TOWING RECOMMENDED BY
NISSAN
Two wheel drive modelsNISSAN recommends that your vehicle be
towed with the driving (rear) wheels off the
ground or place the vehicle on a flat bed truck
as illustrated.
CAUTION
INever tow automatic transmission
models with the rear wheels on the
ground or four wheels on the ground
(forward or backward), as this may
cause serious and expensive damage
to the transmission. If it is necessary
to tow the vehicle with the front
wheels raised, always use towing dol-
lies under the rear wheels.
IWhen towing automatic or manual
transmission models with the front
wheels on the ground or on towing
dollies:
ITurn the ignition key to the OFF
position, and secure the steeringwheel in a straightahead position
with a rope or similar device. Never
secure the steering wheel by turn-
ing the ignition key to the LOCK
position. This may damage the
steering lock mechanism.
IIf you have to tow manual transmis-
sion models with the rear wheels on
the ground or four wheels on the
ground (if you do not use towing
dollies):
IAlways release the parking brake.
IMove the transmission shift lever
to the N (Neutral) position.
IObserve the following restricted tow-
ing speeds and distances for manual
transmission models only:
ISpeed: Below 60 MPH (95 km/h)
IDistance: Less than 500 miles (800
km)
If the speed or distance must necessarily be
greater, remove the propeller shaft before tow-
ing to prevent damage to the transmission.

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.
WARNING
IPark 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 selector lever to the P
(Park) position.
IBe sure the ignition key is in the OFF
or LOCK position when performing
any replacement or repair.
IIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving fans
belts and any other moving parts.
IIt is advisable to secure or remove
any loose clothing and any jewelry,such as rings, watches, etc. before
working on your vehicle.
IAlways wear eye protection when-
ever you work on your vehicle.
IIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
INever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel and battery.
IYour 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 before
working near the fan.
IOn gasoline engine models with themultiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by a NISSAN dealer because
the fuel lines are under high pressure
even when the engine is off.
CAUTION
IDo not work under the engine hood
while it is hot. Turn off the engine and
wait until it cools down.
INever connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
INever leave the engine or the auto-
matic transmission related compo-
nent harness connector discon-
nected while the ignition key is on.
IAvoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant, and/or
other vehicle fluids can hurt the envi-

Check for leakage around the drain plug.
Correct as required.
9. Turn the engine off and wait more than 10
minutes. Check the oil level with the dip-
stick. Add engine oil if necessary.
WARNING
IProlonged and repeated contact withused engine oil may cause skin can-
cer.
ITry to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
IKeep used engine oil out of reach of
children.
CHANGING ENGINE OIL FILTER1. Park the vehicle on a level surface and
apply the parking brake.
2. Turn the engine off.

IKeep the battery surface clean and dry. Any
corrosion should be washed off with a
solution of baking soda and water.
IMake certain the terminal connections are
clean and securely tightened.
IIf the vehicle is not to be used for 30 days or
longer, disconnect the (Ð) negative battery
terminal cable to prevent discharge.
WARNING
IDo not expose the battery to flames
or electrical sparks. Hydrogen gas
generated by battery action is explo-
sive. Do not allow battery fluid to
contact your skin, eyes, fabrics, or
painted surfaces. After touching a
battery or battery cap, do not touch or
rub your eyes. Thoroughly wash your
hands. If the acid contacts your eyes,
skin or clothing, immediately flush
with water for at least 15 minutes and
seek medical attention.
IWhen working on or near a battery,
always wear suitable eye protection
and remove all jewelry.IBattery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after han-
dling.
IKeep the battery out of the reach of
children.
IDo not operate the vehicle if the fluid
in the battery is low. Low battery fluid
can cause a higher load on the bat-
tery which can generate heat, reduce
battery life, and in some cases lead to
an explosion.
JUMP STARTINGIf jump starting is necessary, see ªJump start-
ingº in the ª6. In case of emergencyº section. If
the engine does not start by jump starting, the
battery may have to be replaced. Contact your
NISSAN dealer.Check the fluid level in each cell. It should be
between the MAX. and MIN. lines.
If it is necessary to add fluid, add only distilled
water to bring the level to the indicator in each
filler opening.Do not overfill.
1. Remove the cell plugs using a suitable tool.
2. Add distilled water up to the MAX. level.
3. Tighten cell plugs.
