Previous automatic transaxle have selected each gear shift using mechanically controlled throttle hydraulic pressure,
governor hydraulic pressure and lock-up hydraulic pressure. The electronically controlled transmission, however, electrically
controls the line pressure, throttle pressure, lock-up pressure and accumulator pressure etc. through the solenoid valve. The
electronically controlled transmission is a system which precisely controls gear shift timing and lock-up timing in response to
the vehicle's driving conditions and the engine condition detected by various sensors. It makes smooth driving possible by
shift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing,
squat and gear shift shock when starting off.
1. Gear Shift Operation
During driving the engine warm up condition signal is input from engine coolant temp. sensor to TERMINAL THW of the
engine control module, and the vehicle speed signal is input from the ABS speed sensor to skid control ECU, and are sent to
the engine control module through communication control. At the same time, the throttle valve opening signal is sent from
the throttle position sensor to the TERMINALS VTA1 and VTA2 of the engine control module, as the throttle angle signal.
2. Lock-Up Operation
When the engine control module decides based on each signal that the lock-up condition has been met, the current flows
through TERMINAL DSL of the engine control module to TERMINAL 10 of the electronically controlled transmission solenoid
to GROUND.
3. Stop Light SW Circuit
If the brake pedal is depressed (Stop light SW on) when driving in lock-up condition, a signal is input to TERMINAL STP of
the engine control module. The engine control module operates and cuts the current to the solenoid to release lock-up.
4. Overdrive Circuit
*O/D main SW on
When the O/D main SW is turned on, a signal is input to TERMINAL ODMS of the engine control module and engine
control module operation causes gear shift when the conditions for overdrive are met.
*O/D main SW off
When the O/D main SW is turned off, a signal is input into TERMINAL ODMS of the engine control module, and turns on
the O/D off indicator light. This activates the ECU, and the transmission system is controlled not to shift to overdrive.

NOTICE

Benzene or alkaline solutions may
damage the coated surface of the
screen
.


To prevent the battery from being
discharged, do not turn on the rear
seat entertainment system longer
than necessary when the engine is
not running.
The rear seat entertainment system can
be operated with the rear seat entertain-
ment system controller and buttons on the
DVD player unit. The system cannot be
operated by touching the switches on the
screen directly.
CAUTION
Do not disassemble or modify the
controller. It may cause an accident,
fire or electric shock.
NOTICE
Keep the controller away from direct
sunlight, high heat and high humidity.
These conditions could cause the
case to deform or the battery to ex-
plode or leak.
BEFORE USING THE CONTROLLER
(for new vehicle owners)
A battery is already set in the control-
ler with an insulating sheet, which pre-
vents the battery from being dis-
charged. Before using the controller,
remove the insulating sheet according
to the following procedure.

tainment system display.
The controller does not operate properly
when the signal reception portion of the
display is exposed to direct sunlight.
Block the display from direct sunlight.
CAUTION
To reduce the chance of injury in
case of an accident or a sudden stop
while driving, stow the controller in
the console box or front seatback
pocket when it is not in use.
NOTICE
