LUBRICATION AND
MAINTE-
NANCEMOOPA-
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
vehicle owner’s driving habits, the area in which the
vehicle is operated 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), the Amer-
ican 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”.
The item numbers used in the “SCHEDULED MAINTENANCE TABLE” correspond to th
e
“MAINTENANCE SERVICE” section numbers.
SEVERE SERVICE
Vehicles operating under severe service conditions
will require more frequent service. Component service information
isIncluded i
n
appropriate units for vehicles operating under one or
more of the following conditrons:
1.Trailer towing or police, taxi, or
commerciai
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 traffic during hot weather above
32°C (90°F)
(3) Extensive idling
(4) Driving in sandy areas
(5) Driving in salty areas
(6) Driving in dusty conditions
ENGINE OIL
The SAE grade number indicates the viscosity of engine oils, for example, SAE 30, which is a single
grade oil. Engine oils are also identified by a dual number, for example, SAE 1
OW-30, which Indicates
a multigrade oil.
The API classification system defines oil perform- ance in terms of engine usage. Only engine oil
designed “For Service SG” or “For Service
SGKD”,
when available, should be used. These oils contain
sufficient chemical additives to provide maximum
engine protection. Both the SAE grade and the API
designation can be found on the container.
Caution
Test results submitted to EPA have shown that
laboratory animals develop skin cancer after
prolonged contact with used engine oil. Accor-
dingly, the potential exists for humans to de-
velop a number of skin disorders, including
cancer, from such exposure to used engine oil.
Care should be taken, therefore, when changing engine oil, to minimize the amount and length of
exposure time to used engine oil on your skin.
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 gasoline,
thinners, or solvents.
GEAR LUBRICANTS
The SAE grade number also indicates the viscosity of Multi-Purpose Gear Lubricants.
The API classfication
system defines gear lubricants
in terms of usage. Typically gear lubricants conform-
ing to API
GL-4 or GL-5 with a viscosity of SAE 75W-85W
are recommended for manual transaxle.
LUBRICANTS
- GREASES
Semi-solid lubricants, bear the
NLGI designation and
are further classified as grades 0, 1, 2, 3 etc.
Whenever “Chassis Lubricant” is specified,
Multi-
Purpose Grease, NLGI grade 2 should be used.
FUEL USAGE STATEMENT
Your vehicle must use unleaded gasoline only.
This vehicle has a fuel filler tube especially designed
to accept only the smaller-diameter unleaded gaso- line
dispensrng nozzle.
Caution
Using leaded gasoline in your vehicle will damage
the catalytic converter, and affect the warranty
coverage validity.
All vehicles except those with DOHC engines
Your vehicle is designed to operate on unleaded
gasoline having a minimum octane rating of 87 or
91 RON (Research Octane Number).
Vehicles equipped with DOHC engines
Your vehicle is designed to operate on premiumunleaded gasoline having a minimum
octane rating
of 91 or 95 RON (Research Octane Number).

ENGINE OIL
Engine oil should be used which conform to the requirements
of the API classification “For Service SG” or “For Service
SGKD”, and have the proper SAE grade number for the
expected temperature range.
Caution
Nondetergent or straight mineral oil must never be used.
Energy Conserving Oil
In order to improve fuel economy and conserve energy new,
lower friction engine oils have been developed. These oils are readily available and can be identified by such labels as “Energy
Conserving”, “Energy Saving”,
“Improved Fuel Economy”,
etc.

Oil Identification Symbol
A standard
.symbol appears on the top of oil containers and has
three district areas for identifying various aspects of the oil.
The top
polqion will indicate the quality of the oil. The center
portion will show the SAE viscosity grade, such as SAE lOW-30.
“Energy Conserving” shown in the lower portion,
indicates that the oil has fuel-saving capabilities.

Cautions
1. If the concentration of the coolant is below 30%, the anti-corrosion property will be adversely
affected. In addition, if the concentration is above 60%, both the anti-freeze and engine cooling
properties will decrease, affecting the engine adversely. For these reas\
ons, be sure to maintain the
concentration level within the specified range.
2. Do not use a mixture of different brands of anti-freeze.

1.Check for damage or leakage in the fuel lines and con-
nections and looseness of the fuel tank filler tube cap.
2. Inspect the surface of fuel hoses for heat and mecha-
nicall damage. Hard and brittle rubber, cracking, check-
ing, tears, cuts, abrasions and excessive swelling
indicate deterioration of the rubber.
3. If the fabric casing of the rubber hose is exposed by cracks and abrasions in the fuel system, the hoses
should be changed.
3. AIR CLEANER ELEMENT (Replace)
MMlSAKH
The air cleaner element will become dirty and loaded with dust during use, and the filtering effect will be substantiallyreduced. Replace it with a new one.

(1) Loosen the clamp coupling the air intake hose and the air cleaner cover, and separate the hose.
(2) Disconnect the volume air flow sensor connectors.
(3) Unclamp the air cleaner cover clip.
(4) Lifting the air intake hose, remove the air cleaner cover.

TRANSAXLE
Inspect fluid levelMOOSSDA
1. Drive until the fluid temperature reaches the usual ternperature
[70-80°C (160- 18O”F)I.
2. Plaice vehicle on level floor.
3.Move selector lever sequentially to every position to fill
torque converter and hydraulic circuit with fluid, then place lever in “N” Neutral position. This operation is
necessary to be sure that fluid level check is accurate.
4. Before removing dipstick, wipe all dirt from area around
dipstick. Then take out the dipstick and check the
condition of the fluid.
The transaxle should be overhauled under the following
conditions.l If there is a “burning” odor.
l If the fluid color has become noticeably blacker.
l If there is a noticeably great amount of metal particles in the fluid.
5.Chleck to see if fluid level is in “HOT” range on dipstick.
If fluid level is low, add ATF until level reaches “HOT”
range.
LO\N fluid level can cause a variety of conditions
because it allows pump to take in air along with fluid. Air
trapped in hydraulic circuit forms bubbles which make
fluid spongy. Therefore, pressures will be erratic. Improper filling can also raise fluid level too high. When
transaxle has too much fluid, gears churn up foam and cause same conditions which occur with low fluid level,
resulting in accelerated deterioration of ATF.In either case, air bubbles can cause overheating, fluid
oxidation, which can interfere with normal valve, clutch,
and servo operation. Foaming can also result in fluid escaping from transaxle vent where it may be mistaken
for a leak.
6. Be sure to examine fluid on dipstick closely. Chaqge

Drain
tlhe fluid and check whether there is any evidence of
contamination. Replenish with new fluid after the cause of any contamina-
tion
has been corrected.
(1) Rernove drain plugs to let fluid drain.
(2) Rernove the oil pan.
(3) Check the oil filter for clogging and damage and replace
if necessary.
(4) Clean the inside of oil pan and 5 magnets.
(5) Attach the five magnets to the concave part of the oil
pan.

(6) Clean both gasket surfaces of transaxle case and oil
pan.
(7) Install oil pan with new gasket and tighten oil pan bolts
to
IO-I 2 Nm (7.5-8.5 ftlbs.)
(8) Tighten drain plug with gasket to 30-35 Nm (22-25 ft.lbs.).
(9) Supply 4
dm3 (4.23 qts.) of specified ATF into case
through dipstick hole. [Total quantity of ATF required is 6.1
dm3 (6.45 qts.).
Actually however, approx. 4.5 dm3 (4.76 qts.) of fluid
