LUBRICATION AND MAINTENANCE

M1001001200336

Maintenance and lubrication service recommenda-
tions have been compiled to provide maximum pro-
tection for the vehicle owner's investment against all
reasonable types of driving conditions. Since these
conditions vary with the individual vehicle owner's
driving habits, the area in which the vehicle is oper-
ated and the type of driving to which the vehicle is
subjected, it is necessary to prescribe lubrication and
maintenance service on a time frequency as well as
mileage interval basis.
Oils, lubricants and greases are classified and
graded according to standards recommended by the
Society of Automotive Engineers (SAE) and the Aus-
tralian Petroleum Institute (API).

MAINTENANCE SCHEDULES

For Information on service maintenance refer to the
"Service handbook".

ENGINE OIL

CAUTION

Tests have shown that laboratory animals
develop skin cancer after prolonged contact with
used engine oil. Accordingly, the potential exists
for humans to develop a number of skin disor-
ders, including cancer, from such exposure to
used engine oil. Therefore, when changing
engine oil, be careful not to touch it as much as
possible. Protective clothing and gloves, that
cannot be penetrated by oil, should be worn. The
skin should be thoroughly washed with soap and
water, or use waterless hand cleaner, to remove
any used engine oil. Do not use petrol, thinners,
or solvents.

Either of the following engine oils should be used:
1. Engine oil conforming to the ACEA classification:

"For service A1, A2 or A3.

2. Engine oil conforming to the API classification:

"For service SG" or higher.

FUEL USAGE STATEMENT

CAUTION

Using leaded petrol in this car will damage the
catalytic converters and heated oxygen sensors,
and affect the warranty coverage validity.
This vehicle must use unleaded petrol only.
This vehicle has a fuel filler tube which is especially
designed to accept only the smaller-diameter
unleaded petrol dispensing nozzle.
The 3.8L model is designed to operate on unleaded
petrol having an octane rating (DIN 51607) of 90
RON or higher.

.

PETROL CONTAINING ALCOHOL

Some petrol sold at service stations contain alcohol
although they may not be so identified.
Using fuels containing alcohol is not recommended
unless the nature of the blend can be determined as
being satisfactory, as follows.
Gasohol: A mixture of 10% ethanol and 90%
unleaded gasoline may be used in your vehicle. If
driveability problems are experienced as a result of
using gasohol, it is recommended that the vehicle be
operated on petrol.
Methanol: Do not use petrol containing methanol
(wood alcohol). Using this type of alcohol can result
in vehicle performance deterioration and damage
critical parts in the fuel system components. Fuel
system damage and performance problems resulting
from the use of petrol containing methanol may not
be covered by the new vehicle warranty.

MATERIALS ADDED TO FUEL

Indiscriminate use of fuel system cleaning agents
should be avoided. Many materials intended for gum
and varnish removal may contain highly active sol-
vents or similar ingredients that can be harmful to
gasket and diaphragm materials used in fuel system
component parts.

SELECTION OF COOLANT

.

COOLANT

Relationship between Coolant Concentration and Specific Gravity

CAUTION

• If the concentration of the coolant is below 30%, the anti-corrosion property will be adversely

affected. In addition, if the concentration is above 50%, both the anti-freeze and engine cooling
properties will decrease, affecting the engine adversely. For these reasons, be sure to maintain
the concentration level within the specified range.

• Do not use a mixture of different brands of anti-freeze.

Example
The safe operating temperature is

−15°C (5° F) when the specific gravity is 1.058 at the coolant temperature

of 20

MAINTENANCE SERVICE

GENERAL

MAINTENANCE SERVICE

1. FUEL SYSTEM (TANK, PIPE LINE AND
CONNECTION, AND FUEL TANK FILLER TUBE
CAP) (CHECK FOR LEAKS)

M1001001600312

Check for damage or leakage in the fuel lines and connections.

2. FUEL HOSES (CHECK CONDITION)

M1001001700308

1. Inspect the surface of fuel hoses for heat and mechanical

damage. Hard and brittle rubber, cracking, tears, cuts,
abrasions and excessive swelling indicate deterioration of
the rubber.

2. If the fabric casing of the rubber hose is exposed by cracks

and abrasions in the fuel system, the hose should be
replaced.

3. AIR CLEANER FILTER (REPLACE)

M1001001800338

The air cleaner element will become dirty during use, reducing
its effectiveness. Replace it with a new one.
REPLACEMENT OF AIR CLEANER ELEMENT
1. Unclamp the air cleaner housing cover.

2. Remove the air cleaner element and install a new one.

3. When clamping the air cleaner housing cover in place, be

sure that the cover is completely closed.

4. EVAPORATIVE EMISSION CANISTER (CHECK
FOR CLOGGING)

M1001001900324

If the fuel-vapor cannister is clogged or damaged, excess fuel
vapor will escape into the atmosphere causing a strong fuel
vapour smell t emitt from engine compartmrnt. emission. Dis-
connect the line at both ends, and blow it clean with com-
pressed air. Remove the fuel tank filler tube cap from the filler
tube and check to see if there is evidence that the seal makes
improper contact to the filler tube.
