fuel. Using E-85 fuel in a vehicle
not specifically designed for E-85 fuel
can damage fuel system components
and is not covered by the NISSAN new
vehicle limited warranty.
● E-85 is a mixture of approximately 85%
fuel ethanol and 15% unleaded
gasoline. ●
U.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and
black label with the common abbrevia-
tion or the appropriate percentage for
that region.

ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade, quality
and viscosity engine oil to ensure satisfactory
engine life and performance. See “Capacities
and recommended fuel/lubricants” earlier in this
section. NISSAN recommends the use of an
energy conserving oil in order to improve fuel
economy.
Select only engine oils that meet the American
Petroleum Institute (API) certification or Interna-
tional Lubricant Standardization and ApprovalCommittee (ILSAC) certification and SAE vis-
cosity standard. These oils have the API certifica-
tion mark on the front of the container. Oils which
do not have the specified quality label should not
be used as they could cause engine damage.Oil additives
NISSAN does not recommend the use of oil
additives. The use of an oil additive is not neces-
sary when the proper oil type is used and main-
tenance intervals are followed.
Oil which may contain foreign matter or has been
previously used should not be used.
Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is important
to select the engine oil viscosity based on the
temperatures at which the vehicle will be oper-
ated before the next oil change. Choosing an oil
viscosity other than that recommended could
cause serious engine damage.
Selecting the correct oil filter
Your new NISSAN vehicle is equipped with a
high-quality genuine NISSAN oil filter. When re-
placing, use a genuine NISSAN oil filter or its
equivalent for the reason described in “Change
intervals.”
Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Using engine oil and filters
that are not of the specified quality, or exceeding
recommended oil and filter change intervals
could reduce engine life. Damage to the engine
caused by improper maintenance or use of incor-
rect oil and filter quality and/or viscosity is not
covered by the NISSAN new vehicle limited war-
ranty.
