2002 NISSAN FRONTIER engine overheat

TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (r/min).
CAUTION
When engine speed approaches the
red zone, shift to a higher gear. Oper-
ating the engine in the red zone may
cause serious engine damage.
ENGINE COOLANT TEMPERA-
TURE GAUGE
The gauge indicates the engine coolant
temperature.
The engine coolant temperature varies with
the outside air temperature and driving con-
ditions.
CAUTION
If the gauge indicates engine coolant
temperature over the normal range,
stop the vehicle as soon as safely pos-
sible. If the engine is overheated, con-
tinued operation of the vehicle may
seriously damage the engine. See the
``In case of emergency'' section for
immediate action required.

Dehumidfied heating
This mode is used to heat and dehumidfy
the air.
1. Push the
button to the off position.
2. Turn the air control dial to the
posi-
tion.

This mode is used to defog the windows
and dehumidify the air.
1. Turn the air control dial to the
posi-
tion.
cWhen the
,or positions in be-
tween are selected, the air conditioner
automatically turns on (however, the in-
dicator light will not illuminate) if theoutside temperature is more than 45ÉF
(7ÉC). This dehumidifies the air which
helps defog the windshield. The
mode automatically turns off, al-
lowing outside air to be drawn into the
passenger compartment to further im-
prove the defogging performance.
2. Turn the fan control dial to the desired
position.
3. Turn the temperature control dial to the
desired position.
Operating tips
cKeep windows and sunroof closed while
the air conditioner is in operation.
cAfter parking in the sun, drive for two or
three minutes with the windows open to
vent hot air from the passenger compart-
ment. Then, close the windows. This
allows the air conditioner to cool the
interior more quickly.
cThe air conditioning system should be
operated for approximately ten min-
utes at least once a month. This helps
prevent damage to the system due to
lack of lubrication.
cIf the engine coolant temperaturegauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. See(If your
vehicle overheats(in the(In case of

CAUTION
cDo not use leaded gasoline. Depos-
its from leaded gasoline seriously
reduce the three-way catalyst's abil-
ity to help reduce exhaust pollut-
ants.
cKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause over-
rich fuel flow into the three-way cata-
lyst, causing it to overheat. Do not
keep driving if the engine misfires,
or if noticeable loss of performance
or other unusual operating condi-
tions are detected. Have the vehicle
inspected promptly by an authorized
NISSAN dealer.
cAvoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.
cDo not race the engine while warm-
ing it up.
cDo not push or tow your vehicle to
start the engine.ON-PAVEMENT AND OFFROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly
higher rollover rate than other types of
vehicles.
They have higher ground clearance than
passenger cars to make them capable of
performing in a variety of on-pavement and
off-road applications. This gives them a
higher center of gravity than ordinary cars.
An advantage of higher ground clearance is
a better view of the road, allowing you to
anticipate problems. However, they are not
designed for cornering at the same speeds
as conventional two-wheel drive vehicles
any more than low-slung sports cars are
designed to perform satisfactorily under off-
road conditions. If at all possible, avoid
sharp turns or abrupt maneuvers particu-
larly at high speeds. As with other vehicles
of this type, failure to operate this vehicle
correctly may result in loss of control or
vehicle rollover.
Be sure to read the driving safety precau-
tions later in this section.
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers, because these driving
practices could cause you to lose control of
your vehicle.As with any vehicle, a loss
of control could result in a collision with
other vehicles or objects, or cause the
vehicle to rollover, particularly if the loss
of control causes the vehicle to slide
sideways.Be attentive at all times, and
avoid driving when tired. Never drive when
under the influence of alcohol or drugs
(including prescription or over-the-counter
drugs which may cause drowsiness). Al-
ways wear your seat belt as outlined in the
9Seats, restraints and supplemental air bag
systems9section of this manual, and also
instruct your passengers to do so.
Seat belts help reduce the risk of injury in

Place the shift lever in the R (Reverse)
position. When parking on an uphill
grade, place the shift lever in the 1st
position.
Automatic transmission models:
Move the selector lever to the P (Park)
position.
3. To help prevent the vehicle from rolling
into the street when parked on an incline,
it is a good practice to turn the wheels as
illustrated.
cHEADED DOWNHILL WITH CURB:
s1
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
cHEADED UPHILL WITH CURB:
s2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
cHEADED UPHILL OR DOWNHILL, NO
CURB:
s3
Turn the wheels toward the side of the
road so the vehicle will move away from
the center of the road if it moves.
4. Turn the ignition key to the LOCK posi-
tion and remove the key.The power assisted steering is designed to
use a hydraulic pump, driven by the engine,
to assist steering.
If the engine stops or drive belt breaks, you
will still have control of the vehicle. How-
ever, much greater steering effort is
needed, especially in sharp turns and at low
speeds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be much harder to operate.The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking at two wheels.
BRAKING PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on
the brake pedal will be required to stop the
vehicle and stopping distance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake linings and pads faster,
and reduce gas mileage.
To help reduce brake wear, and to prevent
the brakes from overheating, reduce speed
and downshift to a lower gear before going
down a slope or long grade.

If your vehicle is overheating (indicated by
an extremely high temperature gauge read-
ing), or if you feel a lack of engine power, or
detect abnormal noise, etc., take the follow-
ing steps:
WARNING
cDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
cTo avoid the danger of being
scalded, 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.
cDo not open the hood if steam is
coming out.
1. Move the vehicle safely off the road,
apply the parking brake and move the
shift lever to N (Neutral). On automatic
transmission models, move the selector
lever to P (Park).
Do not stop the engine.
2.
Turn off the air conditioner (if so
equipped). Open all of the windows,move the heater or air conditioner tem-
perature control to maximum hot and fan
control to high speed.
3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 r/min)
until the temperature gauge indicator re-
turns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. Wait until
no steam or coolant can be seen before
proceeding.
5. Open the hood.
WARNING
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 radia-
tor should not leak water. If coolant is
leaking, or the water pump belt is missing
or loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or to get caught in, engine belts or
the engine cooling fan. The engine
cooling fan 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 res-
ervoir tank if necessary. Have your ve-
hicle repaired at an authorized NISSAN
dealer.

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

WARNING
cNever remove the radiator cap when
the engine is hot. Wait until the en-
gine and radiator cool down. Serious
burns could be caused by high pres-
sure fluid escaping from the radia-
tor. See precautions in ``If your ve-
hicle overheats'' found in the ``In
case of emergency'' section of this
manual.
cThe radiator is equipped with a pres-
sure type radiator cap. To prevent
engine damage, use only a genuine
NISSAN radiator cap.
CHECKING ENGINE COOLANT
LEVEL
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level
is below the MIN level, add coolant to the
MAX 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 MAX level.

ZX

If any driveability problems such as engine
stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels,
immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygen-
ates can cause paint damage.
After Market Fuel Additives
NISSAN does not recommend the use of
any fuel additives (i.e., fuel injector cleaner,
octane booster, intake valve deposit remov-
ers, etc.) which are sold commercially.
Many of these additives intended for gum,
varnish or deposit removal may contain
active solvents or similar ingredients that
can be harmful to the fuel system and
engine.
Octane rating tips
In most parts of North America, you should
use unleaded gasoline with an octane rating
of at least 87 (except supercharger) or 91
(supercharger) AKI (Anti-Knock Index).
However, for non-supercharged vehicles
only, you may use unleaded gasoline with
an octane rating as low as 85 AKI in high
altitude areas (over 4,000 ft [1,219 m]) suchas: Colorado, Montana, New Mexico, Utah,
Wyoming, northeastern Nevada, southern
Idaho, western South Dakota, western Ne-
braska, and the part of Texas which is
directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy ``spark knock.'' (``Spark
knock'' is a metallic rapping noise.) If
severe, this can lead to engine damage. If
you detect a persistent heavy spark
knock even when using gasoline of the
stated octane rating, or if you hear steady
spark knock while holding a steady speed
on level roads, have an authorized
NISSAN dealer correct the condition. Fail-
ure to correct the condition is misuse of
the vehicle, for which NISSAN is not re-
sponsible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which
may cause excessive fuel consumption or
engine damage. If any of the above symp-
toms are encountered, have your vehicle
checked at an authorized NISSAN dealer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This isno cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time under
heavy engine load.
