1996 NISSAN ALTIMA ignition

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 your
NISSAN dealer. Local service operators will
generally be familiar with the applicable
laws and procedures for towing. To assure
proper towing and to prevent accidental
damage to your vehicle, NISSAN recom-
mends that you have a service operator tow
your vehicle. It is advisable to have the
service operator carefully read the following
precautions.
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.
cWhen towing with the front wheels
on the ground:Turn the ignition key to the ``OFF''
position and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
place the ignition key in the ``LOCK''
position. This will result in damage
to the steering lock mechanism.
Move the gearshift lever to the Neu-
tral (``N'' position).
On automatic transmission models,
to move the shift lever to the Neutral
position, turn the ignition key to the
``ACC'' position. After moving the
shift lever to the Neutral position, be
sure to turn the ignition key to the
``OFF'' position.
c
When towing with the rear wheels on
the ground, release the parking brake.
On automatic transmission models,
to move the shift lever to the Neutral
position, turn the ignition key to the
``ACC'' position. After moving the
shift lever to the Neutral position, be
sure to turn the ignition key to the
``OFF'' position.
cAttach safety chains for all towing.NISSAN recommends that your vehicle be
towed with the driving (front) wheels off the
ground as illustrated.

When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
Neutral. For an automatic transmis-
sion, move the shift lever to ``P''
(Park).
cBe sure the ignition key is ªOFFº
when performing any parts replace-
ment or repairs.
cDo not work under the hood while the
engine is hot. Turn off the engine and
wait until it cools down.
cYour vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without warning,
even if the ignition key is in the ``OFF''
position and the engine is not run-
ning. To avoid injury, always discon-
nect the negative battery cable beforeworking near the fan.
cIf you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
cIt is advisable to remove ties and any
jewelry, such as rings, watches, etc.
before working on your vehicle.
cIf you must run the engine in an en-
closed space such as a garage, be
sure there is proper ventilation for
exhaust gases.
cNever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle, sup-
port it with safety stands.
cKeep smoking materials, flame and
sparks away from fuel and the battery.
cNever connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition is
on.
cOn gasoline engine models with the
Multiport Fuel Injection (MFI) system,
the fuel filter or fuel lines should be
serviced by a NISSAN dealer becausethe fuel lines are under high pressure
even when the engine is off.
cFailure to follow these or other com-
mon sense guidelines may lead to
serious injury or vehicle damage.
cImproperly disposed motor oil and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid. Avoid contact with used engine
oil.
This ``Do-it-yourself operations'' section
gives instructions regarding only those
items which are relatively easy for an owner
to perform.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by your NISSAN dealer.

Incorrect ignition timing will result in knock-
ing, after-run or overheating. This in turn
may cause excessive fuel consumption or
damage to the engine. If any of the above
symptoms are encountered, have your ve-
hicle checked at a NISSAN dealer or other
competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
no cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time under
heavy engine load.
ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to chose the correct quality
and viscosity oil to ensure satisfactory en-
gine life and performance. Nissan recom-
mends the use of a low friction oil (energy
conserving oil) in order to improve fuel
economy and conserve energy. Oils which
do not have the specified quality label
should not be used as they could cause
engine damage.Only those engine oils with the American
Petroleum Institute (API) CERTIFICATION
MARK on the front of the container should
be used. This type of oil supersedes the
existing API SG or SH and Energy Conserv-
ing II categories.
If you cannot find engine oil with the CER-
TIFICATION MARK, an API SG or SH and
Energy Conserving II oil with API Service
Symbol may be used. An oil with a single
designation ``SG'' or ``SH'', or in combina-
tion with other categories (for example,
``SG/CC'' or ``SG/CD'') may also be used if
one with the API CERTIFICATION MARK
