ENGINE COOLANT TEMPERATURE
GAUGE
NOTE:
The ignition key must be in the ON position
for the gauge to give a reading.
The gauge indicates the engine coolant tempera-
ture. The engine coolant temperature is within the
normal range when the reading is within the zone
s1shown in the illustration.
The engine coolant temperature varies with the
outside air temperature and driving conditions.
CAUTION
If the gauge indicates a coolant tempera-
ture near the hot (H) end of the normal
range, reduce vehicle speed to decrease
the temperature. If the gauge is over the
normal 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
ENGINE OIL PRESSURE GAUGE (if
so equipped)
The gauge indicates the engine lubrication sys-
tem oil pressure while the engine is running.
When the engine speed is high, the engine oil
pressure is also high. When the engine speed is
low, the gauge may indicate low oil pressure.
CAUTION
cThis gauge is not designed to indicate
low engine oil level. Use the dipstick to
check the oil level. (See “Engine oil” in
the “Maintenance and do-it-yourself”
section.)

4. Push thebutton. 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. Turn the air flow control dial to the
position.
2. Turn the fan control dial to the desired posi-
tion.
3. Push the
button. The indicator light
comes on.
When the
orposition is selected,
the air conditioner automatically turns on (how-
ever, the indicator light will not illuminate) . In this
position, the A/C cannot be turned off. When the
air flow control is turned to any position other
than
orthe A/C light will illuminate
(the A/C will continue operating) and can be
turned off using the A/C button. This dehumidi-
fies the air which helps defog the windshield. The
mode automatically turns off, allowing
outside air to be drawn into the passenger com-
partment to further improve the defogging perfor-
mance.4. Turn the temperature control dial to the de-
sired position.
Operating tips
cKeep the windows and sunroof closed while
the air conditioner is in operation.
cAfter 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.
cThe 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.
cA 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.
cIf 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.

tion for heating and defrosting.

ENGINE BLOCK HEATER (if so
equipped)
WARNING
cDo not use your engine block heater
with an ungrounded electrical system
or a 2-pronged adapter. You can be se-
riously injured by an electrical shock if
you use an ungrounded connection.
cDisconnect and properly store the en-
gine block heater cord before starting
the engine. Damage to the cord could
result in an electrical shock and can
cause serious injury.
cUse a heavy-duty 3-wire, 3-pronged ex-
tension cord rated for at least 10 A. Plug
the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the
proper extension cord or a grounded
outlet can result in a fire or electrical
shock and cause serious personal
injury.
Engine block heaters are available through
NISSAN dealers to assist in cold temperature
starting. The engine block heater should be used
when the outside temperature is 20° F (-7° C) or
lower.To use the engine block heater:
1. Turn the engine off.
2. Open the hood and unwrap the engine block
heater cord.
3. Plug the engine block heater cord into a
grounded 3 wire, 3 pronged extension cord.
4. Plug the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded 110-
volt AC (VAC) outlet.
5. The engine block heater must be plugged in
for at least2-4hours, depending on outside
temperatures, to properly warm the engine
coolant. Use an appropriate timer to turn the
engine block heater on.
6. Before starting the engine, unplug and prop-
erly store the cord to keep it away from
moving parts.

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 when the coolant
temperature is high.6. After the engine cools down, check the cool-
ant level in the engine coolant reservoir tank
with the engine running. Add coolant to the
engine coolant reservoir tank if necessary.

dealer.When towing your vehicle, all State (Provincial in
Canada) and local regulations for towing must be
followed. Incorrect towing equipment could dam-
age your vehicle. Towing instructions are avail-
able from a NISSAN dealer. Local service opera-
tors are generally familiar with the applicable laws
and procedures for towing. To assure proper
towing and to prevent accidental damage to your
vehicle, NISSAN recommends having a service
operator tow your vehicle. It is advisable to have
the service operator carefully read the following
precautions:
WARNING
cNever ride in a vehicle that is being
towed.
cNever get under your vehicle after it has
been lifted by a tow truck.
CAUTION

bing for cuts, fraying, wear or damage.
Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimesMake sure all
warning lights and chimes are operating properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Brake and clutch fluid levels*Make sure that
the brake and clutch fluid level is between the
MIN and MAX lines on the reservoir.Engine coolant level*Check the coolant level
when the engine is cold.
Engine drive belts*Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level*Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
Exhaust systemMake sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by a NISSAN dealer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.
Fluid leaksCheck under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield washer fluid*Check that there is
adequate fluid in the reservoir.
