1999 NISSAN QUEST Owners Manual

NOTE: When switching air flow outlets, the
A/C system remains activated unless the
A/C button is pressed to the OFF position.
The indicator light on the A/C button re-
mains illuminated unless the button is
pressed to the OFF position, or the OFF air
control position is selected.
Cooling
This mode is used to cool and dehumidify.
1. Move the air control dial to the
po-
sition.
2. Turn the fan control dial to select speed.
3. Push the air conditioner button. The indi-
cator light comes on.
4. Move the temperature control dial to the
desired position.
cFor quick cooling when the outside tem-
perature is high, move the air control dial
to the MAX A/C position. Be sure to
return the air control dial to the
po-
sition for normal cooling.
cOpening the windows helps to vent heat
buildup when parked in the sun.
Dehumidified heating
This mode is used to heat and dehumidify.
1. Move the air control dial to the
po-
sition.
2. Turn the fan control dial to select speed.
3. Push the air conditioner button. The indi-
cator light comes on.
4. Move the temperature control dial to the
desired position.
Dehumidified defogging
This mode is used to defog the windows
and dehumidify.
1. Move the air control dial to the
po-
sition.
2. Turn the fan control dial to the desired
speed.
3. Move the temperature control dial to the
desired position.
When the
position is selected, the
air conditioner automatically turns on
(however, the indicator light will not illu-
minate) if the outside temperature is
more than 45ÉF (7ÉC). This dehumidifies
the air which helps defog the windshield.The air recirculation mode automatically
turns off, allowing outside air to be drawn
into the passenger compartment which
helps defog the windshield.
Operating tips
cKeep windows and sun roof closed while
the air conditioner is in operation.
cAfter parking in the sun, drive for two or
three minutes with the windows open to
vent hot air from the passenger compart-
ment. Then, close the windows. This
allows the air conditioner to cool the
interior more quickly.
cThe air conditioning system should be
operated for about ten minutes at
least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
cIf the engine coolant temperature gauge
exceeds the H (hot) position, turn the air
conditioner off. See ``If your vehicle over-
heats'' in the ``In case of emergency''
section for additional information.

WARNING
cThe air conditioner cooling function
operates only when the engine is
running.
cDo not leave children, unreliable
adults, or pets alone in your vehicle.
On hot, sunny days, temperatures in
a closed vehicle could quickly be-
come high enough to cause severe
or possibly fatal injuries to people or
animals.
cDo not use the MAX mode for long
periods as it may cause the interiorair to become stale and the windows
to fog up.
cPositioning of the heater and air con-
ditioner controls should not be done
while driving, in order that full atten-
tion may be given to the driving
operation.
The cabin air filter (if so equipped) requires
periodic maintenance. See the ``Do it your-
self'' section for additional information.
The Electronic Automatic Temperature
Control (EATC) is located at the center of
the instrument panel, below the radio. TheEATC operates only when the ignition is
turned to the ON position.
The EATC maintains the temperature you
select and controls the airflow for your com-
fort. It also allows you to override the auto-
matic operation with manual function selec-
tor buttons.
To turn the EATC on, push either the AU-
TOMATIC button or any of the six function
selector buttons:
,,,,or MAX. To turn the EATC off, press
the OFF button.
When you select AUTOMATIC, the system
determines fan speed, airflow location and
discharge air temperature. When one of the
function selector buttons is pressed, your
selection determines airflow location only.
Fan speed and discharge air temperature
remain automatic. You can override fan
speed by rotating the vertical thumbwheel
located at the extreme right of the
control panel.
The display window indicates the status of
the system. It shows the selected tempera-
ture and AUTO when in the AUTOMATIC
mode. It also indicates manual (thumb-
wheel) control of the fan speed when a
is shown.

AUTOMATIC OPERATION
Push the AUTOMATIC button and select the
desired temperature. The selected tempera-
ture and AUTO show in the display window.
The EATC heats or cools to achieve the set
temperature.
When in AUTOMATIC and weather conditions
require heat, air is sent to the floor. However,
a feature is included in the EATC to prevent
blowing cold air to the floor if the engine
coolant is not warm enough to allow heating.
In three or four minutes the fan speed gradu-
ally increases and airflow changes to the floor.
If unique conditions exist, such as window
fogging, the five override buttons allow spe-
cific airflow selection. The thumbwheel al-
lows you to adjust the fan speed to suit your
needs.
Temperature selection
TheTEMPbutton on the left side of
the control panel is for temperature selec-
tion. The
side lowers the set tempera-
ture, and theside raises the set tem-
perature. Press and hold either side of the
button to rapidly change the temperature
setting in one degree increments to either
65ÉF (18ÉC) or 85ÉF (29ÉC). If you wantcontinuous maximum cooling, push the
side of the TEMP button until 60ÉF
(16ÉC) shows in the display window. The
EATC cools at maximum and disregards the
60ÉF (16ÉC) setting until a warmer tempera-
ture is selected. If you want continuous
maximum heating, push the
side of the
TEMP button until 90ÉF (32ÉC) shows in the
display window. The EATC provides maxi-
mum heat regardless of the 90ÉF (32ÉC)
setting until a cooler temperature is se-
lected.
Fan speed and thumbwheel
Your EATC automatically adjusts the fan
speed to the existing conditions. To control
the fan speed yourself, use the thumbwheel
located at the extreme right side of the
EATC control panel. Using the thumbwheel
cancels the automatic fan speed control,
and causes a
to appear in the display
window. Rotate the thumbwheel up for HI
speeds and down for LO speeds.
To return to auto fan control, press the
AUTOMATIC button.
AIR CONTROL BUTTONS
Your EATC has five buttons which allow you
to make special selections. The buttons aregrouped in the middle of the EATC panel
and allow you to determine airflow location.
Pressing any of the air control buttons
changes airflow location only, and does not
affect the ability of the system to control
temperature or fan speed. Return to fully
automatic operation by pushing the AUTO-
MATIC button.
Push this button for airflow to the front and
rear floor outlets and windshield at the same
time. The
indicator light comes on,
and the display window shows the set tem-
perature.
Press this button to obtain maximum airflow
to the windshield. Adjust the temperature
setting as required for defrosting. The
indicator light comes on, and the
display window shows the set temperature.
When the outside temperature is about
45ÉF (7ÉC) or above, the air is dehumidified
to prevent window fogging.
Push this button to select airflow through

the instrument panel registers. The
indicator light comes on, and the
display window shows the set tem-
perature. The EATC heats the air if the
selected temperature is warmer than the
outside air coming into the vehicle. How-
ever, the air is not cooled regardless of the
temperature setting, unless the A/C button
is selected.
Push this button to get air from the front and
rear floor outlets and instrument panel ven-
tilators at the same time. The
indicator
light comes on and the display window
shows the set temperature. The EATC
heats the air if the selected temperature is
warmer than the outside air coming into the
vehicle. However, the air is not cooled re-
gardless of the temperature setting, unless
the A/C button is selected.
Push this button to direct airflow to the front
and rear floor outlets. Theindicator
light comes on, and the display window
shows the set temperature. The EATC
heats the air if the selected temperature is
warmer than the outside air coming into thevehicle. However, the air is not cooled re-
gardless of the temperature setting, unless
the A/C button is selected.
Press the MAX button to choose air recircu-
lation. In this mode the EATC system recir-
culates the air inside the vehicle rather than
drawing air from outside. Air is distributed
through the instrument panel ventilators
similar to
mode. Use this mode to rap-
idly cool the inside of the vehicle, or to
dehumidify the air inside the vehicle.
Activate the air conditioner in any of the
override modes listed above by pressing the
A/C button. The A/C indicator light comes
on to verify activation, and cooled air flows
from the vents. Fan speed continues to be
controlled by the EATC unless the fan
speed thumbwheel is used to override.ENGLISH/METRIC MODE
Switch from English to metric temperature
display by simultaneously pressing the
and A/C buttons and holding the
thumbwheel in upper position (HI) for one
second.
