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.’
2.Jack up the rear wheels, and then, setting a pick-up
stand and balancing machine in place, follow the sa me
procedure asfor front wheel measurements.

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

can be harmful to gasket and diaphragm materials

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.
