OPERATING TIPS
When the engine coolant temperature
and outside air temperature are low, the
air flow from the foot outlets may not
operate. However, this is not a malfunc-
tion. After the coolant temperature
warms up, the air flow from the foot
outlets will operate normally.
The sensors
andlocated on the
instrument panel help maintain a con-
stant temperature. Do not put anything
on or around the sensors.
LINKING INTELLIGENT KEY (if so
equipped)
The air conditioner system settings can
be memorized for each Intelligent Key.
For more details, see “Setting memory
function” (P.3-42).
IN-CABIN MICROFILTER
The air conditioner system is equipped
with an in-cabin microfilter which collects
dirt, pollen, dust, etc.
To make sure the air conditioner heats,
defogs, and ventilates efficiently, replace
the filter in accordance with the specified
maintenance intervals listed in the “9.
Maintenance and schedules” section. It is
recommended to see a NISSAN dealer to
replace the filter.
The filter should be replaced if the air flow decreases significantly or if win-
dows fog up easily when operating the
heater or air conditioner.
SERVICING AIR CONDITIONER
The air conditioner system in your NISSAN
is charged with a refrigerant designed
with the environment in mind.
This re-
frigerant will not harm the earth’s
ozone layer. However, special charging
equipment and lubricant are required
when servicing your NISSAN air condi-
tioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. (See “Capa-
cities and recommended fluids/lubri-
cants” (P.10-2) for air conditioner system
refrigerant and lubricant recommenda-
tions.)
Your NISSAN dealer will be able to service
your environmentally friendly air condi-
tioner system.
WARNING
The system contains refrigerant un-
der high pressure. To avoid personal
injury, any air conditioner service
should be done only by an experi-
enced technician with the proper
equipment.
WINDOW ANTENNA

It is recommended you visit a NISSAN
dealer if checking or replacement is
required.If the brakes do not operate properly,
have the brakes checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjust-
ing brakes.

WARNING
Have your brake system checked if
the brake pedal height does not
return to normal. It is recommended
you visit a NISSAN dealer for this
service.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. 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 warning 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 infor-
mation, see the maintenance schedule
shown in the “9. Maintenance and sche-
dules” section.
BRAKE BOOSTER

rating, or if you hear steady spark knock
while holding a steady speed on level
roads, it is recommended you have a
NISSAN dealer correct the condition.
Failure to correct the condition is mis-
use of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in
knocking, after-run or overheating. This
in turn may cause excessive fuel con-
sumption or damage to the engine. If any
of the above symptoms are encountered,
have your vehicle checked. It is recom-
mended you visit a NISSAN dealer for
servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
no 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 RE-
COMMENDATION
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 fluids/
lubricants” (P.10-2). 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) certifi-
cation or International Lubricant Standar-dization and Approval Committee (ILSAC)
certification and SAE viscosity standard.
These oils have the API certification 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 necessary when the proper oil type is
used and maintenance intervals are fol-
lowed.
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 that the engine oil
viscosity be selected based on the tem-
peratures at which the vehicle will be
operated before the next oil change.
Choosing an oil viscosity other than that
recommended could cause serious en-
gine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When
replacing, use the genuine 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. Oil and
filter other than the specified quality, or
oil and filter change intervals longer than
recommended could reduce engine life.
Damage to engines caused by improper
maintenance or use of incorrect oil and
filter quality and/or viscosity is not cov-
ered by the new NISSAN vehicle limited
warranties.
Your engine was filled with a high quality
engine oil when it was built. You do nothave to change the oil before the first
recommended change interval. Oil and
filter change intervals depend upon how
you use your vehicle.
AIR CONDITIONING SYSTEM RE-
FRIGERANT AND LUBRICANT RE-
COMMENDATIONS
The air conditioning system in your
NISSAN vehicle must be charged with
the refrigerant HFC-134a (R-134a) and
the lubricant, NISSAN A/C system oil
Type S or the exact equivalents.
CAUTION
The use of any other refrigerant or
lubricant may cause severe damage
to the air conditioning system and
may require the replacement of all
air conditioner system components.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle will not harm the earth’s
ozone layer. Although this refrigerant
does not affect the earth’s atmosphere,
certain governmental regulations require
the recovery and recycling of any refrig-
erant during automotive air conditioning
system service. Your NISSAN dealer has
the trained technicians and equipment
needed to recover and recycle your air conditioning system refrigerant.
It is recommended you visit a NISSAN
dealer when servicing your air condition-
ing system.
