GENERAL Precautions before Service . .
Caution
1.Before connecting or disconnecting the negative
be sure to turn off the ignition and
the lighting switch.
(if this is not done, the possibility semi-
conductor parts being damaged.)
2.After completion of the work steps [when the bat-
tery’s negative terminal is connected], warm
up the engine and allow it for approximately
five minutes under the conditions be-
low, in order to stabilize the engine condi-
tions, and then check to be sure that idling’ is
satisfactory.

VEHICLE WASHING
If high-pressure car-washing equipment or steam car -washing
equipment is used to wash the vehicle, be maintain
the spray nozzle at a distance of at ‘least 300 mm (12 in.)
from any plastic parts and all opening parts (doors , luggage
compartment, etc.).
APPLYING ANTI-CORROSION
OTHER UNDERCOAT AGENTS.,
Be careful not to adhere oil or grease to the heate d oxygen
sensor. If adhered, the sensor may malfunction.
Protect the heated oxygen sensor with a cover befor e applying
anti-corrosion agent, etc.
SCAN TOOL
To operate the scan tool, refer to the “MUT-II OPER ATING
INSTRUCTIONS”.
Caution
Turn the ignition switch off befoie connecting and discon-
necting the scan tool.

FRONT WHEEL MEASUREMENTS
1. Jack up the rear wheels, and place an axle at
the designated part of the side sill.
2. Jack up the front wheels and set, a pick-up stan d and
balancing machine in place.
Caution
1.Set so that the front and rear of the vehicle are
at the same height.
2. Release the parking brake.
3.Rotate each wheel manually and check to be sure
that there is no dragging.
3. Use the engine to drive the tyres, and then make the
measurement.
Caution
1.If an error is indicated in the state of engine drive,
motor drive can be used concurrently.
2. Do not operate the clutch suddenly, or increase or reduce speed suddenly during the work.
REAR WHEEL MEASUREMENTS
1. Jack up the front wheels, and ‘place an, ‘axle s tand at
the designated part of the side sill.’

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.

1.Spark plugs must spark properly to assure proper engine
performance and reduce exhaust emission
Therefore, they should be periodically with new
ones.

(Check ‘fluid level)
Engine (Non-turbo)>
1. Position the vehicle on a level surface.
2. Start engine and allow to idle in PARK for at le ast 60
seconds. The warmer the transaxle fluid, the more
accurate the reading.
3.While sitting in driver seat, apply brakes and plac e gear
selector in each position. Return gear selector to PARK.
4. Raise hood and remove transaxle fluid level indi cator
(dipstick) and wipe clean with a suitable shop towe l.
5.
dipstick and verify it is seated in fill tube.
Caution
Do not overfill automatic transaxle, leakage or dam age
can result.
6. Remove dipstick, with handle above tip, take flu id level
reading. If the vehicle has been driven for’ at fea st 15
minutes before inspecting fluid
transaxle can be
considered hot and reading should be above the WARM
mark. If vehicle has run for less than 15 minutes a nd
more than 60 seconds, transaxle can be considered w arm
and reading should be above ADD mark. Add fluid onl y
if level is below ADD mark on dipstick when transax le
is warm.
Engine (Turbo) and Engine>
1. Drive until the fluid temperature reaches the us ual
, temperature
2. Place 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 n ecessary
to be sure that fluid level check is accurate.

GENERAL Maintenance
4.Before removing dipstick, wipe all dirt from area around
dipstick. Then take out the dipstick and check the condition
of the fluid.
Further investigation of the transaxle is necessary if,
l the fluid smells burnt.
l the fluid color is brown or black.
l metal particles can be seen or felt on the dipstick .
5.Check to see if fluid level is in “HOT” range on dipstick.
If fluid level is low, add ATF until level reaches “HOT”
range. Low fluid level can cause a variety of condi tions
because it allows pump to take in air along with fl uid.
Air trapped in hydraulic circuit forms bubbles which make
fluid spongy.
Therefore, pressures will be erratic. Improper filling can also raise fluid level too hig h. When
transaxle has too much fluid, gears churn up foam a nd
cause same conditions which occur with low fluid le vel,
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 flu id
escaping from transaxle vent where it may be mistak en
for a leak.
6. Be sure to examine fluid on dipstick closely.
(Change fluid)
Engine (Non-turbo)>
1.Place a drain container with a large opening, under the
transaxle oil pan.
2. Loosen the pan bolts and tap the
at one comer’
to break it loose allowing fluid to drain, then rem ove the
oil pan.
3. Install a new filter and O-ring on bottom of the valve
body.
4. Clean the oil pan and magnet.
Apply the specified sealant to the oil pan.

6. Start the engine and allow it to run at idle for at least
one minute. Then, with parking and service brake ap plied,
move the selector lever momentarily to each positio n,
