engine overheat NISSAN XTERRA 2004 WD22 / 1.G Owners Manual

TACHOMETER
The tachometer indicates engine speed in revo-
lutions per minute (r/min) . The red zone
s1is
shown in the illustration.
CAUTION
When engine speed approaches the red
zone, shift to a higher gear. Operating the
engine in the red zone may cause serious
engine damage.
ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant tempera-
ture. The engine coolant temperature is within the
normal range when the gauge needle points be-
tween the C and the H on the gauge.
The engine coolant temperature varies with the
outside air temperature and driving conditions.
CAUTION
If the gauge indicates engine coolant tem-
perature over the normal range, stop the
vehicle as soon as safely possible. If the
engine is overheated, continued opera-
tion of the vehicle may seriously damage
the engine. See “If your vehicle over-
heats” in the “In case of emergency” sec-
tion for immediate action required.

3. Push thebutton. The indicator light
comes on.
When the
,or positions in between
are selected, the air conditioner automatically
turns on (however, the indicator light will not
illuminate) if the outside temperature is more than
36°F (2°C) . The air conditioning system will con-
tinue to operate until the fan control dial is turned
to OFF or the vehicle is shut off, even if the air flow
control dial is turned to a position other than
the
position. This dehumidifies the air
which helps defog the windshield. The
mode automatically turns off, allowing outside air
to be drawn into the passenger compartment to
further improve the defogging performance.
4. Turn the temperature control dial to the de-
sired position.
Operating tips
cKeep the windows and sunroof (if so
equipped) closed while the air conditioner is
in operation.cAfter parking in the sun, drive for 2 or 3
minutes with the windows open to vent hot
air from the passenger compartment. Then,
close the windows. This allows the air con-
ditioner to cool the interior more quickly.
cThe air conditioning system should be
operated for approximately 10 minutes
at least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
cIf the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. See “If your
vehicle overheats” in the “In case of
emergency” section of this manual.

CAUTION
cDo not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
cKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
cAvoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
cDo not race the engine while warming it
up.
cDo not push or tow your vehicle to start
the engine.
LOW TIRE PRESSURE WARNING
SYSTEM
The low tire pressure warning system monitors
tire pressure of all tires (except the spare tire) .
The low tire pressure warning system will activate
only when the vehicle is driven at speeds above
20 MPH (32 km/h) . Also, this system may not
detect a sudden drop in tire pressure (for ex-
ample a flat tire while driving) .
Tire pressure rises and falls depending on the
heat caused by the vehicle’s operation and the
outside temperature. Low outside temperature
can lower the temperature of the air inside the tire
which can cause a lower tire inflation pressure.
This may cause the low tire pressure warning
light to illuminate.
If the warning light illuminates in low ambient
temperature as described above, check the tire
pressure for all four tires. Adjust the tire pressure
to the recommended COLD tire pressure shown
on the tire placard to turn the low tire pressure
warning light OFF.
Frequently check the tire pressure and adjust
pressure of each tire properly.
Low tire pressure warning
If the vehicle is being driven with very low tire
pressure (lower than 28 psi, 193 kPa) , the lowtire pressure warning light comes on and the
chime sounds for about 10 seconds.
For additional information regarding the above
warning, see “Warning/indicator lights and au-
dible reminders” in the “Instruments and con-
trols” section.
WARNING
cIf the low tire pressure warning light
flashes while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Serious vehicle
damage could occur and may lead to an
accident and could result in serious
personal injury. Check the tire pressure
for all four tires. Adjust the tire pressure
to the recommended COLD tire pres-
sure shown on the tire placard to turn
the low tire pressure warning light OFF.
If you have a flat tire, replace it with a
spare tire as soon as possible. (See
“Flat tire” in the “In case of emergency”
section for changing a flat tire.)

DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol
or drugs. Alcohol in the bloodstream re-
duces coordination, delays reaction time
and impairs judgement. Driving after
drinking alcohol increases the likelihood
of being involved in an accident injuring
yourself and others. Additionally, if you
are injured in an accident, alcohol can
increase the severity of the injury.
NISSAN is committed to safe driving. However,
you must choose not to drive under the influence
of alcohol. Every year thousands of people are
injured or killed in alcohol-related accidents. Al-
though the local laws vary on what is considered
to be legally intoxicated, the fact is that alcohol
affects all people differently and most people
underestimate the effects of alcohol.
Remember, drinking and driving don’t mix! And
that is true for drugs, too (over-the-counter, pre-
scription, and illegal drugs) . Don’t drive if your
ability to operate your vehicle is impaired by alco-
hol, drugs, or some other physical condition.
DRIVING SAFETY PRECAUTIONS
Your NISSAN is designed for both normal and
off-road use. However, avoid driving in deep wa-
ter or mud as your NISSAN is mainly designed for
leisure use, unlike a conventional off-road ve-
hicle.
Remember that two-wheel drive models are less
capable than four-wheel drive models for rough
road driving and extrication when stuck in deep
snow or mud, or the like.
Please observe the following precautions:
WARNING
cDrive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle
should be seated with their seat belt
fastened. This will keep you and your
passengers in position when driving
over rough terrain.
cDo not drive across steep slopes. In-
stead drive either straight up or straight
down the slopes. Off-road vehicles can
tip over sideways much more easily
than they can forward or backward.cMany hills are too steep for any vehicle.
If you drive up them, you may stall. If
you drive down them, you may not be
able to control your speed. If you drive
across them, you may roll over.
cDo not shift gears while driving on
downhill grades as this could cause
loss of control of the vehicle.
cStay alert when driving to the top of a
hill. At the top there could be a drop-off
or other hazard that could cause an
accident.
cIf your engine stalls or you cannot make
it to the top of a steep hill, never at-
tempt to turn around. Your vehicle
could tip or roll over. Always back
straight down in R (Reverse) gear. Never
back down in N (Neutral) or with the
clutch depressed (manual transmission
vehicles) , using only the brake, as this
could cause loss of control.
cHeavy braking going down a hill could
cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed.

1. Firmly apply the parking brake.
2.Manual transmission models:
Place the shift lever in the R (Reverse) posi-
tion. When parking on an uphill grade, place
the shift lever in 1st gear.
Automatic transmission models:
Move the shift selector lever to the P (Park)
position.
3. To help prevent the vehicle from rolling into
traffic 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 cen-
ter of the road if it moves.
4. Turn the ignition key to the LOCK position
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 the drive belt breaks, you
will still have control of the vehicle. However,
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 hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE 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 dis-
tance 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. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.

CAUTION
cAlways connect positive (1) to positive
(1) and negative (2) to body ground (for
example, strut mounting bolt, engine
lift bracket, etc.) — not to the battery.
cMake sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal.
5. Start the engine of the booster vehicle and
let it run for a few minutes.
6. Keep the engine speed of the booster ve-
hicle at about 2,000 rpm, and start the en-
gine of the vehicle being jump started.
CAUTION
Do not keep the 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 the engine, carefully discon-
nect the negative cable and then the positive
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.
WARNING
cAutomatic transmission models cannot
be push-started or tow-started. This
may cause transmission or other ve-
hicle damage.
cThree-way catalyst equipped models
should not be started by pushing. The
three-way catalyst may be damaged.
cNever try to start the vehicle by towing
it. When the engine starts, the forward
surge could cause the vehicle 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.
WARNING
cDo not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or 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 com-
ing out.
1. Move the vehicle safely off the road, apply
the parking brake and move the shift lever to
N (Neutral) (manual transmission) or to P
(Park) (automatic transmission) .
Do not stop the engine.
2. Turn off the air conditioner (if so equipped) .
Open all the windows, move the heater or air
conditioner 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 r/min) until the
temperature gauge indicator returns to nor-
mal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. Do not open the
hood further until no steam or coolant can be
seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, 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,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or 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 cool-
ant level in the engine coolant reservoir tank
with the engine running. Add coolant to the
engine coolant reservoir tank if necessary.
Have your vehicle repaired at a NISSAN
dealer.When towing your vehicle, all State (Provincial in
Canada) and local regulations for towing must be
followed. Incorrect towing equipment could dam-
age your vehicle. Towing instructions are avail-
able from a NISSAN dealer. Local service opera-
tors are generally familiar with the applicable laws
and procedures for towing. To assure proper
towing and to prevent accidental damage to your
vehicle, NISSAN recommends having a service
operator tow your vehicle. It is advisable to have
the service operator carefully read the following
precautions:
WARNING
cNever ride in a vehicle that is being
towed.
cNever get under your vehicle after it has
been lifted by a tow truck.

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze cool-
ant solution. The anti-freeze solution contains
rust and corrosion inhibitors; therefore, additional
engine cooling system additives are not neces-
sary.
WARNING
cNever remove the radiator cap when the
engine is hot. Wait until the engine and
radiator cool down. Serious burns
could be caused by high pressure fluid
escaping from the radiator. See precau-
tions in “If your vehicle 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 en-
gine damage, use only a genuine
NISSAN radiator cap.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold.If the coolant level is below
the MIN level, add coolant to the MAX level. If the
reservoir 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 up to the MAX level.
If the cooling system frequently requires
coolant, have it checked by a NISSAN
dealer.

CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine coolant.
The service procedure can be found in the
NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
cTo avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
cNever remove the radiator cap when the
engine is hot. Serious burns could be
caused by high pressure fluid escaping
from the radiator.
cAvoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
cKeep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply
the parking brake.
2. Start the engine and let it idle until it reaches
operating temperature.3. Turn off the engine.Wait more than 10
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Re-
insert it all the way.
5. Remove the dipstick again and check the oil
level. It should be between the H (High) and
L (Low) marks. This is the normal operating
oil level range. If the oil level is below the L
(Low) mark, remove the oil filler cap and pour
recommended oil through the opening.Do
not overfill.

Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
Aftermarket fuel additives
NISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel injec-
tor cleaner, octane booster, intake valve deposit
removers, 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 (super-
charger ) AKI (Anti-Knock Index) . However, you
may use unleaded gasoline with an octane rating
as low as 85 AKI (Anti-Knock Index) number in
high altitude areas [over 4,000 ft (1,219 m)] such
as: Colorado, Montana, New Mexico, Utah, Wyo-
ming, northeastern Nevada, southern Idaho,
western South Dakota, western Nebraska, 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 se-
vere, 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 a NISSAN dealer correct the
condition. Failure to correct the condition
is misuse of the vehicle, for which NISSAN
is not responsible.
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 symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
