Evacuation
CAUTION!
Do not evacuate before recovering
refrigerant in A/C system.

NOTE
Once air conditioning system circuit is
opened (exposed) to atmospheric air, system
must be evacuated by using a vacuum pump.
The A/C system should be attached with a
manifold gauge set, and should be evacuated
for approximately 15 minutes.

1) Connect high charging hose (1) and low charging hose (2) of manifold gauge set (3) respectively as
follows:
High charging hose → High pressure charging valve
(4) on condenser outlet pipe
Low charging hose → Low pressure charging valve
(5) on suction pipe
2) Attach center charging hose (6) of manifold gauge set to vacuum pump (7).
3) Operate vacuum pump, and then open discharge
side valve (Hi) (8) of manifold gauge set.
If there is no blockage in the system, there will be an
indication on high pressure gauge (9).
In this case, open the other side valve (Lo) (10) of
the set and repair the system.
4) Approximately 10 minutes later, low pressure gauge (11) should show a vacuum lower than –100 kPa (–
1.0 kg/cm
2, –760 mmHg, –14.7 psi) providing no
leakage exists.
NOTE
• If the system does not show a vacuum below –100 kPa (–1.0 kg/cm
2, –760 mmHg,
–14.7 psi), close both valves, stop vacuum
pump and watch movement of low
pressure gauge.
• Increase in the gauge reading suggests existence of leakage. In this case, repair
the system before continuing its
evacuation.
• If the gauge shows a stable reading (suggesting no leakage), continue
evacuation.

5) Evacuation should be carried out for a total of at least 15 minutes.
6) Continue evacuation until low pressure gauge indicates a vacuum less than –100 kPa (–1.0 kg/cm
2,
–760 mmHg, –14.7 psi), and then close both valves.
7) Stop vacuum pump. Disconnect center charging hose from pump inlet. No w, the system is ready for
charging refrigerant.
Checking A/C System for Pressure Leaks
After completing the evacuation, close manifold gauge
high pressure valve and low pressure valve and wait 10
minutes. Verify that low pressure gauge reading has not
changed.
CAUTION!
If the gauge reading moves closer to “0”,
there is a leak somewhere. Inspect the tubing
connections and make necessary
corrections. And then, evacuate system once
again and make sure that there are no leaks.

Removal of Manifold Gauge Set
WARNING!
High pressure side is under high pressure.
Therefore, be careful not to get injured
especially on your eyes and skin.

For the A/C system charged with the specified amount of
refrigerant, remove manifold gauge set as follows:
1) Close low pressure side valve of manifold gauge set. (The high pressure side valve is closed continuously
during the process of charging.)
2) Close refrigerant container valve.
3) Stop engine.
4) Using shop rag, remove charging hoses from service valves. This operation must be performed quickly.
5) Put caps on service valves.
Check A/C System for Refrigerant Leaks
Whenever a refrigerant leak is suspected in the system
or any service operation has been performed which may
result in malfunction of lines and connections, it is
advisable to check for leaks.
Common sense should be used during refrigerant leak
test, since the need and extent of any such test will, in
general, depend upon the nature of a complaint and the
type of a service performed on the system.
Liquid leak detector
WARNING!
• To prevent explosions and fires, make sure that there are no flammables in the vicinity.
• When the refrigerant exposed to fire, it turns into a poisonous gas (phosgene). Do
not inhale this gas.

There is a number of fittings and places throughout the
A/C system where a liquid leak detector solution may be
used to pinpoint refrigerant leaks.
By merely applying the solution to the area in question
with a swab, such as attached to the cap of a vial,
bubbles will form within seconds if there is a leak.
For confined areas, such as sections of the evaporator
and condenser, an electronic (refrigerant) leak detector
is more practical fo r determining leaks.

General Description
Auto A/C System DescriptionS7RS0B7221001
The automatic type air conditioning system (auto A/C) is pr ovided with the function to automatically control the inside
air temperature, fan speed, air flow outl et direction and air intake position by HVAC control module in addition to
functions of the manual type air conditioning system (manua l A/C). Once the inside air temperature is set using the
temperature selector, HVAC control module automatically controls the inside air temperature at the constant level at all
times based on the inside air temperature, outside ai r temperature, amount of sunlight and engine coolant
temperature detected respectively by the inside air te mperature sensor, outside air temperature sensor, sunload
sensor and ECT sensor. At this time, “FULL AUTO A/ C” appears on the display of HVAC control module.
With the air intake selector pushed in the above state, it is possible to select any position of the air intake actuator.
Then, “FULL AUTO A/C” on the display changes to “AUTO A/C”.

Precautions
Precautions on Service and Diagnosis of Air
Bag System
S7RS0B8200001
WARNING!
• If the air bag system and another vehicle system both need repair, SUZUKI
recommends that the air bag system be
repaired first, to help avoid unintended air
bag system activation.
• Do not modify the steering wheel, dashboard, both front seat or any other on
or around air bag system components.
Modifications can adversely affect air bag
system performance and lead to injury.
• Be sure to follow the procedures described in this section. Failure to follow
procedures could result in possible air bag
system activation, personal injury or
unneeded air bag system repairs.

• WARNING / CAUTION labels are attached on each
part of air bag system components (SDM, air bag
(inflator) modules and seat belt pretensioners). Be
sure to follow the instructions.
• Many of service procedures require disconnection of
“A/BAG” fuse and air bag (inflator) module(s) (driver,
passenger, side of both si des and curtain of both
sides) from initiator circuit to avoid an accidental
deployment.
• Do not apply power to the air bag system unless all components are connected or a diagnostic flow
requests it, as this will set a DTC.
• The “Air Bag Diagnostic S ystem Check” must be the
starting point of any air bag diagnostics. The “Air Bag
Diagnostic System Check” will verify proper “AIR
BAG” warning right operatio n and will lead you to the
correct flow to diagnose any air bag malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacements. • Never use air bag component parts from another
vehicle.
• If the vehicle will be exposed to temperatures over 93
° C (200 °F) (for example, during a paint baking
process), remove the air bag system components
beforehand to avoid component damage or
unintended system activation.
• When handling the air bag (inflator) modules (driver, passenger, side of both si des and curtain of both
sides), seat belt pretensio ners (driver and passenger),
SDM, forward-sensor or side-sensor, be careful not to
drop it or apply an impact to it. If an excessive impact
was applied (e.g., SDM, forward-sensor and side-
sensor are dropped, air bag (inflator) module is
dropped from a height of 90 cm (3 ft) or more, seat
belt pretensioner (retractor assembly) is dropped from
a height of 30 cm (1 ft) or more), never attempt
disassembly or repair but replace it with a new one.
• When using electric welding, be sure to disconnect air bag (inflator) module connectors (driver, passenger,
side of both sides and curtain of both sides) and seat
belt pretensioner connectors (driver and passenger)
respectively.
• When applying paint around the air bag system related parts, use care so that the harness or
connector will not be expo sed to the paint mist.
• Never expose air bag system component parts directly to hot air (drying or baking the vehicle after
painting) or flames.
WARNING!
When performing service on or around air
bag system components or air bag wiring,
follow the procedures listed in “Disabling Air
Bag System” to temporarily disable the air
bag system.
Failure to follow procedures could result in
possible air bag system activation, personal
injury or unneeded air bag system repairs.
