2003 NISSAN ALTIMA engine overheat

ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant tempera-
ture. The engine coolant temperature is within the
normal range
s1when the gauge needle points
between 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.

4. Push thebutton. The indicator light
comes on.
5. Turn the temperature control dial to the de-
sired position.
Dehumidified defogging
This mode is used to defog the windows and
dehumidify the air.
1. Turn the air flow control dial to the
position.
2. Turn the fan control dial to the desired posi-
tion.
3. Push the
button. 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 - 37°F (2 - 3°C) . The air conditioning system
will continue 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 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.
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 ma-
neuvers, because these driving practices could
cause you to lose control of your vehicle.As with
any vehicle, loss of control could result in a
collision with other vehicles or objects, or
cause the vehicle to roll over, 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 pre-
scription or over-the-counter drugs which may
cause drowsiness) . Always wear your seat belt
as outlined in the “Safety – Seats, seat belts and
supplemental air bags” section of this manual,
and also instruct your passengers to do so.
Seat belts help reduce the risk of injury in colli-
sions and rollovers.In a rollover crash, an
unbelted person is significantly more likely
to die than a person wearing a seat belt.
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.

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.

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 a ve-
hicle 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. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Wait
until no steam or coolant can be seen before
proceeding.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. 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.6. After the engine cools down, check the cool-
ant level in the reservoir tank with the engine
running. Add coolant to the reservoir tank if
necessary. Have your vehicle repaired at a
NISSAN dealer.

FLAT TOWING
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a vehicle
behind a recreational vehicle, such as a motor
home.
CAUTION
cFailure to follow these guidelines can
result in severe transmission damage.
cWhenever flat towing your vehicle, al-
ways tow forward, never backward.cDO NOT tow any automatic transmis-
sion vehicle with all four wheels on the
ground (flat towing) . Doing so WILL
DAMAGE internal transmission parts
due to lack of transmission lubrication.
cFor emergency towing procedures refer
to “Towing recommended by NISSAN”
in the “In case of emergency” section of
this manual.
Automatic Transmission
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dollyMUST
be placed under the towed vehicle’s drive
wheels.Alwaysfollow the dolly manufacturer’s
recommendations when using their product.
Manual Transmission
cAlways tow with the manual transmission in
Neutral.
cAfter towing 500 miles, start and idle the
engine with the transmission in Neutral for
two minutes. Failure to idle the engine after
every 500 miles of towing may cause dam-
age to internal transmission parts.
