2) Transaxle Cooling
The transaxle cooling system ensures rapid warm-up and constant operating temperature resulting in
reduced fuel consumption and refined shift quality.
It also includes a cooler by-pass within the hydraulic system to allow sufficient lubrication to the transaxle
drivetrain in the event of a blockage in the transaxle cooler.
3) Shift Strategy
Gear Change
Transaxle gear change is controlled by the
TCU. The TCU receives inputs from various
engine and vehicle sensors to select shift
schedules and to control the shift feel and
torque converter clutch (TCC) operation at each
gear change.
Coast down
Coast down down shifts occur at 0% pedal
when the vehicle is coasting down to a stop.
Torque Demand
Torque demand down shifts occur
(automatically) when the driver demand for
torque is greater than the engine can provide at
that gear ratio. If applied, the transaxle will
disengage the TCC to provide added
acceleration.

(2) Temperature control
The blowing air temperature is controlled by the temp actuator and the set temperature can be checked
via the LCD display.
Manual control
The discharge air temperature is controlled by the temperature control dial. The driver can select one
of the 31 levels.
Auto control
When pressing the AUTO switch, "AUTO" is shown on the display and the fan speed and air distribution
mode are adjusted automatically to keep interior temperature to the set temperature. In full AUTO mode,
the FATC receives various signals such as the indoor temperature, ambient temperature, engine coolant
temperature, sunlight, from different sensors to control the A/C compressor, mode actuator, intake
actuator, temp actuator, blower motors, etc. to keep indoor environments fresh.
Max. cooling/heating control (AUTO mode)
If the temperature is set to the lowest level (Lo) or highest level (Hi), the system will go into the maximum
cooling or maximum heating mode regardless of the sensor signals.

Initial fan speed control for cooling/heating
Cooling start control
by the air flow from the vent. Therefore, at the initial operation stage, the hot air is discharged to the
windshield (DEF mode) for about 5 seconds. -
Heating start control
When the engine coolant temperature is low or the wind temperature is not warmed up sufficiently,
the driver might feel uncomfortable by the air flow from the vent. Therefore, the fan speed is set to the
1st stage and the cool air is sent to the windshield until the coolant temperature increases to the
proper level (DEF mode). As the engine coolant temperature goes up, the mode is changed to
Defrost & Foot mode or AUTO mode to increase the speed of blower motor. This control is cancelled
control time must not exceed 10 minutes. -

(4) Air source control
The air source selection is made by the intake actuator. The driver can see the air source mode through
the switch's indicator and the LCD display.
Manual control
Press the air source selection switch to control the air source selection door manually. The air source
mode is switched
between the fresh air and recirculation alternatively each time the switch is pressed.
Auto control
In auto mode, the basic setting for the air source is fresh air. When the ambient temperature is high
during cooling,
the air source is changed from fresh air to recirculation to lower the temperature.
Control by vehicle speed (heating)
The air source selection is controlled in accordance with the vehicle speed while driving. Operating
conditions and control process are as follows:
AUTO mode
When the vehicle speed is 45 km/h or lower in fresh air mode, the air source door is open 30% of its
maximum opening. If the vehicle speed is 65 km/h or more, then
the air source door is completely open. -

and the electric fan 7.5V or higher.
