OPERATING TIPS
When the engine coolant temperature
and outside air temperature are low, the
air flow from the foot outlets may not
operate. This is not a malfunction. After
the coolant temperature warms up, air
will flow normally from the foot outlets.
The sensors
andon the instrument
panel helps maintain a constant tem-
perature. Do not put anything on or
around this sensor.
IN-CABIN MICROFILTER
The air conditioning 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 sche-
dules” section. It is recommended to see a
NISSAN dealer to replace the filter.
The filter should be replaced if air flow
is extremely decreased or when win-
dows fog up easily when operating
heater or air conditioning system.
SERVICING AIR CONDITIONER
The air conditioning system in your
NISSAN is charged with a refrigerant
designed with the environment in mind.
This refrigerant will not harm the
earth’s ozone layer. However, special
charging equipment and lubricant are
required when servicing your NISSAN air
conditioner. Using improper refrigerants
or lubricants will cause severe damage to
your air conditioning system. (See “Capa-
cities and recommended fluids/lubri-
cants” (P.10-2) for air conditioning
system refrigerant and lubricant recom-
mendations.)
Your NISSAN dealer will be able to service
your environmentally friendly air condi-
tioning 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.

THREE-WAY CATALYST
The three-way catalyst is an emission
control device installed in the exhaust
system. Exhaust gases in the three-way
catalyst are burned at high temperatures
to help reduce pollutants.
WARNING
.The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system
components.
. Do not stop or park the vehicle
over flammable materials such as
dry grass, waste paper or rags.
They may ignite and cause a fire.
CAUTION
.Do not use leaded gasoline. De-
posits from leaded gasoline ser-
iously reduce the three-way
catalyst’s ability to help reduce
exhaust pollutants.
. Keep your engine tuned up. Mal-
functions in the ignition, fuel in-
jection, or electrical systems can cause overrich fuel flow into the
three-way catalyst, causing it to
overheat. Do not keep driving if
the engine misfires, or if notice-
able loss of performance or other
unusual operating conditions are
detected. Have the vehicle in-
spected. It is recommended you
visit a NISSAN dealer for this
service.
. Avoid driving with an extremely
low fuel level. Running out of fuel
could cause the engine to misfire,
damaging the three-way catalyst.
. Do not race the engine while
warming it up.
. Do not push or tow your vehicle
to start the engine.
TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire infla-
tion pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or tire
inflation pressure label, you should deter-
mine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illumi-
nates a low tire pressure telltale when
one or more of your tires is significantly
under-inflated. Accordingly, when the low
tire pressure telltale illuminates, you
should stop and check your tires as soon
as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect
the vehicle’s handling and stopping abil-
ity.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating prop-
erly. The TPMS malfunction indicator is
combined with the low tire pressure tell-
tale. When the system detects a malfunc-
tion, the telltale will flash for
approximately one minute and then re-
Starting and driving5-3

.Recirculating the cool air in thecabin when the A/C is on reduces
cooling load.
4. Drive at economical speeds and dis- tances.
.Observing the speed limit and notexceeding 60 MPH (97 km/h)
(where legally allowed) can improve
fuel efficiency due to reduced aero-
dynamic drag.
.Maintaining a safe following dis-tance behind other vehicles re-
duces unnecessary braking.
.Safely monitoring traffic to antici- pate changes in speed permits
reduced braking and smooth accel-
eration changes.
.Select a gear range suitable to roadconditions.
5. Use cruise control.
.Using cruise control during highway driving helps maintain a steady
speed.
.Cruise control is particularly effec-tive in providing fuel savings when
driving on flat terrains.
6. Plan for the shortest route.
.Utilize a map or navigation system to determine the best route to save
time. 7. Avoid idling.
.Shutting off your engine when safe
for stops exceeding 30-60 seconds
saves fuel and reduces emissions.
8. Buy an automated pass for toll roads.
.Automated passes permit drivers to use special lanes to maintain cruis-
ing speed through the toll and
avoid stopping and starting.
9. Winter warm up.
.Limit idling time to minimize impact to fuel economy.
.Vehicles typically need no morethan 30 seconds of idling at start-
up to effectively circulate the en-
gine oil before driving.
.Your vehicle will reach its ideal
operating temperature more
quickly while driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking area or in the shade when-
ever possible.
.When entering a hot vehicle, open- ing the windows will help to reduce
the inside temperature faster, re-
sulting in reduced demand on your
A/C system. .
Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire
wear and lowers fuel economy.
. Use the recommended viscosity en-
gine oil. (See “Engine oil and oil filter
recommendation” (P.10-7).)

8-2Do-it-yourself
When performing any inspection or main-
tenance work on your vehicle, always
take care to prevent serious accidental
injury to yourself or damage to the
vehicle. The following are general precau-
tions which should be closely observed.
WARNING
.Park the vehicle on a level sur-
face, apply the parking brake
securely and block the wheels to
prevent the vehicle from moving.
For manual transmission models,
move the shift lever to N (Neutral).
For automatic transmission mod-
els, move the shift lever to P
(Park).
. Be sure the ignition switch is in
the OFF or LOCK position when
performing any parts replace-
ment or repairs.
. Never connect or disconnect the
battery or any transistorized
component while the ignition
switch is in the ON position.
. Never leave the engine or auto-
matic transmission related com-
ponent harnesses disconnected
while the ignition switch is in the
ON position. .
If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other
moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle.
. Always wear eye protection
whenever you work on your ve-
hicle.
. If you must run the engine in an
enclosed space such as a garage,
be sure there is proper ventilation
for exhaust gases to escape.
. Never get under the vehicle while
it is supported only by a jack. If it
is necessary to work under the
vehicle, support it with safety
stands.
. Keep smoking materials, flame
and sparks away from fuel tank
and the battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It
may come on at any time without
warning, even if the ignition key is
in the OFF position and the en-
gine is not running. To avoid injury, always disconnect the ne-
gative battery cable before work-
ing near the fan.
. Because the fuel lines are under
high pressure even when the
engine is off, it is recommended
you visit a NISSAN dealer for
service of the fuel filter or fuel
lines.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, coolant,
and/or other vehicle fluids can
damage the environment. Always
conform to local regulations for
disposal of vehicle fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items
which are relatively easy for an owner to
perform.
A genuine NISSAN Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-26).)
MAINTENANCE PRECAUTIONS

8-4Do-it-yourself
The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/
Coolant (blue) and 50% water to provide
year-round anti-freeze and coolant pro-
tection. The antifreeze solution contains
rust and corrosion inhibitors. Additional
engine cooling system additives are not
necessary.
WARNING
.Never remove the radiator or
coolant reservoir cap when the
engine is hot. Wait until the en-
gine and radiator cool down.
Serious burns could be caused
by high pressure fluid escaping
from the radiator. See precau-
tions in “If your vehicle overheats”
(P.6-17) of this manual.
. The radiator is equipped with a
pressure type radiator cap. To
prevent engine damage, use only
a genuine NISSAN radiator cap.
CAUTION
.Never use any cooling system
additives such as radiator sealer.
Additives may clog the cooling
system and cause damage to
the engine, transmission and/or
cooling system.
. When adding or replacing cool-
ant, be sure to use only Genuine
NISSAN Long Life Antifreeze/
Coolant (blue) or equivalent. Gen-
uine NISSAN Long Life Antifreeze/
Coolant (blue) is pre-diluted to
provide antifreeze protection to
−34°F (−37°C). If additional freeze
protection is needed due to
weather where you operate your
vehicle, add Genuine NISSAN Long
Life Antifreeze/Coolant (blue)
concentrate following the direc-
tions on the container. If an
equivalent coolant other than
Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s
instructions to maintain mini-
mum antifreeze protection to
−34°F (−37°C). The use of other
types of coolant solutions other
than Genuine NISSAN Long Life Antifreeze/Coolant (blue) or
equivalent may damage the en-
gine cooling system.
. The life expectancy of the fac-
tory-fill coolant is 105,000 miles
(168,000 km) or 7 years. Mixing
any other type of coolant other
than Genuine NISSAN Long Life
Antifreeze/Coolant (blue), includ-
ing Genuine NISSAN Long Life
Antifreeze/Coolant (green), or
the use of non-distilled water will
reduce the life expectancy of the
factory-fill coolant. Refer to the
“9. Maintenance and schedules”
section of this manual for more
details.
