0A-6 GENERAL INFORMATION
Air bag wire harness can be identified easily as it is covered with a yellow protection tube. Be very
careful when handling it.
When an open in air bag wire harness, damaged wire harness, connector or terminal is found,
replace wire harness, connectors and terminals as an assembly.
Do not apply power to the air bag system unless all components are connected or a diagnostic chart
requests it, as this will set a diagnostic trouble code.
Never use air bag system component parts from another vehicle.
When using electric welding, be sure to temporarily disable air bag system referring to “DISABLING
AIR BAG SYSTEM” in Section 10B.
Never expose air bag system component parts directly to hot air (drying or baking the vehicle after
painting) or flames.
WARNING/CAUTION labels are attached on each part of air bag system components. Be sure to fol-
low the instructions.
After vehicle is completely repaired, perform “AIR BAG DIAGNOSTIC SYSTEM CHECK” in SECTION
10B.
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.
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, tail
pipe, 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 unexpect-
edly during driving, obstructing your view and resulting in an accident.

0B-8 MAINTENANCE AND LUBRICATION
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. 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.
ENGINE COOLANT
REPLACEMENT
NOTE:
For ambient temperature between –20°C (–4°F) and 30°C
(86°F), it is highly recommended to use SAE 10W – 30 oil.
Oil pan capacity About 3.6 liters (7.6/6.3 US/lmp pt.)
Oil filter capacity About 0.2 liter (0.4/0.3 US/lmp pt.)
Others About 0.3 liter (0.6/0.5 US/lmp pt.)
Total About 4.1 liters (8.7/7.2 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 help avoid danger of being burned, do not remove
radiator cap while engine and radiator are still hot. Scald-
ing fluid and steam can be blown out under pressure if
cap is taken off too soon.

MAINTENANCE AND LUBRICATION 0B-9
1) Remove radiator cap when engine is cool.
2) Loosen radiator drain plug (1) to drain coolant.
3) Remove reservoir and drain.
4) Tighten plug securely. Also reinstall reservoir.
5) Fill radiator with specified amount of coolant, and run engine
for 2 or 3 minutes at idle. This drives out any air which may
still be trapped within cooling system. STOP ENGINE.
Add coolant as necessary until coolant level reaches the
filler throat of radiator. Reinstall radiator cap.
6) Add coolant to reservoir so that its level aligns with Full
mark. Then, reinstall cap aligning arrow marks on reservoir
and cap. CAUTION:
When changing engine coolant, use mixture of 50% water
and 50% ANTIFREEZE/ANTICORROSION COOLANT for
the market where ambient temperature falls lower than –
16°C (3°F) in winter, and mixture of 70% water and 30%
ANTIFREEZE/ANTICORROSION COOLANT for the market
where ambient temperature doesn’t fall lower than –16°C
(3°F).
Even in a market where no freezing temperature is antici-
pated, mixture of 70% water and 30% ANTIFREEZE/ANTI-
CORROSION COOLANT should be used for the purpose
of corrosion protection and lubrication.

PERFORMANCE DIAGNOSIS
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 to ON position, and set blower fan switch at
“H” (4th position), temperature dial at “COOL”, air outlet con-
trol dial at “FACE” and fresh/recirculation control dial at
“RECIRCULATION”. (Confirm that A/C compressor and radi-
ator/condenser cooling fan are working.)
Keep all windows, doors and engine food open.
