4. Eco Mode Control
General
D Eco mode control limits the air conditioning system performance during heating and cooling and
increases the amount of engine OFF time, thus improving the fuel economy.
D Eco mode control is activated by pressing the momentary type ECO switch on the instrument panel.
"ECO" is displayed on the heater control panel LCD during this control.
D Eco mode control during heating and cooling, and its cancel conditions are shown in the table below.

Heating Mode
D The required engine coolant temperature when starting the engine when the vehicle is stopped differs
from that when the vehicle is running. Therefore, the fuel economy has been improved by increasing the
amount of engine-off time when the vehicle is stopped.
D When the ECO switch is turned ON during heating, the A/C ECU stops the PTC heater operation.
Therefore, it takes a longer time to reach the set temperature than while the ECO switch is OFF.
D Engine coolant temperatures fluctuate greatly between when the vehicle is running and the vehicle is
stopped. The blower level changes accordingly.
D The hysteresis, which is used while the ECO switch is ON, is provided to prevent the blower level from
hunting due to fluctuations in the engine coolant temperature.
