2012 NISSAN ARMADA engine overheat

WARNING
Do not push start this vehicle. The three-
way catalyst may be damaged.
CAUTION
Automatic transmission models cannot
be push-started or tow-started. Attempt-
ing to do so may cause transmission
damage.
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 or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant reser-
voir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
● Do not open the hood if steam is com-
ing out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading and
the illumination of the engine oil pressure/engine
coolant temperature high indicator light) , or if you
feel a lack of engine power, detect abnormal
noise, etc. take the following steps. 1. Move the vehicle safely off the road, apply the parking brake and move the shift selector
to P (Park) .
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. 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.) Do not
open the hood further until no steam or
coolant can be seen.
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.
PUSH STARTING IF YOUR VEHICLE OVERHEATS
6-10In case of emergency

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round anti-freeze and
coolant protection. The antifreeze solution con-
tains rust and corrosion inhibitors. Additional en-
gine cooling 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 cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause
damage to the engine, transmission
and/or cooling system.
● 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
Maintenance and do-it-yourself8-7

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
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. 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.
The engine coolant reservoir is a pressur-
ized tank. When installing the cap, tighten
it until a clicking sound is heard.
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 or engine
coolant reservoir 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.

8-8Maintenance and do-it-yourself

Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
E–85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV) . Do
not use E-85 in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square, orange
and black label with the common abbreviation or
the appropriate percentage for that region.
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
Using unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy “spark knock.” (“Spark
knock” is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If youdetect 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.
CAUTION
●
Your vehicle is not designed to run on
E-85 fuel. Using E-85 fuel in a vehicle
not specifically designed for E-85 fuel
can damage fuel system components
and is not covered by the NISSAN new
vehicle limited warranty. ●
E-85 is a mixture of approximately 85%
fuel ethanol and 15% unleaded
gasoline.
● U.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and
black label with the common abbrevia-
tion or the appropriate percentage for
that region.
FLEXIBLE FUEL VEHICLE (FFV) FUEL
RECOMMENDATION (if so equipped)
Your vehicle is designed to use (E-85) Fuel Etha-
nol, “Regular” unleaded regular gasoline or any
percentage of the two fuels combined.
U.S. government regulations require Fuel
Ethanol dispensing pumps to have a small,
square, orange and black label with the
common abbreviation or the appropriate
percentage for that region.
CAUTION
Use of other fuels such as Fuel Methanol
may cause powertrain damage or a loss of
vehicle performance.
Technical and consumer information9-5

Temperature conditions can also affect towing.
For example, towing a heavy trailer in high outside
temperatures on graded roads can affect engine
performance and cause overheating. The engine
protection mode, which helps reduce the chance
of engine damage, could activate and automati-
cally decrease engine power. Vehicle speed may
decrease under high load. Plan your trip carefully
to account for trailer and vehicle load, weather
and road conditions.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic,
which could increase the chance of a col-
lision. Be especially careful when driving.
If the vehicle cannot maintain a safe driv-
ing speed, pull to the side of the road in a
safe area. Allow the engine to cool and
return to normal operation. See “If your
vehicle overheats” in the “In case of emer-
gency” section of this manual.
CAUTION
Vehicle damage resulting from improper
towing procedures is not covered by
NISSAN warranties.
Tongue load
When using a weight carrying or a weight distrib-
uting hitch, keep the tongue load between 10 -
15 percent of the total trailer load or use the
trailer tongue load specified by the trailer manu-
facturer. The tongue load must be within the
maximum tongue load limits shown in the follow-
ing “Towing Load/Specification” chart. If the
tongue load becomes excessive, rearrange cargo
to allow for proper tongue load.
Maximum Gross Vehicle Weight
(GVW)/maximum Gross Axle Weight
(GAW)
The GVW of the towing vehicle must not exceed
the Gross Vehicle Weight Rating (GVWR)
shown on the F.M.V.S.S./C.M.V.S.S. certification
label. The GVW equals the combined weight of
the unloaded vehicle, passengers, luggage,
hitch, trailer tongue load and any other optional
equipment. In addition, front or rear GAW must
not exceed the Gross Axle Weight Rating
(GAWR) shown on the F.M.V.S.S./C.M.V.S.S.
certification label.

Trailer towing tips
In order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability and braking perfor-
mance will be somewhat different than under
normal driving conditions.● Always secure items in the trailer to prevent
load shift while driving.
● Lock the trailer hitch coupler with a pin or
lock to prevent the coupler from inadver-
tently becoming unlatched.
● Avoid abrupt starts, acceleration or stops.
● Avoid sharp turns or lane changes.
● Always drive your vehicle at a moderate
speed.
● When backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and
back up slowly. If possible, have someone
guide you when you are backing up.
Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so:
CAUTION
If you move the shift selector to the P
(Park) position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill side of the vehicle and trailer wheels.
3. After the wheel blocks are in place, slowly release the brake pedal until the blocks ab-
sorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park) .
6. Make sure the
indicator light (if so
equipped) indicates the transfer case is in
4H, 4L, or 2H and that the ATP light is off. If
the
indicator light is flashing, or the
ATP light is ON, make sure the transmission
is in P (Park) (A/T) and turn the 4WD switch
to 2WD or 4H. See “Automatic transmission
park warning light” in the “Instruments and
controls” section and “Using four wheel
drive (4WD)” in the “Starting and driving”
section.
7. Turn off the engine. To drive away:
1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks. ● While going downhill, the weight of the
trailer pushing on the tow vehicle may de-
crease overall stability. Therefore, to main-
tain adequate control, reduce your speed
and shift to a lower gear. Avoid long or
repeated use of the brakes when descend-
ing a hill, as this reduces their effectiveness
and could cause overheating. Shifting to a
lower gear instead provides “engine brak-
ing” and reduces the need to brake as fre-
quently.
● If the engine coolant temperature rises to a
high temperature, refer to “If your vehicle
overheats” in the “In case of emergency”
section of this owner’s manual.
● Trailer towing requires more fuel than normal
circumstances.
Technical and consumer information9-29

●Avoid towing a trailer for your vehicle’s first
500 miles (805 km) .
● For the first 500 miles (805 km) that you do
tow, do not drive over 50 MPH (80 km/h) .
● Have your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule in the “NISSAN Ser-
vice and Maintenance Guide”.
● When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this,
make a larger than normal turning radius
during the turn.
● Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling.
Do the following if the trailer begins to sway: 1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer as
straight ahead as the road conditions allow.
This combination will help stabilize the ve-
hicle
– Do not correct trailer sway by steering or applying the brakes. 2. When the trailer sway stops, gently apply the
brakes and pull to the side of the road in a
safe area.
3. Try to rearrange the trailer load so it is bal- anced as described earlier in this section.
● Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember, the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
● Use the Tow Mode or downshift the trans-
mission to a lower gear for engine braking
when driving down steep or long hills. This
will help slow the vehicle without applying
the brakes.
● Avoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
● Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
● NISSAN recommends that the cruise con-
trol not be used while towing a trailer. ●
Some states or provinces have specific
regulations and speed limits for vehicles that
are towing trailers. Obey the local speed
limits.
● Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.
● When launching a boat, don’t allow the wa-
ter level to go over the exhaust tail pipe or
rear bumper.
● Make sure you disconnect the trailer lights
before backing the trailer into the water or
the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more fre-
quently. For additional information, see the
“Maintenance and do-it-yourself” section
earlier in this manual.
Tow mode
Using tow mode is recommended when pulling a
heavy trailer or hauling a heavy load. Press the
TOW MODE switch to activate tow mode. The
indicator light on the TOW MODE switch illumi-
nates when tow mode is selected. Press the
TOW MODE switch again to turn tow mode off.
Tow mode is automatically cancelled when the
ignition switch is turned OFF.
