2002 NISSAN XTERRA engine

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 de-
scribed 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. Oil and filter other
than the specified quality, or oil and filter
change intervals longer than recommended
could reduce engine life. Damage to the
engine 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 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:Ð repeated short distance driving at cold
outside temperatures,
Ð driving in dusty conditions,
Ð extensive idling,
Ð towing a trailer.
RECOMMENDED SAE
VISCOSITY NUMBER
OSAE 5W-30 viscosity oil is preferred
for all temperatures. SAE 10W-30, SAE
10W-40 viscosity oils may be used if
the ambient temperature is above 0ÉF
(-18ÉC).

When planning to drive your NISSAN
vehicle 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 driving your vehicle in ar-
eas 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
another country, state, province or dis-
trict and registered, its modifications,
transportation and registration are the
responsibility of the user. NISSAN is not
responsible for any inconvenience that
may result.

MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight shifts
that could affect the balance of your vehicle.
When the vehicle is loaded, drive to a scale
and weigh the front and the rear wheels
separately to determine axle loads. Indi-
vidual axle loads should not exceed either
of the gross axle weight ratings (GAWR).
The total of the axle loads should not ex-
ceed 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.
Your new vehicle was designed to be used
primarily to carry passengers and cargo.
Remember that towing a trailer will place
additional loads on your vehicle's engine,
drive train, steering, braking and other sys-
tems.
ANissan Trailer Towing Guide (U.S. only)
is available from an authorized NISSAN
dealer. This guide includes information on
trailer towing ability and the special equip-
ment required for proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed the
value specified in the following Towing
Load/Specification Chart. The total trailer load
equals trailer weight plus its cargo weight.
OWhen towing a trailer load of 1,000 lbs.
(454 kg) or more, trailers with a brake
system MUST be used.
The maximum GCWR (Gross Combined
Weight Rating) should not exceed the value
specified in the following Towing Load/
Specification Chart.
The GCWR equals the combined weight of
the towing vehicle (including passengers
and cargo) plus the total trailer load. Towing
loads greater than these or using improper
towing equipment could adversely affect
vehicle handling, braking and performance.
The ability of your vehicle to tow a trailer is
not only related to the maximum trailer
loads, but also the places you plan to tow.
Tow weights appropriate for level highway
driving may have to be reduced on very
steep grades or in low traction situations (for
example, on slippery boat ramps).

4) Connect the tow harness connector
(SAE J1239) to your trailer.
5) Confirm proper vehicle and trailer
stop/turn lamp operation.
6) When towing is completed, disconnect
the tow harness from the trailer and the
vehicle. Store the tow harness in the
glove box. Reinstall the connector cap to
the vehicle harness.
If you need further assistance in wiring
a trailer to your NISSAN, contact an autho-
rized NISSAN dealer.
Always confirm proper vehicle and
trailer stop/turn lamp operation every
time the trailer light circuits are con-
nected for use.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to Federal
and/or local regulations and that it is prop-
erly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
OBe certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle
if it has an abnormal nose-up or nose-
down condition; check for improper
tongue load, overload, worn suspension
or other possible causes of either condi-
tion.
OAlways secure items in the trailer to
prevent load shift while driving.
OBe certain your outside mirrors conform
to all federal, state or local regulations. If
not, install any mirrors required for towing
before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability and braking performance will be
somewhat different than under normal driv-
ing conditions.
OAlways secure items in the trailer to
prevent load shift while driving.
O
Avoid abrupt starts, acceleration or stops.
OAvoid sharp turns or lane changes.
OAlways drive your vehicle at a moderate
speed.
OAlways 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 park-
ing brake, and then move the transmis-
sion shift selector lever into the P (Park)
position. If you move the shift lever to the
P (Park) position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
OWhen 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 en-
gine overloading and/or overheating.
However, for long steep grades, do not
stay in 1st or 2nd gear when driving
above 35 MPH (56 km/h).
OIf the engine coolant rises to an ex-
tremely high temperature when the air
conditioning system is on, turn off the air
conditioner. Coolant heat can be addi-

tionally vented by opening the windows,
switching the fan control to high and
setting the temperature control to the
HOT position.
OTrailer towing requires more fuel than
normal circumstances.
OAvoid towing a trailer for your vehicle's
first 500 miles (805 km).
OHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
OWhen making a turn, your trailer wheels
will be closer to the inside of the turn than
your vehicle wheels. To compensate for
this, make a larger than normal turning
radius during the turn.
OCrosswinds and rough roads 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 immedi-
ately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.OBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
OTo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
or overdrive (automatic transmission).
OAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change oil in the
transmission more frequently. For addi-
tional information see the ``Maintenance
and do-it-yourself'' section earlier in this
manual.DOT (Department of Transportation) Quality
Grades: All passenger car tires must con-
form to Federal Safety Requirements in
addition to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified govern-
ment 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. However, rela-
tive tire performance depends on actual
driving conditions, and may vary signifi-
cantly due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction AA, A, B and C
The traction grades from highest to lowest
are AA, A, B, and C. Those grades repre-
sent the tire's ability to stop on wet pave-
