Selecting the correct oil filter
Your 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 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 en-
gines 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.

When planning to travel in another coun-
try,you should first find out if the fuel
available is suitable for your vehicle's en-
gine.
Using fuel with too low an octane/cetane
rating may cause engine damage. All gaso-
line vehicles must be operated with un-
leaded engine gasoline. Therefore, avoid
taking your vehicle to areas where appropri-
ate 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.
VEHICLE IDENTIFICATION NUM-
BER PLATE
The vehicle identification number plate is

Maximum load limits
Maximum trailer loads
Never allow the total trailer load to exceed
1,000 lb (454 kg). The total trailer load
equals trailer weight plus its cargo weight.
Towing loads greater than 1,000 lb (454 kg)
or using improper towing equipment could
adversely affect vehicle handling, braking
and performance.
WARNING
Vehicle damage and/or personal injury
resulting from improper towing proce-
dures is not covered by NISSAN war-
ranties. Information on trailer towing
and required towing equipment should
be obtained from dealers who special-
ize in providing trailers or other towing
equipment.
Tongue load
Keep the tongue load between 9 and 11%
of the total trailer load. If the tongue load
becomes excessive, rearrange cargo to al-
low for proper tongue load.Maximum gross vehicle weight/maximum
gross axle weight
The gross vehicle weight of the towing
vehicle must not exceed the gross vehicle
weight rating (GVWR) shown on the
F.M.V.S.S. certification label. The gross ve-
hicle weight equals the combined weight of
the unloaded vehicle, passengers, luggage,
hitch, trailer tongue load and any other
optional equipment. In addition, front or rear
gross axle weight must not exceed the
gross axle weight rating (GAWR) shown on
the F.M.V.S.S. certification label.

Trailer hitch
Choose a proper hitch for your vehicle and
trailer. Make sure the trailer hitch is securely
attached to the vehicle to help avoid per-
sonal injury or property damage due to
sway caused by crosswinds, rough road
surfaces or passing trucks.
cAxle-mounted hitches should not be
used.
cThe hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.
cDo not modify the vehicle exhaust sys-
tem, brake system, etc. when the hitch is
installed.
cTo reduce the possibility of additional
damage if your vehicle is struck from the
rear, remove the hitch when not in use.
TI1012M
9-16
ZX

After the hitch is removed, seal the bolt
holes to prevent exhaust fumes, water
or dust from entering the passenger
compartment.
cRegularly check that all hitch mounting
bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pres-
sure indicated on the tire placard (lo-
cated on the driver side center pillar.)
cTrailer tire condition, size, load rating
and proper inflation pressure should be
in accordance with the trailer and tire
manufacturers' specifications.
Safety chain
Always use a suitable chain between your
vehicle 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 lights
Trailer lights should comply with federal
and/ or local regulations. When wiring thevehicle for towing, connect the stop and tail
light pickup into the vehicle electrical circuit.
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.
CAUTION
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
cBe 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 pos-
sible causes of either condition.
cAlways secure items in the trailer to
prevent load shifts while driving.
cBe certain your rear view mirrors con-
form to all federal, state or local regula-
tions. 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 are
somewhat different than under normal driv-
ing conditions.
cAlways secure items in the trailer to
prevent load shift while driving.
c
Avoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
c
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 park-
ing brake, and then move the transmis-
sion shift lever into the P position. If you
move the shift lever to the P position
before blocking the wheels and applying
the parking brake, transmission damage
could occur.

braking traction tests and does not
include cornering (turning) traction.
Temperature A, B and C
Temperature 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 condi-
tions on a specified indoor laboratory test
wheel. Sustained high temperature can
cause tire material to degenerate, reducing
tire life. Excessive temperatures can lead to
sudden tire failure. Grade C corresponds to
a performance level which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades A
and B represent higher levels of perfor-
mance on laboratory test wheels than the
minimum required by law.
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under inflation, or excessive
loading, either separately or in combi-
nation, can cause heat build-up and
possible tire failure problems.Your NISSAN is covered by the following
emission warranties.
