1997 NISSAN SENTRA spare wheel

and releases hydraulic pressure (like pump-
ing the brakes very quickly). While the ac-
tuator is working, you may feel a pulsation in
the brake pedal and hear a noise or vibra-
tion from the actuator under the hood. This
is normal and indicates that the anti-lock
system is working properly. However, the
pulsation may indicate that road conditions
are hazardous and extra care is required
while driving.
Self-test feature
The anti-lock brake system is sophisticated,
with electronic sensors, electric pumps, and
hydraulic solenoids controlled by a com-
puter. The computer has a built-in diagnos-
tic 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 is not an indica-
tion of any malfunction. If the computer
senses any malfunction, it switches the anti-
lock brake system OFF and turns on the
ABS brake warning light in the dashboard.
The brake system then operates normally,
but without anti-lock assistance.
If the light comes on during the self check orwhile driving, take your vehicle to your NIS-
SAN dealer for repair at your earliest con-
venience.
WARNING
cThe anti-lock brake system is a so-
phisticated device, but it cannot pre-
vent accidents resulting from care-
less or dangerous driving tech-
niques. It can help maintain vehicle
control during braking on slippery
surfaces, but remember that the
stopping distance on slippery sur-
faces 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 distance from the vehicle in
front of you. Ultimately, the respon-
sibility for safety of self and others
rests in the hands of the driver.
cTire type and condition may also
affect braking effectiveness.
cWhen replacing tires, install the
specified size of tires on all 4 wheels.c
When 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
``Tire placard'' in the Owner's Manual
index.
cRefer 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 to it through the key hole.
If the lock becomes frozen, heat the key
before 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. Refillbefore operating the vehicle. See ``Chang-
ing Engine Coolant'' in the ``Do-it-yourself
operations'' section.
Tire equipment
1. SUMMER tires are of a tread design 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 NIS-
SAN 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 of 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
according 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 suggestions.Use only
SAE Class ªSº chains.Other types may
damage your vehicle. Use chain tension-
ers when recommended by the tire chain
manufacturer to ensure a tight fit. Loose
end links of the tire chain must be se-
cured or removed to prevent the possi-
bility of whipping action damage to the
fenders or underbody. If possible, avoid
fully loading your vehicle when using tire
chains. In addition, drive at a reduced
speed. Otherwise, your vehicle may be
damaged and/or vehicle handling and
performance may be adversely affected.
Never install tire chains on T-type spare
tires. Do not use tire chains on dry roads.

Getting the spare tire and tools
1. Open the trunk. Lift the trunk floor carpet-
ing and spare tire cover. Remove the tool
bag and the spare tire. Use the tapered
end of the jack rod (found in the tool bag)
to loosen the spare tire hold-down bolt.
2. Push the two release clips on the jack
access door, and pull the door open. To
remove the jack, turn the jack screw
counterclockwise. Use the tapered end
of the jack rod (found in the tool bag) to
loosen the jack from its storage position.
3. When the spare tire is installed on the
vehicle, place the damaged tire in the
storage area. Put the jack rod in the tool
bag and place the tool bag in the storage
area.
4. Place the spare tire cover and the trunk
floor carpeting over the damaged tire.
5. Install the jack in its storage area and
tighten the jack screw.
6. Close the jack access door. Close the
trunk.
Blocking wheels
Place suitable blocks at both the front and
back of the wheel diagonally opposite the
flat tire to prevent the vehicle from rolling
when it is jacked up.
WARNING
Be sure to block the wheel as the ve-
hicle may move and could cause per-
sonal injury.

cNever jack up the vehicle more than
necessary.
cNever use blocks on or under the
jack.
cDo not start or run engine while
vehicle is on the jack as it may cause
the vehicle to move.
cDo not allow passengers to stay in
the vehicle while it is on the jack.
cNever run the engine with a wheel off
the ground. It may cause the vehicle
to move. This is especially true for
models equipped with limited slip
differential carrier.
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 spare tire on and tighten
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 N²m)
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

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
accident or sudden stop.
cThe T-type spare tire and small size
spare tire are designed for emer-
gency use. See specific instructions
under the heading ``Wheels and
tires'' in the ``Do-it-yourself opera-
tions'' section.To start your engine with a booster battery,
the instructions and precautions below must

Maximum inflation pressure
Do not exceed the maximum inflation pres-
sures shown on the side wall of the tire.
Tire inflation pressure
Periodically check the tire pressure (including
spare). Incorrect tire pressure may adversely
affect tire life and vehicle handling. Tire pres-
sure should be checked when tires are
COLD. Tires are considered COLD after the
vehicle has been parked for three or morehours, or driven less than 1 mile (1.6 km).
COLD tire pressures are shown on the tire
placard affixed to the driver side center pillar.
WARNING
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 have loaded your vehicle
heavily, use a tire pressure gauge to
ensure that the tire pressure is at the
specified level.
cDo not drive your vehicle over 85
MPH (140 km/h) unless it is equipped
with high speed capability tires.
Driving faster than 85 MPH (140
km/h) may result in tire failure, loss
of control and possible injury.
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 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 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 ªSº 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 a T-type spare
tire. Do not use tire chains on dry roads.
Tire rotation
NISSAN recommends rotating the tires
every 7,500 miles (12,000 km).
See ``Flat tire'' in the ``In case of emergency''
section for tire replacing procedures.
As soon as possible, tighten the wheel
nuts to the specified torque with a nut
tightening torque:
72 to 87 ft-lb (98 to 118 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 tire rotation inter-
val.
ADI0656

WARNING
cAfter rotating the tires, adjust the tire
pressure.
cRetighten the wheel nuts after the
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
in the tire rotation.
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 should be replaced.
cThe original tires have a built-in
tread wear indicator. When the wear
indicator is visible, the tire should be
replaced.
c
Improper service for a T-type spare tiremay result in serious personal injury. If
it is necessary to repair the T-type
spare tire, contact your NISSAN 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 information''
section.
WARNING
cThe use of tires other than those
recommended, or the mixed use of
tires of different brands, construc-
tion (bias, bias-belted or radial), or
tread patterns can adversely affect
the ride, braking, handling, ground
clearance, body-to-tire clearance,
snow chain clearance, speedometer
calibration, headlight aim and
bumper height. Some of these ef-
fects may lead to accidents and
could result in serious personal
injury.MDI0004
