63J047
This selector is used to select the following
modes.
Fresh Air (f)
When this mode is selected, the indicator
light will go off and outside air is used.
Recirculated Air (g)
When this mode is selected, the indicator
light will come on, outside air is shut out
and inside air is recirculated. This mode is
suitable when driving through dusty or pol-
luted air such as in a tunnel, or when
attempting to quickly cool down the inte-
rior.
“FRESH AIR” and “RECIRCULATED AIR”
are switched alternately each time the air
intake selector is pushed.
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”.

System Operating InstructionsNatural ventilation
Select “VENTILATION” and “FRESH AIR”,
the temperature selector to the desired
temperature 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 posi-
tion, the air that comes out of the center
and side outlets will be cooler than the air
that comes out of the floor outlets.
Defrosting/Feet warmed heating
Select “HEAT & DEFROST” and “FRESH
AIR”, the temperature selector to the
desired temperature position, and the
blower speed selector to HIGH. When the
windshield has become clear, set the
blower speed selector to the desired
blower speed position.
Defrosting
Select “DEFROST” and “FRESH AIR”, the
temperature selector to the desired tem-
perature position (higher temperature pro-
vides more efficient defrosting), and the
blower speed selector to HIGH. When the
windshield has become clear, set the
blower speed selector to the desired
blower speed position.

NOTE:
If you need maximum defrosting, adjust the
temperature selector to the HOT end and
adjust the side outlets so the air blows on
the side window, in addition to the above
Defrosting steps.

Normal cooling
Turn on the “A/C” switch, set the air flow
selector to “VENTILATION”, the tempera-
ture selector to the desired temperature
position and the blower speed selector to
the desired blower speed position. 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:
 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 brieflywhile you operate the air conditioner with
the air intake selector at “FRESH AIR”
and the blower at high speed.
Dehumidifying
Turn on the “A/C” switch, set the air flow
selector to a desired air flow selector posi-
tion, and select “FRESH AIR”, the temper-
ature selector to the desired temperature
position, and the blower speed selector to
the desired blower speed position.
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.

NOTE:
If you need maximum defrosting:
 select “DEFROST” and “FRESH AIR”,
 turn on the “A/C” switch,
 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.
MaintenanceIf 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.
Your air conditioner is equipped with air fil-
ters. Clean or replace them as specified in
the “Maintenance Schedule” in the
“INSPECTION AND MAINTENANCE” sec-
tion. Have this job done by your SUZUKI
dealer as the lower glove box must be low-
ered for this job.
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.

CAUTION
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.

This is used to select the temperature by
turning the selector.
Also, this is used to turn on and off the air
conditioning system by pushing the switch.
To turn on the air conditioning system,
push in the switch and the A/C indicator
light (4) will come on. To turn off the air
conditioning system, push in the switch
again and the A/C indicator light (4) will go
off.
NOTE:
If the A/C indicator light (4) blinks, there is
a problem in the heating system and/or air
conditioning system. You should have the
system inspected by an authorized
SUZUKI dealer.Blower speed selector/Air intake selec-
tor (2)

This is used to turn on the blower and to
select blower speed.
If the selector is in “AUTO” position, the
blower speed will vary as the climate con-
trol system maintains the selected temper-
ature.
Also, this is used to select the following
modes by pushing the selector.

FRESH AIR
When this mode is selected, the indicator
light (a) will come on and outside air is
used.
RECIRCULATED AIR
When this mode is selected, the indicator
light (b) will come on, outside air is shut out
and inside air is recirculated. This mode is
suitable when driving through the polluted
air such as a tunnel, or attempting to
quickly cool down.
“FRESH AIR” and “RECIRCULATED AIR”
are switched alternately each time the air
intake selector is pushed.
