Fresh Air (f)
When this mode is selected by moving the
lever to right, outside air is used.
Recirculated Air (g)
When this mode is selected by moving the
lever to left, outside air is shut out and
inside air is recirculated. This mode is suit-
able when driving through dusty or polluted
air such as in a tunnel, or when attempting
to quickly cool down the interior.
NOTE:
If you select RECIRCULATED AIR for an
extended period of time, the air in the vehi-
cle can become contaminated. Therefore,
you should occasionally select FRESH
AIR.
Air conditioning switch (5) (if equipped)
To turn on the air conditioning system, set
the blower speed selector to a position
other than “OFF” and push in the “A/C”
switch. With this “A/C” switch operation, a
indicator light will come on when the air
conditioning system is on. To turn off the
air conditioning system, push “A/C” switch
again.
During operation of the air conditioner, you
may notice slight changes in engine
speed. These changes are normal, the
system is designed so that the compressor
turns on or off to maintain the desired tem-
perature.Less operation of the compressor results
in better fuel economy.
System Operating Instructions
Natural ventilation
Select VENTILATION and FRESH AIR, the
temperature selector to the desired tem-
perature position, and the blower speed
selector to off. Fresh air will flow through
the vehicle during driving.
Forced ventilation
The control settings are the same as for
natural ventilation except you set the
blower speed selector to a position other
than off.
Normal heating (using outside air)
Select HEAT and FRESH AIR, the tem-
perature selector to the desired tempera-
ture position and the blower speed selector
to the desired blower speed position. Set-
ting the blower speed selector to a higher
blower speed position increases heating
efficiency.
Quick heating (using recirculated air)
The control settings are the same as for
normal heating except you select RECIR-
CULATED AIR. If you use this heating
method for an extended period of time, the
air in the vehicle can become contami-
nated and the windows can become misty.
Therefore, use this method only for quick
heating and change to the normal heating
method as soon as possible.Head cooled/Feet warmed heating
Select BI-LEVEL and FRESH AIR, the
temperature selector to the desired tem-
perature position, and the blower speed
selector to the desired blower speed posi-
tion. Unless the temperature selector is in
the fully cold position or fully hot position,
the air that comes out of the center and
side outlets will be cooler than the air that
comes out of the floor outlets.
Normal cooling
Set the air flow selector to VENTILATION,
the temperature selector to the desired
temperature position and the blower speed
selector to the desired blower speed posi-
tion, and turn on the “A/C” switch. Setting
the blower speed selector to a higher
blower speed position increases cooling
efficiency.
You can switch the air intake selector to
either FRESH AIR or RECIRCULATED
AIR as you desire. Choosing RECIRCU-
LATED AIR increases cooling efficiency.
Quick cooling (using recirculated air)
The control settings are the same as for
normal cooling except you select RECIR-
CULATED AIR and the highest blower
speed.
NOTE:
• To turn on the air conditioning system,
push in the “A/C” switch and set the
blower speed selector to a position other
than OFF. With this “A/C” switch opera-

tion, an indicator light will come on when
the air conditioning system is on. To turn
off the air conditioning system, push the
“A/C” switch again.
• During operation of the air conditioner,
you may notice slight changes in engine
speed. These changes are normal, the
system is designed so that the compres-
sor turns on or off to maintain the
desired temperature. Less operation of
the compressor results in better fuel
economy.
NOTE:
• If you select RECIRCULATED AIR for an
extended period of time, the air in the
vehicle can become contaminated.
Therefore, you should occasionally
select FRESH AIR.
• If your vehicle has been left in the sun
with the windows closed, it will cool
faster if you open the windows briefly
while you operate the air conditioner with
the air intake selector at FRESH AIR and
the blower at high speed.
Dehumidifying
Set the air flow selector to a desired air
flow selector position, the temperature
selector to the desired temperature posi-
tion and the blower speed selector to the
desired blower speed position. Also select
FRESH AIR and turn on the “A/C” switch.NOTE:
Because the air conditioner dehumidifies
the air, turning it on will help keep the win-
dows clear, even when blowing heated air
using the DEFROST or HEAT &
DEFROST functions.
53MH0511
NOTE:
If you need maximum defrosting:
• set the air flow selector to DEFROST,
• set the blower speed selector to high,
• adjust the temperature selector to the
hot end, and
• adjust the side outlets so the air blows
on the side windows.
Maintenance
If you do not use the air conditioner for a
long period, such as during winter, it may
not give the best performance when you
start using it again. To help maintain opti-
mum performance and durability of your air
conditioner, it needs to be run periodically.
Operate the air conditioner at least once a
month for one minute with the engine
idling. This circulates the refrigerant and oil
and helps protect the internal components.
NOTE:
Your vehicle uses the air conditioning
refrigerant HFC-134a, commonly called
“R-134a”. R-134a replaced R-12 around
1993 for automotive applications. Other
refrigerants are available, including recy-
cled R-12, but only R-134a should be used
in your vehicle.
EXAMPLE
NOTICE
Using the wrong refrigerant may
damage your air conditioning sys-
tem. Use R-134a only. Do not mix or
replace the R-134a with other refrig-
erants.
