engine overheat NISSAN ALTIMA COUPE 2012 D32 / 4.G Owners Manual

TACHOMETER
The tachometer indicates engine speed in revo-
lutions per minute (rpm) . Do not rev engine into
the red zone
1.
CAUTION
When engine speed approaches the red
zone, shift to a higher gear or reduce en-
gine speed. 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
1when the gauge needle points
within the zone shown in the illustration.
The engine coolant temperature varies with the
outside air temperature and driving conditions.
CAUTION
If the gauge indicates coolant tempera-
ture near the hot (H) end of the normal
range, reduce vehicle speed to decrease
temperature. If the gauge is over the nor-
mal range, stop the vehicle as soon as
safely possible. If the engine is over-
heated, continued operation of the ve-
hicle may seriously damage the engine.
See “If your vehicle overheats” in the “In
case of emergency” section for immediate
action required.

A/C may be used for quick cooling.
Dehumidified heating
This mode is used to heat and dehumidify the air.
1. Press the
button to the OFF position.
2. Press the
air flow control button.
3. Turn the fan control dial to the desired posi- tion.
4. Push the
button. 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. Press the
air flow control button.
2. Turn the fan control dial to the desired posi- tion. ●
When the
orare selected, the
air conditioner automatically turns on (the
indicator light will illuminate) if the outside
temperature is more than 36°F (2°C) . 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.
3. Turn the temperature control dial to the de- sired position.
Operating tips
●Keep the windows and moonroof closed
while the air conditioner is in operation.
● After 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.
● The 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. ●
A visible mist may be seen coming from the
ventilators in hot, humid conditions as the air
is cooled rapidly. This does not indicate a
malfunction.
● If 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.
AIR FLOW CHARTS
The following charts show the button and dial
positions for MAXIMUM AND QUICK heating,
cooling or defrosting. The air recirculation
button should always be in the OFF posi-
tion for heating and defrosting.

CAUTION
●Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
● Keep 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.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability. Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Starting and driving5-3

The power assisted steering uses 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
harder to operate.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at 2 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 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.
WARNING
●
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
● If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
Parking brake break-in
Break-in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drum/rotors are replaced, in order to assure the
best brake performance.
This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.

CAUTION
●Always connect positive () to positive
() and negative () to body ground (for
example, strut mounting bolt, engine
lift bracket, etc.) — not to the battery.
● Make 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.
CAUTION
●Do not push start this vehicle. The
three-way catalyst may be damaged.
● Continuously Variable Transmission
(CVT) models cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage.
● For manual transmission (M/T) models,
never 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
●
Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
● To 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.
● Do 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 selector
to N (Neutral) (manual transmission) or to P
(Park) (CVT) .
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air conditioner
temperature control to maximum hot and fan
control to high speed.
PUSH STARTING IF YOUR VEHICLE OVERHEATS

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Engine Coolant (blue) and 50% water
to provide year-round anti-freeze and coolant
protection. The anti-freeze solution contains rust
and corrosion inhibitors. Additional engine cool-
ing system additives are not necessary.
WARNING
●Never remove the radiator or coolant
reservoir 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 precautions in “If your
vehicle overheats” found in the “In case
of emergency” section of this manual.
● The radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, use only a genuine
NISSAN radiator cap.
CAUTION
● Never use any additives in the coolant
such as radiator sealer in the cooling
system. This may cause damage to
electrical equipment such as the motor
and inverter.
● When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to -34°
F (-37° C) . If additional freeze protec-
tion is needed due to weather where
you operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the direc-
tions on the container. If an equivalent
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) is
used, follow the coolant manufacturer’s
instructions to maintain minimum anti-
freeze protection to -34° F (-37° C) . The
use of other types of coolant solutions
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling
system. ●
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km) or
7 years. Mixing any other type of cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) , includ-
ing Genuine NISSAN Long Life
Antifreeze/Coolant (green) , or the use
of non-distilled water will reduce the
life expectancy of the factory-fill cool-
ant. Refer to the Nissan Service and
Maintenance Guide for more details.
ENGINE COOLING SYSTEM
8-8Maintenance and do-it-yourself

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
B, add coolant to the MAX level
A. If the reservoir is empty, check the coolant
level in the radiator when 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
A. This vehicle contains Genuine NISSAN Long Life
Antifreeze/Coolant (blue) . The life expectancy of
the factory-fill coolant is 105,000 miles (168,000
km) or 7 years. Mixing any other type of coolant or
the use of non-distilled water will reduce the life
expectancy of the factory-fill coolant. Refer to the
NISSAN Service and Maintenance Guide for
more details.
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
●
To avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
● Never remove the radiator cap when the
engine is hot. Serious burns could be
caused by high pressure fluid escaping
from the radiator.
● Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
● Keep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
