2002 NISSAN ALTIMA maintenance

START (4)
This position activates the starter motor,
which starts the engine.
NISSAN VEHICLE IMMOBILIZER
SYSTEM (NVIS)
The Nissan Vehicle Immobilizer System
(NVIS) will not allow the engine to run
without the use of the registered NVIS key.
If the engine fails to run using the registered
NVIS key, it may be due to interference
caused by another NVIS key, an automated
toll road device or automated payment de-
vice on the key ring. Restart the engine
using the following procedures:
1. Leave the ignition switch in the ON posi-
tion for approximately 5 seconds.
2. Turn the ignition switch to the OFF or
LOCK position and wait approximately 5
seconds.
3. Repeat step 1 and 2 again.
4. Restart the engine while holding the de-
vice (which may have caused the inter-
ference) separate from the registered
NVIS key.If this procedure allows the engine to run,
NISSAN recommends placing the regis-
tered NVIS key on a separate key ring to
avoid interference from other devices.cMake sure the area around the vehicle is
clear.
cMaintenance items listed here should be
checked periodically, for example, each
time you check engine oil.
cCheck that all windows and lights are
clean.
cVisually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
cLock all doors.
cPosition seat and adjust head restraints.
cAdjust inside and outside mirrors.
cFasten seat belts and ask all passengers
to do likewise.
cCheck the operation of warning lights
when key is turned to the ON (3) position.

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-test or
while driving, take the vehicle to an autho-
rized NISSAN dealer for repair.
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 brake 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.cTire type and condition of tires may
also affect braking effectiveness.
When replacing tires, install the
specified size of tire on all four
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 ``Technical and
consumer information'' section of
this manual.
Refer to ``Wheels and tires'' in the
``Maintenance and do-it-yourself'' sec-
tion of this manual.When driving on slippery surfaces or sud-
denly avoiding obstacles on roads, the ve-
hicle might swerve or slip. With the vehicle
traction control system, sensors detect
these movements and control the braking
and engine output to help improve vehicle
stability while driving.
cWhen the traction control system is op-
erating, the slip indicator in the instru-
ment panel blinks.
cIf the slip indicator blinks, the vehicle is
under slippery conditions. Be sure to
drive carefully. See ªSlip indicator lightº,
and ªtraction control off indicator lightº in
the ªInstruments and controlsº section.
cIf a malfunction occurs in the system,
the
andindicator lights come
on in the meter panel.
As long as these warning lights are on,
the traction control function is canceled.
The vehicle will behave like a vehicle
without the system.
TRACTION CONTROL
SYSTEM (TCS)
5-20Starting and driving
ZX

WARNING
cThe traction control system is de-
signed to help improve driving sta-
bility but does not prevent accidents
due to abrupt steering operation at
high speeds or by careless or dan-
gerous driving techniques. Reduce
vehicle speed and be especially
careful when driving and cornering
on slippery surfaces and always
drive carefully.
cIf suspension parts such as shock
absorbers, struts, springs and bush-
ings are not standard equipment or
are extremely deteriorated, the trac-
tion control off indicator light may
come on.
cWhen driving on extremely inclined
surfaces such as higher banked cor-
ners, the traction control system
may not operate properly or the
indicator light may come on.
Do not drive on these types of roads.cIf tires other than the recommended
ones are used, the traction control
system may not operate properly or
the
indicator light may come on.
cThe traction control system is not a
substitute for winter tires or tire
chains on a snow covered road.
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'' 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 ``Maintenance
and do-it-yourself '' 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
before operating the vehicle. See ``Chang-
ing engine coolant'' in the ``Maintenance
and do-it-yourself'' section.
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 an authorized
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
U.S. States and Canadian Provinces pro-
hibit 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. Make sure theyare the proper size for the tires on your
vehicle and are installed according to the
chain manufacturer's suggestions.
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 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 much 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-
shifting too fast, the drive wheels
will lose even more traction.

cThe spare tire is designed for emer-
gency use. See specific instructions
under the heading ``Wheels and
tires'' in the ``Maintenance and do-it-
yourself'' section of this manual.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, clothing
or painted surfaces. Battery fluid is a
corrosive sulfuric 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 the 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.

Floor mat positioning aid
(Driver's side only)
This vehicle includes a front floor mat
bracket to act as a floor mat positioning aid.
NISSAN floor mats have been specially
designed for your vehicle model. The driv-
er's side floor mat has a grommet hole
incorporated in it. Position the mat by plac-
ing the floor mat bracket hook through the
floor mat grommet hole while centering the
mat in the footwell.
Periodically check to make certain the mats
are properly positioned.
SEAT BELTS
The seat belts can be cleaned by wiping
them with a sponge dampened in a mild
soap solution. Allow the belts to dry com-
pletely in the shade before using them. See
ªSeat belt maintenanceº in the ªSeats, re-
straints and supplemental air bag systemsº
section of this owner's manual.
WARNING
Do not allow wet seat belts to roll up in
the retractor. NEVER use bleach, dye,
or chemical solvents to clean the seat
belts, since these may severely weaken
the seat belt webbing.
MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
1. The accumulation of moisture-retaining
dirt and debris in body panel sections,
cavities, and other areas.
2. Damage to paint and other protective
coatings caused by gravel and stone
chips or minor traffic accidents.
ENVIRONMENTAL FACTORS IN-
FLUENCE THE RATE OF COR-
ROSION
Moisture
Accumulation of sand, dirt and water on the
vehicle body underside can accelerate cor-
rosion. Wet floor coverings will not dry com-
pletely inside the vehicle, and should be
removed for drying to avoid floor panel
corrosion.
Relative humidity
Corrosion will be accelerated:
cin areas of high relative humidity.
cin areas where the temperatures stay
above freezing.

Your new NISSAN has been designed to
have minimum maintenance requirements
with longer service intervals to save you
both time and money. However, some day-
to-day and regular maintenance is essential
to maintain your NISSAN's good mechani-
cal condition, as well as its emission and
engine performance.
It is the owner's responsibility to make sure
that the scheduled maintenance, as well as
general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
proper maintenance. You are a vital link in
the maintenance chain.
Scheduled maintenance
For your convenience, both required and
optional scheduled maintenance items are
described and listed in your ªNissan Service
and Maintenance Guide.º You must refer to
that guide to ensure that necessary mainte-
nance is performed on your Nissan at regu-
lar intervals.
General maintenance
General maintenance includes those items
which should be checked during normalday-to-day operation of the vehicle. They
are essential if your vehicle is to continue to
operate properly. It is your responsibility to
perform these maintenance procedures
regularly as prescribed.
Performing general maintenance checks re-
quire minimal mechanical skill and only a
few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, an authorized NISSAN dealer.
Where to go for service
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and tuned by an autho-
rized NISSAN dealer.
NISSAN technicians are well-trained spe-
cialists who are kept up-to-date with the
latest service information through technical
bulletins, service tips, and in-dealership
training programs. They are completely
qualified to work on NISSAN vehicles
beforethey work on your vehicle, rather
than after they have worked on it.
You can be confident that an authorized
NISSAN dealer's service department per-forms the best job to meet the maintenance
requirements on your vehicle Ð in a reliable
and economic way.
