2005 NISSAN 350Z inflation pressure

immediatelyand call a NISSAN dealer or other
authorized repair shop.
The engine oil pressure warning light is not
designed to indicate a low oil level. Use the
dipstick to check the oil level.See “Engine
oil” in the “8. Maintenance and do-it-yourself”
section.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Turn off the engine as
soon as it is safe to do so.
Low tire pressure warning light
After the ignition switch is turned ON, this light
comes on for about 1 second and turns off.
This light warns of low tire pressure.
NISSAN’s low tire pressure warning system is a
tire pressure monitoring system. It monitors tire
pressure of all tires except the spare. When the
tire pressure monitoring system warning light is
lit, one or more of your tires is significantly
under-inflated. You should stop and check your
tires as soon as possible, and inflate them to theproper pressure as indicated on the vehicle’s tire
information placard. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire malfunction. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stop-
ping ability. Each tire, including the spare, should
be checked monthly when cold and set to the
recommended inflation pressure as specified in
the vehicle placard and Owner’s Manual.
The recommended inflation pressure may also
be found on the Tire and Loading Information
label.
If the vehicle is being driven with low tire pres-
sure*, the light will illuminate and the chime will
sound for about 10 seconds.
*: lower than 26 psi (for 225/50R17 and
235/50R17 tires on
Roadster model)
lower than 28 psi (except for the above)
For additional information, see “Low tire pres-
sure warning system” in the “5. Starting and
driving” section and “Flat tire” in the “6. In case
of emergency” section. You can check the tire
pressure of all 4 tires on the trip computer
display. See “Trip computer” earlier in this sec-
tion.
WARNING

If the light does not come on with the
ignition switch turned ON, have the
vehicle checked by a NISSAN dealer
as soon as possible.

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

Tire pressure rises and falls depending on the
heat caused by the vehicle’s operation and the
outside temperature. Low outside temperature
can lower the temperature of the air inside the
tire which can cause a lower tire inflation pres-
sure. This may cause the low tire pressure
warning light to illuminate.
If the warning light illuminates in low ambient
temperatures as described above, check the tire
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.
Frequently check the tire pressure indicator on
the trip computer and adjust pressure of each
tire properly. See “Trip computer” in the “2.
Instruments and controls” section for the tire
pressure indicator.Low tire pressure warningIf the vehicle is being driven with low tire pres-
sure*, the low tire pressure warning light comes
on, and the chime sounds for about 10 seconds.
On the trip computer, the PSI indicator starts
flashing and the current display switches to the
tire pressure indicator.
*: lower than 26 psi (for 225/50R17 and
235/50R17 tires on
Roadster model)lower than 28 psi (except for the above)
For additional information regarding the above
warning, see “Trip computer” and
“Warning/indicator lights and audible remind-
ers” in the “2. Instruments and controls” section.
WARNING

If the low tire pressure warning light
in the meter panel comes on and/or
the PSI indicator on the trip computer
flashes while driving, avoid sudden
steering maneuvers or abrupt brak-
ing, reduce vehicle speed, pull off the
road to a safe location and stop the
vehicle as soon as possible. Serious
vehicle damage could occur and may
lead to an accident and could result
in serious personal injury. Check the
tire pressure for all four tires. Adjust
the tire pressure to the recom-
mended 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. (See “Flat tire” inthe “6. In case of emergency” section
for changing a flat tire.)

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 a NISSAN dealer as
soon as possible for tire replacement
and/or system resetting.

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.
CAUTION
Do not place metalized film or any metal
parts (antenna, etc.) on the windows.
This may cause poor reception of the
signals from the tire pressure sensors,
and the low tire pressure warning sys-
tem will not function properly.

TIRE PRESSURE
Low tire pressure warning systemThis vehicle is equipped with the low tire pres-
sure warning system. It monitors tire pressure of
all tires except the spare. When the low tire
pressure warning light is lit, one or more of your
tires is significantly under-inflated. The system
also 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.
The low tire pressure warning system will acti-
vate only when the vehicle is driven at speeds
above 20 MPH (32 km/h). Also, this system may
not detect a sudden drop in tire pressure (for
example a flat tire while driving).
For more details, refer to “Trip computer” and
“Low tire pressure warning light” in the “2.
Instruments and controls” section, “Low tire
pressure warning system” in the “5. Starting and
driving” section, and “Flat tire” in the “6. In case
of emergency” section.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 ColdTire 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 weight capacity is indi-
cated on the Tire and Loading Infor-
mation label. Do not load your ve-
hicle beyond this capacity.
Overloading your vehicle may resultin reduced tire life, unsafe operating
conditions due to premature tire fail-
ure, or unfavorable handling charac-
teristics and could also lead to a
serious accident. Loading beyond the
specified capacity may also result in
failure 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. Driving
faster than 85 MPH (137 km/h) may
result in tire failure, loss of control
and possible injury.

tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.

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)
1. P: The “P” indicates the tire is designed for
passenger vehicles. (Not all tires have this
information.)
2. Three-digit number (215): This number gives
the width in millimeters of the tire from side-
wall edge to sidewall edge.
3. Two-digit number (60): This number, known
as the aspect ratio, gives the tire’s ratio of
height to width.
4. R: The “R” stands for radial.
5. Two-digit number (16): This number is the
wheel or rim diameter in inches.

6. Two- or three-digit number (94): This number
is the tire’s load index. It is a measurement of
how much weight each tire can support. (You
may not find this information on all tires
because it is not required by law.)
7. 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.)

the front wheels on the vehicle could lead to
transmission damage.
For additional information regarding tires, refer to
“Important Tire Safety Information” (US) or “Tire
Safety Information” (Canada) in the Warranty
Information booklet.Care of wheels
Wash the wheels when washing the vehicle
to maintain their appearance.

Clean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.

Do not use abrasive cleaners when washing
the wheels.

Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.

NISSAN recommends that the road wheels
be waxed to protect against road salt in areas
where it is used during winter.Spare tire (T-type spare tire)Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident.
CAUTION

The T-type spare tire should be used
for emergency use only. It should be
replaced by the standard tire at the
first opportunity.

Drive carefully while the T-type spare
tire is installed.
Avoid sharp turns and abrupt braking
while driving.

Periodically check the T-type spare
tire inflation pressure, and always
keep it at 60 psi (420 kPa, 4.2 bar).

Do not drive your vehicle at speeds
faster than 50 MPH (80 km/h).

Do not use tire chains on a T-type
spare tire. Tire chains will not fit
properly on the T-type spare tire and
may cause damage to the vehicle.

Tire tread of the T-type spare tire will
wear at a faster rate than the stan-
dard tire. Replace the T-type spare
tire as soon as the tread wearindicators appear.

Because the T-type spare tire is
smaller than the original tire, ground
clearance is reduced. To avoid dam-
age to the vehicle, do not drive over
obstacles. Also, do not drive the ve-
hicle through an automatic car wash
since it may get caught.

Do not use the T-type spare tire on
other vehicles.

Do not use more than one T-type
spare tire at the same time.

Do not tow a trailer while the T-type
spare tire is installed.
