1997 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 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.

override the automatic dehumidifying
which occurs when
is selected.
Operating Tips
Clear snow and ice from the wiper
blades and air inlet in front of the wind-
shield. This improves defrosting/
defogging operation.
Bi-level heating/cooling
The bi-level mode directs air to the side and
center vents and to the 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 pushing the recirculation
button to the on position.
Push the air recirculation button to the off
position when heating is required.
1. Push the

performance.
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 ventilationmode, 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.

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 beoperated for about ten minutes at
least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
cIf the coolant temperature gauge ex-
ceeds 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, above the radio. The
EATC operates only when the ignition isturned 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 five function
selector buttons:
,,,
,or. 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 tem-
perature and AUTO show in the display
window. The EATC heats or cools to
achieve the set temperature.
When in AUTOMATIC and weather condi-
tions 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 gradually 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
selection. The
side lowers the set
temperature, and theside raises the
set temperature. Press and hold either side
of the button to rapidly change the tempera-
ture setting in one degree increments toeither 65ÉF (18ÉC) or 85ÉF (29ÉC). If you
want continuous maximum cooling, push
the
side of the TEMP button until
60ÉF (16ÉC) shows in the display window.
The EATC cools at maximum and disre-
gards the 60ÉF (16ÉC) setting until a warmer
temperature is selected. If you want con-
tinuous maximum heating, push the
side of the TEMP button until 90ÉF
(32ÉC) shows in the display window. The
EATC provides maximum heat regardless
of the 90ÉF (32ÉC) setting until a cooler
temperature is selected.
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 youto make special selections. The buttons are
grouped 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 floor and
windshield at the same time. Thein-
dicator light comes on, and the display
window shows the set temperature.
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
50ÉF (10ÉC) or above, the air is dehumidi-
fied 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 temperature.

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 operations'' section
of this manual.Freeing a frozen door lock
To prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole.
If the lock becomes frozen, heat the key
before inserting it into 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 operations'' section.
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
operations'' section.
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
operations'' section.
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
provinces and states prohibit their use.
Check local, state and provincial 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 if desired. Make
sure they are of proper size for the tires
on your vehicle and are installed accord-
