2019 NISSAN ALTIMA engine

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.

SPECIFICATIONS
10-8Technical and consumer information

When planning to drive your NISSAN ve-
hicle in another country,you should first
find out if the fuel available is suitable for
your vehicle's engine.
Using fuel with an octane rating that is too
low may cause engine damage. All gaso-
line vehicles must be operated with un-
leaded gasoline. Therefore, avoid taking
your vehicle to areas where appropriate
fuel is not available.
When transferring the registration of
your vehicle to another country, state,
province or district, it may be necessary
to modif y the vehicle to meet local laws
and regulations.
The laws and regulations for motor vehicle
emission control and safety standards
vary according to the country, state, prov-
ince or district; therefore, vehicle specifica-
tions may differ.
When any vehicle is to be taken into an-
other country, state, province or district
and registered, its modifications, trans-
portation and registration are the re-
sponsibility of the user. NISSAN is not re-
sponsible for any inconvenience that
may result.

WARNING
A vehicle equipped with All -Wheel Drive
(AWD) should never be tested using a
two wheel dynamometer (such as the
dynamometers used by some states for
emissions testing), or similar equip-
ment. Make sure you inform the test fa-
cility personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drivetrain
damage or unexpected vehicle move-
ment which could result in serious ve-
hicle damage or personal injury.
Due to legal requirements in some states
and Canadian Provinces, your vehicle
may be required to be in what is called
the “ready condition” for an Inspection/
Maintenance (I/M) test of the emission
control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the ready condition can
be obtained by ordinary usage of the ve-
hicle. If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a “not ready” condi-
tion. Before taking the I/M test, check the
vehicle’s inspection/maintenance test
readiness condition. Place the ignition
switch in the ON position without starting
the engine. If the Malfunction Indicator
Light (MIL) comes on steady for 20 seconds
and then blinks for 10 seconds , the I/M test
condition is “not ready”. If the MIL does not
blink af ter 20 seconds, the I/M test condi-
tion is “ready”. It is recommended that you
visit a NISSAN dealer to set the “ready con-
dition” or to prepare the vehicle for testing.
This vehicle is equipped with an EDR. The
main purpose of an EDR is to record, in
certain collision or near collision-like situa-
tions, such as an air bag deployment or
hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems
performed. The EDR is designed to record
data related to vehicle dynamics and
safety systems for a short period of time,
typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
∙ How various systems in your vehicle were operating;
∙ Whether or not the driver and passen- ger safety belts were buckled/fastened;
∙ How far (if at all) the driver was depress- ing the accelerator and/or brake pedal;
and,
∙ How fast the vehicle was traveling.
∙ Sounds are not recorded.
