2002 NISSAN SENTRA check engine

WARNING
c
Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop the engine and do not
smoke or allow open flames or sparks
near the vehicle when refueling.
cFuel may be under pressure. Turn the
cap one-half turn and wait for any ``hiss-
ing'' sound to stop to prevent fuel from
spraying out and possibly causing per-
sonal injury. Then remove the cap.
cDo not attempt to top off the fuel
tank after the fuel pump nozzle shuts
off automatically. Continued refuel-
ing may cause fuel overflow, result-
ing in fuel spray and possibly fire.
cUse only an original equipment type
fuel filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious
malfunction and possible injury. It
could also cause the malfunction
indicator lamp to come on.Do not fill a portable fuel container in
the vehicle or trailer. Static electric-
ity can cause an explosion of flam-
mable liquid, vapor or gas in any
vehicle or trailer. To reduce the risk
of serious injury or death when fill-
ing portable fuel containers:
Ð Always place the container on
the ground when filling.
Ð Do not use electronic devices
while filling.
Ð Keep the pump nozzle in contact
with the container while you are
filling it.
Ð Use only approved portable fuel
containers for flammable liquid.
cNever pour fuel into the throttle body
to attempt to start your vehicle.
CAUTION
cIf fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage.cTighten until the fuel filler cap clicks.
Failure to tighten the fuel filler cap
properly may cause the
mal-
function indicator lamp (MIL) to illu-
minate. If the
lamp illuminates
because the fuel filler cap is loose or
missing, tighten or install the cap
and continue to drive the vehicle.
The
lamp should turn off after a
few driving trips. If thelamp
does not turn off after a few driving
trips, have the vehicle inspected by
an authorized NISSAN dealer.
cFor additional information, see the
``Malfunction indicator lamp (MIL)''
in the ``Instruments and controls''
section earlier in this manual.

START: (4)
This position activates the starter motor,
which starts the engine.
NISSAN VEHICLE IMMOBILIZER
SYSTEM (NVIS) (if so equipped)
The Nissan Vehicle Immobilizer System
(NVIS) will not allow the engine to start
without the use of a registered NVIS key.
If the engine fails to start using a 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 start,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.
c
Check the operation of warning lights
when key is turned to the ON (3) position.
See ``Warning/indicator lights and audible
reminders'' in the ``Instrument and con-
trols'' section.

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 in 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
``Maintenance and do-it-yourself'' section of
this manual.
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 of this manual.
DRAINING OF COOLANT
If the vehicle is to be left outside without
anti-freeze, drain the cooling system byopening 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 of this manual.
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 operate
your vehicle on snowy or icy roads, NIS-
SAN 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, most
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 they
are of 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
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 TEMPO-
RARY USE ONLY spare tires. Do not
use tire chains on dry roads.

hot and fan control to high speed.
3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. Wait until
no steam or coolant can be seen before
proceeding.
4. Open the hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or
looseness. Also check if the cooling fan
is running. The radiator hoses and radia-
tor should not leak water. If coolant is
leaking, the water pump belt is missing or
loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or
the engine cooling fan. The engine
cooling fan can start at any time when
the coolant temperature is high.
6. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the res-
ervoir tank if necessary. Have your ve-
hicle repaired at an authorized NISSAN
dealer.When towing your vehicle, all State (Provin-
cial in Canada) and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle.
Towing instructions are available from an
authorized NISSAN dealer. Local service
operators are generally familiar with the
applicable laws and procedures for towing.
To assure proper towing and to prevent
accidental damage to your vehicle, NISSAN
recommends having a service operator tow
your vehicle. It is advisable to have the
service operator carefully read the following
precautions:
WARNING
cNever ride in a vehicle that is being
towed.
cNever get under your vehicle after it
has been lifted by a tow truck.
CAUTION
cWhen towing, make sure that the
transmission, axles, steering system
and powertrain are in working con-
dition. If any unit is damaged, dollies
must be used.

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 ``NISSAN Ser-
vice and Maintenance Guide.'' You must
refer to that guide to ensure that necessary
maintenance is performed on your Nissan
at regular 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 and 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.
