If premium unleaded gasoltne IS not available,
MATERIALS ADDED TO FUEL
unleaded gasoline having a octane rating of 87 or
91 RON (Research Octane Number) may be used. Indiscriminate use of fuel system cleaning agents
In this case, the performance and fuel consumption should be avoided. Many of these materials
in-
WIII suffer a little degradatron.tended for gum and varnish removal may contain
highly active
solvents or similar ingredients that can
be harmful to gasket and diaphragm materials used
in fuel system component parts.
Gasolines containing alcohol
Some gasolrnes sold at service stations contain
alcohol, although they may not be SC identified. Use
of fuels containing alcohol is not recommended
unless the nature of the blend can be
determrned
as being satisfactory.
Gasohol
- A mixture of 10% ethanol (grain alcohol)
and 90% unleaded gasoline may be used
In your
car. If
driveability 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 deteriora-
tion and damage critical parts in the fuel system
components. Fuel system damage and performance
problems, resulting from the use of gasolines
containing methanol, may not be covered by the
new car warranty.
Gasolines containing MTBE (Methyl Tertiary Butyl
Ether)
Unleaded gasolrne containrng
15% or less MTBE
may be used in your car. (Fuel containing MTBE
over 15% vol. may cause reduced engine per-
formance and produce vapor lock or hard starting.) RECOMMENDED

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
fluid
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
car1 be replaced because rest of fluid remains in torque converter.]

(1O)Star-t engine and allow to idle for at least two minutes.
Then, with parking brake on, move selector
fever
momentarily to each position, ending in “N” Neutral
position.
(11)Add sufficient ATF to bring fluid level to lower mark.
Recheck fluid level after transaxle is at normal Operating
temperature. Fluid level should be between upper and lower marks of
“HOT” range, Insert dipstick fully to prevent dirt from
entering transaxle.

COOLANT (Change)MOOSEEAC
Check the cooling system parts, such as radiator, heater,
and oil cooler hoses, thermostat and connections for
leakage and damage.
CHANGE COOLANT
1. Remove the radiator cap.
2. Loosen the drain plug to drain the coolant.
3. Drain the coolant from the reserve tank.
4. After draining the coolant, tighten the drain plug securely.
5.Supply the coolant into the radiator until it is filled up to
its filler neck.
6. Supply the coolant into the reserve tank.
7. After warming the engine until the thermostat opens, remove the radiator cap and check the coolant level.
8.Supply the coolant into the radiator until it is filled up to
its filler neck, and install the radiator cap securely.
9.Fill the reserve tank with coolant up to the “FULL” line.

Check for fluid contamination and wear. Replace complete
set of pads if defective.
Caution
The pads for the right and left wheels should be
reDlaced at the same time. Never “split” or intermix
brkke pad sets.
All four pads must be replace as a complete set.

1. Remove the brake drum and check the thickness of brake shoe lining for wear. Check the automatic brake
adjusting system by hand to see if it operates smoothly.
Also see if the gears are in proper mesh with each
other. To assure smooth functioning, apply a very thin
coat of multipurpose grease to the friction surface of
adjuster and link shaft.

OPERATION
l
The closed throttle position switch functions to
convert (to HIGH/LOW-level voltage) data as to
whether the accelerator is depressed or
re-
leased, and to input that voltage (as signals) to
the engine control module. The engine control module, based upon those signals, regulates the
idle-speed control motor.
TROUBLESHOOTING HINTS
l Voltage within the engine control module is ap-
plied, by way of the resistance, to the closed
throttle position switch.
When the foot is taken off the accelerator, the
closed throttle position switch is switched ON,
so the current is grounded.
As a result, the closed throttle position switch
terminal voltage changes from HIGH to LOW
level.
If there is an abnormal condition of the closed throt-
tle position switch output even though the results
of the checking of the closed throttle position
switch harness and of the component itself indicate
a normal condition, the cause may be presumed tobe one of the following.
TSB Revision
(1) Improper adjustment of the accelerator cable or the automatic-cruise-control cable.
(2) Improper adjustment of the fixed SAS.
