This vehicle uses HFC-134a (R-134a) refrigerant which does not contain chlorofluorocarbons. Pay attention to the follow-ing service items:
. Do not mix refrigerants CFC-12 (R-12) and HFC-134a (R-134a). They are not compatible.. Use only the recommended polyalkyleneglycol (PAG) refrigerant oil (ND-OIL 8: P/N 38897-PR7-A01AH or 38899-PR7-A01) designed for the R-134a compressor. Intermixing the recommended (PAG) refrigerant oil with any other refriger-ant oil will result in compressor failure.
. All AVC system parts (compressor, discharge line, suction line. evaporator, condenser, receiver/dryer, expansion valve.O-rings for joints) have to be proper for refrigerant R-134a. Do not confuse with R-12 parts.
. Use a halogen gas leak detector designed for refrigerant R-134a.. R-12 and R-134a refrigerant servicing equipment are not interchangeable. Use only a Recovery/Recycling/ChargingSystem that is U.L.-listed and is certified to meet the requirements of SAE J2210 to service R-134a air conditioning sys-tems.
. Always recover the refrigerant R-134a with an approved Recovery/Recycling/Charging System before disconnectingany Ay'C fitting.

Remove the relief valve and the O-ring. Plug the
opening to keep foreign matter from entering the
system and the compressor oil from running out,
NOTE:
. Do not let the compressor oil run out.
. Make sure there is no foreign matter in the sys-
tem.

ChargingLeak Test
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner system.
CAUTION: Exposure to air conditioner refrig6rant and
lubricant vapol or mist can irritate eyes. nose and
throat. Avoid broating the air conditione. relrigerant
and lubricant vapor o; 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 mixtures of air and R-1348 have
been shown to be combustible at €levat€d pre3sures
and can rosult in fire or explosion causing iniury or
property damage. Never use compressed air to pressure
test R-134a s€rvics oquipment or vehicle air conditioner
Systems.
Additional health and safety information may be
obtained from the refrigerant and lubricant manufac-
rures.
Connect a R-134a refrigerant Recovery/Recycling/
Charging System to the vehicle, as shown in the pre-
vious column, following the equipment manufactur-
er's instructions.
NOTE: Be sure to install the same amount of new
refrigerant oil back into the A/C system before
charging.
Open high pressure valve to charge the system to
the specified capacity, then close the supply valve,
and remove the charging system couplers.
R€frigerani capacity: 700 1o g 124.7 llroz)
Check the system for leaks using a R-134a refriger-
ant leak detector with an accuracy of 14 g (0.5 oz)
per year or better.
lf you find leaks that require the system to be
opened (to repair or replace houses. fittings, etc.),
recover the system according to the Recover
Procedure on page 22-22.
After checking and repairing leaks, the system must
be evacuated (see System Evacuation on page 22-
38).
JUse only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner system.
CAUTION: Exposure to air conditioner r€frigsrant and
lubricant vapol or mist can irritate eyos, nose and
throat. Avoid broathing the air conditioner reftigerant
