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, SJ or
SL grade.
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 three minutes. Stop it and wait five
minutes before checking oil level. Add oil, as necessary, to
bring oil level to FULL level mark on dipstick.
Engine Coolant
CHANGE
Change engine coolant referring to “Cooling System Flush and
Refill” in Section 6B.
Exhaust System
INSPECTION
Oil pan capacity About 3.8 liters (8.0/6.7 US/lmp pt.)
Oil filter capacity About 0.2 liters (0.4/0.3 US/lmp pt.)
Others About 0.3 liters (0.6/0.5 US/lmp pt.)
Total About 4.3 liters (9.1/7.6 US/lmp pt.)
NOTE:
Engine oil capacity is specified. However, note that the
amount of oil required when actually changing oil may
somewhat differ from the data in the table depending on
various conditions (temperature, viscosity, etc.)
1. Full level mark (hole)
2. Low level mark (hole)
WARNING:
To avoid danger of being burned, do not touch exhaust
system when it is still hot. Any service on exhaust sys-
tem should be performed when it is cool.

General Description
The heater, an in and out air selectable-type hot water heater, is so constructed that it is possible to assure an
agreeable ventilation at all times by providing the ventilator air outlets at the center and both sides (right and left)
of the instrument panel, the hot air outlet at a place close to the feet of front passengers, and the defroster air
outlets at places, right and left, along the windshield glass.
The heater and ventilation consist of following parts.
1. Side ventilator outlet 6. Ventilator duct 11. Heater core
2. Side defroster outlet 7. Control lever 12. Damper
3. Center ventilator outlet 8. Blower motor 13. Air inlet box (without air conditioning, without
other parts marked *)/cooling unit (if equipped
with air conditioning) 4. Heater unit 9. Blower resistor
5. Defroster duct 10. Blower fan switch/Blower fan and A/C
switch (if equipped with air conditioning)

Quick Checking of Refrigerant Charge
The following procedure can be used for quickly checking whether
the A/C system has a proper charge of refrigerant or not.
Run engine at fast idle, and operate A/C at its maximum cooling
capacity for a few minutes. Then, look at the sight glass (1) on
receiver / dryer (2) and compare what is observed with the symp-
toms listed in below.
CHECKING REFRIGERANT CHARGE
3. Bubbles
Symptom Charge of refrigerant condition Correction
Bubbles observed in sight glass Insufficient charge of refrigerant in
systemCheck system for leaks with a
leak tester.
No bubbles observed in sight glass No or insufficient charge of refrig-
erant in systemRefer to the items 3 and 4.
No temperature difference between
compressor inlet and outletEmpty or nearly empty system Evacuate and charge system and
then check it for leaks with a leak
tester.
Noticeable temperature difference
between compressor inlet and outletProper or too much charge of
refrigerant in systemRefer to the items 5 and 6.
When A/C is turned OFF, refrigerant in
sight glass clears immediately and
remains clearToo much charge of refrigerant in
systemDischarge excess refrigerant in
order to obtain a specified charge.
When A/C is turned OFF, refrigerant in
sight glass once produces bubbles and
then clearsProper charge of refrigerant in
systemNo correction needed because
charge of refrigerant is normal.
