The transaxle control unit activates the shift control
solenoid valve “A” and deactivates the shift control
solenoid valve
“B”.Activation of the shift control solenoid valve “A”
releases-the pressure at the No.5a ports, which in
turn releases the pressure acting on the plugs at the
right and left of the shift control valve.Deactivation of the shift control solenoid valve
“B”results in rightward movement of both the
shiftcontrol valve and the right plug by line
pressureapplied through the No.5b port until the valve
isblocked by the stopper. This rightward movemeni
of the shift control valve opens the No.8 port ant
the line pressure is directed to the rear clutcr
exhaust valve.
This pressure is called
“4th pressure”.

2nd to 3rd Gear\(1) When the shift control valve comes into
3rd gear position
and the
3rd pressure is established, the pressure is
directed to the No.7 port of the end clutch valve through
the No.7 line. In this instance, the
3rd pressure is blocked
ahead by the end clutch valve and the check ball.
(2) If a shift to the
3rd gear is initiated, the pressrue begins to
be directed from the
2-3/4-3 shift valve to the front clutch
and the release side chamber of kickdown servo cylinder.
The same pressure also is directed to the chamber at the
right end of the end clutch valve through the No. 12 line.
During the shift to the
3rd gear, the pressure in the No. 12
line is regulated by the pressure control valve to a level
lower than the line pressure so that the No. 12 line pressureis not high enough to force the end clutch valve toward the
left.(3) Once the front clutch has been engaged and the kickdown
brake released, the No. 12 line pressure is raised to a level .
equivalent to the line pressure.
This means that the pressures at both ends of the end
j
clutch valve (or No. 6 line pressure and No. 12 line pressure)[are at the same level. However, as the area of the
#3 land
to which pressure is applied is larger than that of the
# 1
land of the end clutch valve, the valve is pushed to left, thusopening the No.
18 port. This allows the 3rd pressure (line
pressure) already established in the No. 7 line to be directedto the end clutch through
the..No.7 port. The end clutch is
now engaged.
Downshift from
3rd to 2nd Gear
(1) Both front clutch pressure and kickdown servo release
pressure are released, and therefore, the pressure in
theend clutch valve right end chamber is also released.
--
(2) This results in a rightward movement of the end clutclvalve by the
2nd pressure working on its left end, closingthe
No.7 port and releasing the end clutch pressurethrough the No.8 port. Now the end clutch is released,

be locked or unlocked (from the inside by using the
inside door lock knob at either front door, or from
the outside by using the door key), not only sewes

SEAT BELTSRZ3SBAS
On Federal and California vehicles automatic seat belts (Manualseat belts on vehicles for Canada) are installed on the front
seats and the
3-point seat belts with ELR on the rear seat, both
contributing to the enhanced safety and ease of use.
AUTOMATIC SEAT BELTS
GENERAL INFORMATION
The Automatic Seat Belts are designed to automatically fasten
themselves around the driver and front passenger as they get
into the vehicle and close the front door, thereby,
by a
combination of the lap belt, the knee protector, the corner pad
and the glove box pad (at the lower part of the instrument
panel), protecting them from second collisions during a
front-end crash or similar accident.
The lap belt for the driver’s seat is provided with the ELR
(ELR:Emergency Locking Retractor), and that for the front passen-
ger’s seat with the
ELR-ALR” to support the Child Restraint
System incorporated into the seat. (“ALR: Automatic Locking
Retractor) The buckle tilts toward front and inside helping the
belts be tight around the body.
The
tongue plate on the driver’s seat is provided with
energy-absorbing structure.
The automatic seat belts consist of a driving-device assembly,
shoulder belt, manual lap belt, knee protector, and other
components.
The driving-device assembly is composed of the slide anchor,
the release switch, the guide rail, the “fasten” switch, the
automatic seat belt motor relay, and the driving device.
There is an emergency-release button on the slide anchor; this
button can be used to release the shoulder belt in the event of
an emergency resulting from an accident, etc.

OPERATION OF AUTOMATIC SEAT BELTS
The operation of the Automatic Seat Belts is as follows.
(1) The belts fasten itself around the occupant when the front
door is closed with the ignition switch in the “ON” position.
(2) The belts release itself from the occupant when the front
door is opened with the ignition switch in the
*“ON” or
“LOCK” or “ACC” position.
(3) The belts cease to fasten itself around the occupant if the
ignition switch is turned to “LOCK” or “ACC” or when the
front door is opened during the belt motion.
(4) The belts for the driver’s and front passenger’s seats
operate independently of each other.

SWITCHOVER MECHANISM
The
ELR/ALR switchover mechanism is installed at the re
tor for the lap belt for the front passenger’s seat,
The component is an assembly supply item, and so is not to be
disassembled. Its construction and operation are, however, as
described below.
Gear
B is coupled with the shaft of the retractor; it rotates in ::the counterclockwise direction when the belt is pulled out.
Gear A is meshed with gear
B, and revolve in the same
direction as gear
B.The illustration
(19PO373) shows the condition when the belt is
completely rewound.
When the belt is pulled out completely, gear A revolves about
three times, and the gear A cam contacts rod A, thereby
pressing rod A. Rod A then presses the stopper, and the
stopper presses the sub
pawl.When the sub pawl is pressed, the internal lock mechanism
functions, and the belt pull-out motion becomes lock, thus
becoming ALR.
When the belt
is rewound about 600 mm (23.6 in.) from the
completely pulled-out position, gear A revolves in the clockwise
direction. with the result that the cam of gear A contacts rod
6and causes rod
B to be pressed.
Rod
B then presses the stopper, thus causing the sub pan -return. thereby unlocking the lock and making pull-out
freti.thus becoming ELR.

OPERATlON
Belt Fastening Motion
(1) If the belt is not in the fastening position (the
L.H. or R.H. door latch switch at Door Closed
position; the L.H. or R.H. “fasten” switch at
“ON” position) when the door is closed with the
ignition switch in the “ON” position, the belt
automatically moves to the fastening position.
For the period between the initiation and com-
pletion of the belt’s motion in the fastening
direction, the seat belt warning light either stays
lit or blinks.
Belt Releasing Motion
(1) When the belt is not in the release position, the
L.H. or R.H. release switch is in the “ON”
position, and the left or right door is opened, the
belt will automatically move to the release
position if the ignition switch is at either the
“ON”,“LOCK” or “ACC” position.
For the belt at the driver’s seat side moveover,
the belt will automatically move to the release
position if the
key is taken out while the belt is
fastened.
The buzzer sounds for approximately 0.7 secondsince the start of thebelt’s motion.When the belt is completely fastened, the
“fasten” switch is switched OFF and the motor
stops.(2) With a lapse of approximately 60 seconds after
the belt has stopped its fastening motion due to
foreign object wedged in the mechanism, the
protective timer of the control unit is activated
causing the motor output to the shut off.
When the belt completes its releasing motion,
the L.H. or R.H. release switch is turned OFF,
and the motor stops.
(2)If the belt is still in the process of releasing with
a lapse of approximately 60 seconds after the
start of motion, the protective timer in control
unit is activated causing the motor output to be
shut off.
At the same time, the buzzer sounds for
approximately 0.7 second.
