General Precautions
The WARNING and CAUTION below describe some general precautions that you should observe when servic-
ing a vehicle. These general precautions apply to many of the service procedures described in this manual, and
they will not necessarily be repeated with each procedure to which they apply.
 Before starting any service work, cover fenders, seats
and any other parts that are likely to get scratched or
stained during servicing. Also, be aware that what you
wear (e.g, buttons) may cause damage to the vehicle’s
finish.
 When performing service to electrical parts that does
not require use of battery power, disconnect the nega-
tive cable of the battery. WARNING:
 Whenever raising a vehicle for service, be sure to follow the instructions under “Vehicle Lifting
Points” in this section.
 When it is necessary to do service work with the engine running, make sure that the parking brake
is set fully and the transmission is in Neutral (for manual transmission vehicles) or Park (for auto-
matic transmission vehicles), Keep hands, hair, clothing, tools, etc. away from the fan and belts
when the engine is running.
 When it is necessary to run the engine indoors, make sure that the exhaust gas is forced outdoors.
 Do not perform service work in areas where combustible materials can come in contact with a hot
exhaust system. When working with toxic or flammable materials (such as gasoline and refriger-
ant), make sure that the area you work in is well-ventilated.
 To avoid getting burned, keep away from hot metal parts such as the radiator, exhaust manifold,
tailpipe, muffler, etc.
 New and used engine oil can be hazardous. Children and pets may be harmed by swallowing new or
used oil. Keep new and used oil and used engine oil filters away from children and pets.
Continuous contact with used engine oil has been found to cause [skin] cancer in laboratory ani-
mals. Brief contact with used oil may irritate skin. To minimize your exposure to used engine oil,
wear a long-sleeve shirt and moisture-proof gloves (such as dish washing gloves) when changing
engine oil. If engine oil contacts your skin, wash thoroughly with soap and water. Launder any
clothing or rags if wet with oil, recycle or properly dispose of used oil and filters.
 Make sure the bonnet is fully closed and latched before driving. If it is not, it can fly up unexpectedly
during driving, obstructing your view and resulting in an accident.

1) Confirm that vehicle and environmental conditions are as fol-
lows.
Vehicle is not exposed to direct sun.
Ambient temperature is within 15 – 35 °C (59 – 95 °F).
2) Make sure that high pressure valve (1) and low pressure
valve (2) of manifold gauge set (3) are firmly closed.
3) Connect high pressure charging hose (4) to high pressure
service valve (5), and connect low pressure charging hose
(6) to low pressure service valve (7).
4) Bleed the air in charging hoses (4), (6) by loosening their
respective nuts on manifold gauge set (3), utilizing the refrig-
erant pressure. When a hissing sound is heard, immediately
tighten nut.
5) Warm up engine to normal operating temperature (engine
coolant temperature at 80 – 90 °C (176 – 194 °F)) and keep
it at specified idle speed. (Radiator cooling fan should not be
working when checking pressure and temperature.)
6) Turn A/C switch ON, and set blower switch at “HI” (3rd posi-
tion), temperature knob at “COOL” air outlet control knob at
“FACE” and fresh / circulation control knob at “CIRCULA-
TION”. (Confirm that A/C compressor and radiator / con-
denser cooling fan are working.)
Keep all windows, doors and engine food open.

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 hose
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 (Hi) (8) of manifold gauge set (3).
If there is no blockage in the system, there will be an indica-
tion on high pressure gauge (9).
In this case, open the other side valve (Lo) (10) of the set
and repair the system.
4) Approximately 10 minutes later, low pressure gauge (11)
should show a vacuum lower than –760 mmHg providing no
leakage exists.
5) Evacuation should be carried out for a total of at least 15
minutes.
6) Continue evacuation until low pressure gauge (9) indicates a
vacuum less than –760 mmHg, and then close both valves
(8), (10).
7) Stop vacuum pump (7). Disconnect center charging hose (6)
from pump inlet. Now, the system is ready for charging refrig-
erant. NOTE:
 If the system does not show a vacuum below –760
mmHg, 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.

2) Connect Low charging hose (1) and High charging hose (2)
of the manifold gauge set (3) in position. Thus open refriger-
ant container valve (4) to purge the charging line.
3) Open the high pressure side valve (5) and charge refrigerant
to system.
4) After a while, open the low pressure side valve (6) and close
the high pressure side valve (5).
5) Start engine and keep engine speed at 1500 r/min. 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, use the following
procedure to replace refrigerant container with a new refrig-
erant 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 the following proce-
dure 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).
c) Purge any air existing in center charging hose
When using refrigerant container tap valve, use the follow-
ing procedure to purge air.
i) Once fully tighten refrigerant container tap valve (1), and
then loosen (open) plate nut (2) slightly.
ii) Open low pressure side valve (3) of manifold gauge set
(4) a little.
iii) As soon as refrigerant comes out with a “hiss” through a
clearance between refrigerant container and tap valve,
tighten plate nut (2) as well as low pressure side valve (3).
iv) Turn handle of tap valve (1) clockwise so that its needle is
screwed into the new container to make a hole for refriger-
ant flow. WARNING:
Make sure that high pressure side valve is closed
securely.

Removing Manifold Gauge Set
When A/C system has been charged with a specified amount of
refrigerant, remove manifold gauge set as follows:
1) Close low pressure side valve of manifold gauge set. (The
high pressure side valve is closed continuously during the
process of charging.)
2) Close refrigerant container valve.
3) Stop engine.
4) Using shop rag, remove charging hoses from service valves.
This operation must be performed rapidly.
5) Put caps on service valves.
Leak Test
Whenever a refrigerant leak is suspected in the system or any
service operation has been performed which may result in dis-
turbing lines or connections, it is advisable to test for leaks.
Common sense should be used in performing any refrigerant leak
test, since the need and extent of any such test will, in general,
depend upon the nature of a complaint and the type of a service
performed on the system.
LIQUID LEAK DETECTOR
There are a number of fittings and places throughout the air con-
ditioning system where a liquid leak detector solution may be
used to pinpoint refrigerant leaks.
By merely applying the solution to the area in question with a
swab, such as attached to the cap of a vial, bubbles will form
within seconds if there is a leak.
For confined areas, such as sections of the evaporator and con-
denser, an electronic (refrigerant) leak detector (1) is more practi-
cal for determining leaks.WARNING:
High pressure side is naturally under high pressure. So,
care must be used to protect your eyes and skin.

General Description
4WD Control System
The 4WD control system consists of a 4WD switch, a vacuum switch, a vacuum tank, two vacuum switching
valves (VSV1 and VSV2) and air locking hub assemblies.
The 4WD controller controls locking or unlocking of the air locking hub according to operation of the transfer shift
control lever.
Vacuum generated in the intake manifold passes through the check valve and stored in the vacuum tank.
According to signals from the 4WD switch, the 4WD controller activates VSV1 (for unlocking) or VSV2 (for lock-
ing) to apply vacuum from the vacuum tank so that the front axle and the wheel hub are disengaged or engaged.
