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.

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.

Health Warning
Prolonged and repeated contact with mineral oil
will result in the removal of natural fats from the
skin, leading to dryness, irritation and dermatitis .
In addition, used engine oil
potentially
Recommended Precautions
The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example
by using enclosed systems for handling used engine
oil and by degreasing components, where
practicable, before handling them.
Other precautions:
lAvoid prolonged and repeated contact with oils,
particularly used engine oils.
l Wear protective clothing, including impervious
gloves where practicable.
l Avoid contaminating clothes, particularly
underpants, with oil.
l Do not put oily rags in packets, the use of
overalls without pockets will avoid this.
l Do not wear heavily soiled clothing and
oil-impregnated foot-wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.
LUBRICANTS

provided.
Where there is a risk of eye contact, eye protection should be worn, for example,
chemical goggles or face shields; in addition
an eye wash facility should be provided.
Obtain First Aid treatment immediately for open
cuts and wounds.
Wash regularly with soap and water to ensure
all oil is removed, especially before
cleansers and nail brushes will help). After
cleaning, the application of
containing lanolin to replace the natural
oil is advised.. .
Do not use gasoline, kerosine, diesel fuel,
oil, thinners or solvents for cleaning skin.
Use barrier creams, applying them before each
work period, to help the removal of oil from
the skin after work.
If skin disorders develop, obtain medical advice
without delay.
