Limitations of ECO mode
If the following conditions occur while
E
CO mode is operating, the system
operation is limited even though there is
no change in the ECO indicator.

[ When coolant temperature is low:
The system will be limited until engine
performance becomes normal.

[ 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 in manual
shift mode using the paddle shifter.
The system will be limited according to
the shift location.
SPORT mode
SPORT mode provides sporty
but firm riding.
In SPORT mode, the fuel
efficiency may decrease.

[ When SPORT mode is selected, the
SPORT indicator will illuminate on the
instrument cluster.

[ Whenever the engine is restarted, the
drive mode will revert back to ECO
mode. If SPORT mode is desired, re-
select SPORT mode.

[ When SPORT mode is activated:
- The engine rpm will tend to remain raised over a certain length of time
even after releasing the accelerator
- Upshifts are delayed when accelerating
SMART mode
SMART mode selects the
proper driving mode among
ECO, COMFORT and SPORT
by judging the driver's
driving habits (i.e. mild or
dynamic) from the brake pedal
depression or the steering
wheel operation.

[ Press the DRIVE MODE button to
activate SMART mode. When SMART
mode is activated, the indicator
illuminates on the instrument cluster.

[ The vehicle starts in SMART mode,
when the engine was turned OFF in
SMART mode.

[ SMART mode automatically controls
gear shifting patterns, engine torque,
in accordance with the driver's driving
habits.
Information

[When you mildly drive the vehicle
in SMART mode, the driving mode
changes to ECO mode to improve fuel
efficiency. However, the actual fuel
efficiency may differ in accordance
with your driving situations (for
example, upward/downward slope,
vehicle deceleration/acceleration).

[ When you dynamically drive the
vehicle in SMART mode by abruptly
decelerating or sharply curving, the
driving mode changes to SPORT mode.
However, it may adversely affect fuel
economy.
