Instruments and controls2-3

The low tire pressure warning light remains
illuminated until the tires are inflated to the
recommended COLD tire pressure. The
CHECK TIRE PRES (pressure) warning mes-
sage is displayed each time the ignition
switch is placed in the ON position as long
as the low tire pressure warning light re-
mains illuminated.
For additional information, refer to “Low tire
pressure warning light” in this section, “Tire
Pressure Monitoring System (TPMS)” in the
“Starting and driving” section, and “Wheels
and tires” in the “Do-it-yourself ” section of
this manual.
TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (rpm).
Do not rev the engine into the red zone
1.
CAUTION
When engine speed approaches the red
zone, shif t to a higher gear or reduce
engine speed. Operating the engine in
the red zone may cause serious engine
damage.
ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant
temperature. The engine coolant tempera-
ture is within the normal range
1when
the gauge needle points within the zone
shown in the illustration.
The engine coolant temperature varies
with the outside air temperature and driv-
ing conditions.
LIC0738LIC0739
2-6Instruments and controls

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
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.
For additional information, refer to “If
your vehicle overheats” in the “In case
of emergency ” section of this manual
for immediate action required.
FUEL GAUGE
The gauge indicates theapproximatefuel
level in the tank.
The gauge may move slightly during brak-
ing, turning, acceleration, or going up or
down hills.
The gauge needle returns to 0 (Empty) af-
ter the ignition switch is placed in the OFF
position.
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 reg-
isters 0 (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.
Af ter a few driving trips, the
light
should turn off. If the light remains on
af ter a few driving trips, have the ve-
hicle inspected. It is recommended
that you visit a NISSAN dealer for this
service.
∙ For additional information, refer to “Malfunction Indicator Light (MIL)” in
this section.
DISTANCE TO EMPTY (DTE)
Displays the estimated distance the ve-
hicle can be driven before refueling. The
value is calculated based on recent fuel
economy, the amount of fuel remaining in
the fuel tank, and the actual fuel consump-
tion.
Changes in driving patterns or conditions
can cause the DTE value to vary. As a result,
the value displayed may differ from the ac-
tual distance that can be driven.

∙ For quick cooling when the outsidetemperature is high, press the
button to the ON position. Be sure to
return the
to the OFF position for
normal cooling. The indicator light on
the
button will go off. You may
also select MAX A/C for quick cooling.
Dehumidified heating
This mode is used to heat and dehumidif y
the air.
1. Press the
air flow control button.
2. Turn the
fan speed control dial to
the desired position.
3. Press the
button on.
4. Turn the temperature control dial to the desired position.
Dehumidified defogging
This mode is used to defog the windows
and dehumidif y the air.
1. Press the
air flow control button.
2. Turn the
fan speed control dial to
the desired position. ∙ When the
orare selected,
the air conditioner automatically turns
on if the outside temperature is more
than 36° F (2° C). 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 im-
prove the defogging performance.
∙ The air conditioner is always on in the
mode, regardless of whether
the indicator light is on or off.
3. Turn the temperature control dial to the desired position.
Operating tips
∙ Keep the windows and moonroof (if soequipped) closed while the air condi-
tioner is in operation.
∙ Af ter parking in the sun, drive for two or three minutes with the windows open
to vent hot air from the passenger
compartment. Then, close the win-
dows. This allows the air conditioner to
cool the interior more quickly. ∙
The air conditioning system should
be operated for approximately
10 minutes at least once a month.
This helps prevent 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. For additional
information, refer to “If your vehicle
overheats” in the “In case of emer-
gency ” section of this manual.AIR FLOW CHARTS
The following charts show the button and
dial positions for MAXIMUM AND QUICK
heating, cooling or defrosting. The air re-
circulation (
) button should always
be in the OFF position for heating and
defrosting.

OPERATING TIPS
The sunload sensor1, located on the top
center of the instrument panel, helps the
system maintain a constant temperature.
Do not put anything on or around this sen-
sor.
∙ When the engine coolant temperature and outside air temperature are low, the
air flow from the foot outlets may not
operate for a maximum of 150 seconds.
However, this is not a malfunction. Af ter
the coolant temperature warms up, air
flow from the foot outlets will operate
normally. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth’s ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, refer to “Air conditioner sys-
tem refrigerant and oil recommendations”
in the “Technical and consumer informa-
tion” section of this manual.
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly” air conditioning system.
WARNING
The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper
equipment.
RADIO
With the ignition placed in the ACC or ON
position, press the PUSH
(power) or
ON•OFF button to turn the radio on. If you
listen to the radio with the engine not run-
ning, the ignition should be placed in the
ACC position.
Radio reception is affected by station sig-
nal strength, distance from radio transmit-
ter, buildings, bridges, mountains and other
external influences. Intermittent changes
in reception quality normally are caused by
these external influences.
Using a cellular phone in or near the ve-
hicle may influence radio reception qual-
ity.
Radio reception
Your NISSAN radio system is equipped with
state-of-the-art electronic circuits to en-
hance radio reception. These circuits are
designed to extend reception range, and to
enhance the quality of that reception.
However, there are some general charac-
teristics of both FM and AM radio signals
that can affect radio reception quality in a
moving vehicle, even when the finest
equipment is used. These characteristics
are completely normal in a given reception
