check engine NISSAN MAXIMA 2003 A33 / 5.G Owner's Manual

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 mechanical condition, as
well as its emission and engine performance.
It is the owner's responsibility to make sure
that scheduled maintenance, as well as gen-
eral maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives the
proper maintenance care. You are a vital link
in the maintenance chain.
Scheduled maintenance:
For your convenience, both required and op-
tional scheduled maintenance items are de-
scribed and listed in your ªService and Main-
tenance Guideº. You must refer to that guide to
ensure that necessary maintenance is per-
formed on your NISSAN at regular intervals.
General maintenance:
General maintenance includes those items
which should be checked during normal day-
to-day operation of the vehicle. They are es-
sential if your vehicle is to continue to operate
properly. It is your responsibility to perform
these 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,
your NISSAN dealer.
Where to go for service:
If maintenance service is required or your
vehicle appears to malfunction, have the sys-
tems checked and tuned by an authorized
NISSAN dealer.
NISSAN technicians are well-trained special-
ists and are kept up to date with the latest
service information through technical bulletins,
service tips, and in-dealership training pro-
grams. They are completely qualified to work
on NISSAN vehiclesbeforethey work on your
vehicle, rather than after they have worked on
it.
You can be confident that your NISSAN deal-
er's service department performs the best job
to meet the maintenance requirements of your
vehicle Ð in a reliable and economic way.During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section.
If you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have
your NISSAN dealer check it promptly. In
addition, you should notify your NISSAN
dealer if you think that repairs are required.
When performing any checks or maintenance
work, closely observe the ªMaintenance pre-
cautionsº later in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMSAdditional information on the following
items with ª*º is found later in this section.Outside the vehicleThe 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. If necessary, adjust the pres-
sure in all tires, including the spare, to the

loose nuts. Tighten if necessary.
Tire rotation*:Tires should be rotated every
7,500 miles (12,000 km).
Wheel alignment and balance:If the vehicle
pulls 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.
For additional information regarding tires, refer
to ªImportant Tire Safety Informationº in the
Warranty Information Booklet (US) or ªTire
Safety Informationº in the Warranty and Road-
side Assistance Information booklet (Canada).
Windshield:Clean the windshield on a regu-
lar basis. Check the windshield at least every
six months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*:Check for cracks
or wear if they do not wipe properly.
Doors and engine hood:Check that all doors
and the engine hood operate smoothly as well
as the trunk lid or back hatch. Also make sure
that all latches lock securely. Lubricate if nec-essary. Make sure that the secondary latch
keeps the hood from opening when the pri-
mary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Inside the vehicleThe maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.
Warning lights and chimes:Make sure that
all warning lights and chimes are operating
properly.
Windshield wiper and washer*:Check that
the wipers and washer operate properly and
that the wipers do not streak.
Windshield defroster:Check that the air
comes out of the defroster outlets properly and
in good quantity when operating the heater or
air conditioner.
Steering wheel:Check for changes in thesteering conditions, such as excessive free
play, hard steering or strange noises.
Seats:Check seat position controls such as
seat adjusters, seatback recliner, etc. to en-
sure they operate smoothly and that all latches
lock securely in every position. Check that the
head restraints move up and down smoothly
and that the locks (if equipped) hold securely
in all latched positions.
Seat belts:Check that all parts of the seat belt
system (for example, buckles, anchors, adjust-
ers and retractors) operate properly and
smoothly, and are installed securely. Check
the belt webbing for cuts, fraying, wear or
damage.
Accelerator pedal:Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep
the floor mats away from the pedal.
Clutch pedal*:Make sure the pedal operates
smoothly and check that it has the proper free
play.
Brakes:Check that the brakes do not pull the
vehicle to one side when applied.
Brake pedal and booster*:Check the pedal
for smooth operation and make sure it has the
proper distance under it when depressed fully.

keep floor mats away from the pedal.
Parking brake*:Check that the lever has the
proper travel and make sure that the vehicle is
held securely on a fairly steep hill when only
the parking brake is applied.
Automatic transaxle P (Park) position
mechanism:On a fairly steep hill check that
the vehicle is held securely with the selector
lever in the P (Park) position without applying
any brakes.Under the hood and the vehicleThe maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Windshield washer fluid*:Check that there
is adequate fluid in the tank.
Engine coolant level*:Check the coolant
level when the engine is cold.
Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure
the hoses have no cracks, deformation, dete-
rioration or loose connections.
Brake and clutch fluid levels*:Make sure
that the brake and clutch fluid levels are be-
tween the MAX and MIN lines on the reservoir.Battery*:Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
Engine drive belts*:Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*:Check the level on the
dipstick after parking the vehicle on a level
spot and turning off the engine.
Power steering fluid level* and lines:Check
the level in the reservoir tank with the engine
off. Check the lines for proper attachment,
leaks, cracks, etc.
Automatic transaxle fluid level*:Check the
level on the dipstick after putting the selector
lever in P (Park) position with the engine idling.
Exhaust system:Make sure there are no
loose supports, cracks or holes. If the sound of
the exhaust seems unusual or there is a smell
of exhaust fumes, immediately locate the
trouble and correct it. (See ªPrecautions when
starting and drivingº in the ª5. Starting and
drivingº section for exhaust gas (carbon mon-
oxide).)
Underbody:The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is veryimportant to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. For additional information, see
ªCleaning exteriorº in the ª7. Appearance and
careº section.
Fluid leaks:Check under the vehicle for fuel,
oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping
from the air conditioner after use is normal. If
you should notice any leaks or if gasoline
fumes are evident, check for the cause and
have it corrected immediately.8-4
