the desired position.
4. Press the

5. Turn the temperature control dial to the desired position.
Dehumidified defogging
This mode is used to defog the windows
and dehumidif y the air.
1. Press the
air flow control button.
2. Turn the
fan speed control dial to
the desired position.
∙ When the
orare selected,
the air conditioner automatically turns
on if the outside temperature is more
than 36°F (2°C). This dehumidifies the air
which helps defog the windshield.
The
mode automatically turns off,
allowing outside air to be drawn into the
passenger compartment to further im-
prove the defogging performance.
∙ The air conditioner is always on in
mode, regardless of whether the indica-
tor light is on or off.
3. Turn the temperature control dial to the desired position.
Operating tips
∙ Keep the windows and moonroofclosed while the air conditioner is in op-
eration.
∙ Af ter parking in the sun, drive for 2 or 3 minutes with the windows open to
vent hot air from the passenger com-
partment. Then, close the windows.
This allows the air conditioner to cool
the interior more quickly.
∙ The air conditioning system should
be operated for approximately
10 minutes at least once a month.
This helps prevent damage to the
system due to lack of lubrication.
∙ A visible mist may be seen coming from the ventilators in hot, humid conditions
as the air is cooled rapidly. This does not
indicate a malfunction.
∙ If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. For additional
information, refer to “If your vehicle
overheats” in the “In case of emer-
gency ” section of this manual.
AIR FLOW CHARTS
The following charts show the button and
dial positions for MAXIMUM AND QUICK
heating, cooling or defrosting. The air re-
circulation button should always be in
the OFF position for heating and defrost-
ing.

OPERATING TIPS
The sunload sensor, located on the top
passenger’s side of the instrument panel,
helps the system maintain a constant
temperature. Do not put anything on or
around this sensor.∙ When the engine coolant temperature and outside air temperature are low, the
air flow from the foot outlets may not
operate for a maximum of 150 seconds.
However, this is not a malfunction. Af ter
the coolant temperature warms up, air
flow from the foot outlets will operate
normally. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth’s ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, refer to “Air conditioner sys-
tem (if so equipped) refrigerant and oil rec-
ommendations” in the “Technical and con-
sumer information” section of this manual.
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly” air conditioning system.
WARNING
The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper
equipment.
RADIO
Place the ignition switch in the ACC or ON
position and press the PUSH
button to
turn the radio on. If you listen to the radio
with the engine not running, the ignition
switch should be placed in the ACC position.
Radio reception is affected by station sig-
nal strength, distance from radio transmit-
ter, buildings, bridges, mountains and other
external influences. Intermittent changes
in reception quality normally are caused by
these external influences.
Using a cellular phone in or near the vehicle
may influence radio reception quality.
Radio reception
Your NISSAN radio system is equipped with
state-of-the-art electronic circuits to en-
hance radio reception. These circuits are
designed to extend reception range, and to
enhance the quality of that reception.
However, there are some general charac-
teristics of both FM and AM radio signals
that can affect radio reception quality in a
moving vehicle, even when the finest
equipment is used. These characteristics
are completely normal in a given reception
area and do not indicate any malfunction
in your NISSAN radio system.

3.Use Air Conditioning (A/C) at Higher
Vehicle Speeds
∙ Below 40 mph (64 km/h), it is more efficient to open windows to cool the
vehicle due to reduced engine load
∙ Above 40 mph (64 km/h), it is more efficient to use A/C to cool the vehicle
due to increased aerodynamic drag
∙ Recirculating the cool air in the cabin when the A/C is on reduces cooling
load
4. Drive at Economical Speeds and Dis-
tances
∙ Observing the speed limit and not exceeding 60 mph (97 km/h) (where
legally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag
∙ Maintaining a safe following distance behind other vehicles reduces un-
necessary braking
∙ Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes
∙ Select a gear range suitable to road conditions 5.
Use Cruise Control
∙ Using cruise control during highway driving helps maintain a steady
speed
∙ Cruise control is particularly effective 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 more than 30 seconds of idling at start-up to
effectively circulate the engine oil be-
fore driving
∙ Your vehicle will reach its ideal oper- ating temperature more quickly
while driving versus idling
10. Keeping your Vehicle Cool
∙ Park your vehicle in a covered parking area or in the shade whenever pos-
sible
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C sys-
tem
11. ECO Mode
∙ The ECO mode helps to enhance the fuel economy by controlling the en-
gine and Continuously Variable
Transmission (if so equipped) opera-
tion automatically to avoid rapid ac-
celeration.

Technical and consumer information10-3

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 recom-
mended 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 outside temperatures
∙ driving in dusty conditions
∙ extensive idling
∙ stop and go commuting
For additional information, refer to the
“Maintenance and schedules” section of
this manual.AIR CONDITIONER SYSTEM (if so
equipped) REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your
NISSAN vehicle must be charged with the
refrigerant HFC-134a (R-134a) and
NISSAN A/C system oil Type S (DH-PS) or
the exact equivalents.
CAUTION
The use of any other refrigerant or oil
may cause severe damage to the air
conditioning system and will require
the replacement 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 regulations require the recov-
ery and recycling of any refrigerant during
automotive air conditioner system service.
A NISSAN dealer has the trained techni-
cians and equipment needed to recover
and recycle your air conditioner system re-
frigerant. It is recommended that you visit a NISSAN
dealer when servicing your air conditioner
system.
