tion booklet (Canada).
Replacing wheels and tiresWhen replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. See ªSpecificationsº in the
ª9. Technical and consumer informationº sec-
tion for recommended types and sizes of tires
and wheels.
WARNING
IThe use of tires other than thoserecommended or the mixed use of
tires of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.
IIf the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offset
could cause early tire wear, possibly
degraded vehicle handling character-
istics and/or interference with the
brake discs. Such interference can
lead to decreased braking efficiency
and/or early brake pad wear.
IDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-ing.
IThe use of retread tire is not recom-
mended.
IFor additional information regarding
tires, refer to ªImportant Tire Safety
Informationº in the Warranty Informa-
tion Booklet (US) or ªTire Safety In-
formationº in the Warranty Informa-
tion booklet (Canada).
Wheel balanceUnbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore, they
should be balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balancing
the front wheels on the vehicle could lead to
transmission damage.
For additional information regarding tires, refer
to ªImportant Tire Safety Informationº in the
Warranty Information Booklet (US) or ªTire
Safety Informationº in the Warranty Informa-
tion booklet (Canada).

unleaded gasoline with an octane rating of at
least 87 or 91 AKI (Anti-Knock Index) number.
However, you may use unleaded gasoline with
an octane rating as low as 85 AKI number in
these high altitude areas [over 4,000 ft (1,219
m)] such as: Colorado, Montana, New Mexico,
Utah, Wyoming, northeastern Nevada, south-
ern Idaho, western South Dakota, western
Nebraska, and that part of Texas which is
directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, have your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may
cause excessive fuel consumption or damage
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.9-4

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.
RECOMMENDED SAE VISCOSITY
NUMBERSAE 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 0ÉF (þ18ÉC).
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 refrigerant or lubri-
cant will cause severe damage to the air
conditioning system and will require the
replacement of all air conditioner sys-
tem 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 govern-
mental regulations require the recovery and
recycling of any refrigerant during automotive
air conditioning system service. Your NISSAN
dealer has the trained technicians and equip-
ment needed to recover and recycle your air
conditioning system refrigerant.

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.
IAlways secure items in the trailer to prevent
load shifts while driving.
IBe certain your rear view mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing be-
fore driving the vehicle.
Trailer towing tipsIn order to gain skill and an understanding of
the vehicle's behavior, you should practice
turning, stopping and backing up in an area
which is free from traffic. Steering stability, and
braking performance will be somewhat differ-
ent than under normal driving conditions.
IAlways secure items in the trailer to prevent
load shift while driving.
IAvoid abrupt starts, acceleration or stops.
IAvoid sharp turns or lane changes.
IAlways drive your vehicle at a moderate
speed.
IAlways block the wheels on both vehicle
and trailer when parking. Parking on aslope 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 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 thanat intervals specified in the recommended
maintenance schedule.
IWhen 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.
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).9-18

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. See the
ªService and Maintenance Guideº.DOT (Department Of Transportation) Quality
Grades: All passenger car tires 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
and maximum 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. However, relative tire performance de-
pends on actual driving conditions, and may
vary significantly from the norm due to varia-
tions in driving habits, service practices and
differences in road characteristics and climate.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
measured under controlled conditions on
specified government test surfaces of asphaltand concrete. 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
specified indoor laboratory test wheel. Sus-
tained high temperature can cause tire mate-
rial 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
performance on laboratory test wheels than
the minimum required by law.
