AIR CONDITIONING 1B-1
SECTION 1B
AIR CONDITIONING
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 of 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 of 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 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 mainte-
nance. 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 vehicle being serv-
iced. Use of incorrect one will result in leakage of refrigerant, damage in parts or other faulty condi-
tion.
