Tire pressure NISSAN 350Z 2004 Owner´s Manual

LOW TIRE PRESSURE WARNING
SYSTEM (if so equipped)The low tire pressure warning system which
displays pressure of all tires (except the spare
tire) on the trip computer by sending a signal
from a sensor that is installed in each wheel. If
the vehicle is being driven with very low tire
pressure (lower than 28 psi), the low tire pres-
sure warning system will activate and warn you
of it by the low tire pressure warning light (in the
meter panel) or the PSI indicator (on the trip
computer). This system will activate only when
the vehicle is driven at speeds above 20 MPH
(32 km/h). For more details, refer to “Trip com-
puter” and “Warning/indicator lights and audible
reminders” in the “2. Instruments and controls”
section and “Low tire pressure warning system”
in the “5. Starting and driving” section.
WARNING

If the low tire pressure warning light
comes on and/or the PSI indicator
flashes while driving, avoid sudden
steering maneuvers or abrupt brak-
ing, reduce vehicle speed, pull off the
road to a safe location and stop thevehicle as soon as possible. Serious
vehicle damage could occur and may
lead to an accident and could result
in serious personal injury. Check the
pressure for all four tires. Adjust the
tire pressure to the recommended
COLD tire pressure shown on the Tire
and Loading Information label to turn
the low tire pressure warning light
OFF. If you have a flat tire, replace it
with a spare tire as soon as possible.

When a spare tire is mounted or a
wheel is replaced, tire pressure will
not be indicated and the low tire
pressure warning system will not
function. Contact your NISSAN
dealer as soon as possible for tire
replacement and/or system reset-
ting.

Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
CHANGING A FLAT TIREIf you have a flat tire, follow the instructions
below.Stopping the vehicle1. Safely move the vehicle off the road away
from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking
brake. Shift the manual transmission into R
(Reverse) position (automatic transmission in
P (Park) position).
4. Turn off the engine.
5. Raise the hood to warn other traffic, and to
signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle
and stand in a safe place, away from traffic
and clear of the vehicle.
WARNING

Make sure that the parking brake is
securely applied and the manual
transmission is shifted into R (Re-

verse), or the automatic transmission
into P (Park).

Never change tires when the vehicle
is on a slope, ice or slippery areas.
This is hazardous.

Never change tires if oncoming traffic
is close to your vehicle. Wait for pro-
fessional road assistance.

When a spare tire is mounted or a
wheel is replaced, tire pressure will
not be indicated and the low tire
pressure warning system will not
function. Contact your NISSAN
dealer as soon as possible for tire
replacement and/or system reset-
ting. (For models with the low tire
pressure warning system)
Blocking wheelsPlace suitable blocks at both the front and back
of the wheel diagonally opposite the flat tire to
prevent the vehicle from moving when it is jacked
up.
WARNING
Be sure to block the wheel as the ve-
hicle may move and could cause per-
sonal injury.
Getting the spare tire and toolsRemove spare tire and jacking tools from the
storage area located in the luggage/trunk as
illustrated.
Coupe models:
1. Spare tire — Turn the retainer counterclock-
wise to remove.
2. Jack — Turn it counterclockwise to remove.

Installing the spare tireThe spare tire is designed for emergency
use. See specific instructions under the
heading “Wheels and tires” in the “8. Main-
tenance and do-it-yourself” section.
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the wheel on and tighten the
wheel nuts finger tight. When replacing a
front tire, make sure the hole in the spare tire
wheel is aligned with the pin on the brake
rotor.
3. With the wheel nut wrench, tighten wheelnuts alternately and evenly in the sequence
illustrated (
1
-5) until they are tight.
4. Lower the vehicle slowly until the tire touches
the ground. Then, with the wheel nut wrench,
tighten the wheel nuts securely in the se-
quence as illustrated. Lower the vehicle com-
pletely.
WARNING

Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.

Do not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.

Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
As soon as possible tighten the wheel nuts
to the specified torque with a torque
wrench.Wheel nut tightening torque:
80 ft-lb (108 N⋅m)
The wheel nuts must be kept tightened to
specification at all times. It is recom-
mended that wheel nuts be tightened to
specification at each lubrication interval.
Adjust tire pressure to the COLD pressure.
COLD pressure:
After vehicle has been parked for three
hours or more or driven less than 1 mile
(1.6 km).
COLD tire pressures are shown on the Tire
and Loading Information label affixed to
the driver’s side center pillar.
For models equipped with the low tire
pressure warning system:
After adjusting tire pressure to the COLD tire
pressure, the display of the tire pressure infor-
mation may show higher pressure than the
COLD tire pressure after the vehicle has been
driven more than 1 mile (1.6 km). This is because
the tire pressurizes as the tire temperature rises.
This does not indicate a system malfunction.
Stowing the tire and toolsSecurely store the spare tire and jacking equip-
ment in the vehicle.

Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)*:When checking
the tires, make sure no nuts are missing, and
check for any loose nuts. Tighten if necessary.
Tire rotation*:Tires cannot be rotated in this
vehicle.
Tire, wheel alignment and balance:If the
vehicle pulls to either side while driving on a
straight and level road, or if you detect uneven or
abnormal tire wear, there may be a need for
wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer to
“Important Tire Safety Information” (US) or “Tire
Safety Information” (Canada) in the Warranty
Information Booklet.
Tires*:Check the pressure with a gauge often
and always prior to long distance trips. Adjust
the pressure in all tires, including the spare, to
the pressure specified. Check carefully for dam-age, cuts or excessive wear.
Windshield:Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified re-
pair facility.
Windshield wiper blades*:Check for cracks
or wear if they do not wipe properly.
Inside the vehicleThe maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the

TIRE PRESSURE
Tire inflation pressureCheck the pressure of the tires (including the
spare) often and always prior to long distance
trips. The recommended tire pressure specifica-
tions are shown on the Tire and Loading Infor-
mation label under the “Recommended Cold
Tire Inflation Pressure” heading. The Tire and
Loading Information label is affixed to the driver
side center pillar. Tire pressures should be
checked regularly because:

Most tires naturally lose air over time.

Tires can lose air suddenly when driven over
potholes or other objects or if the vehicle
strikes a curbwhile parking.
The tire pressures should be checked when the
tires are cold. The tires are considered COLD
after the vehicle has been parked for 3 or more
hours, or driven less than 1 mile (1.6 km) at
moderate speeds.
Incorrect tire pressure, including under in-
flation, may adversely affect tire life and
vehicle handling.
WARNING

Improperly inflated tires can fail sud-
denly and cause an accident.

The vehicle capacity weight is indi-
cated on the Tire and Loading Infor-
mation label. Do not load your ve-
hicle beyond this capacity.
Overloading your vehicle may result
in reduced tire life, unsafe operating
conditions due to premature tire mal-
function, or unfavorable handling
characteristics and could also lead to
a serious accident. Loading beyond
the specified capacity may also result
in a malfunction of other vehicle
components.

Before taking a long trip, or when-
ever you heavily load your vehicle,
use a tire pressure gauge to ensure
that the tire pressures are at the
specified level.

Do not drive your vehicle over 85
MPH (137 km/h) unless it is equipped
with high-speed rated tires. Drivingfaster than 85 MPH (137 km/h) may
result in tire failure, loss of control
and possible injury.

For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Low tire pressure warning system (if
so equipped)The low tire pressure warning system displays
the tire pressure of all tires (except the spare tire)
on the trip computer by sending a signal from a
sensor that is installed in each wheel. For more
details, refer to “Trip computer” and “Low tire
pressure warning light” in the “2. Instruments
and controls” section, “Low tire pressure warn-
ing system” in the “5. Starting and driving”
section, and “Flat tire” in the “6. In case of
emergency” section. If the tire pressure dis-
played on the trip computer is lower than the
COLD tire pressure shown on the Tire and
Loading Information label, check the pressure of
all four tires and adjust them to the COLD tire
pressure. The low tire pressure warning system
will activate only when the vehicle is driven at
speeds above 20 MPH (32 km/h).

Checking the tire pressure1. Remove the valve stem cap from the tire.
2. Press the pressure gauge squarely onto the
valve stem. Do not press too hard or force the
valve stem sideways, or air will escape. If the
hissing sound of air escaping from the tire is
heard while checking the pressure, reposition
the gauge to eliminate this leakage.
3. Remove the gauge.
4. Read the tire pressure on the gauge stem
and compare it to the specification shown on
the Tire and Loading Information label.
5. Add air to the tire as needed. If too much air

is added, press the core of the valve stem
briefly with the tip of the gauge stem to
release pressure. Recheck the pressure and
add or release air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, includ-
ing the spare.
TIRE LABELINGFederal law requires tire manufacturers to place
standardized information on the sidewall of all
tires. This information identifies and describes
the fundamental characteristics of the tire and
also provides the tire identification number (TIN)
for safety standard certification. The TIN can be
used to identify the tire in case of a recall.
1Tire size (example: P215/60R16 94H)
P: The “P” indicates the tire is designed for
passenger vehicles. (Not all tires have this
information.)
Three-digit number (215): This number gives
the width in millimeters of the tire from side-
wall edge to sidewall edge.
1st two-digit number (60): This number,
known as the aspect ratio, gives the tire’s
ratio of height to width.
R: The “R” stands for radial.
2nd two-digit number (16): This number is
the wheel or rim diameter in inches.3rd two- or three-digit number (94): This
number is the tire’s load index. It is a mea-
surement of how much weight each tire can
support. (You may not find this information on
all tires because it is not required by law.)
H: Tire Speed Rating. The speed rating de-
notes the speed at which a tire is designed to
be driven for extended periods of time. The
ratings range from 98 MPH (miles per hour)
to 186 MPH. (You may not find this informa-
tion on all tires because it is not required by
law.)
2TIN (Tire Identification Number) for new tire
(example: DOT XX XX XXX XXXX)
DOT: Abbreviation for the “Department of
Transportation”. The symbol can be
placed above, below or to the left or
right of the Tire Identification Number.
1st two-digit code: Manufacturer’s identifica-
tion mark
2nd two-digit code: Tire size
3rd three-digit code: Tire type code (Op-
tional)
4th three-digit code: Date of Manufacture
Four numbers represent the week and year
the tire was built. For example, the numbers
3103 means the 31st week of 2003.

3Tire ply composition and material
The number of layers or plies of rubber-
coated fabric in the tire.
Tire manufacturers also must indicate the
materials in the tire, which include steel,
nylon, polyester, and others.
4Maximum permissible inflation pressure
This number is the greatest amount of air
pressure that should be put in the tire. Do not
exceed the maximum permissible inflation
pressure.
5Maximum load rating
This number indicates the maximum load in
kilograms and pounds that can be carried by
the tire. When replacing the tires on the
vehicle, always use a tire that has the same
load rating as the factory installed tire.
6Term of “tubeless” or “tube type”
Indicates that the tire requires an inner tube
(“tube type”) or not (“tubeless”).
7The word “radial”
The word “radial” is shown, if the tire has a
radial structure.
8Manufacturer or Brand name
Manufacturer or Brand name is shown.
Other tire-related terminologyIn addition to the many terms that are definedthroughout this section, Intended Outboard
Sidewall is (1) the sidewall that contains a
whitewall, bears white lettering or bears manu-
facturer, brand, and/or model name molding that
is higher or deeper than the same molding on the
other sidewall of the tire, or (2) the outward
racing sidewall of an asymmetrical tire that has a
particular side that must always face outward
when mounted on a vehicle.
TYPES OF TIRES
WARNING

When changing or replacing tires, be
sure all four tires are of the same
type (for example, summer, all sea-
son or snow) and construction. Your
NISSAN dealer may be able to help
you with information about tire type,
size, speed rating and availability.

Replacement tires may have a lower
speed rating than the factory
equipped tires, and may not match
the potential maximum vehicle
speed. Never exceed the maximum
speed rating of the tire.
For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
All season tiresNISSAN specifies all season tires on some
models to provide good performance for use all
year round, including snowy and icy road condi-
tions. All season tires are identified by ALL
SEASON and/or M&S on the tire sidewall. Snow
tires have better snow traction than all season
tires and may be more appropriate in some
areas.Summer tiresNISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance in snow and ice will be
substantially reduced. Summer tires do not have
the tire traction rating M&S on the tire sidewall.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
snow or all season tires on all four wheels.

Tire wear and damage
WARNING

Tires should be periodically in-
spected for wear, cracking, bulging,
or objects caught in the tread. If ex-
cessive wear, cracks, bulging, or
deep cuts are found, the tire should
be replaced.

The original tires have a built-in tread
wear indicator. When the wearindicator is visible, the tire should be
replaced.

Improper service for a spare tire may
result in serious personal injury. If it
is necessary to repair the spare tire,
contact your NISSAN dealer.

For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tiresWhen replacing a tire, use the same size, speed
rating and load carrying capacity as originally
equipped. See “Specifications” in the “9. Tech-
nical and consumer information” section for rec-
ommended types and sizes of tires and wheels.
WARNING

The use of tires other than those
recommended 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.

If 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.

When a spare tire is mounted or a
wheel is replaced, tire pressure will
not be indicated and the low tire
pressure warning system will not
function. Contact your NISSAN
dealer as soon as possible for tire
