2019 NISSAN ALTIMA air conditioning

∙ Af ter parking in the sun, drive for 2 or3 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 pre-
vent 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 in-
formation, refer to “If your vehicle over-
heats” 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.AIR FLOW CHARTS
The following charts show the button and
dial positions for MAXIMUM AND QUICK
heating, cooling or defrosting. The
air
recirculation button should always be in
the off position for heating and defrost-
ing.

Remote Engine Start with
Intelligent Climate Control (if so
equipped)
Vehicles equipped with automatic climate
controls and Remote Engine Start function
may go into automatic heating or cooling
mode when Remote Engine Start is acti-
vated depending on outside and cabin
temperatures. During this period, the cli-
mate control display and buttons will be
inoperable until the ignition switch is
turned on. In Remote Engine Start defrost-
ing mode, the rear window defroster and
heated steering wheel (if so equipped) may
be activated automatically.
MANUAL OPERATION
Fan speed control buttons
Press thefan speed control buttons
to manually control the fan speed.
Press the AUTO button to return to auto-
matic control of the fan speed.
Temperature control dial
The temperature control dial allows you to
adjust the temperature of the outlet air. To
lower the temperature, turn the dial to the
lef t. To increase the temperature, turn the dial to the right. Temperature can be ad-
justed on the driver’s and passenger’s side.
Air recirculation
Press theair recirculation button to
recirculate interior air inside the vehicle.
The
indicator light on the button will
come on.
The air recirculation cannot be activated
when the air conditioner is in the
front defrosting mode.
When the outside temperature exceeds
70°F (21°C), the air conditioning system may
default to air recirculation mode automati-
cally to reduce overall power consumption.
To exit air recirculation mode, deselect the
air recirculation button (indicator light will
turn off ) to enter fresh air mode.
Automatic intake air control
In the AUTO mode, the intake air will be
controlled automatically. To manually con-
trol the intake air, press the
air recir-
culation button. To return to the automatic
control mode, press and hold the
air
recirculation button for about 2 seconds.
The indicator light will flash twice, and then
the intake air will be controlled automati-
cally.
A/C (air conditioner) button
Start the engine, press thefan speed
control buttons to the desired position and
press the
button to turn on the air
conditioner. To turn off the air conditioner,
press the
button again.
The air conditioner cooling function op-
erates only when the engine is running.
Air flow control
Pressing thebutton manually con-
trols air flow and selects the air outlet:
— Air flows from center and side
vents.
— Air flows from center and sidevents and foot outlets.
— Air flows mainly from footoutlets.
— Air flows from defroster andfoot outlets.
Synchronize climate settings
Press the SYNC button to synchronize cli-
mate settings. The sync indicator will turn
on.
Pressing SYNC will synchronize driver’s and
front passenger’s climate settings.

CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to ob-
tain maximum engine performance
and ensure the future reliability and
economy of your new vehicle. Failure to
follow these recommendations may re-
sult in shortened engine life and re-
duced engine performance.∙ Avoid driving for long periods at con- stant speed, either fast or slow, and do
not run the engine over 4,000 rpm.
∙ Do not accelerate at full throttle in any gear.
∙ Avoid quick starts.
∙ Avoid hard braking as much as pos- sible. 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 pos-
sible.
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 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.

Technical and consumer information10-3

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 operated before
the next oil change. Choosing an oil viscos-
ity 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 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 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
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
(VC100YF oil) or the exact equivalents.
CAUTION
The use of any other refrigerant or oil
will cause severe damage to the air con-
ditioning system and will require the re-
placement 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 refrigerant does
not affect the earth’s atmosphere, certain
government regulations require the recovery
and recycling of any refrigerant during auto-
motive air conditioner system service. Air
conditioner system should only be serviced
by trained and certified technicians to ensure
proper and safe operation (SAE J2845). A
NISSAN dealer has the trained technicians
and equipment needed to recover and re-
cycle your air conditioner system refrigerant.
Only new and SAEJ2842 certified evapora-
tor(s) shall be used as replacement parts.
A damaged or leaking air conditioning
evaporator shall never be repaired or re-
placed with one removed from a used or
salvaged vehicle. To replace a damaged or
leaking evaporator, use only new and SAE
J2842 certified evaporator(s). It is recom-
mended that you visit a NISSAN dealer when
servicing your air conditioner system.
