ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality and viscosity engine oil to ensure
satisfactory engine life and performance.
For additional information, refer to “Recom-
mended fluids/lubricants and capacities”
in this section. NISSAN recommends the
use of an energy conserving oil in order to
improve fuel economy.Select only engine oils that meet the
American Petroleum Institute (API) certifi-
cation or International Lubricant Standard-
ization and Approval Committee (ILSAC)
certification and SAE viscosity standard.
These oils have the API certification mark
on the front of the container. Oils which do
not have the specified quality label should
not be used as they could cause engine
damage.
Oil additives
NISSAN does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or
has been previously used should not be
used.
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.”
LTI2051

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.

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
• It is extremely dangerous to
ride in a cargo area inside a ve-
hicle. In a collision, people rid-
ing in these areas are more
likely to be seriously injured or
killed.
• Do not allow people to ride in
any area of your vehicle that is
not equipped with seats and
seat belts.
• Be sure everyone in your ve-
hicle is in a seat and using a
seat belt properly.
TERMS
It is important to familiarize yourself
with the following terms before
loading your vehicle: • Curb Weight (actual weight of your
vehicle) - vehicle weight including:
standard parts, fluids, emergency
tools and spare tire assembly. This
weight does not include passen-
gers and cargo.
• GVW (Gross Vehicle Weight) - curb weight plus the combined weight
of passengers and cargo.
• GVWR (Gross Vehicle Weight Rat- ing) - maximum total combined
weight of the unloaded vehicle,
passengers, luggage, hitch, trailer
tongue load and any other op-
tional equipment. This information
is located on the F.M.V.S.S./
C.M.V.S.S. certification label.
• GAWR (Gross Axle Weight Rating) - maximum weight (load) limit
specified for the front or rear axle.
This information is located on the
F.M.V.S.S./C.M.V.S.S. certification la-
bel. • GCWR (Gross Combined Weight
Rating) - The maximum total
weight rating of the vehicle, pas-
sengers, cargo, and trailer.
• Vehicle Capacity Weight, Load limit, Total load capacity - maximum to-
tal weight limit specified of the load
(passengers and cargo) for the ve-
hicle. This is the maximum com-
bined weight of occupants and
cargo that can be loaded into the
vehicle. If the vehicle is used to tow
a trailer, the trailer tongue weight
must be included as part of the
cargo load. This information is lo-
cated on the Tire and Loading In-
formation label.
• Cargo capacity - permissible weight of cargo, the subtracted
weight of occupants from the load
limit.
VEHICLE LOADING INFORMATION
Technical and consumer information10-15

VEHICLE LOAD CAPACITY
Do not exceed the load limit of your
vehicle shown as “The combined
weight of occupants and cargo” on
the Tire and Loading Information la-
bel. Do not exceed the number of
occupants shown as “Seating Ca-
pacity” on the Tire and Loading Infor-
mation label.
To get “the combined weight of oc-
cupants and cargo”, add the weight
of all occupants, then add the total
luggage weight. Examples are
shown in the following illustration.
