To remove the air cleaner filter:● Unlatch the clips and move the air cleaner
cover upward.
● Remove the air cleaner filter.
● 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 oth-
ers 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. For additional in-
formation, refer to the “NISSAN Service and
Maintenance Guide” for change intervals.
If replacement is required, see a NISSAN dealer.
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
fluid 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 fluid or a mild detergent. Then rinse
the blades with clear water. If your windshield is
still not clear after cleaning the blades and using
the wiper, install new windshield wiper blades.
CAUTION
Worn windshield wiper blades can dam-
age the windshield and impair driver
vision.

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.

RECOMMENDED FLUIDS/
LUBRICANTS AND CAPACITIES
9-2Technical and consumer information

●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.E–15 fuel
E-15 fuel is a mixture of approximately 15% fuel
ethanol and 85% unleaded gasoline. E-15 can
only be used in vehicles designed to run on E-15
fuel. Do not use E-15 in your vehicle. U.S. gov-
ernment regulations require fuel ethanol dispens-
ing pumps to be identified with small, square,
orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
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 level
roads, 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.

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. For additional infor-
mation, refer to “Recommended fluids/lubricants
and capacities” in this section. NISSAN recom-
mends 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
replacing, 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.
LTI2051
9-6Technical and consumer information

Your engine was filled with a high-quality engine
oil when it was built. You do not have to change
the oil before the first recommended change
interval. Oil and filter change intervals depend
upon how you use your vehicle.
Operation under the following conditions may
require more frequent oil and filter changes:● repeated short distance driving at cold out-
side temperatures
● driving in dusty conditions
● extensive idling
● towing a trailer
● stop and go commuting
For additional information, refer to the “NISSAN
Service and Maintenance Guide” for the mainte-
nance schedule.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your NISSAN
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and NISSAN A/C
system oil Type S or the exact equivalents.
CAUTION
The use of any other refrigerant or oil will
cause severe damage to the air condition-
ing system and will require the replace-
ment of all air conditioner system
components.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle does not harm the earth’s ozone
layer. Although this refrigerant does not affect the
earth’s atmosphere, certain government regula-
tions require the recovery and recycling of any
refrigerant during automotive air conditioner sys-
tem service. A NISSAN dealer has the trained
technicians and equipment needed to recover
and recycle your air conditioner system refriger-
ant.
Contact a NISSAN dealer when servicing your air
conditioner system.
