2008 NISSAN 350Z tire size

sure 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 stays on after adjusting
the tire pressure and driving over 16
MPH (25 km/h), have the system
checked by a NISSAN dealer. 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, 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.

Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
CAUTION

The TPMS is not a substitute for the
regular tire pressure check. Be sure
to check the tire pressure regularly.

If the vehicle is being driven at
speeds of less than 16 MPH (25
km/h), the TPMS may not operate
correctly.

Be sure to install the specified size of
tires to the front and rear.
Low washer fluid warning light
This light comes on when the washer fluid is at a
low level. Add washer fluid as necessary. See
“Window washer fluid” in the “8. Maintenance
and do-it-yourself” section.
Seat belt warning light
The seat belt warning light and chime remind you
to fasten seat belts. The light illuminates when-
ever the ignition key is turned to ON, and will
remain illuminated until the driver’s seat belt is
fastened.
The seat belt warning light may also illuminate ifthe front passenger’s seat belt is not fastened
when the front passenger’s seat is occupied. For
5 seconds after the ignition switch is in the ON
position, the system does not activate the warn-
ing light for the front passenger.
See “Seat belts” in the “1. Safety — Seats, seat
belts and supplemental restraint system” section
for precautions on seat belt usage.
Supplemental air bag warning
light
After turning the ignition key to the ON position,
the supplemental air bag warning light will illu-
minate. The supplemental air bag warning light
will turn off after about 7 seconds if the system is
operational.
If any of the following conditions occur, the front
air bag, side air bag (if so equipped) and curtain
air bag (if so equipped), and pretensioner sys-
tems need servicing and your vehicle must be
taken to a NISSAN dealer.

The supplemental air bag warning light re-
mains on after approximately 7 seconds.

The supplemental air bag warning light
flashes intermittently.

The supplemental air bag warning light does
not come on at all.

The exhaust system and body should
be inspected by a qualified mechanic
whenever:
•The vehicle is raised for service.
•You suspect that exhaust fumes
are entering into the passenger
compartment.
•You notice a change in the sound
of the exhaust system.
•You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.THREE-WAY CATALYSTThe three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the converter are burned at high tem-
peratures to help reduce pollutants.
WARNING

The exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-mals or flammable materials away
from the exhaust system compo-
nents.

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. Deposits
from leaded gasoline will seriously
reduce the three-way catalyst’s abil-
ity to help reduce exhaust pollutants.

Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly by a NISSAN
dealer.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing 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
SYSTEM (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 plac-
ard 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 infla-
tion 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 pres-
sure 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

front of you. Ultimately, the driver is
responsible for safety.

Tire type and condition may also af-
fect braking effectiveness.
— When replacing tires, install the
specified size of tires on all four
wheels.
— When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. See “Tire and
Loading Information label” in the “9.
Technical and consumer informa-
tion” section of this manual.
— For detailed information, see
“Wheels and tires” in the “8. Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the systemhelps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the systemDepress the brake pedal and hold it down.
Depress the brake pedal with firm steady pres-
sure, but do not pump the brakes. The ABS will
operate to prevent the wheels from locking up.
Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.Self-test featureThe ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and does not indicate
a malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates theABS warning light on the instrument panel. The
brake system then operates normally, but with-
out anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.
Normal operationThe ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h). The speed varies according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are haz-
ardous and extra care is required while driving.

FREEING A FROZEN DOOR LOCKTo prevent a door lock from freezing, apply
deicer or glycerin to it through the key hole. If the
lock becomes frozen, heat the key before insert-
ing it into the key hole.ANTI-FREEZEIn the winter when it is anticipated that the
temperature will drop below 32°F (0°C), check
anti-freeze to assure proper winter protection.
For additional information, see “Engine Cooling
System” in the “8. Maintenance and do-it-
yourself” section.BATTERYIf the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain
maximum efficiency, the battery should be
checked regularly. For additional information,
see “Battery” in the “8. Maintenance and do-it-
yourself” section.DRAINING OF COOLANT WATERIf the vehicle is to be left outside without anti-
freeze, drain the cooling system by opening the
drain plug located under the radiator. Refill
before operating the vehicle. See “Engine cool-
ing system” in the “8. Maintenance and do-it-
yourself” section for changing engine coolant.
TIRE EQUIPMENT1. SUMMER tires are of a tread design to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your vehicle
on snowy or icy roads, NISSAN recommends
the use of MUD & SNOW or ALL SEASON
tires on all four wheels. Consult a NISSAN
dealer for the tire type, size, speed rating and
availability information.
2. For additional traction on icy roads, studded
tires may be used. However, some provinces
and states prohibit their use. Check local,
state and provincial laws before installing
studded tires.
Skid and traction capabilities of stud-
ded snow tires, on wet or dry surfaces,
may be poorer than that of non-studded
snow tires.
3. Tire chains may be used. For details, see
“Tire chains” in the “8. Maintenance and
do-it-yourself” section of this manual.
SPECIAL WINTER EQUIPMENTIt is recommended that the following items be
carried in the vehicle during winter:

a scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.

a sturdy, flat board to be placed under the
jack to give it firm support.

a shovel to dig the vehicle out of snow-drifts.

extra window washer fluid to refill the reser-
voir tank.DRIVING ON SNOW OR ICE
WARNING

Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” un-
der these conditions. Try to avoid
driving on wet ice until the road is
salted or sanded.

Whatever the condition, drive with
caution. Accelerate and slow down

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, reposi-
tion the gauge to eliminate this leak-
age.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.

TIRE LABELINGFederal law requires tire manufacturers
to place standardized information on the
sidewall of all tires. This information iden-
tifies and describes the fundamental
characteristics of the tire and also pro-
vides the tire identification number (TIN)
for safety standard certification. The TIN
can be used to identify the tire in case of
a recall.
1
Tire size (example: P215/65R15
95H)
1. P: The “P” indicates the tire is de-
signed for passenger vehicles. (Not all
tires have this information.)
2. Three-digit number (215): This num-
ber gives the width in millimeters of the
tire from sidewall edge to sidewall
edge.
3. Two-digit number (65): This number,
known as the aspect ratio, gives thetire’s ratio of height to width.
4. R: The “R” stands for radial.
5. Two-digit number (15): This number is
the wheel or rim diameter in inches.
6. Two- or three-digit number (95): 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 be-
cause it is not required by law.
7. Tire Speed Rating. You should not
drive the vehicle faster than the tire
speed rating.
