Always follow the instructions below. Fail-
ure to do so could result in damage to the
charging system and cause personal in-
jury.
1. If the booster battery is in another vehicle,
position the two vehicles to bring their bat-
teries into close proximity to each other.
Do not allow the two vehicles to touch.
2. Apply parking brake. Move the shift lever to
ªNeutralº (On automatic transmission mod-
els, move the lever to ªPº). Switch off all
unnecessary electrical systems (light,
heater, air conditioner, etc.).3. Remove vent caps on the battery (if so
equipped). Cover the battery with an old
cloth to reduce explosion hazard.
4. Connect jumper cables in the sequence as
illustrated.
IAlways connect positive (+) to posi-
tive (+) and negative (þ) to body
ground (e.g., strut mounting bolt, etc.
Ð not to the battery).
IMake sure that cables do not touch
moving parts in the engine compart-
ment and that clamps do not contact
any other metal.
5. Start the engine of the other vehicle and let
it run for a few minutes.
6. Keep the engine speed of the other vehicle
at about 2,000 rpm, and start your engine in
the normal manner.
Do not keep starter motor engaged for
more than 10 seconds. If the engine
does not start right away, turn the key
off and wait 3 to 4 seconds before trying
again.

7. After starting your engine, carefully discon-
nect the negative cable and then the posi-
tive cable.
8. Replace the vent caps (if so equipped). Be
sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.
IAutomatic transmission models can-
not be push started. This may cause
transmission damage.
IThree-way catalyst equipped models
should not be started by pushing
since the three-way catalyst may be
damaged.
INever try to start the vehicle by tow-
ing it; when the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading), or
if you feel a lack of engine power, detect
abnormal noise, etc., take the following steps:
IDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
ITo avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
IDo not open the hood if steam is
coming out.
1. Move the vehicle safely off the road, apply
the parking brake and move the gearshift
lever to neutral (automatic transmission to
ªPº).
Do not stop the engine.
2. Turn off the air conditioner switch. Open all
the windows, move the heater or air condi-
tioner temperature control to ªmaximum

hotº and fan control to ªhigh speedº.
3. If engine overheating is caused by climbing
a long hill on a hot day, run the engine at a
fast idle (approximately 1,500 rpm) until the
temperature gauge indication returns to
normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. Wait until no
steam or coolant can be seen before pro-
ceeding.
5. Open the engine hood.
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or
looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water.
If coolant is leaking or the cooling fan does
not run, stop the engine.
IBe careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or to get caught in,
belts, or motor fan.
IThe fan motor can start at any time
when the coolant temperature is high.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the reservoir
tank if necessary. Have your vehicle re-
paired at the nearest NISSAN dealer.When towing your vehicle, all State (Provincial
in Canada) and local regulations for towing
must be followed. Incorrect towing equipment
could damage your vehicle. Towing instruc-
tions are available from your NISSAN dealer.
Local service operators will generally be famil-
iar with the applicable laws and procedures for
towing. To assure proper towing and to pre-
vent accidental damage to your vehicle, NIS-
SAN recommends that you have a service
operator tow your vehicle. It is advisable to
have the service operator carefully read the
following precautions.
INever ride in a vehicle that is being
towed.
INever get under your vehicle after it
has been lifted by a tow truck.
IWhen towing, make sure that the
transmission, axles, steering system
and power train are in working condi-
tion. If any unit is damaged, a dolly
must be used.

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.
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 ªPº
(Park).
IBe sure the ignition key is ªOFFº or
ªLOCKº when performing any parts
replacement or repairs.
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 ªOFFº
position and the engine is not run-
ning. To avoid injury, always discon-
nect the negative battery cable before
working near the fan.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 remove necktie and
any jewelry, such as rings, watches,
etc. before working 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.
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 the bat-
tery.
IThe 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.
IDo not work under the hood while the
engine 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. Improperly disposed motor oil
and/or other vehicle fluids can hurt
the environment. Always conform to
local regulations for disposal of ve-
hicle fluid.
This ªDo-it-yourself operationsº section gives
instructions regarding only those items which
are relatively easy for an owner to perform.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze solu-
tion contains rust and corrosion inhibitors,
therefore additional cooling system additives
are not necessary.
When adding or replacing coolant, be
sure to use only an ethylene glycol anti-
freeze with the proper mixture ratio of
50% anti-freeze and 50% distilled water.
The use of other types of coolant solu-
tions may damage your engine cooling
system.
