2012 NISSAN 370Z COUPE inflation pressure

THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
.The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system com-
ponents.
. Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They
may ignite and cause a fire.
CAUTION
.Do not use leaded gasoline. Depos-
its from leaded gasoline seriously
reduce the three-way catalyst’s abil-
ity to help reduce exhaust pollu-
tants.
. Keep your engine tuned up. Mal-
functions in the ignition, fuel injec- tion, or electrical systems can cause
overrich fuel flow into the three-way
catalyst, causing it to overheat. Do
not keep driving if the engine mis-
fires, or if noticeable loss of perfor-
mance or other unusual operating
conditions are detected. Have the
vehicle inspected promptly by a
NISSAN dealer.
. Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, dama-
ging the three-way catalyst.
. Do not race the engine while warm-
ing it up.
. Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the proper
tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitoring
System (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires
is significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
Starting and driving5-3

pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction indi-
cator is illuminated, the system may not be able
to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale
after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.
Additional information
.The TPMS does not monitor the tire
pressure of the spare tire.
. The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h) . Also, this system may not detect
a sudden drop in tire pressure (for example a flat tire while driving) .
. The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After the tire is inflated to the
recommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h)
to activate the TPMS and turn off the low tire
pressure warning light. Use a tire pressure
gauge to check the tire pressure.
. 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 pressure. This may cause
the low tire pressure warning light to
illuminate. If the warning light illuminates in
low ambient temperature, check the tire
pressure for all four tires.
For additional information, see “Low tire pres-
sure warning light” (P.2-12) and “Tire Pressure
Monitoring System (TPMS)” (P.6-2) .WARNING
. If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull off the road to a safe location and
stop the vehicle as soon as possi-
ble. Driving with under-inflated tires
may permanently damage the tires
and increase the likelihood of tire
failure. Serious vehicle damage
could occur and may lead to an
accident and could result in serious
personal injury. Check the tire pres-
sure 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 the light still illuminates
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. (See
“Flat tire” (P.6-2) for changing a flat
tire.)
. When a spare tire is mounted or a
wheel is replaced, the TPMS will not
function and the low tire pressure
warning light will flash for approxi-
mately 1 minute. The light will
remain on after 1 minute. Contact
your NISSAN dealer as soon as
possible for tire replacement and/
or system resetting.

If you have a flat tire, see “Flat tire” (P.6-2) .
TIRE PRESSURE
Tire Pressure Monitoring System (TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS) . 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 TPMS will activate only when the vehicle is
driven at speeds above 16 MPH (25 km/h).
Also, this system may not detect a sudden drop
in tire pressure (for example a flat tire while
driving) .
For more details, see “Low tire pressure warning
light” (P.2-12) , “Tire Pressure Monitoring Sys-
tem (TPMS)” (P.5-3) and “Tire Pressure Mon-
itoring System (TPMS)” (P.6-2) .
Tire inflation pressure
Check the pressure of the tires (including
the spare) often and always prior to long
distance trips. The recommended tire
pressure specifications are shown on the
Tire and Loading Information label under
the “Cold Tire Pressure” heading. The Tire
and Loading Information label is affixed to
the driver side center pillar. Tire pressuresshould 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 curb while 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 un-
der inflation, may adversely affect tire
life and vehicle handling.
WARNING
. Improperly inflated tires can fail
suddenly and cause an accident.
. The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.
S.S./C.M.V.S.S. label. The vehi-
cle weight capacity is indicated
on the Tire and Loading Infor-
mation label. Do not load your
vehicle beyond this capacity. Overloading your vehicle may
result in reduced tire life, unsafe
operating conditions due to pre-
mature tire failure, or unfavor-
able handling characteristics
and could also lead to a serious
accident. Loading beyond the
specified capacity may also re-
sult in failure of other vehicle
components.
. Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure
gauge to ensure that the tire
pressures are at the specified
level.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.

Checking the tire pressure
1. Remove the valve stem cap from thetire.
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 specifica- tion 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. Re-
check the pressure and add or release
air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, including the spare.

TYPES OF TIRES
WARNING
. When changing or replacing tires,
be sure all four tires are of the same
type (Example: Summer, All Season
or Snow) and construction. A
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.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information” (US) or “Tire
