engine overheat NISSAN XTERRA 2014 N50 / 2.G Owners Manual

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 vehicle
may seriously damage the engine. See “If
your vehicle overheats” in the “In case of
emergency” section for immediate action
required.
FUEL GAUGE
The gauge indicates theapproximatefuel level
in the tank.
The gauge may move slightly during braking,
turning, acceleration, or going up or down hills.
The gauge needle returns to E (Empty) after the
ignition key is turned to OFF.
The low fuel warning light comes on when the
amount of fuel in the tank is getting low.
Refill the fuel tank before the gauge regis-
ters E (Empty) . The
indicates that the fuel-filler door is
located on the driver’s side of the vehicle.
CAUTION
● If the vehicle runs out of fuel, theMalfunction Indicator Light (MIL) may
come on. Refuel as soon as possible.
After a few driving trips. the
light
should turn off. If the light remains on
after a few driving trips, have the vehicle
inspected by a NISSAN dealer.
● For additional information, see “Mal-
function Indicator Light (MIL)” later in
this section.

the outside temperature is more than 36°F (2°C) .
If one of these air flow control buttons is selected
for more than one minute, the air conditioning
system will continue to operate until the fan con-
trol dial is turned to OFF, the air conditioner is
turned OFF, or the vehicle is shut off, even if a
position other than these positions is selected.
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
●Keep the windows closed while the air con-
ditioner is in operation.
● After parking in the sun, drive for 2 or 3 min-
utes 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. For additional information
on heating and cooling, see “Heater and air con-
ditioner (manual)” in this section. The air recir-
culation (
) button should always be in
the OFF position for heating and defrost-
ing.

●Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
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

●Many 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.
● Do not shift gears while driving on
downhill grades as this could cause
loss of control of the vehicle.
● Stay 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.
● If 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 ve-
hicles) , using only the brake, as this
could cause loss of control.
● Heavy 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. Use the hill
descent control feature (if so
equipped) . ●
Unsecured cargo can be thrown around
when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
● To avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack/gear bin (if so
equipped) and evenly distribute the
load. Secure heavy loads in the cargo
area as far forward and as low as pos-
sible. Do not equip the vehicle with tires
larger than specified in this manual.
This could cause your vehicle to roll
over.
● Do not grip the inside or spokes of the
steering wheel when driving off-road.
The steering wheel could move sud-
denly and injure your hands. Instead
drive with your fingers and thumbs on
the outside of the rim.
● Before operating the vehicle, ensure
that the driver and all passengers have
their seat belts fastened.
● Always drive with the floor mats in place
as the floor may become hot. ●
Lower your speed when encountering
strong crosswinds. With a higher center
of gravity, your NISSAN is more affected
by strong side winds. Slower speeds
ensure better vehicle control.
● Do not drive beyond the performance
capability of the tires, even with 4WD
engaged.
● For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
5-8Starting and driving

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.
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.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
Parking brake break-in
Break-in the parking brake shoes whenever the
effect of the parking brake is weakened or when-
ever the parking brake shoes and/or drum/rotors
are replaced, in order to assure the best brake
performance.
POWER STEERING BRAKE SYSTEM
5-32Starting and driving

CAUTION
●Do not push start this vehicle. The
three-way catalyst may be damaged.
● Automatic transmission models cannot
be push-started or tow-started. At-
tempting to do so may cause transmis-
sion damage.
● For manual transmission 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.
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.
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. 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. 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
In case of emergency6-11

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 dam-
age 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 protection
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 re-
duce 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.
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.
