Operating tips
• Keep the windows closed while the airconditioner is in operation. • Af ter parking in the sun, drive for 2 or 3
minutes with the windows open to vent
hot air from the passenger compart-
ment. Then, close the windows. This al-
lows the air conditioner to cool the inte-
rior 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 lu-
brication.
• 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 temperature
over the normal range, turn the air condi-
tioner off. For additional information, refer
to “If your vehicle overheats” in the “In case
of emergency” section of this manual.
• When Remote Engine Start (if so equipped) is activated, the manual cli-
mate control system will default to the
last used heating or cooling mode.

4-42Monitor, climate, audio, phone and voice recognition systems

• When the climate system is in automaticoperation and the engine coolant tem-
perature and outside air temperature are
low, the air flow outlet may default to de-
froster mode for a maximum of 2 min-
utes 30 seconds. This is not a malfunc-
tion. Af ter the engine coolant
temperature warms up, the air flow outlet
will return to foot mode and operation will
continue normally.
• When the outside and interior cabin tem- peratures are moderate to high, the in-
take setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may occur
when the previous climate setting was
turned off. This is not a malfunction. Af ter
the initial warm air is expelled, the intake
will return to automatic control, the air
flow outlet will return to previous settings,
and operation will continue normally. To
exit, press any climate control button.
• Keep the moonroof (if so equipped) closed while the air conditioner is in op-
eration. • If you feel that the air flow mode you have
selected and the outlets the air is coming
out do not match, select the
mode.
• When you change the air flow mode, you may feel air flow from the foot outlets for
just a moment. This is not a malfunction. 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 refrigerant and oil recommendations”
in the “Technical and consumer informa-
tion” 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 equip-
ment.
SERVICING AIR CONDITIONER
4-44Monitor, climate, audio, phone and voice recognition systems

Follow these easy-to-use Fuel Efficient
Driving Tips to help you achieve the most
fuel economy from your vehicle.
1.Use Smooth Accelerator and Brake
Pedal Application
• Avoid rapid starts and stops
• Use smooth, gentle accelerator and brake application whenever possible
• Maintain constant speed while com- muting and coast whenever possible
2. Maintain Constant Speed
• Look ahead to try and anticipate and minimize stops
• Synchronizing your speed with traffic lights allows you to reduce your num-
ber of stops
• Maintaining a steady speed can mini- mize red light stops and improve fuel
efficiency
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
Distances
• Observing the speed limit and not ex- ceeding 60 mph (97 km/h) (where le-
gally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag
• Maintaining a safe following distance behind other vehicles reduces unnec-
essary 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 cruising
speed through the toll and avoid stop-
ping 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 ef-
fectively circulate the engine oil before
driving
• Your vehicle will reach its ideal operat- ing 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 system

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 en-
gine oil and filters that are not of the speci-
fied 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 Warranty.
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 coldoutside 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
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your
NISSAN vehicle must be charged with the
refrigerant HFO-1234yf (R-1234yf ) and
NISSAN A/C system oil Type PAG 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 HFO-1234yf (R-1234yf ) in
your NISSAN vehicle does not harm the
earth's ozone layer. Although this refriger-
ant does not affect the earth's atmo-
sphere, certain government regulations re-
quire the recovery and recycling of any
refrigerant during automotive air condi-
tioner system service. A NISSAN dealer has
the trained technicians and equipment
needed to recover and recycle your air con-
ditioner system refrigerant. It is recommended that you visit a NISSAN
dealer when servicing your air conditioner
system.
