Eco mode will lower the shiftpoints to a lower RPM.
And ECO mode reduces the A/C performance to additionally save fuel. 2nd bullet point below from the owner's manual.
When ECO mode is activated:
• The acceleration response may be
slightly reduced if the accelerator
pedal is depressed moderately.
• The air conditioner performance
may be limited.
• The shift pattern of the automatic
transmission may change.
• The engine noise may get louder.
The above situations are normal
conditions when ECO mode is acti-
vated to improve fuel efficiency.
Limitation of ECO mode operation:
If the following conditions occur while
ECO mode is operating, the system
operation is limited even though
there is no change in the ECO indi-
cator.
• When the coolant temperature is
low:
The system will be limited until
engine performance becomes nor-
mal.
• When driving up a hill:
The system will be limited to gain
power when driving uphill because
engine torque is restricted.
• When driving the vehicle with the
automatic transmission gear shift
lever in manual mode.
The system will be limited accord-
ing to the shift location.
