INever jack up the vehicle more than
necessary.
INever use blocks on or under the
jack.
IDo not start or run engine while ve-
hicle is on the jack, as it may cause
the vehicle to move. This is especially
true for vehicles with limited slid dif-
ferential carriers.
IDo not allow passengers to stay in
the vehicle while it is on the jack.
Installing the spare tire1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the wheel on and tighten the
wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel
nuts alternately and evenly until they are
tight.
4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence as illustrated.
IIncorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
IDo not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.As soon as possible tighten the wheel nuts
to the specified torque with a torque
wrench.

To start your engine with a booster battery, the
instructions and precautions below must be
followed.IIf done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.
IExplosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
the battery.
IDo not allow battery fluid to come
into contact with eyes, skin, cloth or
painted surfaces. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.
IKeep battery out of the reach of chil-
dren.
IThe booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.IWhenever working on or near a bat-
tery, always wear suitable eye protec-
tors (for example, goggles or indus-
trial safety spectacles) and remove
rings, metal bands, or any other jew-
elry. Do not lean over the battery
when jump starting.
IDo not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
IYour vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.JUMP STARTING

Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.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 tothe N (Neutral) position (On automatic
transmission models, move the selector
lever to the P (Park) position). 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 (for example, 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.
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.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:
1. Move the vehicle safely off the road, apply
the parking brake and move the shift lever
to the N (Neutral) position (automatic trans-
mission to the P (Park) position).
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 maximum hot

and fan control to high speed.
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 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 the
cooling fan, or drive belt.
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 are
generally familiar with the applicable laws and
procedures for towing. To assure proper tow-
ing and to prevent accidental damage to your
vehicle, NISSAN recommends having a ser-
vice 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 powertrain are in working condi-
tion. If any unit is damaged, dollies
must be used.TOWING YOUR VEHICLE

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
N (Neutral) position. For an automatic
transmission, move the selector lever
to P (Park) position.
IBe sure the ignition key is OFF or
LOCK when performing any parts re-
placement 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 OFF
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.
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.
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.
IOn 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.
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 ª8. Do-it-yourselfº section gives instruc-
tions 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
