2006 NISSAN MURANO engine overheat

ENGINE COOLANT TEMPERATURE
GAUGEThe gauge indicates the engine coolant tem-
perature.
The engine coolant temperature is within the
normal range
A
when the gauge needle points
within the zone shown in the illustration.
The engine coolant temperature will vary with the
outside air temperature and driving conditions.
CAUTION
If the gauge indicates engine coolant
temperature near the hot (H) end of the
normal range, reduce vehicle speed to
decrease temperature. If the gauge is
over the normal range, stop the vehicle
as soon as safely possible. If the engine
is overheated, 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 GAUGEThe gauge indicates the approximate fuel level in
the tank.
The gauge may move slightly during braking,
turning, acceleration, or going up or down hill.
The gauge needle is designed to move to the E
(Empty) position when the ignition switch is
turned to the OFF position.
Refill the fuel tank before the gauge regis-
ters Empty.

d. You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.
THREE-WAY CATALYSTThe three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the converter are burned at high tem-
peratures to help reduce pollutants.
WARNING

The exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust system compo-
nents.

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
reduce the three-way catalyst’s abil-
ity 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
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly by a NISSAN
dealer.

Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.

Do not race the engine while warm-
ing it up.

Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS) (if so equipped)Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle plac-
ard 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 infla-
tion pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a tire pressure
telltale when one or more of your tires is signifi-
cantly 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
significantly under-inflated tire causes the tire to
overheat 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

hicle. 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 ranges while driving on
downhill grades as this could cause
loss of control of the vehicle.

Be sure to use the engine brake. The
foot brake performance may be re-
duced, resulting in a possible acci-
dent.

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 attempt to turn around. Your
vehicle could tip or roll over. Always
back straight down in R (Reverse)
range. Never back down in N (Neu-
tral), 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 accident. Apply brakes lightly
and use a low range to control your
speed.

Unsecured cargo can be thrown
around when driving over rough ter-
rain. Properly 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 (if so
equipped) and evenly distribute the
load. Secure heavy loads in the cargo
area as far forward and as low as
possible. Do not equip the vehicle
with tires larger than specified in this
manual. This could cause your ve-
hicle to roll over.

Do not grip the inside or spokes of
the steering wheel when driving off-
road. The steering wheel could move
suddenly and injure your hands. In-stead 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 AWD
engaged.
Accelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.

If at all possible, avoid sharp turning
maneuvers, particularly at high
speeds. Your NISSAN all-wheel drive
vehicle has a higher center of gravity
than a two-wheel drive vehicle. The

best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by a NISSAN
dealer.Using the brakesAvoid resting your foot on the brake pedal while
driving. This will cause overheating of the brakes,
increases wear on the brake linings and pads,
and reduces gas mileage.
To help save the brakes 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, accelerat-
ing or downshifting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an acci-
dent.

If the engine is not running or is
turned off while driving, the powerassist for the brakes will not work.
Braking will be harder.
ANTI-LOCK BRAKE SYSTEM (ABS)The anti-lock brake system controls the brakes
at each wheel so the wheels will not lock when
braking abruptly or when braking on slippery
surfaces. The system detects the rotation speed
at each wheel and varies the brake fluid pressure
to prevent each wheel from locking and sliding.
By preventing wheel lockup, the system helps
the driver maintain steering control and helps to
minimize swerving and spinning on slippery sur-
faces.Using the systemDepress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.Normal operationThe anti-lock brake system will not operate atspeeds below 3 to 6 MPH (5 to 10 km/h) to
completely stop the vehicle. (The speeds will
vary according to road conditions.) When the
anti-lock system senses that one or more wheels
are close to locking up, the actuator (under the
hood) rapidly applies and releases hydraulic
pressure (like pumping the brakes very quickly).
While the actuator is working, you may feel a
pulsation in the brake pedal and hear a noise or
vibration from the actuator under the hood. This
is normal and indicates that the anti-lock system
is working properly. However, the ABS operation
may indicate that road conditions are hazardous
and extra care is required while driving.
Self-test featureThe anti-lock brake system consists of electronic
sensors, electric pumps and hydraulic solenoids
controlled by a computer. The computer has a
built-in diagnostic feature that tests the system
each time you start the engine and move the
vehicle at a low speed in forward or reverse.
When the self-test occurs, you may hear a
“clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indication of
any malfunction. If the computer senses any
malfunction, it switches the anti-lock brake sys-
tem off and turns on the ABS warning light on
the instrument panel. The brake system then
operates normally, but without anti-lock assis-
tance.

WARNING

Do not continue to drive if your ve-
hicle 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 ra-
diator cap is removed, pressurized
hot water will spurt out, possibly
causing serious injury.

Do not open the hood if steam is
coming 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 selector lever to
the P (Park) position.
Do not stop the engine.
2. Turn off the air conditioner switch. Open all
the windows, move the heater or air condi-tioner 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 rpm) until the tem-
perature gauge indication returns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or coolant
is escaping, turn off the engine.) 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
engine, stand clear to prevent getting
burned.
6. Visually check if the cooling fan is running.
The radiator hoses and radiator should not
leak water.
If coolant is leaking or the cooling fan does
not run, stop the engine.
WARNING

Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or get caught in, drive
belt, or cooling fan.

The engine cooling fan can start at
any time when the coolant tempera-
ture is high.
7. 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 the
nearest NISSAN dealer.

The engine cooling system is filled at the factory
with a high-quality, year-round, antifreeze cool-
ant solution. The antifreeze solution contains rust
and corrosion inhibitors, therefore additional
cooling system additives are not necessary.
WARNING

Never remove the radiator cap when
the engine is hot. Wait until the en-
gine and radiator cool down. Serious
burns could be caused by high pres-
sure fluid escaping from the radiator.
Wait until the engine and radiator
cool down.

See “If your vehicle overheats” in the
“In case of emergency” section of
this manual.

The radiator is equipped with a pres-
sure type radiator cap. To prevent
engine damage, use only a genuine
NISSAN radiator cap.
CAUTION
When adding or replacing coolant, be
sure to use only a Genuine NISSAN
Long Life Antifreeze/Coolant (green) or
equivalent with the proper mixture ratio
of 50% anti-freeze and 50% demineral-
ized or distilled water. The use of other
types of engine coolant may damage

CHANGING ENGINE COOLANTContact a NISSAN dealer if replacement is
required.

Major cooling system repairs should be per-
formed by a NISSAN dealer. The service
procedures can be found in the appropriate
NISSAN Service Manual.

Improper servicing can result in reduced
heater performance and engine overheating.
WARNING

To avoid being scalded, never change
the coolant when the engine 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 reach of children
and pets.
CHECKING ENGINE OIL LEVEL1. Park the vehicle on a level surface and apply
parking brake.
2. Run the engine 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 as illustrated and wipe it
clean. Reinsert it all the way.5. Remove the dipstick again and check the oil
level. It should be between the H and L marks
1. If the oil level is below the L mark
2,
remove the oil filler cap and pour recom-
mended oil through the opening.Do not

6. Recheck oil level with dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the severity
of operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the
engine, and such damage is not covered
by warranty.

engine stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels, imme-
diately change to a non-oxygenate fuel or a fuel
with a low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.E-85 fuelE-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 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispensing
pumps to be identified by a small, square, or-
ange and black label with the common abbre-
viation or the appropriate percentage for that
region.Aftermarket fuel additivesNISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel in-
jector cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for gum,
varnish or deposit removal may contain active
solvent or similar ingredients that can be harmful
to the fuel system and engine.
Octane rating tipsUsing 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 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 your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer or other competent service fa-
cility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
