engine NISSAN 350Z 2005 Owner´s Manual

If any undesirable driveability problems such as
engine stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels, imme-
diately change to a non-oxygenate fuel or a fuel
with a low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.Aftermarket fuel additivesNISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel in-
jector cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for gum,
varnish or deposit removal may contain active
solvents or similar ingredients that can be harm-
ful to the fuel system and engine.Octane rating tipsUsing unleaded gasoline with an octane
rating lower than recommended 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 above stated
octane rating, or if you hear steady spark
knock while holding a steady speed on
level roads, have your dealer correct thecondition. 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 en-
countered, have your vehicle checked at a
NISSAN dealer or other competent service fa-
cility.
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

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 on the 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 certifi-
cation mark, use an API grade SG/SH, Energy
ConservingI&IIorAPIgrade SJ or SL, 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 &
GF-III oil can also be used.NISSAN recommends mineral based oils. These
oils 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 “Rec-
ommended SAE viscosity number” chart (on the
next page) shows the recommended oil viscosi-
ties for the expected ambient temperatures.
Choosing an oil viscosity other than that recom-
mended could cause serious engine damage.Selecting the correct oil filterYour 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 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,

stop and go “rush hour” traffic.
RECOMMENDED SAE VISCOSITY
NUMBERSAE 5W-30 viscosity oil is preferred for all
ambient temperatures. SAE 10W-30 or
10W-40 viscosity oil may be used if the
ambient temperature is above 0°F (−18°C).
AIR CONDITIONER SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONSThe air conditioner system in your 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 governmental
regulations require the recovery and recycling of
any refrigerant during automotive air conditioner
system service. A NISSAN dealer has the trained
technicians and equipment needed to recover
and recycle your air conditioner system refriger-
ant.

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 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

WARNING

Properly 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.

Do not load your vehicle any heavier
than the GVWR or the maximum front
and rear GAWRs. If you do, parts of
your vehicle can break, tire damage
could occur, or it can change the way
your vehicle handles. This could re-
sult in loss of control and cause per-
sonal injury.

Overloading not only could shorten
the life of your vehicle and the tires,
but also could lead to unsafe vehicle
handling and long braking distance.
This could cause a premature tire
malfunction, which could result in a
serious accident and personal injury.
Failures caused by overloading are
not covered by the vehicle’s warranty.Roadster model:
Do not tow a trailer with your vehicle.
Coupe model:
Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer places additional
loads on your vehicle’s engine, drive train, steer-
ing, braking and other systems.
ANISSAN Trailer Towing Guide(US only) is
available from a NISSAN dealer. This guide
includes information on trailer towing ability and
the special equipment required for proper tow-
ing.
WARNING
Overloading or improper loading of a
trailer and its cargo can adversely affect
vehicle handling, braking and perfor-
mance and may lead to accidents.
CAUTION

Do not tow a trailer or haul a heavy
load for the first 500 miles (800 km).
Your engine, axle or other parts
could be damaged.

For the first 500 miles (800 km) that
you tow a trailer, do not drive over 50
mph (80 km/h) and do not make
starts at full throttle. This helps the
engine and other parts of your ve-
hicle wear in at the heavier loads.MAXIMUM LOAD LIMITS
Maximum trailer loadsNever allow the total trailer load to exceed 1,000
lb(454 kg). The total trailer load equals trailer

the proper equipment and to have it
installed.
Trailer lights should comply with federal and/or
local regulations. When wiring the vehicle for
towing, connect the stop and tail light pickup
into the vehicle electrical circuit at a point be-
tween the sensor and stop light 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.Pre-towing tips
Be certain a vehicle maintains a level position
when a loaded and/or unloaded trailer is
hitched. Do not drive the vehicle if it has an
unusual nose-up or nose-down condition;
check for improper tongue load, overload,
worn suspension or other possible causes of
these conditions.
Always secure items in the trailer to prevent
load shifts while driving.

Load the trailer so approximately 60% of the
trailer load is in the front half and 40% is in
the back half.

Check your hitch, trailer tire pressure, vehicle
tire pressure, trailer light operation, and trailer
wheel lug nuts every time you attach a trailer
to the vehicle.

Be certain your rear view mirrors conform to
all federal, state and/or local regulations. If
not, install any mirrors required for towing
before 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 per-
formance 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 a vehicle at a moderate speed.
Some states or provinces have specificspeed limits for vehicles that are towing
trailers. Obey the local speed limits.

When backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and back
up slowly. If possible, have someone guide
you when you are backing up.

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 a vehicle is equipped with automatic
transmission, first apply the parking brake
and block the wheels, and then move the
transmission selector lever into the P (Park)
position. If you move the selector lever to the
P (Park) position before blocking the wheels
and applying the parking brake, the transmis-
sion may get damaged.

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

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 consumes more fuel than nor-
mal circumstances.

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

Have a vehicle serviced more often than at
intervals specified in the recommended main-
tenance schedule.

When 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.

Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling. If swaying does occur, firmly
grip the steering wheel, steer straight ahead,
and immediately (but gradually) reduce ve-
hicle speed. This combination will help stabi-
lize the vehicle. Never increase speed.

Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal passing.Remember the length of the trailer must also
pass the other vehicle before you can safely
change lanes.

To maintain engine braking efficiency and
electrical charging performance, do not use
6th gear (manual transmission) or 5th posi-
tion (automatic transmission).

Avoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking ef-
ficiency.

Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.

Do not use cruise control while towing a
trailer.

Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.

When stopped in traffic for long periods of
time in hot weather, put the vehicle in the P
(Park) position.
When towing a trailer, change transmis-
sion oil more frequently. For additional
information, see the “8. Maintenance and
do-it-yourself” section.Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a ve-
hicle behind a recreational vehicle, such as a
motor home.
CAUTION

Failure to follow these guidelines
can result in severe transmission
damage.

Whenever flat towing your vehicle,
always tow forward, never backward.

DO NOT tow any automatic transmis-
sion vehicle with all four wheels on
the ground (flat towing). Doing so
WILL DAMAGE internal transmission
parts due to lack of transmission lu-
brication.

For emergency towing procedures,
refer to “Towing recommended by
NISSAN” in the “6. In case of emer-
gency” section of this manual.FLAT TOWING

AUTOMATIC TRANSMISSIONTo tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dollyMUST
be placed under the towed vehicle’s drive
wheels.Alwaysfollow the dolly manufacturer’s
recommendations when using their product.MANUAL TRANSMISSION
Always tow with the manual transmission in
Neutral.

After towing 500 miles, start and idle the
engine with the transmission in Neutral for
two minutes. Failure to idle the engine after
every 500 miles of towing may cause damage
to internal transmission parts.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. How-
ever, relative tire performance depends on actual
driving conditions, and may vary significantly
from the norm due to variations in driving habits,
service practices and differences in road char-
acteristics 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 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.
