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 service on or near the air bag system components or wiring. Please observe
all WARNINGS and "Service Precautions" under "On-Vehicle Service" in air bag system sec-
tion before performing service on or around the air bag system components or wiring. Fail-
ure 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 CFC-12 (R-12) and the other using refrigerant HFC-134a
(R-134a).
Be sure to check which refrigerant is used before any service work including inspection and
maintenance. For identification between these two types, refer to the description in page 1B-2.
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 ve-
hicle being serviced. Use of incorrect one will result in leakage of refrigerant, damage in parts
or other faulty condition.
For basic servicing method of the air conditioning system that is not described in this section, refer to AIR CONDI-
TIONING BASIC MANUAL (99520-02130).
