2003 NISSAN MURANO engine overheat

ENGINE COOLANT TEMPERATURE
GAUGEThe gauge indicates the engine coolant tem-
perature.
The engine coolant temperature will vary with the
outside air temperature and driving conditions.
CAUTION
If the gauge indicates engine coolant
temperature over the normal range,
stop the vehicle as soon as safely pos-
sible. If the engine is overheated, con-
tinued operation of the vehicle may se-
riously damage the engine. See “If your
vehicle overheats” in the “6. In case of
emergency” section for immediate ac-
tion 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 key is turned
to the OFF position.
Refill the fuel tank before the gauge regis-
ters Empty.

headlights or rear window defroster
is on.

Before inserting or disconnecting a
plug, be sure to turn off the power
switch of electrical accessory being
used or the ACC power of the vehicle.

Push the plug in as far as it will go. If
good contact is not made, the plug
may overheat or the internal tem-
perature fuse may blow.

When not in use, be sure to replace
the cover. Do not allow water to con-
tact the socket.

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 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
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.
LOW TIRE PRESSURE WARNING
SYSTEM (if so equipped)This vehicle is equipped with the low tire pres-
sure warning system, which displays pressure of
all tires (except the spare tire) on the display
screen by sending a signal from a sensor that is
installed in each wheel.
The low tire pressure warning system will acti-
vate only when the vehicle is driven at speeds
above 20 MPH (32 km/h). Also, this system may
not detect a sudden drop in tire pressure (for
example, a flat tire while driving).
Frequently check the tire pressure information
display on the display screen and adjust pres-
sure of each tire properly. (The order of the tire
pressure figures displayed on the screen does
not correspond with the actual order of the tire
position.) See “Tire pressure information” in the
“4. Display screen, heater, air conditioner and
audio systems” section for tire pressure monitor.LOW TIRE PRESSURE warningIf the vehicle is being driven with a low tire
pressure (lower than 27 psi, 190 kPa), the low
tire pressure warning light comes on, and the
chime sounds for about 10 seconds.

backward.

Many hills are too steep for any ve-
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 selector lever while driv-
ing 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 ofthe 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
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

Turn the wheels toward the side of the road
so the vehicle will move away from the center
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 drive belt breaks, you will
still have control of the vehicle. However, much
greater steering effort is needed, especially in
sharp turns or 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.
BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Vacuum assisted brake
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 the stopping
distance will be longer.
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 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.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This overheats 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 power
assist 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 at
speeds 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 pulsation mayindicate 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 mal-
function, it switches the anti-lock brake system
OFF and turns on the ABS warning light in the
meter. The brake system will then behave nor-
mally, but without anti-lock assistance.
If the light comes on during the self check, or
while you are driving, you should take your
vehicle to your NISSAN dealer for repair at your
earliest convenience.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-

7. After starting your 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.Do not start the engine by pushing.
CAUTION

CVT models cannot be push started.
This may cause transmission dam-
age.

Three way catalyst equipped models
should not be started by pushing
since the three way catalyst may be
damaged.

Never try to start the vehicle by tow-
ing it; when the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle.
WARNING

Do not continue to drive if your ve-
hicle overheats. Doing so could
cause 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

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze cool-
ant solution. The anti-freeze solution contains
rust and corrosion inhibitors, therefore additional
cooling system additives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only a genuine NISSAN
anti-freeze coolant or equivalent with
the proper mixture ratio of 50% anti-
freeze and 50% demineralized
water/distilled water. The use of other
types of coolant solutions may damage
your engine cooling system.Outside temperature

WARNING

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

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

The radiator is equipped with a pres-
sure cap. To prevent engine damage,
use only a genuine NISSAN radiator
cap.
CHECKING ENGINE COOLANT
LEVELCheck the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below MIN, add coolant up to the MAX level. If
the reservoir tank is empty, add the coolant to
the reservoir tank up to the MAX level.
If the engine cooling system frequently
requires coolant, have it checked by your
NISSAN dealer.
