GENERAL Lubrication arid Maintenance,
00100120067
Maintenance and lubrication service recommenda-
tions have been compiled to provide maximum
protection for the vehicle owner’s investment
against all reasonable types of driving conditions.
Since these conditions vary with the individual ve-
hicle owner’s driving habits, the area in which the
vehicle is operated and the type of to which
the vehicle is subjected, it is necessary to prescr ibe
lubrication and maintenance service on a time fre-
quency 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), the
American Petroleum Institute (API) and the National
Lubricating Grease Institute (NLGI).
MAINTENANCE SCHEDULES
Information for service maintenance is provided
under “SCHEDULED MAINTENANCE TABLE”.
Three schedules are provided; one for “Required
Maintenance”, one for “General Maintenance” and
one for “Severe Usage Service”. Item numbers in the “SCHEDULED MAINTE-
NANCE TABLE” correspond to the item
in the “MAINTENANCE SERVICE” section.
SEVERE SERVICE
Vehicles operating under severe service conditions
will require more frequent service. Component service information is included in ap-
propriate units for vehicles operating under one
or more of the following conditions:
1. Police, taxi, or commercial type operation
2. Operation of Vehicle
(1) Short-trip operation at freezing temperature
(engine not thoroughly warmed up)
(2) More than 50% operation in heavy city traf-
fic during hot weather above
(3) Extensive idling
(4) Driving in sandy areas
(5) Driving in salty areas
(6) Driving in dusty conditions
ENGINE OIL
Either of the following engine oils should be used:
(1) Engine oil displaying EOLCS certification mark
(2) Engine oil conforming to the API classification SH
or ECII.
For further details, refer to “LUBRICANTS SELEC-
TION” section.
Caution
Test to EPA have shown
laboratory animals develop skin after
prolonged contact with used engine oil. Accord-
ingly, the potential exists for
to
a number:, of skin disorders, including

Care should be taken, when changing
engine oil, to minimize the
of exposure time to used your
skin. Protective clothing and that
be penetrated by worn.
should be thoroughly with soap
use waterless hand remove,
any used engine oil. Do not use gasoline, thin- ners, or solvents.
GEAR LUBRICANTS
The SAE grade number indicates
of Multi-purpose Gear Lubricants.
The API classification system
cants in terms of gear lubricants
conforming to API
or ‘with a
of SAE are recommended for
transaxle.
LUBRICANTS GREASES
Semi-solid lubricants bear the
designation
and are further classified as grades 0, 1, 2; 3 etc .
Whenever “Chassis Lubricant” is specified, Multi-
purpose Grease,
grade 2, should be used.
FUEL USAGE
Your car must use unleaded
This car has a fuel filler tube especially
to accept only the smaller-diameter unleaded gaso- line dispensing nozzle.
Caution
Using leaded gasoline in your car will damage
the catalytic converter and oxygen sensor, and
affect the warranty coverage validity.
Your car is designed to operate on premium
leaded gasoline having a minimum octane rating
of 91 or 95 RON (Research Octane
If premium unleaded gasoline is not
leaded gasoline having a octane rating of 87,
91 RON (Research Octane Number) may be used. In this case, the performance and fuel consumption
will suffer a little degradation.
Gasolines Containing Alcohol
Some gasolines sold at service stations contain
alcohol, although they may not be so identified.
TSB Revision

Lubrication and
GENERAL Lubricants and Lubricant Capacities Table
Use of fuels containing alcohol is not recommended
unless the nature of the blend can be determined
as being satisfactory.
Gasohol
A mixture of 10% ethanol (grain alcohol)
and 90% unleaded gasoline may be used in your
car.
If problems are experienced as a result
of using gasohol, it is recommended that the car
be operated on gasoline.
Methanol Do not use gasolines containing
methanol (wood alcohol). Use of this type of alcohol
can result in vehicle performance deterioration and
damage critical parts in the fuel system compo-
nents. Fuel system damage and performance prob-
lems, resulting from the use of gasolines containin g
methanol, may not be covered by the new car war-
ranty.
Gasolines containing
Ether)
Unleaded gasoline containing 15% or
may be used in car. Fuel containing MTBE
over 15% vol. may cause reduced engine perfor-
mance and produce vapor lock or hard starting.
MATERIALS
TO FUEL
Indiscriminate use of fuel system -cleaning’
should be avoided. Many of these materials in-
tended for gum and varnish removal
highly active solvents or similar ingredients that
can be harmful to gasket and diaphragm materials
used in fuel system component

AIR CLEANER ELEMENT (Replace)00100180058
The air cleaner element become dirty and loaded with
dust during use, and the filtering effect will be
reduced.
Replace it with a new one.
(1) Unclamp the air cleaner cover.
(2) Take out the air cleaner element, install a new one.
(3) Be sure when clamping the air cleaner cover in place
that the cover is completed closed.
4.EVAPORATIVE EMISSION CONTROL SYSTEM
(Check for leaks and clogging)
except evapo-
rative emission canister
1.If the fuel-vapor vent line is clogged or damaged, a fuel
vapor mixture escapes into the atmosphere causing
excessive emissions. Disconnect the line at both en ds,
and blow it clean with compressed air. Remove the f uel
tank filler tube cap from the fuel tank filler tube and check
to see if there is evidence that the packing makes improper
contact to the fuel tank filler tube.
2.The fuel tank pressure control valve installed on the vapor
line should be checked for correct operation.
