tire pressure NISSAN SENTRA 2002 B15 / 5.G Owners Manual

cKeep your engine tuned up.
cFollow the recommended periodic main-
tenance schedule.
cKeep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and wastes fuel.
cKeep the front wheels in correct align-
ment. Improper alignment increases tire
wear and lowers fuel economy.
cAir conditioner operation lowers fuel
economy. Use the air conditioner only
when necessary.
cWhen cruising at highway speeds, it is
more economical to use the air condi-
tioner and leave the windows closed to
reduce drag.
WARNING
Do not park the vehicle over flammable
materials such as dry grass, waste pa-
per or rags. They may ignite and cause
a fire.
1. Firmly apply the parking brake.
2.Manual transmission models:
Place the selector lever in the R (Re-
verse) position. When parking on an up-
hill grade, place the selector lever in 1
(First) gear.Automatic transmission models:
Move the shift selector lever to the P
(Park) position.
WARNING
cSafe parking procedures require that
both the parking brake be set and
the transmission placed into P (Park)
for automatic transmission models
or in an appropriate gear for manual
transmission models. Failure to do
so could cause the vehicle to move
unexpectedly or roll away and result

Installing the spare tire
The TEMPORARY USE ONLY spare tire
is designed for emergency use. See spe-
cific instructions under the heading
``Wheels and tires'' in the ``Maintenance
and do-it- yourself'' section of this own-
er's manual.
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the spare tire on and tighten
the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheelnuts alternately and evenly 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 se-
curely in the sequence as illustrated.
Lower the vehicle completely.
WARNING
cIncorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
cDo not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.
cRetighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of 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 Nzm)The wheel nuts must be kept tightened to
specifications 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 placard affixed to the driver's door
center pillar.
5.
With the spare tire installed on the vehicle,
place the damaged tire in the spare tire
storage area. Put the jack rod and wheel
nut wrench in the tool bag and place the
tool bag in the spare tire storage area.

nance work, closely observe the ``Mainte-
nance precautions'' later in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with ``*'' is found later in this sec-
tion.
Outside the vehicle
The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Tires*Check the pressure with a gauge at
least once a month and always prior to long
distance trips, including the spare, and ad-
just to the specified pressure if necessary.Check carefully for damage, cuts or exces-
sive wear.
Wheel nuts*When checking the tires, make
sure no wheel nuts are missing, and check for
any loose wheel nuts. Tighten if necessary.
Tire rotation*Tires should be rotated every
7,500 miles (12,000 km).
Wheel alignment and balanceIf the ve-
hicle should pull 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.

checked when tires are COLD. Tires are
considered COLD after the vehicle has
been parked for three or more hours, or
driven less than 1 mile (1.6 km) at moderate
speeds. COLD tire pressures are shown on
the tire placard affixed to the driver's side
rear door pillar.
WARNING
cImproperly inflated tires can fail sud-
denly and cause an accident.
c
The vehicle weight capacity is indi-
cated on the tire placard. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may result
in 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.
cBefore 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.cDo not drive your vehicle over 85
MPH (140 km/h) unless it is equipped
with high speed rated tires. Driving
faster than 85 MPH (140 km/h) may
result in tire failure, loss of control
and possible injury.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance Information
booklet (Canada).
TYPES OF TIRES
WARNING
cWhen changing or replacing tires, be
sure all four tires are of the same
type (i.e., summer, all season or
snow) and construction. An autho-
rized NISSAN dealer may be able to
help you with information about tire
type, size, speed rating and availabil-
ity. Replacement tires may have a
lower speed rating than the factory
equipped tires, and may not matchthe potential maximum vehicle speed.
Never exceed the maximum speed rat-
ing of the tire.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Informa-
tion Booklet (US) or ``Tire Safety In-
formation'' in the Warranty and Road-
side Assistance Information booklet
(Canada).
All Season tires
NISSAN specifies All Season tires on some
models to provide good performance all
year round, including snowy and icy road
conditions. All Season tires are identified by
``ALL SEASON'' and/or ``M&S'' on the tire
sidewall. Snow tires have better snow trac-
tion than All Season tires and may be more
appropriate in some areas.
Summer tires
NISSAN specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is sub-
stantially reduced in snow and ice. Summer
tires do not have the tire traction rating
``M&S'' on the tire sidewall.

The wheel nuts must be kept tightened to
specifications at all times. It is recom-
mended that wheel nuts be tightened to
specification at each tire rotation interval.
WARNING
cAfter rotating the tires, check and
adjust the tire pressure.
cRetighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
cDo not include the spare tire in the
tire rotation.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance Information
booklet (Canada).
Tire wear and damage
WARNING
c
Tires should be periodically inspected
for wear, cracking, bulging, or objects
caught in the tread. If excessive wear,
cracks, bulging, or deep cuts are
found, the tire(s) should be replaced.
cThe original tires have a built-in
tread wear indicator. When the wear
indicator is visible, the tire(s) should
be replaced.cImproper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact an authorized
NISSAN dealer.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance Information
booklet (Canada).
Replacing tires and wheels
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. Recom-
mended types and sizes are shown in
``Wheel/Tire Size'' of the ``Technical and con-
sumer information'' section of this manual.
WARNING
c
The use of tires other than those
recommended, or the mixed use of
tires of different brands, construc-
tion(bias, bias-belted, 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.
cIf the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different offset
could cause premature tire wear, de-
grade vehicle handling characteris-
tics and/or interference with the
brake discs/drums. Such interfer-
ence can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. Refer to ªWheel/tire
sizeº in the ªTechnical and con-
sumer informationº section of this
manual for wheel off-set dimen-
sions.
cDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have unknown
structural damage and could fail
without warning.cThe use of retread tires is not recom-
mended.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance Information
booklet (Canada).
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle. Spin
balancing the front wheels on the vehicle
could lead to transmission damage.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Informa-
tion Booklet (US) or ``Tire Safety In-
formation'' in the Warranty and Road-
side Assistance Information booklet
(Canada).
Care of wheels
cWash the wheels when washing the
vehicle to maintain their appearance.
cClean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
cDo not use abrasive cleaners when
washing the wheels.
c
Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
cNISSAN recommends waxing the road
wheels to protect against road salt in
areas where it is used during winter.
Spare tire (TEMPORARY USE
ONLY)
Observe the following precautions if the TEM-
PORARY USE ONLY spare tire must be used,
otherwise your vehicle could be damaged or
involved in an accident:
Maintenance and do-it-yourself8-47
ZX

WARNING
cThe spare tire should be used for
emergency use only. It should be
replaced with the standard tire at the
first opportunity to avoid possible
tire or differential damage.
cDrive carefully while the TEMPO-
RARY USE ONLY spare tire is in-
stalled. Avoid sharp turns and
abrupt braking while driving.
cPeriodically check spare tire infla-
tion pressure. Always keep the pres-
sure of the TEMPORARY USE ONLY
spare tire at 60 psi (420 kPa, 4.2 bar).
cWith the TEMPORARY USE ONLY
spare tire installed do not drive the
vehicle at speeds faster than 50 MPH
(80 km/h).
cWhen driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on
the rear wheels and the original tire
used on the front wheels (drive
wheels). Use tire chains only on the
front (original) tires.cTire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster
rate than the standard tire. Replace
the spare tire as soon as the tread
wear indicators appear.
cDo not use the spare tire on other
vehicles.
cDo not use more than one spare tire
at the same time.
cDo not tow a trailer when the TEM-
PORARY USE ONLY spare tire is
installed.CAUTION
c
Do not use tire chains on the TEMPO-
RARY USE ONLY spare tire. Tire
chains will not fit properly and may
cause damage to the vehicle.
cBecause the TEMPORARY USE
ONLY spare tire is smaller than the
original tire, ground clearance is re-
duced. To avoid damage to the ve-
hicle, do not drive over obstacles.
Also, do not drive the vehicle
through an automatic car wash since
it might get caught.
