to the engine. If any of the above symptoms
are encountered, have your vehicle checked at
a NISSAN dealer or other competent service
facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
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 con-
serve 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 Pe-
troleum Institute (API) certification mark on thefront of the container should be used. This type
of oil supersedes the existing API SG or SH
and Energy Conserving II categories.
If you cannot find engine oil with the certifica-
tion mark, an API SG or SH and Energy
Conserving II oil with API service symbol may
be used. An oil with a single designation SG or
SH, or in combination with other categories
(for example, SG/CC or SG/CD) may also be
used if one with the API certification mark
cannot be found.
Mineral based or synthetic type oils may be
used in your NISSAN vehicle. These oils must
however, meet the API quality and SAE vis-

cosity ratings specified for your vehicle. Do not
mix mineral based and synthetic type oils in
the engine at the same time.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 impor-
tant that the engine oil viscosity be selected
based on the temperatures at which the ve-
hicle will be operated before the next oil
change. The recommended SAE viscosity
number chart shows the recommended oil
viscosities for the expected ambient tempera-
tures. Choosing an oil viscosity other than that
recommended could cause serious engine
damage.Selecting the correct oil filterYour new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When replac-
ing, 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 re-
duce 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 warran-
ties.
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. Op-
eration under the following conditions may
require more frequent oil and filter changes.
Irepeated short distance driving at cold out-
side temperatures,
Idriving in dusty conditions,
Iextensive idling,
Itowing a trailer.

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
must be operated with unleaded engine gaso-
line. 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 modify 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, province or
district; therefore, 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.

cargo as necessary. If either the front or
rear GAWR is exceeded, shift the load or
remove cargo as necessary.
LOADING TIPSIThe GVW must not exceed GVWR or
GAWR as specified on the F.M.V.S.S. cer-
tification label.
IDo not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.IProperly secure all cargo to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
IDo not load your vehicle any heavier
than the GVWR or the maximum front
and rear GAWRs. If you do, parts on
your vehicle can break, or it can
change the way your vehicle handles.
This could result in loss of control
and cause personal injury.
IOverloading can shorten the life ofyour 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 addi-
tional loads on your vehicle's engine, drive
train, steering, braking and other systems.
Information on trailer towing ability and the
special equipment required should be ob-
tained from your Nissan dealer. He can obtain
aNissan Trailer Towing Guidefor you.

then move the transmission selector lever
into the P (Park) position. If you move the
selector lever to the P (Park) position be-
fore blocking the wheels and applying the
parking brake, transmission damage could
occur.
IWhen 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 over-
loading and/or overheating.
IIf 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
control to high and setting the temperature
control to the HOT position.
ITrailer towing requires more fuel than nor-
mal circumstances.
IAvoid towing a trailer for the first 500 miles
(800 km).
IHave your vehicle serviced more often than
at intervals specified in the recommended
maintenance schedule.
IWhen making a turn, your trailer wheels will
be closer to the inside of the turn than yourvehicle wheels. To compensate for this,
make a larger than normal turning radius
during the turn.
ICrosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being passed
by larger vehicles, be prepared for possible
changes in crosswinds that could affect
vehicle handling. If swaying does occur,
firmly grip the steering wheel, steer straight
ahead, and immediately (but gradually) re-
duce vehicle speed. This combination will
help stabilize the vehicle. Never increase
speed.
IBe careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember the length of the trailer
must also pass the other vehicle before you
can safely change lanes.
ITo maintain engine braking efficiency and
electrical charging performance, do not use
fifth gear (manual transmission) or over-
drive (automatic transmission).
IAvoid holding the brake pedal down too
long or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.When towing a trailer, change oil in the
transmission more frequently.

what is called the ready condition for an
Inspection/Maintenance (I/M) test of the emis-
sion 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 vehicle.
If a powertrain system component is repaired
or the battery is disconnected, the vehicle may
be reset to a not ready condition. Before taking
the I/M test, drive the vehicle through the
following pattern to set the vehicle to the ready
condition. If you cannot or do not want to
perform the driving pattern, an NISSAN dealer
can conduct it for you.Always drive the vehicle in a safe man-
ner according to traffic conditions and
