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.

you should occasionally select “FRESH
AIR”.Air conditioning switch (5)
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 operation, a
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 compressor
turns on or off to maintain the desired tem-
perature.
Less operation of the compressor results
in better fuel economy.

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.

conditioning system. You should have the
system inspected by an authorized
SUZUKI dealer.Blower speed selector/Air intake selec-
tor (2)
79J096
This is used to turn on the blower and to
