1997 NISSAN MAXIMA ECU

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 do 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 precautions in the
ªDo-it-yourself operationsº section.
Additional information on the following
items with ª*º is found in the ªDo-it-
yourself operationsº section.
OUTSIDE THE VEHICLE
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Tires*Check the pressure with a gauge peri-
odically when at a service station, including the
spare, and adjust to the specified pressure if
necessary. Check carefully for damage, cuts
or excessive wear.
Wheel nuts*When checking the tires, make
sure no nuts are missing, and check for any
loose nuts. Tighten if necessary.
Tire rotation*Tires should be rotated every7,500 miles (12,000 km).
Wheel alignment and balanceIf 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.
Windshield wiper blades*Check for cracks
or wear if they do not wipe properly.
Doors and engine hoodCheck 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.
INSIDE THE VEHICLE
The maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.
Lights*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.
Warning lights and buzzers/chimesMake
sure that all warning lights and buzzers/chimes
are operating properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and
that the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly and
in good quantity when operating the heater or
air conditioner.

head restraints move up and down smoothly
and that the locks (if equipped) hold securely
in all latched positions.
Seat beltsCheck that all parts of the seat belt
system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly, and
are installed securely. Check the belt webbing
for cuts, fraying, wear or damage.
Accelerator pedalCheck 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.
BrakesCheck 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.
Check the brake booster function. Be sure to
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 ªParkº mechanismCheck that the brake pedal must be depressed
for the selector lever to be moved from the ªPº
position. On a fairly steep hill check that the
vehicle is held securely with the selector lever
in the ªPº position without applying any brakes.
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be
checked periodically (e.g. 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 hosesCheck 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 between
the ªMAXº and ªMINº lines on the reservoir.
Battery*Check the fluid level in each cell. It
should be between the ªMAXº and ªMINº lines.
Engine drive belts*Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*Check the level on thedipstick after parking the vehicle on a level
spot and turning off the engine. Be sure to wait
a few minutes to allow the oil to drain back into
the sump.
Power steering fluid level* and linesCheck
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 ªPº with the engine idling.
Exhaust systemMake 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 the carbon monox-
ide warning in the ªStarting and drivingº sec-
tion)
UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important 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. See the ªAppearance and interior
careº section for additional information.

remove cargo as necessary.
Loading tips
IThe GVW must not exceed GVWR or
GAWR as specified on the FMVSS Certifi-
cation Label.
IDo not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
IProperly secure all cargo to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
IDo not load your vehicle any heavier
than the GVWR or the maximum front
and rear GAWRs. If you do, parts on
your vehicle can break, or it can
change the way your vehicle handles.
This could result in loss of control
and cause personal injury.
IOverloading can shorten the life of
your vehicle. Failures caused by
overloading are not covered by yourwarranty.
Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer will place addi-
tional loads on your vehicle's engine, drive
train, steering, braking and other systems.
Information on trailer towing ability and the
special equipment required should be ob-
tained from your Nissan dealer. He can obtain
aNissan Trailer Towing Guidefor you.

Maximum load limits
Maximum trailer loads
Never allow the total trailer load to exceed
1,000 lb (454 kg). The total trailer load equals
trailer weight plus its cargo weight. Towing
loads greater than 1,000 lb (454 kg) or using
improper towing equipment could adversely
affect vehicle handling, braking and perfor-
mance.
Vehicle damage and/or personal injury
resulting from improper towing proce-
dures is not covered by NISSAN warran-
ties. Information on trailer towing and
required towing equipment should be
obtained from dealers who specialize in
providing trailers or other towing
equipment.
Tongue load
Keep the tongue load between 9 and 11% of
the total trailer load. If the tongue load be-
comes excessive, rearrange cargo to allow for
proper tongue load.Maximum gross vehicle weight/maximum
gross axle weight
The gross vehicle weight of the towing vehicle
must not exceed the gross vehicle weight
rating (GVWR) shown on the F.M.
V.S.S. certification label. The gross vehicle
weight equals the combined weight of the
unloaded vehicle, passengers, luggage, hitch,
trailer tongue load and any other optional
equipment. In addition, front or rear gross axle
weight must not exceed the gross axle weight
rating (GAWR) shown on the F.M.V.S.S. cer-
tification label.

Trailer hitch
Choose a proper hitch for your vehicle and
trailer. Make sure the trailer hitch is securely
attached to the vehicle, to help avoid personal
injury or property damage due to sway caused
by crosswinds, rough road surfaces or passing
trucks.
IDo not use axle-mounted hitches.
IThe hitch should not be attached to
or affect the operation of the impact-
absorbing bumper
IDo not modify the vehicle exhaust
system, brake system, etc. when the
hitch is installed.
ITo reduce the possibility of additional
damage if your vehicle is struck from
the rear, where practical, remove the
TI1012M

hitch when not in use. Remove the
receiver when not in use. After the
hitch is removed, seal the bolt holes
to prevent exhaust fumes, water or
dust from entering the passenger
compartment.
IRegularly check that all hitch mount-
ing bolts are securely mounted.
Tire pressures
IWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pressure
indicated on the tire placard (located on the
inside of the center console lid.)
ITrailer tire condition, size, load rating and
proper inflation pressure should be in ac-
cordance with the trailer and tire manufac-
turers' specifications.
Safety chain
Always use a suitable chain between your
vehicle and the trailer. The chain should be
crossed and should be attached to the hitch,
not to the vehicle bumper or axle. Be sure to
leave enough slack in the chain to permit
turning corners.
Trailer lights
Trailer lights should comply with Federal
and/or local regulations. When wiring the ve-
hicle for towing, connect the stop and tail light
pickup into the vehicle electrical circuit at a
point between the sensor and stop light or light
switch.
Trailer brakes
If your trailer is equipped with a braking sys-
tem, make sure it conforms to Federal and/or
local regulations and that it is properly in-
stalled.
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
IBe certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if
it has an abnormal nose-up or nose-down
condition; check for improper tongue load,
overload, worn suspension or other pos-
sible causes of either condition.
IAlways secure items in the trailer to preventload shifts while driving.
IBe certain your rear view mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing be-
fore driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding of
the vehicle's behavior, you should practice
turning, stopping and backing up in an area
which is free from traffic. Steering stability, and
braking performance will be somewhat differ-
ent than under normal driving conditions.
IAlways secure items in the trailer to prevent
load shift while driving.
IAvoid abrupt starts, acceleration or stops.
IAvoid sharp turns or lane changes.
IAlways drive your vehicle at a moderate
speed.
IAlways block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if you
must do so, and if your vehicle is equipped
with automatic transmission, first block the
wheels and apply the parking brake, and
then move the transmission shift lever into
the ªPº position. If you move the shift lever
to the ªPº position before blocking the
