DRIVE MODE INTEGRATED CONTROL SYSTEM (IF EQUIPPED)
Plug-in hybrid vehicle
OJFHP056147L
The drive mode may be selected ac‐
cording to the driver's preference or
road condition.
The system resets to be in the ECO
mode, when the hybrid system is re‐
started.
If there is a problem with the instru‐
ment cluster, the drive mode will be in
ECO mode and may not change to NOR‐
MAL mode.
The mode changes whenever the DRIVE
MODE button is pressed.
NORMAL ECO
❈ When normal mode is selected, it is
not displayed on the cluster.
ECO mode (Active ECO)
Active ECO helps
improve fuel effi‐
ECO
ciency by control‐
ling certain en‐
gine and trans‐
axle system op‐
erating parame‐
ters. Fuel effi‐
ciency depends
on the driver's
driving habit and
road condition.
• When the DRIVE MODE button is
pressed and the ECO mode is selec‐
ted, the ECO indicator (green) will illu‐
minate to show that the Active ECO
is operating.
• When the Active ECO is activated, it
does not turn off even though the
engine is restarted again. To turn off
the system, press the DRIVE MODE
button again.
When Active ECO is activated:
• The acceleration may slightly be re‐
duced eventhough you depress the
accelerator fully.
• The air conditioner performance may
be limited
• The shift pattern of the automatic
transaxle may change.
• The engine noise may get louder.
The above situations are normal condi‐
tions when the active eco system is ac‐
tivated to improve fuel efficiency.
Limitation of Active ECO operation:
If the following conditions occur while
Active ECO is operating, the system op‐
eration is limited even though there is
no change in the ECO indicator.
• When the coolant temperature is low:
The system will be limited until en‐
gine performance becomes normal.
• When driving up a hill:
The system will be limited to gain
power when driving uphill because
the engine torque is restricted.
• When using manual mode:
The system will be limited according
to the shift location.
