If you have a flat tire, follow the instructions
below.
Stopping the vehicle
1. Safely move the vehicle off the road away
from traffic.
2. Turn on the hazard warning flasher.
3. Park on a level surface and apply the
parking brake. Shift the manual transmis-
sion into reverse (automatic transmission in
ªPº).
The transfer control lever must
be in the ª2Hº, ª4Hº or ª4Lº position.
Never place it in the ªNº position. Oth-
erwise, the vehicle could roll unexpect-
edly even if the manual transmission is
in gear or the automatic transmission is
in the ªPº position.
4. Turn off the engine.
IMake sure that the parking brake is
securely applied and the manual
transmission is shifted into reverse
(automatic transmission in ªPº).
INever change tires when the vehicle
is on a slope, ice or a slippery area.
This is dangerous.
INever change tires if oncoming traffic
is close to your vehicle. Wait for pro-
fessional road assistance.
IRaise the hood to warn other traffic
and to signal professional road assis-
tance personnel that you require as-
sistance.
IHave all passengers get out of the
vehicle and stand in a safe place
away from traffic and clear of the
vehicle.
Blocking wheels
Place suitable blocks at both the front and
back of the wheel diagonally opposite the flat
tire.
Be sure to block the wheel as the vehicle
may move and could cause personal
injury.

jack.
IDo not start or run engine while ve-
hicle is on the jack.
IDo not allow passengers to stay in
the vehicle while it is on the jack.IDo not raise the vehicle using a
bumper jack.
INever run the engine with the wheels
off the ground. It may cause the ve-
hicle to move. This is especially true
for vehicles with limited slip differen-
tial carriers.

If you try to start your engine with a booster
battery, follow the instructions and precautions
below:
IIf done incorrectly, jump starting can
be hazardous.
IExplosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
it.
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.
IA battery rated at above 12 volts
should not be used for a booster.
IWhenever working on or near a bat-
tery, always wear suitable eye protec-
tors (e.g., goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other metal jewelry.IKeep battery out of the reach of
children.
Always follow the instructions below
exactly. Failure to do so could result in
damage to the charging system and
cause personal injury.
1. Position the two vehicles to bring their
batteries into close proximity to each other
if the booster battery is in another vehicle.
Do not allow the two vehicles to touch.
2. Apply parking brakes. Move the shift lever
to ªNeutral positionº (On automatic trans-

mission models, move the lever to ªPº).
Switch off all unnecessary electrical sys-
tems (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.
IPositive (+) to positive (+) and nega-
tive (þ) to body ground, engine lift
bracket, etc. (not to the battery).
IMake sure that cables do not touch
any moving parts in the engine com-
partment and that clamps do not con-
tact 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 started by pushing. 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:
To avoid the danger of being burned,
never remove the radiator cap while the
engine is still hot. When the radiator cap
is removed, pressurized hot water will
spurt out, possibly causing serious
injury.
1. Move the vehicle safely off the road, apply
the parking brake and move the gearshift
lever to the neutral position (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. 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.4. Open the engine hood.
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. 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.
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.
IBe careful not to allow your hands,
hair or clothing to come into contact
with, or to get caught in, the running
fan or belts.
IIf coolant is leaking, the cooling fan
belt is missing or loose or the cooling
fan does not run, stop the engine.
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 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 vehicle from mov-
ing. For a manual transmission, move
the shift lever to Neutral. For an auto-
matic transmission, move the shift lever
to ªPº (Park).
IBe sure the ignition key is in the ªOFFº
or ªLOCKº position when performing
any replacement or repair.
IDo not work under the engine hood
while it is hot. Always turn off the engine
and wait until it cools down.
IIf you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans and
fan belts.
IIt is advisable to remove necktie and any
jewelry, such as rings, watch, etc. before
working on your vehicle.
IIf you must run the engine in an en-
closed space such as a garage, be surethere is proper ventilation for exhaust
gases.
INever get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel and battery.
INever connect or disconnect either the
battery or any transistorized component
connector while the ignition key is on.
IAlways apply the parking brake and
block the wheels to prevent the vehicle
from moving.
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.
IFailure to follow these or other common
sense guidelines may lead to serious
injury or vehicle damage.
IImproperly disposed motor oil and/or
other vehicle fluids can hurt the environ-
ment. Always conform to local regula-
tions for disposal of vehicle fluid.
IAvoid direct contact with used engine
oil.This ªDo-it-yourself operationsº section gives
instructions regarding only those items which
are relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect your warranty coverage.If in doubt about
any servicing, have it done by your NISSAN
dealer.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution (anti-freeze/water mix-
ture ratio: 50/50) which will ensure protection
against freezing down to þ30ÉF (þ35ÉC). The
anti-freeze solution contains rust and corro-
sion inhibitors, therefore additional cooling
system additives are not necessary.
When adding or replacing the coolant,
be sure to use an ethylene glycol anti-
freeze with the proper mixture ratio of
50% anti freeze 50% soft water.

The radiator is equipped with a pressure cap.
Use a NISSAN genuine cap or its equivalent
when replacement is required.
Never remove the radiator cap when theengine is hot; serious burns could be
caused by high pressure fluid escaping
from the radiator. Wait until the engine and
radiator cool down.Serious burns could be
caused by high pressure fluid escaping from
the radiator. See precautions in ªIf your vehicle
overheatsº found in the ªIn case of emergencyº
section.
CHECKING COOLANT LEVEL
With coolant reservoir
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below the ªMINº level, add coolant to the
ªMAXº level. If the reservoir tank is empty,
check the coolant level in the radiatorwhen
the engine is cold.If there is insufficient
coolant in the radiator, fill the radiator with
coolant up to the filler opening and also add it
to the reservoir tank up to the ªMAXº level.
