SUPPLEMENTAL RESTRAINT SYSTEM (SRS}
The civic sRs includes a driver's airbag located in the steering wheel hub ln addition, all models (except some
models for canada) have a passenger's airbag located in the dashboard above the glove box'
Information necessary to safely service the sRS is included in this service Manual ltems marked with an asterisk (*)
on the contents page include, or are located near, sRs components. servicing, disassembling or replacing these
items will require special precautions and tools, and should therefore be done by an authorized Honda dealer'
@-";;il rendsring the SRS inoperative, which could lead to personal iniury or deaih in the svent of a sev€re
frontal collision. all SRS service work must be pertormed by an authorized Honda d€aler'
. lmploper service procedures, including incorrest removal and instsllation of the sRs, could lead to personal
iniury caused by unintentional deployment of the airbags'
o Do not bump the SRS unit. Otherwise. the system may fait in case of a collision. or the airbags may deploy
when the ignition switch is ON {ll}'
. sRs electrical wiring harncsses are id€ntified by yellow colol coding. Related components ale located in lhe
steering column, front console, dashboard, dashboald lowet panel, and in the dashboard above the glove box'
Do not use electricaltest equipment on these circuits.

A/C System Service
Performance Test
The performance test will help determine if the air con-
ditioner system is operating within specifications.
Use only service equipment that is U.L.-listed and is cer-
tified to meet the reouirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner system.
CAUTION: Exposure to air conditionor rofrigerant and
lubricant vapor or mist can irrilalo €yes, nose and
throat. Avoid breathing tho air conditioner rstrigerrnt
and lubricant vapor or mist,
lf accidental system discharge occurs, ventilate work
area before resuming service.
R-134a service equipment or vehicle air conditioner sys-
tems should not be pressure tested or leak tested with
compressed air.
@ some mixtur$ of air and R-134a have been
shown lo b9 combustible rt glgvatad pr€ssur63 and can
resull in tire 01 oxplosion causing inlury ot property
damage. Never uao compre33ed air to pressure t99t R-
134a ssrvico 6quipmsnt or vohicla air conditioner sys-
tems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.
'1. Connect a R-134a refrigerant recover/recycling/
charging station to the vehicle, as shown, following
the equipment manufacturer's instructions.
2. lnsert a thermometer in the center vent outlet.
Determine the relative humidity and air tempera-
ture,
Test conditions:
. Avoid direct sunlight.
. Open hood.
. Open front doors.
. Set the temDerature control lever or dial to MAX,
COOL, the mode control switch or dial on VENT
and the recirculation control switch on RECIRCU-
LATE.
. Turn the A,/C switch on. and the heater fan switch
on MAX.
. Run the engine at 1,500 rpm.
. No driver or passengers in vehicle
After running the air conditioning for 10 minutes
under the above test conditions, read the delivery
temperature from the thermometer in the dash vent
and the high and low system pressure from the A,/C
gauges.

Compressor (SANDENI
Replacement
1.lf the compressor is marginally operable, run the
engine at idle speed, and let the air conditioner
work for a few minutes. then shut the engine off.
Disconnect the negative cable from the battery.
Recover the refrigerant with a recovery/recycling/
charging station (see page 22-27l..
Remove the bolts, then disconnect the suction and
discharge lines from the compressor.
NOTE: Plug or cap the lines immediately after dis-
connecting them to avoid moisture and dust con-
tamination.

10. lnstall in the reverse order of removal. Make note of
the following items.
. lf you're installing a new compressor, drain all
the refrigerant oil from the removed compressor,
and measure its volume. Subtract the volume of
drained oil from '130m? 14 1/3 tl'o2,4 6 lmp'oz);
the result is the amount of oil you should drain
from the new compressor (through the suction
fifting).
. Replace the O-rings with new ones at each fit-
ting, and apply a thin coat of refrigerant oil
before installing them
NOTE: Be sure to use the right O-rings for HFC-
134a (R-134a) to avoid leakage
. Use refrigerant oil (SP-10) for R-134a Sanden and
Hadsys spiral type compressors only'
o To avoid contamination, do not return the oil to
the container once dispensed, and never mix it
with other refrigerant oils.
. lmmediatelY after using the oil, replace the cap
on the container, and seal it to avoid moisture
absorption.
. Do not spill the refrigerant oil on the vehicle; it
may damage the painu if the refrigerant oil con-
tacts the paint, wash it off immediately
. Adjust the Ay'C compressor belt (see page 22-43)
and the power steering pump belt (see section 17)'
. Charge the system (see page 22-46), and test its
oerformance (see Page 22-241

lf you're installing a new compressor. drain all therefrigerant oil from the removed compressor. andmeasure its volume. Subtract the volume ofdrained oil from '140 ml (4 28 fl{,z, 4.9 lmpoz); theresult is the amount of oil you should drain fromthe new compressor (through the suction fifting).Replace the O-rings with new ones at each fining,and apply a thin coat of refrigerant oil beforeinstalling them. Be sure to use the right O,ringsfor HFC-134a (R-134a) to avoid leakage.
Use refrigerant oil {DENSO, ND-OtL8) for HFC-134aDENSO piston type compressors only.To avoid contamination, do not return the oil tothe container once dispensed, and never mix itwith other refrigerant oils.
lmmediately after using the oil, replace the capon the container, and seal it to avoid moisture
absorption.
Do not spill the refrigerant oil on the vehicle; itmay damage the paint; if the refrigerant oil con-tacts the paint, wash it off immediatelv.
