Air Conditioning System
A/C System Caution
CAUTION
!
The air conditioning system of this vehicle
uses refrigerant HFC-134a (R-134a).
None of refrigerant, compressor oil and
component parts is interchangeable between
two types of A/C: one using refrigerant HFC-
134a (R-134a) and the other using refrigerant
CFC-12 (R-12).
Be sure to check which refrigerant is used
before any service work including inspection
and maintenance. For identification between
these two types, refer to "A/C Refrigerant
Type Description: ".
When replenishing or changing refrigerant
and compressor oil and when replacing
parts, make sure that the material or the part
to be used is appropriate to the A/C installed
in the vehicle being serviced.
Use of incorrect one will result in leakage of
refrigerant, damage in parts or other faulty
condition.
Precautions on Servicing A/C System
WARNING
!
Should refrigerant HFC-134a (R-134a) is
exposed to your eye(s), consult a doctor
immediately.
• Do not use your hand to rub affected
eye(s). Instead, use fresh cold water to
splash it over affected area to thus
gradually raise its temperature above the
freezing point.
• Obtain proper treatment as soon as
possible from a doctor or eye specialist.
Should liquid refrigerant HFC-134a (R-
134a) is exposed to your skin, such
affected part should be treated in the same
manner as when skin is frostbitten or
frozen.
Precautions
Precautions in Diagnosing Trouble
S5JB0A7200004
• Do not disconnect connector from HVAC control
module, battery cable from battery, or main fuse
before reading diagnostic information stored in HVAC
control module memory.
• When diagnosing vehicle indoors, sunload sensor has
to be lighted over vertically with an incandescent
lamp. Otherwise, DTC is detected even if sunload
sensor is normal.
• Diagnostic information (diagnostic trouble code)
stored in HVAC control module can be checked by
display of HVAC control module. Also, it can be
checked by using SUZUKI scan tool. Before checking
diagnostic information (diagnostic trouble code), read
this manual and operator's manual for SUZUKI scan
tool to know how to read diagnostic information
(diagnostic trouble code).
• When trouble is diagnosed using diagnostic
information (diagnostic trouble code) on display of
HVAC control module, keep in your mind that each
diagnostic information (diagnostic trouble code) has
priority, and only diagnostic information (diagnostic
trouble code) which has the highest priority is
indicated. Therefore, after troubleshooting the
malfunction, make sure if there exists any other
S5JB0A7200005
diagnostic information (diagnostic trouble code).
• After troubleshooting some trouble, DTC can be
stored in HVAC control module memory as history
DTC.
• Be sure to read "Precautions for Electrical Circuit
Service" before inspection.
Precautions on Handling Refrigerant HFC-134a
(R-134a)
• When handling refrigerant, always wear goggles to
protect your eyes.
• Avoid you direct contact to liquid refrigerant.
• Do not heat refrigerant container higher than 40 °C
(104 °F).
• Do not discharge refrigerant into atmosphere.
• Do not allow liquid refrigerant to touch bright metals.
Refrigerant combined with moisture is corrosive and
will tarnish surfaces of bright metals including chrome.
• After recovering refrigerant from system, the amount
of compressor oil removed must be measured and the
same amount added to the system.
