1999 NISSAN QUEST cooling

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 (recirculation)
mode for long periods as it may
cause the interior air 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.

OFF position
The OFF position shuts off the air supply to
all outlets and stops all fan operations. Use
the OFF position to prevent cold air from
entering the passenger compartment under
cold outside conditions before the engine is
warmed up.
MAX A/C Position
Interior air is recirculated inside the vehicle.
Turn the air control dial to the MAX A/C
position when driving on a dusty road or
to help keep out traffic fumes.
Turn the air control dial to the MAX A/C
position for improved air conditioner perfor-
mance under high temperature and high hu-
midity conditions.
CAUTION
Do not use MAX A/C for long periods as
it may cause the interior air to become
stale and the windows to fog up.
Air conditioner button
Start the engine, move the fan control dial to
the desired (one to four) position, select an
air control position and push the air condi-tioner button to turn on the air conditioner.
The indicator light comes on when the air
conditioner is operating. To stop the air con-
ditioner, push the button again; the indicator
light goes off.
The air conditioner cooling function op-
erates only when the engine is running.
HEATER OPERATION
Heating
This mode is used to direct most of the hot
air to the front and rear floor outlets. Rear
passenger heat is provided by the front
system through floor outlets located under
both front seats.
1. Move the air control dial to the
po-
sition.
2. Turn the fan control dial to select speed.
3. Move the temperature control dial to the
desired position.
Ventilation
This mode directs air to the side and center
vents.

Operating Tips
Clear snow and ice from the wiper blades
and air inlet in front of the windshield.
This improves defrosting/defogging op-
eration.
Bi-level heating/cooling
The bi-level mode directs air to the side and
center vents and to the front and rear floor
outlets.
Bi-level is also a cooling mode when high
sun load conditions are present with cool
temperatures.
With the A/C system in operation, this mode
can be used to cool the passenger's or
driver's feet under high temperature condi-
tions.
With the A/C system in operation under high
temperature conditions, improved cooling
can be obtained by moving the air control
dial to the MAX A/C position.
1. Move the air control dial to the
po-
sition.
2. Turn the fan control dial to the desired
position.3. Move the temperature control dial to the
desired position.
Heating and defogging
This mode heats the interior and defogs the
windshield. This mode directs air to the
defroster and the front and rear floor outlets.
Rear passenger heat is provided by the
front system through floor outlets located
under both front seats.
1. Move the air control dial to the
po-
sition.
2. Turn the fan control dial to the desired
position.
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
cClear snow and ice from the wiper
blades and air inlet in front of the
windshield. This improves heater op-
eration.
cTo defog the side windows more effec-
tively when in bi-level or ventilation
mode, close the center vent and direct
the side vents toward the side windows.
cA slight delay may be experienced when
changing air control buttons. This is not a
problem, it is only the system motors and
solenoids switching from one outlet to
another.

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.

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.

cWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. For tire
placard location information, refer to
``Tire placard'' in the Owner's
Manual index.
cRefer to ``Wheels and tires'' in the
``Do-it-yourself'' section of this
manual.Freeing a frozen door lock
To prevent a door lock from freezing, apply
de-icer or glycerin through the key hole. If
the lock becomes frozen, heat the key be-
fore inserting it in the key hole.
Anti-freeze
In the winter, when it is anticipated that the
temperature will drop below 32ÉF (0ÉC),
check the anti-freeze (ethylene glycol base)
to assure proper winter protection. For de-
tails, see ``Engine cooling system'' in the
``Do-it-yourself'' section of this manual.
Battery
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For
details, see ``Battery'' in the ``Do-it-yourself''
section of this manual.
Draining of coolant water
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by
opening the drain valves located under the
radiator and on the engine block. Refillbefore operating the vehicle. See ``Chang-
ing engine coolant'' in the ``Do-it-yourself''
section of this manual.
Tire equipment
1. SUMMER tires are of a tread design to
provide superior performance on dry
pavement. However, the performance of
these tires is substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads, NIS-
SAN recommends using MUD & SNOW
or ALL SEASON tires on all four wheels.
Please consult your NISSAN dealer for
the tire type, size, speed rating and avail-
ability information.
2.
For additional traction on icy roads, stud-
ded tires may be used. However, some
Canadian provinces and U.S. states pro-
hibit their use. Check local, state and pro-
vincial laws before installing studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may
be poorer than that of non-studded snow
tires.
3. Tire chains may be used. Make sure they
are of proper size for the tires on your
vehicle and are installed according to the
