CHECK OF RETURN TO THE SET SPEED BEFORE
CANCELLATION (1) Set the auto-cruise control.
(2) Check to be sure that the auto-cruise control is
cancelled
when either of the operations below is performed.
@ The brake pedal is depressed.
@ The clutch pedal is depressed. @ The shift lever is moved to the “N” range.
CAST>
(3) Turn the control switch to RESUME position and release
(RESUME switch
ON*OFF) while driving at a vehicle
speed of approximately 40 km/h (25 mph) or higher.
(4) After switching RESUME switch to OFF, check to be sure that there is a return to the auto-cruise control speed before
it will be
cancelled and the vehicle will travel at the constant
speed.
ACCELERATOR CABLES INSPECTION AND
ADJUSTMENT

(I) Turn air conditioning and lights OFF. Inspect and adjust at no load.
(2) Warm engine until stabilized at idle.
(3) Confirm idle speed is at prescribed rpm.
(4) Stop engine (ignition switch OFF).
(5) Confirm there are no sharp bends in accelerator cables.
(6) Check inner cables for correct slack.
(7) If there is too much slack or no slack, adjust play by the following procedures.
0 Remove the actuator’s protector.
0 On models with an SOHC engine, turn the ignition
switch to the ON position (without starting the engine)
and leave in that condition for approximately 15
seconds.

DATA LINK AND TEST
FLUID LEVEL AND CONDITION
1. Drive until the
fluid
temperature
reaches the
usual tem-
perature
[70-80°C (160- 18O”F)l.
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 necessary
t0
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.
lIf there
is a noticeably
great
amount
of metal particles in
the
fluid.
5.Check to
see if fluid
level is in “HOT” range on dipstick.
If
fluid
level is low, add automatic
transaxle
fluid
until level
reaches “HOT” range.
Low
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
automatic
transaxle
fluid.
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.
CONTROL CABLE
Whether control
cable is properly
adjusted
can be confirmed
by
checking

whether park/neutral
position
switch is perform-
ing
well.
1.
Apply
parking brakes and service
brakes securely.
2. Place
selector
lever
to
“R” range.
3. Set ignition
key to
“ST” position.
4.
Slowly
move
the
selector
lever
upward
until it
clicks as it
fits in
notch of “P” range. If starter
motor
operates
when
lever makes a click, “P”
position
is correct.
5.Then slowly
move
selector
lever to “N” range by
the
same
procedure as in foregoing
paragraph. If starter
motor
operates

when selector
lever
fits in ‘IN”, “N” position
is correct.
6.
Also check to be sure the
vehicle
doesn’t
begin to move
and
the
lever
doesn’t
stop
between
P-R-N-D.
7. The control
cable is properly
adjusted if, as described
above,the
starter
motor
starts
at both the

“P” range and the

“N” range.

SHIFT PATTERNS
Two

shift patterns
are pm-stored
in the
control
‘unit of
this transaxle.
One is the
power
pattern
(for more powerful
performance), and
the
other
is the
economy
pattern
(for
improved

fuel consumption
and quieter
operation).
(Refer to
the

diagram below.)
The
driver
can select
and switch to the
desired
pattern
by
using
the
power/economy
select

switch on the
center
console.
The solid lines
shown
in these
shift patterns
indicate
up-shifts,
and
the
broken lines indicate. down-shifts. The reason why there

is a difference
between
the
shift points for
up-shifts
and for

down-shifts is so that up-shifts
and down-shifts will not
occur frequently
when
driving
at
a speed in the
vicinity of the
shift
point.
When the
vehicle

is stopped,
there
is a shift to -2nd gear
in order
to
obtain
a suitable
“creeping”, but
when the accelerator
pedal is
then
depressed
the
vehicle
starts
off in 1st gear.

SELECTOR LEVER OPERATION CHECKM23flAE
1. Shift selector lever to each range and check that lever
moves smoothly and is controled. Check that position
indicator is correct.
2.Check to be sure the selector lever can be shifted to each
position (by button operation as shown in the illustration).
3. Start the engine and check if the vehicle moves forward
when the selector lever is shifted from N to D, and moves
backward when shifted to R.
4. When the shift lever malfunctions, adjust control cable and selector lever sleeve. Check for worn shift lever
assembly sliding parts.
NOTE
To move the selector lever from the “P” position to any
other position, first turn the ignition key to any position
other than “LOCK (OFF)” and depress the brake pedal.

KEY INTERLOCK MECHANISM CHECKM23FUAA
Completely stop the vehicle and switch OFF the engine before
making the check.
1.Check to be sure that, under the following conditions, the
selector lever cannot be moved from the “P” position to
any other position.
Also check, at the same time, that the button cannot be
pressed.
Ignition key position:“LOCK (OFF)“, or removed
Brake pedal: Depressed
2.Check to be sure that, under the following conditions, the selector lever can be moved from the “P” position to any
other position.
Press the button a few times and check to be sure that the
selector lever moves smoothly.
Ignition key position: “ACC”
Brake pedal : Depressed
Button: Pressed
3.Check to be sure that, at all positions of the selector lever
(other than “P”), the ignition key cannot be turned to the
“LOCK (OFF)” position.
Check to be sure that the ignition key smoothly turns to the
“LOCK (OFF)” position when the selector lever is then set
to the “P” position and the button is released.
If a malfunction is discovered when following the above
checking procedures,either adjust or check the key
interlock cable mechanism. (Refer to
P.23-97.)
