6) Replenish oil until oil level is brought to FULL level mark on
dipstick. (oil pan and oil filter capacity). The filler inlet is at
the top of the cylinder head cover.
It is recommended to use engine oil of SE, SF, SG, SH or SJ
grade.
NOTE:
Select the appropriate oil viscosity according to the proper
engine oil viscosity chart [A].
Engine oil specification :
7) Check oil filter and drain plug for oil leakage.
8) Start engine and run it for 3 minutes. Stop it and wait 5 min-
utes before checking oil level. Add oil, as necessary, to bring
oil level to FULL level mark on dipstick.

Refrigerant Recovery, Evacuation and Charging
Operation Procedure for Charging A/C with Refrigerant
WARNING:
Your eyes should not be exposed to refrigerant (liquid).
Any liquid Refrigerant-134a escaping by accident shows a temperature as low as approx. –6 °C
(21.2 °F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause a
serious injury. To protect your eyes against such accident, it is necessary to always wear goggles.
Should it occur that HFC-134a (R-134a) strikes your eye(s), consult a doctor immediately.
–Do not use your hand to rub the affected eye(s). Instead, use quantities of fresh cold water to
splash it over the affected area to gradually raise temperature of such area above freezing point.
–Obtain proper treatment as soon as possible from a doctor or eye specialist.
Should the HFC-134a (R-134a) liquid come into contact with your skin, the affected area should be
treated in the same manner as when skin is frostbitten or frozen.
Refrigerant must not be handled near where welding or steam cleaning is performed.
Refrigerant should be kept at a cold and dark place. It should never be stored where a high temper-
ature is anticipated, e.g. where exposed to direct sun light, close to fire or inside vehicle (including
trunk room).
Avoid breathing fumes produced when HFC-134a (R-134a) is burned. Such fumes may be hazardous
to health.
Start evacuating
Charge proper amount of refrigerant
in gas form
Amount of refrigerant
Dual A/C model : 750±50g (1.65±0.11 lb, 26.45±1.76 oz)
Single A/C model : 500±50g (1.1±0.11 lb, 17.64±1.76 oz)

Inspect and repair connections Stop evacuating
Performance test
Check system for pressure tightness
Charge A/C with refrigerant
Check system for refrigerant leaks and
refrigerant charging quantity

Wait 10 minutes

AIR CONDITIONING (OPTIONAL) 1B-21
Evacuating
Evacuating procedure
1) Connect high charging hose (1) and low charging hose (2) of
manifold gauge set (3) respectively as follows:
High Charging Hose (1) → High pressure charging valve (4)
on Discharge Hose
Low Charging Hose (2) → Low pressure charging valve (5)
on Suction Pipe
2) Attach center charging hose (6) of manifold gauge set (3) to
vacuum pump (7).
3) Operate vacuum pump (7), and then open discharge-side
valve (9) (Hi) of manifold gauge set (3).
If there is no blockage in the system, there will be an indica-
tion on high pressure gauge (10).
When this occurs, open the other-side valve (8) (Lo) of the
set.
4) Approx. 10 minutes later, low pressure gauge (11) should
show –10 kPa (–1.0 kg/cm
2, –760 mmHg, –14.2 psi) provid-
ing no leakage exists.
5) Evacuation should be carried out for a total of at least 20
minutes.
6) Continue evacuation until low pressure gauge indicates –10
kPa (–1.0 kg/cm
2, –760 mmHg, –14.2 psi), and then close
both valves (8), (9).
7) Stop vacuum pump (7). Disconnect center charging hose (6)
from pump inlet. Now, the system is ready for charging refrig-
erant. CAUTION:
Do not evacuate before recovering refrigerant in system.
NOTE:
Whenever opened (exposed to atmospheric air), air con-
ditioning system must be evacuated by using a vacuum
pump. The A/C system should be attached with a mani-
fold gauge set, and should be evacuated for approx. 20
minutes.
NOTE:
If the system does not show –10 kPa (–1.0 kg/cm
2, –
760 mmHg, –14.2 psi), close both valves, stop vacuum
pump and watch movement of low pressure gauge.
Increase in the gauge reading suggests existence of
leakage. In this case, repair the system before continu-
ing its evacuation.
If the gauge shows a stable reading (suggesting no
leakage), continue evacuation.

1B-22 AIR CONDITIONING (OPTIONAL)
Checking system for pressure leaks
After completing the evacuation, close manifold gauge high pres-
sure valve (HI) and low-pressure valve (LO) and wait 10 minutes.
Verify that low-pressure gauge reading has not changed.
Charging
CAUTION:
If the gauge reading moves closer to “0”, there is a leak
somewhere. Inspect the tubing connections, make nec-
essary corrections, and evacuate system once again,
making sure that there are no leaks.
CAUTION:
ALWAYS CHARGE THROUGH LOW PRESSURE-SIDE of A/C system at after the initial charging is
performed from the high-pressure side with the engine stopped.
NEVER CHARGE TO HIGH PRESSURE-SIDE of A/C system with engine running.
Do not charge while compressor is hot.
When installing tap valve to refrigerant container to make a hole there through, carefully follow
directions given by manufacturer.
A pressure gauge should always be used before and during charging.
The refrigerant container should be emptied of refrigerant when discarding it.
The refrigerant container should not be heated up to 40 °C (104 °F) or over.
Refrigerant container should not be reversed in direction during charging. Reversing in direction
causes liquid refrigerant to enter compressor, causing troubles, such as compression of liquid
refrigerant and the like.
NOTE:
The air conditioning system contains HFC-134a (R-134a).
Described here is a method to charge the air conditioning system with refrigerant from the refrigerant
service container.
When charging refrigerant recovered by using the refrigerant and recycling equipment (when recy-
cling refrigerant), follow the procedure described in the equipment manufacturer’s instruction manual.

AIR CONDITIONING (OPTIONAL) 1B-23
The initial charging of the A/C system is performed from the high-
pressure side with the engine stopped.
And next, this method must be followed by charging from the low-
pressure side with the engine running.
1) Check to make sure that hoses are routed properly after
evacuating the system.
2) Connect Low-side hose (1) and High side hose (2) of the
manifold gauge set (3) in position. Thus open refrigerant
container valve (4) to purge the charging line.
3) Open the high-pressure side valve (6) and charge refrigerant
to system.
4) After a while, open the low-pressure side valve (5) and close
the high-pressure side valve (6).
5) Start engine and keep engine speed at 1500 rpm. Then,
operate air conditioning.
6) Charge A/C system with refrigerant in vapor state. At this
time, refrigerant container should be held upright.
7) When refrigerant container (3) is emptied, the use following
procedure to replace it with a new refrigerant container (3).
a) Close low pressure valve.
b) Replace empty container (3) with a refrigerant container
which has been charged with refrigerant. When using
refrigerant container tap valve (4), use following procedure
for replacement.
i) Retract needle (1) and remove refrigerant container tap
valve (4) by loosening its plate nut (2).
ii) Install previously-removed refrigerant container tap valve
(4) to a new refrigerant container (3). WARNING:
Make sure that high pressure-side valve is closed
securely.
NOTE:
Dual A/C model must be operated rear A/C system, too.
