1997 NISSAN ALTIMA tire type

SEAT BELT EXTENDERS
If, because of body size or driving position,
it is not possible to properly fit the lap-
shoulder belt and fasten it, an extender is
available which is compatible with the in-
stalled seat belts. The extender adds ap-
proximately 8 inches (200 mm) of length
and may be used for either the driver or front
passenger seating position. See your NIS-
SAN dealer for assistance if the extender is
required.
WARNING
cOnly NISSAN belt extenders, made
by the same company which made
the original equipment belts, should
be used with NISSAN belts.
cPersons who can use the standard
seat belt should not use an extender.
Such unnecessary use could result
in serious personal injury in the
event of an accident.
SEAT BELT MAINTENANCE
cTo clean the seat belt webbings,apply
a mild soap solution or any solution rec-
ommended for cleaning upholstery or
carpets. Then brush the webbing, wipe it
with a cloth and allow it to dry in the
shade. Do not allow the seat belts to
retract until they are completely dry.
cIf dirt builds up on the shoulder belt
guideof the seat belt anchors, the seat
belts may retract slowly. Wipe the shoul-
der belt guide with a clean, dry cloth.
cPeriodically check to see that the seat
belt and the metal components,such
as buckles, tongues, retractors, flexible
wires and anchors, work properly. If
loose parts, deterioration, cuts or other
damage on the webbing is found, the
entire seat belt assembly should be re-
placed.
WARNING
cInfants and small children should
always be placed in an appropriate
child restraint while riding in the ve-
hicle. Failure to use a child restraint
can result in serious injury or death.
cChildren and infants should never be
carried on your lap. It is not possible
for even the strongest adult to resist
the forces of a severe accident. The
child could be crushed between the
adult and parts of the vehicle. Also,
do not put the same seat belt around
both your child and yourself.
cNissan recommends that the child
restraint be installed in the rear seat.
According to accident statistics,
children are safer when properly re-
strained in the rear seat than in the
front seat.
cAn improperly installed child re-
straint could lead to serious injury or
death in an accident.
In general, child restraints are designed to
be installed with a lap belt or the lap portion
of a three point type seat belt.

If the light comes on during the self-test or
while you are driving, you should take your
car to your NISSAN dealer for repair at your
earliest convenience.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent
accidents resulting from careless or
dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces, but re-
member that the stopping distance on
slippery surfaces will be longer than on
normal surfaces, even with the anti-
lock system. Stopping distances may
also be longer on rough, gravel or
snow covered roads, or if you are using
tire chains. Always maintain a safe dis-
tance from the vehicle in front of you.
Ultimately, the responsibility for safety
of self and others rests in the hands of
the driver.
Tire type and condition of tires may
also affect braking effectiveness.
cWhen replacing tires, install the
specified size of tire on all 4 wheels.cWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. For tire
placard location information, refer to
ªTire placardº in the Owner's Manual
index.
Refer to ``Wheels and Tires'' in the
``Do-it-yourself operations'' section of
this manual.
Freeing a frozen door lock
To prevent a door lock from freezing, apply
de-icer or glycerin through the key hole. If
the lock becomes frozen, heat the key be-
fore inserting it into the key hole.
Anti-freeze
In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC),
check the anti-freeze (ethylene glycol base)
to assure proper winter protection. For de-
tails, see ``Engine cooling system'' in the
``Do-it-yourself operations'' section.
Battery
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For
details, see ``Battery'' in the ``Do-it-yourself
operations'' section.
Draining of coolant water
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by
opening the drain valves located under the
radiator and on the engine block. Refill

Tire equipment
1. SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON tires on all four
wheels. Please consult your NISSAN
dealer for the tire type, size, speed rating
and availability information.
2. For additional traction on icy roads, stud-
ded 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 studded
snow tires, on wet or dry surfaces, may
be poorer than that of non-studded snow
tires.3. Tire chains may be used if desired. Make
sure they are the proper size for the tires
on your vehicle and are installed accord-
ing to the chain manufacturer's sugges-
tions.
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size
for the tires on your vehicle and are installed
according to the chain manufacturer's sug-
gestions.Use only SAE Class ``S'' chains.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chain must be
secured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or underbody. If possible, avoid fully loading
your vehicle when using tire chains. In ad-
dition, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or ve-
hicle handling and performance may be
adversely affected.
Never install tire chains on T-type spare
tires. Do not use tire chains on dry roads.
Special winter equipment
It is recommended that the following items
be carried in the vehicle during winter:
1. A scraper and stiff-bristled brush to re-
move ice and snow from the windows
and wiper blades.
2. A sturdy, flat board to be placed under
the jack to give it firm support.
3. A shovel to dig the vehicle out of snow-
drifts.
4. Extra window washer fluid to refill the
reservoir tank.
Driving on snow or ice
WARNING
cWet ice (32ÉF, 0ÉC and freezing rain),
very cold snow or ice can be slick
and very hard to drive on. The ve-
hicle will have a lot less traction or
``grip'' under these conditions. Try to
avoid driving on wet ice until the
road is salted or sanded.
cWhatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-

Installing wheel
The T-type spare tire is designed for
emergency use. See specific instruc-
tions under the heading ``Wheels and
tires'' in the ``Do-it- yourself operations''
section.
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the wheel on and install the
wheel nuts finger-tight.
3. With the wheel nut wrench, tighten wheel
nuts 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.
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.As soon as possible tighten the wheel
nuts to the specified torque with a torque
wrench.
Wheel nut tightening torque:
72 to 87 ft-lb
(98 to 118 Nzm)
Adjust tire pressure to the COLD pres-
sure.
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 center console lid.
cRetighten the wheel nuts when the
vehicle has been run for 600 miles
(1,000 km).
5. Securely store the spare tire and jacking
equipment in the vehicle.
WARNING
cAlways make sure that the spare tire
and jacking equipment are properly
secured after use. Such items can
become dangerous projectiles in an

cThe T-type spare tire is designed for
emergency use. See specific instruc-
tions under the heading ``Wheels
and tires'' in the ``Do-it-yourself op-
erations'' section.To start your engine with a booster battery,
the instructions and precautions below must
be followed.
WARNING
cIf done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could
also damage your vehicle.
cExplosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away
from the battery.
cDo not allow battery fluid to come
into contact with eyes, skin, cloth or
painted surfaces. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.
cKeep battery out of the reach of
children.
cThe booster battery must be rated at
12 volts. Use of an improper rated
battery can damage your vehicle.cWhenever working on or near a bat-
tery, always wear suitable eye pro-
tectors (for example, goggles or in-
dustrial safety spectacles) and
remove rings, metal bands, or any
other jewelry. Do not lean over the
battery when jump starting.
cDo not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
cYour vehicle has an automatic en-
gine cooling fan. It could come on at
any time. Keep hands and other ob-
jects away from it.

Types of tires
CAUTION
When changing or replacing tires, be
sure all four tires are of the same type
(i.e., Summer, All Season 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.
All Season tires
NISSAN specifies All Season tires on some
models to provide good performance for
use all year around, including snowy and icy
road conditions. All Season Tires are iden-
tified 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 tires
NISSAN specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance in
snow and ice is substantially reduced. Sum-
mer tires do not have the tire traction rating
``M&S'' on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of ``SNOW'' or ``ALL SEASON'' tires on
all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.
Generally, snow tires have lower speed
ratings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
For additional traction on icy roads, studded
tires may be used. However, some prov-
inces and states prohibit their use. Check
local, state and provincial laws before in-stalling studded tires. Skid and traction ca-
pabilities of studded snow tires on wet or dry
surfaces may be poorer than that of non-
studded snow tires.
Tire chains
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size
for the tires on your vehicle and are installed
according to the chain manufacturer's sug-
gestions.Use only SAE class ``S'' chains.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chain must be
secured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or underbody. If possible, avoid fully loading
your vehicle when using tire chains. In ad-
dition, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or ve-
hicle handling and performance may be
adversely affected.
Never install tire chains on T-type spare
tires. Do not use tire chains on dry roads.

Tire rotation
NISSAN recommends that tires be rotated
every 7,500 miles (12,000 km).
Tighten wheel nuts to 72 to 87 ft-lb
(98 to 118 Nzm).
See ``Flat tire'' in the ``In case of emergency''
section for tire replacing procedures.
WARNING
cAfter rotating the tires, adjust the tire
pressure.cRetighten the wheel nuts after the
aluminum wheels have been run for
the first 600 miles (1,000 km) (also in
cases of a flat tire, etc.).
cDo not include the T-type spare tire
or any other small size spare tire in
the tire rotation.
Tire wear and damage
WARNING
cTires should be periodically in-
spected for wear, cracking, bulging,
or objects caught in the tread. If
excessive wear, cracks, bulging, or
deep cuts are found, the tire should
be replaced.
cThe original tires have a built-in
tread wear indicator. When the wear
indicator is visible, the tire should be
replaced.

cImproper service for a T-type spare
tire may result in serious personal
injury. If it is necessary to repair the
T-type spare tire, contact your NIS-
SAN dealer.Changing tires and wheels
When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. Recommended types
and sizes are shown in ``Wheels and tires''
in the ``Technical and consumer informa-
tion'' section.
WARNING
c
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.
cIf 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, possiblydegraded vehicle handling charac-
teristics and/or interference with the
brake discs/ drums. Such interfer-
ence can lead to decreased braking
efficiency and/or early brake
pad/shoe wear.
c
Do not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-
ing.
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.
Care of wheels
cWash the wheels when washing the ve-
hicle to maintain their appearance.
cClean the inner side of the wheels when
