ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oilIt is essential to choose the correct quality, and
viscosity oil to ensure satisfactory engine life and
performance. Nissan recommends the use of a
low friction oil (energy conserving oil) in order to
improve fuel economy and conserve energy. Oils
which do not have the specified quality label
should not be used as they could cause engine
damage.
Only those engine oils with the American Petro-
leum Institute (API) CERTIFICATION MARK onthe front of the container should be used. This
type of oil supersedes the existing API SG, SH,
or SJ and Energy ConservingI&IIcategories.
If you cannot find engine oil with the API CER-
TIFICATION MARK, use an API grade SG/SH,
Energy ConservingI&IIorAPIgrade SJ, Energy
Conserving oil. An oil with a single designation
SG or SH, or in combination with other catego-
ries (for example, SG/CC or SG/CD) may also
be used if one with the API CERTIFICATION
MARK cannot be found. An ILSAC grade GF-I &
GF-II oil can also be used.
NISSAN does not recommend synthetic type
oils but recommends mineral based oils. Theseoils must however, meet the API quality and SAE
viscosity ratings specified for your vehicle.
Oil additivesNISSAN 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 viscosityThe engine oil viscosity or thickness changes
with temperature. Because of this, it is important
that the engine oil viscosity be selected based
on the temperatures at which the vehicle will be
operated before the next oil change. The chart
recommended SAE viscosity number shows the
recommended oil viscosities for the expected
ambient temperatures. Choosing an oil viscosity
other than that recommended could cause seri-
ous engine damage.Selecting the correct oil filterYour new vehicle is equipped with a high-quality
genuine Nissan oil filter. When replacing, use the
genuine oil filter or its equivalent for the reason
described in change intervals.

Change intervalsThe oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Oil and filter other than the
specified quality, or oil and filter change intervals
longer than recommended could reduce engine
life. Damage to engines caused by improper
maintenance or use of incorrect oil and filter
quality and/or viscosity is not covered by the
new Nissan vehicle warranties.
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 recommended change
interval. Oil and filter change intervals depend
upon how you use your vehicle. Operation under
the following conditions may require more fre-
quent oil and filter changes.
— repeated short distance driving at cold out-
side temperatures,
— driving in dusty conditions,
— extensive idling,
— towing a trailer.
RECOMMENDED SAE OIL
VISCOSITY NUMBER
SAE 5W-30 viscosity oil is preferred for all
ambient temperatures. SAE 10W-30,
10W-40 viscosity oil may be used if the
ambient temperature is above 0°F (−18°C).AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONSThe air conditioning system in this NISSAN
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and the lubricant,
Nissan A/C System Oil Type S or the exact
equivalents.
CAUTION
The use of any other refrigerants or
lubricants will cause severe damage to
the air conditioning system and will re-
quire the replacement of all air condi-
tioning system components.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle will not harm the earth’s ozone
layer. Although this refrigerant does not affect
the earth’s atmosphere, certain governmental
regulations require the recovery and recycling of
any refrigerant during automotive air condition-

When planning to travel in another country,
you should first find out if the fuel available is
suitable for your vehicle’s engine.
Using fuel with too low an octane rating
may cause engine damage. All gasoline
vehicles can be operated with unleaded
gasoline. Therefore, avoid taking your ve-
hicle 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 modify the
vehicle to meet local laws and regulations.
The laws and regulations for motor vehicle emis-
sion control and safety standards vary according
to the country, state, province or district; there-
fore, vehicle specifications may differ.
When any vehicle is to be taken into an-
other country, state, province or district
and registered, its modifications, transpor-
tation and registration are the responsibil-
ity of the user. NISSAN is not responsible
for any inconvenience that may result.

PAYLOAD WEIGHT CAPACITYThe payload weight capacity is the maximum
total weight of passengers, optional equipment
(air conditioning, trailer hitch, etc.) and cargo
that your vehicle is designed to carry.
Before driving a loaded vehicle, confirm that you
do not exceed the Gross Vehicle Weight Rating
(GVWR) or the Gross Axle Weight Rating
(GAWR) for your vehicle. See “Vehicle loading
information” earlier in this section for details.
Also check tires for proper inflation pressures.
See the tire placard affixed to the glove box lid.

MEASUREMENT OF WEIGHTSSecure loose items to prevent weight shifts that
could affect the balance of your vehicle. When
the vehicle is loaded, drive to a scale and weight
the front and the rear wheels separately to
determine axle loads. Individual axle loads
should not exceed either of the gross axle weight
ratings (GAWR). The total of the axle loads
should not exceed the gross vehicle weight
rating (GVWR). These ratings are given on the
vehicle certification label that is located on the
driver’s door lock pillar. If weight ratings are
exceeded, move or remove items to bring all
weights below the ratings.
CAUTION
Overloading can shorten the life of your
vehicle. Failures caused by overloading
are not covered by your warranty.Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer will place additional
loads on your vehicle’s engine, drive train, steer-
ing, braking and other systems.
ANissan Trailer Towing Guide (US only)is
available from an authorized NISSAN dealer.
This guide includes information on trailer towing
ability and the special equipment required for
proper towing.

After the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.

Regularly check all hitch mounting
bolts are securely mounted.

To reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch and/or receiver
when not in use.

Never connect a trailer brake system
directly to the vehicle brake system.Tire pressures
When towing a trailer, inflate the vehicle tires
to the recommended cold tire pressure indi-
cated on the tire placard (affixed to the glove
box lid).

Trailer tire condition, size, load rating and
proper inflation pressure should be in accor-
dance with the trailer and tire manufacturers’
specifications.Safety chains
Always use a suitable chain between your ve-
hicle and the trailer. The chain should be
crossed and should be attached to the hitch, not
to the vehicle bumper or axle. Be sure to leave
enough slack in the chain to permit turning
corners.Trailer lightsTrailer lights should comply with Federal and/or
local regulations.
When wiring vehicle for towing connection,
connect stop and tail light pickup into the
vehicle electrical circuit at point between
the sensor and stop light switch or light
switch.Trailer brakesIf your trailer is equipped with a braking system,
make sure it conforms to Federal and/or local
regulations and that it is properly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.Trailer towing tipsIn order to gain skill and an understanding of thevehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability and braking perfor-
mance will be somewhat different than under
normal driving conditions.

Always secure items in the trailer to prevent
load shift while driving.

Avoid abrupt starts, acceleration or stops.

Avoid sharp turns or lane changes.

Always drive your vehicle at a moderate
speed.

Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so,
and if your vehicle is equipped with automatic
transmission, first block the wheels and apply
the parking brake, and then move the trans-
mission selector lever into the P position. If
you move the selector lever to the P position
before blocking the wheels and applying the
parking brake, transmission damage could
occur.

When going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine overload-
ing and/or overheating.

However, for long steep grades, do not stay in
1st or 2nd gear when driving above 35 MPH (56
km/h).

If the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan con-
trol to high and setting the temperature con-
trol to the HOT position.

Trailer towing requires more fuel than normal
circumstances.

Avoid towing a trailer for the first 500 miles
(800 km).

Have your vehicle serviced more often than at
intervals specified in the recommended Main-
tenance Schedule.
When towing a trailer, change oil in the
transmission more frequently. See the
Maintenance Schedule.UNIFORM TIRE QUALITY GRADINGDOT (Department of Transportation) Quality
Grades: All passenger car tire must conform to
Federal Safety Requirements in addition to these
grades.
Quality grades can be found where applicable
on the tire sidewall between tread shoulder andmaximum section width. For example:
Treadwear 200 Traction AA Temperature A
TreadwearTreadwear grade is a comparative rating based
on tire wear rate when tested under controlled
conditions on specified government test
courses. For example, a tire graded 150 would
wear one and a half (1-1/2) times as well on the
government course as a tire graded 100. How-
ever, relative tire performance depends on actual
driving conditions, and may vary significantly due
to variations in driving habits, service practices
and differences in road characteristics and cli-
mate.Traction AA, A, B and CThe traction grades from highest to lowest are
AA, A, B, and C. Those grades represent the
tire’s ability to stop on wet pavement as mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests, and does not in-
clude acceleration, cornering, hydro-
planing, or peak traction characteristics.Temperature A, B and CTemperature grades are A (the highest), B, and
C. They represent a tire’s resistance to heat
build-up, and its ability to dissipate heat when
tested under controlled conditions on a speci-
fied indoor laboratory test wheel. Sustained high
temperature can cause tire material to degener-
ate, reducing tire life. Excessive temperatures
can lead to sudden tire failure. Grade C corre-
sponds to a performance level which all passen-
ger car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades A and
B represent higher levels of performance on
laboratory test wheels than the minimum re-
quired by law.Technical and consumer information
