AIR CONDITIONING (OPTIONAL)
WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System :
• Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to "Air Bag System Components and Wiring Location View" under
"General Description" in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and "Ser-
vice Precautions" under "On-Vehicle Service" in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
• Technical service work must be started at least 90 seconds after the ignition switch is turned to the
"LOCK" position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
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 mainte-
nance. For identification between these two types, refer to "REFRIGERANT TYPE" in this section.
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.
NOTE:
For basic servicing method of the air conditioning system that is not described in this section, refer to
"AIR CONDITIONING BASIC MANUAL (Part number : 99520-02130)".
